A new study suggests that doctors are more likely to skip screenings and otherwise make mistakes with patients later in the day. According to a JAMA Network Open study, doctors ordered fewer breast and colon cancer screenings for patients with an afternoon appointment – despite the fact that all patients were due for a screening. According to the study, the doctor was most likely to order a medical screening for his patient with an 8 AM appointment. By 4 PM, the likelihood that the doctor would order screens for their patient had dropped by 10 to 15 percent.
Other studies have confirmed that poorer outcomes for patients are more likely in the afternoon. A 2014 study, cited by The New York Times, found that doctors were more likely to dole out unnecessary antibiotic prescriptions in the afternoon. In fact, the likelihood of an unnecessary antibiotic is 26 times higher for a 4 PM appointment compared to an 8 AM appointment. Other studies located by the New York Times found that patients were less likely to receive the flu vaccine and more likely to receive prescription opioids for back pain. Even the amount of hand washing by doctors fell during the afternoon hours.
