The Rice score is a tool used to predict the likelihood of developing a pressure ulcer. It is based on four factors: the patient's age, the patient's mobility, the patient's nutrition, and the patient's incontinence. The score is calculated by adding the points for each of these factors. A score of 0-3 is considered low risk, 4-6 is considered moderate risk, and 7-10 is considered high risk.The Rice score is a tool used to predict the likelihood of developing a pressure ulcer.
