Computerized blood gas interpretation as tool for classroom and ICU

Area of Science:

• Medical Informatics
• Clinical Education
• Critical Care Medicine

Background:

• Effective interpretation of arterial blood gas (ABG) results is crucial for patient management in intensive care units (ICUs).
• Nurses require specialized knowledge for accurate ABG analysis and timely clinical decision-making.
• Existing educational tools may not fully meet the needs of critical care nurses for continuous learning and support.

Purpose of the Study:

• To introduce the structure and function of a PC-based blood gas interpretation program, ABG-consultant.
• To evaluate the educational impact of the ABG-consultant on ICU nurses' knowledge.
• To assess user acceptance and satisfaction with the ABG-consultant program.

Main Methods:

• A prospective, blinded study was conducted in an interdisciplinary ICU.
• Specialized ICU nurses were exposed to the ABG-consultant program.
• Knowledge assessment involved pre- and post-exposure written examinations, with one group using the ABG-consultant and a control group not.

Main Results:

• Nurses using the ABG-consultant showed a significant increase in examination scores (4.8 points, p < 0.0001).
• The control group showed a minimal, non-significant increase in scores (1.3 points, p < 0.16).
• Over 400 consultations were performed, with users reporting the system as helpful and easy to use.

Conclusions:

• The ABG-consultant program effectively enhanced the blood gas interpretation knowledge of ICU nurses.
• The findings support the use of similar computer-based teaching-consulting approaches in other clinical domains.
• The program's user acceptance suggests potential for broader application in medical education and practice.
