Background: The aim of this study was to investigate whether junior surgical residents had successfully mastered bladder catheterization. Our hypothesis was that surgical residents would be overly confident in their abilities and underestimate the potential for case complexity., Materials and Methods: PGY 2-4 surgery residents (n = 44) were given 15 min. to complete three of four bladder catheterization simulations. Participants reported their mastery by rating confidence using a 5-point Likert scale. Multiple linear regression analysis was used to test predictors of procedure performance., Results: Participants made a total of 228 errors with an average of 5.1 errors (standard deviation = 2.6) per participant. The most common errors included not maintaining the sterile field (52.0%), failure to get urine return (20.3%), and inflating the catheter balloon before urine return (8.4%). Some residents committed the same error more than once. Presimulation confidence ratings ranged from "1" being not confident to "5" being extremely confident. Average presimulation confidence was 4.42 (range 1-5, standard deviation = 0.85). Sixteen (36%) residents ranked their presimulation confidence in problem-solving abilities as "moderately confident" or below, whereas 28 (64%) were "very confident" or above. The lower the resident's presimulation confidence in problem-solving, the more errors they committed during the simulation (beta = -0.33, t = -2.15, P = 0.04)., Conclusions: The residents did not perform as well as they anticipated when presented with more complicated bladder catheterization scenarios. Simulation can be used to identify and expose potential errors that may occur during complex presentations of basic procedures. This type of training and assessment may facilitate mastery., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Objective: The purpose of this study is to coevaluate resident technical errors and decision-making capabilities during placement of a subclavian central venous catheter (CVC). We hypothesize that there would be significant correlations between scenario-based decision-making skills and technical proficiency in central line insertion. We also predict residents would face problems in anticipating common difficulties and generating solutions associated with line placement., Design: Participants were asked to insert a subclavian central line on a simulator. After completion, residents were presented with a real-life patient photograph depicting CVC placement and asked to anticipate difficulties and generate solutions. Error rates were analyzed using chi-square tests and a 5% expected error rate. Correlations were sought by comparing technical errors and scenario-based decision-making skills., Setting: This study was performed at 7 tertiary care centers., Participants: Study participants (N = 46) largely consisted of first-year research residents who could be followed longitudinally. Second-year research and clinical residents were not excluded., Results: In total, 6 checklist errors were committed more often than anticipated. Residents committed an average of 1.9 errors, significantly more than the 1 error, at most, per person expected (t(44) = 3.82, p < 0.001). The most common error was performance of the procedure steps in the wrong order (28.5%, p < 0.001). Some of the residents (24%) had no errors, 30% committed 1 error, and 46 % committed more than 1 error. The number of technical errors committed negatively correlated with the total number of commonly identified difficulties and generated solutions (r (33) = -0.429, p = 0.021, r (33) = -0.383, p = 0.044, respectively)., Conclusions: Almost half of the surgical residents committed multiple errors while performing subclavian CVC placement. The correlation between technical errors and decision-making skills suggests a critical need to train residents in both technique and error management., (Copyright © 2016 Association of Program Directors in Surgery.

Background: The study investigates the relationship between motor coordination errors and total errors using a human factors framework. We hypothesize motor coordination errors will correlate with total errors and provide validity evidence for error tolerance as a performance metric., Methods: Residents' laparoscopic skills were evaluated during a simulated laparoscopic ventral hernia repair for motor coordination errors when grasping for intra-abdominal mesh or suture. Tolerance was defined as repeated, failed attempts to correct an error and the time required to recover., Results: Residents (N = 20) committed an average of 15.45 (standard deviation [SD] = 4.61) errors and 1.70 (SD = 2.25) motor coordination errors during mesh placement. Total errors correlated with motor coordination errors (r[18] = .572, P = .008). On average, residents required 5.09 recovery attempts for 1 motor coordination error (SD = 3.15). Recovery approaches correlated to total error load (r[13] = .592, P = .02)., Conclusions: Residents' motor coordination errors and recovery approaches predict total error load. Error tolerance proved to be a valid assessment metric relating to overall performance., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Urinary catheter insertion is a common procedure performed in hospitals. Improper catheterization can lead to unnecessary catheter-associated urinary tract infections and urethral trauma, increasing patient morbidity. To prevent such complications, guidelines were created on how to insert and troubleshoot urinary catheters. As nurses have an increasing responsibility for catheter placement, resident responsibility has shifted to more complex scenarios. This study examines the clinical decision-making skills of surgical residents during simulated urinary catheter scenarios. We hypothesize that during urinary catheterization, residents will make inconsistent decisions relating to catheter choices and clinical presentations., Methods: Forty-five general surgery residents (postgraduate year 2-4) in Midwest training programs were presented with three of four urinary catheter scenarios of varying difficulty. Residents were allowed 15 min to complete the scenarios with five different urinary catheter choices. A chi-square test was performed to examine the relation between initial and subsequent catheter choices and to evaluate for consistency of decision-making for each scenario., Results: Eighty-two percent of residents performed scenario A; 49% performed scenario B; 64% performed scenario C, and 82% performed scenario D. For initial attempt for scenario A-C, the 16 French Foley catheter was the most common choice (38%, 54%, 50%, P's < 0.001), whereas for scenario D, the 16 French Coude was the most common choice (37%, P < 0.01). Residents were most likely to be successful in achieving urine output in the initial catheterization attempt (P < 0.001). Chi-square analyses showed no relationship between residents' first and subsequent catheter choices for each scenario (P's > 0.05)., Conclusions: Evaluation of clinical decision-making shows that initial catheter choice may have been deliberate based on patient background, as evidenced by the most popular choice in scenario D. Analyses of subsequent choices in each of the catheterization models reveal inconsistency. These findings suggest a possible lack of competence or training in clinical decision-making with regard to urinary catheter choices in residents., (Copyright © 2016 Elsevier Inc.
