Cumulative Sum learning curves (CUSUM) in basic anaesthesia procedures
Abstract
Objectives:To create Cumulative Sum learning curves - CUSUM - for 6 anaesthesia procedures.
Methodology: We assessed 764 orotracheal intubations, 251 spinal anaesthesia procedures, 189 epidural anaesthesia procedures, 143 subclavian vein catheterizations, 135 radial artery catheterizations, and 100 internal jugular catheterizations in 4 anaesthesia residents, and developed CUSUM learning curves.
Results: In endotracheal intubation we found the following: 75% of the learners achieved 95% success with 65 ± 24 cases; in spinal anaesthesia, 50% of the learners attained the 85% success rate with 35 cases; in epidural anaesthesia, 100% of the learners attained 80% success with 13 ± 5 cases; in subclavian vein catheterization, 100% of the learners reached 80% success with 21 ± 6 cases; in radial artery catheterization, 25% of the learners achieved an 80% success rate with 39 cases. For internal jugular catheterization it was not possible to collect sufficient information to report statistically significant data.
Conclusions: CUSUM charts are tools that allow monitoring and early detection of changes in psychomotor learning in anaesthesia, providing meaningful information in relation to quality standards.
