Pressure ulcers and malnutrition frequently co-exist in frail patients. Nutritional parameters have been correlated with development and with healing in chronic pressure ulcers, leading to suggestions that improving nutritional status can prevent or treat pressure ulcers. Despite a strong association, a causal relationship of poor nutritional status to development of pressure ulcers has not been established. Support for a causal relationship would include evidence that nutritional interventions improve general nutritional status, acute wound healing, or chronic wound healing. The data suggesting that nutritional intervention can improve clinical outcome are limited. No study has demonstrated that improvement in nutritional status can prevent pressure ulcers. There is at least suggestive evidence that improvement in nutritional status can improve outcome in pressure ulcer healing.
压疮和营养不良在体弱患者中经常并存。营养参数与慢性压疮的发生和愈合相关，这使得人们认为改善营养状况可以预防或治疗压疮。尽管存在密切关联，但营养不良与压疮发生之间的因果关系尚未确立。支持因果关系的证据应包括营养干预可改善总体营养状况、急性伤口愈合或慢性伤口愈合的证据。表明营养干预可改善临床结局的数据有限。尚无研究表明营养状况的改善可预防压疮。至少有提示性证据表明营养状况的改善可改善压疮愈合的结局。
