Abstract

Cases of maternal near miss are those in which women survive severe maternal complications during pregnancy or the puerperium. This ecological study aimed to identify the temporal trend of near-miss cases in different regions of Brazil between 2010 and 2018, using data from the Hospital Information System (HIS) of the Unified Brazilian Health System (SUS, in the Portuguese acronym). Hospital admission records of women between 10 and 49 years old with diagnosis included in the 10th Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and codes indicating near-miss events were selected. From 20,891,040 admissions due to obstetric causes, 766,249 (3.66%) near-miss cases were identified, and 31,475 women needed admission to the intensive care unit (ICU). The cases were found to be more predominant in black women over 35 years old from the North and Northeast regions. There was a trend of increase in near-miss rates of ∼ 13.5% a year during the period of the study. The trend presented a different behavior depending on the level of development of the region studied. The main causes of near miss were preeclampsia (47%), hemorrhage (24%), and sepsis (18%).

Casos de near miss materna são aqueles em que as mulheres sobrevivem a graves complicações maternas durante a gravidez ou o puerpério. Este estudo ecológico teve como objetivo identificar a tendência temporal de casos de near miss em diferentes regiões do Brasil entre 2010 e 2018, utilizando dados do Sistema de Informações Hospitalares (SIH) do Sistema Único de Saúde (SUS). Foram selecionados registros de internação de mulheres entre 10 e 49 anos com diagnóstico incluído na 10ª revisão da Classificação Internacional de Doenças e Problemas Relacionados à Saúde (CID-10) e códigos indicando eventos de near miss. Das 20.891.040 internações por causas obstétricas, 766.249 (3,66%) casos de near miss foram identificados, e 31.475 mulheres necessitaram de internação na unidade de terapia intensive (UTI). Constatou-se que os casos são mais predominantes em mulheres negras com mais de 35 anos da região Norte e Nordeste. Houve uma tendência de aumento nas taxas de near miss de aproximadamente 13,5% ao ano durante o período do estudo. A tendência apresentou um comportamento diferente, dependendo do nível de desenvolvimento da região estudada. As principais causas de near miss foram pré-eclâmpsia (47%), hemorragia (24%), e sepse (18%).
