Risk factors of medical device-related pressure injury in intensive care units

Objectives Intensive care unit (ICU) patients are at high risk of medical device related pressure injury (MDRPI). This study aims to ascertain the MDRPI prevalence in ICU patients and analyse the risk factors of MDRPI. Background The occurrence of MDRPI not only increases hospitalisation time with pain and economic burden, but also causes medical disputes. A better understanding of this condition will increase knowledge and facilitate the ability to recognise and prevent MDRPI for clinical nursing staff. However, there are few multicentre studies of MDRPI prevalence in ICU patients in China. Design A cross-sectional study design was employed. Methods Data from 694 patients in 66 adult ICU at 30 hospitals in China were included between October 2018 and March 2019. The stage of each MDRPI was determined according to the definitions of National Pressure Ulcer Advisory Panel. The study methods were followed by the STORBE guidelines. Results The overall prevalence rate of MDRPI was 13.1% (91/694), with 98 anatomic locations in total. The most common stages of MDRPI were stage 1 (54.1%, 53/98), stage 2 (15.3%, 15/98) and mucosal membrane pressure injury (15.3%, 15/98). MDRPI mainly occurred in the finger (32.7%, 32/98), followed by nose (18.4%, 18/98). The prevalence rate of MDRPI caused by CPAP or BiPAP masks (25%) was highest. Lower Braden scores and having skin oedema were risk factors for MDRPI in adult ICU patients. Conclusion The prevalence of MDRPI in this study was still high. Nurses should take these related factors into consideration when taking care of ICU patients, and appropriate prevention measures should be adopted to decrease the prevalence of MDRPI. Relevance to clinical practice: The study can help to improve the PI prevention efforts in ICU patients specific to medical device related PI.

Automated summary

This study conducted a cross-sectional study of 694 patients in 66 adult ICUs in 30 hospitals in China and found that the overall prevalence rate of MDRPI was 13.1%. Stage 1 MDRPI was the most common. CPAP or BiPAP masks were one of the main causes of MDRPI. Nurses should pay attention to lower Braden scores and skin edema as risk factors for MDRPI in adult ICU patients.
