The 11th International Statistical Classification of Diseases and Related Health Problems (ICD-11) represents an advance in the focus on knowledge and new disease approaches. The ICD is used for different practical purposes, enabling assessment of progress in the global health agenda, resource allocation, patient safety, health care qualification, and health insurance reimbursement. It is entirely digital, with technological resources that allow periodic updating. In early 2022, ICD-11 entered into official force, having been made available in several official ICD languages such as Arabic, Chinese, Spanish, French, and English. The translation process into Brazilian Portuguese, coordinated by the Federal University of Minas Gerais (UFMG), with support from the Brazilian Ministry of Health (MS) and PAHO/WHO, is presented here. The work was carried out in three stages between August 2021 and December 2022 by translators with different backgrounds: medical specialists (49), physiotherapists (1), pharmacologists (1), and dentists (1). This methodological article aims to broaden the discussion of perspectives on implementing the ICD-11 in Brazil and build an opportunity for its adaptation and use by other Portuguese-speaking countries.

The covid-19 pandemic and hospital morbidity due to mental and behavioral disorders in Brazil: an interrupted time series analysis, from January 2008 to July 2021.

OBJECTIVE: to analyze records of hospitalizations due to mental and behavioral disorders before and after the beginning of the covid-19 pandemic in Brazil, from January 2008 to July 2021. METHODS: this was a descriptive ecological interrupted time series study, using secondary data retrieved from the Brazilian National Health System Hospital Information System; a time series analysis of hospitalizations was conducted based on a population-weighted Poisson regression model; relative risk (RR) and respective 95% confidence intervals (95%CI) were calculated. RESULTS: we identified 6,329,088 hospitalizations due to mental and behavioral disorders; hospitalization rates showed an 8% decrease (RR = 0.92; 95%CI 0.91;0.92) after the start of the pandemic, compared to the pre-pandemic period. CONCLUSION: the pandemic changed the trend of hospitalizations due to mental and behavioral disorders in Brazil; the drop observed in the period is evidence that the pandemic affected the mental health care network.

Covid-19: temporal evolution and immunization in the three epidemiological waves, Brazil, 2020-2022.

OBJECTIVE: Describe the temporal evolution of morbimortality due to Covid-19 and vaccination coverage during the health emergency in Brazil. METHODS: Number of cases and deaths due to Covid-19 were extracted from the public panel of the Brazilian Ministry of Health, according to epidemiological week (EW) and geographic region. Data on vaccines and variants were obtained, respectively, from the Information System of the National Immunization Program and the Genomic Surveillance System of SARS-CoV-2. RESULTS: Three peaks of deaths characterized the evolution of the Covid-19 pandemic: in EW 30 of 2020, in the EW 14 of 2021 and in the EW six of 2022; three case waves, starting in the North and Northeast regions, with higher rates in the third wave, mainly in the South region. Vaccination started in the epidemiological week three of 2021, rapidly reaching most of the population, particularly in the Southeast and South regions, coinciding with a reduction exclusively in the mortality rate in the third wave. Only from the beginning of the second wave, when Gama was the dominant variant, 146,718 genomes were sequenced. From the last EW of 2021, with vaccination coverage already approaching 70%, the Omicron variant caused an avalanche of cases, but with fewer deaths. CONCLUSIONS: We noticed the presence of three waves of Covid-19, as well as the effect of immunization on the reduction of mortality in the second and third waves, attributed to the Delta and Omicron variants, respectively. However, the reduction of morbidity, which peaked in the third wave during the domination of the Omicron variant, remained the same. The national and centralized command of the pandemic confrontation did not occur; thus, public administrators took the lead in their territories. The overwhelming effect of the pandemic could have been minimized, if there had been a coordinated participation of three spheres of the Brazilian Unified Health System administration, in the joint governance of the pandemic fight.

