Exploring medical device-related pressure injuries in a single intensive care setting: A longitudinal point prevalence study

Objectives: To report longitudinal prevalence rates of device-related pressure injuries in critically ill adult patients in the intensive care unit and to explore the patient characteristics associated with the development of device related pressure injuries. Research design: A prospective observational design where observations of patients' skin integrity were conducted on one day each week for 52 weeks. Setting: The study was conducted in the 36-bed intensive care unit of a major metropolitan tertiary referral hospital in Queensland, Australia. The sample included all patients aged 18 years or older admitted to the intensive care unit before midnight on the day preceding the observation, with a medical device in situ. Main outcome measures: The primary outcome pleasure was device related pressure injuries identified at the weekly observations and defined as a pressure injury found on the skin or mucous membrane with a history of medical device in use at the location of the injury. Patient demographic and clinical characteristics were recorded. Results: Over the study period, 11.3% (71/631) of patients developed at least one hospital-acquired ORPI. The most common devices associated with injury were nasogastric/nasojejunal tubes (41%) and endotracheal tubes (27%). Significant predictors of device related pressure injuries were the total number of devices (OR 1.230, 95% CI 1.09-1.38, p < 0.001), the length of time in the ICU (OR 1.05, 95% CI 1.02-1.09, p = 0.003), male sex, (OR 2.099, 95% CI 1.18-3.7, p = 0.012), and increased severity of illness score on admission (OR 1.044, 95% CI 1.01-1.09, p = 0.013). Conclusion: Device related pressure injuries are an all-too-common iatrogenic problem for this vulnerable patient cohort.

Automated summary

This study reported longitudinal prevalence rates of device-related pressure injuries in critically ill adult patients in the intensive care unit and identified significant predictors including total number of devices, length of ICU stay, sex, and severity of illness score on admission. Device related pressure injuries are a common iatrogenic issue for this vulnerable patient cohort.
