Morbidade materna extremamente grave: uso do sistema de informação hospitalar do SUS

Abstract

An extremely severe maternal morbidity (ESMM) case, or near miss, is one in which the woman almost died due to gestation/delivery-related problems, or any problem occurring up to 42 days after the end of gestation, but survived because of the care received or sheer chance. The criteria for identification of ESMM cases have been discussed by several authors, who take into account clinical and laboratory features and/or case management. Health information systems available in Brazil, such as the Hospital Information System (Sistema de Informações Hospitalares – SIH-SUS), Live-birth Information System (Sistema de Informações sobre Nascidos Vivos – SINASC) and Mortality Information System (Sistema de Informações sobre Mortalidade – SIM) comprise a large number of data, which could contribute to studies on maternal morbidity. This study aimed to: assess maternal and childhood morbimortality from the SIH-SUS, adequate the ESMM criteria, and identify and analyze the ESMM cases within the SIH-SUS database, with a focus on the planning of maternal health interventions. Of the 8620 women living in Juiz de Fora, MG, Brazil, admitted to hospital with a diagnosis belonging to chapter XV of the ICD-10, or who underwent an obstetric procedure, in the period 2006-2007, 326 had a clinical condition and/or procedure selected as ESMM, with 1 death. Maternal mortality rate was 12.0/100,000 women. Case-fatality rate was 3.1/1,000 women, and ESMM rate was 39.0/1,000 women. Mean hospital stay length ranged from 10.5 to 3.5 days, for women with and without ESMM, respectively. Hospital stay length over 4 days was 13 more likely for ESMM women. Prevalence ratios of newborn hospital stay after the mother`s discharge, stillbirth, and child`s death before the mother`s discharge were higher for ESMM women, being 2.52, 4.86, and 4.41, respectively. The variables hospital stay length, number of admissions, and number of stillbirths were predictors of ESMM on logistic regression analysis (p < 0.001). Of the selected procedures/conditions, the most frequent ones were blood derivatives transfusion, longer hospital stay, and severe pre-eclampsia/eclampsia, with specific morbidity prevalence rates of 15.7/1,000, 9.5/1,000 and 8.2/1,000, respectively. The ESMM prevalence ratio found and the specific prevalence rates of blood derivatives transfusion and severe pre-eclampsia/eclampsia are consistent with literature data, and show that the association use of the SIH-SS tables has significant potential to identify ESMM cases. The criterion used for case identification is feasible and may contribute to maternal morbimortality surveillance, increasing our knowledge about its associated features and contributing to better prenatal/puerperal care.
