Pre-hospital mortality among pediatric trauma patients in Nova Scotia.
Article in CJEM, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesLimited data exist on pre-hospital pediatric trauma mortality in Canada. The Nova Scotia Trauma Registry is a provincial population-based registry that captures data from the Medical Examiner Service. This study examined the characteristics of pediatric trauma patient mortality in the pre-hospital and in-hospital settings.
methodsWe conducted a cohort study of major pediatric traumas recorded in our provincial database from April 1, 2001 to March 31, 2018. Characteristics of pre-hospital and in-hospital deaths were compared with t tests and Chi-square analyses. Multivariate regression modeling was used to identify predictors of pre-hospital mortality. The geographic distribution of pre-hospital trauma was assessed using choropleth maps.
resultsWe identified 1,258 pediatric traumas, resulting in 217 deaths (137 pre-hospital, 80 in-hospital). Males accounted for 62.7% of fatalities. The 15-17 age group accounted for most deaths in both groups (pre-hospital 61.3%; in-hospital 41.3%). Injuries sustained in rural areas resulted in 74.7% of all deaths. For both groups, blunt trauma was the predominant injury type and motor vehicle collisions, the most prevalent injury mechanism. Patients who died pre-hospital had a higher mean age (13.3 vs. 10.7, p = 0.002) and a greater proportion were intentional injuries (23.4% vs. 15%; p = 0.02). Urban residency was more frequently observed in in-hospital deaths (57.5% vs. 36.5%, p < 0.001). Pre-hospital mortality was associated with increasing age (OR 1.1), higher injury severity score (OR 1.1), and intentional injury (OR 15.6).
conclusionOver 10% of major pediatric traumas resulted in pre-hospital death, primarily from motor vehicle collisions in rural areas. Compared to in-hospital mortality, patients who died pre-hospital were older with more severe injuries and more likely to have intentionally injured themselves. These results underscore the importance for emergency physicians and EMS systems to consider geographic factors and injury patterns, advocate for improved injury prevention programs, mental health supports, and delivery of on-scene critical care services.
