Estimating national prevalence of life-limiting conditions amongst infants, children, and adolescents using administrative hospital data in the absence of a unique health identifier; evidence from Ireland.
Article in BMC pediatrics, 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
backgroundEstimating the total number of children with a life-limiting, complex chronic condition or serious illness has been identified as an important first step in determining how many children might need palliative care in a country or region. Relevant estimates have not been calculated for Ireland, an exercise complicated by the country's lack of a fully operational unique patient identifier in healthcare data.
methodsThis study estimated prevalence of life-limiting conditions amongst children aged 0-19 in Ireland in 2019 and 2024, demonstrating methods in the absence of a unique identifier. Baseline hospital-based prevalence calculated as (estimated) number of inpatients with a life-limiting diagnoses per 10,000 population aged 0-19 in Ireland, 2019 (pre-Covid) and 2024 (most recent year available). Number of inpatients were estimated from discharge-level data under 3 alternative scenarios (E1, E2, E3) adjusting for multiple admissions in the data. In sensitivity analysis, adjusted prevalence estimates further corrected for sources of under-counting in the data.
resultsBaseline estimated total prevalence of life-limiting conditions amongst children aged 0-19 in Ireland between 34.8 (E3) and 50.0 (E1) per 10,000 population in 2019; between 32.3 (E3) and 44.5 (E1) per 10,000 population in 2024. In sensitivity analysis, correcting for potential under-counting in the data, adjusted estimated prevalence: between 46.4 (E3) and 66.6 (E1) per 10,000 population in 2019; and between 43.0 (E3) and 59.3 (E1) per 10,000 population in 2024. Prevalence was higher for males than for females, and highest in the age group < 1 for all estimation scenarios.
conclusionsThese are the first estimates of prevalence of life-limiting conditions amongst children in Ireland that have been calculated using Irish-specific hospital data. The estimates are in line with prevalence from other similar-income countries based on studies using similar definitions and methodologies. The findings demonstrate how careful application of transparent methods to routinely collected administrative hospital activity data can yield important findings even in the context of data limitations.
