Estimating the scale of hospital admissions for people experiencing homelessness in England: a population-based multiple systems estimation study using national Hospital Episode Statistics.
Article in BMJ public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: People experiencing homelessness have substantial health needs and poor access to primary healthcare, resulting in high rates of hospital care. Housing status is not routinely recorded in English electronic health records, undermining service planning. We developed methods to estimate the scale of hospital admissions for people experiencing homelessness in England. Methods: We analysed admissions for people experiencing homelessness using Hospital Episode Statistics for 2013/2014, 2015/2016 and 2017/2018. We applied multiple systems estimation Poisson regression methods to estimate total admissions and an inflation factor to correct for under-reporting. We calculated unadjusted admission rates per 1000 population per year and admission rate ratios compared with the housed population. Results: We observed 34 790 admissions in 2017/2018, with total homeless admissions estimated at 176 342 (95% CI 164 031 to 188 654) (inflation factor=5.07 (95% CI 4.71 to 5.42)). The unadjusted admission rate for the 2017/2018 homeless population was 879.0 admissions per 1000 population per year (95% CI 817.7 to 940.4), 2.5 (95% CI 2.3 to 2.7) times higher than the housed population. Restricted to rough sleepers and hostel residents, the unadjusted rate was 3516.7 per 1000 (95% CI 3271.2 to 3762.2), with a rate ratio of 10.0 (95% CI 9.3 to 10.7) compared with the housed population. Conclusions: We estimated five times as many hospital admissions for people experiencing homelessness than we observed directly. We advise caution when applying these inflation factors to other datasets because of methodological limitations in this study and sensitivities to local coding practices. In the absence of routine housing status recording, multiple systems estimation could facilitate improved service planning.
