2020
Abstract Background Knowing the distinctive features of patients with the highest utilization of the emergency department (ED) is paramount to finding adequate alternatives to ED care for selected patients and improving health care quality and efficiency. Objective This study aimed to identify ED high-frequency users and compare their clinical and utilization characteristics with other ED users. Methods Secondary data analysis of ED visits and patients database from a Portuguese public urban hospital. Retrospective study of adults visiting the ED in 2016 (61,403 patients; 95,643 visits), comparing demographic and clinical characteristics of patients and clinical and temporal characteristics of ED visits between high-frequency users (>10 ED visits in 2016) and frequent (4–10 ED visits) and nonfrequent (1–3 ED visits) users. Results We identified 169 high-frequency users (0.3% of patients and 3.0% of ED visits) with an average number of 16.9 visits in 2016. Patients in this group were older (61.8 years; frequent users: 61.2 years; nonfrequent users: 53.4 years; p Conclusion High-frequency users are an aged and heterogeneous group, requiring tailored interventions to improve care.
