Evaluation of a team-based approach for emergency department patients with time critical intracranial conditions.
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. An erratum has been issued. 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
introductionMany time-critical neurosurgical brain conditions do not meet traditional ED major trauma or stroke team activation criteria and thus do not benefit from the associated expedited imaging and specialist review. To address this, a "Critical Head" protocol was developed. The aim was to determine the effect of this on time to CT scan, neurosurgical intervention (if indicated) and specialist team review.
methodQuasi-experimental study, involving retrospective analyses of data of all potential Critical Head patients presenting to Wollongong ED from 1 January 2018 to 26 May 2023, with the protocol go-live on 7 March 2023. Descriptive statistics and study outcomes were compared before and after protocol implementation. R Studio 2024 was used for analyses and alpha was set to 0.05.
resultsTwo hundred and two patients were included (123 control/pre-intervention, 119 intervention). There was no significant difference in age, sex or presence of intracranial conditions between groups. Median time from triage to CT decreased in the intervention group by 15% (7 min, 47[33,95] to 40[25,66], P = 0.020). There was a 33% (67 min) reduction to surgery start time in the intervention (204[621752] to 137[108247] min, P = 0.042) (urgent neurosurgery). Reductions in time to specialist team reviews were observed in ICU (n = 86, 132[58192] to 42[6103] min, P < 0.001) and neurosurgery (n = 158, 104[69 202] to 44[16111] min, P < 0.001). ICU and hospital length of stay did not differ significantly, nor did Glasgow Coma Outcome Scale score at discharge.
conclusionThe Critical Head protocol for patients with time-critical intracranial conditions reduced time to CT scan, operative intervention and specialist team review.
