Assessment of procedural skills training and performance in anesthesia using cumulative sum analysis (cusum) É valuation de la formation en habiletés techniques et de la performance en anesthésie au moyen de l'analyse des sommes cumulées (cusum) Abstract Purpose The current methods (work based assessments and logbooks) used to assess procedural competency and performance have well-documented deficiencies. Cumulative sum analysis (cusum), a statistical method that generates performance graphs over time, is an alternative tool that is not currently widely used. The purpose of this review is to investigate its current role in anesthetic procedural skills training and performance.Tim
