AbstractBackgroundProne positioning has been widely used to improve oxygenation and reduce ventilator‐induced lung injury in patients with severe COVID‐19 acute respiratory distress syndrome (ARDS). One major complication associated with prone positioning is the development of pressure ulcers (PUs).AimThis study aimed to determine the impact of a prevention care bundle on the incidence of PUs in patients with COVID‐19 ARDS undergoing prone positioning in the intensive care unit.Study DesignThis was a single‐centre pre and post‐test intervention study which adheres to the Standards for Reporting Implementation Studies (StaRI) guidelines. The intervention included a care bundle addressing the following: increasing frequency of head turns, use of an open gel head ring, application of prophylactic dressings to bony prominences, use of a pressure redistribution air mattress, education of staff in the early identification of evolving PUs through regular and rigorous skin inspection and engaging in bedside training sessions with nursing and medical staff. The primary outcome of interest was the incidence of PU development. The secondary outcomes of interest were severity of PU development and the anatomical location of the PUs.ResultsIn the pre‐intervention study, 20 patients were included and 80% (n = 16) of these patients developed PUs, comprising 34 ulcers in total. In the post‐intervention study, a further 20 patients were included and 60% (n = 12) of these patients developed PUs, comprising 32 ulcers in total. This marks a 25% reduction in the number of patients developing a PU, and a 6% decrease in the total number of PUs observed. Grade II PUs were the most prevalent in both study groups (65%, n = 22; 88%, n = 28, respectively). In the post‐intervention study, there was a reduction in the incidence of grade III and deep tissue injuries (pre‐intervention 6%, n = 2 grade III, 6% n = 2 deep tissue injuries; post‐intervention no grade III ulcers, grade IV ulcers, or deep tissues injuries were recorded). However, there was an increase in the number of unstageable PUs in the post‐intervention group with 6% (n = 2) of PUs being classified as unstageable, meanwhile there were no unstageable PUs in the pre‐intervention group. This is an important finding to consider as unstageable PUs can indicate deep tissue damage and therefore need to be considered alongside PUs of a more severe grade (grade III, grade IV, and deep tissue injuries).ConclusionThe use of a new evidence‐based care bundle for the prevention of PUs in the management of patients in the prone position has the potential to reduce the incidence of PU development. Although improvements were observed following alterations to standard practice, further research is needed to validate these findings.Relevance to Clinical PracticeThe use of a new, evidence‐based care bundle in the management of patients in the prone position has the potential to reduce the incidence of PUs.
