Abstract

OBJECTIVES: To compare noninvasive mobility sensor patient motion signature to direct observations by physicians and nurses. DESIGN: Prospective, observational study. SETTING: Academic hospital surgical ICU. PATIENTS AND MEASUREMENTS: A total of 2,426 1-minute clips from six ICU patients (development dataset) and 4,824 1-minute clips from five patients (test dataset).None. MAIN RESULTS: Noninvasive mobility sensor achieved a minute-level accuracy of 94.2% (2,138/2,272) and an hour-level accuracy of 81.4% (70/86). CONCLUSIONS: The automated noninvasive mobility sensor system represents a significant departure from current manual measurement and reporting used in clinical care, lowering the burden of measurement and documentation on caregivers.
