Abstract
Competency-based education has mandated accurate intra-operative assessment tools. We aimed to define consensus-based open surgical skills perceived by experts as critical for assessment.
A mixed-method design was employed: systematic review and e-Delphi methodology.
The study was performed at McGill University-affiliated large tertiary academic centers in Montreal, Quebec, Canada.
Per PRISMA guidelines, a peer-reviewed search strategy was employed. Studies published in English and those describing technical skill assessment of open abdominal surgery were included; subspecialty-specific skills, conference abstracts, academic memoirs were excluded. Most-cited skills were subjected to e-Delphi methodology to identify those deemed essential by experts, based a 3-point Likert scale. Eighteen McGill University-affiliated general surgeons, representing a variety of subspecialties of General Surgery, were invited to answer the questionnaire.
Around 120 of 4285 references were retained for analysis. The 12 most cited skills included suturing, tissue and instrument handling, movement economy, instrument knowledge, knot tying, flow, knowledge of procedure, completion time, dissection technique, knowledge of anatomy and sterile technique; 6 of these achieved high or perfect scores and agreement after 2 rounds of survey: suturing, sterile technique, knot tying, knowledge of anatomy, knowledge of procedure, and tissue handling. Median standard deviation decreased (0.495 to 0.450) from first to second round, indicating improvement in consensus.
These results will help develop and validate the OSCAR (objective structured clinical assessment rubric) assessment tool for immediate intra-operative feedback of open technical skills for surgical trainees.
