Long-term effectiveness of a comprehensive pain management program: strengthening the case for interdisciplinary care

Chronic pain, a debilitating medical condition affecting approximately 15% of the US population, leads to individual suffering and costs to society in terms of health care dollars and lost productivity. To examine the effectiveness of a comprehensive pain management program, data from 108 program participants were evaluated. Preprogram, postprogram, and 6-month follow-up data were collected from 80 participants, and preprogram, postprogram, and 1-year data were collected from 46 participants. Outcomes data from several domains were assessed: pain severity, emotional distress, interference of pain on function, perceived control of pain, treatment helpfulness, and number of hours resting. Within-subject repeated-measure analyses of variance found statistically significant findings on the six outcome measures utilized in this study for both the 6-month and 1-year samples. Examination of 95% confidence intervals revealed no overlap in pretreatment scores with 6-month and 1-year outcomes in five of the six domains studied. Mean scores on emotional distress did not maintain statistical significance in the 6-month or 1-year review. Overall, this study strengthens the case for interdisciplinary care for chronic pain management and provides evidence for the long-term effectiveness of this therapy. Furthermore, this study lends support to the notion that interdisciplinary treatments are effective in targeting multiple domains affected by the pain condition.
