    • Despite economic, health and social costs, hearing loss is often ignored — why?

      Published 38 days ago
      • Hearing loss

      By Aylin Altan, PhD, OptumLabs; Margaret Wallhagen, GNP, PhD, University of California, San Francisco; and Samantha Noderer, MA, OptumLabs

      More than 38 million Americans have hearing loss, but fewer than one in three of them treat it. Why is that?

      For some, it’s the cost and inconvenience of purchasing, fitting, adjusting and maintaining hearing solution equipment. Others worry about appearing older or calling attention to their hearing loss. Many older adults don’t appreciate how significant their hearing loss is because it deteriorates gradually. Other adults don’t think it’s problematic to let their hearing loss go untreated ― but could it be? What are the consequences of missing or misinterpreting every day conversations and environmental cues?

      We know from past studies that hearing loss is associated with isolation and depression. Over the last several years, we’ve also learned that those with untreated hearing loss may pay a high price in terms of health issues as well as health care costs and use of health care services.

      This is an important topic for our society as more and more of us live to advanced age. We need to change the conversation about the importance of hearing ― emphasizing that hearing loss is more than just an inconvenience — in order to help individuals live healthier lives.

      Over the past 18 months, OptumLabs has conducted a collaborative research initiative focused on the long-term health impacts of hearing loss. For this initiative, OptumLabs assembled clinical, health services research and observational data experts from Johns Hopkins University, AARP Services Inc., the University of California San Francisco (UCSF), the Hearing Loss Society of America and the OptumLabs research staff. We analyzed data from the OptumLabs Data Warehouse, including de-identified retrospective administrative claims, socioeconomic status and electronic health record data for privately insured and Medicare Advantage enrollees.

      OptumLabs findings: The health impact of untreated hearing loss

      Using OptumLabs data, the team analyzed data from adults, age 50+, who had commercial or Medicare Advantage insurance during 2000–2016. We compared those with untreated hearing loss (based on claims data) with those who had no evidence of hearing loss over two, five and 10 years. The results were published as two papers in JAMA Otolaryngology—Head & Neck Surgery. One paper focused on key comorbid conditions associated with untreated hearing loss. The other paper looked at health care costs and service utilization  associated with untreated hearing loss.

      In comparison to people without hearing loss, the study found that over a period of 10 years, people with untreated hearing loss:

      Had more health problems untreated hearing loss was associated with an increased
      attributable risk of dementia (3.2 per 100 persons), depression (6.9 per 100 persons) and falls (3.6 per 100 persons).

      Hospital icon

      Spent more time in the hospital those with untreated hearing loss experienced almost 50 percent more hospital stays and had a 44 percent higher risk for being readmitted to the hospital within 30 days.

      Money icon

      Spent more money on health care total health care costs for those with untreated hearing loss were on average of 46 percent higher ($22,434 more).

      This study reinforces existing data on the association between untreated hearing loss and health conditions such as depression, dementia, and falls ― where the effect increased over time. It’s also the first 10-year study of the health care costs and utilization associated with untreated hearing loss.

      Something to talk about

      These findings, taken with the results of other studies, can help support efforts to improve the quality of life and remove barriers to treatment for people with hearing loss. Early screening and intervention, reducing the stigma of hearing loss and making hearing loss treatments and services affordable and available are all important opportunities to consider.

      Additional UCSF research has been done on the benefits of streamlined hearing loss screening and educational protocols in primary care settings. It’s been found that patients are more motivated to address their hearing loss when providers share information on ways it can be managed. Clear and empathetic communication is critical to the success of these protocols.

      Miscommunication with health care providers may be more common for people with hearing loss. Low treatment adherence (for example, not taking medications appropriately or not following up with doctors) is a known downstream effect of poor patient-provider communication in the hospital or doctor’s office. This can lead to more health complications, hospitalizations and hospital readmissions.

      There are things that providers can do to make sure their patients understand and remember their advice about the importance of hearing and hearing loss treatments and services. It’s also important to discuss the real concerns that patients have about stigma, aging, cost and inconvenience.

      Best practices when speaking to a person with hearing loss:

      • Always face a person so that they can read your lips (people with hearing loss do this instinctively).
      • Eliminate as much extra background noise as possible (music, loud fans, side conversations).
      • Don’t stand with your back to a bright window because your face will not be as clearly seen.
      • If you’re asked to repeat yourself, try to articulate your words more instead of just talking louder (shouting doesn’t help) and try to rephrase what you said (use different words).
      • Ask the person to repeat what they heard to make sure they understood it and to help them remember.
      • Write information down, especially if it’s really important.

      Key hearing loss topics to communicate with patients and family members:

      • Address any personal concerns a patient may have about their hearing loss and hearing loss treatment, including the appearance of wearing hearing solutions, fears of aging and financial implications.
      • Emphasize the importance of hearing:
        • Leaving hearing loss untreated may impact communication and relationships, and ultimately lead to more health problems (for example, depression, dementia and falls), time spent in the hospital, days spent in clinic and money spent on health care services.
        • It’s important to screen for hearing loss regularly, take steps to prevent it or modify its impact and treat it as soon as possible.
      • Discuss treatment options:
        • For mild to moderate hearing loss, more affordable over-the-counter options are becoming available that consumers can adjust themselves.
        • Hearing aid and hearing services coverage varies by insurance plan. Many policy advocates are pushing for expanded coverage across commercial, Medicare and Medicaid insurance.

      Doctor and patient talking

      Discussions about why hearing matters and how to avoid the negative effects of hearing loss should start early with adults in primary care. Combined with policy efforts underway to improve access to treatments and services, the future for those with hearing loss may begin to sound more positive.

    • On the Front Lines of Anaphylaxis: Using Data to Save Lives

      Published Oct 09 2018, 12:38 PM
      • Emergency medicine
      • Allergy

      By Ronna Campbell, MD, PhD,  Megan Motosue, MD, and M. Fernanda Bellolio, MD, Mayo Clinic

      Anaphylaxis is a serious, potentially life-threatening allergic reaction that affects millions of Americans. Today, nearly 15 million people in the U.S. have a food allergy and numbers are increasing.

      Symptoms of anaphylaxis can occur within seconds following exposure to an allergen such as a medication, food, or an insect sting. This triggers an immune system response that can cause hives, itching, nausea, vomiting, diarrhea, narrowed airways, difficulty breathing, and may decrease blood pressure causing dizziness and loss of consciousness. Immediate treatment is critical.

      As Mayo Clinic emergency department (ED) clinicians, we work on the front lines of treating anaphylaxis and wanted to know whether there were ways to better treat anaphylaxis, including preventing reoccurring ED visits.

      To answer our questions, we conducted several studies on national trends in anaphylaxis-related ED visits and outcomes using the OptumLabs data, which includes de-identified claims for privately insured and Medicare Advantage enrollees over many years. Our research is helping us to improve anaphylaxis prevention and treatment protocols at Mayo Clinic, with potential to help the millions of Americans who suffer from this potentially deadly reaction.

      Trends in anaphylaxis-related ED visits and outcomes

      Overall, we’re seeing increased instances of anaphylaxis among younger people caused by food (nut allergies) and by medications taken by older people, especially those who have complex health conditions. The rising cost of injectable epinephrine, the primary treatment for anaphylaxis, is also concerning because it is making it more difficult for some patients to access the proper tools for management.

