Errors During Resuscitation: The Impact of Perceived Authority on Delivery of Care.

OBJECTIVE: The aim of this study was to determine the influence of perceived authority on pediatric resuscitation teams' response to an incorrect order given by a medical superior. METHODS: As part of a larger multicenter prospective interventional study, interprofessional pediatric resuscitation teams (n = 48) participated in a video-recorded simulated resuscitation scenario with an infant in unstable, refractory supraventricular tachycardia. A confederate actor playing a senior physician entered the scenario partway through and ordered the incorrect dose and delivery method of the antiarrhythmic, procainamide. Video recordings were analyzed with a modified Advocacy Inquiry Scale, assessing the teams' ability to challenge the incorrect order, and a novel confederate hierarchical demeanor rating. The association between Advocacy Inquiry score and hierarchical demeanor rating, and whether or not the confederate's incorrect order was followed were determined. RESULTS: Fifty percent (n = 24) of resuscitation teams followed the confederate's incorrect order. The teams' ability to challenge the incorrect order (P < 0.0001) and confederate hierarchical demeanor rating (P < 0.05) were significantly associated with whether or not the incorrect order was followed. Significant differences between rates of following the incorrect order at different study sites were observed (P < 0.05). CONCLUSIONS: The reluctance of resuscitation teams to appropriately challenge the incorrect order resulted in a high rate of inappropriate medication administration. The rate of teams following the incorrect order was significantly associated with poor challenging of the incorrect order and the hierarchical demeanor of the perceived authority figure. Institution-based factors may impact this rate of incorrect medication administration.

Improved Clinical Performance and Teamwork of Pediatric Interprofessional Resuscitation Teams With a Simulation-Based Educational Intervention.

OBJECTIVES: To measure the effect of a 1-day team training course for pediatric interprofessional resuscitation team members on adherence to Pediatric Advanced Life Support guidelines, team efficiency, and teamwork in a simulated clinical environment. DESIGN: Multicenter prospective interventional study. SETTING: Four tertiary-care children's hospitals in Canada from June 2011 to January 2015. SUBJECTS: Interprofessional pediatric resuscitation teams including resident physicians, ICU nurse practitioners, registered nurses, and registered respiratory therapists (n = 300; 51 teams). INTERVENTIONS: A 1-day simulation-based team training course was delivered, involving an interactive lecture, group discussions, and four simulated resuscitation scenarios, each followed by a debriefing. The first scenario of the day (PRE) was conducted prior to any team training. The final scenario of the day (POST) was the same scenario, with a slightly modified patient history. All scenarios included standardized distractors designed to elicit and challenge specific teamwork behaviors. MEASUREMENTS AND MAIN RESULTS: Primary outcome measure was change (before and after training) in adherence to Pediatric Advanced Life Support guidelines, as measured by the Clinical Performance Tool. Secondary outcome measures were as follows: 1) change in times to initiation of chest compressions and defibrillation and 2) teamwork performance, as measured by the Clinical Teamwork Scale. Correlation between Clinical Performance Tool and Clinical Teamwork Scale scores was also analyzed. Teams significantly improved Clinical Performance Tool scores (67.3-79.6%; p < 0.0001), time to initiation of chest compressions (60.8-27.1 s; p < 0.0001), time to defibrillation (164.8-122.0 s; p < 0.0001), and Clinical Teamwork Scale scores (56.0-71.8%; p < 0.0001). A positive correlation was found between Clinical Performance Tool and Clinical Teamwork Scale (R = 0.281; p < 0.0001). CONCLUSIONS: Participation in a simulation-based team training educational intervention significantly improved surrogate measures of clinical performance, time to initiation of key clinical tasks, and teamwork during simulated pediatric resuscitation. A positive correlation between clinical and teamwork performance suggests that effective teamwork improves clinical performance of resuscitation teams.

Description of PICU Unplanned Readmission.

OBJECTIVES: ICU readmission within 48 hours of discharge is associated with increased mortality. The objectives of this study were to describe the frequency of, factors associated with, and outcomes associated with unplanned PICU readmission. DESIGN: A retrospective case-control study was performed. We evaluated 13 candidate risk factors and report patient outcomes following readmission. Subgroup analyses were performed for patients discharged from the cardiac PICU and medical-surgical PICU. SETTING: The study was undertaken at the Hospital for Sick Children, Department of Critical Care Medicine. PATIENTS: Eligible patients were discharged from the PICU to an inpatient ward between December 2006 and January 2013. Case patients were readmitted to the PICU within 48 hours of discharge. MEASUREMENTS AND MAIN RESULTS: There were 10,422 eligible patient discharges; 264 (2.5%) were readmitted within 48 hours. In the univariable analysis, unplanned readmission was associated with PICU patient admissions of younger age, lower weight, greater duration of PICU stay, greater cumulative stay in PICU in the past 2 years, higher Pediatric Logistic Organ Dysfunction score on PICU discharge, discharge outside goal discharge time (06:00-11:59 hr), use of extracorporeal organ support during ICU stay, greater Bedside Pediatric Early Warning Score, at discharge and discharge from the cardiac PICU. In the multivariable analysis, the factors most significantly associated with unplanned PICU readmission were length of stay more than 48 hours, greater cumulative length of PICU stay in the past 2 years, discharge from cardiac PICU, and higher Pediatric Logistic Organ Dysfunction and Bedside Pediatric Early Warning Scores on index discharge. Mortality was 1.8 times (p = 0.03) higher in patients with an unplanned PICU readmission compared with patients during their index PICU admission. CONCLUSIONS: The only potentially modifiable factors we found associated with PICU readmission within 48 hours of discharge were discharge time of day and the Pediatric Logistic Organ Dysfunction and Bedside Pediatric Early Warning Scores at the time of PICU discharge.

