Purpose:

Low mobility, defined as being limited to bed or chair, is common during acute hospitalization. This study will evaluate the impact and safety of a hospital walking program for older patients during acute general medical hospitalization. Participants who are 65 years of age or older, will be randomized to usual care (UC) or to a hospital walking program (WP), which includes twice daily walks with assistance, provision of necessary ambulatory devices, and a behavioral intervention strategy designed to encourage out of bed activity. Throughout hospitalization, the WP and UC veterans will were wireless monitors on the thigh and ankle that measure activity. The primary goal will be in increase the length of time veterans spend out of bed and to assure this out of bed activity is safe.


Study summary:

Background: Low mobility, defined as being limited to bed or chair, is common during acute hospitalization. The candidate's work has demonstrated low mobility to be associated with adverse outcomes including functional decline, need for new nursing home admission, and death even after controlling for illness severity and comorbidity. Objective: Using a Phase II trial design, the impact and safety of a hospital walking program for older patients during acute general medical hospitalization will be evaluated. Project Design: 100 patients, age 65 years admitted to the medical wards at the Birmingham VAMC will be recruited within 48 hours of hospitalization and followed for 14 days after enrollment or until discharge, which ever comes first. Exclusion criteria will include: (1) Delirious based on positive Confusion Assessment Method (CAM); (2) Mini Mental State Examination Score < 17; (3) Patient on isolation; (4) Inability to ambulate 2 weeks prior to admission; (5) Having a medical diagnosis deemed by the primary physician to be a contraindication to ambulation; (6) patient with an imminently terminal illness; and (7) Non-English speaking. Participants will be randomized to either usual care (UC) or to a hospital walking program (WP), which includes twice daily walks with assistance, provision of necessary ambulatory devices, and a behavioral intervention strategy designed to encourage out of bed activity. Throughout hospitalization, the WP and UC veterans will wear on the ipsilateral thigh and ankle wireless monitors that measure horizontal and vertical orientation with respect to gravity. Previously validated by the candidate to assess levels of mobility during hospitalization, the output will be used to calculate the length of time patients spent lying, sitting, and standing or walking, using pre-defined criteria. Other daily measures will include orthostatic blood pressure, functional assessments, and assessment of falls and symptoms over the previous 24-hours. The primary outcome measure is time out of bed as measured by the wireless monitors. Importantly, our goal is to assess not only the amount of mobility that occurred as a result of the hospital walking program but that which occurred beyond the intervention. In our previous VA-funded study, patients spent an average of 17.1% or 4.1 hours out of bed per 24-hour period of time (s.d. 2.9). Our goal is to increase this by 50% or 2 hours to an average of 6.1 hours. This results in an effect size of 0.69 standard deviation units. A sample size of 45 per group provides 90% power to detect this 2-hour difference in the amount of time patients spend out of bed at the = .05 level. Significance: at present there is a paucity of data regarding the impact or safety of a hospital walking program for general medical patients. Results of this study will enable researchers to determine the safety and efficacy of the walking program for older veterans during hospitalization and will provide information regarding effect size for a definitive intervention trial.
