Search and Rescue in California: The Need for a Centralized Reporting System.

INTRODUCTION: There is no published information on the epidemiology of wilderness rescues in California outside of national parks. The objective of this study was to investigate the epidemiology of wilderness search and rescue (SAR) missions in California and identify risk factors for individuals requiring rescue due to accidental injury, illness, or navigation errors in the California wilderness. METHODS: A retrospective review of SAR missions in California from 2018 to 2020 was conducted. This was done from a database of information collected by the California Office of Emergency Services and the Mountain Rescue Association from SAR teams, who submitted voluntarily. The subject demographics, activity, location, and outcomes of each mission were analyzed. RESULTS: Eighty percent of the initial data were excluded because of incomplete or inaccurate data. Seven hundred forty-eight SAR missions involving 952 subjects were included in the study. The demographics, activities, and injuries of our population were consistent with those reported from other epidemiological SAR studies, and there were significant differences in outcomes based on the subject's activity. For example, water activities were highly correlated with a fatal outcome. CONCLUSIONS: The final data show interesting trends, but it is difficult to draw firm conclusions because so much of the initial data had to be excluded. A uniform system for reporting SAR missions in California may be helpful for further research, which may aid both SAR teams and the recreational public in understanding risk factors. A proposed SAR form for easy entry is included in the discussion section.

Multiple Hospital In-Situ Mass Casualty Incident Training Simulation for Emergency Medicine Residents: A Sarin Bomb Scenario.

INTRODUCTION: We simulated an on-site, multi-hospital mass casualty incident (MCI) to educate emergency medicine providers in the principles of trauma resuscitation and collaboration with administration and staff during an MCI. METHODS: We implemented high-fidelity manikins, inflatable manikins, and actors to simulate a sarin gas bombing. Learners triaged patients at a decontamination tent using the simple triage and rapid treatment (START) tool, or they participated in a simulation in a resuscitation bay. RESULTS: Forty participants anonymously rated the learning impact of the exercise, the clinical relevance to emergency medicine, and the effectiveness of the faculty facilitation and debriefing on a 1-5 Likert scale. The average responses to all questions were 4.45 or greater, and 98% of respondents recommended adding the scenario to the standard curriculum. DISCUSSION: We successfully executed a novel, multi- hospital, MCI drill that was rated to be a better alternative to sequential simulation in a simulation center.

Assessing the impact of an emergency trauma course for senior medical students in Kenya.

INTRODUCTION: Ninety percent of all injury-related deaths occur in low- and middle-income countries. The WHO recommends short, resource-specific trauma courses for healthcare providers. Studies show that teaching trauma courses to medical students in developed countries leads to significant increases in knowledge and skill. High costs hinder widespread and sustained teaching of these courses in low-income countries. METHODS: A two-day trauma course was designed for students at Moi College of Health Sciences in Eldoret, Kenya. Participants underwent pre- and post-course written and simulation testing and rated their confidence in 21 clinical scenarios and 15 procedures pre- and post-course using a five point Likert scale. A subset of the students was re-evaluated nine months post-course. Using the paired t-test, mean written, simulation and confidence scores were compared pre-course, immediately post-course and nine months post-course. RESULTS: Twenty-two students were enrolled. Written test score means were 61.5% pre-course and 76.9% post-course, mean difference 15.5% (p < 0.001). Simulation test score means were 36.7% pre-course and 82.2% post-course, mean difference 45.5% (p < 0.001). Aggregate confidence scores were 3.21 pre-course and 4.72 post-course (scale 1-5). Ten out of 22 (45.5%) students were re-evaluated nine months post-course. Results showed written test score mean of 75%, simulation score mean of 61.7%, and aggregate confidence score of 4.59 (scale 1-5). Mean differences between immediate post- and nine months post-course were 1.6% (p = 0.75) and 8.7% (p = 0.10) for the written and simulation tests, respectively. CONCLUSION: Senior Kenyan medical students demonstrated statistically significant increases in knowledge, skills and confidence after participating in a novel student trauma course. Nine months post-course, improvements in knowledge skills and confidence were sustained.

Comparison of sudden cardiac arrest resuscitation performance data obtained from in-hospital incident chart review and in situ high-fidelity medical simulation.

INTRODUCTION: High-fidelity medical simulation of sudden cardiac arrest (SCA) presents an opportunity for systematic probing of in-hospital resuscitation systems. Investigators developed and implemented the SimCode program to evaluate simulation's ability to generate meaningful data for system safety analysis and determine concordance of observed results with institutional quality data. METHODS: Resuscitation response performance data were collected during in situ SCA simulations on hospital medical floors. SimCode dataset was compared with chart review-based dataset of actual (live) in-hospital resuscitation system performance for SCA events of similar acuity and complexity. RESULTS: 135 hospital personnel participated in nine SimCode resuscitations between 2006 and 2008. Resuscitation teams arrived at 2.5+/-1.3 min (mean+/-SD) after resuscitation initiation, started bag-valve-mask ventilation by 2.8+/-0.5 min, and completed endotracheal intubations at 11.3+/-4.0 min. CPR was performed within 3.1+/-2.3 min; arrhythmia recognition occurred by 4.9+/-2.1 min, defibrillation at 6.8+/-2.4 min. Chart review data for 168 live in-hospital SCA events during a contemporaneous period were extracted from institutional database. CPR and defibrillation occurred later during SimCodes than reported by chart review, i.e., live: 0.9+/-2.3 min (p<0.01) and 2.1+/-4.1 min (p<0.01), respectively. Chart review noted fewer problems with CPR performance (simulated: 43% proper CPR vs. live: 98%, p<0.01). Potential causes of discrepancies between resuscitation response datasets included sample size and data limitations, simulation fidelity, unmatched SCA scenario pools, and dissimilar determination of SCA response performance by complementary reviewing methodologies. CONCLUSION: On-site simulations successfully generated SCA response measurements for comparison with live resuscitation chart review data. Continued research may refine simulation's role in quality initiatives, clarify methodologic discrepancies and improve SCA response.
