Feasibility of the biopsychosocial primary care intervention 'Back on Track' for patients with chronic low back pain:a process and effect-evaluation

Purpose: Literature shows promising effects for interdisciplinary biopsychosocial rehabilitation programs in patients with chronic low back pain (CLBP). Not every patient needs an interdisciplinary rehabilitation trajectory provided in a secondary care setting. Patients with moderate complex psychosocial complaints might benefit from biopsychosocial interventions offered in primary care under supervision of a physician in rehabilitation medicine (i.e. biopsychosocial integrated care intervention). This study investigated the feasibility and effectiveness of such intervention in patients with CLBP with moderate complex psychosocial complaints.Methods: mixed-method. Patients (aged 18-65 years, low back pain >= 12 weeks, moderate complex psychosocial complaints) received the intervention (4 individual sessions, 8 group sessions) provided by trained primary care physiotherapists. Physicians in rehabilitation medicine provided one consultation afterwards. Data from patients (n = 18), physicians (n = 4) and physiotherapists (n = 12) were used.Results: Physiotherapists were satisfied with the training. Patient attendance was good for individual sessions, less for groups. Physiotherapists sufficiently delivered the intervention, although recruitment and contextual factors influenced delivery. Patients reported significantly reduced functional disability (Quebec Back Pain Disability Scale) post-treatment (-8.3, 95% CI -13.3 to -2.7) and at 3 months follow-up (-7.6, 95% CI -12.9 to -2.2).Conclusions: A biopsychosocial integrated intervention is feasible and potentially effective in patients with CLBP.
