When should electronic medical records reminders for cancer screening stop?-Results from a national physician survey

Many older adults are screened for breast and colorectal cancers beyond guideline recommended thresholds. Electronic medical record (EMR) reminders are commonly used to prompt cancer screening. Behavioral economics theory suggests that changing the default settings for these reminders can be effective to reduce over-screening. We examined physician perspectives about acceptable thresholds for stopping EMR cancer screening reminders.

In a national survey of 1200 primary care physicians (PCP) and 600 gynecologists randomly selected from the AMA Masterfile, we asked physicians to choose whether EMR reminders for cancer screening should stop based on a list of criteria that included age, life expectancy, specific serious illnesses, and functional limitations. Physicians could choose multiple responses. PCPs were randomized to questions about breast or colorectal cancer screening.

A total of 592 physicians participated (adjusted response rate 54.1%). 54.6% chose age and 71.8% chose life expectancy as criteria for stopping EMR reminders; only 30.6% chose functional limitations. Regarding age thresholds, 52.4% chose ages ≤75, 42.0% chose a threshold between 75 and 85, 5.6% would not stop reminders even at age 85. Regarding life expectancy thresholds, 32.0% chose ≥10 years, 53.1% chose a threshold between 5 and 9 years, 14.9% would not stop reminders even when life expectancy is <5 years.

We found that many physicians would continue EMR reminders for cancer screening even in light of older age, limited life expectancy, and functional limitations. This may reflect reluctance to stop cancer screening and/or reluctance to stop EMR reminders so that physicians can retain control to decide for individual patients, for example, to assess patient preference and ability to tolerate treatment. There was consensus for stopping EMR reminders at ages 85+ and <5-year life expectancy. Interventions that seek to reduce over-screening by suppressing EMR reminders may be important for these groups but may have limited physician buy-in outside these thresholds.
