Evaluating the impact of a parent champion model on bronchiolitis hospitalisation rates: a difference in differences study.
Article in Archives of disease in childhood, 2026. 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
backgroundBronchiolitis and its outcomes have strong socioeconomic determinants. In Liverpool, a city with high deprivation and above-average bronchiolitis hospitalisations, we implemented the Respiratory Parent Champions in the Community intervention. Parent Champions were provided with training from paediatricians and community organisations. They delivered peer support and education around bronchiolitis and modifiable risk factors in local children's centres.
methodsUsing anonymised linked electronic health records for children born in Cheshire and Merseyside 2016-2023, we used inverse probability of treatment weighted difference-in-differences methods to compare the change in monthly bronchiolitis admissions after the intervention was introduced in the intervention cohort to the change in admissions in children living in other wards in the region that had not received the intervention, adjusting for differences between populations.
findingsEight Respiratory Parent Champions conducted 18 050 family contacts across 16 wards in Liverpool over a 24-month period. The intervention was associated with a reduction in emergency admissions of 128 per 100 000 children per month (95% CI 43 to 214, p<0.01), in comparison to the non-intervention cohort. This equates to a 23.8% reduction in admissions or a total of 107 (95% CI 36 to 179) admissions saved per year in the intervention cohort. The preliminary estimated cost of yearly admissions saved was £219 243, with a net saving of £101 283 per annum (-£44 196 to +£248 811) after accounting for the cost of employing Parent Champions.
interpretationThis study highlights the potential of a targeted community-led, co-produced intervention to alleviate healthcare burdens and address socioeconomic inequalities in infant respiratory illnesses.
