Long-term follow-up Results of a Combined Physical and Psychological Program for Patients with Chronic Low Back Pain

Abstract

Introduction For patients with persistent and disabling chronic low back pain (CLBP) who failed to improve after less intensive interventions, a combined physical and psychological (CPP) program including exercises and a cognitive behavioral approach, is recommended.1–3 These patients with CLBP participating in a two-week CPP-program improve in functional status and quality of life during the program and these positive results are maintained at one4 and at two-year follow-up assessment.5 Purpose To evaluate the long-term results of a short, intensive, evidence based CPP-program. Material and Methods A consecutive cohort study with a mean follow up of 6.5 years (range: 5.5–7.5) was performed. At follow up a response rate of 85% ( n = 277) was achieved. Primary outcome was functional status (Oswestry Disability Index [ODI;0–100]). Secondary outcomes were pain intensity, quality of life, and patient reported satisfaction. A Repeated Measures analysis of variance was used to identify changes over time. The two-week residential program is in line with recommendations in international guidelines1–3 and provided in collaboration with orthopedic spine surgeons at Sint Maartenskliniek Nijmegen, The Netherlands. Results At pre-treatment assessment the mean age was 46.1years (SD9.3) and the mean CLBP-duration 12.3 years (SD10.9). The mean ODI-score showed improvement at post-treatment and maintenance of results over time (ODI df[1,276],F = 0.146, p = 0.703). Secondary outcomes showed the same pattern. At long-term follow up more than half of the CLBP-patients (59.2%) showed a clinically relevant improvement of ≥10 points on the ODI and 45.3% of the patients reached a functional status equivalent to an acceptable, normal healthy population value (ODI ≤ 22). This is comparable to the one-year follow-up assessment. 80.1% of the participants are satisfied with the treatment results and 76.2% would recommend the program to family/friends. Conclusion The positive short-term effectiveness at one-year follow up of a two-week CPP-program is demonstrated to maintain over time. Patients demonstrate continued improvement of functional status and quality of life after 6.5 years of follow up. Moreover, at long-term follow up a high percentage of patients were satisfied with the results of the program and they would recommend the program to family and/or friends.
