“…In Australia, like many countries with universal health insurance, PHC service organisation and delivery varies across smallareas [12][13][14]. There is also evidence that service delivery characteristics, such as supply of primary care providers, scope of practice and after-hours arrangements, are associated with primary care service use [15][16][17] and perceived quality-of-care [18]. However, these findings were based on aggregated area-level data or examined practice-level service characteristics and individual outcomes.…”

BackgroundThere is limited data on system-level factors associated with equitable access to high-quality primary care. We examine whether individual-level socioeconomic variation in general practitioner (GP) quality-of-care varies by area-level organisation of primary healthcare (PHC) services.MethodsBaseline data (2006–2009) from the Sax Institute’s 45 and Up Study, involving 267,153 adults in New South Wales, Australia, were linked to Medicare Benefits Schedule and death data (to December 2012). Using multilevel logistic regression with cross-level interaction terms we quantified the relationship between small area-level PHC service characteristics and individual-level socioeconomic variation in need-adjusted quality-of-care (continuity-of-care, long-consultations, and care planning), separately by remoteness.Key findingsIn major cities, more bulk-billing(i.e. no co-payment) and chronic disease services and fewer out-of-pocket costs within areas were associated with an increased odds of continuity-of-care—more so among people of high-than low-education (e.g. bulk-billing interaction with university versus no school certificate 1.006[1.000,1.011]). While more bulk-billing, after-hours services and fewer OPC were associated with long-consultations and care planning across all education levels, in regional locations alone, more after-hours services were associated with larger increases in the odds of long consultations among people with low-than high-education (0.970[0.951,0.989]). Area GP availability was not associated with outcomes.ImplicationsIn major cities, PHC initiatives at the local level, such as bulk-billing and after-hours access, were not associated with a relative benefit for low-compared to high-education individuals. In regional locations, policies supporting after-hour access may improve access to long consultations, more so for people with low-compared to high-education.Key messagesWhat we knowEquitable access to high-quality primary healthcare is expected to reduce socioeconomic inequalities in health.Quality-of-care varies according to both individual socioeconomic position and local primary healthcare service organisation and delivery.However, there is limited data on system-level factors associated with equitable access to high-quality care.What this study addsIn major cities, area-level primary healthcare service characteristics such as bulk-billing (i.e. no co-payment), out-of-pocket costs, chronic disease and after-hours services were not associated with a relative benefit for low-education individuals compared with high-education in quality-of-care.In regional areas, more after-hours services were associated with a higher likelihood of long consultations – more so for people of low-education than high-education.How this study might affect research, practice or policyThe identified area-level service characteristics associated with socioeconomic variation in care indicate avenues for providers and policy makers for improving healthcare equity.Improved data measuring area-level primary healthcare service organisation is needed to better measure the impact of policy initiatives.
