Abstract: Objective. Patient repositioning to offload high-pressure areas is an essential component of pressure ulcer prevention for bed-bound patients. In most settings, the quantity and quality of offloading and repositioning are difficult to measure. Real-time continuous bedside pressure mapping (CBPM) offers an opportunity to do so. Material and Methods. Data was collected on 627 patients being treated in a medical intensive care unit (MICU): 307 patients placed on beds with a CBPM system and 320 historical controls placed on the same beds without the CBPM system 1 year prior to the study participants. A pressure ulcer prevention bundle was enhanced by the addition of a CBPM system that provides real-time digital imaging of the patient on the support surface to National Pressure Ulcer Advisory Panel guidelines. Results. During the 2-month study period, 1 (0.3%) patient in the CBPM cohort developed a pressure ulcer compared with 16 (5%) patients in the historical cohort (P = 0.001). In a survey of the MICU care providers, 90% of respondents reported that the CBPM contributed to improved pressure detection and relief, 88% indicated the CBPM assisted them with repositioning protocols, and 84% reported the pressure map provided for more efficient and effective patient repositioning. Conclusion. Real-time, ongoing pressure measurement using a pressure-sensing mat may be a useful tool to help care providers effectively reposition patients within the context of existing standardized protocols for the prevention and minimization of pressure ulcers.
