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

objectivesAssess the effects of Age, Period and Cohort (APC) in the trends in emergency department (ED) visits in 2003-2023 in Australia.

methodsFor this retrospective observational study, we obtained data on all ED visits in Australia in 2003-2023 from the Australian Institute of Health and Welfare and applied an APC model to separate Age, Period and Cohort effects.

resultsThe total number of ED visits increased from 4,306,183 in 2003 to 7,194,861 in 2013 (67% increase). A 25% increase was observed in 2013-2023 (n = 9,014,526 visits in 2023). Rates of ED visits have increased in Australia in 2003-2023 from 218 per 1000 residents to 338 per 1000. Rates of ED visits were higher in patients aged > 85 years and have increased in 2003-2023 from 525 per 1000 to 835 per 1000 (59% increase). The increase in the number of ED visits per capita was slightly lower in those aged 65-74 (from 226 per 1000 in 2003 to 338 per 1000 in 2023, 50% increase) and those aged 75-84 years (350 per 1000 to 526 per 1000, 50% increase) compared to residents aged > 85 years.

conclusionsOur APC modelling shows a deceleration in the increase in the rate of ED visits in the last decade, despite at the same age younger generations having higher rates of ED visits than older generations. The consistent increase in ED visits per capita in those aged < 75 years has major implications for healthcare planning and policies needed to reduce ED demand.
