Mapas de taxas epidemiológicas: uma abordagem Bayesiana

Abstract: This article presents statistical methods recently developed for the analysis of maps of disease rates when the geographic units have small populations at risk. They adopt the Bayesian approach and use intensive computational methods for estimating risk in each area. The objective of the methods is to separate the variability of rates due to differences between regions from the background risk due to pure random fluctuation. Risk estimates have a total mean quadratic error smaller than usual estimates. We appl… Show more

“…. Most of the authors used the local Bayesian empirical model to smooth the leprosy detection coefficients in an attempt to alleviate random fluctuations in the indicators, a consequence of rare events in small populations 50 . Smoothing of detection rates can improve early detection of cases, increase the number of regions classified as hyperendemic and the number of people needed to be followed to detect one new case of leprosy 39,45 .…”

“…A variabilidade fornecida pelo cálculo de taxas brutas está relacionada ao tamanho da população sob risco e à instabilidade presente no indicador. Além disso, conforme apontado por diversos autores, na análise espacial de informações de saúde, as técnicas de ajustamento bayesianas empíricas são capazes de produzir mapas temáticos com informações mais próximas da realidade de cada região estudada, sendo mais adequadas para análises espaciais do que as técnicas estatísticas clássicas 8,9,15 .…”
