Background: Medical procedures are traditionally taught informally at patients' bedside through observation and practice using the adage "see one, do one, teach one." This lack of formalized training can cause trainees to be unprepared to perform procedures independently. Simulation based education (SBE) increases competence, reduces complications, and decreases costs. We developed, implemented, and evaluated the efficacy of a right heart catheterization (RHC) SBE curriculum., Methods: The RHC curriculum consisted of a pretest, video didactics, deliberate practice, and a posttest. Pre-and posttest skills examinations consisted of a dichotomous 43-item checklist on RHC skills and a 14-item hemodynamic waveform quiz. We enrolled two groups of fellows: 6 first-year, novice cardiology fellows at Northwestern University in their first month of training, and 11 second- and third-year fellows who had completed traditional required, level I training in RHC. We trained the first-year fellows at the beginning of the 2018-2019 year using the SBE curriculum and compared them to the traditionally-trained cardiology fellows who did not complete SBE., Results: The SBE-trained fellows significantly improved RHC skills, hemodynamic knowledge, and confidence from pre- to posttesting. SBE-trained fellows performed similarly to traditionally-trained fellows on simulated RHC skills checklists (88.4% correct vs. 89.2%, p = .84), hemodynamic quizzes (94.0% correct vs. 86.4%, p = .12), and confidence (79.4 vs. 85.9 out of 100, p = .15) despite less clinical experience., Conclusions: A SBE curriculum for RHC allowed novice cardiology fellows to achieve level I skills and knowledge at the beginning of fellowship and can train cardiology fellows before patient contact., (© 2020 Wiley Periodicals LLC.)

Objectives: The aim of this study is to determine whether simulation-based education (SBE) translates into reduced procedure time, radiation, and contrast use in actual clinical care., Background: As a high volume procedure often performed by novice cardiology fellows, diagnostic coronary angiography represents an excellent target for SBE. Reports of SBE in interventional cardiology are limited and there is little understanding of the potential downstream clinical impact of these interventions., Methods: All diagnostic coronary angiograms performed at a single center between January 1, 2011 and June 30, 2015 were analyzed. Random effects linear regression models were used to compare outcomes between procedures performed by 12 cardiology fellows who underwent simulation-based training and those performed by 20 traditionally trained fellows., Results: Thirty-two cardiology fellows performed 2,783 diagnostic coronary angiograms. Procedures performed by fellows trained with SBE were shorter (mean of 23.98 min vs. 24.94 min, P = 0.034) and were performed with decreased radiation (mean of 56,348 mGycm 2 vs. 66,120 mGycm 2 , P < 0.001). After controlling for year in training, procedure year, access site, and supervising attending physician, training on the simulator was independently associated with 117 fewer seconds of fluoroscopy time per procedure (P = 0.04)., Conclusions: Diagnostic coronary angiography SBE is associated with decreased use of fluoroscopy in downstream clinical care. SBE may be a useful tool to reduce radiation exposure in the cardiac catheterization laboratory., (© 2017 Wiley Periodicals, Inc.)

Objectives: We assessed whether post-operative delirium is associated with healthcare utilization and overall survival after trans-catheter aortic valve replacement., Background: Delirium, a common syndrome among hospitalized older adults, is associated with increased morbidity and mortality., Methods: We reviewed 294 transcatheter aortic valve replacement cases between June 2008 and February 2015 at a tertiary care academic medical center. Post-operative delirium was identified by confusion assessment method screening and clinician diagnosis., Results: Delirium was identified in 61 patients (21%). Non-femoral access for trans-catheter aortic valve replacement was more common in delirious patients than in non-delirious patients (41% vs. 27%, P = 0.04). Delirious patients had diminished overall survival after trans-catheter aortic valve replacement compared to non-delirious patients (1-year survival 59% vs. 84%, log-rank P = 0.002). After adjusting for age, Society of Thoracic Surgeons predicted 30-day mortality, and access type; delirium remained independently associated with diminished overall survival (hazard ratio 2.01, 95% confidence interval 1.21-3.33, P = 0.007). The delirium group had longer mean hospital stay (13.3 ± 9.5 days vs. 6.7 ± 3.8 days, P < 0.001) and a higher rate of discharge to a rehabilitation facility (61% vs. 27%, P < 0.001), but there was no difference in 30-day hospital re-admission rates or 30-day mortality based on delirium status., Conclusions: Delirium occurs in one out of five patients after trans-catheter aortic valve replacement and is associated with diminished survival and increased healthcare utilization. Further studies are needed to clarify whether strategies aimed at reducing delirium after trans-catheter aortic valve replacement may improve outcomes in this high-risk subset. © 2016 Wiley Periodicals, Inc., (© 2016 Wiley Periodicals, Inc.)

Objectives: We studied the impact of operator experience on trans-radial (TR) cardiac catheterization performance in contemporary practice., Background: TR cardiac catheterization offers advantages over trans-femoral (TF) cardiac catheterization, but the TR approach has been slowly adopted in the United States., Methods: We reviewed all cases of attempted TR cardiac catheterization at a single tertiary care medical center from May 2008 until April 2015. We classified the attending operator TR case experience at the time of each case, and the control group constituted cases performed by operators with >300 TR cases. Study endpoints were TR cannulation failure, TF cross-over, contrast medium dose, and fluoroscopy time., Results: Over the study period, 4177 attempted TR cardiac catheterization cases were performed. The percentage of TR cases performed with percutaneous coronary intervention (PCI) increased from 14.0% in 2009 to 30.2% in 2015 (P-trend <0.001). The rate of TR cannulation failure decreased from 4.3% in 2009 to 2.0% in 2015 (P-trend = 0.071), and the rate of TF cross-over decreased from 4.3% in 2009 to 3.2% in 2015 (P-trend = 0.034). Operators with over 100 cases had the lowest odds of TR cannulation failure, while operators with over 200 cases had the lowest odds of TF cross-over. Operators with over 200 cases used the lowest mean contrast medium dose and mean fluoroscopy time., Conclusions: Increasing operator TR experience is associated with lower odds of TR cannulation failure and TF cross-over, as well as lower contrast medium dose and fluoroscopy time. © 2016 Wiley Periodicals, Inc., (© 2016 Wiley Periodicals, Inc.)
