Deliberate clinical inertia protects patients from low value care

Clinical inertia is usually considered to be a negative term, used to refer to situations in which clinicians do not appropriately initiate or intensify therapy for uncontrolled chronic conditions. For example, a recent study in JAMA Internal Medicine found that less than one-quarter of patients with chronic hypercalcemia in the Veterans Affairs health system received recommended parathyroid hormone level testing, and only about 13 percent of patients who met diagnostic criteria for primary hyperparathyroidism underwent parathyroidectomy.

However, clinical inertia has also been described as a "clinical safeguard" against aggressive consensus guideline prescriptions that do not account for patient preferences and/or potential harms of intensifying treatment. For example, an analysis of the incremental benefits of and harms of the 2017 American College of Cardiology / American Heart Association guideline that redefined hypertension as a sustained blood pressure of >= 130/80 mm Hg concluded:

For most adults newly classified as having high blood pressure under the ACC/AHA guideline (the 80% of those newly diagnosed who have <10% 10-year risk), there is no incremental benefit in CVD risk reduction, but potential incremental harms from disease labeling, and, for those who meet the threshold for drug treatment, from adverse drug effects.

In this instance, a large number of patients with systolic blood pressures between 130 and 140 mm Hg could potentially benefit from clinical inertia by avoiding a hypertension diagnosis, additional testing, or prescription medications.

In a 2011 JAMA commentary, Drs. Dario Giugliano and Katherine Esposito observed that clinical inertia "also may apply to the failure of physicians to stop or reduce therapy no longer needed," but that "this neglected side of clinical inertia does not seem to generate as much concern among physicians or scientific associations." A review of polypharmacy in the July 1 issue of American Family Physician noted that regular use of at least five medications is associated with decreased quality of life, increased mobility problems and falls, greater health system use, and increased long-term care placement. Judicious deprescribing can help reduce polypharmacy and improve patient outcomes.

Another (sometimes better) strategy is not starting nonbeneficial medications for unclear reasons in the first place. In a 2018 article in Emergency Medicine Australasia, Dr. Gerben Keijzers and colleagues defined "deliberate clinical inertia" as "the art of doing nothing as a positive response." Arguing that doctors generally have a bias to intervene with diagnostic tests, drugs, or procedures, they suggested reframing the typical decision-making approach:

In clinical practice, 'risk versus benefit' is usually considered in terms of missing a diagnosis rather than potential risks of treatment, so a better approach to care may be to ask, 'Is this intervention more likely to cause harm than the underlying condition with its possible harm or risk?' There are many reasons why 'doing nothing' is difficult, but doing what we can to provide excellent care while preventing medical harm from unnecessary interventions must become one of the pillars of modern holistic healthcare.

Health professionals may readily grasp the rationales behind campaigns to avoid harms and costs of low value care such as Choosing Wisely and Right Care, but patients may be skeptical. Dr. Keijzers and colleagues suggested several ways to support deliberate clinical inertia in practice: empathy and acknowledgment; symptom management; clinical observation; explanation of the natural course of the condition; managing expectations; and shared decision-making ("communicating rather than doing").

The places in America where doctors won't go

Two years ago, I attended the annual Teaching Prevention conference in Savannah, Georgia. Since I hadn't spent much time in Georgia outside of Savannah and Atlanta, the welcoming plenary on improving health outcomes for the state's rural and underserved populations was eye-opening. According to Dr. Keisha Callins, Chair of the Department of Community Medicine at Mercer University, Georgia ranked 39th out of 50 states in primary care physician supply in 2013 and was projected to be last by 2020. 90% of Georgia's counties are medically underserved. Mercer supports several pipeline programs that actively recruit students from rural areas, expose all students early to rural practice and community health, and provide financial incentives for graduates who choose to work in underserved areas of the state. But it's an uphill battle. Even replicated in many medical schools across the country, these kinds of programs likely won't attract enough doctors to rural areas where they are most needed.

When people talk about places where doctors won't go, they tend to focus on international destinations, such as war zones in Syria or sparsely populated areas of sub-Saharan Africa. It's hard to believe that many places in America are essentially devoid of doctors, and access to medical care is as limited as in countries where average income is a tiny fraction of that in the U.S. Providing health care coverage for everyone, while important, won't automatically ensure the availability of health professionals and resources in rural communities. In a JAMA Forum piece, Dr. Diana Mason discussed the financial struggles of rural hospitals that support community health alongside primary care clinicians, which become more acute when budget cuts to rural health programs and grants occur.

