Abstract
This study examined the prevalence of chronic pain alone, posttraumatic stress disorder (PTSD) alone, and both chronic pain and PTSD among U.S. Army soldiers during the postdeployment year.
The sample was 576,425 active duty soldiers returning from deployment in Afghanistan or Iraq between October 1, 2008, and September 30, 2014. Bivariate statistics were used to compare health care utilization among subgroups. Multivariate logistic regression with additional covariates was used to identify predictors of receiving an opioid days' supply of >30 days in the postdeployment year among soldiers with chronic pain, focusing on the effect of PTSD alone and on an interaction of PTSD with nonpharmacologic treatments (including therapeutic exercise, chiropractic treatment, acupuncture, and biofeedback).
In total, 12.2% of the soldiers received a chronic pain diagnosis, 5.1% a PTSD diagnosis, and 1.8% had both. Among soldiers with both conditions, 80.3% received nonpharmacologic treatment, and 31.4% received an opioid days' supply of >30 days. Among soldiers with chronic pain, comorbid PTSD and lack of nonpharmacologic treatment was associated with increased odds of receiving an opioid days' supply of >30 days (odds ratio [OR]=1.4, 95% confidence interval [CI]=1.3-1.6). PTSD combined with specific nonpharmacologic treatment modalities had a variable relationship with opioid receipt, and only PTSD with acupuncture or biofeedback was associated with reduced odds (OR=0.8, 95% CI=0.7-0.9).
Soldiers having both chronic pain and PTSD have significant health care needs. Although these soldiers accessed mental health care and received nonpharmacologic treatment, additional interventions are needed to mitigate protracted opioid utilization.
