Sistema de apoio à decisão para a prática da enfermagem baseada em evidências em Unidade de Terapia Intensiva

In the field of nursing research, there is an increase in interest in seeking scientific evidence aimed at solving complex problems in care practice. This model is called Evidence-Based Nursing, its practice takes into account the levels of scientific evidence presented in publications. Due to the amount and complexity of information in the health area, there is a need to produce methods for evaluating scientific evidence and decision support models as tools to aid in the practice of evidence-based nursing, in order to expose different strategies and their respective consequences in terms of risks and benefits for a given clinical issue. Therefore, this study aims to develop a computer-based decision-making model for use in evidence-based nursing practice. It is an exploratory scientific and experimental research, prescriptive with a quantitative approach. The research site was the Intensive Care Unit of the University Hospital Lauro Wanderley, where 77 cases of patients were selected with transcripts of the records of the first 24 hours of admission from the Patient Admission Form, Nursing History, Clinical Evolution and prescriptions on the day of admission by intensive care nurses about the care provided. To define the decision model, the Waika to Environment for Knowledge Analysis (WEKA) software was used, using the Hidden Naive Bayes (HNB) classifier as it presents the best results. In the present study, the HNB is composed of three characteristics of the case bank: identification/vital signs of patients, nursing diagnoses and nursing interventions. These characteristics were used to store the cases in the database and it is through them that interventions for each new case will be sought in this database. This study developed from a new decision support model for evidence-based nursing practice involving Bayesian Networks and a methodological approach to extract information from scientific evidence, constituting a management and decision support tool for nurses called SADEBE. It was observed that there are ...
