Preparing interns for clinical practice through an institution-wide simulation-based mastery learning program for...

Central venous catheter (CVC) placement is a challenging procedure with known iatrogenic risks. However, there are no residency program requirements to demonstrate baseline CVC procedural competency. Competency-based procedural education has been shown to decrease CVC-associated morbidity, but there has been limited literature about institution-wide efforts to ensure initial trainee competency for CVC placement. This study describes the implementation of a competency-based CVC curriculum for first-year interns across an institution before supervised clinical care. An institution-wide, simulation-based mastery training curriculum was designed to assess initial competency in CVC placement in first-year residents during 2021 and 2022. A checklist was internally developed with a multidisciplinary team. Using the Mastery-Angoff technique, minimum passing standards were derived to define competency levels considered appropriate for intern participation in supervised clinical care. Interns were trained through the competency-based program with faculty assessing intern performance using the CVC checklist to verify procedural competency. Over 2 academic cycles, 229 interns from 20 specialties/subspecialties participated. Overall, 83% of interns met performance standards on their first posttest attempt, 14% on the second attempt, and 3% on the third attempt. Interns from both cycles demonstrated significant improvement from baseline to posttest scores (P < .001). Overall, 10.5% of interns performed dangerous actions during assessment (malpositioning, retained guidewire, or carotid dilation). All interns ultimately achieved the passing standard to demonstrate initial competency in the simulation assessment. All participating interns demonstrated simulation-based competency allowing them to place CVCs under supervised clinical care. Dangerous actions, however, were not uncommon. Simulation-based teaching and learning frameworks were a feasible method to promote patient safety through an institutional-wide verification of preliminary procedural competency.
