The impact of nutrition on pressure ulcer healing.

Pressure ulcers are debilitating and often painful problem, particularly in people who are elderly, immobile and/or obese. It is estimated that more than 100 000 new pressure ulcers develop each year. These wounds are caused by friction and shear and are particularly prevalent in older people, where malnutrition can be a factor in their development. Nutrition plays a key role in pressure ulcer care because wounds need both macronutrients and micronutrients to heal. It is essential that nurses understand the role of nutrition in pressure ulcer management.
