Level of Awareness of Certified Non-critical Care Physicians in Diagnosing, Managing, and Disposing Anaphylactic Cases.

Background: Anaphylaxis is known as an acute, severe hypersensitivity reaction that rapidly initiates after exposure to a triggering agent. It is a life-threatening condition, and early recognition and swift intervention are crucial to saving patients' lives. Objective: The objective of this study is to assess the ability of certified non-critical care physicians to recognize, manage, and dispose cases of anaphylaxis. Methods: A survey consisting of 19 questions was developed by expert emergency consultants to evaluate physicians' knowledge regarding the recognition, management, and disposition of anaphylactic episodes. Responses were collected through in-person surveys conducted with physicians from various specialties and varying clinical experience levels at a tertiary care center in the Eastern Province of Saudi Arabia. Results: In this cross-sectional study, a total of 173 physicians completed the survey, with 81.5% being consultants and 18.5% specialists. Only 5.2% correctly identified all three proposed anaphylaxis clinical scenarios, 16.8% identified two scenarios correctly, and 51.4% identified only one scenario. While 42.8% recognized the first-line management of anaphylaxis, only 24.3% and 24.9% knew the correct epinephrine dose and route, respectively. Regarding the disposition of patients experiencing an anaphylactic episode, 61.9% of responders opted to dispose the case to the emergency department. Conclusion: Our study reveals a knowledge gap among non-critical care physicians practicing in a tertiary care center concerning the identification and management of anaphylaxis. Raising awareness of this life-threatening condition is imperative to address this serious issue.

Application of Automated External Defibrillators Among the Public: A Cross-Sectional Study of Knowledge, Attitude, Practice, and Barriers of Use in Saudi Arabia.

Background: The likelihood of survival of an out-of-hospital cardiac arrest quadruples with the rapid application of basic life support (BLS). The public's ability to perform cardiopulmonary resuscitation (CPR) and use automated external defibrillators (AEDs) is extremely important. This study aimed to assess the public knowledge, attitudes, and practices (KAP) of utilizing AEDs and to understand barriers to AED application. Methods: We conducted a cross-sectional study from March 1-30, 2022. An electronic questionnaire was constructed and validated to measure the KAP for public AED utilization and its barriers. Results: Of the 406 participants, 244 (60.10%) were males. Male respondents had 17% less knowledge and poorer attitude towards using an AED as compared to female respondents. Knowledge and attitudes on using AEDs were low (70.7%) among Saudi nationals compared to those of foreign nationals. Those who were BLS/CPR trained had a 2.5 times greater understanding and willingness to use AEDs in public than those who were not. Barriers to AEDs in CPR/BLS-trained participants were: (1) accidentally hurting the victim (14.3%), (2) duty as a bystander to just call the ambulance and wait for help (12.1%), (3) never taught what to do (n = 41, 18.4%), (4) did not want to be scolded if performed wrong (3.1%), and (5) never witnessed such a situation (51.6%). Conclusion: There is a strong association between knowledge of and willingness to use AEDs in emergency situations among the public. Misconceptions about AEDs hinder their use. This calls for urgent training programs through accessible technology to reach the public.

Prevalence of COVID-19 Among Patients Arriving in Pre-arrest/Cardiac Arrest, at a Tertiary Hospital's ED in the Eastern Province of Saudi Arabia During the COVID-19 Pandemic.

Background: COVID-19 pandemic has thrown the healthcare systems into confusion worldwide, resulting in major modifications on the practice due to fear of exposure to this virus and its fatal consequences. Objective: the study aimed to establish the prevalence of COVID-19 in cardiac arrest patients. Methods: single-centered, Retrospective, observational cohort study that included all patients who presented to ED during the period of the pandemic from January 2021 to May 2022 and documented to have either IN-hospital cardiac arrest (IHCA), specifically within the ED, or OUT-hospital cardiac arrest (OHCA). Results: This study analyzed 177 patients. Out of which, 30.5% of the patients were aged more than 70 years old. Those with associated comorbidities, the most frequently mentioned comorbidity was hypertension (40.7%). It was found that the prevalence of positive COVID-19 infection was significantly more common among non-Arab (p=0.019), patients with associated chronic kidney disease (p=0.019) and those who had an in-hospital cardiac arrest (p=0.010). No significant associations were observed between COVID-19 infection in terms of age, gender, nationality, associated comorbidities, symptoms, and trauma (all p>0.05). Conclusion: This study showed the prevalence of COVID-19 among cardiac arrest patients within ED and outside the hospital in our study population. Based on the study's results, the major adjustments in practice were not absolutely needed. Also, this study could help in establishing a good mitigation strategy for at-risk patients.

