Are heart attacks deadlier on weekends? Evidence of weekend effect in Brazil.

This article aims to examine the effects of weekend admission on in-hospital mortality for patients with acute myocardial infarction (AMI) in Brazil. Information from the Hospital Information System of the Unified Health System (SIH/SUS) of urgently admitted patients diagnosed with acute myocardial infarction (AMI) between 2008 and 2018 was used, made available through the Hospital Admission Authorization (AIH). Multivariable logistic regression models, controlling for observable patient characteristics, hospital characteristics and year and hospital-fixed effects, were used. The results were consistent with the existence of the weekend effect. For the model adjusted with the inclusion of all controls, the chance of death observed for individuals hospitalized on the weekend is 14% higher. Our results indicated that there is probably an important variation in the quality of hospital care depending on the day the patient is hospitalized. Weekend admissions were associated with in-hospital AMI mortality in Brazil. Future research should analyze the possible channels behind the weekend effect to support public policies that can effectively make healthcare equitable.

Validation study of obstetric hospitalization data held on the Brazilian National Health System Hospital Information System for maternal morbidity surveillance: Brazil, 2021-2022.

OBJECTIVE: To validate the Brazilian National Health System Hospital Information System (SIH/SUS) for maternal morbidity surveillance. METHODS: This was a cross-sectional study conducted in 2021/2022, taking as its reference a national study on maternal morbidity (MMG) conducted in 50 public and 28 private hospitals; we compared SIH/SUS and MMG data for hospitalization frequency, reason and type of discharge and calculated sensitivity, specificity, positive and negative likelihood ratios for seven diagnoses and four procedures. RESULTS: Hospitalizations identified on SIH/SUS (32,212) corresponded to 95.1% of hospitalizations assessed by MMG (33,867), with lower recording on SIH/SUS (85.5%) for private hospitals [10,036 (SIH/SUS)]; 11,742 (MMG)]; compared to MMG, SIH/SUS had a lower proportion of hospitalizations due to "complications during pregnancy" (9.7% versus 16.5%) as well as under-recording of all diagnoses and procedures assessed, except "ectopic pregnancy". CONCLUSION: Better recording of diagnoses and procedures on SIH/SUS is essential for its use in maternal morbidity surveillance.

Improvements in data completeness in health information systems reveal racial inequalities: longitudinal national data from hospital admissions in Brazil 2010-2022.

BACKGROUND: Race and ethnicity are important drivers of health inequalities worldwide. However, the recording of race/ethnicity in data systems is frequently insufficient, particularly in low- and middle-income countries. The aim of this study is to descriptively analyse trends in data completeness in race/color records in hospital admissions and the rates of hospitalizations by various causes for Blacks and Whites individuals. METHODS: We conducted a longitudinal analysis, examining hospital admission data from Brazil's Hospital Information System (SIH) between 2010 and 2022, and analysed trends in reporting completeness and racial inequalities. These hospitalization records were examined based on year, quarter, cause of admission (using International Classification of Diseases (ICD-10) codes), and race/color (categorized as Black, White, or missing). We examined the patterns in hospitalization rates and the prevalence of missing data over a period of time. RESULTS: Over the study period, there was a notable improvement in data completeness regarding race/color in hospital admissions in Brazil. The proportion of missing values on race decreased from 34.7% in 2010 to 21.2% in 2020. As data completeness improved, racial inequalities in hospitalization rates became more evident - across several causes, including assaults, tuberculosis, hypertensive diseases, at-risk hospitalizations during pregnancy and motorcycle accidents. CONCLUSIONS: The study highlights the critical role of data quality in identifying and addressing racial health inequalities. Improved data completeness has revealed previously hidden inequalities in health records, emphasizing the need for comprehensive data collection to inform equitable health policies and interventions. Policymakers working in areas where socioeconomic data reporting (including on race and ethnicity) is suboptimal, should address data completeness to fully understand the scale of health inequalities.

Hospitalizations for mental and behavioral disorders due to alcohol and other psychoactive substance use among adolescents in Brazil, 2017-2022.

OBJECTIVE: To assess the epidemiological profile and trend in hospitalizations for mental and behavioral disorders due to alcohol and other psychoactive substance use among Brazilian adolescents, between 2017 and 2022. METHODS: This was a time-series study using data from the Hospital Information System of the Brazilian National Health System; the trend analysis was performed by estimating the annual percentage change (APC) of hospitalization rates per 100,000 inhabitants and respective confidence intervals (95%CI), using the Prais-Winsten method. RESULTS: A total of 29,991 hospitalizations were recorded in the study period, with a decreasing trend observed, from 16.18/100,000 inhabitants in 2017 to 13.72/100,000 inhab. in 2022 (percent change of -2.65%; 95%CI -4.47;-0.80), a greater decline was found in males (-3.48%; 95%CI -5.20;-1.72), in the age group of 15 to 19 years (-2.79%; 95%CI -4.49;-1.06), in the South (-3.29%; 95%CI -5.37;-1.16) and Midwest (-3.64%; 95%CI -5.75;-1.49) regions of the country. CONCLUSION: Hospitalizations showed a decreasing trend in the study period, with sociodemographic disparities.

