How can I effectively assess the severity of a pressure ulcer in a community-dwelling patient?

To effectively assess the severity of a pressure ulcer in a community-dwelling patient, start with a comprehensive skin assessment performed by a trained healthcare professional. This assessment should include checking skin integrity at pressure sites, noting any colour changes or discolouration, and identifying non-blanchable erythema, which may present differently in darker skin tones. Use finger palpation or diascopy to determine if erythema or discolouration is blanchable. Document the surface area of the ulcer using validated measurement techniques such as transparency tracing or photography, and estimate the depth and presence of undermining. Categorise the ulcer using a validated classification system like the International NPUAP-EPUAP Pressure Ulcer Classification System to guide management and prevention strategies. Repeat and document the assessment regularly to monitor changes. Additionally, consider any pain or discomfort reported by the patient during the assessment. This thorough approach ensures accurate determination of ulcer severity and informs appropriate care planning.
