Development of an Index to Assess COVID-19 Hospital Care Installed Capacity in the 450 Brazilian Health Regions.

OBJECTIVE: The article seeks to assess the Brazilian health system ability to respond to the challenges imposed by the coronavirus disease 2019 (COVID-19) pandemic by measuring the capacity of Brazilian hospitals to care for COVID-19 cases in the 450 Health Regions of the country during the year 2020. Hospital capacity refers to the availability of hospital beds, equipment, and human resources. METHODS: We used longitudinal data from the National Register of Health Facilities (CNES) regarding the availability of resources necessary to care for patients with COVID-19 in inpatient facilities (public or private) from January to December 2020. Among the assessed resources are health professionals (certified nursing assistants, nurses, physical therapists, and doctors), hospital beds (clinical, intermediate care, and intensive care units), and medical equipment (computed tomography scanners, defibrillators, electrocardiograph monitors, ventilators, and resuscitators). In addition to conducting a descriptive analysis of absolute and relative data (per 10,000 users), a synthetic indicator named Installed Capacity Index (ICI) was calculated using the multivariate principal component analysis technique to assess hospital capacity. The indicator was further stratified into value ranges to understand its evolution. RESULTS: There was an increase in all selected indicators between January and December 2020. It was possible to observe differences between the Northeast and North regions and the other regions of the country; most Health Regions presented low ICI. The ICI increased between the beginning and the end of 2020, but this evolution differed among Health Regions. The average increase in the ICI was more evident in the groups that already had considerably high baseline capacity in January 2020. CONCLUSIONS: It was possible to identify inequalities in the hospital capacity to care for patients affected by COVID -19 in the Health Regions of Brazil, with a concentration of low index values in the Northeast and North of the country. As the indicator increased throughout the year 2020, inequalities were also observed. The information here provided may be used by health authorities, providers, and managers in planning and adjusting for future COVID-19 care and in dimensioning the adequate supply of hospital beds, health-care professionals, and devices in Health Regions to reduce associated morbidity and mortality. We recommend that the ICI continue to be calculated in the coming months of the pandemic to monitor the capacity in the country's Health Regions.

The disruption of elective procedures due to COVID-19 in Brazil in 2020.

Elective procedures were temporarily suspended several times over the course of the pandemic of COVID-19. Monthly data from the Unified Health System (SUS) were used for the period between January 2008 and December 2020 and the interrupted time series method was used to estimate the effect of the pandemic on the number of elective surgeries and elective procedures that were not performed. Considering a 9-month period, a reduction of 46% in the number of elective procedures carried out in the SUS could be attributed to COVID-19, corresponding to about 828,429 elective procedures cancelled, ranging from 549,921 to 1,106,936. To a full recovery of pre-pandemic performance, SUS would need to increase about 21,362 hospital beds, ranging from 12,370 to 36,392 hospital beds during a 6 month-period. This effort would represent an increase of 8.48% (ranging from 4.91 to 14.45%) in relation to the total number of SUS's hospital beds in 2019. As a result, the pandemic will leave a large number of elective procedures to be carried out, which will require efforts by health agencies to meet this demand.

Síndrome Inflamatória Multissistêmica e Covid-19 em crianças e adolescentes: aspectos epidemiológicos, Brasil, 2020-2021 / Multisystem Inflammatory Syndrome and COVID-19 in children and adolescents: epidemiological aspects, Brazil, 2020-20211

