A study last summer in the journal JAMA Network Open, for example, found that people who saw their doctor for acute pain later in the workday were more likely than those with morning appointments to get a prescription for opioid painkillers — a class of medications with potentially life-threatening side effects. Another recent study suggests that patients seen later in the day are less likely to receive recommended cancer screening tests, like mammograms.
