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

backgroundLow socioeconomic status (SES) is a known determinant for higher disease incidence and adverse health outcomes. However, the geographical distribution of SES and its impact on intensive care unit (ICU) populations remains unclear. This study aims to examine SES differences across Dutch acute care regions, hospital types, and patient characteristics and to build a national ICU cohort to improve comparisons of intensive care quality and identify potential health inequalities.

methodsA nationwide cohort study was conducted, linking clinical data of the National Intensive Care Evaluation registry from all Dutch ICU admissions (2014-2022) with SES scores from Statistics Netherlands. The SES score was based on wealth, education, and employment component scores per household. SES distributions were compared across regions, hospital types and volumes, admission types, and number of chronic conditions.

resultsOf 623,838 eligible ICU admissions, 588,568 (94.3%) were successfully linked to SES scores. Differences in SES were observed between regions. The Southwest and Limburg regions showed the lowest mean SES, while Middle and Zwolle regions showed the highest. Lower SES was observed in admissions to non-academic hospitals, smaller volume hospitals, medical admissions, and patients with chronic conditions.

conclusionDespite the robust healthcare system, socioeconomic disparities were observed among Dutch ICUs and regions in this novel ICU cohort, highlighting the importance of considering SES when comparing ICUs. Our findings underscore the need for further research into the effects of SES on ICU outcomes within this and other cohorts, including studies in different countries. Additionally, these results suggest that incorporating SES into the ICU performance benchmarking is crucial for fair comparisons across diverse healthcare settings.
