BACKGROUND: Persistent postoperative pain is a significant problem for many children, particularly for those undergoing major surgery such as posterior spine fusion. More than two-thirds report persistent pain after spine fusion, yet factors that may contribute to poorer outcomes remain poorly understood. AIMS: This prospective, longitudinal study examined how psychologic and somatic symptoms cluster together in children aged 10-17 years with idiopathic scoliosis, and tested the hypothesis that a higher psychological and somatic symptom cluster would predict worse pain outcomes 1 year after fusion. METHODS: Otherwise healthy children with idiopathic scoliosis completed preoperative surveys measuring recent pain intensity, pain location(s), somatic symptom severity, painDETECT (neuropathic-type pain symptoms), pain interference, fatigue, depression, anxiety, and pain catastrophizing. Pain outcome data were collected during hospitalization, and at 1 year after surgery. RESULTS: Ninety-five children completed baseline surveys and a cluster analysis differentiated 28 (30%) with a high symptom profile that included; higher depression, fatigue, pain interference, catastrophizing, and painDETECT scores. High symptom cluster membership independently predicted higher pain interference at 1 year (β 9.92 [95% CI 6.63, 13.2], P < 0.001). Furthermore, children in this high symptom cluster reported significantly higher pain intensity and painDETECT scores, and had a 50% higher probability of continued analgesic use at 1 year compared to those in the Low Symptom Cluster (95% CI 21.3-78.5, P = 0.001). CONCLUSION: Findings from this exploratory study suggest a need to comprehensively assess children with scoliosis for preoperative signs and symptoms that may indicate an underlying vulnerability for persistent pain. This, in turn may help guide a comprehensive perioperative treatment strategy to mitigate the potential for long-term pain trajectories.
