Fuzzy linguistic model for evaluating the risk of neonatal death

Abstract: OBJECTIVE: To introduce a fuzzy linguistic model for evaluating the risk of neonatal death. METHODS: The study is based on the fuzziness of the variables newborn birth weight and gestational age at delivery. The inference used was Mamdani's method. Neonatologists were interviewed to estimate the risk of neonatal death under certain conditions and to allow comparing their opinions and the model values. RESULTS: The results were compared with experts' opinions and the Fuzzy model was able to capture the expert k… Show more

“…Constructed on the basis of expert consultation and expertise, the FIS simulates human reasoning to support decisions based on a given condition 23,24 , such as diagnoses and monitoring in the health area 25,26,27,28,29,30,31 . Construction of the FIS thus involves four principal stages: fuzzification, construction of the rules set, inference, and defuzzification 32 .…”

“…5 Também para estimar risco de óbito neonatal, além destes escores citados, foi desenvolvido modelo linguístico utiilizando-se da lógica fuzzy, segundo peso ao nascer e idade gestacional. 6 No Brasil, o escore CRIB está sendo aplicado com resultados que mostram seu valor na predição do óbito neonatal, apontando grupos de recém-nascidos de maior risco; os valores obtidos através do escore CRIB se mostram mais robustos quando comparados com valores obtidos segundo o peso ao nascer e idade gestacional do recém-nascido. [7][8][9] O objetivo deste estudo é apresentar o resultado do escore CRIB aplicado em todos os recém-nascidos, como preditor de óbito neonatal em UTIN, compará-lo com os resultados preditores obtidos do peso ao nascer e idade gestacional e avaliar sua associação com outras variáveis obtidas durante a internação do recém-nascido.…”
