This pilot study will enable the investigators to identify which patients would tolerate the intervention and what degree of participation would be meaningful to improve the outcomes measured. The study will begin by enrolling patients with 6-Clicks scores of 16-20, as these patients will experience the greatest benefit from an ambulation protocol. At present, such patients do not receive any PT intervention and ambulation by nurses occurs only sporadically as time allows. Additionally, the pilot will help to bring clarity to the direct impact of aggressive mobilization of medical inpatients on important outcomes that are directly tied to healthcare cost. Results of this work will inform feasibility and power calculations for a larger randomized trial. Results of that trial could directly impact the approach to the medical inpatient in terms of prioritizing and resourcing mobilization strategies.
