Impact of self-directed exercise intervention in a minority rich, hematopoietic stem cell transplant (HSCT) inpatient population at high risk for sarcopenia and falls.

Abstract

390 Background: Extended hospitalizations in the adult HSCT population increase patients’ risk for deconditioning and sarcopenia. Sarcopenia negatively impacts overall survival in adult HSCT patients (Armenian et al, 2019) and is strongly associated with falls among older adults (Yeung et al, 2019; Marques A & Queirós C., 2018; Wheatley et al, 2021). Methods: In a safety net, minority rich, academic medical center in suburban NYC, stationary pedals were placed inside patient rooms in a 31-bedded inpatient HSCT unit starting Q4 2020. Intentional, inpatient room placement prevented additional risk of infectious exposures to COVID-19 in late 2020-2021, allowed for safe access to pedals from a seated position in chairs inside patient rooms, and provided insight into self-directed exercise participation. Attending MDs, PAs and RNs encourage HSCT patients to utilize stationary pedals up to 3 times daily, while usage remains self-directed. Direct observation of patient pedal usage and patient-verbalized interest in participation reflects positive acceptance and consistent usage since implementation. Results: 2019-2023 Midas Event Reporting data was reviewed by the author. Total numbers of Weak/Impaired Gait patient falls decreased in the post-implementation period: 19 falls at baseline versus 13 falls in 2021, 11 falls in 2022, and 3 falls in Q1 2023. Pre-intervention 2019 data indicates 63.3% of falls are among Weak/Impaired Gait patients. (2020 falls data is not included due to unit closures during the COVID-19 pandemic). Post-intervention 2021-2023 data reveals a mean of 51.2% of falls are in Weak/Impaired Gait patients, indicating a 12.1% decline in falls in the post-intervention period of 2.25 years. Conclusions: Sarcopenia and inpatient falls impact patient outcomes (i.e., injuries, extended hospitalizations, and survival) and are financially burdensome. Each inpatient fall, whether injurious or not, costs hospitals approximately 35,000 (Dykes et al, 2023). Reductions in numbers of inpatient falls at this institution are potentially associated with the following hospital cost savings: 210K in 2021, 280K in 2022 and a projected 245K in 2023. Reduction in sarcopenia during extended hospitalizations, when reviewed alongside the financial impact of inpatient falls, supports the ongoing implementation of self-directed exercises in this population. Next steps include self-directed use of resistance bands, chair-based and bed-based stretches, and utilizing self-tracking devices to record exercise duration.
