Assessment of procedural skills training and performance in anesthesia using cumulative sum analysis (cusum)

Abstract

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

Defining and developing expertise in tracheal intubation using a GlideScope® for anaesthetists with expertise in Macintosh direct laryngoscopy: an in‐vivo longitudinal study

“…However, there is no widely accepted definition of either expertise or even minimal competence [3], and as a complex skill, assessment based solely on time and/or success would be unlikely to define the learning process adequately [4,5]. Even the nomenclature used to describe expertise is variable.…”

Determining the amount of training needed for competency of anesthesia trainees in ultrasonographic identification of the cricothyroid membrane

“…Learning curves using CUSUM have been used to assess several procedural skills in anaesthesia [20, 21]. The CUSUM analysis is an effective mathematical model to define learning curves for technical skills [18, 22].…”

“…Competence was defined as 90% success rate in a series of ultrasound scans [20, 21]. The secondary outcomes included (a) the overall success rate, (b) the time (sec.)…”

Comparison of Analgesic Outcomes Following Sciatic Nerve Blockade Performed by Resident Trainees and Nurse Anesthetists

“…Global procedural scores and performance times for axillary and interscalene brachial plexus nerve blockade for both trainees and practitioners demonstrated improvement in these parameters that was related to the number of procedures completed and weeks in training [5,6]. Clinical outcomes monitored by cumulative summation (CUSUM) statistical methods demonstrate resident variability in the number of repetitions necessary to acquire the minimal standard of technical proficiency for any given procedure [7]. Sciatic popliteal nerve blockade (SNB) placed by podiatry residents had an overall success rate of 72.4% with no difference in this proportion with respect to months of training [8].…”
