Avaliação de um sistema especialista em diagnóstico de enfermagem relacionados à eliminação urinária

Abstract

An expert system on nursing diagnoses related to urinary elimination, according NANDA's taxonomy, was developed and evaluated. Data were collected using a form and a checklist of defining characteristics. The obtained consensus diagnoses by three specialists were considered gold standard. 197 cases were tested. The system proved to be adequate for determining diagnoses such as 'stress urinary incontinence', 'urge urinary incontinence', 'urinary retention' and 'total urinary incontinence' with sensitivity and specificity above 98%. The accuracy evaluation in relation to 'impaired urinary elimination', 'reflex urinary incontinence' and 'functional urinary incontinence' was not possible to be established due to the small size of the sample. The experience in developing and evaluating this program can be applied in creating other expert systems.

Urinary incontinence nursing diagnoses in patients with stroke

“…The parameters for calculating the sample were: confidence level of 95% (Zα), sampling error of 7%, and the prevalence was based on a study (11) that had a value of 27% for the nursing diagnosis of Stress urinary incontinence. This nursing diagnosis was adopted for calculation because it was the only one that had been investigated with an estimated prevalence in a previous study.…”

“…Nursing care for UR uses non-invasive methods, such as lukewarm compresses in the suprapubic region, enhancing patients' privacy and offering the sound of running water, so that spontaneous urination can occur. In some cases, aseptic intermittent catheterization is needed, which entails the important need for clinical nursing assessment (1,3,(27)(28) . UTIs have been addresses as one of the main factors of concern among health professionals, representing about 40% of hospital infections, placing an economic burden on services, provoking sequelae, complications and immeasurable patient damage.…”

Fuzzy cognitive map in differential diagnosis of alterations in urinary elimination: A nursing approach

“…There are two types of expert systems previously published by the authors, that make the differential diagnosis of alterations in urinary elimination using NANDA-I nursing terminology [16,17,18]. The first system was based on classical rules and decision-tree structure (ALTURIN.SDD) [16,17], while the second was based on the fuzzy relations [18].…”

“…The first system was based on classical rules and decision-tree structure (ALTURIN.SDD) [16,17], while the second was based on the fuzzy relations [18]. …”

“…ALTURIN.SDD is limited by missing data, which happens when it is not possible to obtain all information from the patient or even to decide with absolute certainty if a signal or symptom is present or not [17]. On the other hand, in the fuzzy relation approach, the interaction between different signs or symptoms was not considered.…”
