Blood transfusions have been the cornerstone of life support since the introduction of the ABO classification in the 20th century. The physiologic goal is to restore adequate tissue oxygenation when the demand exceeds the offer. Although it can be a life-saving therapy, blood transfusions can lead to serious adverse effects, and it is essential that physicians remain up to date with the current literature and are aware of the pathophysiology, initial management and risks of each type of transfusion reaction. We aim to provide a structured overview of the pathophysiology, clinical presentation, diagnostic approach and management of acute transfusion reactions based on the literature available in 2022. The numbers of blood transfusions, transfusion reactions and the reporting rate of transfusion reactions differ between countries in Europe. The most frequent transfusion reactions in 2020 were alloimmunizations, febrile non-hemolytic transfusion reactions and allergic transfusion reactions. Transfusion-related acute lung injury, transfusion-associated circulatory overload and septic transfusion reactions were less frequent. Furthermore, the COVID-19 pandemic has challenged the healthcare system with decreasing blood donations and blood supplies, as well as rising concerns within the medical community but also in patients about blood safety and transfusion reactions in COVID-19 patients. The best way to prevent transfusion reactions is to avoid unnecessary blood transfusions and maintain a transfusion-restrictive strategy. Any symptom occurring within 24 h of a blood transfusion should be considered a transfusion reaction and referred to the hemovigilance reporting system. The initial management of blood transfusion reactions requires early identification, immediate interruption of the transfusion, early consultation of the hematologic and ICU departments and fluid resuscitation.

Background: Stroke treatment has significantly improved over the last decades, but the complexity of stroke cases requires specialized care through dedicated teams with specific knowledge and training. The National Institutes of Health Stroke Scale (NIHSS), widely used to assess neurological deficits and make treatment decisions, is reliable but requires specific training and certification. The traditional didactic training method, based on a video, may not adequately address certain NIHSS intricacies nor engage health care professionals (HCPs) in continuous learning, leading to suboptimal proficiency. In the context of time-constrained clinical settings, highly interactive e-learning could be a promising alternative for NIHSS knowledge acquisition and retention. Objective: This study aimed to assess the efficacy of a highly interactive e-learning module compared with a traditional didactic video in improving NIHSS knowledge among previously trained HCPs. Furthermore, its impact on knowledge retention was also assessed. Methods: A prospective, multicentric, triple-blind, and web-based randomized controlled trial was conducted in 3 Swiss university hospitals, involving HCPs previously trained in NIHSS. Invitations were sent through email, and participants were randomized to either the e-learning or traditional didactic video group through a fully automated process upon self-registration on the website. A 50-question quiz was administered before and after exposure to the training method, and scores were compared to assess knowledge acquisition. The quiz was repeated after 1 month to evaluate retention. Subjective assessments of learning methods that is, user satisfaction, probability of recommendation, perceived difficulty, and perception of duration, were also collected through a Likert-scale questionnaire. A sample size of 72 participants were deemed necessary to have an 80% chance of detecting a difference of 2 points in the postcourse quiz between groups at the 5% significance level. Results: Invitations to participate were sent through email to an estimated 325 HCPs. 174 HCPs enrolled in the study, of which 97 completed the study course. Both learning methods significantly improved NIHSS knowledge, with an improvement of 3.2 (range 2.0-4.3) points in the e-learning group and of 2.1 (1.2-3.1) points in the video group. However, the e-learning group performed better, with higher scores in knowledge acquisition (median score 39.0, IQR 36.0-41.0 vs 37, IQR 34.0-39.0; P=.03) and in knowledge retention (mean score 38.2, 95% CI 36.7-39.7 vs 35.8, 95% CI 34.8-36.8; P=.007). Participants in the e-learning group were more likely to recommend the learning method (77% vs 49%, P=.02), while no significant difference was found for satisfaction (P=.17), perceived duration (P=.17), and difficulty (P=.32). Conclusions: A highly interactive e-learning module was found to be an effective asynchronous method for NIHSS knowledge acquisition and retention in previously NIHSS-trained HCPs, and may now be considered for inclusion in NIHSS training programs for HCPs.

Super-absorbent polymers (SAPs) possess the ability to absorb large amounts of water and are widely used in medical settings. Commonly used in vomit bags to contain fluids, reduce spillage, and enhance bedside hygiene, SAPs are generally regarded as safe and non-toxic. However, we report a tragic incident where the accidental ingestion of SAPs led to fatal asphyxiation, highlighting a critical safety concern. A 76-year-old female suffering from advanced Alzheimer’s dementia was brought to the emergency department following a fall with cervical trauma. Following a complaint of nausea, she was given a vomit bag containing a sachet of approximately 9 g of SAP. Thirty minutes later, she was found deceased in the waiting area, with a grayish, half-hardened gel blocking her oropharynx and remnants of a chewed SAP sachet. Pathological analysis confirmed death by asphyxiation caused by the SAP expanding in her oropharynx upon contact with saliva. This case emphasizes the potential dangers of SAPs when accidentally ingested and it is imperative that such products are kept out of reach of vulnerable populations. In cases of airway obstruction, there are no specific treatments available. Laryngoscopy may be impossible, necessitating the prompt consideration of an emergency tracheotomy. Experimental data suggest the use of an aerosol of warm alkaline hydrogen peroxide solution to dissolve these obstructive foreign bodies, but further studies are needed to validate its use in emergency situations.

This paper describes how the profession of paramedics has evolved in Switzerland and takes the perspective of public health. Ambulance drivers play an important role in the health system, not only as a response to emergencies, but also by working in an interprofessional and interdisciplinary manner in response to other public health needs, such as home care, triage, telemedicine and interhospital transfers. This pre-hospital system is rapidly evolving and relies on the work of paramedics.

Background Overcrowding in the emergency department (ED) is a global problem and a source of morbidity and mortality and exhaustion for the teams. Despite multiple strategies proposed to overcome overcrowding, the accumulation of patients lying in bed awaiting treatment or hospitalisation is often inevitable and a major obstacle to quality of care. We initiated a quality improvement project with the objective of zero patients lying in bed awaiting care/referral outside a care area. Methods Several plan–do–study–act (PDSA) cycles were tested and implemented to achieve and especially maintain the goal of having zero patients waiting for care outside the ED care area. The project team introduced and adapted five rules during these cycles: (1) no patients lying down outside of a care unit; (2) forward movement; (3) examination room always available; (4) team huddle and (5) an organisation overcrowding plan. Results Adaptation of ED organisation in the form of PDSA cycles allowed to obtain a collective team dimension to patient flow management. Since December 2021, despite an increase in activity, no patient is placed in a lying-in waiting area outside a care zone, irrespective of their care level. Vital distress and fragile patients who need to be kept in a supine position are treated immediately. In 2022, waiting time before medical contact was <2 hours for 90% of all patients combined. Conclusions The PDSA strategy based on these five measures allowed to remove in-house obstacles to the internal flow of patients and to fight against their installation outside the care area. These measures are easily replicable by other management teams. Quality indicators of EDs are often heterogeneous, but we propose that the absence of patients lying on a stretcher outside a care area could be part of these indicators, and thus contribute to the improvement and safety of care provided to all patients.
