The Ability of First Aid Providers to Recognize Anaphylaxis: A Scoping Review.

Early recognition of anaphylaxis is critical to early treatment and often occurs in the first aid setting. However, the ability of first aid providers to recognize anaphylaxis is unknown. We sought to examine the evidence regarding first aid providers' ability to recognize anaphylaxis. Our scoping review was performed as part of the International Liaison Committee on Resuscitation (ILCOR) continuous evidence evaluation processes to update the 2020 ILCOR Consensus on Science with Treatment Recommendations. We searched Medline, Embase, Cochrane, and the gray literature from 2010 to September 2022. The population included adults and children experiencing anaphylaxis with a description of any specific symptom to a first aid provider. Recognition of anaphylaxis was the primary outcome. Two investigators (DM and PC) reviewed abstracts and extracted and assessed the data. Discrepancies between the reviewers were resolved by discussion and consensus with the ILCOR First Aid Task Force. Out of 957 hits, 17 studies met inclusion criteria: one review and meta-analysis, two experimental studies, and 14 observational studies. We did not identify any studies that directly addressed our PICOST (Population, Intervention, Control, Outcomes, Study Design, and Timeframe) as none were performed in the first aid setting. Articles included individuals who may be first aid providers as patients and parents (n=5), teachers, students or school staff (n=8), caregivers and patients (n= 2) or nannies (n=1). All included studies were conducted in high-income countries. Our scoping review found that signs and symptoms of anaphylaxis were not specific and did not allow for easy identification by the first aid provider. Studies focused on education (n=10) and protocols (n=2) and found that both could have a positive impact on anaphylaxis recognition and management. While we did not identify any clinical studies that directly addressed the ability of first aid providers to identify anaphylaxis, future studies examining education methods and action plans may help improve the identification of anaphylaxis by first aid providers.

Stroke Recognition for First Aid Providers: A Systematic Review and Meta-Analysis.

Aim To perform a systematic review of the literature on the effectiveness of existing stroke recognition scales used in a prehospital setting and suitable for use by first aid providers. The systematic review will be used to inform an update of international first aid guidelines. Methods We followed the Cochrane Handbook for Systematic Reviews of Interventions methodology and report results according to PRISMA guidelines. We searched Medline, Embase and CENTRAL on May 25, 2020 for studies of stroke recognition scales used by first aid providers, paramedics and nurses for adults with suspected acute stroke in a prehospital setting. Outcomes included change in time to treatment, initial recognition of stroke, survival and discharge with favorable neurologic status, and increased layperson recognition of the signs of stroke. Two investigators reviewed abstracts, extracted and assessed the data for risk of bias. The certainty of evidence was evaluated using GRADE methodology. Results We included 24 observational studies with 10,446 patients evaluating 10 stroke scales (SS). All evidence was of moderate to very low certainty. Use of the Kurashiki Prehospital SS (KPSS), Ontario Prehospital SS (OPSS) and Face Arm Speech Time SS (FAST) was associated with an increased number of suspected stroke patients arriving to a hospital within three hours and, for OPSS, a higher rate of thrombolytic therapy. The KPSS was associated with a decreased time from symptom onset to hospital arrival. Use of FAST Emergency Response (FASTER) was associated with decreased time from door to tomography and from symptom onset to treatment. The Los Angeles Prehospital Stroke Scale (LAPSS) was associated with an increased number of correct initial diagnoses. Meta-analysis found the summary estimate sensitivity of four scales ranged from 0.78 to 0.86. The FAST and Cincinnati Prehospital Stroke Scale (CPSS) were found to have a summary estimated sensitivity of 0.86, 95% CI [0.69-0.94] and 0.81, 95% CI [0.70-0.89], respectively. Conclusion Stroke recognition scales used in the prehospital first aid setting improves the recognition and diagnosis of stroke, thereby aiding the emergency services to triage stroke victims directly down an appropriate stroke care pathway. Of those prehospital scales evaluated by more than a single study, FAST and Melbourne Ambulance Stroke Screen (MASS) were found to be the most sensitive for stroke recognition, while the CPSS had higher specificity. When blood glucose cannot be measured, the simplicity of FAST and CPSS makes these particular stroke scales appropriate for non-medical first aid providers.

Up to 206 Million People Reached and Over 5.4 Million Trained in Cardiopulmonary Resuscitation Worldwide: The 2019 International Liaison Committee on Resuscitation World Restart a Heart Initiative.

