Lopes, Palombo and Sabbatini have developed a system for computer-aided decision in nursing named ALTURIN.EXP, based on SABBATINI'S EXPERTMD system and the North American Nursing Diagnosis Association (NANDA) nursing diagnosis classification, which is related to nursing diagnosis for altered urinary elimination. The ALTURIN.EXP defines the specific altered urinary elimination diagnosis and indicates the most common nursing interventions. Our purpose was testing the program clinically. Twenty-nine cases of altered urinary elimination in women with gynecological and oncogynecological problems have been described. Three nurses provided the principal and secondary diagnoses when regarded. These diagnoses were compared to those of the program. As previously elaborated, the program, in some cases, provided the secondary diagnosis. The clinical cases use has led to a review on the program structure in order to decrease error possibility.50163-8
