Article description

Summary:

• The study aim was to measure the timing of discrete events during perioperative central venous catheter (CVC) placements with wearable video-recording technology;
• Single-center observational study;
• The study included 82 CVC placements procedures with eye-tracking glasses performed by clinical anesthesia residents, cardiothoracic anesthesia fellows, and attending anesthesiologists in the cardiac operating rooms between September 2022 and May 2023;
• The authors measured the total time to complete the CVC placement, phase-specific time, and specific times of interest, and compared these times across three training levels;
• CVC placement time was significantly longer when the procedure included a pulmonary artery catheter insertion ( 1,170 ± 364, 923 ± 272, and 596 ± 226 seconds; F2,63 = 12.71, p < 0.0001);

Conclusions:

• The authors used wearable video to measure task times during CVC placement and proposed a new timing schema;
• Future work will utilize the eye-tracking capabilities of the existing hardware to identify inefficiencies and formulate targeted interventions to enhance trainee performance and patient safety.
