Pressure ulcers related to prone positioning: a pandemic amidst a pandemic

Abstract

Objective: To explore the epidemiology and risk factors associated with the development of pressure ulcers (PUs) in patients receiving prone positioning (PP) ventilatory therapy; to compare the inflammatory status of patients who develop PUs with those who do not; and to describe the experience and useful findings that have allowed us to improve the management of these patients to reduce the incidence of PUs. Method: An observational, descriptive and longitudinal study was conducted, where sociodemographic and laboratory data were collected from patients who were hospitalised and required PP ventilatory therapy in critical care areas (CCA) during the months of May–October 2020. Results: From the total number of patients who required PP during their CCA stay (n=240), 202 (84.2%) developed a PU. The four most frequent areas where a PU appeared were: the head and neck (n=115); the pinna (n=21); the torso (n=21); and the lower limbs (n=21). Patients who developed PU were more frequently males with higher initial levels of creatinine phosphokinase and ferritin. The incidence for each month of follow-up decreased from 8.3% to 5.8%. Conclusion: Regardless of the intervention, a multidisciplinary approach is required to optimise the prevention and treatment of these wounds. While PUs are often the result of other medical conditions or poor health status in general, the vast majority of PUs are avoidable.
