OBJECTIVE Based on the Competency Assessment Tool, herein we developed an assessment instrument suitable to evaluate the implantation of central intravenous devices. BACKGROUND Surgical assessment is based mainly on the subjective impressions of the teacher. Based on the "Competency Assessment Tool" (CAT) developed for the evaluation of technical surgical skills in minimally invasive colorectal resection, we designed an assessment tool suitable to evaluate the implantation of central venous access devices performed by junior surgical trainees. METHODS Four major assessments during the different steps of the intervention were used in this evaluation. Each of these tasks was divided into four sub-domains according to surgical skill. In addition to the CAT score, the apprentices' skills were evaluated using a visual assessment that was quantified using an analogue scale (value from 1 to 10). The candidates were classified into junior and senior trainees depending on the number of procedures they had already performed and on their surgical experience. RESULTS 71 procedures were evaluated during the study period. Seven senior trainees conducted 43 procedures and five junior trainees performed 28 interventions. The senior trainees had significantly higher CAT scores than junior candidates, and the scores fluctuated according to surgical experience, usually reaching their peak after 10 procedures. CONCLUSIONS The CAT model is well suited for the assessment of surgical trainees during central venous access device implantation. It enables a close assessment of the learning process and the technical skills of trainees, which helps them improving in a safe, standardized manner.