RESUMO Este estudo descreve aspectos epidemiológicos da Síndrome Inflamatória Multissistêmica Pediátrica (SIM-P) associada à Covid-19 e óbitos por Covid-19 em crianças (0-9 anos de idade) e adolescentes (10-19 anos de idade). As fontes de dados, de 2020-2021, foram os Sistemas de Vigilância Epidemiológica para SIM-P e de Informação sobre Mortalidade para Covid-19, gerenciados pelo Ministério da Saúde. Foram notificados 1.503 casos, mais frequentes em crianças (77%) do que em adolescentes (23%); e 93 óbitos por SIM-P em 26 das 27 Unidades da Federação. O maior número de casos em crianças foi notificado em São Paulo (268), contudo, a maior incidência ocorreu no Distrito Federal (7,8/100 mil habitantes). A proporção de óbitos por SIM-P foi 5,4% em crianças e 8,7% em adolescentes. No período avaliado, houve 2.329 óbitos por Covid-19 em menores de 20 anos de idade, com maior taxa em adolescentes (4,4/100 mil habitantes) do que em crianças (2,7/100 mil habitantes), com maiores taxas em Roraima. Recomenda-se intensificação da imunização contra Covid-19 nessa população, aumentando a proteção contra os efeitos negativos dessa doença e da SIM-P, que podem apresentar consequências em curto, médio e/ou longo prazo, de modo a não comprometer a inserção plena destes cidadãos na sociedade.

ABSTRACT This study describes epidemiological aspects of the Multisystemic Inflammatory Syndrome in Children (MIS-C) associated with COVID-19 and mortality by COVID-19 in children (0-9 years old) and adolescents (10-19 years old). The data sources, for 2020-2021, were the Epidemiological Surveillance System for MIS-C and Mortality Information System for COVID-19, both managed by the Ministry of Health. There were 1,503 cases, more frequent in children (77%) than in adolescents (23%), and 93 reported deaths due to MIS-C in 26 of the 27 States of the Country. The highest number of cases in children was reported in São Paulo (268), but the highest incidence took place in the Federal District (7.8 per 100,000 inhabitants). The rate of deaths due to MIS-C was 5.4% in children and 8.7% in adolescents. There were 2,329 deaths due to COVID-19 in the population under 20 years old, with a higher rate in adolescents (4.4 per 100,000 inhabitants) than in children (2.7); the highest rate occurred in Roraima. We recommend intensifying immunization against COVID-19 in such population, increasing protection against the negative effects of COVID-19 and MIS-C, which may have short, medium and/or long-term consequences, so as not to compromise the full integration of these citizens into society.

Efeito colateral da pandemia de Covid-19 no Brasil sobre o número de procedimentos diagnósticos e de tratamento da sífilis / Side effect of the COVID-19 pandemic in Brazil on the number of diagnostic and treatment procedures for syphilis / Efecto secundario de la pandemia de Covid-19 en Brasil sobre el número de procedimientos de diagnóstico y tratamiento de la sífilis

A sífilis, uma infecção vertical e sexualmente transmissível, curável e prevenível, é um problema de saúde pública no Brasil. Métodos diagnósticos e tratamentos são importantes no controle da doença. A pandemia de Covid-19 causou atrasos em diagnósticos e no tratamento na atenção primária em várias doenças e em diversos países, pois interrompeu padrões usuais de atendimento à saúde. O objetivo do estudo é identificar se houve menor número de procedimentos diagnósticos e de tratamento realizados para sífilis nos primeiros sete meses de 2020, comparativamente à média dos mesmos meses entre 2016 e 2019, no Brasil e nas unidades federativas. A redução no número de procedimentos seria um indicativo de atraso no diagnóstico, na detecção e no tratamento da sífilis em 2020. Foram utilizadas informações disponibilizadas no Sistema de Informações Ambulatoriais (SIA/SUS). Os achados para o Brasil indicaram queda de 1/3 nos procedimentos de diagnóstico e de tratamento referentes à sífilis nos sete primeiros meses do ano da pandemia, comparados com a média dos sete primeiros meses nos quatro anos anteriores (2016-2019). Indicadores mostram diferenças importantes por unidades da federação, apontando para maiores quedas proporcionais nos volumes de procedimentos no Norte e Nordeste, com ênfase nos estados do Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco e Amapá.

