PurposeThe purpose of this research was to describe 24-42 month outcomes of a combined inpatient/day hospital interdisciplinary pain rehabilitation program for children and adolescents with chronic pain and functional disability.MethodsOne-hundred-seventy-three children and adolescents (mean age=15.1 years, SD=2.5) were treated in the three-week program. Mixed effects regression models (MERM) examined changes over time in pain ratings (0-10), school days missed by children and work days missed by parents in the preceding week, and the number of days hospitalized in the preceding month.ResultsParticipants reported a significant decline in pain from admission to 24-42 month follow-up. The largest declines in pain occurred from discharge to 1-month follow-up (6.20 vs. 4.81 on a 0-10 numerical rating scale) and from 12 months to 24-42 month follow-up (4.90 vs. 3.56). Two distinct trajectories of treatment response were identified using growth mixture modeling: children with initially high pain ratings exhibited large reductions in pain ratings, while those with lower pain ratings at admission showed minimal reductions. Treatment resulted in significant reductions in school and work days missed and the number of days hospitalized (all p's < 0.001), with reductions evident at 1-month follow-up and maintained through 24-42 month follow-up.ConclusionsThese results suggest that interdisciplinary pain rehabilitation is a promising approach to chronic pain and associated disability in children, with enduring improvements found 24-42 months following program completion. Distinct trajectories of treatment response were identified.
