Prescriptions for Antidepressants Increasing among Individuals with no Psychiatric Diagnosis

Americans are no strangers to antidepressants. During the last 20 years the use of antidepressants has grown significantly making them one of the most costly and the third most commonly prescribed class of medications in the U. S. According to the Centers for Disease Control and Prevention, from 2005-2008 nearly 8.9 percent of the U.S. population had at least one prescription in this drug class during any given month. A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health examines national trends in antidepressant prescribing and finds much of this growth was driven by a substantial increase in antidepressant prescriptions by non-psychiatrist providers without any accompanying psychiatric diagnosis. The results are featured in the August 2011 issue of Health Affairs.
“We’ve seen a marked increase in antidepressant use among individuals with no psychiatric diagnosis. Nearly four out of every five antidepressant prescriptions are written by non-psychiatrist providers,” said Ramin Mojtabai, MD, PhD, MPH, lead author of the study and an associate professor with the Bloomberg School’s Department of Mental Health. “Between 1996 and 2007, the number of visits where individuals were prescribed antidepressants with no psychiatric diagnoses increased from 59.5 percent to 72.7 percent and the share of providers who prescribed antidepressants without a concurrent psychiatric diagnosis increased from 30 percent of all non-psychiatrist physicians in 1996 to 55.4 percent in 2007.”
Using data from the 1996-2007 National Ambulatory Medical Care Surveys, researchers reviewed a national sample of office-based physician visits by patients ages 18 years and older during a one-week period. They conducted two sets of logistic regression analyses, comparing antidepressant visits lacking psychiatric diagnoses with antidepressant visits including psychiatric diagnoses and visits lacking both prescriptions for antidepressants and psychiatric diagnoses. In addition, Mojtabai and colleagues assessed physician practice-level trends in antidepressant visits without psychiatric diagnosis and found that in the general medicine practice, antidepressant use was concentrated among people with less severe and poorly defined mental health conditions.