Georgia is hardly the only state struggling to attract doctors to rural communities. In the Harper's Magazine story "Where Health Care Won't Go," Dr. Helen Ouyang chronicled the tuberculosis crisis in the Black Belt, a swath of 17 historically impoverished, predominantly African American counties in rural Alabama and Mississippi. In Marion, Alabama, a single family doctor in his mid-fifties and an overwhelmed county health department grappled daily with the lack of resources to contain the spread of the disease:

There is no hospital in town. The nearest one, twenty minutes away in Greensboro, has minimal resources. The road to get there is narrow, unlit at night, and littered with roadkill. Perry County has only two ambulances, one of which is on standby for the local nursing home. Life expectancy here is seven years lower than the U.S. average, and the percentage of obese adults is almost a third higher; by the latest count, more than a quarter of births take place without adequate prenatal care. [Dr. Shane] Lee’s clinic is Marion’s only place for X-rays.

Ouyang went on to describe the University of Alabama's Rural Health Leaders Pipeline, a program that recruits and trains medical students from rural communities to eventually become primary care physicians for those communities. Although the program has been modestly successful (since 2004, "more than half have gone on to work in rural areas, compared with only 7 percent of their classmates"), many Black Belt counties have yet to benefit from it. Many medical schools use a minimum score cutoff on the Medical College Admission Test (MCAT) that tends to penalize applicants from rural and minority communities, even though those students are more likely to become primary care physicians for underserved populations:

The purpose of doctors, after all, is to tend to patients’ ultimate needs. Increasing the supply of primary care physicians is linked to lower mortality rates; after compiling data from studies across different parts of the country, a group of public health researchers found that by adding one more doctor for every 10,000 people, as many as 160,000 deaths per year could be averted. When the same researchers considered race as a factor, this benefit was found to be four times greater in the African-American population than among white people. Studies have also observed that the availability of primary care significantly reduces health disparities that result from income inequality.

The problem of too few primary care clinicians is not limited to rural America, but those communities are where the need is greatest, since a town without a family doctor is unlikely to have any other types of physicians. Medical schools can't easily change social determinants of health on their own, but they can rewrite their mission statements to emphasize providing health care to everyone regardless of geography, and implement recruitment and admissions policies that actually support that goal.

Population health, colorectal cancer screening, and guideline development

Although a recent vacation and catching up after returning to work have delayed posting to the blog, I wanted to share three of my recent publications in other venues that you might find to be of interest. In my latest Medscape commentary, I added my voice to an ongoing debate about the future role of family physicians in addressing population health and social determinants. Should we expect all family physicians to be "experts in population health," or limit population health training to basic competencies that are generally tied to clinical settings?

My view is that medical schools and residency programs should offer a scope of population health training that falls somewhere in between Dr. DeVoe's aspirational goals and Dr. Campos-Outcalt's minimum objectives, consistent with their institutional mission statements, faculty resources, and existing connections with community organizations. 

For example, over the past several years, my students and family medicine residents have benefited from classroom and experiential learning from faculty in Georgetown's Department of Health Systems Administration, its law school, and its school of public policy. Each year we raise the bar for population health in undergraduate medical education so that our graduates will be able to utilize population health skills in residency and, if desired, incorporate them into their future practices.

Meanwhile, over at American Family Physician, fellow Deputy Editor Mark Ebell, MD, MS and I launched a feature that evaluates new diagnostic tests:

[Diagnostic Tests: What Physicians Need to Know] uses a structured approach to review key test characteristics, including discussions of accuracy, benefits, harms, cost, and cost-effectiveness. It concludes with a clinical bottom line: Is there a role for this test in primary care practice and, if so, for which patients? We aim for this new feature to cut through the “hype” and provide independent, objective assessments of new diagnostic tests that readers are considering incorporating into their practices.

Family physicians and other primary care clinicians who read AFP can find my first piece in the series, mSEPT9 Blood Test (Epi proColon) for Colorectal Cancer Screening, in the July 1 issue of the journal.

Finally, on the AFP Community Blog, I took readers "behind the scenes" of the updated American Academy of Family Physicians (AAFP) clinical practice guideline on depression following acute coronary syndrome events. Those of you who are interested in learning more about how the AAFP develops guidelines can check out some of their background resources, such as a short video series and the detailed Clinical Practice Guideline manual. I am currently working with the AAFP to develop clinical practice guidelines on two common conditions encountered by family physicians.

As Common Sense Family Doctor approaches its 10-year anniversary (July 24, 2019), topics on deck for future posts include artificial intelligence (AI) in primary care, the upside of clinical inertia, and more developments in overdiagnosis. Stay tuned.
