However, evidence regarding their occurrence within hospital adverse event reporting systems remains limited.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To assess the occurrence of hospital-acquired pressure injuries recorded as adverse events and to identify factors associated with their occurrence.<\/jats:p>\n <\/jats:sec>\n \n Materials and methods<\/jats:title>\n This retrospective study was conducted at a hospital in Krak\u00f3w, 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\u2019 medical records.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Between 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\u2009\u00b1\u200913.51 vs. 12.62\u2009\u00b1\u20097.81 days;\n p<\/jats:italic>\n \u2009<\u20090.001) and were prescribed a significantly higher number of medications (18.14\u2009\u00b1\u20099.03 vs. 10.43\u2009\u00b1\u20097.90;\n p<\/jats:italic>\n \u2009<\u20090.001). 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.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Hospital-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.<\/jats:p>\n
