Effectiveness of Direct Admission Compared to Admission Through the Emergency Department: A Stepped-Wedge Cluster-Randomized Trial.

Abstract

Direct admission (DA) to hospital can reduce emergency department (ED) utilization by bypassing the ED during the admission process. We implemented a DA program across 3 health systems and compared timeliness of care, family experience of care, and post-admission clinical deterioration among children admitted via DA versus the ED after their clinic was randomized to begin the DA program. Using a stepped-wedge design, 69 primary and urgent care clinics were randomized to 1 of 4 time points to begin a voluntary DA program, February 1, 2020 to April 30, 2023. Outcomes in children <18 years admitted with 7 common medical diagnoses were compared using adjusted logistic or linear regression. A total of 2599 children were admitted with eligible diagnoses during the study period , including 145 children admitted directly and 1852 admitted through EDs after program implementation at their clinic. Median age was 2.8 (interquartile range: 1.1-6.8) years, 994 (49.8%) were female, and 1324 (66.3%) were Medicaid-insured. Adjusted regression analyses showed that if each child was admitted via DA versus the ED, average time to initial clinical assessment was 3.1 minute (95% confidence interval: 1.7-4.5) slower, whereas time to initial therapeutic management was 49.6 minutes faster on average (95% confidence interval: 30.3.2-68.9). There were no significant differences in time to initial diagnostic testing or rates of post-admission clinical deterioration. Compared with ED admission, DA appears equally safe and acceptable to families, and may be associated with a significantly shorter time to initial therapeutic management with modestly longer time to initial clinical assessment.
