Antidepressant usage in the Canadian Forces.

This study was performed to evaluate the use of antidepressant medications among Canadian Forces (CF) members. A retrospective chart review was undertaken at seven CF bases for members who received antidepressant medications during a 6-month period. Data were collected on doses, duration, and types of antidepressant drugs, indications for therapy, and prescriber characteristics. Indications were classified as depression, anxiety disorders (including post-traumatic stress disorder [PTSD]), or nonpsychiatric conditions. A total of 1,024 charts were reviewed. Antidepressant usage rates were similar across sites for depression and anxiety but differed for PTSD. Rates of PTSD demonstrated more variability than did rates of depression or anxiety disorders among CF members. Antidepressant therapy is also frequently prescribed for nonpsychiatric disorders. Indications for the use of antidepressants thus varied among CF members at different bases. Better detection and treatment of depression may be required in this population.
