Factors Influencing Outcomes of Trauma Patients Transferred in Trauma Systems by Air or Ground Ambulance: A Systematic Review.
Prehosp Emerg Care
January 2025
School of Health Sciences, University of East Anglia, Norfolk, UK.
Objectives: This systematic review aims to determine the effectiveness of ambulance transportation versus helicopter transportation on mortality for trauma patients.
Methods: A systematic review of published and unpublished databases (to August 2023) was performed. Studies, reporting mortality, for people who experienced trauma and were transported to a trauma unit by ambulance or helicopter were eligible.
Impact of short-term aircraft noise on cardiovascular disease risk in the area surrounding London Heathrow airport: the RISTANCO epidemiological study.
Public Health Res (Southampt)
December 2024
Centre for Environmental Health and Sustainability, University of Leicester, Leicester, UK.
Background: Long-term exposure to aircraft noise has been associated with small increases in cardiovascular disease risk, but there are almost no short-term exposure studies.
Objectives: Research questions were: Is there an association between short-term changes in exposure to aircraft noise and cardiovascular morbidity and mortality? What are the key effect modifiers? Is there variability in risk estimates between areas with consistent versus changing patterns of noise exposure? Do risk estimates differ when using different noise metrics?
Design: Descriptive analyses of noise levels and variability at different times of day, analyses of inequalities in noise exposure and case-crossover analyses of cardiovascular events in relation to aircraft noise exposure.
Setting: Area surrounding London Heathrow airport.
Determining What Proportion of Helicopter Emergency Medical Services-Transported Patients Are Urban Versus Rurally Based: A Retrospective 36-Year Geospatial Analysis of a Critical Care Helicopter Emergency Medical Services Organization's Patient Transports.

Article Synopsis
- The study investigates the role of Helicopter Emergency Medical Services (HEMS) in reducing mortality rates for patients in rural areas and assesses its impact on urban residents who are transferred by helicopter while in rural settings.
- A retrospective analysis of HEMS data from 1985 to 2022 revealed that about 10.76% of cases involved patients residing in urban areas near HEMS bases, with the majority (89.24%) coming from non-urban locations.
- The findings indicate that HEMS not only benefits rural residents but also serves urban individuals who may travel to or through rural regions, highlighting the broad impact of these services across various communities.

Shock
January 2025
Department of Anesthesiology, University of Maryland School of Medicine, Baltimore, Maryland.
Article Synopsis
- The study focuses on assessing how well continuous vital signs (VS) can predict the severity of traumatic injuries and the need for lifesaving interventions (LSIs) compared to traditional invasive methods like lactate measurements.
- Researchers analyzed data from 300 patients treated in a prehospital helicopter setting, using continuous VS along with laboratory tests to see which method was better at predicting outcomes such as ICU admission and discharge times.
- The findings indicated that continuous VS models outperformed single initial VS readings for predicting LSIs and ICU stay length and showed performance comparable to lactate tests for predicting 24-hour discharge, highlighting their potential in emergency medical decision-making.