Objective: To present the experience and results of the reregistration of residents in Foz do Iguaçu, a border town located in the state of Paraná, Brazil, to meet the guidelines of the national Primary Health Care (PHC) Policy and its new financing model (Programa Previne Brasil). Method: A scanning strategy (convenience sample) was used for data collection, with 52 263 households visited and 22 710 interviews conducted from September to November 2019. The interviews were conducted face-to-face by 54 community health workers. Data were collected on the household (ownership status, urban or rural location, type of household, construction material, availability of electrical and sewage networks, water supply and waste disposal). Demographic and health information on the residents was also collected. Results: The reregistration process revealed that most residents were home owners and lived in well-constructed homes, located mostly in urban areas, served by electricity, with access to water supply and garbage collection. Of the reregistered population, 52.8% were women, 62.5% were aged between 15 and 59 years and 60.0% declared themselves white. Among respondents aged 15 or over, 90.0% had completed elementary school. The main occupation was "formal salaried job". Additionally, 18.6% of the interviewees declared themselves to be hypertensive and 7.0%, diabetic. Conclusions: The reregistration process uncovered relevant information to support both PHC planning as well as social assistance, work and housing initiatives; it was also fundamental to define health care strategies in this border town during the COVID-19 pandemic.

Mortality in children under five years old in Brazil: evolution from 2017 to 2020 and the influence of COVID-19 in 2020

Abstract Objective: To analyse the mortality trends in children under five years old in Brazil from 2017 to 2020 and the influence of COVID-19 in 2020. Methods: A retrospective study employing secondary data from the Brazilian Mortality Information System. Deaths according to cause were extracted and disaggregated into early, late, post-neonatal, and 1 to 4-year-old periods. Corrected mortality rates per 1, 000 live births and relative risk ratio for the cause of death were calculated. Results: There were 34, 070 deaths, being 417 (1.2%) from COVID-19 in 2020. COVID-19 mortality was 0.17 per 1000 live births, reaching 0.006 in the early neonatal period, 0.007 in the late neonatal, 0.09 in the postneonatal, and 0.06 in 1 to 4-year-old. Mortality decreased mostly for some diseases that originated in the perinatal period, congenital anomalies, diseases of the respiratory system and external causes, in this order. In 2020, the highest rate was in the early neonatal period, with a fall from 7.2 to 6.5, followed by the postneonatal (3.9 to 3.4) and late neonatal (2.3 to 2.1). Among children aged 1 to 4-year-old, external causes had the highest proportional rate, and diseases of the respiratory system showed the highest decline. Conclusion: The mortality rate declined from 2017 to 2020, and this variation was higher in the early neonatal period. The risk of death from COVID-19 was 14 times higher in the postneonatal period and 10 times higher in children aged 1 to 4 year-old compared to the early neonatal period.

Physicians' Perceptions as Predictors of the Future Use of the National Death Information System in Peru: Cross-sectional Study.

BACKGROUND: A computer application called the National Death Information System (SINADEF) was implemented in Peru so that physicians can prepare death certificates in electronic format and the information is available online. In 2018, only half of the estimated deaths in Peru were certified using SINADEF. When a death is certified in paper format, the probability being entered in the mortality database decreases. It is important to know, from the user's perspective, the factors that can influence the successful implementation of SINADEF. SINADEF can only be successfully implemented if it is known whether physicians believe that it is useful and easy to operate. OBJECTIVE: The aim of this study was to identify the perceptions of physicians and other factors as predictors of their behavioral intention to use SINADEF to certify a death. METHODS: This study had an observational, cross-sectional design. A survey was provided to physicians working in Peru, who used SINADEF to certify a death for a period of 12 months, starting in November 2019. A questionnaire was adapted based on the Technology Acceptance Model. The questions measured the dimensions of subjective norm, image, job relevance, output quality, demonstrability of results, perceived usefulness, perceived ease of use, and behavioral intention to use. Chi-square and logistic regression tests were used in the analysis, and a confidence level of 95% was chosen to support a significant association. RESULTS: In this study, 272 physicians responded to the survey; 184 (67.6%) were men and the average age was 45.3 (SD 10.1) years. The age range was 24 to 73 years. In the bivariate analysis, the intention to use SINADEF was found to be associated with (1) perceived usefulness, expressed as "using SINADEF avoids falsifying a death certificate" (P<.001), "using SINADEF reduces the risk of errors" (P<.001), and "using SINADEF allows for filling out a certificate in less time" (P<.001); and (2) perceived ease of use, expressed as "I think SINADEF is easy to use" (P<.001). In the logistic regression, perceived usefulness (odds ratio [OR] 8.5, 95% CI 2.2-32.3; P=.002), perceived ease of use (OR 10.1, 95% CI 2.4-41.8; P=.001), and training in filling out death certificates (OR 8.3, 95% CI 1.6-42.8; P=.01) were found to be predictors of the behavioral intention to use SINADEF. CONCLUSIONS: The behavioral intention to use SINADEF was related to the perception that it is an easy-to-use system, the belief that it improves the performance of physicians in carrying out the task at hand, and with training in filling out death certificates.

