Predictors of Responsivity to Interdisciplinary Pain Management

Area of Science:

• Pain Management
• Rehabilitation Medicine
• Clinical Psychology

Background:

• Identifying predictors of treatment success in interdisciplinary pain management (IPM) is crucial for optimizing patient outcomes.
• Patient-treatment matching algorithms can enhance the effectiveness of chronic pain rehabilitation programs.

Purpose of the Study:

• To determine which patient characteristics predict successful outcomes in an interdisciplinary pain management (IPM) program.
• To identify subgroups of patients most likely to benefit from IPM to inform treatment matching.

Main Methods:

• Prospective study of 163 adults admitted to a two-week IPM program.
• Collected self-report questionnaires and physical performance measures at program entry and completion.
• Utilized group-level and individual-level analyses, including multivariate analysis of variance and logistic regression.

Main Results:

• Significant improvements observed across psychological, social, and physical domains, with up to 50% achieving clinically meaningful improvements.
• Higher baseline depression, anxiety, stress, and pain catastrophizing predicted better group-level outcomes.
• Individuals with higher baseline depression were most likely to show significant individual-level improvement. Nociceptive pain and older age were associated with greater multidomain response.

Conclusions:

• Interdisciplinary pain management (IPM) leads to significant improvements in physical, psychological, and social outcomes for a substantial proportion of patients.
• High baseline depression reliably predicts individual-level improvement in IPM.
• Nociceptive pain and older age are associated with the greatest response across multiple outcome domains.
