Quantifying Activity Using Wireless Wearable Technology

An observational study in Activity, Motor, Sleep and Delirium, sponsored by University of Texas Southwestern Medical Center. Completed at 1 site in United States. Open to participants aged 18 Years to 100 Years. Per ClinicalTrials.gov, last updated 2019-10-03.

Primary conditionDeliriumRegistry: Motor ActivityReclassifiedWhy we changed it
Registry
Motor Activity — the first condition term the registry derived for this study.
ClinicalTrials.gg
Delirium
Why
  1. Motor Activity is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Delirium.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study 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.

Read the 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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2017 to primary completion in Aug 2019, 28 months.

Of 176 non-industry observational studies under Delirium, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 37. This study's 28 months is above that.

Counting every sponsor, half of 178 studies reached it within 20 months; a quarter within 11 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 3, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
