Retrospective Study of Midazolam Protocol for Prehospital Behavioral Emergencies
Introduction: Agitated patients in the prehospital setting pose challenges for both patient care and emergency medical services (EMS) provider safety. Midazolam is frequently used to control agitation in the emergency department setting; however, limited data exist in the prehospital setting. We describe our experience treating patients with midazolam for behavioral emergencies in a large urban EMS system. We hypothesized that using midazolam for acute agitation leads to improved clinical conditions without causing significant clinical deterioration.Methods: We performed a retrospective review of EMS patient care reports following implementation of a behavioral emergencies protocol in a large urban EMS system from February 2014–June 2016. For acute agitation, paramedics administered midazolam 1 milligram (mg) intravenous (IV), 5 mg intramuscular (IM), or 5 mg intranasal (IN). Results were analyzed using descriptive statistics, Levene’s test for assessing variance among study groups, and t-test to evaluate effectiveness based on route.Results: In total, midazolam was administered 294 times to 257 patients. Median age was 30 (interquartile range 24–42) years, and 66.5% were male. Doses administered were 1 mg (7.1%) and 5 mg (92.9%). Routes were IM (52.0%), IN (40.8%), and IV (7.1%). A second dose was administered to 37 patients. In the majority of administrations, midazolam improved the patient’s condition (73.5%) with infrequent adverse events (3.4%). There was no significant difference between the effectiveness of IM and IN midazolam (71.0% vs 75.4%; p = 0.24).Conclusion: A midazolam protocol for prehospital agitation was associated with reduced agitation and a low rate of adverse events
Prehospital intranasal glucagon for hypoglycemia
Background: Prehospital hypoglycemia is usually treated with oral or intravenous (IV) dextrose in a variety of concentrations. In the absence of vascular access, intramuscular (IM) glucagon is commonly administered. Occupational needle-stick injury remains a significant risk while attempting to obtain vascular access or administer medications intramuscularly in the prehospital setting. We sought to determine if intranasal (IN) glucagon is effective in the prehospital treatment of hypoglycemia.
Methods: We performed a retrospective analysis of all consecutive cases where recombinant glucagon was administered IN by paramedics from January 1, 2015 through December 31, 2020. Excluded were cases without pre or post administration blood glucose documentation, and cases where another form of treatment for hypoglycemia was administered at any time during the EMS encounter. The primary outcome was clinical response to IN glucagon documented by paramedics; secondary outcomes included pre and post administration blood glucose values.
Results: Out of 44 cases that met study inclusion criteria, 14 patients (32%) had substantial improvement, 13 patients (30%) had slight improvement, and 17 patients (38%) had no improvement in mental status after administration of IN glucagon. In cases with substantial improvement (n = 14), the mean pre administration blood glucose was 33.8 mg/dl and the mean post administration blood glucose was 87.1 mg/dl (mean increase 53.3 mg/dl, 95% CI: 21.5 to 85.1). In cases with slight improvement (n = 13), the mean pre administration blood glucose was 23.9 mg/dl and the mean post administration blood glucose was 53.8 mg/dl (mean increase 29.9 mg/dl, 95% CI = 2.9 to 56.9). In case with no improvement (n = 17) the mean pre administration blood glucose was 30.1 mg/dl and the mean post administration glucose was 33.1 mg/dl (mean difference 3.1 mg/dl, 95% CI: -10.1 to 3.9).
Conclusion: Intranasal administration of recombinant glucagon for hypoglycemia resulted in a clinically significant improvement in mental status and a corresponding increase in blood glucose levels in select cases in the prehospital setting

Creation and Implementation of a Mastery Learning Curriculum for Emergency Department Thoracotomy
Introduction: Emergency department thoracotomy (EDT) is a lifesaving procedure within the scope of practice of emergency physicians. Because EDT is infrequently performed, emergency medicine (EM) residents lack opportunities to develop procedural competency. There is no current mastery learning curriculum for residents to learn EDT. The purpose of this study was to develop and implement a simulation-based mastery learning curriculum to teach and assess EM residents’ performance of the EDT.Â
Methods: We developed an EDT curriculum using a mastery learning framework. The minimum passing standard (MPS) for a previously developed 22-item checklist was determined using the Mastery Angoff approach. EM residents at a four-year academic EM residency program underwent baseline testing in performing an EDT on a simulation trainer. Performance was scored by two raters using the checklist. Learners then participated in a novel mastery learning EDT curriculum that included an educational video, hands-on instruction, and deliberate practice. After a three-month period, residents then completed initial post testing. Residents who did not meet the minimum passing standard after post testing participated in additional deliberate practice until mastery was obtained. Baseline and post-test scores, and time to completion of the procedure were compared with paired t-tests.Results: Of 56 eligible EM residents, 54 completed baseline testing. Fifty-two residents completed post-testing until mastery was reached. The minimum passing standard was 91.1%, (21/22 items correct on the checklist). No participants met the MPS at the baseline assessment. After completion of the curriculum, all residents subsequently reached the MPS, with deliberate practice sessions not exceeding 40 minutes. Scores from baseline testing to post-testing significantly improved across all postgraduate years from a mean score of 10.2/22 to 21.4/22 (p <0.001). Mean time to complete the procedure improved from baseline testing (6 minutes [min] and 21 seconds [sec], interquartile range [IQR] = 4 min 54 sec - 7 min 51 sec) to post-testing (5 min 19 seconds, interquartile range 4 min 17sec - 6 min 15 sec; p = 0.001).Conclusion: This simulation-based mastery learning curriculum resulted in all residents performing an EDT at a level that met or exceeded the MPS with an overall decrease in time needed to perform the procedure