Covid-19: temporal evolution and immunization in the three epidemiological waves, Brazil, 2020-2022 / Covid-19: evolução temporal e imunização nas três ondas epidemiológicas, Brasil, 2020-2022

ABSTRACT OBJECTIVE Describe the temporal evolution of morbimortality due to Covid-19 and vaccination coverage during the health emergency in Brazil. METHODS Number of cases and deaths due to Covid-19 were extracted from the public panel of the Brazilian Ministry of Health, according to epidemiological week (EW) and geographic region. Data on vaccines and variants were obtained, respectively, from the Information System of the National Immunization Program and the Genomic Surveillance System of SARS-CoV-2. RESULTS Three peaks of deaths characterized the evolution of the Covid-19 pandemic: in EW 30 of 2020, in the EW 14 of 2021 and in the EW six of 2022; three case waves, starting in the North and Northeast regions, with higher rates in the third wave, mainly in the South region. Vaccination started in the epidemiological week three of 2021, rapidly reaching most of the population, particularly in the Southeast and South regions, coinciding with a reduction exclusively in the mortality rate in the third wave. Only from the beginning of the second wave, when Gama was the dominant variant, 146,718 genomes were sequenced. From the last EW of 2021, with vaccination coverage already approaching 70%, the Omicron variant caused an avalanche of cases, but with fewer deaths. CONCLUSIONS We noticed the presence of three waves of Covid-19, as well as the effect of immunization on the reduction of mortality in the second and third waves, attributed to the Delta and Omicron variants, respectively. However, the reduction of morbidity, which peaked in the third wave during the domination of the Omicron variant, remained the same. The national and centralized command of the pandemic confrontation did not occur; thus, public administrators took the lead in their territories. The overwhelming effect of the pandemic could have been minimized, if there had been a coordinated participation of three spheres of the Brazilian Unified Health System administration, in the joint governance of the pandemic fight.

RESUMO OBJETIVO Descrever a evolução temporal da morbimortalidade por covid-19 e da cobertura vacinal no período da emergência sanitária no Brasil. MÉTODOS Número de casos e óbitos por covid-19 foram extraídos do painel público do Ministério da Saúde, conforme semana epidemiológica (SE) e região geográfica. Dados sobre vacinas e variantes foram obtidos, respectivamente, do Sistema de Informação do Programa Nacional de Imunizações e do Sistema de Vigilância Genômica do SARS-CoV-2. RESULTADOS A evolução da pandemia de covid-19 caracterizou-se por três picos de óbitos: na 30ᵃ semana epidemiológica de 2020, na 14ᵃ de 2021 e na sexta de 2022; três ondas de casos, iniciando-se nas regiões Norte e Nordeste, com maiores taxas na terceira onda, principalmente na região Sul. A vacinação teve início na terceira semana epidemiológica de 2021, atingindo rapidamente a maior parte da população, particularmente nas regiões Sudeste e Sul, coincidindo com redução da taxa de mortalidade, mas não de morbidade na terceira onda. No total, 146.718 genomas foram sequenciados, mas somente a partir do início da segunda onda, na qual a variante dominante foi a Gama. A partir da última SE de 2021, quando a cobertura vacinal já se aproximava de 70%, a variante Ômicron causou uma avalanche de casos, porém com menos óbitos. CONCLUSÕES É nítida a presença de três ondas de covid-19, bem como o efeito da imunização na redução da mortalidade na segunda e na terceira ondas, atribuídas às variantes Delta e Ômicron, respectivamente. Contudo não houve efeito na redução da morbidade, que atingiu o pico na terceira onda, na qual dominou a variante Ômicron. O comando nacional e centralizado do enfrentamento à pandemia não ocorreu; assim, os gestores locais assumiram a liderança em seus territórios. O efeito avassalador da pandemia poderia ter sido minimizado, caso houvesse a participação coordenada das três esferas de governo no SUS.

Restructuring of emergency services to COVID-19 in Brazil: a space-time analysis from February to August 2020. / Reestruturação dos serviços de emergência à COVID-19 no Brasil: uma análise espaço-temporal, fevereiro a agosto de 2020.

