Interaction of Broadband Access and Education Levels in Determining the Rate of Emergency Medical Admissions.

We examined the effect of broadband access, educational status and their interaction on local population health. We calculated the annual admission incidence rates for each small area population unit within our hospital catchment, relating quintiles of broadband access to two groups a) full time education to primary level (less than or equal to 15 years) and b) full time education to tertiary level (>18 years). Univariate and multivariable risk estimates were calculated, using truncated Poisson regression. 82,368 admissions in 44,628 patients were included. Broadband access was a linear predictor of the admission incidence rate with decreases from Q1 (least access) 50.8 (95%CI 30.2 to 71.4) to Q5 (highest access) 17.9 (95%CI 13.4 to 22.4). Areas with greater numbers educated only to primary level were more influenced by broadband access. Broadband access is a predictor of the emergency medical admission rate; this effect is modulated by the baseline education level.
