RESUMEN
This is the sixth annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. This summary addresses the most recently published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. Topics covered by systematic reviews include cardiopulmonary resuscitation during transport; approach to resuscitation after drowning; passive ventilation; minimizing pauses during cardiopulmonary resuscitation; temperature management after cardiac arrest; use of diagnostic point-of-care ultrasound during cardiac arrest; use of vasopressin and corticosteroids during cardiac arrest; coronary angiography after cardiac arrest; public-access defibrillation devices for children; pediatric early warning systems; maintaining normal temperature immediately after birth; suctioning of amniotic fluid at birth; tactile stimulation for resuscitation immediately after birth; use of continuous positive airway pressure for respiratory distress at term birth; respiratory and heart rate monitoring in the delivery room; supraglottic airway use in neonates; prearrest prediction of in-hospital cardiac arrest mortality; basic life support training for likely rescuers of high-risk populations; effect of resuscitation team training; blended learning for life support training; training and recertification for resuscitation instructors; and recovery position for maintenance of breathing and prevention of cardiac arrest. Members from 6 task forces have assessed, discussed, and debated the quality of the evidence using Grading of Recommendations Assessment, Development, and Evaluation criteria and generated consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections, and priority knowledge gaps for future research are listed.

BACKGROUND AND AIM: Upper gastrointestinal bleeding (UGIB) is a common emergency, with high rates of hospitalization and in-patient mortality compared to other gastrointestinal diseases. Despite readmission rates being a common quality metric, little data are available for UGIBs. This study aimed to determine readmission rates for patients discharged following an UGIB. METHODS: Adhering to PRISMA guidelines, MEDLINE, Embase, CENTRAL, and Web of Science were searched to October 16, 2021. Randomized and non-randomized studies that reported hospital readmission for patients following an UGIB were included. Abstract screening, data extraction, and quality assessment were conducted in duplicate. A random-effects meta-analysis was performed, with statistical heterogeneity measured using I2 . The GRADE framework, with a modified Downs and Black tool, was used to determine certainty of evidence. RESULTS: Seventy studies were included of 1847 screened abstracted, with moderate interrater reliability. Within these studies, 4 292 714 patients were analyzed with a mean age of 66.6 years, and 54.7% male. UGIB had a 30-day all-cause readmission rate of 17.4% (95% confidence interval [CI] 16.7-18.2%), stratification revealed a higher rate for variceal UGIB [19.6% (95% CI 17.6-21.5%)] than non-variceal [16.8% (95% CI 16.0-17.5%)]. Only one third were readmitted due to recurrent UGIB (4.8% [95% CI 3.1-6.4%]). UGIB due to peptic ulcer bleeding had the lowest 30-day readmission rate [6.9% (95% CI 3.8-10.0%)]. Certainty of evidence was low or very low for all outcomes. CONCLUSIONS: Almost one in five patients discharged after an UGIB are readmitted within 30 days. These data should prompt clinicians to reflect on their own practice to identify areas of strength or improvement.

BACKGROUND: Drowning accounts for hundreds of preventable deaths in Canada every year, but the impact of preexisting medical conditions on the likelihood of death from drowning is not known. We aimed to describe the prevalence of pre-existing medical conditions among people who fatally drowned in Canada and evaluate the risk of fatal drowning among people with common pre-existing medical conditions. METHODS: We reviewed all Canadian unintentional fatal drownings (2007-2016) in the Drowning Prevention Research Centre Canada's database. For each fatal drowning we established whether the person had pre-existing medical conditions and whether those conditions contributed to the drowning. We calculated relative risk (RR) of fatal drowning stratified by age and sex for each pre-existing medical condition using data from the Canadian Chronic Disease Surveillance System. RESULTS: During 2007-2016, 4288 people fatally drowned unintentially in Canada, of whom one-third had a pre-existing medical condition. A pre-existing medical condition contributed to drowning in 43.6% (n = 616) of cases. Fatal drowning occurred more frequently in people with ischemic heart disease (RR 2.7, 95% confidence interval [CI] 2.5-3.0) and seizure disorders (RR 6.3, 95% CI 5.4-7.3) but less frequently in people with respiratory disease (RR 0.12, 95% CI 0.10-0.15). Females aged 20-34 years with a seizure disorder had a 23 times greater risk than their age- and sex-matched cohort (RR 23, 95% CI 14-39). In general, fatal drowning occurred more often while people were bathing (RR 5.9, 95% CI 4.8-7.0) or alone (RR 1.99, 95% CI 1.32-2.97) and less often in males (RR 0.92, 95% CI 0.88-0.95) or in those who had used alcohol (RR 0.72, 95% CI 0.65-0.80), among those with pre-existing medical conditions. INTERPRETATION: The risk of fatal drowning is increased in the presence of some preexisting medical conditions. Tailored interventions aimed at preventing drowning based on pre-existing medical conditions and age are needed. Initial prevention strategies should focus on seizure disorders and bathtub drownings.

