Can the back-to-work rate of patients with long-term non-malignant pain be predicted?

The objective of this study was to evaluate the outcome of a structured multidisciplinary rehabilitation programme regarding the return-to-work rate. Sixty-seven patients were enrolled in an 8-week, structured rehabilitation programme. The prediction of the return-to-work rate was evaluated before entering the programme. The patients' own perception of returning to work as well as their pain intensity were estimated on a visual analogue scale and their period of sick leave was also recorded. The multidisciplinary rehabilitation team made an impairment and disability evaluation and analysis (IDEA) to assess possible work ability. This evaluation was made during the first 3 weeks of the 8-week programme. The return-to-work rate was also evaluated by means of the modified somatic perception questionnaire (MSPQ) and the disability rating index (DRI) before entering the programme. The results were compared with the actual return-to-work rate 1 year after completing the programme. A comparison group of 14 patients who were rejected due to lack of space in the programme was used in this study. There was a positive, statistically significant correlation (P<0.01) between the evaluation of the multidisciplinary rehabilitation team and the actual outcome of the return-to-work rate 1 year after completing the programme. At the 1-year follow-up, 63% of the patients had returned to work or were in work-related activities. The results on MSPQ or DRI, the patients' own perception of returning to work, the pain intensity, age or the period of time out of work did not predict the return-to-work ability. This study has shown that 63% of the patients with long-term non-malignant pain were back to work or in work-related activities 1 year after completing the rehabilitation programme. The IDEA made by the rehabilitation team was crucial in predicting the return-to-work rate in this patient group. The MSPQ and DRI questionnaires, the patients' own prediction, pain intensity, age and time out of work had a low value for predicting the return-to-work rate following a structured multidisciplinary rehabilitation programme.