      Using the de-identified OptumLabs data, we evaluated trends in anaphylaxis ED cases across three categories: the most common triggers, risk factors for severe cases, and prevention. Here’s what we’ve found:

      1.  Anaphylaxis is increasing and is frequently caused by food, medications and venom.

      Looking across 56,212 ED visits in claims data for patients of all ages, we reported in the Journal of Allergy and Clinical Immunology: In Practice that rates of ED visits for anaphylaxis doubled between 2005 and 2014 (14.2 per 100,000 to 28.6).

       

      Anaphylaxis ED visits doubled between 2005 and 2014

      Line graph shows anaphylaxis ED visits per 100,000 enrollees doubled between 2005 and 2014.

       

      The most common allergic reactions were due to medications, food, and venom (by way of stings from bees, wasps, yellow jackets, hornets, and fire ants). There was another large category of unspecified triggers, which may be cases where the allergen could not be identified in the ED or the diagnosis was not entered as a claim.  

      We also found that anaphylaxis cases were excessively high in children 5-17 years old, mostly due to food allergies. We reported in Pediatric Allergy and Immunology  that among 7,310 children, ED visits for food-induced anaphylaxis more than tripled (6.40 per 100,000 to 20.05) from 2005 to 2014. Peanuts were the leading cause, while ED visits related to tree nuts and seeds had an almost a four-fold increase. Other studies have found that food-related allergies now impact 1 in 13 children, an average of two students in a typical classroom.

      2.  Anaphylaxis severity is increasing and patients who are older, have chronic disease, or have medication allergies are most at risk.

      Looking across the 56,212 ED visits for patients of all ages with anaphylaxis, we reported in the Journal of Allergy and Clinical Immunology Practice that over time more people were admitted to the hospital, placed in the intensive care unit (ICU), or underwent endotracheal intubation (placement of a plastic tube inserted through the mouth to carry air to the lungs) for treatment, suggesting that severe anaphylaxis cases may be increasing.

      To understand why, we looked at the characteristics of the 38,695 patients who had these severe cases of anaphylaxis. We reported in Annals of Allergy and Asthma Immunology that the most common patient risk factors were being 65 years or older, having multiple health conditions (particularly heart or lung disease), or an allergic reaction to medication.

      3.  Many patients do not get epinephrine or see an allergist to prevent and manage future reactions.

      We also wanted to know what patients were doing once they left the ED to help prevent and treat potential future incidents. National guidelines recommend that all patients who are treated in the ED for anaphylaxis receive and fill a prescription for injectable epinephrine — e.g. commonly known by the brand name EpiPen, but includes other brand names: Adrenaclick and Twinject  ― and follow-up with an allergy/immunology (A/I) specialist. But the preventive follow-up isn’t happening for many.

      We reported in the Journal of Allergy and Clinical Immunology: In Practice that among 18,279 patients of all ages who were discharged after an anaphylaxis-related ED visit, only 46 percent filled a prescription for injectable epinephrine and only 29 percent had an A/I follow up within one year of the ED visit. This suggests that many patients may not be prepared to manage future episodes. Additional efforts are needed to identify system-based and patient barriers to guide strategies for improvement.

       

      Rate of preventive steps after an anaphylaxis ED visit among patients

      Graph shows for every 10 people, 2.9 see an allergist and 4.6 fill an epinephrine Rx after the ED.

       

      We need to do more research to determine whether the issues lie largely in patients not receiving a prescription for injectable epinephrine, or whether many patients are just not filling their script. In light of escalating costs of these devices, it will be important to examine the patient out-of-pocket costs (co-payments, co-insurance, and deductibles) that may be barriers to filling prescriptions. Recent FDA-approval of the first generic version of injectable epinephrine and extension of the expiration dates by one year are two important steps in making this preventive treatment more accessible to patients who need it.

      Among those patients who filled an EAI prescription within a year, most (58 percent) did so within one day of discharge. The immediate days after discharge — when patient awareness is heightened after being very sick in the ED ― is an important window of opportunity for prevention-targeting interventions.

      How we’re using this data to improve clinical practice

      At Mayo Clinic, we use a multidisciplinary approach to improve how we work with those at risk of anaphylaxis by 1) appropriately observing patients, 2) educating our staff about anaphylaxis prevention and treatment best practices, and 3) preparing patients with the knowledge and tools to prevent future events once they leave the ED.

      Here’s what we’ve done based on our research and experience:

      • Created an observation unit protocol. Sometimes hours after the symptoms of anaphylaxis clear, patients may experience biphasic reaction, or a second onset of anaphylaxis. Our protocols make it easy for clinicians to keep patients in an observation area to monitor for recurrent symptoms, and avoid more costly hospital admissions. We’re currently doing research with our patients to better understand who is at risk for these rare but serious reactions so that we do not keep anyone longer than needed.
      • Recruited nurses to provide training. All of our nurses are trained to teach patients how and when to use injectable epinephrine. This takes some of the burden off ED providers and better prepares our patients to safely manage their allergy once they leave the ED.
      • Ensured patients have a referral to an allergist. Our ED providers are trained to refer all patients to an allergist so they can learn more about their allergy and how to best treat it.

      Another study that we conducted using OptumLabs data highlighted the importance of arming patients with clear and actionable information after visiting an ED, especially those with a food allergy. Patients who had anaphylaxis due to a food trigger were more likely to return to the ED to be treated for anaphylaxis, as were those who had a history of asthma or had a more severe initial reaction requiring admission to an ICU. That’s why it’s particularly important that these patients understand how to prevent and treat future reactions.

      Unfortunately, as the rates of allergies and asthma continue to rise, the demand for treatment also grows. Using data and research, we will be able to help improve access and quality of care delivered to people suffering from these awful conditions.

    • Improving quality of life after cancer care

      Published Aug 07 2018, 10:39 AM
      • Cancer

      By Henry J Henk, PhD; Darshak Sanghavi, MD; and Samantha Noderer, MA, OptumLabs

      Researchers and clinicians have been working hard for decades to improve the quality of U.S. health care delivered to patients. In particular, our country has made significant improvements in the treatment of cancer. Overall, the death rate from cancer in the U.S. fell by 25 percent from 1990 to 2014. And now, approximately 70 percent of people diagnosed with cancer of any kind may expect to live five years or more.

      But as we get better at saving lives, how can we do more to preserve quality of life after treatment? And how can we accelerate broader use of treatment strategies that have a positive impact over both the short and long term? At OptumLabs®, we’re collaborating with cancer experts from our partner community around a longitudinal data set to understand and act on these important questions — to better understand what helps patients live healthier, higher-quality lives.

      The heart of the matter

      Let’s take pediatric leukemia as an example. With today’s advanced medicine and technology, the vast majority of kids diagnosed with this serious cancer survive. Yet, these young survivors often face health problems in the future caused by the side effects of cancer treatments. For example, a very effective and powerful chemotherapy drug called doxorubicin has been associated with serious heart problems 5, 10 or 20 years down the line.

      A breakthrough occurred in 1995 when the FDA approved a new drug called dexrazoxane, which is designed to protect the heart from damage caused by powerful chemotherapy. The drug was first approved and used in patients with breast cancer, but its use was unproven for other types of cancer. In 2004, a study in the New England Journal of Medicine found pediatric patients with acute lymphoblastic leukemia (ALL) who were given dexrazoxane had less heart cell damage (indicated by an increase in cardiac troponin) in the short term, without compromising the effectiveness of the chemotherapy they were receiving. In 2014, dexrazoxane received FDA-designated orphan drug status for prevention of heart damage in children and adolescents receiving chemotherapy. Over the next few years, more research was published on the favorable effects of this drug.

