Prevalence of clinical deterioration in the pre-hospital setting.
Article in Emergency medicine Australasia : EMA, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveImproved understanding of the deteriorating patient in the pre-hospital setting may result in earlier recognition and response. Considering the effects of undetected deterioration are profound, it is fundamental to report the prevalence of pre-hospital clinical deterioration to advance our understanding. The present study investigated the prevalence of pre-hospital clinical deterioration and adverse events (AEs) within 3 days of the pre-hospital episode of care.
methodsThis retrospective cohort study was based on pre-hospital incidents involving adult patients attended by Queensland Ambulance Service between 1 January 2018 and 31 December 2020. Due to lacking a standardised definition of pre-hospital clinical deterioration, established early warning scores (NEWS, MEWS and Q-ADDS) were calculated from pre-hospital vital signs to identify clinical deterioration. Linked hospital data were used to identify the occurrence of an AE.
resultsSome degree of physiological derangement was initially observed in over half of the patients, and pre-hospital clinical deterioration was seen in 2.7%-4% of patients. The prevalence of AEs was 3.2%. Patients that experienced an AE were more likely to be male, elderly, suffering from a medical (non-trauma) condition, and had a greater burden of disease. Concerningly, almost 50% of patients that suffered an AE did not meet escalation thresholds of NEWS, MEWS or Q-ADDS.
conclusionsThe present study found the prevalence of pre-hospital clinical deterioration and AEs subsequent to pre-hospital episodes of care to be low. Future research should prioritise using standardised criteria to define pre-hospital clinical deterioration and evaluate the performance of early warning scores.
