Multidisciplinary pain treatment - Which patients do benefit?

Area of Science:

• Pain Management
• Health Services Research
• Quality of Life Studies

Background:

• Chronic non-malignant pain affects 14-50% of people in developed countries, significantly impairing health-related quality of life (HRQoL).
• Psychological distress, including depression and anxiety, is a key risk factor for pain chronicity and disability.
• Multidisciplinary pain management (MPM) addresses physical, psychological, and social factors to rehabilitate chronic pain patients.

Purpose of the Study:

• To examine changes in HRQoL after MPM in a large cohort of chronic pain patients.
• To identify patient-related factors predicting positive or negative HRQoL outcomes following MPM.
• To analyze differences between patients with significant HRQoL improvement versus those with decreased HRQoL.

Main Methods:

• A cohort of 439 patients undergoing MPM at a specialized clinic were assessed using the 15D HRQoL questionnaire.
• Detailed analysis of demographic, pain, psychological, and treatment characteristics for the top 100 responders and 100 non-responders.
• A three-year follow-up assessment evaluated sustained HRQoL changes post-MPM.

Main Results:

• HRQoL significantly improved in 45.6% of patients during MPM; 30.7% experienced a decrease.
• Higher education and better employment status were associated with better HRQoL outcomes.
• Psychiatric comorbidity showed a tendency towards being more prevalent in the non-responder group; more non-responders died during follow-up.

Conclusions:

• MPM demonstrates significant potential for improving HRQoL in chronic pain patients, even those with long-standing or complex pain conditions.
• Treatment outcomes are influenced by patient-related factors, particularly socioeconomic status and psychological well-being, rather than solely by pain characteristics.
• Individualized MPM approaches focusing on psychological symptoms and patient beliefs are crucial for optimizing outcomes, especially for patients at risk of poor response.
