Wearable Technology for Hospital Inpatients

Study Overview
=================
Brief Summary
-----------------
This study will address the feasibility of using wrist-worn fitness trackers to monitor hospital inpatients. The study is being conducted in the Intensive Care Unit where patients are closely monitored, in order to provide gold standard measurements of heart rate, and accurate estimates of sleep quality.

Detailed Description
-----------------
Overall Hypothesis: The use of wearable personal fitness trackers to monitor physiologic signals in hospital inpatients is feasible, reliable, secure, and cost effective. Specific Objectives: To evaluate the feasibility of applying a wrist-worn personal fitness tracker to hospital inpatients for the purpose of monitoring heart rate and sleep quality during the night. To determine the accuracy and completeness of high-frequency heart rate measurements recorded from personal fitness trackers in hospital inpatients. To compare measurements of sleep quality generated by personal fitness trackers with clinical assessments by nursing staff among hospital inpatients. To develop a workflow and data analysis pipeline for downloading, storing, analyzing, and visualizing data generated by personal fitness trackers worn by hospital inpatients. To evaluate the feasibility of a larger prospective multicenter trial examining the utility of personal fitness trackers among hospital inpatients, including recruitment rates, inclusion/exclusion criteria, data management protocols, and outcomes measures.
