Physical Activity in Geriatric Patients Before and After the Introduction of a Staff-facing Real-time Activity Screen and Validation of the Danish Version of the Acute Care Mobility Assessment - a Hybrid Implementation and Effectiveness Study in Two Patient Cohorts

The study uses a Hybrid Type I design in which both the implementation of a staff-facing screen and the effectiveness on physical activity will be evaluated. The study is conducted in two phases.

Phase one is an observational cohort study. During 6 weeks, 24-hour activity will be assessed in all patients (65+) admitted to a geriatric ward in Denmark, who are able to walk and to provide informed consent (or vicarious consent). Activity will be measured for a maximum of 7 days. Demographic characteristics will be collected (sex, age, place of residence, comorbidities, admission diagnosis, civil status, frailty), and the patients will be asked about their: daily activities, walking ability, life space activity, present activity, use of walking aids, and falls. On inclusion, the patients will be assessed for their basic mobility, cognition, gait speed, and their level of mobility. The Acute Care Mobility Assessment will be validated on the initial 5-10 patients via cognitive debriefing interviews (May-July 2024). In the same period, an ethnographic field study will be conducted with focus on physical activity followed by semi-structured interviews (N=17) with managers and health care professionals.

In the follow-up study, we will assess in-hospital physical activity over a 6-week period after introducing a staff-facing activity screen, showing real-time activity and to investigate whether the activity screen increases physical activity among hospitalized geriatric patients. 24-hours physical activity will be re-quantified using SENS motion ®, sensor technology. The study design will otherwise follow the same approach as the initial study, including the use of the same outcome measures. In the same period, we will repeat the ethnographic field study and interviews regarding focus on physical activity and implementation of the activity screen with managers and health care professionals inspired by Making Every Contact Count. The Consolidated Framework for Implementation Research (CFIR) will be used as Framework, and focus will be on adoption and adaptation.

The study meets the guidelines of the Declaration of Helsinki and is approved by the Research Ethics Committee (F-24023831).
