Emergency Department Use in Children with Cerebral Palsy: A Data Linkage Study.

Abstract

To describe the pattern of emergency department (ED) consultations in children with cerebral palsy (CP) compared to controls and factors predictive of ED consultations. This retrospective cohort study linked data from the Registre de la paralysie cérébrale du Québec (REPACQ) and provincial administrative health databases. The CP cohort was comprised of children enrolled in REPACQ born between 1999 and 2002. REPACQ covers 6 of 17 Quebec health administrative regions. Region-, age-, and gender-matched controls were identified from administrative health databases in a 20:1 ratio. The primary outcome was high use of ED services (≥4 ED visits during the study period). Relative risk (RR) and 95% confidence interval (CI) were calculated. In total, 301 children with CP were linked to administrative data and 6040 peer controls were selected. Ninety-two percent (92%) of the CP cohort had at least one ED visit in the study period, compared to 74% among controls (RR 1.24, 95% CI 1.19-1.28). Children with CP were more likely than their peers to have high ED use (RR 1.40; 95% CI 1.30-1.52). Factors predictive of high ED use were comorbid epilepsy (RR 1.23; 95% CI 1.04-1.46) and severity of motor impairment (RR 1.14; 95% CI 0.95-1.37). Children with CP are more likely to present to the ED than their peers, resulting in increased use of ED services. Coordinated care with improved access to same-day evaluations could decrease ED use. Health system factors and barriers should be investigated to ensure optimal and appropriate use of ED services.
