In 1950, doctors in practice could expect the total amount of medical knowledge to double every 50 years. By 2020, it will take just 73 days. How’s a young doctor supposed to keep up while managing the hectic pace of practice?
In residency, I was surrounded by educational opportunities. With lectures, grand rounds, and most importantly, a deeply skeptical cohort of residents who questioned anything and everything they were told to do, it was hard to not stay up to date. Now, as I start my practice in primary care, I find myself unsure how to best tackle the ever-growing field of medical knowledge. I decided to phone a friend for advice.
Dr. Rachel Stark is the associate director of the internal medicine residency program at Cambridge Health Alliance, and has been in practice for twelve years. Between her roles as an administrator, educator, and physician, she manages to engage with the ever-changing state of medical knowledge. We sat down in her office to discuss how she keeps up.
Ask the Right Questions
The first step to remaining current, Dr. Stark said, is to retain a sense of curiosity about even the “mundane, everyday work” that internists do. Without that sense of curiosity, we stick with diagnostic and treatment algorithms that are flawed or out of date.
“Part of the process of being an internist is being able to identify and articulate a well-reasoned clinical question,” she explained. “Once you do that, you’ll have a much better ability to find an answer.”
For instance, in diagnosing the flu, we often rely on flu swabs. But I noticed a discrepancy between my clinical diagnosis of flu and the swab, which was often negative. With this as a spur, I found that rapid diagnostic tests have a specificity of 90%, sensitivity as low as 42% in clinical practice. Therefore, these tests can be used to rule out, but not rule in, the diagnosis of influenza. I am now much more likely to diagnose flu and to use swabs mostly when I am concerned about institutional outbreaks.
Choose an Environment that Challenges You
In How Doctors Think, Dr. Jerome Groopman dissects the most common cognitive errors in medicine, from diagnostic “anchoring” to “confirmation bias.” With intense time pressures and demands from patients for definitive answers, once we are out of the intense environment of residency we can be tempted to stick with diagnoses and treatments that we are familiar with, and to ignore research that conflicts with what we already know.
As an antidote to this, Dr. Stark’s advice for new doctors is to work in an environment that is “always challenging.” For her, the challenge primarily happens through her role as an educator. “When you’re responsible for your patients but you’re also responsible for a generation of physicians behind you,” you are pushed to practice the best available medicine, she says. For those of us not involved in day-to-day education, we are still working in teams with colleagues who will have different practices that should inspire us to examine our own assumptions. We can also be better team leaders and physicians by encouraging everyone working with us to bring up questions in a non-threatening environment.
Facebook Is a Fun Place to Argue About Science, Too
Social media is not for everyone, and Dr. Stark is not into it “at all.”
Personally, I like Facebook and Twitter for knowing what experts and non-experts are talking about, especially because a link to a research paper is usually included in well-written articles. If I think something is incorrect or misrepresented, I often respond, which starts a conversation with my friends in health care, who may have a different take, and friends outside of health care who have interesting and practical questions. In answering them or sharing information, I practice what I consider to be one of our hardest and most important skills: explaining uncertainty to patients.
Let Others Curate Resources for You
Dr. Stark subscribes to a number of resources that narrow down the vast number of articles published every day to a dozen or so that may be relevant. She pointed to NEJM Journal Watch, and the American College of Physicians’ Journal Club, which she said breaks down “the study design, the number need to treat, the number need to harm,” its quality, and the context of what came before. She also scans the table of contents of The New England Journal of Medicine and the Journal of the American Medical Association and reads articles that are relevant to her practice.
Staying Current Is Our Commitment to Our Patients
Given that medical knowledge is doubling more than once a year, I asked Dr. Stark if it is even possible to stay up to date. She responded that the constant change in medicine is one of the things that makes being a doctor a great privilege. “It can seem daunting,” she said. But we have to make curiosity “the foundation of our care of patients.” This, she concluded, is “our commitment to our patients.”
