Manual record keeping is not necessary for anesthesia vigilance

Area of Science:

• Anesthesiology
• Human Factors Engineering
• Patient Safety

Background:

• Intraoperative vigilance is crucial for patient safety during anesthesia.
• Concerns exist that manual record-keeping may divert anesthesia residents' attention from patient monitoring.

Purpose of the Study:

• To compare the intraoperative vigilance of anesthesia residents when performing manual charting versus when an assistant handles record-keeping.

Main Methods:

• Nine anesthesia residents participated in 36 general anesthesia cases.
• Vigilance was assessed by measuring residents' detection rate and response time to simulated monitor abnormalities.
• Record-keeping was alternated between the resident and a human assistant across cases.

Main Results:

• No significant differences in response times or detection rates were observed when an assistant performed charting compared to when residents charted manually.
• Shorter surgical cases correlated with decreased vigilance during the maintenance phase, specifically when residents performed manual charting.

Conclusions:

• Anesthesia residents maintain consistent vigilance regardless of whether they manually chart or have an assistant record data.
• The study challenges the assumption that eliminating manual record-keeping tasks will inherently decrease intraoperative vigilance.