A Cerebrovascular Incident Secondary to Extensive Aortic Arch Atheroma.

Plaques can form across different parts of the aorta, from the aortic arch to the thoracic and abdominal aorta. Aortic arch atheroma, however, is highly associated with cerebrovascular insults due to their dislodgement. Although no concise management protocol has been defined for dealing with such presentations, antiplatelet agents and anticoagulants are most frequently used. In this case, we present a 78-year-old male with a known case of diabetes mellitus type 2, hypertension, and dyslipidemia who presented to the emergency department with acute onset of slurred speech. A CT angiography was performed that revealed extensive plaque formations across the aortic arch with a 90% occlusion of the distal left common carotid artery and carotid bifurcation along with 99% stenosis of the internal carotid artery. The patient underwent aspiration thrombectomy and was started on dual antiplatelets but passed away after developing decompensated heart failure.

Disaster health education framework for short and intermediate training in Saudi Arabia: A scoping review.

Background: Saudi Arabia has made extensive efforts to manage disasters using unique national approaches; however, challenges and obstacles concerning disaster health handling persist. The nation has a reactive strategy to disaster management with a need for increased involvement of health professionals in disaster management and improvement of healthcare facilities emergency preparedness including competency-based education training. Objective: A comprehensive and consistent approach of disaster education programs for short and intermediate training of health professionals involved in disaster responses in Saudi Arabia is still not evident. Therefore, it is vital to explore and map the current state of the disaster education framework in Saudi Arabia. Methods: The Joanna Briggs Institute approach for scoping reviews was used to assess research articles and preprints between January 2000 and September 2021 from Saudi Digital Library; PubMed, CINAHL, and Google Scholar. Five experts identified key aspects of the disaster education approach and eligibility criteria to facilitate identification of relevant articles. Results: Only five articles met the specified criteria and described two short and three intermediate courses on disaster health management in Saudi Arabia. All courses involved competency-specific training aimed at basic or foundational level and involved a range of activities and learning types. None had refresher courses within 12 months. Conclusion: The review highlights the obvious scarcity of short and intermediate term evidence-based disaster health programs in Saudi Arabia. Adoption of the education framework proposed by the authors based on international frameworks could improve the quality and consistency of the disaster education curriculum in Saudi Arabia.

Assessment of the effectiveness of a course in major chemical incidents for front line health care providers: a pilot study from Saudi Arabia.

BACKGROUND: Mass chemical exposure emergencies are infrequent but can cause injury, illness, or loss of life for large numbers of victims. These emergencies can stretch and challenge the available resources of healthcare systems within the community. Political unrest in the Middle East, including chemical terrorist attacks against civilians in Syria and increasing chemical industry accidents, have highlighted the lack of hospital preparedness for chemical incidents in the region. This study aimed to evaluate the effectiveness of a course designed to empower frontline healthcare providers involved in mass casualty incidents with the basic knowledge and essential operational skills for mass chemical exposure incidents in Saudi Arabia. METHODS: A mixed-methods approach was used to develop a blended learning, simulation enhanced, competency-based course for major chemical incidents for front line healthcare providers. The course was designed by experts from different disciplines (disaster medicine, poisoning / toxicology, and Hazard Material Threat - HAZMAT team) in four stages. The course was piloted over five days at the Officers Club of the Ministry of Interior (Riyadh, Saudi Arabia). The 41 participants were from different government health discipline sectors in the country. Pre- and post-tests were used to assess learner knowledge while debriefing sessions after the decontamination triage session and simulation-enhanced exercises were used for team performance assessment. RESULTS: The overall knowledge scores were significantly higher in the post-test (69.47%) than the pre-test (46.3%). All four knowledge domains also had significant differences between pre- and post-test results. There were no differences in the pre and post-test scores for healthcare providers from the different health disciplines. A one-year post-event survey demonstrated that participants were satisfied with their knowledge retention. Interestingly, 38.3% had the opportunity to put this knowledge into practice in relation to mass chemical exposure incidents. CONCLUSION: Delivering a foundation level competency-based blended learning course with enhanced simulation training in major chemical incidents for front line healthcare providers may improve their knowledge and skills in response to such incidents. This in turn can improve the level of national preparedness and staff availability and make a crucial difference in reducing the health impacts among victims.