Validity and Feasibility Evidence of Objective Structured Clinical Examination to Assess Competencies of Pediatric Critical Care Trainees.

OBJECTIVE: The purpose of this study was to provide validity and feasibility evidence for the use of an objective structured clinical examination in the assessment of pediatric critical care medicine trainees. DESIGN: This was a validation study. Validity evidence was based on Messick's framework. SETTING: A tertiary, university-affiliated academic center. SUBJECTS: Seventeen pediatric critical care medicine fellows were recruited in 2012 and 2013 academic year. INTERVENTIONS: None. All subjects completed an objective structured clinical examination assessment. MEASUREMENTS AND MAIN RESULTS: Seventeen trainees were assessed. Simulation scenarios were developed for content validity by pediatric critical care medicine and education experts using CanMEDS competencies. Scenarios were piloted before the study. Each scenario was evaluated by two interprofessional raters. Inter-rater agreement, measured using intraclass correlations, was 0.91 (SE = 0.09) across stations. Generalizability theory was used to evaluate internal structure and reliability. Reliability was moderate (G-coefficient = 0.67, Φ-coefficient = 0.52). The greatest source of variability was from participant by station variance (40.6%). Pearson correlation coefficients were used to evaluate the relationship of objective structured clinical examination with each traditional assessment instruments: multisource feedback, in-training evaluation report, short-answer questions, and Multidisciplinary Critical Care Knowledge Assessment Program. Performance on the objective structured clinical examination correlated with performance on the Multidisciplinary Critical Care Knowledge Assessment Program (r = 0.52; p = 0.032) and multisource feedback (r = 0.59; p = 0.017), but not with the overall performance on the in-training evaluation report (r = 0.37; p = 0.143) or short-answer questions (r = 0.08; p = 0.767). Consequences were not assessed. CONCLUSION: Validity and feasibility evidence in this study indicate that the use of the objective structured clinical examination scores can be a valid way to assess CanMEDS competencies required for independent practice in pediatric critical care medicine.

The development and implementation of an inter-professional simulation based pediatric acute care curriculum for ward health care providers.

An interprofessional, simulation based, acute care course for ward health care providers was developed and implemented with the objectives of teaching identification of deteriorating patients, practicing crisis resource management and basic life support skills, and using the SBAR (Situation Background Assessment Recommendation) communication tool. Thirty-eight physicians and 51 nurses attended the four separate courses. Nine questions on a 5-point Likert scale and two open-ended questions revealed that over 95% of respondents strongly agreed/agreed that facilitators encouraged active participation, lectures were presented in an interesting manner, and that simulations were useful for practical skills and for practicing communication. Open-ended questions revealed that participants felt more confident, understood the importance of communication, roles, teamwork and valued the day. Based on this evaluation, the program was regarded as feasible and acceptable to all health care providers.

Implementation of a multicenter rapid response system in pediatric academic hospitals is effective.

OBJECTIVES: This is the first large multicenter study to examine the effectiveness of a pediatric rapid response system (PRRS). The primary objective was to determine the effect of a PRRS using a physician-led team on the rate of actual cardiopulmonary arrests, defined as an event requiring chest compressions, epinephrine, or positive pressure ventilation. The secondary objectives were to determine the effect of PRRSs on the rate of PICU readmission within 48 hours of discharge and PICU mortality after readmission and urgent PICU admission. METHODS: A PRRS was developed, implemented, and evaluated in a standardized manner across 4 pediatric academic centers in Ontario, Canada. The team responded to activations for inpatients and followed patients discharged from the PICU for 48 hours. A 2-year, prospective, observational study was conducted after implementation, and outcomes were compared with data collected 2 years before implementation. RESULTS: After PRRS implementation, there were 55 963 hospital admissions and a team activation rate of 44 per 1000 hospital admissions. There were 7302 patients followed after PICU discharge. Implementation of the PRRS was not associated with a reduction in the rate of actual cardiopulmonary arrests (1.9 vs 1.8 per 1000 hospital admissions; P=.68) or PICU mortality after urgent admission (1.3 vs 1.1 per 1000 hospital admissions; P=.25). There was a reduction in the PICU mortality rate after readmission (0.3 vs 0.1 death per 1000 hospital admissions; P=.05). CONCLUSION: The standardized implementation of a multicenter PRRS was associated with a decrease in the rate of PICU mortality after readmission but not actual cardiopulmonary arrests.

Clinically important venous thromboembolism in pediatric critical care: a Canadian survey.

PURPOSE: Pediatric venous thromboembolism (VTE) is becoming an increasingly recognized morbidity associated with critical illness. The objective of this survey is to identify the patient factors and radiological features that pediatric intensivists consider more or less likely to make a venous thrombosis (VTE) clinically important in their patients. MATERIALS AND METHODS: Our definition of clinically important VTE was a VTE likely to result in short- or long-term morbidity or mortality if left untreated. We asked respondents to rate the likelihood that patient factors and radiological features make a venous thrombosis clinically important using a 5-point scale (1 = much less likely to 5 = much more likely). RESULTS: The 38 (58.5%) of 65 pediatric intensivists responding rated 4 patient factors as most likely to make a VTE clinically important: clinical suspicion of pulmonary embolism (mean score, 4.8), symptoms (mean, 4.5), detection by physical exam (mean, 4.4), and the presence of an acute or chronic cardiopulmonary comorbidity that might limit a patient's ability to tolerate pulmonary embolism (mean, 4.3). Of the radiological features, the 2 considered most important were VTE involving the vena cava extending into the right atrium (mean, 5) and central veins (mean, 4.5). CONCLUSIONS: When labeling a VTE as clinically important, pediatric intensivists rely on several specific patient factors and thrombus characteristics.
