The impact of Community Health Centers on inappropriate use of emergency services

Community Health Centers offer coordinated and comprehensive responses to primary care needs. Our study aims at assessing whether the introduction of such organizational model improved health outcomes measured by inappropriate emergency visits among diabetics in the Emilia‐Romagna region of Italy. Using difference‐in‐differences methods within a staggered treatment setting, we estimate the effect of Community Health Center participation on inappropriate hospital emergency visits between year 2010 and year 2016. We distinguish between emergency department admissions for varying time spans, occurring at daytime during working days, at night‐time, as well as during weekends. We show that, the causal effect of the adoption of the community care model leads to a reduction in the probability of inappropriate admissions by an amount ranging between 1.6 and 1.7% points during working days at daytime, with large facilities responsible for most gains by experiencing a decrease ranging between 4 and 3% points. Conversely, we detect no difference at night‐time and during weekends. Our results point out that the coordinated care model increases appropriateness among vulnerable patients, and that extending opening hours and the range of services can further enhance such benefits.
