Assessment of surgical site infection (SSI) depth for 40 vignettes (20 cardiac surgery cases and 20 gastrointestinal surgery cases) developed based on real patients in three French university hospitals.

SSI Depth was scores on a 4-point scale: scale 1, no SSI in vignettes with scores lower than 4 on the 7-point Likert for the absence/presence of SSI; scale 2, superficial SSI; scale 3, uncertainty about SSI diagnosis, scale 4, deep/organ space SSI in vignettes scored 4 or more on the 7-point Likert scale.*For intraspecialty 20 vignettes were scored twice and for interspecialty 34 vignettes were scored 7 times).**missing values due a computer assignment glitch.***Depth was not scored because scores of the absence/presence of SSI were lower than 4 on the 7-point Likert scale.
