Analysis of Biological Samples Necroscopic Reports from the Death Verification Service of the State of Tocantins, Brazil

Abstract

Analyze, in the necroscopic reports of the Death Verification Service of the State of Tocantins (SVO-TO), the records of biological samples collected for histopathological examination and records of autolysis in histopathological results and correlate them with records of causes of mortality and morbidity. Cross-sectional observational analytical study conducted in 494 autopsy reports completed and filed in SVO-TO, Brazil, between 2012 and 2016. Records of the number of biological samples collected for histopathology, number of autolysis, number of causes of mortality and number of causes of morbidity were extracted and identified. For the analysis of the relationship between the variables, descriptive and analytical statistics were used in SAS SYSTEM software. The mean number of mortality records was 5.72 ± 2.42 (CV 42.32%), causes of morbidity: 0.2 ± 0.5 (CV 251.46%), number of biological samples collected: 2.66 ± 1.13 (CV 42.59%), number of autolysis: 1.74 ± 1.05 (CV 60.06%). The number of mortality and morbidity diagnoses recorded in SVO reports increases the higher the number of samples collected by necropsies physicians. The number of biological samples collected by necropsy positively impacts the number of causes of mortality and morbidity. Collecting more than seven tissue samples by necropsy does not impact the number of causes of mortality and morbidity. The low numbers of autolysis records suggest efficacy in the collection of biological samples in SVO-TO.

Análises e correlações entre resultados histopatológicos, morbidade e mortalidade registrados nos laudos necroscópicos do SVOI de Ribeirão Preto - SP, 2014-2016

“…Nos laudos estudados em Ribeirão Preto foram encontrados 291 registros de amostras coletadas para exame histopatológico, com média de 0,41±1,64, por necropsia, porém o manual sobre "Autópsias da Sociedade Brasileira de Patologia" preconizar que sejam confeccionadas cerca de 40 lâminas para que ocorra uma representação ideal de todos os órgãos (Echenique et al, 2002). No SVO-TO, quando coletadas mais de 7 amostras biológicas para exame histopatológico por necropsia, não há impacto na quantidade de causas de mortalidade registradas nos laudos necroscópicos (Carvalho et al, 2020).…”
