[Evaluation of a multimodal pain therapy at the University Pain Centre Dresden]. / Evaluation einer multimodalen Schmerztherapie am UniversitätsSchmerzCentrum Dresden.

BACKGROUND: Data of a multimodal pain management program of the multidisciplinary pain management centre at the University Hospital of Dresden is presented. Over a period of 4 weeks, supplemented by an additional week 3 months later (booster week), patients with chronic pain of different origins are being treated in groups of 12. Based on the principles of the biopsychosocial pain model and the idea of functional restoration, the program is dedicated for pain patients where outpatient treatment was insufficient. METHODS: The program was evaluated on the basis of pain intensity (NRS), pain disability (PDI), fear and depression (HADS-D), catastrophizing (CSQ) and health-related quality of life and vitality (SF-36). The data were collected at the beginning and end of the initial 4 week treatment period, at the end of the booster period as well as 6 and 12 months after the end of active treatment. RESULTS: A total of 189 patients were included in the program in the period from January 2006 until August 2008. All outcome parameter showed statistically significant improvements with small to high effect sizes (ES 0.20-0.95). The results stayed stable even 1 year after the treatment. The highest effect sizes were found in catastrophizing (ES 0.86) and average pain intensity (ES 0.95). The primary pain diagnosis (e. g. low back pain versus headache) had no impact on treatment outcome. CONCLUSION: Significant and clinically relevant improvements could be achieved with the multimodal pain management program in groups of 12 patients. The results were stable over a time period of 1 year. Pain diagnosis had no impact on the outcome.