Hospitalizations in older adults from the Zona da Mata of Minas Gerais, Brazil: data from the Unified Health System, 2016­2018 / Hospitalizações em idosos da Zona da Mata de Minas Gerais, Brasil: dados do Sistema Único de Saúde, 2016­2018

INTRODUCTION: The growing older population increases proportionately the demand for hospital care due to the increase in health problems. OBJECTIVE: To estimate the prevalence and incidence of hospitalizations, and to investigate associated factors in older adults from the Zona da Mata of Minas Gerais, Brazil, between 2016-2018. Secondly, to provide a more comprehensive epidemiological overview of hospitalizations, the following were estimated: monthly hospitalization rate; hospital mortality rate; frequency of hospitalizations according to diagnosis, hospitalizations for conditions sensitive to primary care and in-hospital death; and hospital costs. METHODS: This is an ecological and descriptive-analytic study. Data were obtained from the Brazilian Hospital Information System (SIH/SUS). RESULTS: The prevalence of hospitalizations was 35.1% (31.2% in women and 39.7% in men). The monthly rate of hospitalizations was higher in older men when compared with older women (Rate-Ratio=1.35 [95% CI=1.27-1.43]) and adult men between 40­59 years (Rate Ratio=2.42 [95% CI=2.26-2.58]). The cumulative incidence of hospitalization was 144/1,000 older persons (125/1,000 women and 169/1,000 men). Factors significantly associated with hospitalizations were: male sex (PR=1.52 [95% CI=1.11-2.08]); hospitalization in surgical bed (PR=1.93 [95% CI=1.05-3.56]); absence of death (PR=1.94 [95% CI=1.03-3.65]); and hospital stay ≥15 days (PR=0.71 [95% CI=0.54 0.95]). The cost of hospitalizations was R$ 220,8 million (mean of R$ 201,700/day). CONCLUSÃO: The findings strengthen the need for preventive healthcare for the older population living in the Zona da Mata of Minas Gerais and alert managers to the substantial socioeconomic impact of hospitalizations.

Incomplete recording of race/colour in health information systems in Brazil: time trend, 2009-2018. / Tendência temporal da incompletude do registro da raça/cor nos sistemas de informação em saúde do Brasil, 2009-2018.

This ecological study of time trends and multiple groups evaluated incompleteness in the race/colour field of Brazilian health information system records and the related time trend, 2009-2018, for the diseases and disorders most prevalent in the black population. The Romero and Cunha (2006) classification was applied in order to examine incompleteness using secondary data from Brazil's National Notifiable Diseases System, Hospital Information System and Mortality Information System, by administrative regions of Brazil, while percentage underreporting and time trend were calculated using simple linear regression models with Prais-Winsten correction (p-value<0.05). All records scored poorly except those for mortality from external causes (excellent), tuberculosis (good) and infant mortality (fair). An overall downward trend was observed in percentage incompleteness. Analysis by region found highest mean incompleteness in the North (30.5%), Northeast (33.3%) and Midwest (33.0%) regions. The Southeast and Northeast regions showed the strongest downward trends. The findings intended to increase visibility on the implications of the race/color field for health equity.

Propõe-se avaliar a incompletude e a tendência temporal do preenchimento do campo raça/cor das doenças e agravos mais prevalentes na população negra nos Sistemas de Informação em Saúde do Brasil, 2009-2018. Trata-se de estudo ecológico de tendência temporal e múltiplos grupos. Foi adotada a classificação de Romero e Cunha (2006) para análise da incompletude e utilizados dados secundários do Sistema Nacional de Agravos de Notificação, Sistema de Informações Hospitalares e Sistema de Informações sobre Mortalidade do Brasil e regiões brasileiras, calculada a proporção de subnotificação e a tendência temporal, utilizando o modelo de regressão linear simples, com correção Prais-Winsten (p-valor<0,05). Excetuando-se os registros de mortalidade por causas externas (excelente), tuberculose (bom) e mortalidade infantil (regular), todos os registros apresentaram escore ruim. Observou-se tendência decrescente da proporção de incompletude. A análise por região mostrou que as maiores médias de incompletude foram registradas na região Norte (30,5%), Nordeste (33,3%) e Centro-Oeste (33,0%). As regiões Sudeste e Nordeste foram as que mais apresentaram tendência decrescente. Os resultados visam ampliar a visibilidade acerca das implicações do preenchimento do campo raça/cor para a equidade em saúde.

The Large-Scale Implementation of a Health Information System in Brazilian University Hospitals: Process and Outcomes.

