The potential role of social support in reducing risk of opioid misuse following traumatic injury

Background: Social support appears to play a pivotal role in the prevention, development, and remission of substance use disorders. Previous research suggests that interpersonal relationships moderate treatment outcomes for opioid use disorder based on the nature and quality of the relationship. However, the role of social support in the initiation of prescription opioid misuse (POM) is unclear. Methods: In a prospective cohort of 221 patients with traumatic injuries at a level 1 trauma center in Wisconsin, we used multiple linear regression analysis to examine the association between social support and POM at six months post-discharge. Covariates included morphine equivalent daily dose (MEDD) at baseline (24 h pre-discharge), opioid use at six months post-discharge, pre-injury depression and anxiety symptoms, and discharge pain intensity. Results: In models adjusted for relevant demographic and clinical outcomes, social support scores (beta = -3.898, p < 0.001; Bonferroni corrected) and depression and anxiety composite scores (beta = 2.29, p < 0.023; uncorrected) significantly predict POM scores 6 months post-discharge. When controlling for pre-injury depression and anxiety, patients with positive POM scores had significantly lower baseline social support scores than patients with negative POM (M = 24.31 vs 30.05, p = 0.003). Conclusions: Findings suggest that the perceived presence and quality of social support within an individual's life may influence the initiation of POM and should be considered in screening for risks related to potential POM. Providers may consider the use of social support when stratifying patients for risk of possible misuse.
