 Plan This 4-year project will be a randomized controlled trial of a multidisciplinary-multicomponent intervention to improve OH in patients admitted to Nursing Home NH and rehabilitation settings. During the 37-month enrollment period, the investigators expect to consent 350 subjects who will be randomized into intervention and control groups 175 subjects each. During their stay, subjects in the intervention group will receive a standardized treatment for their OH, or to prevent OH, while those in the control group will receive usual care. The investigators expect that 85 will remain in the study until they are discharged from the NHrehabilitation unit. Following discharge, the investigators will conduct weekly phone calls to monitor incidence of falls for one month. Subsequently, at 12-months post-discharge, the investigators will conduct a chart review, and the study will terminate. The investigators expect 85 of the subjects discharged from the NHrehabilitation unit that were enrolled in the study will remain in the study at 12-months post discharge. The investigators performed a pilot study on up to 10 subjects while waiting for adequate staffing to conduct the study with blinded data collectors.