Syphilis, a vertical and sexually transmitted infection, curable and preventable, is a public health problem in Brazil. Diagnostic methods and treatments are important in controlling the disease. The COVID-19 pandemic caused delays in diagnosis and lack of treatment in primary care in several diseases and in several countries, as the pandemic disrupted usual health care standards. The aim of the study was to identify whether there were fewer diagnostic and treatment procedures performed for syphilis in the first seven months of 2020, compared to the average for the same months between 2016 and 2019, in Brazil and Federative Units. The reduction in the number of procedures would be indicative of a delay in the diagnosis, detection and treatment of syphilis in 2020. Information used came from the Outpatient Information System (SIA / SUS). The findings for Brazil indicated a 1/3 drop in diagnosis and treatment procedures for syphilis in the first seven months of the year of the COVID-19 pandemic, compared with the first seven months of the previous four years (2016-2019). Indicators showed important differences by Federation Units, pointing to greater proportional decrease in the volume of procedures in the North and Northeast, with an emphasis on Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco and Amapá.

La sífilis, una infección vertical y de transmisión sexual, curable y prevenible, es un problema de salud pública en Brasil. Los métodos de diagnóstico y los tratamientos son importantes para controlar la enfermedad. La pandemia de Covid-19 provocó retrasos en el diagnóstico y tratamiento en la atención primaria de variadas enfermedades en varios países, ya que interrumpió los estándares habituales de atención de la salud. El objetivo del estudio fue identificar si se realizaron menos procedimientos de diagnóstico y tratamiento de la sífilis en los primeros siete meses de 2020 en comparación con la media de los mismos meses entre 2016 y 2019, en Brasil y en sus unidades federativas. La reducción del número de procedimientos indicaría indicativo de un retraso en el diagnóstico, la detección temprana y el tratamiento de la sífilis en 2020. Para ello se utilizó la información disponible en el Sistema de Información Ambulatoria (SIA/SUS). Los hallazgos indicaron una caída de un tercio en los procedimientos de diagnóstico y tratamiento de la sífilis en los primeros siete meses del año de la pandemia de Covid-19 para Brasil, en comparación con los primeros siete meses de los cuatro años anteriores (2016-2019). Los indicadores mostraron diferencias importantes por unidades de la Federación, apuntando a mayores caídas proporcionales en el volumen de trámites en el Norte y Nordeste, con énfasis en Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco y Amapá.

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.

Trends in COVID-19 case-fatality rates in Brazilian public hospitals: A longitudinal cohort of 398,063 hospital admissions from 1st March to 3rd October 2020.

BACKGROUND: Almost 200,000 deaths from COVID-19 were reported in Brazil in 2020. The case fatality rate of a new infectious disease can vary by different risk factors and over time. We analysed the trends and associated factors of COVID-19 case fatality rates in Brazilian public hospital admissions during the first wave of the pandemic. METHODS: A retrospective cohort of all COVID-19-related admissions between epidemiological weeks 10-40 in the Brazilian Public Health System (SUS) was delimited from available reimbursement records. Smoothing time series and survival analyses were conducted to evaluate the trends of hospital case fatality rates (CFR) and the probability of death according to factors such as sex, age, ethnicity, comorbidities, length of stay and ICU use. RESULTS: With 398,063 admissions and 86,452 (21.7%) deaths, the overall age-standardized hospital CFR trend decreased throughout the period, varying from 31.8% (95%CI: 31.2 to 32.5%) in week 10 to 18.2% (95%CI: 17.6 to 18.8%) in week 40. This decreasing trend was observed in all sex, age, ethnic groups, length of stay and ICU admissions. Consistently, later admission (from July to September) was an independent protective factor. Patients 80+ year old had a hazard ratio of 8.18 (95% CI: 7.51 to 8.91). Ethnicity, comorbidities, and ICU need were also associated with the death risk. Although also decreasing, the CFR was always around 40-50% in people who needed an ICU admission. CONCLUSIONS: The overall hospital CFR of COVID-19 has decreased in Brazilian public hospitals during the first wave of the pandemic in 2020. Nevertheless, during the entire period, the CFR was still very high, suggesting the need for improving COVID-19 hospital care in Brazil.