Sudden out-of-hospital cardiac arrest is the third leading cause of death in industrialized nations. Many of these lives could be saved if bystander cardiopulmonary resuscitation rates were better. "All citizens of the world can save a life-CHECK-CALL-COMPRESS." With these words, the International Liaison Committee on Resuscitation launched the 2019 global "World Restart a Heart" initiative to increase public awareness and improve the rates of bystander cardiopulmonary resuscitation and overall survival for millions of victims of cardiac arrest globally. All participating organizations were asked to train and to report the numbers of people trained and reached. Overall, social media impact and awareness reached up to 206 million people, and >5.4 million people were trained in cardiopulmonary resuscitation worldwide in 2019. Tool kits and information packs were circulated to 194 countries worldwide. Our simple and unified global message, "CHECK-CALL-COMPRESS," will save hundreds of thousands of lives worldwide and will further enable many policy makers around the world to take immediate and sustainable action in this most important healthcare issue and initiative.

Immediate Interventions for Presyncope of Vasovagal or Orthostatic Origin: A Systematic Review.

Background: Syncope is a common condition that may be prevented. There are non-pharmacological interventions that may be of benefit during the acute episode preceding syncope (presyncope), including physical counter-pressure maneuvers (PCM) or change of body position. We performed a systematic review of interventions that may be applied during presyncope as an immediate, first aid tactic. Methods: We searched Medline, Embase, and CINAHL and used the Grading of Recommendations Assessment, Development and Evaluation methods, and risk of bias assessments to determine the certainty of the evidence. We included randomized controlled trials (RCTs), non-randomized studies, and case series investigating adults and children with signs and symptoms of presyncope of suspected vasovagal or orthostatic origin who applied any intervention that could be used as an immediate, first aid intervention. We examined the following outcomes: prevention of syncope, adverse events, symptom improvement, and vital signs. We conducted a sub-group analysis based on the etiology of vasovagal or orthostatic presyncope. Results: We screened 5,160 titles and abstracts followed by 81 full text articles. We identified 8 studies meeting inclusion criteria, including 2 RCTs and 6 observational studies. All studies used PCM in adults and all were judged to be of low and very low certainty of evidence. For prevention of syncope, one RCT demonstrated benefit with the use of PCM (RR = 1.80 [1.26-1.89]), while observational studies failed to show benefit (RR = 1.31 [0.98 - 1.75]). Two RCTs showed benefit in symptom improvement (RR = 6.00 [2.21 - 8.61] and (RR = 1.57 [1.06 - 1.93]). Blood pressure (BP) improved with the use of PCM: systolic BP mean difference (MD) 21 mmHg higher (95% CI: 18.25 to 23.41 BPM) and diastolic BP MD 11 mmHg higher (95% CI: 9.39 to 13.10 mmHg higher). No adverse events were reported. Conclusion: While there is a minimal amount of evidence available and the findings were mixed, PCM may provide benefit for prevention of syncope during acute episodes of presyncope and may be tried in the first aid setting. No evidence was found for other non-pharmacologic interventions or for the use of PCM in children.

Automated external defibrillator use in out-of-hospital cardiac arrest: Current limitations and solutions.

Out-of-hospital sudden cardiac arrest (OHCA) is a major public health issue, with a survival rate at hospital discharge that remains below 10% in most cities, despite huge investments in this domain. Early basic life support (BLS) and early defibrillation using automated external defibrillators (AEDs) stand as key elements for improving OHCA survival rate. Nevertheless, the use of AEDs in OHCA remains low, for a variety of reasons, including the number, accessibility and ease of locating AEDs, as well as bystanders' awareness of BLS manœuvres and of the need to use AEDs. Several measures have been proposed to improve the rate of AED use, including optimization of AED deployment strategies as well as the use of drones to bring the AEDs to the OHCA scene and of mobile applications to locate the nearest AED. If they are to be effective, these measures should be combined with large communication campaigns on OHCA, and wide-scale education of the public in BLS and AEDs, to reduce the burden of OHCA.

[European Guidelines on cardiac arrest, what's new?] / Les recommandations européennes sur l'arrêt cardiaque, quoi de neuf ?

The European recommendations on cardiac arrest are based on the evidence gathered and reviewed by the International Resuscitation Liaison Committee (ILCOR) and were published in October 2015. These recommendations without representing a revolution, constitute an evolution centered on a primary goal to increase survival following cardiac arrest. This improvement in survival depends on four main factors: early identification of cardiac arrest, early access to rescue, early and quality CPR, and access to early defibrillation. These recommendations underline the importance of the interactions between the actors involved in the management of cardiac arrest: medical emergency dispatching personnel, the first provider who administers the CPR and the actors responsible for the deployment of public access defibrillation.