OBJECTIVE: To explore the reorganization of the health system in response to the COVID-19 pandemic. METHODS: We conducted an ecological, descriptive-exploratory study with analysis of spatio-temporal clusters by epidemiological week in Brazilian municipalities. Secondary data sources were used, from the National Health Establishment Registry (April 2020) and on COVID-19 cases, February to August 2020. Intensive Care Units (ICU) availability was overlaid on incidence and mortality hot spots in order to assess expanded access in critical regions. RESULTS: Of the 5,570 municipalities analyzed, 54% were identified as incidence hot spots and 31% as mortality hot spots. Of the municipalities in incidence hot spots and with scarce access, 28% were covered by ICU expansion, while with regard to mortality 14% were covered. CONCLUSION: The opening of new beds was not able to provide broad coverage for critical regions and could be optimized with the use of spatial analysis techniques.

COVID-19 as the leading cause of hospital deaths in the Brazilian public health system in 2020.

OBJECTIVES: To describe the profile of hospital deaths in Brazil according to cause of admission during the pre-pandemic (2019) and pandemic periods (2020). METHODS: Descriptive study based on individual-level records of all hospital admissions with death outcomes reimbursed by the Brazilian National Health System in 2019 and 2020. RESULTS: The number of hospital deaths increased by 16.7% in 2020 compared with 2019 (522,686 vs 609,755). Coronavirus disease 2019 (COVID-19) was associated with 19.5% (118,879) of all hospital deaths in 2020, surpassing diseases of the circulatory system (15.4%, 93,735) and diseases of the respiratory system (14.9%, 91,035). CONCLUSIONS: COVID-19 was the main cause of death in public hospitals in Brazil in 2020.

Clinical profile and mortality in patients with T. cruzi/HIV co-infection from the multicenter data base of the "Network for healthcare and study of Trypanosoma cruzi/HIV co-infection and other immunosuppression conditions".

OBJECTIVE: Chagas disease (CD) globalization facilitated the co-infection with Human Immunodeficiency Virus (HIV) in endemic and non-endemic areas. Considering the underestimation of Trypanosoma cruzi (T. cruzi)-HIV co-infection and the risk of life-threatening Chagas Disease Reactivation (CDR), this study aimed to analyze the major co-infection clinical characteristics and its mortality rates. METHODS: This is a cross-sectional retrospective multicenter study of patients with CD confirmed by two serological or one parasitological tests, and HIV infection confirmed by immunoblot. CDR was diagnosed by direct microscopy with detection of trypomastigote forms in the blood or other biological fluids and/or amastigote forms in inflammatory lesions. RESULTS: Out of 241 patients with co-infection, 86.7% were from Brazil, 47.5% had <200 CD4+ T cells/µL and median viral load was 17,000 copies/µL. Sixty CDR cases were observed. Death was more frequent in patients with reactivation and was mainly caused by CDR. Other causes of death unrelated to CDR were the manifestation of opportunistic infections in those with Acquired Immunodeficiency Syndrome. The time between the co-infection diagnosis to death was shorter in patients with CDR. Lower CD4+ cells count at co-infection diagnosis was independently associated with reactivation. Similarly, lower CD4+ cells numbers at co-infection diagnosis and male sex were associated with higher lethality in CDR. Additionally, CD4+ cells were lower in meningoencephalitis than in myocarditis and milder forms. CONCLUSION: This study showed major features on T. cruzi-HIV co-infection and highlighted the prognostic role of CD4+ cells for reactivation and mortality. Since lethality was high in meningoencephalitis and all untreated patients died shortly after the diagnosis, early diagnosis, immediate antiparasitic treatment, patient follow-up and epidemiological surveillance are essentials in T. cruzi/HIV co-infection and CDR managements.

Objetivo: Explorar a reorganização do sistema de saúde voltado para a pandemia de COVID-19. Métodos: Realizou-se estudo ecológico, descritivo-explicativo, com análise de aglomerados espaço-temporais por semana epidemiológica nos municípios brasileiros. Foram utilizadas fontes de dados secundárias, do Cadastro Nacional de Estabelecimentos de Saúde (abril de 2020) e de casos de COVID-19 (fevereiro a agosto de 2020). As áreas quentes de incidência e mortalidade foram sobrepostas com a disponibilidade de unidades de tratamento intensivo (UTIs), para se avaliar a ampliação do acesso em regiões críticas. Resultados: Dos 5.570 municípios analisados, 54% foram identificados como áreas quentes para incidência e 31% para mortalidade. Dos municípios em áreas quentes para incidência e com escassez de acesso, 28% foram contemplados pela ampliação de UTIs. Para mortalidade, esse valor foi de 14%. Conclusão: A abertura de novos leitos não conseguiu abranger amplamente as regiões críticas, entretanto poderia ser otimizada com o uso de técnicas de análise espacial.

