Trauma referral audit impact assessment on the outcomes of injured patients via an interrupted time-series analysis: an 11-year before-and-after study of trauma cases at the Maharaj Nakorn Chiang Mai hospital, Thailand.
Article in BMC emergency medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundOvercrowding in emergency departments (EDs) due to injured patients who do not need urgent treatment can lead to less efficacious healthcare outcomes for those that do. The trauma referral audit (TRA) was developed to support medical staff and ensure that the injured receive treatment timely and efficiently.
methodsData on 14,399 injured patients referred to Maharaj Nakorn Chiang Mai Hospital between 2007 and 2017 were analyzed to examine the impact of the full TRA program implemented at the end of 2010. Injury severity was measured by using the injury severity score (ISS) whereby a score > 9 points infers severe injury. The impact of the establishment of TRA was examined using the trend of referrals and an interrupted time-series analysis of monthly mortality among patients with severe injury.
resultsThe median ISS of the patients in 2010 was 9 [4-18] and slightly increased to the highest score of 16 [8-25] in 2017. The proportion of patients with less severe injuries (ISS ≤ 9) decreased after the full implementation of TRA (55.4% in 2010 compared to 42.3% in 2017). Overall mortality was 6% (5.5% vs. 6.2% for the pre- and post-full TRA periods, respectively), and the mortality rate tended to increase from 4.77% in 2011 to 7.59 in 2017. The monthly mortality rate was estimated at 7.22% [95% confidence interval (CI) = 5.89-8.56%] with a significant increase of mortality in the post-full TRA period by 1.57% [0.16-2.98%] and in the annual trend of 0.11% [0.05-0.16%]. However, when considering severely injured patients only, the level and trend of the mortality rate were no different.
conclusionsAlthough the TRA program could help reduce patient overcrowding in EDs, it does not reduce the risk of mortality. Revision of the referral and in-hospital care guidelines accounting for these relevant factors might lead to a decrease in mortality.