      Some may have expected this collection of early evidence to help change pediatric cancer care in recent years. But without more long-term evidence about the safety and effectiveness of dexrazoxane, is it enough to change practice? We turned to the OptumLabs data to find out.

      OptumLabs analysis

      Using de-identified OptumLabs claims data; we studied 499 pediatric patients with acute myeloid leukemia (AML) or acute lymphoid leukemia (ALL) who received doxorubicin chemotherapy between January 1993 and December 2010. Only 16 (3.2 percent) were treated with the heart-protecting dexrazoxane. A similar study on a different dataset published in Pediatric Blood Cancer found even lower use among patients with AML and ALL between January 1999 and December 2009. This was not surprising, given the lack of favorable evidence during that time period.

      1993–2010, OLDW

       

      We looked back at the OptumLabs data for 2014–2016 to see if the FDA designation and favorable research were having an impact, and we found that rates had increased somewhat. Among 299 patients with several types of common pediatric cancers (AML or ALL as well other leukemia/lymphoma, CNS/brain, sarcoma/bone) who received doxorubicin, 28 (9.4 percent) received dexrazoxane.

      Our initial findings suggest that early evidence on short-term effectiveness of a drug is often not enough to get clinicians to use it. We also know that there are no guidelines recommending routine use of dexrazoxane, which are key drivers of broad uptake. There are some treatment protocols that recommend it for pediatric patients receiving a high dose of chemotherapy (cumulatively over 200 mg/m2). Nevertheless, this preliminary analysis helps us ask follow-up research questions that can get at the long-term outcomes associated with the drug and help identify the right patients for this treatment.

      That’s why the OptumLabs Data Warehouse — which contains data spanning 25 years and covers more than 160 million de-identified lives across claims and clinical information — can help us explore important questions about cancer care and survivorship.

      The OptumLabs Cancer Research Collaborative

      With this in mind, last year, The American Cancer Society and OptumLabs co-founded the OptumLabs Cancer Research Collaborative (CRC) to accelerate cancer research and translation through collaborative studies and research-driven data improvements. We’re convening expert participants from organizations such as Stand Up To Cancer, Harvard Pilgrim Health Care Institute, Mayo Clinic, University of California Health, Yale and leadership from Optum Clinical Services and UnitedHealthcare Oncology.

      The CRC is looking not only at cardiac impacts of cancer therapies, but at many other issues in cancer treatment and survivorship. The OptumLabs data contains information on components such as benefit design and prior authorization that are well suited for studying the cost of cancer care — one of the biggest challenges for survivors and the health care system at large — as well as long-term outcomes. Through this, we’re answering questions that can help us determine what quality care looks like, such as:

      • How are cancer care guidelines being followed?
      • How are cancer survivors using the health care system — what does it cost and is it effective?
      • What kind of chemotherapy toxicities are manifesting in survivors long-term?
      • What secondary risk factors are leading to poor health outcomes in cancer survivors — such as obesity and smoking?

      There are roughly 20 cancer-related research projects underway, and several recently completed on topics such as breast cancer survivorship care, emergency department use among colorectal cancer patients and cardio-toxicities associated with new cancer treatment drugs.

      With support from AARP, we are also working on developing quality measures with our partners at Tufts Medical Center that help identify cancer care-related adverse events and medical errors. Better measurement in these areas could help clinicians inform patients about treatment options, surface areas for health care delivery improvements and guide researchers and policymakers.

      It is gratifying that more people are surviving cancer than ever before. Just as important, OptumLabs and our partners are working to make sure that our health care system not only knows which treatments work, but also which treatments may lead to a higher-quality life for patients down the road.

    • Care after delivery: Finding opportunities to prevent diabetes in mothers

      Published May 02 2018, 10:37 AM
      • Diabetes

      By Judith Bernstein, PhD, with Lois McCloskey, DrPH, Boston University School of Public Health

      Having a baby is one of the most wonderful and, at times, difficult experiences in a woman’s life. Changes in hormones and fluid levels put a woman’s body to the test during pregnancy, requiring the body to adapt even at the cell level. In about 9 percent of pregnant women, this stress can impact the way their cells process sugar and cause a type of diabetes during pregnancy known as gestational diabetes (GDM). Women with GDM are at an increased risk for developing type 2 diabetes (T2DM) later on. In fact, up to 60 percent of women with GDM will be diagnosed with T2DM in the decade after they deliver.

      Because of this risk, clinical guidelines recommend that women who have GDM during pregnancy get postpartum glucose testing within weeks after delivery and then regular blood sugar testing with a primary care doctor after that. Unfortunately, this does not always happen. This is a missed opportunity to make lifestyle changes and start medications that can prevent or delay T2DM, if initiated in time.

      Our research team from Boston University School of Public Health turned to the OptumLabs data to get a big picture of what sends women along a path for diabetes prevention after GDM, or fails to do so. Our findings suggest new strategies to ensure women receive appropriate care around this important life event.  

      Defining the problem and opportunities with OptumLabs data

      Our goal was to learn about the barriers to — as well as the opportunities to increase — postpartum glucose testing and primary care follow-up. We analyzed OptumLabs Data Warehouse claims data for 12,655 commercially insured women who had GDM and followed them for a three-year period from 2005 to 2015.

      When we looked at the patterns of follow-up among these women, only 24 percent received both the recommended glucose monitoring and primary care contact. Almost half had no glucose testing, and less than half had contact with any kind of primary care after delivery. We also found a high rate of women ended up developing T2DM. You can see the breakdown of follow-up care and T2DM onset in the flow diagram below.

      Figure 1. Pathways to follow-up after a GDM delivery and T2DM onset

      Care pathway diagram for women with GDM from delivery to 3 years later, and rate of T2DM onset.
      A new T2DM diagnosis was recorded for 7.6% of the women who had follow-up within three years of a GDM delivery. Among the 32.7% of women who had no follow-up of any kind, an unknown number may have had undiagnosed T2DM or rising glucose levels.

       

      We next looked at predictors of recommended testing and care (using a “multivariable analysis method”) and found one consistent factor: primary care. Women who visited a primary care doctor in the year before they were pregnant were 1 to 3 times more likely to receive appropriate glucose testing after delivery, as well as testing and primary care at one year. Likewise, these women were also 3.5 times more likely to get recommended testing and care at three years post-delivery.

      Complex problems call for innovative, collaborative solutions

      These results highlight a critical need for innovative care models that connect women with primary care from adolescence through maternity and into older age. This is especially important for women at risk for chronic illness after a pregnancy complication like GDM. Efforts should be multifocal to address patient, provider and systems barriers — in other words, “out-of-the box” solutions — solutions that build upon and leverage different kinds of expertise and perspectives.

      We know that new mothers are likely busy with their newborns and, for many reasons, may not be able to focus on their own health, even for an important issue like diabetes prevention. Clinicians, too, are concentrating on immediate concerns (e.g., healing after episiotomy or cesarean section delivery), and find it hard to prioritize prevention. Can innovative solutions and opportunities help both mothers and clinicians close this gap?  