Timely availability of public data for health management: COVID-19 wave´s analysis / Disponibilidade de dados públicos em tempo oportuno para a gestão: análise das ondas da COVID-19

The aim of this study is to support health management, with recent and reliable information, during the COVID-19 pandemic.  Notified and confirmed cases and deaths by COVID-19 were evaluated from three public databases. 1)  Data from the Coronavirus Panel of the Ministry of Health, updated daily, show the existence of two epidemic waves. 2)  The Civil Registry Transparency Portal, also with recent data, points to high mortality rates of COVID-19, especially in older age groups. 3)  The cases, reported by the Information System of the Epidemiological Surveillance of Influenza (Sivep-gripe), confirmed mainly by laboratory test, show predominance of men, high age groups, white race/color, residence in urban areas, presence of comorbidities, higher occurrence of hospitalization and lower use of intensive care unit. This last database, in addition to the first wave, records only the first eight epidemiological weeks of the second wave.  The vertiginous rate of increase in cases and deaths in the second wave points to the need for more drastic measures of social distancing, in addition to the expansion of vaccination against COVID-19. The combination of the three banks expands information that can support timely decision-making.

O objetivo deste estudo é apoiar a gestão em saúde, com informações recentes e confiáveis, durante a pandemia de COVID-19. Casos notificados e confirmados e óbitos por COVID-19 foram avaliados a partir de três bancos de dados públicos.1) Dados do Painel Coronavírus do Ministério da Saúde, atualizados diariamente, mostram a existência de duas ondas epidêmicas. 2) O Portal da Transparência do Registro Civil, também com dados recentes, aponta altas taxas de mortalidade do COVID-19, especialmente nas faixas etárias mais velhas. 3) Os casos notificados pelo Sistema de Informação da Vigilância Epidemiológica da Influenza (Sivep-gripe), confirmados principalmente por exame laboratorial, mostram predominância de homens, faixas etárias elevadas, raça/cor branca, residência em áreas urbanas, presença de comorbidades, maior ocorrência de internação e menor uso de unidade de terapia intensiva. Esta última base de dados, além da primeira onda, registra apenas as primeiras oito semanas epidemiológicas da segunda onda. A vertiginosa taxa de aumento de casos e óbitos na segunda onda aponta para a necessidade de medidas mais drásticas de distanciamento social, além da expansão da vacinação contra o COVID-19. A combinação dos três bancos expande as informações, que podem apoiar a tomada de decisões em tempo oportuno.

Inpatient flow for COVID-19 in the Brazilian health regions / Fluxo de internação por COVID-19 nas regiões de saúde do Brasil

Objective: To investigate the flows of hospitalizations for COVID-19 in the 450 regions and 117 Brazilian health macro-regions between March and October 2020. Method: Descriptive study, comprising all hospitalizations due to COVID-19 registered in the Flu Epidemiological Surveillance Information System (SIVEP-Gripe) between the 8th and 44th epidemiological weeks of 2020. The proportion of hospitalizations for COVID-19 occurred within same health region of residency was calculated, stratified according to periods of greater and lesser demand for health care, according to the population size of health regions. The indicator of migratory efficacy was calculated, which takes into account the evasion and invasion of patients, by crossing the data of origin of the patients (health region of residence) with the data of the place of hospitalization (health region of attendance). Results: 397,830 admissions were identified for COVID-19 in the period. Evasion was 11.9% of residents in health regions and 6.8% in macro-regions, pattern that was maintained during the peak period of hospitalizations for COVID-19. There was an average of 17.6% of evasion of residents of health regions in the Northeast and of 8.8% in health regions of the South. Evasion was more accentuated in health regions with up to 100 thousand / inhabitants (36.9%), which was 7 times greater than that observed in health regions with more than 2 million / inhabitants (5.2%). The negative migratory efficacy indicator (-0.39) indicated a predominance of evasion. Of the 450 Brazilian health regions, 117 (39.3%) had a coefficient of migratory efficacy between -1 and -0.75 and 113 (25.1%) between -0.75 and -0.25. Conclusion: The results indicate that the regionalization of the health system proved to be adequate in the organization of care in the territory, however the long distances traveled are still worrying.

