Evaluation of Information Displays A Paper & Pencil, Computer, Simulator, and ICU Based Study
An observational study of Healthy, run by University of Utah.
Trial summary
Our objective is to develop intuitive, meaningful and ergonomically efficient informative displays specific to the user's domain. Specifically we aim to enhance and refine the display prototype of ABG information to include gas-exchange, acid-base balance, lung mechanics, ventilation, oxygenation, and metabolism… Read more about this study

About this study

Read the detailed description
To create an intuitive and meaningful visualization of Arterial Blood Gas (ABG) variables, it is necessary to address usability, ergonomics, domain specific, and expertise specific issues and concerns. Our objective is to develop intuitive, meaningful and ergonomically efficient informative displays specific to the user's domain. Specifically we aim to enhance and refine the display prototype of ABG information to include gas-exchange, acid-base balance, lung mechanics, ventilation, oxygenation, and metabolism information.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
New ICU Display VisualizationBehavioural
| Study group | Role | What they receive |
|---|---|---|
| Simulator Group - With Display | ICU nurses who viewed the new ICU display visualization Receives: Behavioral: New ICU Display Visualization | |
| Simulator Group - Without Display | ICU nurses who did not view the new ICU display visualization, but instead viewed a traditional "spreadsheet" style presentation of ICU trends of data |
What is being measured
The primary outcome is the main question the study is designed to answer.
Nurses using the new ICU display will detect and communicate to an attending physician (confederate) more abnormal patient physiological states than when using the tabular (control) display.
Measured: At time of observation

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy, run by University of Utah.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Nurses using the new ICU display will detect and communicate to an attending physician (confederate) more abnormal patient physiological states than when using the tabular (control) display. (time frame: At time of observation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2014; AzTrials last refreshed its copy on 6 Nov 2026.
