Examining the relationship between head trauma and opioid use disorder: A systematic review.

OBJECTIVE: To examine recent literature and determine common clinical risk factors between antecedent traumatic brain injury (TBI) and the following development of opioid misuse and provide a framework for clinical identification of at-risk subjects and evaluate potential treatment implications within this association. DESIGN: A comprehensive systematic literature search of PubMed was conducted for articles between 2000 and December 2022. Studies were included if the human participant had any head trauma exposure and any chronic opioid use or dependence. After eligibility criteria were applied, 16 studies were assessed for thematic trends. RESULTS: Opioid use disorder (OUD) risks are heightened in cohorts with head trauma exposed to opioids while in the hospital, specifically with tramadol and oxycodone. Chronic pain was the most common predictor of long-term OUD, and continuous somatic symptoms associated with the TBI can lead to long-term opioid usage. Individuals who present with coexisting psychiatric conditions pose significantly more risk associated with a higher risk of long-term opioid use. CONCLUSION: Findings indicate that therapists and clinicians must consider a risk profile for persons with TBI and follow an integrated care approach to account for mental health, prior substance misuse, presenting somatic symptoms, and current medication regimen during evaluation.

Exploring the link between ACEs and opioid use: A systematic review.

OBJECTIVE: To review the current literature surrounding the relationship between adverse childhood experiences (ACEs) and opioid use disorder (OUD) to guide clinical identification of high-risk individuals and assess treatment implications. DESIGN: A PubMed search was conducted from the year 2000 to 2022 using a series of primary and secondary search terms. A total of 21,524 unique results were screened for relevancy to ACEs and OUDs. After excluding unrelated articles, a total of 48 articles were included in this systematic review. RESULTS: Increased frequency of ACEs was directly related to increased risk of OUD and lower onset age. ACEs were also associated with OUD severity. ACEs linked to OUD included childhood neglect, emotional abuse, physical abuse, and sexual abuse. Additionally, dysfunctional childhood home environment, female gender, and psychiatric/behavioral comorbidities increased the risk of OUD, while resilience was found to be a protective factor. Multiple biochemical markers were associated with both ACEs and OUD. CONCLUSIONS: Children experiencing multiple ACEs should be the target of preventative intervention by medical professionals. Clinicians should include ACEs in their opioid misuse risk assessment. High incidence of co-occurring psychiatric/behavioral disorders provides multiple treatment avenues for patients with OUD. Resilience, along with being therapy target, should be fostered early in the life course. Incorporation of family members may improve opioid abuse treatment outcomes. Future research should focus on interventions interrupting the progression of ACEs to OUD along with proposed biochemical pathways.
