Critical Care Clinical Trial
Official title:
Improving Providers' Decision-Making and Reducing Information Overload Using Information Visualization in EHRs
This study aims to test the efficacy of an information visualization dashboard on decision-making using a randomized controlled trial with crossover. This study aims to test the efficacy of using an information visualization dashboard on ICU providers' decision-making, efficiency, and performance compared to their institutional EHR through a randomized control trial with crossover.

Primary | Time to Task Completion | To assess the amount of time required to make a decision (i.e., complete a task), participants will be asked to find the answers to clinical questions. | Duration of Single Usability Session, up to 25 minutes | |
Primary | Percent of Successfully Completed EHR Tasks | To measure performance, participants will be scored using the following: 0 points for incorrect response, 0.5 points for partially correct response, and 1 point for correct response. | Duration of Single Usability Session, up to 25 minutes | |
Primary | Time to Case Completion | To measure efficiency, participants' time to complete case review and tasks will be recorded and reported in minutes. | Duration of Single Usability Session, up to 25 minutes | |
Primary | Number of Clicks Per Case | To measure efficiency, participants' number of mouse clicks to complete case review and tasks will be recorded. | Duration of Single Usability Session, up to 25 minutes | |
Primary | Degree of Pupil Constriction | Physiologic fatigue will be measured using eye tracking device to capture changes in pupil size (which represents cognitive fatigue). | Duration of Single Usability Session, up to 25 minutes | |
Primary | System Usability Scale Survey Score | Perceived satisfaction measured using the System Usability Scale survey. Values range from a minimum of 0 to a maximum of 10. Higher scores indicate higher satisfaction (better). It is expected to take 2-3 minutes to complete this survey. | Immediately following each intervention, within approximately 4-5 minutes | |
Secondary | Perceived Workload Score | The NASA-Task Load Index (TLX) measures perceived workload using 6 subscale questions. Scores are reported as an overall total ranging from a minimum of 0 to a maximum of 100. Higher scores indicate higher workload (worse). It is expected to take 1-2 minutes to complete this index. | Immediately following each intervention, within approximately 1-2 minutes | |
Secondary | Number of Eye Fixations on Screen | Information seeking load measures the amount of information being processed by participants using an eye-tracking device to measure fixation points (which represents thought-processing). | Duration of Single Usability Session, up to 25 minutes | |
Secondary | Number of Screens Per Case | To measure efficiency, participants' number of screens visited to complete case review and tasks will be recorded. | Duration of Single Usability Session, up to 25 minutes | |
Secondary | Stress Score | Participants will be asked to rate their current level of stress based pictorial images on a numbered scale ranging from 0 (None) to 10 (Worst possible). | Baseline | |
Secondary | Sleepiness Score | Participants will be asked to rate their current level of sleepiness based pictorial images on a numbered scale ranging from 0 (Wide awake, alert) to 10 (Sleep onset soon, having dreamlike thoughts). | Baseline |
