Methodological approaches to anaesthetists' workload in the operating theatre

Area of Science:

• Anesthesiology
• Human Factors Engineering
• Occupational Health

Background:

• Workload is a critical factor in healthcare, particularly in high-stakes environments like anesthesia.
• Understanding and measuring workload are essential for ensuring patient safety and optimizing performance.
• Current research on workload in anesthesia is limited, necessitating further investigation.

Purpose of the Study:

• To review the fundamental concepts and measurement methods of workload in anesthesiology.
• To analyze the components and contributing factors of operating room workload using an ergonomic model.
• To examine the relationship between workload, training, supervision, and the quality/safety of anesthetic care.

Main Methods:

• Ergonomic-based model analysis of anesthesiologists' operating room activities.
• Review of existing evidence on workload measurement and its impact.
• Analysis of workload patterns across different perioperative stages.

Main Results:

• Induction and emergence phases are identified as the most demanding periods, involving both practical and non-technical tasks.
• Simultaneous task management is a key feature of anesthetic practice.
• Experienced anesthesiologists may possess 'spare capacity' during routine cases, potentially serving as a safety margin.

Conclusions:

• Measurement of workload, especially for overlapping tasks, is still evolving.
• The effects of production pressure and mental overload on anesthetic care require further study.
• Evidence-based recommendations for staffing and task delegation in anesthesia cannot yet be made, though workload management strategies may be beneficial.