Foi calculada a proporção das internações por COVID-19 realizadas pelos residentes que ocorreram dentro da sua respectiva região de saúde, estratificado segundo períodos de maior e menor demanda de internações e segundo o porte populacional das regiões de saúde. Foi calculado o indicador de eficácia migratória, que leva em consideração a evasão e invasão de pacientes, por meio do cruzamento dos dados de origem dos pacientes (região de saúde de residência) com os dados do local da realização das internações (região de saúde de atendimento). Resultados: Foram identificadas 397.830 internações por COVID-19 no Brasil. A evasão foi de 11,9% dos residentes nas regiões de saúde e de 6,8% nas macrorregiões; o padrão que se manteve também no período de pico das internações por COVID-19. Houve em média 17,6% de evasão dos residentes das regiões de saúde do Nordeste e de 8,8% nas regiões de saúde do Sul. A evasão foi mais acentuada nas regiões de saúde com até 100 mil/hab. (36,9%), a qual foi 7 vezes maior que a verificada nas regiões de saúde com mais de 2 milhões/habitantes (5,2%). O indicador de eficácia migratória negativo (-0,39) indicou predomínio da evasão. Das 450 regiões de saúde brasileiras, 117 (39,3%) apresentaram coeficiente de eficácia migratória entre -1 e -0,75 e 113 (25,1%) entre -0,75 e -0,25. Conclusão: Os resultados indicam que a regionalização do sistema de saúde mostrou-se adequada na organização do atendimento no território, porém as longas distâncias percorridas ainda são preocupantes

Human papillomavirus vaccine and risky sexual behavior: Regression discontinuity design evidence from Brazil.

This study aims to analyze the hypothesis of moral hazard caused by vaccination against human papillomavirus (HPV), regarding girls' beginning of sex life and, once they have begun their sex life, to understand whether it reduces the probability of girls using a condom in their first sexual intercourse. The data are from the 2015 National Survey of School Health (PeNSE). The model used is the regression discontinuity, with the discontinuity in the age of the girls who were able to participate in the public vaccination campaign. The results of the so-called Fuzzy-RDD show that the campaign was effective in increasing the likelihood of vaccination by 26.7-27.6 percentage points. There is no observable effect on young women initiating their sex lives or refraining from using condoms. The results are tested by several robustness methods. This is the first work to use quasi-experimental models in a developing country with low vaccination coverage in Latin America and show that it is necessary to increase awareness campaigns with parents, so they will know that there is no effect of vaccination on the beginning of sex life and condom use.

A gender analysis of the impact of physical education on the mental health of brazilian schoolchildren.

This paper investigates the effect of attending physical education classes on mental health indicators - loneliness and insomnia - of Brazilian schoolchildren. The identification strategy consists of separating the sample into two parts: people who practice physical activity and who attend physical education classes at school and people who, despite not attending physical education classes, practice physical activities. The data are from the 2015 National Adolescent School-based Health Survey (PeNSE), and the sample pairing method is the Propensity Score Matching with robustness analysis using the Bivariate Probit method and the sensitivity is tested using the method developed by Ichino, Mealli, and Nannicini (2008). For both girls and boys the results showed that physical education exerts a negative effect, reducing the probability of reporting problems of insomnia and loneliness among schoolchildren who attend the discipline. Although they show similar magnitudes, the observed effects are greater for boys, in both measures. The study investigates - in a rigorous and unprecedented way in the literature - the effect of physical education classes on the insomnia and loneliness of Brazilian school children. The results are important for the formulation of discipline maintenance policies in the curriculum of schoolchildren in Brazil.

