1 · What the graph read from it

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.

2 · The registry

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 seriously injured older adults are not transported to trauma centers (TCs), a phenomenon known as undertriage. System-level factors that contribute to undertriage are poorly understood. One important system-level factor is the regional supply of TCs. We hypothesized that regions with greater supply of TCs would have higher rates of transport to a TC for seriously injured older adults.

methodsIn this retrospective cross-sectional study using Medicare data from 2014 to 2015, we measured the proportion of seriously injured (injury severity score > 15) older adults (age ≥ 65 y) who were transported to a level I or level II TC within trauma service areas (TSAs), which consist of United States counties aggregated into contiguous geographic regions based on the most frequent hospital destinations for emergency conditions. Patients residing in rural regions were excluded. The primary outcome was transported to a level I or level II TC. The exposure was the supply of TCs within TSAs, grouped into terciles based on the number of TCs per capita. We performed a multivariable hierarchical logistic regression for the odds of TC transport with a random intercept for TSA and fixed effects for TC supply, patient demographics, and injury characteristics.

resultsOur study included 68,128 seriously injured older adults residing in 309 TSAs. The tercile of TSAs with the lowest supply of TCs had 1.13 TCs per 1,000,000 population, and 38.8% of seriously injured older adults were transported to a TC. In contrast, the tercile with the highest supply of TCs had 4.15 TCs per 1,000,000 population, and 68.5% were transported to a TC. On multivariable hierarchical logistic regression, TSAs with the highest supply of TCs had four times higher odds of transport to a TC compared to TSAs with the lowest supply of TCs (odds ratio 4.23; 95% confidence interval: 3.32-5.38; P < 0.001).

conclusionsOlder adults with serious injuries are more likely to be transported to a TC in TSAs with greater supply of TCs. Ensuring an appropriate supply of TCs within TSA regions may help to reduce rates of undertriage for seriously injured older adults.
