Education level and hospitalization for ambulatory care sensitive conditions: an education approach is required

Studies in several different countries and settings suggest that ambulatory care-sensitive conditions (ACSCs)-related hospitalizations could be associated more with socioeconomic variables than with the quality of primary healthcare services. The aim of the present study was to analyze the potential links between education levels or other social determinants and ACSC-related hospitalization rates.

We analyzed a total of 467 504 records of ordinary discharges after acute hospitalization in 2015-16 for patients 20-74 years old residing in the Veneto Region. We calculated the prevention quality indicators (PQIs) developed by the Agency for Healthcare Research and Quality. Rate ratios (RRs) and 95% confidence intervals (95% CIs) were estimated with a set of Poisson regressions to measure the relative risk by sociodemographic level.

Hospitalizations for ACSCs accounted for 3.9% of all hospital admissions (18 436 discharges), and the crude hospitalization rate for ACSCs among 20- to 74-year-olds was 26.6 per 10 000 inhabitants (95% CI, 25.8-27.4). For all conditions, we found a significant association with formal education. In the case of the overall composite PQI#90, e.g. poorly educated people (primary school or no schooling) were at significantly higher risk of hospitalization for ACSCs than the better educated (RR, 4.50; 95% CI, 4.13-4.91).

Currently available administrative data regarding ACSCs may be used effectively for reveal equity issues in the provision of health care. Our results indicate that an educational approach inside Primary Health Care could address the extra risk for preventable healthcare demands associated with poorly educated patients.
