Outline Describe STRIDE program Report results of initial evaluation Program goals Eligibility criteria Staff roles Report results of initial evaluation Baseline patient characteristics Outcomes: hospital length of stay, inpatient falls, discharge destination, and ED visits and readmissions within 30 days of discharge
Clinical Problem Hospitalized older adults spend only 3% of their time standing or walking <5% have physician orders for bed rest Immobility during hospitalization has many negative physical effects: loss of muscle mass, deconditioning, overall weakness Poor physical function associated with adverse outcomes falls, delirium, longer hospital stays, higher rates of discharge to skilled nursing facilities and readmission Covinsky JAMA 2011 306(16); Kommuri Arch Med Res 2010 41(5); Zisberg JAGS 2011 59(2); Brown JAGS 2009 57(9); Murphy Arch Int Med 2011 171(3)
Objectives To optimize the physical function of older Veterans by increasing the amount of time spent walking during their hospitalization Key program features Proactive, no baseline functional deficits required Early assessment, ideally within 24 hours of admission Supervised walking, up to 20 minutes daily until discharge
Targeted gait and balance assessment STRIDE Patient Flow TARGET POPULATION Patients > 60 admitted to medical service referred by treating physician NOT ELIGIBLE Chest pain or angina Admitted from nursing home New neurological deficit Surgery planned Bedrest order Unable to follow 1 step command Non-ambulatory Targeted gait and balance assessment Performed by Physical Therapist NO YES Safe for STRIDE? Usual Care STRIDE Program 1-2 walks daily for duration of hospitalization supervised by Recreation Therapy Assistant
STRIDE Staff Roles Physical Therapist Screens consults Performs baseline balance and gait assessment Recommends assistive devices and/or gait belt if needed Identifies activity goals with patients
STRIDE Staff Roles Recreation Therapy Assistant Works with Nursing to plan timing of daily walks Supervises walks for safety Reviews activity goals Provides motivation and encouragement

At least some difficulty or could not do Assistive device – canes 58% Anxious or worried you might fall, past 12 months Ostir, Arch Int Med 2012 – community dwelling, admitted to ACE unit, no confusion, no “tethers”, the mean (SD) gait speed for patients who completed the gait speed walk was 0.53 (0.25) m/s. Blankenburg, Clin Respir J. 2012 Jul 23. – 6 min walk distance in elderly COPD patients 97 meters at admission (little less than double the 58 meters we observed for 2 min test); heart failure patients, the median distance walked on the 6MWT was 213 m (J Card Fail. 2009 Mar;15(2):130-5.

STRIDE Summary STRIDE is safe and well-tolerated by older Veterans hospitalized for medical illness. Program participants had reduced length of stay, fewer SNF admissions for short-term rehab, and no increase in post-discharge acute utilization. STRIDE is a promising interdisciplinary approach to promoting mobility and improving outcomes among hospitalized older adults.
STRIDE Next Steps Expand program evaluation STRIDE@HOME (PI Peterson) Program participants to date, n=274 Patient and provider feedback STRIDE@HOME (PI Peterson) funded by Office of Geriatrics and Extended Care (558-4) Future research questions Optimal “dose” of walking, in terms of total minutes, number of sessions/day, distance. Understand effects of walking program/ disentangle reasons for reduced LOS: physiologic versus impact on providers
