Policy of free GP care for children under 6 years: The impact on emergency department attendance

Abstract

Universal health coverage (UHC) aims to improve child health. Ireland, the only country in the European Union without universal access to primary care, introduced general practitioner (GP) care at no charge for children aged under six in 2015. This paper aims to evaluate the impact of this policy on attendance at the emergency department (ED). A difference-in-difference (DiD) analysis was applied to visit records of 367,000 paediatric patients at five hospitals over a period of five years, with treatment and control differentiated by age. DiD was also used to assess if GP referrals and the severity of presentations altered as a consequence of this policy. While existing research estimates that this policy increased attendance by children aged under six at general practice by over 25%, this policy did not lead to a reduction in ED attendance. Hospital level effects on attendance varied from no impact to increased attendance by children aged under six of 28.9%. While increased GP referrals, particularly for injury and medical reasons, indicated more patients presented to their GP prior to ED attendance, walk-ins without referral did not decrease. Attendance increased at both regional hospitals, which also had the highest proportion of GP referred visits. While the marginal probability of a visit being GP referred increased at four of the five hospitals in this study, only in two of these can the entire effect be attributed to the introduction of this policy (effects 1.4 and 1.8 percentage points). Previous unmet need, capacity constraints in general practice, regional variability in the GP to population ratio, restricted hours of access to GPs, coupled with faster access to diagnostics in the ED setting, may explain variability in the effect and why the expected reduction in ED attendances did not occur.
