As reported in the journal Health Affairs, antidepressant drugs are the third most commonly prescribed class of medications in the U.S. Much of the growth of these drugs has been fueled by prescriptions written by nonpsychiatrist caregivers, and are not accompanied by a psychiatric diagnosis.
Between 1996 and 2007, the proportion of doctor visits at which antidepressants were prescribed but no psychiatric diagnoses were noted increased from 59.5% to 72.7%.
Researchers aren’t saying that this remarkable growth necessarily represents inappropriate use of antidepressants, and depression is underdiagnosed and undertreated in this country. But the rapid and marked increase of such prescribing habits have prompted researchers to call for scrutiny of the pattern to better understand the factors driving the trend and to develop “effective policy responses.”
Ramin Mojtabai, one of the study’s authors and a professor in the department of mental health at Johns Hopkins in Baltimore, said to WebMD, “What we are observing is that Americans are increasingly viewing psychiatric medications as a solution for a wide range of social and interpersonal problems and for dealing with daily stress [and] general medical providers appear to be going along with this trend. The irony is that many patients with major depression or anxiety disorders who could potentially benefit from treatment with antidepressant medications do not receive these treatments.”
Another source told WebMD that there may be another story line here. Doctors often get reimbursed at lower rates for treating psychiatric conditions, so they might be motivated to prescribe antidepressants but record them in patient charts as treatment for a nonpsychiatric problem. And there’s still a stigma attached to psychiatric illnesses, which could skew diagnoses.
The study authors suggest that if antidepressants are being prescribed for uses not supported by clinical evidence, there might be a need to improve providers’ prescribing practices, revamp drug formularies or vigorously pursue implementation of broad reforms of the health-care system. The point is to improve communication between primary care providers and mental health specialists.
