Preliminary findings from this pilot study demonstrating the feasibility of a dedicated ambulator-assisted physical activity protocol and its potential impact on hospital outcomes will provide the justification for external funding of a larger randomized clinical trial. Lessons learned from the pilot study will allow us to optimize the ambulation protocol and target population for a larger study. Such a study would investigate the effect of the ambulator-assisted physical activity protocol on patient mobility associated health care costs. This work could shift the current paradigm that aggressive mobilization is reserved for post-acute care settings and could serve as a model for improving the value of care provided to elderly patients in acute care facilities.
