Factors associated with post-mortem notification of tuberculosis cases in Brazil, 2014. / Fatores associados à notificação pós-óbito de casos de tuberculose no Brasil, 2014.

According to the World Health Organization (WHO), 1.6 million deaths and 10.6 million cases of tuberculosis (TB) were reported worldwide in 2021. If treated opportunely with the recommended therapy, 85% of patients with TB are healed. The occurrence of death from TB without prior notification of the disease indicates failure in the timely access to this effective treatment. Therefore, this study aimed to identify TB cases with post-mortem notification in Brazil. This is a nested case-control study using a cohort of new TB cases reported to the Braziliam Information System for Notificable Diseases (SINAN). This study analyzed the following variables: selected characteristics of the individual (gender, age, race/color, education), the municipality (Municipality Human Development Index - M-HDI, poverty rate, size, region, and municipality), health services, and underlying or associated cause of death. Logistic regression was estimated using a hierarchical analysis model. People with TB aged 60 years or older (OR = 1.43), with low educational level (OR = 1.67), and with malnutrition (OR = 5.54), living in municipalities with low M-HDI and medium population size (OR = 1.26), located in the North Region of Brazil (OR = 2.42) had a higher chance of post-mortem notification. Protective factors were HIV-TB coinfection (OR = 0.75), malignant neoplasms (OR = 0.62), and living in cities with broad primary care coverage (OR = 0.79). Vulnerable populations should be prioritized in order to address the obstacles to the access to TB diagnosis and treatment in Brazil.

Segundo a Organização Mundial da Saúde (OMS), estima-se que 1,6 milhão de mortes e 10,6 milhões de casos de tuberculose (TB) ocorreram no mundo em 2021. Quando a doença é oportunamente tratada com o esquema terapêutico recomendado, 85% dos pacientes se curam. A ocorrência de óbito por TB sem notificação anterior denuncia falhas no acesso ao tratamento oportuno e efetivo. Sendo assim, este estudo objetivou caracterizar os casos de TB notificados pós-óbito no Brasil. Trata-se de estudo caso-controle aninhado na coorte de casos novos de TB notificados ao Sistema de Informação de Agravos de Notificação (SINAN). As variáveis analisadas foram: características selecionadas do indivíduo (sexo, idade, raça/cor, escolaridade), do município (Índice de Desenvolvimento Humano Municipal - IDH-M, taxa de pobreza, porte municipal, região e município), dos serviços de saúde e causa básica ou associada de morte. Foi estimada regressão logística respeitando um modelo de análise hierárquico. Pessoas com TB de 60 anos de idade ou mais (OR = 1,43), de baixa escolaridade (OR = 1,67), com desnutrição (OR = 5,54), residentes em municípios com baixo IDH-M, de porte populacional médio (OR = 1,26), na Região Norte (OR = 2,42) apresentaram maior chance de notificação pós-óbito. Fatores protetores foram coinfecção HIV-TB (OR = 0,75), neoplasias malignas (OR = 0,62) e residência em municípios com alta cobertura de atenção básica (OR = 0,79). A priorização das populações vulneráveis é necessária para enfrentar as dificuldades de acesso ao diagnóstico e tratamento da TB no Brasil.

La Organización Mundial de la Salud (OMS) estima que en 2021 se produjeron 1,6 millones de muertes por tuberculosis (TB) y 10,6 millones de casos de esta afección por todo el mundo. Si los pacientes siguen el tratamiento recomendado para la TB, un 85% logran la cura. Las muertes por TB sin notificación previa de caso indican fallas en el acceso a este tratamiento oportuno y efectivo. Por lo tanto, este estudio tuvo como objetivo caracterizar los casos de TB que tuvieron notificación posterior a la muerte en Brasil. Este es un estudio de caso-control anidado dentro de la cohorte de nuevos casos de TB informados al Sistema de Información de Enfermedades de Notificación Obligatoria (SINAN). Las siguientes variables fueron analizadas: características seleccionadas del individuo (sexo, edad, etnia/color, nivel de instrucción) y del municipio (Índice de Desarrollo Humano Municipal -IDH-M, tasa de pobreza, tamaño del municipio, región y municipio), servicios de salud y condiciones y causa de la muerte o su asociación. La regresión logística se estimó desde un modelo de análisis jerárquico. Las personas con TB de 60 años o más (OR = 1,43), con bajo nivel de instrucción (OR = 1,67), con desnutrición (OR = 5,54), residentes en municipios con bajo IDH-M, de tamaño poblacional medio (OR = 1,26) y en la Región Norte (OR = 2,42) tuvieron mayor probabilidad de notificación posterior a la muerte. Los factores protectores fueron la coinfección VIH-TB (OR = 0,75), neoplasias malignas (OR = 0,62) y vivir en ciudades con alta cobertura de atención primaria (OR = 0,79). Es necesario priorizar las poblaciones vulnerables para enfrentar las dificultades de acceso al diagnóstico y tratamiento de la TB en Brasil.