Factors associated with family, school and behavioral characteristics on sexual initiation: A gender analysis for Brazilian adolescents.

Adolescence is a period of transition between childhood and adulthood. The article aims to study the individual, family and school characteristics of adolescents beginning their sexual lives. The database we used was the 2015 PeNSE (National Adolescent School-based Health Survey) and the methodology was the survival analysis. The results show that boys initiate sexual activity before girls and risky behaviors associated with the use of licit and illicit drugs increase the chance of having early sex. In addition, this work highlights the importance of parental practices in reducing the chances of beginning sexual activity, as well as the presence of school workshops on the risks of pregnancy. It should be noted that intervention strategies need to be differentiated according to gender in order to increase effectiveness.

Os arranjos familiares importam no momento de decidir em qual rede de ensino matricular os filhos? / Do family arrangements affect parents' decision of school for their children? / ¿Importan los arreglos familiares a la hora de decidir en qué red de enseñanza matricular a los hijos?

O presente trabalho tem como objetivo analisar se os arranjos familiares (monoparentais ou biparentais) afetam na escolha parental de qual rede de ensino (pública ou privada) matricular os filhos. Utilizando os dados da Pesquisa Nacional por Amostra de Domicílios (PNAD) de 2015, os resultados apontaram para dissemelhanças entre os arranjos familiares, as quais podem ser explicadas pelas diferenças nas preferências dos indivíduos, assim como na renda familiar. Verifica-se que existe maior probabilidade de as famílias investirem privadamente no ensino infantil. A evidência pode ser decorrente da oferta reduzida de creches públicas. Segundo a ordem de nascimento, para os arranjos familiares monoparental feminino e casal com filhos, as famílias preferem investir no filho mais velho, em detrimento dos demais filhos. Além disso, verificou-se que o filho do sexo masculino tem menores chances de estudar em uma rede privada caso esteja em um arranjo monoparental feminino. Esse resultado pode mostrar uma preferência da mãe em incentivar o estudo da filha em uma tentativa de empoderá-la.

This study aims to analyze whether family arrangements (single-parent or two-parent) influence the choice of school system (public or private) for children. For this analysis, data from the 2015 National Household Sample Survey (PNAD) were used. Results point to dissimilarities among family arrangements which can be explained by differences in individual preferences as well as in family income. We found that families are more likely to invest privately in early childhood education. The evidence may be due to the small number of public day care centers. According to the order of birth, families can invest in their eldest child to the detriment of their other children, in the case of female single-parent and two-parent family arrangements. In addition, we found that male children were less likely to study in a private school in female single-parent arrangement. This result may show mothers' wishes to encourage daughters to study in an attempt to empower them.

El objetivo de este trabajo es analizar si los arreglos familiares (monoparentales o biparentales) afectan la elección parental del tipo de institución (pública o privada) en la cual serán matriculados los hijos. Para este analísis fueron utilizados los datos tomados de la Pesquisa Nacional por Amostra de Domicílios (PNAD) de 2015. Los resultados apuntan a que las diferencias en la conformación de las familias pueden ser explicadas por las preferencias de los individuos así como por su enta familiar. Se observa que existe mayor probabilidad de que las familias inviertan en educación privada durante la educación infantil. No obstante, esto puede deberse a la falta de oferta de este servicio en la red de instituciones públicas. Asimismo, de acuerdo al orden de los hijos, se prefiere invertir en el hijo mayor en detrimento de los demás hijos, especialmente los arreglos familiares monoparentales femeninos o biparentales en matrimonio. A su vez, se encontró que el hijo de sexo masculino tiene menos oportunidades de estudiar en una institución privada en una familia con arreglo monoparental femenino. Este resultado puede evidenciar la preferencia de la madre a incentivar el estudio en la hija mujer, en una tentativa de buscar su empoderamiento.
