Clinical Features, CT Imaging Decisions and Yield by Age in Adults With Abdominal Pain in the Emergency Department

The study aimed to evaluate how age influences clinical features, CT imaging decisions, and diagnostic yield in adults presenting with abdominal pain in the emergency department. The findings revealed that CT utilization and diagnostic yield increased with age, while key physical exam findings, such as abdominal tenderness, were less sensitive in older adults. This suggests a need for age-aware imaging strategies and highlights the importance of recognizing abdominal pain as a geriatric-specific concern.

Etiology-specific predictors for short-term functional outcomes of OHCA: A Japanese Nationwide registry study

This study aimed to identify etiology-specific predictors of favorable functional outcomes after out-of-hospital cardiac arrest (OHCA) using data from a nationwide Japanese registry. The results indicated that early defibrillation was a strong predictor of favorable outcomes in cardiac-origin OHCA, while cerebrovascular-origin OHCA outcomes appeared to be more influenced by the initial severity of cerebral injury rather than resuscitation timing. The authors suggest that further prospective studies are needed to validate these findings due to the limitations of their registry-based research.

Regional School-Based CPR Training With Low-Cost Manikin Delivered by School Nurses: The Home "Multiplier" Effect

The authors aimed to evaluate the feasibility and community impact of a nurse-led school CPR program utilizing low-cost manikins, as well as to measure the effectiveness of students teaching CPR to family members at home. The study found that 45.1% of trained students successfully taught CPR to an average of 2.41 family members each, with overall performance scores indicating adequate skills in basic life support but weaker performance in automated external defibrillator use. This suggests that the program effectively extended CPR training beyond the classroom into the community.

Management of patients with suspected but unidentified poisoning in the emergency department: a joint Royal College of Emergency Medicine and National Poisons Information Service best practice guideline

The authors aim to address the challenges in managing patients with suspected but unidentified poisoning in the emergency department by providing a best practice guideline. This guideline outlines a generalized clinical approach for initial assessment, identification of potential toxic agents, and emergency management, utilizing a toxidromic framework while emphasizing the importance of toxicokinetics. It is intended to complement existing poison-specific resources rather than replace them.

Triage administration of sucrose for gastroenteritis in children; a randomized controlled trial

The authors aimed to determine whether administering a concentrated sucrose solution improves oral rehydration intake in children aged 6 months to 7 years presenting with gastroenteritis in the emergency department. Their randomized controlled trial found no significant difference in the volume of rehydration solution ingested or in secondary outcomes such as vomiting episodes and intravenous rehydration between the sucrose and placebo groups. Consequently, the study concludes that a single dose of sucrose solution does not enhance oral rehydration in this patient population.

Lock and Protect, Reducing Access to Adolescent Means of Suicide: A Pilot Feasibility Study

The authors aimed to assess the feasibility and acceptability of "Lock and Protect," a web-based lethal means counseling decision aid for caregivers of adolescents presenting to the emergency department with suicidal thoughts or behaviors. The pilot study found high enrollment and completion rates among caregivers, who reported the tool as respectful, useful, and effective in promoting safer home storage of medications. Overall, the study suggests that "Lock and Protect" is a viable intervention for enhancing suicide prevention efforts in pediatric emergency settings.

On the optimal sodium correction rate in hyponatraemia and clinical outcome: a meta-analysis

The authors aimed to determine the optimal sodium correction rate in hyponatraemia and its impact on clinical outcomes, particularly mortality and the incidence of osmotic demyelination syndrome (ODS). Their meta-analysis of 11 studies involving 27,672 cases found that rapid sodium correction (at thresholds of 8, 10, and 12 mmol/L/24 hours) was associated with significantly lower mortality rates, although it also correlated with a higher incidence of ODS. The findings suggest that while a more liberal approach to sodium correction may improve survival, the risk of ODS, albeit rare, remains a concern.

Extended-Release Buprenorphine Administration by Emergency Medical Services Paramedics: A Case Series

This case series investigates the feasibility of Emergency Medical Services (EMS) administering extended-release buprenorphine (XR-BUP) to individuals with opioid use disorder (OUD) in a 911-based system. The authors aim to determine whether this approach can effectively initiate and maintain medication for opioid use disorder among high-risk populations who face barriers to traditional treatment access. Results indicate successful administration of XR-BUP without adverse effects, leading to improved patient engagement in addiction care, suggesting that EMS may play a crucial role in enhancing treatment access and adherence.

A randomised controlled trial of defibrillation with manual pressure augmentation during out-of-hospital cardiac arrest

The authors aimed to determine whether defibrillation with manual pressure augmentation (MPA) could reduce transthoracic impedance and improve survival rates in patients experiencing out-of-hospital cardiac arrest (OHCA) with a shockable rhythm, compared to standard defibrillation. The study found that while MPA significantly reduced transthoracic impedance, it did not lead to improved survival or other clinical outcomes. The trial was prematurely terminated, and compliance with the MPA intervention was low.

Can a Large Language Model Grounded in Text-Based Agency-Specific Prehospital Protocols Provide Accurate Care Recommendations?

The authors aimed to evaluate the accuracy of a retrieval-augmented generation (RAG)-based large language model (LLM) in providing care recommendations for prehospital emergency scenarios based on specific emergency medical services (EMS) protocols. The study found that the LLM achieved a 75% accuracy rate in recommending appropriate patient care actions across various clinical scenarios, with some notable missed actions, particularly in pediatric cases. Overall, the findings suggest that while the LLM can generate grounded responses, there are areas for improvement in its clinical accuracy.