Negative Whole-Body Computed Tomography Scans in Polytrauma Patients: A Retrospective Cohort Study.

BACKGROUND: Whole-body computed tomography (WBCT) has been a mainstay and an integral part of the evaluation of polytrauma patients in trauma centers and emergency departments (ED) for a comprehensive evaluation of the extent of injuries. However, routine use of WBCT remains controversial since it exposes patients to radiation and exponentially increases financial expense. The primary objective was to determine the rate of negative WBCT in polytrauma patients. PATIENTS AND METHODS: A retrospective cohort study was conducted at an academic hospital in the Kingdom of Saudi Arabia, which is a dedicated trauma center with a mean of 237,392 ED visits and 10,714 trauma per year. The study included all adult (≥18 years) polytrauma patients who presented to our ED, requiring trauma team activation, and underwent WBCT as part of their evaluation from January 2016 to May 2017. We excluded pediatric patients, patients transferred from another facility, and pregnant patients. The primary endpoint was to measure the rate of negative WBCT in polytraumatized patients. RESULTS: A total of 186 patients were included with a mean age of 28.8 ± 12.9 years. The rate of negative WBCT scans was 20.4%. The positive scans were subclassified based on the number of anatomical body regions that were affected radiologically. One body region was affected in 47 patients (31.8%), two body regions were affected in 50 patients (33.8%), and ≥3 body regions were affected in 51 patients (34.3%). In a subset analysis, we identified that oxygen saturation <94% and GCS ≤8 were associated with positive CT scans. CONCLUSION: Our study revealed a slightly higher rate of utilization of WBCT in the management of trauma patients compared to studies with similar practice. We believe that in the correct setting with incorporating high index of suspicion, a physical examination with attention to vital signs and mental status, performing E-FAST, and dedicated X-Rays is a way to potentially reduce the use of WBCT in polytrauma patients.

The Effect of a Multidisciplinary Trauma Team Leader Paradigm at a Tertiary Trauma Center: 10-Year Experience.

BACKGROUND: To illustrate the impact of the implementation of a multidisciplinary TTL program in 2005 on the mortality of trauma patients in a level 1 trauma center as well as admission rates and length of stay. METHODS: Retrospective observational study of all trauma patients included in the provincial trauma database at the Montreal General Hospital between 1998 and 2015. The primary outcome studied was in-hospital mortality. The secondary outcomes studied were hospital and intensive care unit (ICU) rates of admission and hospital and ICU length of stay. RESULTS: 24,107 patients were included. We observed a statistically significant reduction in mortality of 1.25% or a relative reduction of 16% (p value = 0.0058; rate ratio 0.844 (95% CI 0.747-0.952)). ICU admissions were also significantly reduced where we observed a statistically significant absolute reduction of 4.46% or a relative reduction of 14% (p value = 8.38 × 10-7; rate ratio 0.859 (95% CI 0.808-0.912)). The ICU length of stay was increased by 0.91 days or 19.03% (p value = 0.016 (95% CI 0.167-1.655)). There was no observed change in overall length of stay (13.97 days pre-TTL and 12.91 post-TTL (p value = 0.13; estimate -1.053 (95% CI -2.424-0.318))). CONCLUSIONS: This article suggests that multidisciplinary TTL model may be beneficial in the care of trauma patients. Further subgroup analysis may help determine which patients could benefit more.

