ObjectivesOur aim was to compare some of the health outcomes and costs associated with value of care in emergency departments (ED) and walk-in clinics for ambulatory patients presenting with an acute respiratory disease.MethodsA health records review was conducted from April 2016 through March 2017 in one ED and one walk-in clinic. Inclusion criteria were: (i) ambulatory patients at least 18 years old, (ii) discharged home with a diagnosis of upper respiratory tract infection (URTI), pneumonia, acute asthma, or acute exacerbation of chronic obstructive pulmonary disease. Primary outcome was the proportion of patients returning to any ED or walk-in clinic within three and seven days of the index visit. Secondary outcomes were the mean cost of care and the incidence of antibiotic prescription for URTI patients. The cost of care was estimated from the Ministry of Health's perspectives using time-driven activity-based costing.ResultsThe ED group included 170 patients and the walk-in clinic group 326 patients. The return visit incidences at three and seven days were, respectively, 25.9% and 38.2% in the ED vs. 4.9% and 14.7% in the walk-in clinic (adjusted relative risk (arr) of 4.7 (95% CI 2.6-8.6) and 2.7 (1.9-3.9)). The mean cost ($Cdn) of the index visit care was 116.0 (106.3-125.7) in the ED vs. 62.5 (57.7-67.3) in the walk-in clinic (mean difference of 56.4 (45.7-67.1)). Antibiotic prescription for URTI was 5.6% in the ED vs. 24.7% in the walk-in clinic (arr 0.2, 0.01-0.6).ConclusionsThis study is the first in a larger research program to compare the value of care between walk-in clinics and the ED. The potential advantages of walk-in clinics over EDs (lower costs, lower incidence of return visits) for ambulatory patients with respiratory diseases should be considered in healthcare planning.© 2023.
