The characteristic of the phased pressure ulcer care model lies in taking targeted preventive and therapeutic measures according to the different stages of pressure ulcer occurrence, thereby achieving early intervention, precise care and effective rehabilitation. This model divides the development of pressure ulcers into stages such as the skin erythema stage, the superficial injury stage, and the deep tissue injury stage, with different focuses on care in each stage.

During the erythema stage of the skin, the key points of care are stress relief, keeping the skin clean and dry, and improving local blood circulation. During the superficial injury stage, emphasis is placed on local protection, wound cleaning and dressing selection. During the deep tissue injury period, emphasis is placed on wound management, infection control and nutritional support. Staged care can effectively reduce the risk of pressure ulcer deterioration and accelerate the healing speed.

This model has prominent features: strong evidence-based nature, standardized operation, and high assessability. It is suitable for hospitals, long-term care institutions, and home care, and helps improve the quality of care and patient comfort.
