Background: Recent health service policies in the UK have focused on improving primary care access in order to reduce the use of costly emergency department services, even though the relationship between the two is based on weak or little evidence. Research is required to establish whether improving primary care access can influence emergency department attendance. Aim: To ascertain whether a relationship exists between the degree of access to GP practices and avoidable emergency department attendances in an inner-London primary care trust (PCT). Design and setting: Observational, cross-sectional ecological study in 68 general practices in Brent Primary Care Trust, north London, UK. Method: GP practices were used as the unit of analysis and avoidable emergency department attendance as the dependent variable. Routinely collected data from GP practices, Hospital Episode Statistics, and census data for the period covering 2007-2009 were used across three broad domains: GP access characteristics, population characteristics, and health status aggregated to the level of the GP practice. Multiple linear regression was used to ascertain which variables account for the variation in emergency department attendance experienced by patients registered to each GP practice. Results: None of the GP access variables accounted for the variation in emergency department attendance. The only variable that explained this variance was the Index of Multiple Deprivation (IMD). For every unit increase in IMD score of the GP practice, there would be an increase of 6.13 (95% CI = 4.56, 7.70) per 1000 patients per year in emergency department attendances. This accounted for 47.9% of the variance in emergency department attendances in Brent. Conclusion: Avoidable emergency department attendance appears to be mostly driven by underlying deprivation rather than by the degree of access to primary care.