Data for health: impact on improving the quality of cause-of-death information in Brazil. / Dados para a saúde: impacto na melhoria da qualidade da informação sobre causas de óbito no Brasil.

INTRODUCTION: Knowing the number of deaths and their causes is relevant information for public health managers. However, the cause of death is often classified with codes that are not useful for mortality analysis, called garbage codes (GC). OBJECTIVE: To describe and evaluate the impact of investigation of the underlying cause of poorly classified deaths on death certificates in 2017. METHODS: Based on a standardized protocol, GC deaths from 60 municipalities were investigated, mainly in hospital records and autopsy services. Managers at the state level of the Mortality Information System also developed procedures to improve the classification of causes of death, with the consequent adherence of other municipalities (n = 4022). This made it possible to compare the results of GC research between these two groups of municipalities. RESULTS: In the country, among the 108,826 GC investigated in 2017, 48% were reclassified to specific causes. In the 60 focus municipalities, 58% of the 35,366 investigated deaths from GC were reclassified. After the intervention, the proportion of deaths classified as GC decreased by 11% in the country and 17% in the municipalities. DISCUSSION: The research in hospital records enabled almost half of the deaths from GC investigated to be reclassified. This is the first study to investigate GC in hospital records of more than 100,000 deaths. The 60 cities targeted by the intervention had better results than the other cities. CONCLUSION: The intervention proved to be an appropriate initiative to improve the quality of information on cause of death and should be encouraged.

INTRODUÇÃO: Conhecer o número de óbitos e suas causas se constitui em informação de relevância para gestores de saúde pública. Entretanto, muitas vezes a causa do óbito é classificada com códigos pouco úteis para as análises de mortalidade, denominados códigos garbage (CG). OBJETIVO: Descrever e avaliar o impacto da investigação da causa básica de morte mal classificada no atestado de óbito em 2017. MÉTODOS: Com base em protocolo padronizado, foram pesquisadas mortes com CG de 60 municípios que foram foco da intervenção, principalmente em prontuários hospitalares e serviços de autopsia. No nível estadual de gestão do Sistema de Informação de Mortalidade também foram desenvolvidas ações para melhoria da classificação da causa do óbito, com consequente adesão da maioria dos demais municípios (n = 4.022), o que permitiu comparações com os resultados da investigação de CG nas 60 cidades. RESULTADOS: No país, de 108.826 CG investigadas em 2017, 48% foram reclassificadas para causas específicas. Já nos 60 municípios selecionados, 58% dos 35.366 óbitos por CG pesquisados foram reclassificados. A proporção de óbitos por CG declinou em 11% no país e 17% nos municípios em que houve intervenção. DISCUSSÃO: Este é o primeiro estudo que investigou CG em registros médicos de mais de 100 mil mortes. A pesquisa possibilitou reclassificar para causas básicas específicas cerca de metade dos óbitos por CG investigados. As 60 cidades que foram alvo da intervenção tiveram melhor resultado que as demais cidades. CONCLUSÃO: A intervenção mostrou ser uma iniciativa adequada para a melhoria da qualidade da informação sobre causa de morte e deve ser estimulada.

Mortality on the first day of life: trends, causes of death and avoidability in eight Brazilian Federative Units, between 2010 and 2015. / Mortalidade no primeiro dia de vida: tendências, causas de óbito e evitabilidade em oito Unidades da Federação brasileira, entre 2010 e 2015.

OBJECTIVE: to calculate mortality rates on the first day of life from 2010 to 2015 in eight Brazilian Federative Units providing better quality information, to assess associated factors and to classify deaths by underlying causes and avoidability. METHODS: this was a descriptive study; mortality rates were compared according to maternal and child characteristics; avoidability analysis used the 'Brazilian list of avoidable causes of death'. RESULTS: 21.6% (n=20,791) of all infant deaths occurred on the first day of life; the mortality rate reduced from 2.7 to 2.3 deaths/1,000 live births; rates were higher in live births with low birthweight and preterm births, and among babies born to mothers with no schooling; main causes of death were respiratory distress syndrome (8.9%) and extreme immaturity (5.2%); 66.3% of causes of death were avoidable. CONCLUSION: 2/3 of deaths on the first day of life could have been avoided with adequate care for women during pregnancy and delivery and adequate care for live births.
