Preventing Frailty in Hospital Through Mobilizing Patients: A Pilot RCT


Older adults who live with frailty are characterized by chronic illness and are vulnerable population. Most hospital inpatients have higher frailty levels and spend their day in a sitting or lying posture. This inactivity increases their risk of more health problems and possible readmissions. Movement os one of the best medicines for preventing and improving frailty levels. We propose a pilot randomized clinical trial that tests the effectiveness of a Kinesiologist-led mobility program in hospital to help patients reduce their time in bed, frailty level, and shorten their length of stay. Patients within Vitalité will be randomized to receive daily visits from a Kinesiologist (Usual Care for 4C n=30) or receive multiple daily visits (n=30) for the duration of their hospital stay. Physical activity and postures will be measured via accelerometers (activPAL 24-hr/day) and frailty via a validated questionnaire from the Canadian Longitudinal Study on Aging, Length of Stay and rates of readmission will be recorded. This pilot study is necessary to determine if this model should be up scaled and expanded to other settings. If successful, the mobility intervention will help patients move more and prevent the deconditioning often observed with hospitalization that is responsible for making patients frailer.


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 decreased length of stay and re-admission rates.
