Can Nonclinician Raters Be Trained to Assess Clinical Reasoning in Postencounter Patient Notes?

PURPOSE: Clinical reasoning is often assessed through patient notes (PNs) following standardized patient (SP) encounters. While nonclinicians can score PNs using analytic tools such as checklists, these do not sufficiently encompass the holistic judgments of clinician faculty. To better model faculty judgments, the authors developed checklists with faculty-specified scoring formulas embedded in spreadsheets and studied the resulting interrater reliability (IRR) of nonclinician raters (SPs and medics) and student pass/fail status. METHOD: In Study 1, nonclinician and faculty raters rescored PNs of 55 third-year medical students across 5 cases of the 2017 Graduation Competency Examination (GCE) to determine IRR. In Study 2, nonclinician raters scored all notes of the 5-case 2018 GCE (178 students). Faculty rescored all notes of failing students and could modify formula-derived scores if faculty felt appropriate. Faculty also rescored and corrected scores of additional notes for a total of 90 notes (3 cases, including failing notes). RESULTS: Mean overall percent exact agreement between nonclinician and faculty ratings was 87% (weighted kappa, 0.86) and 83% (weighted kappa, 0.88) for Study 1 and Study 2, respectively. SP and medic IRRs did not differ significantly. Four students failed the note section in 2018; 3 passed after faculty corrections. Few corrections were made to nonfailing students' notes. CONCLUSIONS: Nonclinician PN raters using checklists and scoring rules may provide a feasible alternative to faculty raters for low-stakes assessments and for the bulk of well-performing students. Faculty effort can be targeted strategically at rescoring notes of low-performing students and providing more detailed feedback.

Atrioventricular nodal reentry with retrograde lower common pathway block: a case report.

Retrograde lower common pathway block during AV nodal reentrant tachycardia has rarely been reported. In this report, we demonstrate retrograde ventriculoatrial block during sinus rhythm and during AV nodal reentrant tachycardia in a woman with recurrent supraventricular tachycardia. In addition, evidence of antegrade decremental lower common pathway conduction is presented that produced variable HA intervals despite a constant atrial cycle length. These features may lead to the misdiagnosis of atrial tachycardia if not recognized.

Results of a minimally invasive surgical pulmonary vein isolation and ganglionic plexi ablation for atrial fibrillation: single-center experience with 12-month follow-up.

BACKGROUND: The Cox Maze procedure for treatment of medically refractory atrial fibrillation (AF) is limited by its complexity and requirement for cardiopulmonary bypass. Long-term follow-up and success using criteria established by the Heart Rhythm Society/European Heart Rhythm Association/European Cardiac Arrhythmia Society consensus statement have not been reported for surgical AF ablation. We describe the results of using a thorascopic approach and radiofrequency energy to perform bilateral pulmonary vein isolation and left atrial ganglionic plexi ablation for treatment of AF. METHODS AND RESULTS: Forty-five (33 paroxysmal; 12 persistent) consecutive patients underwent thorascopic bilateral radiofrequency pulmonary vein isolation, ganglionic plexi ablation, ligament of Marshall ablation, and left atrial appendage exclusion by a single surgeon. Forty-three patients were prospectively followed without antiarrhythmic drugs for a minimum of 1 year with a 30-day continuous event monitor or pacemaker interrogation at 6 and 12 months. Failure was defined as any atrial tachyarrhythmia of >30 seconds' duration occurring >90 days after surgery. Mean follow-up was 516+/-181 days (202 to 858 days). Twenty-eight (65%) patients had no atrial tachyarrhythmia >30 seconds by 1 year, and 15 (35%) patients had atrial tachyarrhythmia recurrences by 1 year. Eight of 15 patients with recurrent AF had catheter ablation resulting in elimination and/or reduction of AF episodes in 7 of 8 patients. Four of 15 patients had AF elimination or reduction with antiarrhythmic drugs alone. Three patients did not benefit from surgery and received rate control only. There were no deaths; 1 phrenic nerve injury and 2 pleural effusions were the only major complications. CONCLUSIONS: The single procedure success at 1-year follow-up for surgical pulmonary vein isolation and ganglionic plexi ablation is 65%. Atrial tachyarrhythmia recurrences after surgery are usually responsive to catheter ablation and/or antiarrhythmic drugs.
