Abstract
Little is known about the rates and predictors of substance use treatment received in the Military Health System among Army soldiers diagnosed with a postdeployment substance use disorder (SUD). We used data from the Substance Use and Psychological Injury Combat study to determine the proportion of active duty (n = 338,708) and National Guard/Reserve (n = 178,801) enlisted soldiers returning from an Afghanistan/Iraq deployment in fiscal years 2008 to 2011 who had an SUD diagnosis in the first 150 days postdeployment. Among soldiers diagnosed with an SUD, we examined the rates and predictors of substance use treatment initiation and engagement according to the Healthcare Effectiveness Data and Information Set criteria. In the first 150 days postdeployment 3.3% of active duty soldiers and 1.0% of National Guard/Reserve soldiers were diagnosed with an SUD. Active duty soldiers were more likely to initiate and engage in substance use treatment than National Guard/Reserve soldiers, yet overall, engagement rates were low (25.0% and 15.7%, respectively). Soldiers were more likely to engage in treatment if they received their index diagnosis in a specialty behavioral health setting. Efforts to improve substance use treatment in the Military Health System should include initiatives to more accurately identify soldiers with undiagnosed SUD. Suggestions to improve substance use treatment engagement in the Military Health System will be discussed.