      Pointing the way to solutions

      Our team, energized by these findings from OptumLabs data, has begun to gather a network of researchers, clinicians, patients and their advocacy organizations, health care systems designers, policy makers and communication specialists who are committed to building a better path to high-quality, coordinated and easy-to-access health care for women. We have called this effort: Bridging the Chasm between Pregnancy and Women’s Health over the Life Course. In a working conference in July 2018, invited participants from these different sectors will share their knowledge about missed opportunities to prevent downstream chronic illness after GDM and other pregnancy complications, generate ideas for potential solutions, define priorities together and issue a joint strategic plan for research and action.

      Strategies that emerge from this process may include, for example:

      • Streamlining referral systems to bridge the gap between obstetrics and primary care
      • Bringing services directly to mothers after delivery through home glucose testing visits or technology-enabled virtual primary care visits
      • Expanding the role of doulas and patient navigators to assist with follow-up testing and appointments
      • Strengthening the likelihood of contact with primary care early in a woman’s life, to establish a foundation of regular preventive care that she can return to after delivery.

      This effort, supported by grants from NIH-NIDDK, the Office of Women’s Health Research at NIH, and the Patient-Centered Outcomes Research Institute (PCORI), will field a website for sharing information, publish conference proceedings, issue a formal strategic plan and engender a new round of collaborative research and programmatic activities. Stay tuned for more on the outcomes of this network.

    • Translating Shades of Gray: How can we accelerate value in health care?

      Published Apr 04 2018, 1:35 PM
      • Health care
      • Value
      • AARP

      By Margot Walthall, MHA, and Darshak Sanghavi, MD, OptumLabs

      Change is hard, particularly as our country focuses more on value — not volume — in health care.

      Getting paid based on number of tests or procedures has led to over-treating patients, exposing them to unnecessary health complications and higher costs. By focusing instead on the most effective treatments based on research, we can deliver the highest quality care, while saving money for the health system — and for patients.

      We know some medical tests and procedures are more harmful than helpful for certain patients. They may create additional health risks, cost a lot, have unpleasant side effects and, in some instances, lead to a cascade of unnecessary or unsafe follow-on services.

      These “low-value” medical services are more common than you might realize. With the input of more than 70 medical specialty societies, the Choosing Wisely campaign has identified hundreds of low-value services (LVS) to help improve care decisions between providers and patients

      For instance, we think of cancer screenings as generally useful preventive measures (the sooner you catch something, the better) that saves many lives. However, these experts found that colonoscopies for patients older than 75 can be more harmful than helpful. In these patients, colonoscopies can put them at risk for intestinal tears, dehydration and fainting. Combine this fact with additional out-of-pocket costs, time and stress associated with the screening and ask: Are these tests worth the costs if the patient does not have specific risk factors for colon cancer?

      It can be challenging to reconcile population-based recommendations when treating an individual person. Moreover, our research with AARP reveals that reducing the use of some of these LVS is easier said than done. This suggests that while our health care system has made some progress in transitioning to high value tests and procedures, we have a long way to go.

      Some low value services are easier to reduce than others

      The appropriate use of health care services is an important issue for AARP, OptumLabs’ founding consumer advocate partner, and its nearly 38 million members. We wanted to see whether efforts to reduce low value services were having an impact on the health system

      Using de-identified OptumLabs claims data, researchers from AARP and OptumLabs analyzed trends in use of 16 low-value services from 2009, before the creation of Choosing Wisely, to 2014 among adults ages 50-plus with commercial insurance and adults ages 65-plus with Medicare Advantage.

      Overall, we found that since the Choosing Wisely campaign and other efforts to increase value in health care began, there continues to be a lot of variation — clear successes and additional opportunities — in the use of specific LVS.

      Here are some examples.

      Declines in chest x-rays before surgery

      For decades, it’s been common for doctors to routinely give patients chest x-rays before surgery as a safety measure. Because these x-rays expose patients to radiation, can cause many false alarms and cost extra money, Choosing Wisely recommends that only patients with relevant risks should get them, such as those who:

      • Have signs or symptoms of a heart or lung condition
      • Have heart or lung disease
      • Are over 70 years old and haven’t had a chest X-ray within the last six months
      • Are having surgery on the heart, lungs or any other part of the chest.

      Based on our research, it appears many doctors have gotten the message and researchers found chest x-rays before surgery have fallen considerably across all populations over the six years.

      Figure 1. Pre-operative chest x-ray, 2009-2014

      Line graph shows steep declines in pre-op chest x-rays across all commercial and MA enrollees.
      From 2009-2014, pre-operative chest x-rays declined at the following rates: By 26.8% among commercial enrollees aged 50-64 (COM 50-64), by 21.3% among commercial enrollees aged 65+ (COM 65+), and by 13.1% among Medicare Advantage enrollees aged 65+ (MA 65+).

       

      Declines in cervical cancer screening for women over 65

      According to American Cancer Society Guidelines, women over 65 who have had regular pap smears over the past 10 years should not be screened for cervical cancer unless they have a serious cervical pre-cancer. This recommendation is because the risk of cancer is low at those ages and the testing can lead to unnecessary treatments.

      Reassuringly, researchers found a substantial decline in cervical cancer screening for women over 65 who had commercial insurance. Initially, the rates of over-testing were markedly higher in the Medicare Advantage subgroup compared to commercial enrollees, but over time, that gap has dramatically improved.

      Figure 2. Cervical cancer screening, 2009-2014

      Line graph shows steep decline starting in 2011 for cervical cancer screening among women over 65.
      From 2009-2014, cervical cancer screening in women over 65 declined by 45.2% for commercial enrollees (COM >65) and by 34.5% for Medicare Advantage enrollees over 65 (MA >65).

       

      Little reduction in MRIs for low back pain

      Use of MRI to help diagnose low back pain, one of the most common conditions among adults, had a much more subtle decline. A recent Health Affairs study showed similar findings. Why is this type of imaging more difficult to reduce, despite evidence that many patients with uncomplicated low back pain do not get better faster with imaging?

      Figure 3. MRI for low back pain, 2009-2014

      Line graph shows little change in rates of MRI for low back pain across commercial and MA enrollees.
      From 2009-2014, MRIs for low back pain declined very little for Commercial enrollees age 65+ (1.8%) and Medicare Advantage enrollees aged 65+ (11.4%). MRIs declined slightly more among Commercial enrollees aged 50-64 (20.6%).

       

      To determine if an MRI for low back pain is warranted — and it is in certain situations — doctors need to have careful conversations with their patients about all of their symptoms and health history instead of just ordering the imaging “to be safe.” MRIs are expensive and may be associated with higher rates of unnecessary surgery. But, doctors may not have enough time or may feel pressure from their patient to do the imaging. Therefore, reducing MRI scans in this setting appears to be more challenging.

      How can we accelerate change?

      The results of our work with AARP show that curtailing some low value services is more difficult than others. Awareness alone is not always enough for change. But there are some additional tactics that can help push change. These include reducing barriers to patient-provider conversations, rewarding a de-implementation culture of LVS and encouraging bundles of related — and potentially unnecessary — services for common patient situations.

      Reduce conversation barriers

      Thoughtful provider-patient conversations about which services are recommended, and when, are core to ensuring value in health care. However, a recent survey of providers suggests it has become more difficult to have these discussions with patients. Reasons cited include limited time during office visits, a lack of data to make confident choices, patient insistence and a desire to keep patients happy, as well as malpractice concerns and wanting to do certain things “just to be safe.”

