Understanding infusion administration in the ICU through Distributed Cognition.

Area of Science:

• Healthcare Technology
• Human Factors Engineering
• Cognitive Science

Background:

• Evaluating healthcare technologies requires understanding real-world use.
• Distributed Cognition (DC) offers a theoretical framework for this evaluation.
• The Distributed Cognition for Teamwork (DiCoT) methodology operationalizes DC for team-based studies.

Purpose of the Study:

• To apply the DiCoT methodology to investigate nurses' use of infusion pumps in an Intensive Care Unit (ICU).
• To identify how cognition is distributed among nurses, the physical environment, and technological artifacts during infusion pump use.
• To explore potential improvements in safety and efficiency based on the DiCoT analysis.

Main Methods:

• Ethnographic observations and interviews were conducted with nurses in an ICU setting.
• The DiCoT methodology was employed for data analysis.
• Representational models were constructed, focusing on information flow, physical layout, social structures, and artifacts.

Main Results:

• Cognition was found to be significantly distributed within the ICU environment.
• Distribution occurred socially among nurses, physically through the material environment, and via technological artifacts.
• The study identified specific areas where nurses' interactions with infusion technology could be enhanced.

Conclusions:

• The DiCoT methodology effectively facilitated the study of complex healthcare technology use.
• Understanding the distributed nature of cognition is crucial for optimizing healthcare practices.
• The findings provide a basis for improving the safety and efficiency of infusion pump use in ICUs.
