Summary
High baseline pain interference and better physical performance predict better outcomes in chronic pain rehabilitation programs. These factors, rather than age or sex, are key indicators for successful interdisciplinary pain management.
Area of Science:
- Pain Management
- Rehabilitation Medicine
- Clinical Psychology
Background:
- Interdisciplinary pain management programs utilize cognitive-behavioral principles to enhance functioning and self-management in chronic pain patients.
- Current evidence is insufficient regarding psychological, biological, or social predictors of positive outcomes in pain rehabilitation.
- This study investigates predictors of change in Brief Pain Inventory (BPI) pain interference scores to identify factors influencing rehabilitation success.
Purpose of the Study:
- To evaluate predictors of change in Brief Pain Inventory (BPI) pain interference scores.
- To determine if age, sex, and baseline outcome measures predict improvement in pain interference after pain rehabilitation.
- To identify key indicators for successful interdisciplinary pain management.
Main Methods:
- Retrospective analysis of routinely collected clinical data from two pain rehabilitation programs (Balanced Life Programme and Get Back Active).
- Utilized standard and hierarchical regression analyses to identify predictors of change in BPI scores.
- Conducted responder analysis to assess the association between baseline measures and improvement.
Main Results:
- Higher baseline BPI scores and better physical performance measures predicted greater improvement in pain interference across both programs.
- Age and sex accounted for minimal variance in BPI change, with other measures explaining a significant portion (23% BLP, 19% GBA).
- Pain interference and physical performance were consistently significant predictors of improvement in pain rehabilitation.
Conclusions:
- High self-reported pain interference combined with better physical performance may indicate suitability for interdisciplinary rehabilitation.
- These factors serve as potential indicators for identifying patients likely to benefit from pain rehabilitation.
- Further validation of these findings is necessary to confirm their clinical utility.
