Health-related quality of life and caregiver burden after hip reconstruction and spinal fusion in children with spastic cerebral palsy

Abstract

Aim: To evaluate the effect of hip reconstruction or spinal fusion on health-related quality of life (HRQoL) in non-ambulatory children with spastic cerebral palsy (CP) and caregiver burden. Method: This was a prospective, longitudinal study of changes in HRQoL and caregiver burden over the 5 years after surgical correction of hip instability or scoliosis in children with bilateral spastic CP classified in Gross Motor Function Classification levels IV or V. Serial parent proxy measures of HRQoL and caregiver burden were obtained before and 6 weeks, and 3, 6, 9, 12, 24, and 60 months after surgery using the Caregiver Priorities and Child Health Index of Life with Disabilities and the Assessment of Caregiver Experience with Neuromuscular Disease. Scores 5 years or more after surgery were compared to pre-surgery scores using paired Student’s t-tests. Serial outcome trajectories were estimated by linear mixed modeling. Results: Of 69 participants (40 males, 29 females; mean age 11y 6mo, SD 4y 1mo, range 3y 10mo–20y 7mo), 43 had hip reconstruction and 26 had spinal fusion. Clinically significant improvements in HRQoL were detected (average increase 7.6 points) 5 years or more postoperatively, with hip reconstruction providing greater benefit. Domains improved by surgery included positioning, transferring/mobility, comfort/emotions, and health. Caregiver burden did not change as these children remain maximally dependent. Interpretation: Surgical treatment of hip and spine deformity improves HRQoL, especially for painful hip instability, but does not change caregiver burden.
