A limited number of studies have investigated the association between short-term exposure to PM components and morbidity. The present case-crossover study explored the association between exposure to total PM and its components and emergency ambulance dispatches, which is one of the indicators of morbidity, in the 23 Tokyo wards. Between 2016 and 2018 (mean mass concentrations of total PM 13.5 μg/m), we obtained data, from the Tokyo Fire Department, on the daily cases of ambulance dispatches. Fine particles were collected at a fixed monitoring site and were analyzed to estimate the daily mean concentrations of carbons and ions. We analyzed 1038301 cases of health-based all-cause ambulance dispatches by using a conditional logistic regression model. The average concentrations of total PM over one and the previous day were positively associated with the number of ambulance dispatches. In terms of PM components, the percentage increase per interquartile range (IQR) increase was 0.8% for elemental carbon (IQR = 0.8 μg/m; 95% CI = 0.3-1.3%), 0.9% for sulfate (2.1 μg/m; 0.5-1.4%), and 1.1% for ammonium (1.3 μg/m; 0.4-1.8%) in the PM-adjusted models. This is the first study to find an association between some specific components in PM and ambulance dispatches.

Improving preparedness for time critical prehospital care: a descriptive study of the first responder system in Central Norway.
Scand J Trauma Resusc Emerg Med
January 2025
Department of Emergency Medicine and Pre-Hospital Services, St. Olav's University Hospital, Trondheim, Norway.
Background: First responders exist in several countries and have been a prehospital emergency medical resource in Norwegian municipalities since 2010. However, the Norwegian system has not yet been studied. The aim of this study was to describe the first responder system in Central Norway and how it is used as a supplement to emergency medical services (EMS).

The optimization in the ambulance dispatching process is significant for patients who need early treatments. However, the problem of dynamic ambulance redeployment for destination hospital selection has rarely been investigated. The paper proposes an approach to model and simulate the ambulance dispatching process in multi-agent healthcare environments of large cities.

Background: Timely emergency medical services (EMS) are particularly important among trauma patients, as inefficient EMS systems can result in potentially avoidable death before reaching a hospital. The Dhulikhel Hospital Dispatch Center coordinates and monitors a growing network of ambulances, including seven Type B ambulances staffed with a trained prehospital care provider and medical equipment. This study evaluates the prehospital care and outcomes of trauma patients transported by Type B ambulances to Dhulikhel Hospital's Emergency Department, as monitored by the Dispatch Center.

Warwick Clinical Trials Unit, Warwick Medical School, University of Warwick, Coventry, UK.
Aim: To assess the clinical outcomes of patients with out-of-hospital cardiac arrest attended by prehospital critical care teams compared to non-critical care teams.
Methods: This review was prospectively registered with PROSPERO and the eligibility criteria followed a PICOST framework for ILCOR systematic reviews. Prehospital critical care was defined as any provider with enhanced clinical competencies beyond standard advanced life support algorithms and dedicated dispatch to critically ill patients.
Could video assisted CPR improve treatment in complex cardiac arrest situations? - A case report.

Article Synopsis
- Immediate recognition and prompt action during cardiac arrest, such as CPR and defibrillation, are crucial for survival, but the quality of CPR by bystanders can vary significantly.
- Video-assisted CPR (V-CPR) was introduced in Norway to enhance the effectiveness of dispatchers’ guidance, thereby improving CPR quality performed by laypersons.
- In a specific case involving a 58-year-old man with a cardiac arrest, two untrained bystanders received vital assistance via V-CPR, demonstrating its importance in managing complex situations and enabling high-quality CPR without the need for rescue breaths before emergency medical services arrived.
