Evaluation of Information Displays A Paper & Pencil, Computer, Simulator, and ICU Based Study

December 11, 2014 updated by: Noah Syroid, University of Utah
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.

Conditions

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.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Simulator Group - With Display
ICU nurses who viewed the 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 the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
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
