Quantifying Activity Using Wireless Wearable Technology
Study Details
Study Description
Brief Summary
Wireless wearable devices (WWD) have been shown to be an effective means to measure patient activity and sleep-wake cycles in the ICU. However, no current studies involving WWD have demonstrated the ability of these devices to measure adverse outcomes, including delirium in critically ill patients. This study is unique because the investigators will implement monitoring with the WWD prior to extubation in the ICU to correctly measure first mobilization, as well as capture quality of sleep and episodes of delirium for the first five postoperative days.

Detailed Description
In this single-center non-randomized prospective cohort study, cardiac surgical patients undergoing cardiac surgery with cardiopulmonary bypass will be enrolled consecutively with written informed consent from the time this protocol is approved by the IRB until 100 subjects are enrolled (expected duration of subject enrollment is 12 months). Upon arrival into the ICU, cardiac surgery subjects will have a Fitbit Charge 2 device placed on their wrist and will wear the device until the fifth post-operative day. This device will wirelessly transmit data regarding activity and sleep quality to a smartphone application for the duration of wear. No identifiable patient information will be entered into the smartphone application or transmitted to any external entity.

Outcome Measures
Primary Outcome Measures
- Number of steps walked [Postoperative day 2 to Postoperative day 5]
Number of steps walked as measured by the Wireless Wearable Device
Secondary Outcome Measures
