The impact of interhospital transfer on mortality benchmarking at Level III and IV trauma centers: A step toward shared mortality attribution in a statewide system.
Article in The journal of trauma and acute care surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundMany injured patients presenting to Level III/IV trauma centers will be transferred to Level I/II centers, but how these transfers influence benchmarking at Level III/IV centers has not been described. We hypothesized that the apparent observed to expected (O:E) mortality ratios at Level III/IV centers are influenced by the location at which mortality is measured in transferred patients.
methodsWe conducted a retrospective study of adult patients presenting to Level III/IV trauma centers in Pennsylvania from 2008 to 2017. We used probabilistic matching to match patients transferred between centers. We used a risk-adjusted mortality model to estimate predicted mortality, which we compared with observed mortality at discharge from the Level III/IV center (O) or observed mortality at discharge from the Level III/IV center for nontransferred patients and at discharge from the Level I/II center for transferred patients (O).
resultsIn total, 9,477 patients presented to 11 Level III/IV trauma centers over the study period (90% white; 49% female; 97% blunt mechanism; median Injury Severity Score, 8; interquartile range, 4-10). Of these, 4,238 (44%) were transferred to Level I/II centers, of which 3,586 (85%) were able to be matched. Expected mortality in the overall cohort was 332 (3.8%). A total of 332 (3.8%) patients died, of which 177 (53%) died at the initial Level III/IV centers (O). Including posttransfer mortality for transferred patients in addition to observed mortality in nontransferred patients (O) resulted in worse apparent O:E ratios for all centers and significant differences in O:E ratios for the overall cohort (O:E, 0.53; 95% confidence interval, 0.45-0.61 vs. O:E, 1.00, 95% confidence interval, 0.92-1.11; p < 0.001).
conclusionApparent O:E mortality ratios at Level III/IV centers are influenced by the timing of measurement. To provide fair and accurate benchmarking and identify opportunities across the continuum of the trauma system, a system of shared attribution for outcomes of transferred patients should be devised.
