PTSD Care Among Veterans With and Without Co-Occurring Substance Use Disorders

Factors associated with receipt of minimally adequate psychotherapy for PTSD at the Veterans Health Administration

BACKGROUND

Despite Veterans Health Administration (VHA) efforts, many Veterans do not receive minimally adequate psychotherapy (MAP) for posttraumatic stress disorder (PTSD). It is important to understand factors associated with receipt of PTSD MAP (at least eight sessions) so that we may tailor efforts to increase treatment utilization for those who experience the greatest barriers to care.

METHODS

Participants were 2008 post-9/11 Veterans who participated in a nationwide survey and had a PTSD diagnosis documented in the VHA electronic health record (EHR) before 2018. Participants self-reported sociodemographic information and trauma history. Service utilization data (e.g., PTSD MAP) were obtained from EHR. Logistic regression was used to model factors associated with PTSD MAP.

RESULTS

Only 24% of Veterans (n = 479) received PTSD MAP. Veterans who reported that they were not employed and had reported history of military sexual trauma were more likely to have received PTSD MAP.

CONCLUSIONS

Understanding and addressing barriers to PTSD care for Veterans who are employed could help improve PTSD treatment utilization for this group.

Treatment Utilization for Posttraumatic Stress Disorder in a National Sample of Veterans and Nonveterans

OBJECTIVE

The current study sought to compare rates of posttraumatic stress disorder (PTSD) treatment utilization (medication and psychotherapy) among veterans and nonveterans-and to investigate which factors are associated with treatment utilization among veterans versus nonveterans.

METHODS

Participants were 2775 individuals (veteran, n=2508; nonveteran, n=267) meeting criteria for probable PTSD (determined by the PTSD Checklist) drawn from a nationwide, population-based survey. Participants reported demographic information, trauma history, mental health symptoms, insurance coverage, and treatment history.

RESULTS

Analyses revealed that the majority of veterans and nonveterans with probable PTSD had not received any PTSD treatment (56% of veterans and 86% of nonveterans). Population-weighted logistic regression models demonstrated that veterans with probable PTSD were substantially more likely to receive medication and psychotherapy for PTSD than nonveterans with probable PTSD. Logistic regression models demonstrated that, among veterans, having Veterans Affairs health care coverage was most strongly associated with receiving PTSD medication and psychotherapy. Black (vs. White) veterans were less likely to have received PTSD medication and psychotherapy. In contrast, among nonveterans, being married or divorced (vs. never married) was most strongly associated with receiving PTSD medication, and reporting a history of sexual trauma was most strongly associated with receiving PTSD psychotherapy.

CONCLUSION

Given that most individuals do not receive PTSD treatment, additional understanding of treatment barriers and facilitators for both veterans and nonveterans is needed to improve intervention reach.

Rates and predictors of psychotherapy receipt among U.S. veterans with comorbid posttraumatic stress disorder and substance use disorders

Introduction

Veterans with comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD) have complex needs and often do not receive adequate mental health treatment. The purpose of this study was to examine rates and predictors of PTSD-only, SUD-only, or PTSD and SUD psychotherapy receipt among newly diagnosed Veterans with PTSD and SUD.

Design and setting

An administrative dataset including Veterans Health Administration (VHA) users.

Participants

The sample comprised 32,779 United States Veterans with a new PTSD and a new SUD diagnosis in fiscal year 2015.

Measurement

Multinomial logistic regression was used to identify predictors of receipt of any and adequate psychotherapy for PTSD, SUD, or PTSD and SUD across settings. Binomial logistic regression was used to identify predictors of PTSD psychotherapy among those who received any psychotherapy.

Findings

A total of 13,824 (42.17%) Veterans in this sample received any PTSD- or SUD-related therapy in the year following diagnosis. Low rates of veterans received an adequate dose of PTSD-related psychotherapy (6.58%), SUD-related psychotherapy (7.72%), or both PTSD and SUD-related psychotherapy (<1%) In adjusted models, older age, service-connected disability, and psychiatric comorbidities were associated with decreased odds of treatment. Specific types of SUDs, including alcohol, cocaine, and opioid use disorders, along with receipt of diagnosis in a PTSD or SUD clinic, were associated with increased odds of treatment.

Conclusions

Low rates of PTSD and SUD related psychotherapy highlight a need to better engage and retain Veterans with these disorders in care. Predictors of decreased treatment utilization, such as older age, service connection, and bipolar and major depressive disorders, may inform efforts by the VHA to further target and engage Veterans with indicated treatments.
