Efficacy of a Psychosocial Pain Management Intervention for Men and Women With Substance Use Disorders and Chronic Pain: A Randomized Clinical Trial.

ABSTRACT:

Importance

Chronic pain is common in those with substance use disorders (SUDs) and predicts poorer addiction treatment outcomes. A critical challenge for addiction treatment is to develop effective methods to improve pain-related and substance use-related outcomes for those in treatment for SUDs.

Objective

To examine the efficacy of an integrated behavioral pain management intervention (Improving Pain During Addiction Treatment [ImPAT]) for men and women with SUDs to treat pain, functioning, and substance use.

Design, setting, and participants

In this randomized clinical trial, 8 sessions of ImPAT were compared with 8 sessions of a supportive psychoeducational control (SPC) condition for adults with pain treated at a large residential SUD treatment program. Follow-up occurred at 3, 6, and 12 months postbaseline. A total of 1372 adults were screened, including 960 men and 412 women, and 510 adults were randomized, including 264 men and 246 women. The goal was to recruit approximately equal numbers of men and women to examine results separately in men and women. A total of 470 of 510 participants (92.2%) completed at least 1 follow-up assessment. Data were collected from October 3, 2011, to January 14, 2016. Data were analyzed from February 1, 2016, to May 1, 2020.

Interventions

ImPAT focused on how a psychosocial model of pain was associated with functioning and relapse prevention and provides skills to manage pain. SPC served as the active control condition and involved discussions of topics like nutrition and the course of addiction, which were intended to be relevant to the patient population and to have face validity but be distinct from the content of ImPAT.

Main outcomes and measurements

The primary outcomes were pain intensity, pain-related functioning, and behavioral pain tolerance at 12 months. Secondary outcomes were frequency of alcohol and drug use over 12 months.

Results

Of the 510 included participants, the mean (SD) age was 34.8 (10.3) years. A total of 133 men and 122 women were assigned to ImPAT, and a total of 131 men and 124 women were assigned to the SPC condition. Over 12 months of follow-up, randomization to the ImPAT intervention was associated with higher tolerance of pain among men, higher by a mean score of 0.11 (95% CI, 0.03 to 0.18; P = .004; Cohen d = 0.40) at 3 months and by 0.07 (95% CI, -0.01 to 0.19; P = .11; Cohen d = 0.25) at 12 months. Women receiving the ImPAT intervention experienced a reduction in pain intensity from 3 to 12 months, while women receiving the SPC condition experienced an increase in pain intensity, resulting in lower pain in the ImPAT condition by a mean score of 0.58 (95% CI, -0.07 to 1.22; P = .08; Cohen d = -0.22) at 12 months. No differences were found between the ImPAT and SPC conditions on alcohol or drug use.

Conclusions and relevance

Behavioral pain management is not typically included in addiction treatment, but the present results indicate that this type of intervention was associated with better pain-related outcomes, including pain tolerance in men and pain intensity in women. Improvements in substance use-related outcomes beyond that achieved by treatment as usual were not observed. Treatment programs should consider providing psychosocial pain management services to augment standard addiction treatment.

Project description:BackgroundMany leaders in the field of chronic pain treatment consider interdisciplinary pain management programs to be the most effective treatments available for chronic pain. As programs are instituted and expanded to address demands for nonpharmacological chronic pain interventions, we need to better understand how patients experience program impacts, as well as the challenges and supports patients encounter in trying to maintain and build on intervention gains.MethodsWe conducted a qualitative evaluation of an interdisciplinary chronic pain coaching program at the Atlanta Veterans Affairs. A purposive sample of Veterans were engaged in interviews (n=41) and focus groups (n=20) to elicit patient outcomes and barriers and facilitators to sustainment of improvements. Transcripts were analyzed using matrix and thematic analyses.ResultsVeterans reported various outcomes. Most frequently they described adopting new self-care or lifestyle practices for pain management and health. They also often described accepting pain, being better able to adjust and set boundaries, feeling more in control, participating in life, and changing their medication use. A small portion of the sample reported no improvement in their conditions. When outcomes were examined as a whole, individuals described impacts that could be placed along a spectrum from whole life change to no change. Facilitators to maintenance of improvements included having building blocks (eg, carrying forward practices learned), support (eg, access to resources), and energy (eg, motivation), and improving incrementally. Challenges were not having building blocks (eg, life disruptions), support (eg, unknown follow-up options), and energy (eg, competing demands) and having an unbalanced rate of improvement.ConclusionMost Veterans identified experiencing multiple areas of improvement, especially learning about and taking up new pain and general health management skills. Ensuring participants can build on and find support for these outcomes when applying what they have learned in their dynamic social and physical worlds remains a challenge for this program and other relatively short-term interdisciplinary chronic pain interventions.
