CONCLUSION This is the first reported use of cytokine adsorption for CRS showing efficacy in absorption of various cytokines but not endothelial growth factors. A randomized controlled trial to evaluate additional Cytosorb treatment in CRS is currently recruiting at our institution (NCT04048434). BACKGROUND Pressure injuries are frequently occurred adverse events in hospitals, affecting the well-being of patients and causing considerable financial burden to healthcare systems. However, the estimates of prevalence, incidence and hospital-acquired rate of pressure injury in hospitalised patients vary considerably in relevant published studies. OBJECTIVES To systematically quantify the prevalence and incidence of pressure injuries and the hospital-acquired pressure injuries rate in hospitalised adult patients and identify the most frequently occurring pressure injury stage(s) and affected anatomical location(s). DESIGN Systematic review and meta-analysis. DATA SOURCES Medline, PubMed, Embase, Cochrane Library, CINAHL and ProQuest databases from January 2008 to December 2018. REVIEW METHODS We included studies with observational, cross-sectional or longitudinal designs, reporting pressure injury among hospitalised adults (≥16 years) and published in English. Outcomes were point prevalence, incidence of preneity was noted across some geographic regions. Meta-regression showed that the year of data collection, mean age and gender were independent predictors, explaining 67% variability in the prevalence of pressure injuries. The year of data collection and age alone explained 93% of variability in hospital-acquired pressure injuries rate. CONCLUSION This study suggested that the burden of pressure injuries remains substantial with over one in ten adult patients admitted to hospitals affected. Superficial pressure injuries, such as
