Abstract
BACKGROUND: Hospital at Home (HaH) is a growing care model requiring significant investments. Critical to starting a program is estimating census and enrollments. The objective of this study was to compare expected versus actual consults, enrollments, and barriers in a novel HaH program. METHODS: This was an observational, retrospective cohort study at a single urban academic medical center. Adult inpatients considered for enrollment to HaH were included. Demographic data, diagnoses and outcomes data were extracted for HaH patients. Volume and outcomes of HaH consults were recorded, including reasons for ineligibility or a patient declining to enroll. RESULTS: Over the first year of implementation, 248 patients enrolled. The average daily census (ADC) grew over months 1-6, then plateaued at a mean of 4.4 patients during month 10, with an overall ADC range from 0 to 7 patients. From months 7 to 12, there were 724 consults for a home hospital assessment, of which 22.5% (163/724) of patients were enrolled, 21.8% (158/724) declined to enroll, 29.3% (212/724) were ineligible for the program, and 26.4% (191/724) had consults that were deferred until the time of discharge and never explicitly consented or refused. The most common reasons for program ineligibility were complex care needs, insurance status, and not meeting inpatient status. The most common reasons patients declined to enroll were a preference to remain in the brick-and-mortar hospital and home conditions not suitable for HaH. CONCLUSIONS: This retrospective, cohort study defines the challenges of enrolling patients in an HaH program and provides areas for other programs to examine as they start or grow a program.
