Study summary

High-fidelity simulation (HFS) is a learning method extensively used for training of surgical specialty (including anesthesia) and nurses. It has a beneficial effect on knowledge of algorithms, team working, early warning scores, and communication. Various skills can be learned using a standardized simulation programs.

The complexity of instructional design may produce cognitive overload, high stress level and anxiety. This may increase fatigue, facilitate errors, and is associated with inferior task performance which may impede memorization of learned skills resulting in inefficient learning/simulation failure. Subjectively reported scales can accurately identify the level of perceived workload and mental demand in individuals during simulation tasks. One example is the National Aeronautics and Space Administration (NASA)-TLX - the most accepted subjective measure of human workload in various industries including medicine.

Surgical specialty (including anesthesia) and nurses training curriculum in Lyon, France, includes several HFS scenarios with a large panel of critical events. The investigators aim to evaluate the effect of burden of workload and stress perceived by surgical specialty (including anesthesia) residents and nurses during HFS on the learning performance, and to grade different learning scenarios by their difficulty.

Read the detailed description

In this observational study investigators aim to measure anesthesiology, surgeon residents and nurses' workload, stress level, and performance on high-fidelity simulation scenarios used routinely in the current anesthesiology, nurse and surgical training curriculum. A NASA TLX scale, 100 points numeric scale for anxiety (0 - no anxiety; 100 - maximal anxiety), automated quantitative pupillometry, Team Emergency Assessment Measure scale will be used to evaluate a workload, anxiety, stress, and performance. Age, sex, previous experience of HFS will be noted. All data will be anonymized. The participation in this study is voluntary and one can withdraw from this study at any time prior to or after the completion of any interview without any penalty.

Two investigators will independently evaluate the performance of HFS by direct observation and video record if necessary. NASA TLX questionnaire will be administrated immediately after HFS scenario and before the debriefing. Anxiety scale and pupillometry will be administrated before the beginning of HFS scenario and upon its completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
