Incidence, characteristics and risk factors of endotracheal tube‐related pressure injuries in intensive care units

Abstract Background Medical devices commonly used for the treatment and care of critically ill patients can cause pressure injuries in intensive care units (ICUs). The endotracheal tube (ETT) is one of the most common medical devices to cause pressure injuries. Aim This study investigated the incidence of, characteristics of and risk factors for ETT‐related pressure injuries for ICU patients. Study Design This study adopted a prospective descriptive research design. The sample consisted of 146 endotracheally intubated patients. Data were collected using a patient information form, an Endotracheal Tube‐Related Pressure Injuries Assessment Form, the Braden Risk Assessment Tool and the Nutritional Assessment Test. Results The study revealed that 80.14% of the patients developed ETT‐related pressure injuries. Over half of the ETT‐related pressure injuries appeared on Day 3 or 4 (56.41%). High body mass index was found to be associated with the development of ETT‐related pressure injuries (OR: 1.15, 95% CI: 1.05–1.26, p = .003). None of the other variables were statistically significant in the development of pressure injuries. Conclusions The incidence of ETT‐related pressure injuries was quite high in the internal, surgical and anaesthesia ICUs. High body mass index was associated with the development of ETT‐related pressure injuries. Intensive care nurses should implement interventions to prevent ETT‐related pressure injuries in critically ill patients receiving mechanical ventilation support. Relevance to Clinical Practice ETT‐related pressure injuries are common in ICU patients. High body mass index was associated with the development of ETT‐related pressure injuries in critically ill patients. The skin and mucosa should be assessed for the development of ETT‐related pressure injuries during the daily assessment of the patients receiving mechanical ventilation support. The ETT should be repositioned regularly, and the most suitable ETT fixation method should be used.
