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

May 7, 2026

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.

Utilization and Metrics Associated with Paramedic Treat and Discharge Medical Directives for Paramedic Services and Emergency Departments: A Retrospective Cohort Study

May 1, 2026

The authors aimed to evaluate the utilization of prehospital treat and discharge directives by paramedics in Ontario, Canada, and to analyze the associated operational metrics and emergency department (ED) utilization among eligible patients. The study found that while paramedic discharge was infrequently used, it resulted in significantly shorter call durations and reduced subsequent ED visits, suggesting potential benefits for healthcare system efficiency. Further research is needed to assess the safety and broader impact of these directives.

Emergency Medicine Residents in the Prehospital Setting: Does this Augment Training?

May 1, 2026

This study investigates whether the inclusion of a dedicated response vehicle staffed by emergency medicine residents enhances their prehospital training experiences. By analyzing patient care records over five years, the authors quantify the number and types of prehospital encounters, revealing that residents gained significant exposure to critical situations such as cardiac arrests and trauma cases. The findings suggest that this approach effectively augments the educational curriculum for emergency medicine residents.

Comparison of needle decompression to simple (finger) thoracostomy in non-perfused cadaveric models with theoretical tension pneumothorax

Apr 29, 2026

The study aimed to compare the effectiveness of needle decompression versus simple thoracostomy in treating theoretical tension pneumothorax using cadaveric models. Results indicated that simple thoracostomy was more successful (92.1% vs. 76.3%) and faster in relieving the tension pneumothorax compared to needle decompression. The findings suggest that while both methods are viable, simple thoracostomy may be the preferred technique in emergency settings.

Emergency Medical Services Responses at a Large Immigration Detention Facility in Rural Georgia: A Descriptive Analysis

Apr 24, 2026

This study aims to analyze the impact of Emergency Medical Services (EMS) activations originating from the Stewart Detention Center (SDC) in Georgia, particularly in the context of increasing detainee populations. The authors found that SDC accounted for a significant portion of local EMS responses, with many cases requiring transport for serious medical conditions, highlighting the operational challenges faced by EMS in rural areas. The findings suggest a need for further research on the implications of these medical emergencies for EMS systems and public health infrastructure.

The Estimated Benefit of Lights and Sirens During Ambulance Transport

Apr 20, 2026

The authors aimed to estimate the effect of using lights and sirens on ambulance trip duration and pace, addressing concerns about the associated risks of increased collisions. Through an analysis of 25,902 incidents, they found that lights and sirens were linked to a median time savings of approximately 3.0 to 3.3 minutes per trip and a faster pace of 0.3 min/km. The study highlights the need for further investigation into the conditions under which the benefits of using lights and sirens outweigh the risks of emergency driving.

Intranasal Versus Intramuscular Midazolam in Pediatric Seizure Control: A Systematic Review and Meta-Analysis

Apr 17, 2026

The authors aimed to determine whether intranasal (IN) or intramuscular (IM) administration of midazolam is more effective for rapid seizure control in pediatric patients, particularly in prehospital settings where intravenous access is not available. Their meta-analysis of five studies involving 3,933 patients found that IM midazolam resulted in quicker seizure termination and a lower need for rescue therapy compared to IN midazolam. Consequently, IM midazolam is suggested as a preferable first-line treatment for acute seizures in these scenarios.

Out-of-Hospital Management of Suspected Spinal Cord Injuries: How Much Evidence Does it Take to Change Practice?

Apr 14, 2026

The authors examine the ongoing debate regarding the practice of spinal immobilization in out-of-hospital management of suspected spinal cord injuries, questioning how much evidence is required to change established medical practices. They highlight the extensive multidisciplinary efforts and accumulated research over the past 25 years that consistently indicate spinal immobilization is harmful and lacks demonstrable benefits. The central inquiry is how many more studies and professional consensus are necessary before this practice is abandoned in favor of safer alternatives.

Performance of Machine Learning Models for Sepsis and Stroke Detection Using EMS Data

Apr 13, 2026

The authors aimed to evaluate the feasibility and performance of machine learning models for early detection of sepsis and stroke using emergency medical services (EMS) electronic health record data. Their study found that while the models demonstrated reasonable sensitivity and specificity, particularly when applying a majority prediction approach, incorporating free-text narratives improved sensitivity at the cost of specificity. The findings suggest that machine learning could enhance prehospital identification of these conditions, with future research needed to refine models using EMS-specific data.

Paramedics' decisions to withhold resuscitation in traumatic cardiac arrest: accuracy of paramedic assessments compared with autopsy findings

Apr 8, 2026

This study investigates the accuracy of paramedics' decisions to withhold cardiopulmonary resuscitation (CPR) in cases of traumatic cardiac arrest (TCA) by comparing their assessments with autopsy findings. The findings indicate that paramedics accurately identify injuries incompatible with life in the majority of cases, and when such injuries are not present, they consider additional factors such as time to EMS contact and injury severity before making their decision. Overall, the research highlights the high specificity of paramedic assessments in determining the appropriateness of resuscitation efforts in prehospital settings.
