The family physician as medical review officer.

BACKGROUND The medical review officer is a position established by federal statute in 1988. The role of the medical review officer is to interpret positive urine drug tests in view of the donor's medical history. With more than 4 million workers affected by the Department of Transportation guidelines for workplace drug testing, and many private employers having urine drug screening programs, there is a need for medical review officers. METHODS Materials for this report were collected while the first author was pursuing certification from the Medical Review Officer Certification Council. Much of the data was published in the Federal Register from 1988 through 1993. RESULTS AND CONCLUSIONS Urine drug testing is divided into three stages: collection, laboratory analysis,and medical review of results. Because the workplace urine drug test is a forensic test, the urine is collected under strict chain of custody. Analysis of specimens is conducted by laboratories that have met stringent technical criteria and are approved by the Substance Abuse and Mental Health Services Administration (formerly the National Institute on Drug Abuse). Family physicians are in a unique position to become medical review officers because of their training and professional roles. Educational programs are available for physicians interested in becoming a medical review officer.
