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

backgroundThe number of calls for ambulances in Australia has been rising faster than population growth, but it is unclear what is driving this demand. This study aims to quantify and compare the drivers of emergency ambulance demand in Victoria, Australia, before and after the COVID-19 pandemic, including demographic and clinical factors.

methodsWe conducted a retrospective cohort study of all emergency ambulance calls in Victoria from January 1, 2016, to December 31, 2023. Using negative binomial segmented time series regression models, adjusted for population growth and seasonality, we estimated trend and level changes across demographic and clinical subgroups.

results5,239,378 calls were analysed. Ambulance demand increased annually by 4.3% [95% CI 3.6,5.1] pre-COVID-19, but slowed to 2.7% [95% CI 0.9, 4.5] post-pandemic. Post-COVID-19, there was a decreasing trend in calls among children, rural residents, and patients with lower socioeconomic advantage. The trend in demand also declined for calls related to chest pain, cardiac arrest, and falls. In contrast, there was an increasing trend among older adults and for complaints including headaches, heart problems, and trauma. Psychiatric calls showed continued growth across all periods, despite a level decrease at the end of COVID-19.

conclusionsAltered patterns of ambulance utilisation were observed in Victoria post-COVID-19. Reduced demand growth post-COVID-19 may reflect a diversion toward urgent care centres and the growing role of telehealth. Ongoing increases in psychiatric demand highlight the need for system-level interventions to manage mental health presentations. Calls for falls increased proportionally with population growth, indicating that falls are not a significant driver of ambulance demand.
