Item An investigation into emergency medicine resident cricothyrotomy competency: Is three the magic number?(Wiley, 2023-11-22) Turner, Joseph S.; Stewart, Lauren K.; Hybarger, Andrew C.; Ellender, Timothy J.; Stepsis, Tyler M.; Bartkus, Edward A.; Garverick, Paul, II; Cooper, Dylan D.; Emergency Medicine, School of MedicineObjectives: Cricothyrotomy is a high-stakes emergency procedure. Because the procedure is rare, simulation is often used to train residents. The Accreditation Council for Graduate Medical Education (ACGME) requires performance of three cricothyrotomies during residency, but the optimal number of training repetitions is unknown. Additional repetitions beyond three could increase proficiency, though it is unknown whether there is a threshold beyond which there is no benefit to additional repetition. The objective of this study was to establish a minimum number of simulated cricothyrotomy attempts beyond which additional attempts did not increase proficiency. Methods: This was a prospective, observational study conducted over 3 years at the simulation center of an academic emergency medicine residency program. Participants were residents participating in a cricothyrotomy training as part of a longitudinal airway curriculum course. The primary outcome was time to successful completion of the procedure as first-year residents. Secondary outcomes included time to completion as second- and third-year residents. Procedure times were plotted as a function of attempt number. Data were analyzed using descriptive statistics, repeated-measures analysis of variance, and correlation analysis. Preprocedure surveys collected further data regarding procedure experience, confidence, and comfort. Results: Sixty-nine first-year residents participated in the study. Steady improvement in time to completion was seen through the first six attempts (from a mean of 75 to 41 sec), after which no further significant improvement was found. Second- and third-year residents initially demonstrated slower performance than first-year residents but rapidly improved to surpass their first-year performance. Resident mean times at five attempts were faster with each year of residency (first-year 48 sec, second-year 30 sec, third-year 24 sec). There was no statistically significant correlation between confidence and time to complete the procedure. Conclusions: Additional repetition beyond the ACGME-endorsed three cricothyrotomy attempts may help increase proficiency. Periodic retraining may be important to maintain skills.Item Changing Systems Through Effective Teams: A Role for Simulation(Wiley, 2017) Rosenman, Elizabeth D.; Fernandez, Rosemarie; Wong, Ambrose H.; Cassara, Michael; Cooper, Dylan D.; Kou, Maybelle; Laack, Torrey A.; Motola, Ivette; Parsons, Jessica R.; Levine, Benjamin R.; Grand, James A.; Department of Emergency Medicine, School of MedicineTeams are the building blocks of the healthcare system, with growing evidence linking the quality of health care to team effectiveness, and team effectiveness to team training. Simulation has been identified as an effective modality for team training and assessment. Despite this, there are gaps in methodology, measurement, and implementation that prevent maximizing the impact of simulation modalities on team performance. As part of the 2017 Academic Emergency Medicine Consensus Conference “Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes,” we explored the impact of simulation on various aspects of team effectiveness. The consensus process included an extensive literature review, group discussions, and the conference “work-shop” involving emergency medicine physicians, medical educators, and team science experts. The objectives of this work are to: (1) explore the antecedents and processes that support team effectiveness, (2) summarize the current role of simulation in developing and understanding team effectiveness, and (3) identify research targets to further improve team-based training and assessment, with the ultimate goal of improving health care systems.Item Cross-over study of novice intubators performing endotracheal intubation in an upright versus supine position(Springer, 2016) Turner, Joseph S.; Ellender, Timothy J.; Okonkwo, Enola R.; Stepsis, Tyler M.; Stevens, Andrew C.; Eddy, Christopher S.; Sembroski, Erik G.; Perkins, Anthony J.; Cooper, Dylan D.; Department of Emergency Medicine, IU School of MedicineThere are a number of potential physical advantages to performing orotracheal intubation in an upright position. The objective of this study was to measure the success of intubation of a simulated patient in an upright versus supine position by novice intubators after brief training. This was a cross-over design study in which learners (medical students, physician assistant students, and paramedic students) intubated mannequins in both a supine (head of the bed at 0°) and upright (head of bed elevated at 45°) position. The primary outcome of interest was successful intubation of the trachea. Secondary outcomes included log time to intubation, Cormack–Lehane view obtained, Percent of Glottic Opening score, provider assessment of difficulty, and overall provider satisfaction with the position. There were a total of 126 participants: 34 medical students, 84 physician assistant students, and 8 paramedic students. Successful tracheal intubation was achieved in 114 supine attempts (90.5 %) and 123 upright attempts (97.6 %; P = 0.283). Upright positioning was associated with significantly faster log time to intubation, higher likelihood of achieving Grade I Cormack–Lehane view, higher Percent of Glottic Opening score, lower perceived difficulty, and higher provider satisfaction. A subset of 74 participants had no previous intubation training or experience. For these providers, there was a non-significant trend toward improved intubation success with upright positioning vs supine positioning (98.6 % vs. 87.8 %, P = 0.283). For all secondary