Background
Interdisciplinary pain management programs (IPMPs) are gold standard care for chronic pain, and are recommend for people with complex regional pain syndrome (CRPS). However no controlled trials have assessed their efficacy for CRPS.
Aims
To examine the efficacy of IPMPs for CRPS by comparing outcomes for people with CRPS with two groups for whom the efficacy of IPMPs is well established: those with chronic low back pain (LBP) and chronic widespread pain (CWP).
Methods
Retrospective data from people with CRPS (N=66) who had completed a 3-week IPMP at the Auckland Regional Pain Service were compared with age- and sex- matched controls with LBP (N=66) and CWP (N=66) who had completed the same program. Measures of pain intensity, pain-interference, pain catastrophizing, pain self-efficacy, depression, anxiety and stress pre- and post-programme, and at 1, 6 and 12 months were extracted. Latent class analysis was used to identify recovery trajectories, and chi-square analyses were used to identify whether outcome differed according to diagnostic group.
Results
Two recovery trajectories for pain interference and for pain intensity were identified. Following IPMPs, 58% of people were classified as belonging to a positive pain interference reduction trajectory whilst 12% were shown to be on a positive pain intensity reduction trajectory. Recovery trajectories were equal across the 3 diagnostic groups (CRPS, LBP, CWP) for both pain interference (χ2 = 1.8, p = 0.4) and intensity (χ2 = 0.2, p = 0.9).
Conclusion
IPMPs lead to significant improvements in pain intensity and pain interference, and are equally effective for people with CRPS, LBP and CWP. This supports current guidelines that people with CRPS should engage in IPMPs.
