Abstract
The study aims to follow up on the analysis of Pressure injuries (PIs) prevalence conducted between 2007 and 2014 and after the new methodological requirements for PIs surveillance establishment at the national level. A retrospective, nationwide cross-sectional analysis of data regarding the STROBE checklist was collected by the National Health Information System (NHIS). The International Classification of Diseases (ICD-10) diagnoses L89.0-L89.9 for PIs were used in the period 2010-2019. A total of 264 442 records of patients with diagnoses of L89.0-L89.9 were identified from 2010 to 2019 (26 444 patients per year on average). The numbers are increasing every year, and there is a 40% increase between 2010 and 2019. When comparing recorded PIs, the percentage of PIs occurrence in category I decreased, and the number of PIs in category IV increased in the second analysed period. Still, in absolute numbers, there is an increase across all categories. The age of patients with recorded PIs also rose slightly in the second analysed period. We have proven the PIs prevalence increase in an ageing population.
