Explanation
The Waterlow score is a tool used to assess the risk of development of a
pressure sore. It utilises the following parameters to risk-stratify the patient:
body weight, nutritional status, continence, skin type, mobility, age and sex. It
may be used both in an acute setting or in care homes.
