Preventing Frailty in Hospital Through Mobilizing

Frailty describes the variability in aging and explains why two people of the same chronological age may look very different. Higher frailty leads to poor quality of life, disability, and death. Hospitalized patients living with frailty have a higher risk for functional decline, new impairments in activities of daily living, a longer hospital stay, hospital readmission, and death. A previous study from our team has reported that 60% of inpatients have more difficulty with 1+ basic activity of daily living (i.e., eating, getting out of bed, using the toilet, etc.) after hospitalization compared to pre-admission, with 1-in-4 patients having difficulty with 3+ basic tasks. Patients with few health deficits can recover to their pre-admission level, but those with higher frailty levels cannot, priming them for readmissions. Physical activity and reducing time spent sitting or lying postures prevent and improve frailty. Older patients who walk at least once/day outside their room during hospitalization have \~1.7 days shorter length of hospital stay compared with those who stayed in their room. Although multiple barriers exist to promoting upright time in a hospital, strategies that help address patients' excessive time spent in bed are often not implemented but could attenuate the development of frailty in the hospital. Few exercise interventions in hospital studies have considered frailty. The investigators have conducted a clinical trial within the Halifax Infirmary (Nova Scotia Health) that focused on mobilizing patients (average age: \~75 years) via regular visits by a Kinesiologist and observed that the intervention groups reduced their frailty level from preadmission and admission versus discharge. While preliminary findings from this model were promising, its reach was limited to acute geriatric care and dependent upon researchers to conduct the intervention. At the Georges-L. Dumont hospital, a patient mobilization program has been introduced in General and Internal Medicine (floor 4C) that embedded Kinesiologists within care to visit patients daily. Preliminary findings indicate that patients and staff are enjoying the program via self-report questionnaire. However, evaluations of the program's effectiveness in changing objectively measured activity and frailty levels and whether multiple patient visits would be more effective (e.g., refining the program) are unclear. The investigators propose to evaluate the effectiveness of the existing patient mobilization program and if more patient contact improves outcomes. Our study integrates activity monitoring technology and frailty assessments to help patients leave the hospital healthier and decrease the risk of readmission. Study Objectives: The proposed study will test the hypothesis that, compared to usual care (Kinesiology visit once/day), patients who receive multiple check-ins will, 1) increase their step counts and upright time, 2) decrease their frailty level, and 3) have a less length of stay and less readmission rates.
