Medical device-related pressure injuries in intensive care patients: A prospective and descriptive study

Abstract

BackgroundTreatment and care of patients in intensive care units require the use of many medical and technological instruments. Pressure injuries occur when medical devices, which are used more in intensive care patients and are in direct or indirect contact with the skin, cause focal and localized forces on the superficial or deep tissues. ObjectiveIn this study, it was aimed to examine the risk factors, incidence and characteristics of medical device-related pressure injuries in intensive care patients. MethodsThis study has a prospective and descriptive design. The study was carried out in the adult intensive care unit of a healthcare institution located in the western Turkey. 138 intensive care patients treated in the level 3 adult intensive care unit were enrolled in the study. The first observations and evaluations of intensive care patients in terms of pressure injuries were made within the first 24 h after admission to the clinic. Observations continued daily during the hospitalization period of the patient. Data were collected with the Intensive Care Patient Information Form, Glasgow Coma Scale, Braden Pressure Ulcer Risk Assessment Scale and Identification Form for Medical device-related Pressure Ulcers. Analysis of data was performed with descriptive statistical methods, Shapiro-Wilk Test, Mann-Whitney U Test and Chi-Square analysis. ResultsMedical device-related pressure injury developed in 11.6% (n = 16) of intensive care patients. Anatomically, pressure injury occurred most frequently on the lip (37.5%) and most frequently due to the intubation tube (37.5%). Most of the developed wounds (75.0%) were found to be stage 2. Multinominal logistic regression analysis, which was performed to determine the effect of independent variables on medical device-related pressure injuries in intensive care patients, was found to be statistically significant (X2 = 37.098, p < 0.001). When the regression coefficients were examined, it was found that total hospitalization time in the intensive care unit (β = 0.948, p < 0.01) and PaCO2 level (β = 0.923, p < 0.01) had a positive, and duration of aerobic respiration with nasal cannula or mask (β = −0.920, p < 0.01) and Braden score (β = −0.948, p < 0.01) had a negative and significant effect on medical device-related pressure injuries. ConclusionsIn this study found that the MDRPIs development rate was lower than other studies. It was observed that pressure injuries due to medical devices developed more frequently in patients with longer hospitalization days, higher PaCO2 levels, shorter duration of oxygenated breathing with nasal cannula or mask, and lower Braden scores.
