Program Failure of an Integrated Emergency Department/Hospital-at-Home Model for Common Acute Infections: Exploratory Findings in a Multicenter Retrospective Cohort Study

Sponsor: Chimei Medical Center

Summary

This is a retrospective, multicenter, non-interventional cohort study based on data derived from existing electronic medical records. The study collects data on patient demographic and clinical characteristics, infection diagnosis, triage vital signs, laboratory values, and comorbidities in adults enrolled in the Emergency Department-initiated Hospital-at-Home (ED/HaH) model under Taiwan's National Health Insurance Administration (NHIA) Acute Care at Home (ACAH) Pilot Program. For patient selection, enrollment in the NHIA ACAH Model C pathway was used as the index event. The patient selection period extends from August 1, 2024 to January 1, 2026. All adult patients (aged ≥18 years) with a primary diagnosis of pneumonia, urinary tract infection (UTI), or skin and soft tissue infection (SSTI) - confirmed by ICD-10 codes - who were enrolled directly from the emergency department at one of three participating tertiary medical centers (Chi-Mei Medical Center, Wan-Fang Hospital, and Taipei Medical University Hospital) during that period were considered for inclusion. Patients were identified through electronic medical record queries, and data were abstracted using a standardized case record form applied uniformly across all sites. The primary outcome is HaH program failure, defined as any unanticipated care escalation (emergency department transfer, inpatient admission, or ICU admission within 48 hours of ED transfer) or death occurring during the HaH episode prior to planned completion. The program failure rate and characteristics of failure events - including failure type, clinical disposition, and time from HaH initiation to failure - will be described. As a secondary objective, exploratory multivariable analysis will examine whether demographic and clinical variables measured at ED enrollment show potential associations with program failure. A total of 472 HaH episodes from 420 unique patients were analyzed. Statistical analyses will be performed for the overall cohort.
