BackgroundEarly‐supported discharge (ESD) hospital‐at‐home (HaH) programs facilitate hospitalized patients to receive ongoing acute‐level care at home, thereby promoting patient‐centeredness while improving hospital throughput.ObjectivesThe current study aimed to test multiple implementation strategies to increase and sustain HaH ESD utilization.MethodsWe conducted interrupted time series analyses to evaluate the effectiveness of implementation strategies on weekly HaH ESD referrals and capacity utilization at five hospitals. Intervention 1 included provider‐focused education and HaH nurse navigator support (July 2021 to May 2022). Intervention 2 added provider‐level referral performance feedback and daily electronic health record‐based eligibility reports (May 2022 to December 2022). During postintervention (January 2023 to June 2023), implementation strategies were no longer supported by the study team. Clinical outcomes were assessed over time and between patient subgroups.ResultsThere were 5951 HaH ESD patients overall. After Intervention 2, we observed immediate increases in weekly HaH ESD referrals (level change mean difference [MD, 95% confidence interval]: 14.8, 5.9–23.6) and capacity utilization (level change MD: 13.9%, 6.2%–21.5%) and additional week‐to‐week increases in capacity utilization (slope change MD: 0.6%, 0.2%–0.9%), compared to Intervention 1 trends. HaH ESD referrals and capacity utilization were sustained postintervention. The proportion of provider‐initiated referrals increased over time (Intervention 1: 79.4%, Intervention 2: 90.9%, postintervention: 95.2%). As HaH ESD utilization increased, we observed shorter inpatient length of stay and fewer HaH ESD encounters per visit (p < 0.01). There were small, statistically significant differences in 30‐day mortality and readmission for residents of rural and socioeconomically disadvantaged areas.ConclusionApplying referral‐focused provider feedback and daily eligibility reports were effective within a multicomponent approach to increase and sustain HaH ESD utilization.