      To solve this, we need to start having broader conversations with patients about what treatments are and are not appropriate so that both doctors and patients feel confident about the choices they make together.

      Create a culture for change

      According to the same provider survey, a cultural change within an organization is required to prioritize the de-implementation of wasteful services as much as the implementation of new treatments. Experts highlight four key actions for organizations to reduce LVS:

      • Ensure leaders prioritize the change.
      • Create a culture of trust, innovation and improvement.
      • Establish a shared purpose and language.
      • Commit resources to the measurement of value.

      Take it to the bundle

      Financial incentives have been blamed for a lot of overuse. Under fee-for-service models, the more doctors treat, the more they are paid. Some bundled payment models that focus on a collection of services rather than individual services have been shown to motivate higher quality health care at lower cost. For example, a possible “Low back pain service bundle” could offer the opportunity to address the overuse of imaging, opioids, surgeries and more. This could lead to fewer MRI scans that result in unnecessary surgery, yielding lower costs and better care.

      As a society, we’ve accepted the fact that many patients receive low value medical services, which continues to take its toll on the health care in America. To move forward in studying and translating what works for de-implementation, we have to focus on better methods that measure clinically meaningful outcomes and unintended consequences for patients.

    • Using new data to personalize stroke prevention

      By Peter Noseworthy, MD, with Xiaoxi Yao, PhD, Mayo Clinic

      The irregular heartbeat known as atrial fibrillation (AF) is a common and serious heart disease impacting about 3 million Americans today. Patients with AF experience palpitations, shortness of breath and dizziness, which can make simple activities such as playing with grandchildren or walking upstairs challenging. They also face a five-fold higher than average risk of stroke, a complication many fear more than death. Fortunately a class of drugs called anticoagulants, or ‘blood thinners,’ can help prevent stroke.

      For 50 years, the only blood thinning drug option had been warfarin, which can be a cumbersome treatment because it interacts with certain foods and requires frequent blood testing to measure its effect on blood clotting. But over the past decade, new non-vitamin K antagonist oral anticoagulants (NOACs) have emerged. Based on the results of highly controlled clinical trials, NOACs are at least as effective as warfarin in stopping strokes. Importantly for patients, these drugs are more convenient to take. Blood testing is not required and there may be fewer problems with ingesting various food and drugs.

      Figure 1. Timeline of oral anticoagulant medication options

      Since 1954, Warfarin was the only oral anticoagulant until the first NOAC was FDA approved in 2010.

      Does that mean that we are free to prescribe these new treatments to all our patients with AF? Not so fast. While NOACs may provide patients with a better quality of life, important questions remain on getting the right treatment to the right patient. That’s where Mayo Clinic’s work with OptumLabs comes into the picture.

      As a cardiologist, I try to help my patients control their symptoms and avoid stroke so that they can enjoy long and fulfilling lives. Now, with at least five different anticoagulant drugs options, as well as several devices and procedures available, choosing the right treatment for an individual patient can be difficult. Increasing this difficulty is that none of the major clinical trials compared each new NOAC drug option to one another, and many of my patients are different than those who participated in the clinical trials.

      Fortunately, the data collected by OptumLabs from routine clinical encounters have helped us answer many of these questions that can help millions of people with AF.

      Comparing new drugs in the OptumLabs Data Warehouse

      Over the past five years, my colleague Dr. Xiaoxi Yao and I have used the OptumLabs Data Warehouse, a curated data set that includes de-identified claims data from more than 125 million commercial and Medicare Advantage beneficiaries of diverse ages and races across the U.S., to publish nearly 30 papers on the topic. We’ve studied three critical anticoagulation areas: effectiveness and safety, appropriate dosing and kidney damage over time.

      Effectiveness and safety

      Past clinical trials showed that NOACs generally prevent stroke as effectively as warfarin, but they do not compare each type of NOAC drug to one another in terms of stroke prevention and other possible side effects. In our study published in CHEST, we looked at medical claims data from October 2010 to February 2015 and compared stroke and bleeding episodes among three groups of patients with AF based on the NOAC that they took.

      It turned out the three drugs are pretty similar for preventing stroke, but have different safety profiles when it comes to bleeding risk. Apixaban users had the least major bleeding, for example, while rivaroxaban users had the most major bleeding.

      Figure 2. NOAC head-to-head comparison for major bleeding risk

      This forest plot shows the major bleeding hazard ratio for each pairwise drug comparison
      This pairwise comparison helps us see which of the three NOACs are safest for avoiding major bleeding side effects: Apixaban is safer when compared to either dabigatran or rivaroxaban; dabigatran is safer when compared to rivaroxaban.

       

      Appropriate dosing

      NOACs have to be dosed very carefully. If the dose is too high, then patients could have unexpected bleeding, and if the dose if too low, they may develop blood clots and be at risk for a stroke. A key to giving a patient the right dose is first to know how well their kidneys work. This is important since some patients with kidney damage, which can be common in people with AF, may need much lower doses than patients without kidney damage because they have an increased risk for bleeding. To see if doctors were properly giving a lower dose to people with kidney problems, we looked at 14,865 patients with AF from October 2010 to September 2015.

      In our report published in the Journal of the American College of Cardiology (JACC), we found almost 1 in 5 patients overall weren’t taking the right dose. This means many patients received a dose that was potentially too high, putting them at risk of bleeding, or potentially too low, increasing the risk of a stroke.

      Figure 3. Prevalence of inappropriate NOAC dosing

      Sixteen percent of patients with AF who take a NOAC are not getting the right dose ― 4% are over-dosed (have kidney damage that warrants a lower dose, but got a standard dose) and 12% are under-dosed (no kidney damage that warrants a lower dose, yet got a lower-than-standard dose).

       

      Kidney damage over time

      Even when dosed properly, researchers have noticed that warfarin and NOACs may gradually harm kidneys over time. In addition to stroke and bleeding risk, kidney damage itself is an important outcome to understand in patients taking anticoagulants. Published in JACC, another one of our studies looked at this in 9,769 patients with AF between October 2010 and April 2016.

      We found that within two years of being on an oral anticoagulant, kidney damage was fairly common. NOACs as a group, however, were associated with less kidney damage than warfarin.

      Figure 4. Kidney safety and outcomes associated with various oral anticoagulants

      Using warfarin as a reference, when the risks of four different kidney functions ― decline in eGFR, acute kidney injury, doubling of creatinine, kidney failure ― are broken down for each NOAC, dabigatran and rivaroxaban have more favorable outcomes than apixaban.
       

      Putting the story together for patients

      Keeping all of this in mind when prescribing anticoagulants for patients can be hard. So our team is working on a decision tool that considers the data from our research, as well as the research of others, to help doctors choose the safest, and most effective treatment plan for our patients.

      Here’s an example of how our learnings can support appropriate anticoagulation choice for two very different hypothetical patients. 

      Sheryl is 65 years old and healthy despite her AF. She runs a small business that requires frequent travel. She is at low risk for bleeding, and has healthy kidneys. She is worried about the dietary restrictions with warfarin, as well as the challenge of monitoring her blood clotting while she is travelling. She opted to take apixaban because the convenience and favorable bleeding risk are worth the additional out-of-pocket expense.

      Maurice is 80 years old, and along with his AF has severe kidney disease, diabetes and hypertension. He has been on warfarin without any major complications since his AF diagnosis seven years ago. For him, the added expense of switching to one of the newer drugs did not seem warranted since he has done well with warfarin and is comfortable
      with this familiar treatment.

