 ====Commentary==== ====Commentary====
 +===Key===
 +  * Good: low-fi, can differentiate expert/novice
 +  * Bad: manual ? inter-rater?; how does it correlate with real micro skills?
 +    * need an expert to do it
 +
 +===Assessment Model===
 +  * Outcome only
 +  * Assessor score. Bias, rating, score - [[ac:stats:scores|statistical considerations]]
 +  * Weighting - each error given equal weight -- is that really the case? see [[bk:altman1991|Altman]] page 14 on Scores.
 +    * Experts: also made errors (between 2-2.5 errors); do they make different errors?
 +  * Size of rat aorta?
 +  * Can differentiate expert, but how does it correlate with patency?
 +
 +===Methodology===
 +  * 29 participants with 2 anastomosis each on day 3 and day 5; 2 experts with 3 anastomosis on D1 and 3 on D3
 +    * "expert" group very concentrated
 +  * SD for expert group higher (2.5) vs (1.0-1.3) for other groups --> there is some variability anastomosis to anastomosis
 +
 +===Discussion===
 +
 +The authors quote [[jnl:kaufman1987:Kaufman]] (whom I assume takes from [[pp:Fitts-Posner]]), the cognitive, associative and autonomous stages in the development of technical skill (or expertise). I am not so convinced this model is entirely useful for surgical training. It is useful for some surgical task training, but not for surgery in general. See page on [[co:expertise]].
 +
 +===So What?===
 +  * Authors suggest: ALI > 6 == novice, ALI 3-6 == intermediate, ALI < 3 == expert; BUT can you really improve so quickly as from novice to intermediate?
