Ohura et al developed a simple scale for evaluating a patient for the risk of developing a pressure ulcer. This also correlates with the time necessary for the ulcer to resolve.
(1) self-sustainability (ability to be involved in activities of daily living)
(2) morbid bony prominence
(4) articular contraction
total score =
= SUM(points for all 4 parameters)
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk of developing a pressure ulcer and the longer it will take to resolve.