       

      By combining large “real world” data sets with the information we’ve gained from clinical trials, I believe we are several steps closer to being able to precisely identify the right treatment for each individual patient.

    • Advancing the use of real-world data to help speed treatments to patients

      By William Crown, PhD, OptumLabs

      For more than 20 years, I used medical claims data to compare the effects of medications on patient outcomes and cost. In the back of my mind (and sometimes the front) I was always worried about what I might be missing since claims data contained limited clinical information. For example, I knew that it would be helpful to know the body mass index, cholesterol levels and blood pressure of patients when studying heart failure drugs. And, when studying breast cancer treatment, it would be critical to control for cancer stage. But none of this information was available in claims data alone.

      This changed in 2009 with the HiTECH Act, which mandated meaningful use of electronic medical record (EMR) data for health care providers. The HiTECH Act transformed the data landscape almost overnight by making it possible to broaden our view into patient care and outcomes by linking patient-level EMR and claims data.

      My previous concerns about possibly missing something important turned to curiosity: Could using real-world data such as linked patient claims and EMR records simulate a randomized controlled trial (RCT)? Could important evidence be produced in months, rather than years, to dramatically cut development costs and accelerate patient access to effective therapies?

      OptumLabs is working to answer these questions.

      What’s so great about randomized controlled trials?

      Randomized controlled trials (RCTs) are used to obtain FDA approval to manufacture and sell a new drug. By randomly assigning patients to treatment and comparator groups, RCTs minimize bias from missing control variables. Randomization also reduces bias intentionally or unintentionally introduced by the investigator or sponsor in the study. 

      While these trials use strict research protocols to help ensure the collection of high quality data, their idealized environment often doesn’t reflect reality. For example, people do not always take their medication as prescribed for a variety of reasons. Data shows that people with chronic conditions like diabetes, hyperlipidemia, or hypertension don't take their medication 25-50 percent of the time.From the perspective of medication adherence alone, the very features of the research protocol that help to strengthen the internal validity of RCT results also may limit their generalizability to the real world.

      The times, they are changing

      Recent FDA regulatory mandates acknowledge this limitation of RCTs and a growing interest in using real-world evidence (RWE) — or, the output of research using real-world data — for approving new uses of an already approved drug and monitoring data to protect patient safety. Reauthorization of the Prescription Drug User Fee Act (PDUFA VI2) and the 21st Century Cures Act3 now require that the FDA

      • Conduct a public workshop on regulatory uses of RWE by the end of FY 2018
      • Fund a pilot and set methodology for RWE by the end of FY 2019
      • Publish draft guidance by end of FY 2021

      Researchers have already been generating RWE via claims analyses to gather safety data on approved products (e.g., FDA's Sentinel Initiative).This has helped establish research designs and methodologies for balancing comparator treatments across large numbers of observed attributes in the data. As a result, well-designed studies utilizing RWE are beginning to look more and more like trusted RCTs.

      Our ability today to link multiple sources of real-world data can help strengthen RWE further. For example, at OptumLabs, we’re combining claims and clinical data. The EMR will tell us when the physician writes a prescription for a medication. But how do we know if the prescription was actually filled? That information is in claims data, not the clinical data. Details about how the patient responded to that medication, however, may only be found in clinical notes. It takes both pieces to see the whole picture, and linking these two sources helps remove biases that would arise from using either type of data alone.

      It’s an observational study — what could possibly go wrong?

      There are contradictory findings when it comes to the reliability of RWE. A recent Cochrane Review concluded that observational studies generally have similar findings as RCTs in the same disease states.But substantial literature also shows wide variation in results from database studies within the same therapeutic areas.

      There are cases when an observational study and RCT may have very different initial results, but reach similar conclusions once the observational study design is adjusted to match that RCT. For example, the observational Nurses' Health Study showed that hormone replacement therapy (HRT) reduced the risk of heart disease among post-menopausal women.A decade later, results from a large RCT, the Women's Health Initiative, found the exact opposite.8

      These seemingly different conclusions created huge anxiety among post-menopausal women being treated with HRT, as well as their physicians. However, it turns out that the difference in conclusions was not due to randomization at all. Rather, the risk of heart disease was highest in a two-year window after starting HRT and then declined over time. When the observational Nurses Health data was re-analyzed to control for this, the results were the same as the Women’s Health Initiative RCT.

      The bottom line is that sometimes observational studies have been able to replicate the results of RCTs and sometimes not. To increase our confidence in the findings from observational studies, we need to understand why this is the case. 

      How can we raise confidence in appropriate use of observational studies?

      OptumLabs is partnering with the Multiregional Clinical Trials Center at Brigham and Women’s hospital to explore this question. Observational Patient Evidence for Regulatory Science And uNderstanding Disease (OPERAND) is a collaboration of stakeholders from industry, academia and regulation to consider the principles behind, the methodology to draw upon, and the appropriate use of observational data in regulatory review and approval. We can then use these design elements to examine the circumstances under which real-world data — specifically, linked claims and EMR data — can be used to confirm previously published RCTs. 

      While individual RCTs have been replicated using observational database analyses before, we plan to replicate a large number of trials across several different therapeutic areas simultaneously (a novel feat). Our findings will complement the efforts of groups like Duke Margolis Center working on the FDA regulatory policy guidelines for RWE. Moreover,  the ability to trust policy evaluations of benefit design, care organizational models, disease management programs or non-drug medical interventions all rest on the same principles being explored in OPERAND.

      There will always be a place for RCTs in areas such as initial drug approvals. But with the vast amounts of high-quality data available to us today, we have a unique opportunity to explore how we can use this data to generate reliable RWE more quickly and at less cost — ultimately benefiting patients by accelerating access to effective treatments.

      Among the myriad of challenges around the U.S. opioid epidemic is the lack of consistent, data-driven ways for the health system to measure and respond to it. That’s why OptumLabs collaborated with a panel of national clinical and public health experts to develop a comprehensive framework of 29 claims-based measures that are organized by four opioid-related domains: prevention, pain management, opioid use disorder treatment, and maternal and child health. These metrics have been shared with diverse stakeholders in various forms, and have garnered significant interest for their potential to guide a more holistic approach to evaluating and improving efforts to tackle this public health crisis. We are excited to share them with you! – Editor

      This following piece first appeared in the Health Affairs Blog on December 18, 2017.

      The annual rate of opioid-related deaths in the United States will surpass the historic peak annual death rates from motor vehicle accidents, HIV infections, and firearms to become the leading cause of death for people less than 50 years of age. The National Vital Statistics System reported roughly 64,000 deaths from drug overdoses in 2016 and year-to-year relative rate increases of more than 20 percent. Responding to this epidemic with such dramatic increases, the Department of Health and Human Services declared the national opioid crisis a public health emergency on October 26, in conjunction with President Donald Trump’s pronouncement on the same day.

      The current opioid crisis came after substantial increases in per-capita frequency and dosages of prescription opioids beginning in the late-1990s. Researchers hypothesize the increases were driven in part by efforts to recognize pain as the fifth vital sign as codified by the Joint Commission in 2001, pharmaceutical marketing practices, and lack of recognition of the risks of dependence and addiction with prolonged use. According to the Centers for Disease Control and Prevention (CDC), when averaged nationally, roughly one prescription for opioids is written for every person in the United States annually.