Unexpected slowdown in the decline of tuberculosis mortality rates in Brazil from 1997 to 2017: an ecological study.

BACKGROUND: Brazil is a signatory to the World Health Organization End TB Strategy and the United Nations Sustainable Development Goals. This study aims to characterize tuberculosis (TB) deaths and TB mortality rates in Brazil for the period 1997-2017. METHODS: We performed an ecological study based on information for TB deaths between 1997 and 2017 extracted from the Mortality Information System of the Brazilian Ministry of Health. Data included gender, age group and geographic regions. The trends in mortality rates were estimated using Joinpoint regression analysis, which identifies years in which there is a change in slope of the time series by the Monte Carlo permutation. RESULTS: Between 1997 and 2017 there were 104 172 recorded TB deaths in Brazil and the mortality rates were higher for men and the elderly. The age-adjusted mortality rate decreased from 4.2 per 100 000 in 1997 to 3.0 per 100 000 in 2003 to 2.0 per 100 000 in 2017. The average percentage reduction from 1997 to 2003 was 6.2% (95% confidence interval [CI] -7.7 to -4.7) per year, while from 2003 to 2017 it was 3.0% (95% CI -3.4 to -2.5) per year, representing a slowdown in the rate of decline. CONCLUSION: The high number of deaths and the slowdown in the decline of mortality rates from TB in Brazil maintain the disease as an important public health concern and an obstacle to reaching goals set by international commitments.

Bayesian evidence synthesis to estimate subnational TB incidence: An application in Brazil.

BACKGROUND: Evidence on local disease burden and the completeness of case detection represent important information for TB control programs. We present a new method for estimating subnational TB incidence and the fraction of individuals with incident TB who are diagnosed and treated in Brazil. METHODS: We compiled data on TB notifications and TB-related mortality in Brazil and specified an analytic model approximating incidence as the number of individuals exiting untreated active disease (sum of treatment initiation, death before treatment, and self-cure). We employed a Bayesian inference approach to synthesize data and adjust for known sources of bias. We estimated TB incidence and the fraction of cases treated, for each Brazilian state and the Federal District over 2008-2017. FINDINGS: For 2017, TB incidence was estimated as 41.5 (95 % interval: 40.7, 42.5) per 100 000 nationally, and ranged from 11.7-88.3 per 100 000 across states. The fraction of cases treated was estimated as 91.9 % (89.6 %, 93.7 %) nationally and ranged 86.0 %-94.8 % across states, with an estimated 6.9 (5.3, 9.2) thousand cases going untreated in 2017. Over 2008-2017, incidence declined at an average annual rate of 1.4 % (1.1 %, 1.9 %) nationally, and -1.1%-4.2 % across states. Over this period there was a 0.5 % (0.2 %, 0.9 %) average annual increase in the fraction of incident TB cases treated. INTERPRETATION: Time-series estimates of TB burden and the fraction of cases treated can be derived from routinely-collected data and used to understand variation in TB outcomes and trends.

Trends in Untreated Tuberculosis in Large Municipalities, Brazil, 2008-2017.

We adapted a mathematical modeling approach to estimate tuberculosis (TB) incidence and fraction treated for 101 municipalities of Brazil during 2008-2017. We found the average TB incidence rate decreased annually (0.95%), and fraction treated increased (0.30%). We estimated that 9% of persons with TB did not receive treatment in 2017.

COVID-19 epidemic in Brazil: Where are we at?

OBJETIVE: To analyze the trends of COVID-19 in Brazil in 2020 by Federal Units (FU). METHOD: Ecological time-series based on cumulative confirmed cases of COVID-19 from March 11 to May 12. Joinpoint regression models were applied to identify points of inflection in COVID-19 trends, considering the days since the 50th confirmed case as time unit. RESULTS: Brazil reached its 50th confirmed case of COVID-19 in 11 March 2020 and, 63 days after that, on May 12, 177,589 cases had been confirmed. The trends for all regions and FU are upward. In the last segment, from the 31st to the 63rd day, Brazil presented a daily percentage change (DPC) of 7.3% (95%CI= 7.2;7.5). For the country the average daily percentage change (ADPC) was 14.2% (95%CI: 13.8;14.5). The highest ADPC values were found in the North, Northeast and Southeast regions. CONCLUSIONS: In summary, our results show that all FUs in Brazil present upward trends of COVID-19. In some FUs, the slowdown in DPC in the last segment must be considered with caution. Each FU is at a different stage of the pandemic and, therefore, non-pharmacological measures should be adopted accordingly.

