Beyond the Logbook: Redefining What Surgical Competence Really Means
A logbook records that a procedure was performed. It says nothing about whether it was performed well, whether the decision to perform it was correct, or whether the patient had a good outcome. In an era where we have the tools to measure all of these things, continuing to treat case numbers as the primary marker of surgical readiness is a choice we should examine carefully.
The surgical logbook was introduced as a proxy for experience at a time when experience was the best available surrogate for competence. The logic was straightforward: sufficient exposure to a procedure would produce sufficient skill to perform it safely. This logic is not wrong, but it is incomplete. The relationship between case volume and clinical competence is not linear, not universal, and not well-captured by counting procedures without reference to how they were performed, what was learned from them, or what happened to the patients afterward.
What competence-based assessment offers
Competence-based medical education — the framework that underlies current UK and international postgraduate surgical training — shifts the question from "how many cases has this trainee done?" to "what can this trainee reliably do, with what level of supervision, based on demonstrated performance in assessed cases?" This is a more demanding and more honest framework. It requires systematic observation of performance, structured feedback, and progressive entrustment of procedural independence based on evidence rather than calendar time.
Entrustable Professional Activities — the framework of discrete, observable clinical tasks that form the building blocks of surgical competence — provide a vocabulary for this assessment. A trainee who has demonstrated entrustable competence in total shoulder arthroplasty in a well-supervised environment, with consistent procedural accuracy and sound peri-operative decision-making, is more reliably ready for independent practice than one who has the same procedure recorded in a logbook under variable supervision and without systematic outcome tracking.
Outcome integration: the missing piece
The most significant gap in current surgical training assessment is the absence of outcome data. Logbooks record that procedures were performed. They almost never record what happened to the patients on whom those procedures were performed. In an era where patient-reported outcomes, complication registries, and revision rates are available as clinical data, the absence of outcome feedback in training portfolios represents both a missed learning opportunity and an incomplete picture of competence.
A surgeon who has performed 200 procedures with consistently good outcomes and has reflected systematically on every one is more prepared for independent practice than one who has performed the same number without either. The logbook captures neither distinction.
Integrating outcome data into training portfolios — linking each trainee's cases to their documented outcomes, flagging outliers for supervisory discussion, and using outcome patterns as evidence for progression decisions — is the evolution in competency assessment that the existing infrastructure of registries and PROMs systems makes entirely feasible. It requires commitment and coordination, but the improvement in training quality and patient safety that it would produce makes that investment clearly worthwhile.
