    Summary

    Anesthesiologists were distracted from patient care 46% of the time during surgery. Future research should focus on reducing non-patient-centered activities to improve surgical safety.

    Area of Science:

    • Anesthesiology
    • Human Factors Engineering
    • Patient Safety

    Background:

    • Anesthesiologist's attention is critical for patient safety during surgery.
    • Previous studies indicate significant time spent away from direct patient observation.

    Purpose of the Study:

    • To categorize intraoperative anesthesiologist activities.
    • To quantify the proportion of time spent on patient-centered versus non-patient-centered tasks.
    • To compare current findings with historical data on anesthesiologist distraction.

    Main Methods:

    • A time/motion study was conducted in an anesthesiology department.
    • Intraoperative events were classified into three categories: direct patient-centered, indirect patient-centered, and non-patient-centered activities.
    • Data were analyzed to determine the percentage of time spent in each category.

    Main Results:

    • A significant portion of anesthesiologist's time was dedicated to non-patient-centered activities.
    • The proportion of time anesthesiologists were distracted from the patient was comparable to earlier findings (46%).

    Conclusions:

    • Anesthesiologists spend a substantial amount of time on tasks not directly related to patient care.
    • Minimizing non-patient-centered activities and distractions is crucial for enhancing patient safety during surgical procedures.
    • Further development of monitoring equipment and workflow should aim to reduce these distractions.
