Objective: To systematically review and synthesize evidence of determinants associated with hospital-based health service utilization among individuals with cerebral palsy (CP).
Data sources: Electronic databases MEDLINE, Embase, APA Psycinfo were searched from January 2000 to April 2020.
Study selection: Observational studies were included that described people with CP, reported quantitative measures of hospital-based health service utilization (inpatient, outpatient, emergency department), and based in high-income countries. We excluded studies that included only subsets of people with CP, or those that only reported therapy service utilization.
Data extraction: After initial screen, 2 reviewers reviewed full texts for inclusion and performed data extraction and risk of bias assessment using the Newcastle-Ottawa scale. Determinants of health service utilization were identified and categorized using the Andersen behavioral model.
Data synthesis: Seventeen studies met inclusion criteria. Study quality was high. Twenty-six determinants were reported across 8 Andersen model characteristics. Individual predisposing factors such as sex showed no difference in health service utilization; inpatient admissions decreased with increasing age during childhood and was lower in adults. Increased health service utilization was associated with "individual need" including severe gross motor disability, epilepsy, developmental/ intellectual disability and gastrostomy-use across inpatient, outpatient and emergency department settings. There was little information reported on socio-demographic and health system contextual determinants.
Conclusions: CP health service utilization is associated with age, severity and comorbidities. Improved understanding of determinants of health service utilization can support health service access for people with CP.
