description: '**Concept**\r\nA pressure ulcer is localized damage to the skin and/or underlying tissue, often over a bony prominence, as a result of pressure or pressure combined with friction. \r\nA pressure ulcer involves a major disease burden and reduces the quality of life for a patient. Adequate risk evaluation, prevention and treatment of pressure ulcers can lead to a fewer incidences and prevalence of pressure ulcers.\r\n\r\n**Purpose**\r\nInformation on the pressure ulcer is of importance in starting or continuing the best possible wound treatment, curatively and preventatively, and to be able to properly monitor the wound healing process.\r\n**Evidence Base**\r\nTo describe the wound, there are 4 categories, based on the international NPUAP/EPUAP decubitus classification system: \r\n\r\n* Category 1: non-removable redness of intact skin;\r\n* Category 2: loss of a partial layer of skin or blister;\r\n* Category 3: loss of an entire layer of skin (visible fat);\r\n* Category 4: loss of an entire layer of tissue (visible muscle/bone).\r\n\r\n\r\n\r\n**Example Instances**' package_name: healthdata.be.r4.cbb derivation: specialization name: HdBePressureUlcer abstract: true type: https://fhir.healthdata.be/StructureDefinition/LogicalModel/PressureUlcer elements: Comment: short: Comment _definition: extension: -
