PRIME-MD: Its Utility in Detecting Mental Disorders in American Indians

Abstract

Objective: To examine the utility of using PRIME-MD (Primary Care Evaluation of Mental Disorders) for diagnosing mental disorders in American Indians. Method: One hundred randomly selected, adult, American-Indian patients who receive health care services at an urban Indian Health Service primary care clinic were evaluated for mental disorder by three primary care physicians using the PRIME-MD diagnostic assessment procedure. The main outcome measures were PRIME-MD diagnoses, diagnoses by an independent mental health professional, and treatment/referral decisions. Results: Eighteen percent of the patients had a threshold (met full DSM-IV criteria) PRIME-MD diagnosis, and an additional 17 percent had a subthreshold PRIME-MD diagnosis. The most frequently occurring PRIME-MD diagnoses were: probable alcohol abuse/dependence, major depressive disorder, and generalized anxiety disorder. Over 60 percent of the patients with a PRIME-MD diagnosis who were known “somewhat” or “fairly well” to their physician had not been recognized as having that psychiatric disorder prior to the PRIME-MD assessment. Therapy and/or referral was initiated for nineteen of the twenty-seven patients with a PRIME-MD diagnosis who were not previously receiving treatment. The primary care physicians were able to complete the PRIME-MD evaluations within an average of 7.8 minutes. There was a fair agreement between the PRIME-MD diagnoses and the diagnoses of the mental health professional (kappa = 0.56; overall accuracy rate = 79%). Conclusions: The present study represents the first formal examination of the use of PRIME-MD with American Indians. The results are encouraging. Further studies using PRIME-MD with other urban groups and reservation populations are recommended.