      Current gaps and opportunities in quality metrics

      The epidemic nature of the opioid crisis and its immense complexity has exposed important gaps in the ability of the health care system to respond in a data-driven manner. Typically, federally-endorsed performance measures are developed to track and address key health care processes or outcomes targeted for improvement using blunt payment incentives, which understandably require a high degree of evidence and testing prior to widespread deployment. The development process is not typically geared to rapid-cycle quality improvement programs, which can be deployed via education, quality improvement, comparison reporting, and value-based payment incentives as has been demonstrated in the private sector. As a result, formal federal measure development has not kept pace with the rapid cadence of the opioid epidemic.

      For example, the Pharmacy Quality Alliance developed three opioid misuse measures in 2015 (targeted towards identifying high frequency/dosage prescribers or towards “doctor-shopping” patients) and these measures did not complete the endorsement process of the National Quality Forum (NQF) until 2017. Broad adoption by federal payment programs may take several more years, during which time contributing prescribing trends could continue. Over a year ago, the CDC released guidelines on the appropriate dosing of opioids for pain, and the former U.S. Surgeon General mailed a letter to 2.3 million clinicians on the same topic, but no endorsed quality measure to assist with this recommendation has been made widely available.

      The need for a comprehensive quality measurement framework examining the impact of the epidemic from many vantage points has particular timeliness, as the White House opioid commission recently recommended that the nation "invest only in those programs that achieve quantifiable goals and metrics."

      OptumLabs, a collaborative research and innovation center, embarked on a five-month program to develop a comprehensive framework of 29 claims-based measures for the opioid crisis. The measure set for this program benefitted from the input of a panel of national clinical and public health experts, including representatives from the CDC and the Substance Abuse and Mental Health Services Administration. Four key domains for the metrics were identified: prevention, appropriate acute and chronic pain treatment, Opioid Use Disorder (OUD) treatment, and maternal/child health. Where possible, measures were abstracted from publically available specifications which were refined as needed by expert coding teams. The measures were calculated using the OptumLabs Data Warehouse, which includes de-identified integrated pharmacy, medical claims, and enrollment data from a geographically diverse population of approximately 150 million United States residents currently or previously enrolled in commercial and Medicare Advantage programs. The measures are described in Exhibit 1 and technical specifications are described in a supplemental index.

      Results of comprehensive framework development

      Related to the prevention rubric of Exhibit 1, data from 2016 shows that the rate of compliance with CDC-recommended prescribing for a first opioid fill was approximately 55% and the rates of new opioid fills was 122 per 1,000 enrollees. To better explore the distribution, the measures were computed at the county level and found to be nearly normally distributed (See Exhibit 2), with substantial and meaningful variation, suggesting that local factors may strongly impact prescribing volume and guideline-adherence. (Similar variation was seen among several measures; data not shown.)

      In 2016, the year the CDC issued guidance for prescribing, there was striking geographic variation (See Exhibit 3) in appropriate prescribing with further variation in the specific component of guideline non-adherence. In some areas physicians tended to prescribe high doses for new prescriptions, while in other areas, they prescribed for longer durations suggesting the need for tailored interventions based on location. For example, in Massachusetts, there was overall average performance in the composite measure of CDC-compliant prescribing when compared with national benchmarks, and the opportunity for improvement appears to relate to excessive opioid dosage, rather than prescription duration (See Exhibit 4).

      Encouragingly, in the pain rubric of Exhibit 1, post-operative pain appeared to be well-managed with 95 percent avoiding emergency department visits resulting in receipt of new opioids. Our claims based measures related to patients on chronic opioids showed moderate utilization of non-opioid drug treatment by these patients with about 45 percent receiving this treatment, and low use of non-drug treatments (roughly one in four patients). It should be noted that patients may be accessing some of these therapies outside the benefits of their current health insurance plans.

      In the treatment rubric of Exhibit 1, rates of medication-assisted treatment (MAT) for OUD were approximately 28%, with a particular opportunity in those following overdose where rates of MAT were 11%. This is consistent with reported national trends. Additional data from our analysis suggests the relative prevalence of OUD increased 50 percent over the 2014-2016 time period, potentially due to both higher incidence and improved coding with ICD-10 adoption.  

      Moving forward with comprehensive framework

      While traditionally developed performance metrics are essential, their value in managing acute crises is limited by an extended ratification process, a focus on one measure at a time, and delayed provider feedback. By offering a comprehensive diagnostic snapshot with benchmarked data on populations that can be attributed based on patients’ geography, payer, or provider, “just in time” comprehensive quality frameworks can enable public health agencies, integrated health care providers, and/or health plans to more rapidly benchmark their status and deploy and evaluate the impact of interventions.

      Within our larger organization, for example, initiatives for safer prescribing via pharmacy benefit management, access to MAT via expanded provider networks, clinical and consumer education programs, and dozens of other programs are being pursued in various populations and geographic regions, and such a framework could help assess outcomes over time. To take one example, first-fill drug utilization rules were placed in effect in July 2017 by several hundred clients served by our organization, and within two months of implementation, initial review found relative reductions of 82 percent in excessive dosage and 65 percent reduction in excessive duration of new opioid prescriptions relative to CDC opioid best practice prescribing guidelines among this cohort. In this manner, “just in time” frameworks may permit a precision-medicine approach to the opioid epidemic based on a common set of data-driven metrics.

    • Risk in perspective: A rare heart surgery infection explained with data

      Rondi remembers the day she got the letter in the mail from her hospital in central Massachusetts. It was addressed to her, but was about her teenaged son, Cole, who was born with a heart defect and underwent cardiac surgery a few months earlier. Like Rondi, thousands of other patients and families across the country were opening similar letters from their doctors in the fall of 2015.


      We are notifying patients who have had open-heart surgery, about a potential infection risk related to this surgery. We are contacting you today, as you or a member of your family have been identified in clinical records as a patient who might be affected...


      Rondi had many questions.

      “It was definitely nerve-racking,” said Rondi. “I was glad to know about the issue but my biggest concern was: How bad is it? Is this letter telling me everything?”

      Rondi was just one of thousands of people who received this letter because of a spike in reported infections connected to a device used in heart surgeries. But should Rondi have been concerned? Was there a real imminent threat to her son’s health? 

      In this blog post, we will look at how data can provide important context on health risks, assisting us in determining when and how to communicate to patients. 

      A rare bacterial infection sourced from a commonly used device

      The risk of infection was linked to bacteria that contaminated heater-cooler devices used during open chest surgeries. According to tests, contamination may have occurred during manufacturing of the equipment. More than 250,000 heart bypass procedures are performed each year in the U.S. with the help of these heater-cooler devices that regulate body temperatures. This could have been a major public health crisis.

      Graphic representation of heater-cooler circuits tested for transmission of mycobacterium chimaera.

      The suspect was a type of bacteria known as nontuberculous mycobacterium (NTM). While most people exposed to these bacteria never get an infection, a spike in reports of infections in patients linked to contaminated heater-cooler devices concerned public health officials at the Centers for Disease Control and Prevention (CDC). They asked providers to inform patients of the infection risk, which resulted in the letter Rondi received.

      “The letter explained that the signs of an infection could take several months or years to show. And the list of potential symptoms was very broad, such as night sweats, muscle aches, weight loss, fatigue and unexplained fever,” said Rondi. “I was most nervous to tell Cole about the letter without more information. It wasn’t until we spoke with our cardiologist and he clearly explained the small risk and how it relates to my son specifically, that we felt more at ease.”