outcomes in this group, upright positioning significantly outperformed supine positioning.Item Effect of an Aerosol Box on Intubation in Simulated Emergency Department Airways: A Randomized Crossover Study(University of California, 2020-11) Turner, Joseph S.; Falvo, Lauren E.; Ahmed, Rami A.; Ellender, Timothy J.; Corson-Knowles, Dan; Bona, Anna M.; Sarmiento, Elisa J.; Cooper, Dylan D.; Emergency Medicine, School of MedicineIntroduction: The use of transparent plastic aerosol boxes as protective barriers during endotracheal intubation has been advocated during the severe acute respiratory syndrome coronavirus 2 pandemic. There is evidence of worldwide distribution of such devices, but some experts have warned of possible negative impacts of their use. The objective of this study was to measure the effect of an aerosol box on intubation performance across a variety of simulated difficult airway scenarios in the emergency department. Methods: This was a randomized, crossover design study. Participants were randomized to intubate one of five airway scenarios with and without an aerosol box in place, with randomization of intubation sequence. The primary outcome was time to intubation. Secondary outcomes included number of intubation attempts, Cormack-Lehane view, percent of glottic opening, and resident physician perception of intubation difficulty. Results: Forty-eight residents performed 96 intubations. Time to intubation was significantly longer with box use than without (mean 17 seconds [range 6-68 seconds] vs mean 10 seconds [range 5-40 seconds], p <0.001). Participants perceived intubation as being significantly more difficult with the aerosol box. There were no significant differences in the number of attempts or quality of view obtained. Conclusion: Use of an aerosol box during difficult endotracheal intubation increases the time to intubation and perceived difficulty across a range of simulated ED patients.Item Effect of Socioeconomic Status Bias on Medical Student–Patient Interactions Using an Emergency Medicine Simulation(Wiley, 2017-04) Pettit, Katie E.; Turner, Joseph S.; Kindrat, Jason K.; Blythe, Gregory J.; Hasty, Greg E.; Perkins, Anthony J.; Ashburn-Nardo, Leslie; Milgrom, Lesley B.; Hobgood, Cherri D.; Cooper, Dylan D.; Emergency Medicine, School of MedicineObjectives Implicit bias in clinical decision making has been shown to contribute to healthcare disparities and results in negative patient outcomes. Our objective was to develop a high‐fidelity simulation model for assessing the effect of socioeconomic status (SES) on medical student (MS) patient care. Methods Teams of MSs were randomly assigned to participate in a high‐fidelity simulation of acute coronary syndrome. Cases were identical with the exception of patient SES, which alternated between a low‐SES homeless man and a high‐SES executive. Students were blinded to study objectives. Cases were recorded and scored by blinded independent raters using 24 dichotomous items in the following domains: 13 communication, six information gathering, and five clinical care. In addition, quantitative data were obtained on the number of times students performed the following patient actions: acknowledged patient by name, asked about pain, generally conversed, and touching the patient. Fisher's exact test was used to test for differences between dichotomous items. For continuous measures, group differences were tested using a mixed‐effects model with a random effect for case to account for multiple observations per case. Results Fifty‐eight teams participated in an equal number of high‐ and low‐SES cases. MSs asked about pain control more often (p = 0.04) in patients of high SES. MSs touched the low‐SES patient more frequently (p = 0.01). There were no statistically significant differences in clinical care or information gathering measures. Conclusions This study demonstrates more attention to pain control in patients with higher SES as well as a trend toward better communication. Despite the differences in interpersonal behavior, quantifiable differences in clinical care were not seen. These results may be limited by sample size, and larger cohorts will be required to identify the factors that contribute to SES bias.Item Emergency physician documentation quality and cognitive load : comparison of paper charts to electronic physician documentation(2014) Chisholm, Robin Lynn; Dixon, Brian E.; Cooper, Dylan D.; Doebbeling, Brad; Jones, Josette F.Reducing medical error remains in the forefront of healthcare reform. The use of health information technology, specifically the electronic health record (EHR) is one attempt to improve patient safety. The implementation of the EHR in the Emergency Department changes physician workflow, which can have negative, unintended consequences for patient safety. Inaccuracies in clinical documentation can contribute, for example, to medical error during transitions of care. In this quasi-experimental comparison study, we sought to determine whether there is a difference in document quality, error rate, error type, cognitive load and time when Emergency Medicine (EM) residents use paper charts versus the EHR to complete physician documentation of clinical encounters. Simulated patient encounters provided a unique and innovative environment to evaluate EM physician documentation. Analysis focused on examining documentation quality and real-time observation of the simulated encounter. Results demonstrate no change in document quality, no change in cognitive load, and no change in error rate between electronic and paper charts. There was a 46% increase in the time required to complete the charting task when using the EHR. Physician workflow changes from partial documentation during the patient encounter with paper charts to complete documentation after the encounter with electronic charts. Documentation quality overall was poor with an average of 36% of required elements missing which did not