Emergency Department non-urgent visits and hospital readmissions are associated with different socio-economic variables in Italy

Abstract

Objective: The aim of this paper was to evaluate socio-economic factors associated to poor primary care utilization by studying two specific subjects: the hospital readmission rate, and the use of the Emergency Department (ED) for non-urgent visits. Methods: The study was carried out by the analysis of administrative database for hospital readmission and with a specific survey for non-urgent ED use. Results: Among the 416,698 sampled admissions, 6.39% (95% CI, 6.32-6.47) of re-admissions have been registered; the distribution shows a high frequency of events in the age 65-84 years group, and in the intermediate care hospitals (51.97%; 95%CI 51.37-52.57). The regression model has shown the significant role played by age, type of structure (geriatric acute care), and deprivation index of the area of residence on the readmission, however, after adjusting for the intensity of primary care, the role of deprivation was no more significant. Non-urgent ED visits accounted for the 12.10%, (95%CI 9.38-15.27) of the total number of respondents to the questionnaire (N = 504). The likelihood of performing a non-urgent ED visit was higher among patients aged <65 years (OR 3.2, 95%CI 1.3-7.8 p = 0.008), while it was lower among those perceiving as urgent their health problem (OR 0.50, 95%CI 0.30-0.90).
