Clinical Performance and Multitasking in Anesthesia : a Simulation-based Study (FOCUS)

2026年6月30日 更新者：University Hospital, Grenoble

Cognitive failure under multitasking conditions has been demonstrated in various settings, including healthcare. However, in anesthesiology, the impact of multitasking on clinical performance has not yet been fully characterized.

The objective of our study is to evaluate the impact of multitasking on anesthesiologists' clinical performance in a simulated setting.

详细说明

This study is a prospective, single-center, non-interventional study. The study was classified as non-interventional by the institutional research committee, as the intervention consists of simulation training and the study population comprises healthcare practitioners.

The study participants are anesthesiologists, including attending physicians and residents. Each participant will serve as their own control. The study will comprise two visits: one intervention visit consisting of a multitasking simulation session, and one control visit involving clinical questions administered under quiet conditions. The order of the visits will be randomized between participants using a crossover design in order to minimize potential learning bias.

The multitasking condition will consist of performing manual mask ventilation on a manikin while answering oral clinical questions administered in the form of Script Concordance Tests (SCTs). Participants will be instructed to ventilate the manikin with a tidal volume of 500 mL and a respiratory rate of 15 breaths/minute.

Clinical reasoning under quiet conditions will consist of answering oral clinical questions in the SCT format.

The study will use a 44-item Script Concordance Test (SCT) distributed across 20 anesthesiology clinical vignettes. The vignettes are distributed as follows: 8 vignettes with 3 items, 8 vignettes with 2 items, and 4 vignettes with 1 item. The vignettes were adapted, without modification of their content, to be compatible with oral administration and the simulation scenario.

In addition, for each participant, the SCT clinical vignettes will be randomized between the "simulation vignettes" and the "control vignettes," with stratification according to the number of items per vignette. Five vignettes will be allocated to the intervention condition and fifteen to the control condition. This approach will help limit the effect of differences in vignette difficulty that could otherwise bias the results. At the group level, all clinical vignettes will ultimately be assessed in both the simulation and control conditions.

Detailed information is available in the study protocol.

主要结果指标

结果测量
措施说明
大体时间
Concordance score with the expert panel on a Script Concordance Test (SCT)
大体时间：At two time points: - During simulation session under multitasking conditions - During control visit under quiet conditions
Each item of the SCT is scored out of 1 point, and the sum of the points, converted to a 100-point scale, defines the percentage of concordance with the expert panel.
At two time points: - During simulation session under multitasking conditions - During control visit under quiet conditions

次要结果测量

结果测量
措施说明
大体时间
Time to answer items of the script concordance test (seconds)
大体时间：Two time points: intervention and control.

Time between end of question and beggining of answer for each item of the script concordance test.

Evaluates the interruption lag.
Two time points: intervention and control.
Manual ventilation performance assessed by variance of expiratory tidal volume (ml)
大体时间：- Training before simulation: baseline - During simulation: ventilation only, ventilation plus clinical questions
Participants will be instructed to ventilate with an expiratory tidal volume (Vte) between 450 and 500 mL at a respiratory rate of 15 breaths per minute. Variability in Vte will be used as an indicator of the difficulty in complying with these instructions.
- Training before simulation: baseline - During simulation: ventilation only, ventilation plus clinical questions
Manual ventilation performance assessed by variance of respiratory rate (cycles/minute)
大体时间：- Training before simulation: baseline - During simulation: ventilation only, ventilation plus clinical questions
Participants will be instructed to ventilate with an expiratory tidal volume (Vte) between 450 and 500 mL at a respiratory rate of 15 breaths per minute. Variability in respiratory rate will be used as an indicator of the difficulty in complying with these instructions.
- Training before simulation: baseline - During simulation: ventilation only, ventilation plus clinical questions
Cognitive load assessed by the NASA-TLX index (score out of 100)
大体时间：A two time points: - Evaluating cognitive load of manual ventilation alone, before simulation after training. - Evaluation cognitive load of multitasking, at the end of the simulation session
The Official NASA Task Load Index (TLX) is a subjective workload assessment tool. By incorporating a multi-dimensional rating procedure, NASA TLX derives an overall workload score based on a weighted average of ratings on six subscales: mental demand, physical demand, temporal demand, performance, effort, frustration.
A two time points: - Evaluating cognitive load of manual ventilation alone, before simulation after training. - Evaluation cognitive load of multitasking, at the end of the simulation session
