ABSTRACT

Neste Atlas da Violência 2023, como realizado nas últimas edições, buscou-se retratar a violência no Brasil principalmente a partir dos dados do Sistema de Informação sobre Mortalidade (SIM) e do Sistema de Informação de Agravos de Notificação (Sinan), do Ministério da Saúde. No entanto, na base de dados do SIM, verificou-se um importante aumento das Mortes Violentas por Causa Indeterminada (MVCI) a partir de 2019, o que prejudica a análise sobre as mortes violentas perpetradas de maneira intencional. Para contornar esse problema, Cerqueira e Lins (2023) produziram dois estudos – que serão divulgados em breve – não apenas avaliando a qualidade desses dados, mas também estimando, por meio de metodologia de machine learning, o número de homicídios erroneamente classificados com MVCI, chamados aqui de "homicídios ocultos". No presente documento, faremos duas análises sobre a prevalência de homicídios nas UFs, considerando apenas os registros oficiais classificados como homicídio (mortes ocasionadas por agressões ou por intervenção legal) e levando em conta ainda a parcela dos homicídios ocultos estimada no trabalho dos autores supramencionados.

ABSTRACT

INTRODUCTION: It is important for clinical laboratories to maintain under control the possible sources of error in its analytical determinations. The objective of this work is to perform an analysis of the total error committed by laboratories using the data extracted from the Spanish External Quality Assessment Program in Hematology and to compare them with the specifications based on the biological variability proposed by the Ricós group. MATERIAL AND METHODS: We analyzed a total of 3 89 000 results during the period 2015-2016 from the following quantitative schemes of Spanish External Quality Assessment Program: complete blood count, blood coagulation tests, differential leukocyte count, reticulocytes, hemoglobin A2 , antithrombin, factor VIII, protein C, and von Willebrand factor. It has been considered as an indicator of the current performance the value of total error that 90% of laboratories are able to achieve, taking into account 75% of their results. RESULTS: We found some magnitudes whose biological variability specifications are achievable by most of the laboratories for either minimum, desirable, or optimum criteria: white blood cells, red blood cells, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, platelets, fibrinogen, neutrophils, lymphocytes, eosinophils, von Willebrand factor, and protein C. However, current performance for mean corpuscular hemoglobin concentration and hemoglobin A2 only allows to meet the specifications based on the state of the art. CONCLUSION: Our results reflect the feasibility of establishing specifications based on biological variability criteria or the state of the art, which may help to select the proper criteria for each parameter.
