Pressure injuries as adverse events in the context of patient's safety during 2013-2020 in a specialist hospital: A retrospective study.
Article in PloS one, 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
backgroundHospital-acquired pressure injuries (HAPIs) are recognized as potentially preventable adverse events and important indicators of patient safety and healthcare quality. However, evidence regarding their occurrence within hospital adverse event reporting systems remains limited.
objectiveTo assess the occurrence of hospital-acquired pressure injuries recorded as adverse events and to identify factors associated with their occurrence. MATERIALS AND
methodsThis retrospective study was conducted at a hospital in Kraków, Poland. A total of 1,272 adverse event reports recorded between 2013 and 2020 were reviewed. Among these, 305 hospital-acquired pressure injuries (HAPIs) were identified. A comparison group of hospitalized patients without HAPIs was selected for comparative analyses. Clinical and demographic information was extracted from patients' medical records.
resultsBetween 2013 and 2020, a total of 1,272 adverse events were recorded, representing 1.16% of all hospitalizations during the study period. Hospital-acquired pressure injuries (HAPIs) accounted for 24.0% (305/1,272) of all reported adverse events. Compared with the comparison group, patients with HAPIs had significantly longer hospital stays (18.64 ± 13.51 vs. 12.62 ± 7.81 days; p < 0.001) and were prescribed a significantly higher number of medications (18.14 ± 9.03 vs. 10.43 ± 7.90; p < 0.001). The highest number of adverse events was reported in the Internal Medicine and Allergology Ward. In multivariable analysis, older age, prolonged hospitalization, a higher number of prescribed medications, and greater comorbidity burden were independently associated with HAPI occurrence.
conclusionsHospital-acquired pressure injuries are recognized as an important indicator of patient safety and healthcare quality. Their occurrence was significantly associated with prolonged hospitalization and greater pharmacological burden, suggesting an increased risk among patients with higher clinical complexity. Systematic monitoring of HAPIs within hospital adverse event reporting systems may facilitate the identification of high-risk patients, support targeted preventive interventions, and contribute to improvements in patient safety.
