Evaluation of a Measurement System to Assess ICU Team Performance

Area of Science:

• Healthcare quality and safety
• Team dynamics in critical care settings
• Measurement and evaluation of clinical teamwork

Background:

• Effective teamwork is crucial in critical care environments.
• Existing observational systems for measuring teamwork in ICUs are limited.
• Accurate assessment of teamwork is needed to improve patient outcomes.

Purpose of the Study:

• To evaluate the reliability and validity of a novel behavioral marker system for assessing teamwork in intensive care units (ICUs).
• To provide a tool for objective measurement of teamwork behaviors in critical care.

Main Methods:

• Observed 138 instances of teamwork across multidisciplinary rounds, nurse handoffs, and simulated codes.
• Utilized two raters to assess teamwork using a behavioral marker system.
• Calculated interrater reliability using intraclass correlation coefficients and applied generalizability theory.

Main Results:

• Interrater reliability for overall tasks ranged from good to excellent (ICC, 0.64-0.81).
• Generalizability studies indicated the marker system reliably distinguished teamwork competencies, supporting construct validity.
• Minor improvements in context-specific guidance may enhance rater reliability for specific competencies.

Conclusions:

• The behavioral marker system shows significant potential for measuring and differentiating teamwork competencies in ICUs.
• The system's reliability and validity support its use in critical care settings.
• Further refinement of context-specific guidance could optimize rater performance and system utility.