[Gaps in drug-resistant tuberculosis surveillance: probabilistic database linkage in Brazil]. / Lacunas na vigilância da tuberculose drogarresistente: relacionando sistemas de informação do Brasil.

The study aimed to assess the coverage and reliability of drug-resistant tuberculosis (DR-TB) case closure in the Information System on Special Treatments for Tuberculosis (SITE-TB in Portuguese) in Brazil from 2013 to 2016, based on probabilistic linkage with the Information System on Diseases of Notification (SINAN), Laboratory Environment Manager (GAL), and Mortality Information System (SIM). The study population consisted of DR-TB cases that initiated treatment from 2013 to 2016 in Brazil. Linkage with SINAN assessed the coverage and estimated underreporting of DR-TB cases. The capture-recapture method was applied, using the Chapman estimator. Linkage with GAL identified cases diagnosed by the laboratory that had not been reported to SITE-TB. Linkage with SIM assessed the reliability of case closure by death in SITE-TB, using the kappa coefficient. We estimated a population of 2,945 (95%CI: 2,365-3,602) new cases of DR-TB with the Chapman estimator. We located 1,626 individuals in the GAL database that had not been reported to SITE-TB, even with laboratory confirmation of drug resistance. PABAK (prevalance and bias adjusted kappa) of 0.86 (95%CI: 0.85-0.87) was classified as excellent for the agreement in death as the outcome between the SITE-TB and SIM databases. The results pointed to persistent gaps related to diagnosis and treatment of DR-TB in Brazil. Underreporting of DR-TB cases in the SITE-TB database poses a challenge for TB control. Identification of these individuals and early start of treatment should be prioritized in health services.

Evaluation of the Drug-Resistant Tuberculosis Surveillance System, Brazil, 2013-2017. / Avaliação do Sistema de Vigilância da Tuberculose Drogarresistente, Brasil, 2013-2017.

OBJECTIVE: to evaluate the Brazilian Drug-Resistant Tuberculosis Surveillance System (DRTB-SS). METHODS: this was an evaluative study, following Centers for Disease Control and Prevention guidelines, using national data from the Special Tuberculosis Treatment Information System (SITETB), and the Notifiable Diseases Information System (SINAN), from 2013 to 2017. RESULTS: average data completeness was 95% (schooling [89.1%; 5,417/6,078], nationality [94.7%; 5,754/6,078], race/skin color [99.1%; 6,023/6,078], type of resistance [98.6%; 5,995/6,078], clinical form [100%; 6,078/6,078], and HIV test [87%; 5,289/6,078]); average proportion of cases with sputum cultures performed was 65.7% (culture 1 [94.8%; 5,764/6,078], culture 2 [69.8%; 4,241/6,078], culture 3 [54.7%, 3,324/6,078], and culture 4 [43.6%; 2,652/6,078]); DRTB-SS reported 52% (1,197/2,300) of multi-resistant cases estimated by the World Health Organization in 2015, 41.3% (990/2,400) in 2016, and 45.8% (1,100/2,400) in 2017. CONCLUSION: low DRTB-SS sensitivity suggests the need for improved access to DRTB diagnosis.

[Use of database linkage and scripting rules to upgrade variables in the Sinan-TB database]. / Uso de linkage entre diferentes bases de dados para qualificação de variáveis do Sinan-TB e a partir de regras de scripting.

Brazil's Information System on Diseases of Notification (Sinan) is the main tool used by tuberculosis (TB) control programs to assess control measures and TB incidence. This requires data from the system that are reliable and accurate, among other features. The study thus aimed to upgrade the entry variables, condition at closure, HIV testing, AIDS-related illness, and diabetes. Linkage was performed between the Sinan-TB database, the Mortality Information System (SIM), and the single AIDS database for the city of Rio de Janeiro, Brazil. Criteria for upgrading the variables were based on technical materials on TB and the Sinan database and were implemented in a script in Structured Query Language (SQL). There was a 115% increase in treatment dropout due to the decrease in transfers, records without closure, and patients closed due to cure in less than 150 days. There was a 2.4% increase in records with diseases associated with diabetes in the affirmative category after using data from the SIM. For the variables HIV testing and AIDS-associated illness, the increases were 5.3% and 8.7%, respectively, when the information in the AIDS database was considered. In conclusion, upgrading the Sinan-TB database through integration with other information systems improved the data's quality for decision-making on TB control.