STUDY OBJECTIVE: Unnecessary computed tomography (CT) scans burden the health care system, leading to increased emergency department (ED) wait times and lengths of stay, costing almost a billion dollars annually. This study aimed to describe ED-based interventions that are most effective at reducing CT imaging while maintaining diagnostic accuracy and patient safety. METHODS: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials, and Google Scholar were searched until December 31, 2020. Randomized and nonrandomized studies that assessed the effect of an ED-based intervention on CT scan usage were included. Abstract screening, data extraction, and quality assessment were conducted in duplicate. The Grading of Recommendation Assessment, Development and Evaluation framework, with the Risk of Bias 2 and Risk of Bias in Nonrandomized Studies - of Interventions tools, was used to determine the certainty of evidence. Significant clinical and statistical heterogeneity precluded meta-analysis; hence, a narrative synthesis was conducted. RESULTS: A total of 149 studies were included of 5,667 screened abstracts, with substantial interrater reliability among reviewers (Cohen's κ>0.60). The CT reduction strategies were categorized into 15 single and 11 multimodal interventions by consensus review. Interventions that consistently reduced CT usage included diagnostic pathways, alternative test availability, specialist involvement, and provider feedback. Family/patient education, clinical decision support tools, or passive guideline dissemination did not consistently reduce usage. Only 44% of studies reported unintended consequences of reduction strategies; however, these showed no increase in missed diagnoses or patient harm. The interventions that engaged multiple specialties during planning/implementation had a greater reduction effect than ED only. The certainty of evidence for the primary outcome was very low. CONCLUSION: Multidisciplinary-led interventions that provided an alternative to CT imaging were the most effective at reducing usage and did so without compromising patient safety.

AIM: To quantify the associations of foreign body airway obstruction (FBAO) basic life support (BLS) interventions with FBAO relief and survival to discharge. METHODS: We identified prehospital FBAO patient encounters in Alberta, Canada between Jan 1, 2018 and Dec 31,2021 using the provincial emergency medical services' medical records, deterministically linked to hospital data. Two physicians reviewed encounters to determine cases and extract data. Multivariable logistic regression determined the adjusted odds ratio of FBAO relief (primary outcome) and survival to discharge for the exposure of BLS interventions (abdominal thrusts [AT], chest compressions/thrusts [CC], or combinations) relative to back blows [BB]. Intervention-associated injuries were identified using International Classification of Diseases codes, followed by health records review. RESULTS: We identified 3,677 patient encounters, including 709 FBAOs requiring intervention. Bystanders performed the initial BLS intervention in 488 cases (77.4%). Bystanders and paramedics did not relieve the FBAO in 151 (23.5%) and 11 (16.7%) cases, respectively. FBAOs not relieved before paramedic arrival had a higher proportion of deaths (n = 4[0.4%] versus n = 92[42.4%], p < 0.001). AT and CC were associated with decreased odds of FBAO relief relative to BB (adjusted odds ratio [aOR] 0.49 [95%CI 0.30-0.80] and 0.14 [95%CI 0.07-0.28], respectively). CC were associated with decreased odds of survival to discharge (aOR 0.04 [95%CI 0.01-0.32]). AT, CC, and BB were implicated in intervention-associated injuries in four, nine, and zero cases, respectively. CONCLUSIONS: Back blows are associated with improved outcomes compared to abdominal thrusts and chest compressions. These data can inform prospective studies aimed at improving response to choking emergencies.

