BackgroundSimulation has been identified as a means of assessing resident physicians’ mastery of technical skills, but there is a lack of evidence for its utility in longitudinal assessments of residents’ non-technical clinical abilities. We evaluated the growth of crisis resource management (CRM) skills in the simulation setting using a validated tool, the Ottawa Crisis Resource Management Global Rating Scale (Ottawa GRS). We hypothesized that the Ottawa GRS would reflect progressive growth of CRM ability throughout residency.MethodsForty-five emergency medicine residents were tracked with annual simulation assessments between 2006 and 2011. We used mixed-methods repeated-measures regression analyses to evaluate elements of the Ottawa GRS by level of training to predict performance growth throughout a 3-year residency.ResultsOttawa GRS scores increased over time, and the domains of leadership, problem solving, and resource utilization, in particular, were predictive of overall performance. There was a significant gain in all Ottawa GRS components between postgraduate years 1 and 2, but no significant difference in GRS performance between years 2 and 3.ConclusionsIn summary, CRM skills are progressive abilities, and simulation is a useful modality for tracking their development. Modification of this tool may be needed to assess advanced learners’ gains in performance.
IntroductionIn-hospital cardiac arrest (IHCA) is a particularly vexing entity from the perspective of preparedness, as it is neither common nor truly rare. Survival from IHCA requires the coordinated efforts of multiple providers with different skill sets who may have little prior experience working together. Survival rates have remained low despite advances in therapy, suggesting that human factors may be at play.Methods and analysisThis qualitative study uses a quasiethnographic data collection approach combining focus group interviews with providers involved in IHCA resuscitation as well as analysis of video recordings from in situ-simulated cardiac arrest events. Using grounded theory-based analysis, we intend to understand the organisational, interpersonal, cognitive and behavioural dimensions of IHCA resuscitation, and to build a descriptive model of code team functioning.Ethics and disseminationThis ongoing study has been approved by the IRB at UC Davis Medical Center.ResultsThe results will be disseminated in a subsequent manuscript.
IntroductionIn-hospital cardiac arrest (IHCA) affects 200 000 adults in the USA each year, and resuscitative efforts are often suboptimal. The objective of this study was to determine whether a programme of ‘mock codes’ improves group-level performance of IHCA skills. Our primary outcome of interest was change in cardiopulmonary resuscitation (CPR) fraction, and the secondary outcomes of interest were time to first dose of epinephrine and time to first defibrillation. We hypothesised that a sustained programme of mock codes would translate to greater than 10% improvement in each of these core metrics over the first 3 years of the programme.MethodsWe conducted mock codes in an urban teaching hospital between August 2012 and October 2015. Mock codes occurred on Telemetry and Medical/Surgical units on day and night shifts. Codes were managed by unit staff and members of the hospital’s ‘Code Blue’ team, and data were recorded by trained observers. Data were summarised using descriptive statistics, and repeated measures outcomes were calculated using a mixed effects model.ResultsFifty-seven mock codes were included in the analysis: 42 on Medical/Surgical units and 15 on Telemetry units. CPR fraction increased by 2.9% per 6-month time interval on Telemetry units, and 1.3% per time interval on Medical/Surgical units. Neither time to first epinephrine dosing nor time to defibrillation changed significantly.ConclusionsWhile we observed a significant improvement in CPR fraction over the course of this programme of mock codes, similar improvements were not observed for other key measures of cardiac arrest performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
