Shifting patterns in emergency department attendance: a time series analysis.
Article in Emergency medicine journal : EMJ, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundRising demand and limited capacity in primary care are often cited as reasons for the increasing pressure on emergency departments (EDs). The COVID-19 pandemic further strained but also reshaped healthcare services and their accessibility. However, an equally critical yet often overlooked factor is the increasing complexity of cases. This study assessed ED attendance trends for the Northwest London (NWL) population between February 2017 and September 2023, before, during and after the pandemic lockdown measures (March 2020-March 2021) in the UK as a whole and across sociodemographic and multimorbidity profiles.
methodWe used the Whole System Integrated Care data warehouse in NWL. We conducted a segmented time-series quasi-Poisson regression for weekly ED attendance for two periods, before and after the pandemic lockdown measures, adjusting for seasonality and autocorrelation. We stratified the model by age, sex and quintiles of the 2019 Index of Multiple Deprivation. We analysed ED attendance trends by multimorbidity groups.
resultsThere were 3 365 279 ED attendances from February 2017 to September 2023. Before the pandemic, there was a statistically significant annual growth rate of 3.4% (rate ratio (RR) 1.034; CI 1.026 to 1.042), with a rising trend in attendance observed in all patient groups. After the pandemic, the overall trend stabilised (RR 1.002; CI 0.993 to 1.009). However, attendances have continued to rise for older age groups (61-75 years and 76+ years) and have increased for patients with multimorbidity and complex multimorbidity. Meanwhile, attendance has declined for the least deprived. For the other patient groups, attendance has plateaued.
conclusionFollowing the pandemic, total ED attendances stabilised, but have continued to rise for older people, particularly those requiring complex care. This has implications for hospital capacity and places an increased strain on urgent and emergency care. We used high-quality representative population-level linked patient records data. The study was observational with limited causality. Further research should explore specific reasons behind these changes.
