The Relationship Between the Use of Pressure Sensing Dressings, Development of Pressure Injuries, and Length of Healing: A Cross-Sectional Study of Randomized Controlled Trial Data
by Dudziak, Sandra, Ph.D., Trident University International, 2020, 116; 28091894
Abstract (Summary)

Background: Prevention of pressure injuries may be difficult due to the complexity and disease process of patients in long term care facilities. A pressure sensor dressing may assist in further understanding of the pressure over time impact on different bony prominences and providing individualized care in pressure injury prevention. In the daily care and treatment of the patients at risk for pressure injuries, different support surfaces (foam or air loss) were designed to support the prevention or closure of pressure injuries. The PressureAlert device provides the pressure mapping for foam or air surfaces as part of the daily individual treatment for patients.

Objective: The objective of this study was to examine whether PressureAlert measurement pressure mapping was associated with the occurrence of pressure injuries, pressure injury closure time, and Braden scores to assist nurses in the reduction of pressure injuries and selection of proper support surfaces.

Design: A cross-sectional design utilizing secondary analysis of Randomized Controlled Trial (RCT) data was selected as the optimal approach to investigate the application of the PressureAlert device on patients and the development of pressure injuries on specific bony prominences (sacrum or heels). The use of the PressureAlert device was also examined in the scope of time to closure of pressure injuries and, specifically, whether the device was significantly associated with reduction in time to closure of existing pressure injuries. Further, this study investigated and explored the potential influence of the PressureAlert device on the prevention and management of pressure injuries in high-risk patients living in long-term care facilities.

Results: The pressure sensing device, PressureAlert, significantly reduced the number of pressure injuries and significantly reduced the number of days for wound closure. The investigation demonstrated a significantly lower proportion of overall facility acquired injuries and ulcers in the experimental group compared to the control group (0% versus 18%; p =.001). Furthermore, the number of days to wound closure was also significantly lower for the experimental group compared to the control group, F(1, 56) = 7.275, p < .001, indicating that the use of PressureAlert device had a statistically significant impact on wound closure. There was also a strong correlation between Braden scores and patients with pressure injuries, χ2(1, N = 121) = .324, p < .001.

Conclusion: Pressure sensing dressing (PressureAlert) has a favorable impact on the prevention of pressure injuries and days of wound closure for high-risk patients of long-term care facilities.