[Brazilian National Registry of Healthcare Establishments as a tool for the analysis of decentralization of tuberculosis treatment to basic care services]. / Cadastro Nacional de Estabelecimentos de Saúde como ferramenta de análise da descentralização do atendimento da tuberculose para a atenção básica.

This study aimed to validate a method for classification of healthcare services in Brazil (basic care vs. other levels) and describe the decentralization of tuberculosis (TB) care to basic services (2002 to 2016). The healthcare services that reported and followed TB cases were classified as either "basic care" or "other levels" based on the type of establishment registered in the Brazilian National Registry of Healthcare Establishments (CNES, in Portuguese). The study estimated the agreement between this classification with a previous classification performed in 2013 by Brazil's state and local tuberculosis programs. Using the CNES registry, the authors then calculated the percentage of TB patients treated in basic care from 2002 to 2016. Agreement was 94.4%, and overall kappa index was 0.86. There was a relative increment of 31.2% in TB care provided by basic services (from 50.9% in 2002 to 66.8% in 2016). All regions of Brazil showed an increase in this percentage, except the South. The classification based on the CNES registry allowed analyzing the trend in decentralization of TB treatment to basic healthcare services in Brazil.

Identifying socioeconomic, epidemiological and operational scenarios for tuberculosis control in Brazil: an ecological study.

OBJECTIVES: To identify scenarios based on socioeconomic, epidemiological and operational healthcare factors associated with tuberculosis incidence in Brazil. DESIGN: Ecological study. SETTINGS: The study was based on new patients with tuberculosis and epidemiological/operational variables of the disease from the Brazilian National Information System for Notifiable Diseases and the Mortality Information System. We also analysed socioeconomic and demographic variables. PARTICIPANTS: The units of analysis were the Brazilian municipalities, which in 2015 numbered 5570 but 5 were excluded due to the absence of socioeconomic information. PRIMARY OUTCOME: Tuberculosis incidence rate in 2015. DATA ANALYSIS: We evaluated as independent variables the socioeconomic (2010), epidemiological and operational healthcare indicators of tuberculosis (2014 or 2015) using negative binomial regression. Municipalities were clustered by the k-means method considering the variables identified in multiple regression models. RESULTS: We identified two clusters according to socioeconomic variables associated with the tuberculosis incidence rate (unemployment rate and household crowding): a higher socioeconomic scenario (n=3482 municipalities) with a mean tuberculosis incidence rate of 16.3/100 000 population and a lower socioeconomic scenario (2083 municipalities) with a mean tuberculosis incidence rate of 22.1/100 000 population. In a second stage of clusterisation, we defined four subgroups in each of the socioeconomic scenarios using epidemiological and operational variables such as tuberculosis mortality rate, AIDS case detection rate and proportion of vulnerable population among patients with tuberculosis. Some of the subscenarios identified were characterised by fragility in their information systems, while others were characterised by the concentration of tuberculosis cases in key populations. CONCLUSION: Clustering municipalities in scenarios allowed us to classify them according to the socioeconomic, epidemiological and operational variables associated with tuberculosis risk. This classification can support targeted evidence-based decisions such as monitoring data quality for improving the information system or establishing integrative social protective policies for key populations.

Qualifying information on deaths and serious injuries caused by road traffic in five Brazilian capitals using record linkage.

INTRODUCTION: Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity. OBJECTIVE: This study linked different data sources to measure the numbers of deaths and serious injuries and to estimate the percentage of corrections regarding the underlying cause of death, cause of injury, and the severity injury in victims in matched pairs from record linkage in five representative state capitals of the five macro-regions of Brazil. METHODS: This cross-sectional, population-based study used data from the Hospital Information System (HIS), Mortality Information System (MIS), and Police Road Traffic database of Belo Horizonte, Campo Grande, Curitiba, Palmas, and Teresina, for the year 2013 for Teresina, and 2012 for the other capitals. RecLink III was used to perform probabilistic record linkage by identifying matched pairs to calculate the global correction percentage of the underlying cause of death, the circumstance that caused the road traffic injury, and the injury severity of the victims in the police database. RESULTS: There was a change in the cause of injury in the HIS, with an overall percentage of correction estimated at 24.4% for Belo Horizonte, 96.9% for Campo Grande, 100.0% for Palmas, and 33.2% for Teresina. The overall percentages of correction of the underlying cause of death in the MIS were 29.9%, 11.9%, 4.2%, and 33.5% for Belo Horizonte, Campo Grande, Curitiba, and Teresina, respectively. The correction of the classification of injury severity in police database were 100.0% for Belo Horizonte and Teresina, 48.0% for Campo Grande, and 51.4% for Palmas after linkage with hospital database. The linkage between mortality and police database found a percentage of correction of 29.5%, 52.3%, 4.4%, 74.3 and 72.9% for Belo Horizonte, Campo Grande, Palmas, Curitiba and Teresina, respectively in the police records. CONCLUSIONS: The results showed the importance of linking records of the health and police databases for estimating the quality of data on road traffic injuries and the victims in the five capital cities studied. The true causes of death and degrees of severity of the injuries caused by RTC are underestimated in the absence of integration of health and police databases. Thus, it is necessary to define national rules and standards of integration between health and traffic databases in national and state levels in Brazil.

