Providing clinicians with problem-based access to knowledge: troubleshooting pulmonary artery catheter waveforms

Area of Science:

• Critical Care Medicine
• Medical Informatics
• Cardiovascular Monitoring

Background:

• Pulmonary artery (PA) catheter waveform interpretation is crucial for patient management in intensive care units.
• Clinicians require efficient access to expert knowledge for accurate troubleshooting.
• Existing methods for PA waveform analysis may lack user-friendly, visually-supported guidance.

Purpose of the Study:

• To describe a microcomputer system designed for computer-based expert knowledge access.
• To facilitate troubleshooting of pulmonary artery (PA) catheter waveforms.
• To evaluate the system's impact on clinical practice and cost-effectiveness.

Main Methods:

• Development of a microcomputer system with problem-focused knowledge access.
• Integration of extensive graphics and images to illustrate PA catheter waveform concepts.
• Implementation in an 18-bed medical intensive care unit for use by nurses and physicians.

Main Results:

• The system provides problem-focused access to expert knowledge on PA catheter waveforms.
• Extensive use of graphics and images enhances knowledge explication.
• The system is utilized by both nurses and physicians in a medical intensive care unit setting.

Conclusions:

• The developed system offers a novel approach to PA catheter waveform troubleshooting.
• Visual and problem-focused knowledge delivery can aid clinical decision-making.
• Further evaluation is ongoing to assess the system's impact on knowledge, skills, satisfaction, and costs.
