1 · What the graph read from it

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.

2 · The registry

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 characterise the clinical, microbiological and economic burden of hospital-admitted, injection-related infections among incarcerated people who inject drugs. STUDY TYPE: Retrospective observational cohort study.

settingSecure unit of the Princess Alexandra Hospital, Brisbane, Australia.

participantsAdults incarcerated in Queensland prisons who were admitted to hospital with an injection-related infection between 1 July 2019 and 30 June 2023.

main outcome measuresTypes of injection-related infection, microbiological findings, requirement for surgical or radiological source control, hospital length of stay and inpatient healthcare costs.

resultsThere were 321 hospital admissions for injection-related infection among 265 patients, accounting for 282 unique infections. Most patients were male (241; 90.9%), with a mean age of 33 years (standard deviation [SD], 7.4 years), and 76 (28.7%) identified as First Nations. The most frequent infections were soft tissue infections (77/282; 27.3%), acute hepatitis C (64/282; 22.7%) and cellulitis (43/282; 15.2%). Surgical or radiological source control was required in 95 infections (34.0%), and infectious diseases consultation occurred in 130 infections (46.1%). Among 39 true-positive blood cultures, Staphylococcus aureus was identified in 17 (43.6%), Burkholderia species in 10 (25.6%) and non-tuberculous Mycobacterium species in 3 (7.7%). Among the 218 non-acute hepatitis C infections, 50 (22.9%) were hepatitis C virus (HCV) RNA positive. Overall, HCV RNA was present in 114 of 282 infections (40.4%). The total inflation-adjusted inpatient cost was $8.39 million, with a median cost per infection of $11,602 (interquartile range, $7426-$34,544).

conclusionInjection-related infections among incarcerated people who inject drugs were associated with substantial morbidity and healthcare costs in this large hospital cohort. A wide clinical spectrum was observed, including atypical pathogens, and clinically overt acute hepatitis C requiring hospital admission. These findings describe a significant burden of preventable disease in custodial settings and support the introduction of established primary prevention and harm-reduction interventions in prisons.
