Functional recovery in the elderly after major surgery: Assessment of mobility recovery using wireless technology

Purpose Hospitalization and surgery in older patients often leads to a loss of strength, mobility, and functional capacity. We tested the hypothesis that wireless accelerometry could be used to measure mobility during hospital recovery after cardiac surgery. Description We used an off-the-shelf fitness monitor to measure daily mobility in patients after surgery. Data were transmitted wirelessly, aggregated, and configured onto a provider-viewable dashboard. Evaluation Wireless monitoring of mobility after major surgery was easy and practical. There was a significant relationship between the number of steps taken in the early recovery period, length of stay, and dismissal disposition. Conclusions Wireless monitoring of mobility after major surgery creates an opportunity for early identification and intervention in individual patients and could serve as a tool to evaluate and improve the process of care and to affect postdischarge outcomes.
