Prevalence of chronic wounds in hospitalised patients in Catalonia, Spain: a multicentre cross-sectional descriptive observational study

# metadata.dc.description.abstract[].value
Background Few studies have investigated the prevalence of chronic wounds and the clinical and sociodemographic characteristics of hospitalised patients affected by them. Understanding these characteristics within the inpatient setting can support improved follow-up, inform care strategies, enhance quality and safety and reduce associated healthcare costs. This study aimed to determine the prevalence and the sociodemographic profile of adult inpatients with chronic wounds admitted to the eight hospitals of the Catalan Institute of Health between 2016 and 2020. Methods A descriptive, observational, cross-sectional and retrospective multicentre study was conducted using routinely collected clinical data from 1 January 2016 to 31 December 2020. The study encompassed hospital wards, step-down units and home hospitalisation services across eight public hospitals managed by the Catalan Institute of Health, the main public healthcare provider in Catalonia, Spain. The study included all patients aged 18 years or older who were hospitalised with chronic wounds during the study period. The main variables were nursing diagnoses of chronic wound types: pressure injuries (PIs), arterial ulcers (AUs), venous ulcers (VUs), mixed ulcers and diabetic foot ulcers (DFUs), as recorded in nursing electronic health records. Secondary variables included age, sex, reason for admission, unit of admission, hospital type, source of admission and discharge destination. A descriptive and comparative analysis was performed. Results Among 796 698 hospitalised patients, 16 935 (2.1%) presented with at least one chronic wound. The most common types of chronic wounds were PIs and AUs. A slight decline in the prevalence of chronic wounds was observed over the study period. Cardiovascular and respiratory conditions were the leading causes of admission among these patients. AUs and DFUs were more prevalent in men, whereas VUs were more frequently observed in women. Patients with PIs had longer hospital stays, higher rates of intensive care unit admissions and increased in-hospital mortality. In contrast, patients with vascular ulcers more often required continued care after discharge (p<0.001). Conclusions Chronic wounds continue to represent a significant healthcare challenge. It is essential to consider the clinical characteristics and health outcomes of hospitalised patients with chronic wounds in order to improve care quality and safety. Further research is warranted to explore the relationship between patient care complexity and the type of chronic wounds present.
