Pressure sore risk calculators have been identified as a useful tool in the preventative management of pressure sore development. Cubbin & Jackson (1991) believed that none of the many existing calculators were appropriate for the critically ill patients in intensive therapy units and adjusted an existing calculator to meet the needs of their patients. The Sunderland experience is a detailed account of a study which included a trial of Cubbin & Jackson's calculator, a critical analysis of the assessment criteria, and trial of a modified risk calculator. As accurate identification of at-risk patients increased the economic problem of supply/demand of specialised beds to reduce the risk of pressure sores raised many issues throughout the department. The study also included introduction of a wound management protocol and an efficient documentation system which has improved communication and continuity of care.
