Abstract
This paper describes a nursing fuzzy expert system for preventing pressure ulcer development in post-operative patients. First, knowledge of expert nurse for pressure ulcer development is derived. Second, a fuzzy expert system is constructed by a simple calculation of fuzzy membership functions expressing the knowledge. The expert system produces a fuzzy degree by averaging the calculated values obtained by these membership functions. This system performance is evaluated by leave-one-out cross validation on 10 patients. Then, the nursing fuzzy expert system can determine the pressure ulcer development with better precision, compared with the past work with statistical analysis on 360 patients.