      Based on a few published studies, the CDC estimated that the risk of a patient getting an infection was between about 1 in 100 and 1 in 1,000. This is a large range, which can be stressful for patients when the risks are not put into proper perspective.

      We asked ourselves whether it was possible to find a more precise estimate of risk. Knowing the precise risk could better inform public health communications and keep families like Rondi’s at ease in the event of future outbreaks.

      To answer this question, OptumLabs queried our data set of commercial and Medicare Advantage claims for more than 127 million people over 20 years.

      Demonstrating real-world risks with real-world data

      We explored the risk of mycobacterial infection among a group of patients who had claims for open heart bypass surgery between July 1, 2007 and June 30, 2015 and compared it to the risk of infection among patients who had claims for angioplasty —  a non-open heart cardiac procedure that does not involve a heater-cooler device — during the same time period. Both groups of patients had very similar health conditions. Because the only major difference between them was the type of surgery they had, we were able to isolate the impact of the heater-cooler device used in open heart surgery. Infection was defined by looking at ICD-9 diagnosis codes for treatment with rifabutin, a common antibiotic used to fight the infection.

      Looking at patients enrolled in the health plan for four years in a row, the small rate of infection among patients who had bypass surgery with a heater-cooler device was not statistically higher than the rate of infection among patients who had angioplasty without a heater-cooler device. In short, it appears that the actual risks to patients were quite low.

      Chart showing difference in risk between those with or without bypass surgery is not significant

      This initial analysis isn't definitive by any means, but shows how health care data can help point us in the right direction to guide patients, and support doctors when communicating the risks of one treatment or procedure over another to patients. 

      Looking at these results, should a letter have been sent to Rondi? We would argue that the letter should have been written with more precision, informed by data, and ready to answer patients’ second and third questions. Ideally, patient communications should provide relevant information that can help them put complicated risks into perspective. It can reduce confusion and prevent unnecessary worry.

      When it comes to our health or the health of a loved one, it’s often the questions left unanswered that can cause more distress than even the worst news. With the help of data, we can work to get the right answers to the right people to guide important real world decisions and positive outcomes.

    • Making diabetes care personal with the right data

      It isn’t easy being the pancreas.

      Nobody understands this better than somebody with diabetes — a chronic disease impacting more than 30 million people in the United States, according to the Centers for Disease Control and Prevention. A healthy pancreas constantly checks the body’s blood glucose (sugar) levels and adjusts them from rising too high by releasing tiny bursts of insulin. In people with type 2 diabetes, the body resists that insulin and in time the pancreas cannot keep up with the demand. When glucose in the blood becomes dangerously high, it can cause damage to vital organs like the kidneys, heart, eyes, and brain over many years. That’s a lot of pressure!

      When the pancreas struggles, doctors can step in to monitor a patient’s average glucose levels through a blood test called hemoglobin A1C (HbA1c). For most people with controlled type 2 diabetes, it’s recommended they’re tested 1–2 times per year.

      But it turns out there’s a lot of variation when it comes to how often patients are getting their A1C tested. Some are tested more frequently than necessary. Others are not tested enough. OptumLabs® and our partners are leveraging data to help us to gain insights on how this may impact a patient’s health, and how to better manage their diabetes.

      Your zip code could impact how often you’re tested for diabetes

      Image of U.S. map showing percentage of Medicare enrollees aged 65-75 with diabetes getting recommended yearly test of hemoglobin A1C. States such as Minnesota, Wisconsin, Iowa and Virginia have the highest percentage, while states such as Indiana, West Virginia and Louisiana have the lowest percentage.

       

      This map from Dartmouth researchers shows the striking variations in the proportion of Medicare beneficiaries getting the recommended yearly A1C testing.

      There are large areas of the country where roughly 1 in 4 patients don’t get their A1C monitored once a year. If left untreated, poor blood glucose control can cause serious complications down the line, like kidney failure or blindness.

      Understanding the variation in appropriate blood glucose level testing has led government health care programs and others to emphasize proper monitoring and comprehensive diabetes care through special measures. Today, insurance companies are graded — and rewarded — by Medicare on their performance with several diabetes measures. One such measure is keeping the A1C level for patients with type 2 diabetes under 8 percent. Low A1C levels mean the average blood sugar isn't too high — which is a good thing to a certain extent.

      Guidelines may improve care, but sometimes there are unintended consequences

      Higher quality care is everybody’s goal and driving accountability for better quality makes sense to most people. But what happens when providers focus on following these guidelines to test at least once a year and keep A1C levels low? Is it possible that a well-intentioned guideline could have some unanticipated side effects? Endocrinologist Dr. Rozalina McCoy, MD, and her research team at Mayo Clinic (OptumLabs’ co-founding partner) recently investigated this question and found some surprising trends.

      Using OptumLabs data, the Mayo team found1 that patients with controlled type 2 diabetes were being tested much more frequently than 1–2 times per year. More than half of patients were getting their A1C checked 3–4 times per year, and 6 percent of patients were getting 5 or more tests per year.

      When doctors test more often, they have more information about a patient’s glucose levels. This information could lead to better care, but there’s also potential this may do more harm than good.Illustration of five human figures, one is orange and the other are gray. This shows that 1 in 5 patients with controlled type 2 diabetes were likely over treated with glucose-lowering drugs.

      In a follow-up study, the Mayo team discovered2 that more than 1 in 5 patients with controlled type 2 diabetes were likely being over treated with glucose-lowering drugs, almost doubling their risk of dangerously low blood sugar episodes (“hypoglycemia”). These are severe episodes that can land patients in an emergency room or hospital.

      Making medical care better is a learning process. When a problem comes to light, like inconsistent A1C testing, the system responds to correct the problem by creating measures and incentives. However, unexpected side effects can emerge like over-testing that leads to over-treatment. What should we do to fix this unintended consequence?

       

      Learning from research to improve quality measures

      Upon reflection, the root of this issue is that the diabetes care measure only rewards lowering A1C levels. In collaboration with our founding consumer advocate partner AARP, OptumLabs established a new research project with Mayo Clinic to create a more nuanced performance measure that takes a “Goldilocks approach” to diabetes management.

      Rather than just shooting for a low A1C, a new measure will seek to reward being “in the sweet spot” of “just right” care, so the A1C should be neither too high nor too low.

      Safe range Target regimens depend on clinical complexity, number and type of glucose-lowering medications prescribed, and other patient risk factors.
      Too high ≤ 1 medication High-intensity medication treatment

       

      The actual measure has multiple subcategories to address the nuanced approach required to tailor treatment for patients in different Hba1C ranges with unique risk profiles.

      Mayo Clinic partners will prototype the measure using millions of de-identified patient records available from OptumLabs, and if successful, work to share this knowledge more widely with nationally recognized health organizations such as the National Quality Forum, which OptumLabs has collaborated with3 in the past.

      This is the blessing and the curse in the age of big data: Doctors can get a lot of helpful information to guide treatment, but the data flow can also be overwhelming. A key challenge for researchers, like those at OptumLabs, is shaping how to use the right signals to improve and not complicate treatment.

      It certainly isn't easy being the pancreas, which continuously evaluates and modifies its testing and output to manage someone's blood sugar. No one can reproduce its working perfectly. But the overall example it sets — always observing, testing, responding, correcting and having a big impact on the overall system — is one that OptumLabs and our partners strive to emulate.
