Input: From 6168 studies identified in the searches, 41 RCTs with a total of 6858 participants were included. Methodological quality ratings ranged from 1 to 9 out 12, and 13 of the 41 included studies were assessed as low risk of bias. Pooled estimates from 16 RCTs provided moderate to low quality evidence that MBR is more effective than usual care in reducing pain and disability, with standardised mean differences (SMDs) in the long term of 0.21 (95% CI 0.04 to 0.37) and 0.23 (95% CI 0.06 to 0.4) respectively. The range across all time points equated to approximately 0.5 to 1.4 units on a 0 to 10 numerical rating scale for pain and 1.4 to 2.5 points on the Roland Morris disability scale (0 to 24). There was moderate to low quality evidence of no difference on work outcomes (odds ratio (OR) at long term 1.04, 95% CI 0.73 to 1.47). Pooled estimates from 19 RCTs provided moderate to low quality evidence that MBR was more effective than physical treatment for pain and disability with SMDs in the long term of 0.51 (95% CI -0.01 to 1.04) and 0.68 (95% CI 0.16 to 1.19) respectively. Across all time points this translated to approximately 0.6 to 1.2 units on the pain scale and 1.2 to 4.0 points on the Roland Morris scale. There was moderate to low quality evidence of an effect on work outcomes (OR at long term 1.87, 95% CI 1.39 to 2.53). There was insufficient evidence to assess whether MBR interventions were associated with more adverse events than usual care or physical interventions. Sensitivity analyses did not suggest that the pooled estimates were unduly influenced by the results from low quality studies. Subgroup analyses were inconclusive regarding the influence of baseline symptom severity and intervention intensity. Patients with chronic LBP receiving MBR are likely to experience less pain and disability than those receiving usual care or a physical treatment. MBR also has a positive influence on work status compared to physical treatment. Effects are of a modest magnitude and should be balanced against the time and resource requirements of MBR programs. More intensive interventions were not responsible for effects that were substantially different to those of less intensive interventions. While we were not able to determine if symptom intensity at presentation influenced the likelihood of success, it seems appropriate that only those people with indicators of significant psychosocial impact are referred to MBR.
Output:

We collected all the published studies up to February 2014; there were 41 studies (with 6858 participants) that compared multidisciplinary treatment to other treatments. Most studies compared a multidisciplinary treatment to usual care (such as care by a general practitioner) or to treatments that only addressed physical factors (such as exercise or physiotherapy). All the people in the studies had LBP for more than three months and most had received some other sort of treatment previously. There was moderate quality evidence that multidisciplinary treatment results in larger improvements in pain and daily function than usual care or treatments aimed only at physical factors. The difference was not very large, about 1 point on a 10 point scale for pain, but this may be important for people whose symptoms have not responded to other treatments. There was also moderate evidence that multidisciplinary treatment doubled the likelihood that people were able to work in the next 6 to 12 months compared to treatments aimed at physical factors. While these programs seem to be more effective than alternatives, the effects needs to be balanced with their costs in terms of money, resources and time. Multidisciplinary treatment programs are often quite intensive and expensive, so they are probably most appropriate for people with quite severe or complex problems.
