BACKGROUND: Rapid qualitative assessment was used to describe early strategies to implement an evidence-based walking program for hospitalized older adults, assiSTed eaRly mobIlity for hospitalizeD older vEterans (STRIDE), mandated by a regional Department of Veterans Affairs health care system office (Veterans Integrated Service Network [VISN]). METHODS: Data were collected from 6 hospital sites via semistructured interviews with key informants, observations of telephone-based technical assistance, and review of VISN-requested program documents (eg, initial implementation plans). An overarching framework of actionable feedback for VISN leadership and specification of locally initiated implementation strategies, using the Expert Recommendations for Implementing Change (ERIC) compilation, was used. Actionable feedback was shared with VISN leadership 1 month after the initiative. RESULTS: ERIC implementation strategies identified were as follows: (1) promoting adaptability-4 sites had physical therapists/kinesiotherapists instead of assistants walk patients; (2) promoting network weaving-strengthening nursing and PT/KT partnership with regular communication opportunities or a point person was important for implementation; (3) distributing educational materials-2 sites distributed information about STRIDE via e-mail and in person; and (4) organizing clinician implementation team meetings-3 sites used interdisciplinary team meetings to communicate with the clinical staff about STRIDE. CONCLUSION: This qualitative study sheds light on early experiences with implementing STRIDE; the results have been instructive for ongoing implementation and future dissemination of STRIDE, and the approach can be applied across contexts to inform implementation of other programs.
