Introduction: Chronic pain is in its nature multidimensional and is most successfully treated by a multidisciplinary approach. Some patients do not benefit from treatment, and psychological and socio-economic factors may play a major role. The present study investigated the ability of sociodemographic variables to predict the short-term effect of multidisciplinary treatment in patients with chronic pain who where referred consecutively to a Danish multidisciplinary pain centre.
Method: Pain scores (VAS) and health-related quality of life (HRQL) were assessed. On entry and three and six months later HRQL was evaluated by medical outcome short form (SF-36) and the psychological general well-being scale (PGWB). Sociodemographic variables were: age, gender, educational level, civil status employment status, and disability pension (DP) status.
Results: Of the sociodemographic variables evaluated, only the DP status seemed to be a significant outcome predictor. Patients applying for a DP do not improve. Patients receiving a DP and those who do not achieved moderate improvements, but these were significantly larger. The same pattern was seen for changes in psychological well-being and social functioning. The DP status predicted improvement in pain and social functioning.
Discussion: The present study indicates that the multidimensional problems experienced by patients applying for a DP are dominated by sociodemographic factors. Focus on the solution of these socio-economic problems is important, if patients with chronic pain are to benefit from multidisciplinary pain treatment.