Confiabilidade do desfecho do tratamento usando linkagede bases de dados para a tuberculose / Reliability of treatment outcome for tuberculosis using record linkage

ResumoA qualidade da informação é fundamental no monitoramento e na avaliação das ações de controle dos agravos, como a tuberculose (TB). O objetivo deste trabalho foi analisar a concordância entre o encerramento do Sistema de Informação de Agravos de Notificação (SINAN) e as causas de morte no Sistema de Informação sobre Mortalidade (SIM). Realizou-se um linkage probabilístico entre o SINAN de 2006 e o SIM de 2006 a 2008. A confiabilidade do encerramento foi analisada por meio do índice kappa. Dos 417 casos encerrados por óbito no SINAN, 88,7% foram encontrados no SIM. Dos 82 casos encerrados como óbito por outra causa, 42,7% apresentaram a TB como causa básica ou associada no SIM, enquanto 41,5% não tinham menção à TB. O coeficiente PABAK (Prevalance and Bias Adjusted Kappa) revelou concordância excelente entre o desfecho óbito no campo encerramento do SINAN e a presença ou não do óbito de TB no SIM. Uma recomendação para os Estados e municípios que utilizam o relacionamento entre o SINAN e o SIM para aumentar a completude e a consistência do SINAN-TB é a investigação no SIM não apenas dos casos notificados sem encerramento, mas também dos casos encerrados por abandono e por transferência.

The quality of information is crucial in the monitoring and evaluation of control actions of diseases such as tuberculosis (TB). However, studies have pointed out deficiencies in the quality of data obtained by the TB surveillance system. Thus the aim of this study was to analyze the agreement between treatment outcome of the Notifiable Diseases Information System (SINAN) and information on the underlying and associated cause of death in the Mortality Information System (SIM). We conducted a probabilistic record linkage with the databases of the SINAN 2006 and the SIM 2006-2008. The accuracy of treatment outcome was analyzed by kappa index. Of the 417 cases closed as death in the SINAN, 88.7% were found in the SIM. Of the 82 cases closed as death from other causes, 42.7% presented TB as the underlying or associated cause in the SIM, while 41.5% did not mention TB. PABAK coefficients revealed excellent agreement between the treatment outcome of death of the SINAN and the presence or absence of TB death in the SIM. We recommend that the states and municipalities that use the linkage between the SINAN and SIM to increase the completeness and consistency of the SINAN-TB search on the SIM, not only for cases without treatment outcome, but also for those discontinued and transferred.

[What are the causes of death of patients with tuberculosis: multiple causes of death in a cohort of cases and a research proposal of presumed causes]. / Do que morrem os pacientes com tuberculose: causas múltiplas de morte de uma coorte de casos notificados e uma proposta de investigação de causas presumíveis.

The objective of this study was to analyze the multiple causes of death in a cohort of patients with tuberculosis (TB) and to introduce an investigation proposal death for TB from a list of presumable causes. We performed a probabilistic record linkage with the databases of the Information System for Notifiable Diseases (SINAN) 2006 and the Mortality Information System (SIM) 2006-2008. There were 825 deaths, of which 23% for death for TB, deaths due to TB with 16% and 61% without mention of TB. Two hundred and fifteen (42.7%) deaths occurred within the period of treatment, whose profile differed from the pattern of causes when TB was an associated cause, with high frequency of respiratory diseases, AIDS and ill-defined causes. We elaborated a proposal for correction of associated causes of death and an investigation proposal death for TB from a list of presumable causes. According to the proposal, 26 deaths could have modified the underlying cause. This study highlights the importance of record linkage to TB surveillance and improvement of information the SIM and SINAN.
