Payor, Patient Ethnicity Impact Antidepressant Prescribing

Payor, Patient Ethnicity Impact Antidepressant PrescribingA new study discovers African-Americans and Hispanics with major depressive disorder are less likely to receive antidepressants than Caucasian patients. And Medicare and Medicaid patients were less likely to get the latest antidepressants.

The findings come from a study by researchers from the University of Michigan School of Public Health. They examined data from 1993 to 2007 to try to understand the antidepressant prescribing patterns of physicians.

Researchers studied who received antidepressants, and what type of antidepressant was prescribed. They found that race, payment source, physician ownership status and geographical region influenced whether physicians decided to prescribe antidepressants in the first place.

Age and payment source influenced which types of antidepressants patients received.

The study found that Caucasians were 1.52 times more likely to be prescribed antidepressants than Hispanic and African-American patients being treated for major depressive disorders.

Race was not a factor in the physician’s choice of a specific type of antidepressant medication.

“This study confirmed previous findings that sociological factors, such as race and ethnicity, and patient health insurance status, influence physician prescribing behaviors,” said Rajesh Balkrishnan, Ph.D., principal investigator and associate director for Research and Education, University of Michigan Center for Global Health. “This is true in particular for major depressive disorder treatment.”

Newer antidepressants, such as serotonin–norepinephrine reuptake inhibitor (SNRI’s) and selective serotonin reuptake inhibitor (SSRI’s) are considered the best option for major depressive disorder. Older generation drugs such as tricyclic antidepressants, monoamine oxidase inhibitors and others tend to have more side effects.

Researchers discovered that that Medicare and Medicaid patients were 31 percent and 38 percent less likely to be prescribed antidepressants, respectively, compared to those with private insurance.

Geography and physician ownership status also factored into which patients received antidepressants. Sole practitioners compared to non-owners were 25 percent less likely to prescribe antidepressants, and physicians in metropolitan areas were 27 percent less likely to prescribe antidepressants in all patients with depression.

However, physicians who had seen the patients before were 1.4 times more likely to prescribe antidepressants.

Researchers also analyzed which patients received the newer antidepressants or the older antidepressants. Findings included:

  • An increase in patient age was associated with a 7 percent decreased likelihood of physicians’ prescribing only SSRI/SNRI antidepressants compared to only older antidepressants;
  • Compared to private insurance, Medicare and Medicaid patients were 58 percent and 61 percent less likely to be prescribed only newer antidepressants, respectively;
  • HMO patients had a 2.19 times higher likelihood of being prescribed only other newer antidepressants;
  • Compared to the West, physicians who practiced in the Northeast were 43 percent less likely to prescribe other newer antidepressants only, and 43 percent less likely to prescribe combined therapy for patients.

Researchers believe the study highlights the need to improve physician practice guidelines, a action that will eliminate unnecessary variations among physician practices and help obtain optimal health care for patients.

The research is found online in the International Journal of Psychiatry in Medicine.