Comparison of Electronic Versus Manual Mass-Casualty Incident Triage.

IntroductionMass-casualty incidents (MCIs) easily overwhelm a health care facility's human and material resources through the extraordinary influx of casualties. Efficient and accurate triage of incoming casualties is a critical step in the hospital disaster response.Hypothesis/ProblemTraditionally, triage during MCIs has been manually performed using paper cards. This study investigated the use of electronic Simple Triage and Rapid Treatment (START) triage as compared to the manual method. METHODS: This observational, crossover study was performed during a live MCI simulation at an urban, Canadian, Level 1 trauma center on May 26, 2016. Health care providers (two medical doctors [MDs], two paramedics [PMs], and two registered nurses [RNs]) each triaged a total of 30 simulated patients - 15 by manual (paper-based) and 15 by electronic (computer-based) START triage. Accuracy of triage categories and time of triage were analyzed. Post-simulation, patients and participating health care providers also completed a feedback form. RESULTS: There was no difference in accuracy of triage between the electronic and manual methods overall, 83% and 80% (P=1.0), between providers or between triage categories. On average, triage time using the manual method was estimated to be 8.4 seconds faster (P<.001) for PMs; and while small differences in triage times were observed for MDs and RNs, they were not significant. Data from the participant feedback survey showed that the electronic method was preferred by most health care providers. Patients had no preference for either method. However, patients perceived the computer-based method as "less personal" than the manual triage method, but they also perceived the former as "better organized." CONCLUSION: Hospital-based electronic START triage had the same accuracy as hospital-based manual START triage, regardless of triage provider type or acuity of patient presentations. Time of triage results suggest that speed may be related to provider familiarity with a modality rather than the modality itself. Finally, according to patient and provider perceptions, electronic triage is a feasible modality for hospital triage of mass casualties. Further studies are required to assess the performance of electronic hospital triage, in the context of a rapid surge of patients, and should consider additional efficiencies built in to electronic triage systems. This study presents a framework for assessing the accuracy, triage time, and feasibility of digital technologies in live simulation training or actual MCIs.

A hospital mass casualty exercise using city buses and a tent as a hybrid system for patient decontamination.

OBJECTIVE: A hospital mass casualty simulation exercise testing feasibility of two city buses and a tent as a hybrid system for patient decontamination. DESIGN: Observational study of a single mass casualty simulation exercise involving patient decontamination SETTING: Held on May 26, 2016 at the Montreal General Hospital, a Level 1 Trauma center without a garage. PATIENTS, PARTICIPANTS: Twenty-one medical staff including nurses, doctors, and patient attendants, and 30 volunteer-simulated patients. INTERVENTIONS: The foregrounds of the hospital were cordoned off to create a single-entry point for the simulated patients that were identified as contaminated (C) by staff wearing personal protective equipment. Non-contaminated patients were directed to a separate hospital entrance. C patients were triaged in Bus 1 to determine priority for decontamination. Bus 2 served as a holding area for stable patients awaiting decontamination. Patients were decontaminated in appropriate tent sections (non-ambulatory, ambulatory male or female) and then directed to the emergency department. RESULTS: Direct observation and participant feedback suggested that buses may provide adequate shelter for C patients. However, buses had limited capacity for non-ambulatory patients, who were not easily transported inside. Furthermore, areas of improvement were identified in communication, staffing, equipment, and coordination of operations. CONCLUSIONS: The use of city buses as triage and waiting zones prior to decontamination appears feasible for centers without a garage and facing unpredictable weather conditions. Further simulations are required for fine-tuning and testing real-time unfolding of tasks, ideally during an unannounced exercise.

Emergency airway management: the difficult airway.

Patients requiring airway management in the emergency department present an enormous challenge. It requires not only a firm concept of techniques for securing the airway but also of dealing with the potential difficult airway (DA) in which establishing a definite airway is not possible with techniques routinely used. This article highlights the importance of recognition and management of the DA in emergent situations. Both awake and nonawake intubation are discussed, and indications and guidelines are given for the use of nonsurgical and surgical airway interventions.
