Impact of COVID-19 infection on social care use in people over 50 years of age: a matched cohort study in North-West London.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo estimate the impact of COVID-19 infection on the requirement for social care services among adults aged ≥50 years in North-West London.
designPopulation-based matched cohort study using linked routinely collected electronic social care, primary care and hospital records (the Discover dataset).
settingApproximately 4.7 million people with a general practitioner record in North-West London.
participants150 654 adults aged ≥50 years with a first diagnosis of COVID-19 between January 2020 and February 2023 and 547 704 propensity score matched comparators without a COVID-19 diagnosis during the same period.
main outcome measuresSocial care use and associated costs overall and by specific type (care home, domiciliary care, respite care, social care assessments) stratified by age group, index year, diagnosis setting, severe COVID-19 risk status, frailty and care home admission prior to index. Overall survival was also assessed.
resultsA total of 9174 (6.09%) individuals with COVID-19 required social care use (of any type) during follow-up, 2.54 times (95% CI 2.48 to 2.61; p<0.0001) higher than matched comparators (n=13 126, 2.40%). The difference was largest for care home admission; individuals with COVID-19 had 4.10 (95% CI 3.87 to 4.36; p<0.0001) times the risk of a care home admission and nearly twice the risk (risk ratio 1.94; 95% CI 1.86 to 2.02; p<0.0001) of domiciliary care during follow-up compared with matched comparators. Individuals with COVID-19 experienced higher mortality, with 9.30% (14 005/547 704) dying during follow-up compared with 3.76% (20 608/547 704) deaths among matched comparators.This increase in social care utilisation was observed for all age groups. Adults with COVID-19 had over four times higher social care costs than matched comparators (£1276 per person per year (pppy) vs £276 pppy; mean difference +£1000, 95% CI £947 to £1054, p<0.0001), with most of the costs due to care home admissions. Higher social care costs in individuals with COVID-19 compared with matched comparators were strongly age related, rising from a mean difference of £130 pppy (95% CI £99 to £161) in those aged 50-64 to £6108 pppy (95% CI £5613 to £6603) higher costs in those aged ≥85.
conclusionsCOVID-19 infection is associated with meaningfully higher social care requirements in the ≥50 years population. Reducing the need for social care use and the associated costs of care should be one of the goals of interventions to reduce the risk and severity of COVID-19 infection.
