Summary: | 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 knowledge with a strong correlation (r=0.96). CONCLUSIONS: The linguistic model was able to estimate the risk of neonatal death when compared to experts' performance.<br>OBJETIVO: Apresentar um modelo linguístico fuzzy para estimar o risco de morte neonatal. MÉTODOS: Baseia-se nas variáveis peso ao nascer e idade gestacional, consideradas como variáveis fuzificadas; a inferência utilizada foi o método de Mamdani; foram entrevistados neonatologistas para estimar o risco de morte neonatal sob determinadas condições de peso e idade gestacional e compararam-se estes valores com aqueles estimados pelo modelo. RESULTADOS: Os resultados do modelo apresentam boa correlação com os valores atribuídos pelos especialistas com r=0,96. CONCLUSÕES: O modelo lingüístico fuzzy proposto apresentou boa concordância quando comparado com as estimativas dos especialistas, para os valores de risco de morte neonatal. |