Aim: To validate a case definition for foreign body airway obstructions (FBAO) using International Classification of Diseases version 10 (ICD-10) codes to accurately identify patients in administrative health databases and improve reporting on this injury. Methods: We identified prehospital patient encounters in Alberta, Canada between Jan 1, 2018 and Dec 31, 2021 by querying the provincial emergency medical services' (EMS) patient care records for FBAO-related presentations, EMS protocols, or treatments. We deterministically linked EMS patient encounters to data on emergency department visits and hospital admissions, which included ICD-10 codes. Two physicians independently reviewed encounters to determine true FBAO cases. We then calculated diagnostic accuracy measures (sensitivity, specificity, likelihood ratios) of various algorithms. Results: We identified 3677 EMS patient encounters, 2121 were linked to hospital administrative databases. Of these encounters, 825 (38.9%) were true FBAO. The combination of two ICD-10 codes (T17 = foreign body in the respiratory tract or T18.0 = foreign body in the mouth) was the most specific algorithm (96.9% [95%CI 95.8-97.8%]), while the combination of all FBAO-related ICD-10 codes and R06.8 (other breathing abnormalities) was the most sensitive (75.0% [95%CI 71.9-78.0]). We identified an additional 453 (35.4%) FBAO cases not transported by EMS (due to death or transport refusal), and therefore not linked to the hospital administrative databases. Of these unlinked encounters, 44 (9.7%) cases resulted in the patient's death. Conclusions: FBAO can be identified with reasonable accuracy using health administrative data and ICD-10 codes. All algorithms had a trade-off between sensitivity and specificity, and failed to identify a third of FBAO cases, of which 10% resulted in death.
RESUMEN
Aim: To collect, analyze and report the first prospective, industry-independent, data on airway clearance devices as novel foreign body airway obstruction interventions. Methods: We recruited adult airway clearance device users between July 1, 2021 and June 30, 2023 using a centralized website and email follow-up. The data collection tool captured patient, responder, situation, and outcome variables. Multi-step respondent validation occurred using electronic and geolocation verification, a random selection follow-up process, and physician review of all submitted cases. Results: We recruited 186 airway clearance device users (LifeVac©:157 [84.4%]; Dechoker©:29 [15.6%]). LifeVac© was the last intervention before foreign body airway obstruction relief in 151 of 157 cases. Of these, 150 survived to discharge. A basic life support intervention was used before LifeVac© in 119 cases, including the 6 cases where LifeVac© also failed. We identified two adverse events using LifeVac© (perioral bruising), while we could not ascertain whether another 7 were due to the foreign body or LifeVac© (3 = airway edema; 3 = oropharyngeal abrasions; 1 = esophageal perforation). Dechoker© was the last intervention before obstruction relief in 27 of 29 cases and all cases survived. A basic life support intervention was used before Dechoker© in 21 cases, including both where Dechoker© also failed. We identified one adverse event using Dechoker© (oropharyngeal abrasions). Conclusion: Within these cases, airway clearance devices appear to be effective at relieving foreign body airway obstructions. However, this data should be considered preliminary and hypothesis generating due to several limitations. We urge the resuscitation community to proactively evaluate airway clearance devices to ensure the public remains updated with best practices.

Background: Choking is a prevalent source of injury and mortality worldwide. Traditional choking interventions, including abdominal thrusts and back blows, have remained the standard of care for decades despite limited published data. Suction-based airway clearance devices (ACDs) are becoming increasingly popular and there is an urgent need to evaluate their role in choking intervention. The aim of this study was to describe the effectiveness (i.e., resolution of choking symptoms) and safety (i.e., adverse events) of identified airway clearance devices interventions to date. Methods: This retrospective descriptive analysis included any individual who self-identified to manufacturers as having used an ACD as a choking intervention prior to 1 July 2021. Records were included if they contained three clinical variables (patient's age, type of foreign body, and resolution of choking symptoms). Researchers performed data extraction using a standardized form which included patient, situational, and outcome variables. Results: The analysis included 124 non-invasive (LifeVac©) and 61 minimally invasive (Dechoker©) ACD interventions. Median patient age was 40 (LifeVac©, 2−80) and 73 (Dechoker©, 5−84) with extremes of age being most common [<5 years: LifeVac© 37.1%, Dechoker© 23.0%; 80+ years: 27.4%, 37.7%]. Food was the most frequent foreign body (LifeVac© 84.7%, Dechoker© 91.8%). Abdominal thrusts (LifeVac© 37.9%, Dechoker© 31.1%) and back blows (LifeVac© 39.5%, Dechoker© 41.0%) were often co-interventions. Resolution of choking symptoms occurred following use of the ACD in 123 (LifeVac©) and 60 (Dechoker©) cases. Three adverse events (1.6%) were reported: disconnection of bellows/mask during intervention (LifeVac©), a lip laceration (Dechoker©), and an avulsed tooth (Dechoker©). Conclusion: Initial available data has shown ACDs to be promising in the treatment of choking. However, limitations in data collection methods and quality exist. The second phase of this evaluation will be an industry independent, prospective assessment in order to improve data quality, and inform future choking intervention algorithms.

