What factors predict outcome from an inpatient multidisciplinary chronic pain service? A prospective cohort study.

Objective: To identify baseline factors associated with outcomes from an inpatient multidisciplinary pain management program (PMP) located in a bicultural area of Aotearoa New Zealand. Methods: A prospective cohort study was undertaken involving 164 people with chronic pain who attended the PMP. Demographic, clinical, and psychosocial measures were obtained at baseline, whereas clinical and psychosocial outcome measures were also obtained at program discharge and 3-month follow up (N = 100). Multivariate analyses were used to determine baseline demographic variables that were associated with outcomes at discharge and follow up. Results: Being male and working full-time were associated with poorer outcomes in select measures at discharge. At the 3-month follow up, Māori ethnicity, working full-time, being retired or unemployed, or having chronic widespread pain were associated with poorer outcomes for some measures, whereas those with rheumatoid arthritis had greater self-efficacy. Conclusions: Sex, ethnicity, employment status, and patient condition impact clinical outcomes from the program and in the time from discharge to follow up. Program content and/or delivery should be altered to promote more equitable outcomes for all patients in the long term. What is known about the topic? Multidisciplinary pain management programs (PMPs) are the best treatment for chronic pain, but not everyone benefits from such programs to the same extent. What does this paper add? Ethnicity, employment status, and pain condition are associated with PMP outcomes, but mainly in the long term. What are the implications for practitioners? Program content, delivery, and follow up should be adapted to facilitate equity in long-term outcomes. [ABSTRACT FROM AUTHOR]