improve during residency training. The extra time required for the charting task using the EHR potentially increases patient waiting times as well as clinician dissatisfaction and burnout, yet it has little impact on the quality of physician documentation. Better strategies and support for documentation are needed as providers adopt and use EHR systems to change the practice of medicine.Item Feasibility of upright patient positioning and intubation success rates at two academic emergency departments(Elsevier, 2017-07) Turner, Joseph S.; Ellender, Timothy J.; Okonkwo, Enola R.; Stepsis, Tyler M.; Stevens, Andrew C.; Sembroski, Erik G.; Eddy, Christopher S.; Perkins, Anthony J.; Cooper, Dylan D.; Emergency Medicine, School of MedicineObjectives Endotracheal intubation is most commonly taught and performed in the supine position. Recent literature suggests that elevating the patient's head to a more upright position may decrease peri-intubation complications. However, there is little data on the feasibility of upright intubation in the emergency department. The goal of this study was to measure the success rate of emergency medicine residents performing intubation in supine and non-supine, including upright positions. Methods This was a prospective observational study. Residents performing intubation recorded the angle of the head of the bed. The number of attempts required for successful intubation was recorded by faculty and espiratory therapists. The primary outcome of first past success was calculated with respect to three groups: 0–10° (supine), 11–44° (inclined), and ≥ 45° (upright); first past success was also analyzed in 5 degree angle increments. Results A total of 231 intubations performed by 58 residents were analyzed. First pass success was 65.8% for the supine group, 77.9% for the inclined group, and 85.6% for the upright group (p = 0.024). For every 5 degree increase in angle, there was increased likelihood of first pass success (AOR = 1.11; 95% CI = 1.01–1.22, p = 0.043). Conclusions In our study emergency medicine residents had a high rate of success intubating in the upright position. While this does not demonstrate causation, it correlates with recent literature challenging the traditional supine approach to intubation and indicates that further investigation into optimal positioning during emergency department intubations is warranted.Item Human factors and simulation in emergency medicine(Wiley, 2017) Hayden, Emily M.; Wong, Ambrose H.; Ackerman, Jeremy; Sande, Margaret K.; Lei, Charles; Kobayashi, Leo; Cassara, Michael; Cooper, Dylan D.; Perry, Kimberly; Lewandowski, William E.; Scerbo, Mark W.; Emergency Medicine, School of MedicineThis consensus group from the 2017 Academic Emergency Medicine Consensus Conference “Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes” held in Orlando, Florida on May 16, 2017 focused on the use of human factors and simulation in the field of emergency medicine. The human factors discipline is often underutilized within emergency medicine but has significant potential in improving the interface between technologies and individuals in the field. The discussion explored the domain of human factors, its benefits in medicine, how simulation can be a catalyst for human factors work in emergency medicine, and how emergency medicine can collaborate with human factors professionals to affect change. Implementing human factors in emergency medicine through healthcare simulation will require a demonstration of clinical and safety outcomes, advocacy to stakeholders and administrators, and establishment of structured collaborations between human factors professionals and emergency medicine, such as in this breakout group.Item Improved simulated ventilation with a novel tidal volume and peak inspiratory pressure controlling bag valve mask: A pilot study(Elsevier, 2023-01-05) Merrell, Jonathan G.; Scott, Adam C.; Stambro, Ryan; Boukai, Amit; Cooper, Dylan D.; Pediatrics, School of MedicineIntroduction: The dangers of hyperventilation during resuscitation are well known. Traditional bag valve mask (BVM) devices rely on end users to control tidal volume (Vt), rate, and peak inspiratory pressures (PIP) of ventilation. The Butterfly BVM (BBVM) is a novel device intending to give greater control over these parameters. The objective of this pilot study was to compare the BBVM against a traditional device in simulated resuscitations. Methods: Senior emergency medicine residents and fellows participated in a three-phase simulation study. First, participants used the Ambu Spur II BVM in adult and pediatric resuscitations. Vt, PIP, and rate were recorded. Second, participants repeated the resuscitations after a brief introduction to the BBVM. Third, participants were given a longer introduction to the BBVM and were tested on their ability to adjust its various settings. Results: Nineteen participants were included in the adult arm of the study, and 16 in the pediatric arm. The BBVM restricted Vt delivered to a range of 4-8 ml/kg vs 9 ml/kg and 13 ml/kg (Ambu adult and Ambu pediatric respectively). The BBVM never exceeded target minute ventilations while the Ambu BVMs exceeded target minute ventilation in 2 of 4 tests. The BBVM failed to reliably reach higher PIP targets in one test, while the pediatric Ambu device had 76 failures of excessive PIP compared to 2 failures by the BBVM. Conclusion: The BBVM exceeded the Ambu Spur II in delivering appropriate Vts and in keeping PIPs below target maximums to simulated adult and pediatric patients in this pilot study.Item Should Children With Acute Asthma Exacerbation Receive Inhaled Anticholinergics?(Elsevier, 2015-01) Cooper, Dylan D.; Welch, Julie L.; Department of Emergency Medicine, IU School of MedicineThe use of inhaled anticholinergics (ipratropium bromide) along with inhaled short-acting β-agonists (albuterol) can reduce hospital admission rates in children with moderate to severe asthma exacerbations.
