Episode 4 — Dr. Richard AngeloGuestDr. Richard (Rick) Angelo — Arthroscopic surgeon based in Seattle; former President of the Arthroscopic Association of North America (AANA). Holds a PhD in proficiency-based progression training.HostTony (relationship with Rick spans ~15 years, originating from a chance meeting at a conference in Sweden)Episode OverviewA deep-dive conversation on the fundamental failures of traditional surgical training and how proficiency-based progression (PBP) training offers a scientifically rigorous alternative. The discussion centres on the landmark Copernicus Study — the first study in medicine to use proficiency demonstration as an outcome measure.Key Topics Covered1. Limitations of the Traditional Apprenticeship ModelThe "see one, do one, teach one" model lacks objective assessmentDespite decades of training and significant investment, AANA could not verify whether skill acquisition was actually occurringComplication rates and suboptimal outcomes weren't improving with existing training efforts2. The Founding QuestionRick, during his time in the AANA presidential line, asked: "Is there a better way to train surgical skills?"This led to engagement with Tony's work on proficiency-based progression training3. Proficiency-Based Progression (PBP) Training — Core PrinciplesDefine a clear target: what does quality performance of a procedure look like?Deconstruct tasks into discrete, trainable componentsDevelop objective, binary metrics (did it occur or not?) rather than global rating scalesEstablish inter-rater reliability between assessorsTrainees must demonstrate a benchmark at each stage before progressing (including cognitive pre-course material — 83% threshold)Errors and deviations from optimal performance are trained explicitly — not just steps4. The Bankart Repair — Why It Was ChosenCommon procedure with a broad, transferable skill setSuited to task deconstruction and partial task simulationChosen by Rick and endorsed by the AANA core group5. Curriculum Before SimulationA critical insight: the curriculum and metrics must be developed first; simulation is chosen to match, not the other way aroundContrast with the wider medical field's focus on "eye candy" VR simulators that lack meaningful metricsThe FAST model (Fundamentals of Arthroscopic Surgery Training) was developed with Rob Pedowitz for knot tying — a low-cost, highly accurate partial task trainerEven a simple conical nail punch from a garage became an effective tool for measuring loop elongation6. The Copernicus Study — Design & ResultsThree study groups:Group A (Traditional): Lectures, open-access knot-tying lab, cadaver session — standard AANA approachGroup B (Simulator only): Access to the simulator without the PBP curriculum or metricsGroup C (PBP): Proficiency benchmarks at every stage — cognitive, knot-tying, and shoulder modelResults:Group B was 1.4× more likely than Group A to meet the benchmark (marginal)Group C participants (assigned to PBP, even without passing all benchmarks): 5.5× more likely than Group AGroup C participants who met all proficiency benchmarks: 7.5× more likely to meet the final benchmarkError reduction: ~56% decrease in Bankart errors; ~58% for rotator cuff repairIn one follow-up weekend cohort of 18 trainees: 89% demonstrated proficiency in Bankart repair; 83% in rotator cuff repair7. Key Finding: The Deficiency is in Training, Not TraineesPre-study concern about a "weed-out process" proved unfoundedWith quality training, almost all trainees can master the required skillsReferenced Frank Lewis (former Chair, American Board of Surgery) sharing the same observationStefano Pogliani's study demonstrated near-universal proficiency is achievable8. The Role of Errors in Surgical TrainingDistinguishing novice from expert performers is best predicted by error enactment, not step completionEach deviation from optimal performance creates a cascade risk — even if consequences aren't immediateUpcoming study expected to show errors are the best predictor of patient outcomes9. Broader Applicability to Procedure-Based MedicinePrinciples apply across disciplines — cardiology, robotics, and beyondContrast drawn with VR simulator manufacturers at the European Heart Rhythm Association Conference (Paris), where most simulations had no metricsChicken tissue models used successfully in robotic surgery training at €5 per chicken — effective without being high-tech10. Credentialing and Quality AssuranceDiscussion of whether PBP methodology could or should underpin credentialing for new procedures or devicesDevice failures in the field often attributable to inadequate clinician preparation, not device defectsPractical challenges for societal credentialing (procedure selection, remediation pathways, cost of metric development, legal defensibility)European Commission is moving toward micro-credentials for technical skills — awarded by universities, recognised across EU member ...
