    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 Medicine
    Objectives: 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.

    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 Medicine
    There 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.

    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 Medicine
    Objectives 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.
