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

backgroundAlthough many countries have reformed public hospitals to reduce the imbalance of resources, there is limited information on the impact of hospital restructuring on communities and the regional healthcare system. The present study aimed to examine the effects of public hospital restructuring on the admission of elderly residents.

methodsWe analyzed a public hospital restructuring case in a secondary medical service area (SMSA) in Japan using administrative claims data. All consecutive patients aged 65 years or older who resided in the SMSA and were admitted to a hospital or visited a hospital between 36 months prior and 48 months after the restructuring were included. Effects of the restructuring on monthly admissions within the SMSA were evaluated using a segmented Poisson regression model and interrupted time-series analysis.

resultsA total of 58,929 admissions were analyzed. After the restructuring, admissions within the SMSA increased and reached the same level of admissions outside the SMSA. Interrupted time-series analyses revealed level (incidence rate ratio (IRR) 1.097, 95% confidence intervals (CI) 1.039–1.159, + 10.3% in two months) and slope (IRR 1.005, 95% CI 1.003–1.007, + 7 per month) changes in monthly admissions within the SMSA after the restructuring.

conclusionsMonthly admissions of elderly residents within the SMSA increased after hospital restructuring, underscoring the importance of examining admissions within the neighborhood when assessing the impact of public hospital restructuring.
