ROBot assisted physical training of older patients during acUte hospitaliSaTion (ROBUST)
– a randomised controlled trial
Introduction: Inactivity during hospitalisation is associated with significant risk of functional decline especially in older patients. This have major impact on the individual level due to decreased wellbeing and higher level of dependency and on the society level due to increased caregiver burden following hospital discharge. This study aims to address if robot assisted physical training can prevent functional decline during acute hospitalisation in older geriatric patients.
Methods: ROBUST is a blinded RCT. Patients (n = 488) admitted with acute medical illness to Department of Geriatric Medicine, Odense University Hospital will be randomised to usual care and robot assisted active strength training twice daily (intervention group) or usual care and robot assisted passive sham training (control group) until discharge. Both groups will receive protein supplements Inclusion criteria: ≥65 years of age, able to ambulate before hospitalisation, expected length of stay ≥2 days. Exclusion criteria: Able to ambulate without assistance during current hospitalisation, severe dementia, delirium, conditions contradicting robot training. The primary outcome, functional decline, will be assessed by Barthel-Index and 30s chair stand test. Secondary outcomes include Quality of life (EQ-5D), Geriatric Depression Scale, Fear of falling (FES-I), cognition (MMSE), qualitative interviews, falls, caregiver burden, discharge destination, readmissions, healthcare costs, sarcopenia, and mortality. Outcomes will be assessed at admission, discharge, and one- and three months follow-up. Data on comorbidity, medications, blood samples, and clinical frailty scale will be collected.
Discussion: This study will investigate the effects of in-hospital robot assisted strength training on functional status in older patients with multimorbidity.
