A retrospective cohort study of hospital-acquired pressure injuries (HAPI) reported an incidence rate of 34.3% based on 582 medical records of adult patients admitted to the intensive care unit (ICU) of a medium-complexity public hospital in 2017 and 2018. Sixty percent of the patients used respirators, 49.3% presented hypotension, and 48.1% used norepinephrine. The main individual predictors of HAPI in the ICU were "days of norepinephrine" with an odds ratio (OR) of 1.625 (95% CI: 1.473-1.792) and concordance statistic (AUC) of 0.818 (95% CI: 0.779-0.857), "days of mechanical ventilation" with an OR of 1.521 (1.416-1.634) and AUC of 0.879 (0.849-0.909), "ICU stay (days)" with an OR of 1.279 (1.218-1.342) and AUC of 0.846 (0.812-0.881), and "Braden's sensory perception" with an OR of 0.345 (95% CI: 0.278-0.429) and AUC of 0.760 (0.722-0.799). The duration of mechanical ventilation, norepinephrine administration, and ICU length of stay presented significant discriminative capacity for HAPI prediction.

Impact of multifaceted interventions on pressure injury prevention: a systematic review.
BMC Nurs
January 2025
Department of Adult Health Nursing, College of Health Sciences, Arsi University, Asella, Ethiopia.
Background: Pressure injuries are a significant concern in healthcare settings, leading to increased morbidity, healthcare costs, and patient suffering. This systematic review aims to evaluate the impact of multifaceted interventions on the prevention of Pressure injuries and improvements in nursing practices.
Methods: A systematic search was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across multiple databases, including studies from Google Scholar (332), Science Direct (14), grey literature sources (45), PubMed (0), Cochrane Library (437), and Hinari (322).
The 'HAPI' project five years on: Incidence and prevalence of Hospital-Acquired Pressure Injuries in one local health district in Australia.

Aim: From 2015 to 2018, the 'Hospital-Acquired Pressure Injury (HAPI)' project was implemented in one local health district in Australia and utilised an implementation science approach to address rising pressure injury (PI) incidence and prevalence rates. This paper aims to examine whether the project was successful in sustaining low PI incidence and prevalence rates over the five-years following implementation (spanning the 2018/2019 to 2022/2023 financial years and the 2019-2023 calendar years).
Materials And Methods: A retrospective cohort study was conducted involving a comprehensive analysis of HAPI incidence, prevalence, and hospital-acquired complication (HAC) data spanning 5 years (incidence and HAC: 2018/2019 to 2022/2023 financial years; prevalence: January 2019 to December 2023 calendar years) post-implementation of the HAPI project.
A Three-Year Analysis of Mortality in Clostridioides difficile Patients in a Tertiary Center.

Background/objectives: , an anaerobic bacillus ubiquitous in nature, is the leading cause of hospital-acquired diarrhoea and one of the main causes of mortality by nosocomial infections. We aimed to identify the main predictors of the risk of dying and the characteristics of a three-year cohort of patients hospitalised in our clinic that eventually had an unfavourable outcome.
Methods: We collected retrospectively available data for all patients hospitalised between January 1, 2021, and December 31, 2023.
Prediction of stroke-associated hospital-acquired pneumonia: Machine learning approach.

Article Synopsis
- Stroke-associated Hospital Acquired Pneumonia (HAP) is a serious concern for stroke patients, and this study investigates using machine learning to predict its occurrence based on national registry data.
- The research involved analyzing data from nearly 10,000 stroke patients and comparing the performance of various machine learning models, with the Artificial Neural Network (ANN) achieving the best results.
- Key predictors for HAP were identified through SHAP analysis, indicating that factors like stroke severity and arrival method significantly affect the risk of developing HAP, highlighting the potential for improved patient care through predictive modeling.
