Importance of early consideration of scaling and sustainability for aging‐related care models: Case study of Hospital at Home

Abstract

AbstractFor aging‐related research, there is a pressing need to attend to the dissemination and implementation of evidence‐based interventions. Some aging‐related interventions with established effectiveness may be poorly disseminated and implemented due to behavioral, organizational, payment, or other constraints. To provide insight into the beginning to end process of translation and implementation, we present a case history of the three‐decade progression of Hospital at Home (HaH) now nearing national dissemination. We summarize research at various phases with particular attention to implementation considerations. Reviewing over three decades of HaH‐related research dating from initial discovery to translation and implementation, we found that the content and importance of different constructs (e.g., inner practice vs. outer environmental setting) and the choice of implementation strategies differed depending on implementation context (testing of effectiveness, scaling, or sustainability). Early effectiveness studies mostly examined implementation issues related to the intervention, the practice setting, and the individuals involved. However, explicit and early consideration of scale and sustainment was not the primary focus. For example, HaH program intake is primarily through hospital emergency departments (ED). Initial efforts would have benefited from incorporating strategies (e.g., incorporating ED leadership into program leadership) to address night and weekend admissions. Many regulatory barriers did not surface during initial considerations. Considering implementation issues late may contribute to delay in bringing discoveries to population impact. The experience with HaH suggests that scale and sustainability bear earlier consideration because barriers and facilitators to implementation are likely to be different in content and importance at different phases of implementation.
