Patient and mission characteristics of helicopter emergency medical services in the Republic of Ireland: a retrospective analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe National Ambulance Service (NAS) has operated a Paramedic-staffed Helicopter Emergency Medical Services (HEMS) in the Republic of Ireland since 2012. This study describes patient and mission characteristics, to provide insight into this service and inform future service development.
methodsA nationwide population-based retrospective study of HEMS missions was conducted from routinely collected health data over an 11- year period between 1 July 2012 and 30 June 2023.
resultsIn the study period HEMS in Ireland received 8,392 mission requests, Patient contact occurred in 60.1% of missions (n = 5,045) and 73.4% (n = 3703) were airlifted to hospital. Adults represented 90.3% (n = 4,535) of patients, predominantly male at 69.1%, with a median age of 55 years (IQR: 34 years) [35:69]. Medical patients accounted for 50.3% (n = 2,524), cardiac aetiologies (32.3%) and out of hospital cardiac arrest (OHCA) (30.3%) were the most common medical presentation. Trauma patients account for 49.7% (n = 2,498). Road Traffic Collisions (RTCs) (31.4%) followed by farming and machinery incidents (17.4%) were the most common trauma presentation. HEMS teams significantly reduced pain in both trauma (ꭕ
conclusionsOver the past decade, HEMS in Ireland has provided a valuable contribution to the care of seriously ill and injured patients, particularly in the west and southwest. Service use reflects HEMS base proximity, indicating potential benefits from geographic expansion. Current activation criteria appears to target an appropriate patient cohort, however sustained reassessment of dispatch criteria and hours of operation may enhance service availability. Continued development should focus on adopting evidence based-practices and advancing critical care capacity to align with international HEMS standards.