Background Foreign body airway obstructions (FBAOs, choking) are a significant cause of preventable mortality. Abdominal thrusts, back blows, and chest compressions are traditional interventions. However, suction-based airway clearance devices (ACDs) have recently been marketed as an alternative. Of note, there is limited published evidence regarding their efficacy and safety. Our research has two aims: (1) to investigate what situational and patient factors are frequently identified, and which are associated with relief of the FBAO and survival in individuals with FBAOs treated with an ACD; and (2) to describe the experience of individuals who have used ACDs in response to a FBAO and identify facilitators and barriers to the use of ACDs compared to traditional interventions. Methods and analysis A prospective database will be developed using an online reporting system to capture ACD uses, independent of manufacturers, from July 1st, 2021 to December 31st, 2023. Descriptive statistics will be used to summarize cases, outcomes, and adverse events. Clinically important subgroups will be stratified for analysis, including the severity of obstruction, patient demographics, and training of ACD users. Semi-structured interviews will also be conducted with a subset of ACD users to describe in detail their experience using the device. Themes from these interviews will be assessed using the theoretical domains framework. Discussion This study will improve the evidence surrounding ACDs and compare it to current data for traditional techniques, with the aim of optimizing FBAO treatment. Data on ACDs are urgently needed as these devices are already being used by parents, caregivers, lay rescuers, and healthcare professionals to respond to choking emergencies. This evaluation will provide important information about their effectiveness and any safety concerns which can inform the public, resuscitation guidelines, and future research studies.

This protocol outlines the planned methodology for a systematic review and meta-analysis. The primary objective of the review is to identify all-cause readmission rates for individuals hospitalized for an upper GI bleed (UGIB). Secondary objectives will include GI bleed-specific readmission rates, mortality (all-cause and GI bleed-specific), readmission diagnosis, and length of stay on readmission visit. High-risk subgroups will also be explored including age, sex, type of GI bleed (e.g., variceal or not), anti-coagulation status, and comorbidity status. Through this review, the research team aims to describe an important quality indicator, which has implications for both patient safety post-discharge after an UGIB and healthcare resource utilization.
RESUMEN
This study describes the protocol for a systematic review and meta-analysis. The primary objective of the review is to identify experimental studies assessing the effectiveness of interventions that aim to reduce the proportion of computed tomography (CT) in emergency departments (EDs). Data permitting, our secondary objectives will be to assess the impact of reduction in CT utilization on the length of stay, admission to hospital, and uptake/satisfaction with the intervention. When available, balancing measures such as readmission to hospital or ED revisit rates will be included. Pre-defined subgroup analyses include patient populations (adult or pediatric), type of ED, and the nature of the intervention. Through this review, the research team aims to inform knowledge translation initiatives aimed at lowering CT usage in the ED by identifying the most effective interventions to safely improve CT resource stewardship.
RESUMEN
Newfoundland and Labrador (NL) has one of the highest provincial drowning rates in Canada, largely due to the many rural communities located near bodies of water. Factor in the province's cold climate (average NL's freshwater temperature is below 5.4°C)and the prevalence of winter recreational activities among the population, there exists an inherent risk of ice-related injuries and subsequent hypothermia. Oftentimes, these injuries occur in remote/rural settings where immediate support from Emergency Medical Services (EMS) may not be available. During this critical period, it frequently falls on individuals without formal healthcare training to provide lifesaving measures until help arrives. Training individuals in rural communities plays an important role in ensuring public safety. In recent years, simulation-based education has become an essential tool in medical, marine and first aid training. It provides learners with a safe environment to hone their skills and has been shown to be superior to traditional clinical teaching methods. The following case aims to train laypeople from rural settings in the immediate management of an individual who becomes hypothermic following immersion into cold water. However, reaching these individuals to provide training can be a challenge in a province with such a vast geography. To assist with overcoming this, the development of a simulation center that is portable between communities (or Mobile Tele-Simulation Unit) has occurred. By utilizing modern technology, this paper also proposes an innovative method of connecting with learners in more difficult to reach regions.
