This project was originally funded in order to conduct a multicenter, randomized controlled trial to determine whether early ICU rehabilitation, for Burn Intensive Care Unit BICU patients, would decrease hospital length of stay. The original protocol specified fifty subjects to be randomized at each of three sites for a total of 150 subjects. After twenty-three study subjects had been enrolled and the outpatient phase of testing was instituted, new data from a similar study was published in a medical ICU population that caused great discussion across the investigators. The results of that study in combination with the patient care delivery pattern within the original design of this study caused a shift in focus of this study. The original study was deemed phase I and closed. The second phase proposed to examine medical records within a large national hospital database to identify optimal care delivery patters. Minimizing the duration of immobilization of patients and developing strategies to lessen its impact are the goals of the second phase.