Governments around the globe are paving the way for healthcare services that can have a profound impact on the overall well-being and development of their nations. However, government programs to implement health information technologies on a large-scale are challenging, especially in developing countries. In this article, the process and outcomes of the large-scale implementation of a hospital information system for the management of Brazilian university hospitals are analyzed. Based on a qualitative approach, this research involved 21 hospitals and comprised a documentary search, interviews with 24 hospital managers and two system user focus groups, and a questionnaire of 736 respondents. Generally, we observed that aspects relating to the wider context of system implementation (macro level), the managerial structure, cultural nuances, and political dynamics within each hospital (meso level), as well as the technology, work activities, and individuals themselves (micro level) acted as facilitators and/or obstacles to the implementation process. The dynamics and complex interactions established between these aspects had repercussions on the process, including the extended time necessary to implement the national program and the somewhat mixed outcomes obtained by hospitals in the national network. Mostly positive, these outcomes were linked to the eight emerging dimensions of practices and work processes; planning, control, and decision making; transparency and accountability; optimization in the use of resources; productivity of professionals; patient information security; safety and quality of care; and improvement in teaching and research. We argued here that to maximize the potential of information technology in healthcare on a large-scale, an integrative and cooperative vision is required, along with a high capacity for change management, considering the different regional, local, and institutional contexts.

[Spatial analysis of maternal morbidity and mortality in users of the Brazilian Unified National Health System in the city of Rio de Janeiro, Brazil, 2014-2016]. / Análise espacial da morbimortalidade materna em usuárias do Sistema Único de Saúde no Município do Rio de Janeiro, Brasil, 2014-2016.

The objective of this study is to analyze the maternal morbidity and mortality of women treated in hospitals of the Brazilian Unified National Health System (SUS) in the city of Rio de Janeiro in the period 2014-2016. An ecological study was conducted using data from the Brazilian Information System on Live Birth (SINASC), the Brazilian Mortality Information System (SIM), and the Brazilian Hospital Information System (SIH/SUS). For the analysis of the maternal mortality ratio (MMR), data from the SIM were used. For the analysis of maternal morbidity, World Health Organization criteria were used to estimate the ratios of maternal near miss and potentially life-threatening conditions. SINASC was used to retrieve data on the number of live births, for demographic characterization, social aspects, and access to prenatal care. To evaluate the spatial association between the indicators MMR, ratios of maternal near miss, and potentially life-threatening conditions and the demographic, social, obstetric, and access indicators, obtained from SINASC, the bivariate Moran Index was estimated with a significance level of 0.05, using the GeoDa program. In the period analyzed, the MMR in the Rio de Janeiro was 94.16/100,000 live births, the ratio of maternal near miss was 28.21/1,000 live births, and the potentially life-threatening conditions was 34.31/1,000 live births. Cases of potentially life-threatening conditions were used for the first time in this study and presented diagnoses and procedures during hospitalization more consistent with the maternal mortality profile in the city of Rio de Janeiro. There was a significant association between MMR and percentage of live births in SUS, potentially life-threatening conditions and percentage of live births in SUS, and potentially life-threatening conditions and being single.

O objetivo deste estudo é analisar a morbimortalidade materna de mulheres atendidas em hospitais do Sistema Único de Saúde (SUS) no Município do Rio de Janeiro, Brasil, no período de 2014 a 2016. Foi realizado estudo ecológico, por meio da coleta de dados do Sistema de Informações sobre Nascidos Vivos (SINASC), Sistema de Informação sobre Mortalidade (SIM) e Sistema de Informações Hospitalares (SIH/SUS). Para analisar a razão de mortalidade materna (RMM), foram utilizados dados do SIM. Para investigar a morbidade materna, adotaram-se critérios da Organização Mundial da Saúde para estimar as razões de near miss materno e de condições potencialmente ameaçadoras à vida. Dados do SINASC foram usados para número de nascidos vivos e caracterização demográfica, social e de acesso a serviço de pré-natal. Para avaliar a associação espacial entre os indicadores RMM, razões de near miss materno e condições potencialmente ameaçadoras à vida e os indicadores demográficos, sociais, obstétricos e de acesso obtidos no SINASC, foi calculado o índice de Moran bivariado com nível de 0,05 de significância, por meio do programa GeoDa. No período analisado, a RMM no Município do Rio de Janeiro foi de 94,16/100 mil nascidos vivos, a razão de near miss materno de 28,21/1.000 nascidos vivos e a razão de condições potencialmente ameaçadoras à vida de 34,31/1.000 nascidos vivos. Casos de condições potencialmente ameaçadoras à vida foram utilizados pela primeira vez neste estudo e apresentaram diagnósticos de internação e procedimentos realizados mais condizentes com o perfil de mortalidade materna no Município do Rio de Janeiro. Houve associação significativa entre RMM e percentual de nascidos vivos no SUS, razão de condições potencialmente ameaçadoras à vida e percentual de nascidos vivos no SUS e razão de condições potencialmente ameaçadoras à vida e ser solteira.

Usefulness of the Hospital Information System for maternal mortality surveillance in Brazil. / Utilidade do Sistema de Informação Hospitalar na vigilância da mortalidade materna no Brasil.

OBJECTIVE: To evaluate the capability of hospital records in the Hospital Information System (SIH) to add valuable and complementary information to the Mortality Information System (SIM) in studies on maternal mortality. We calculated and compared the maternal mortality ratio from the SIH and SIM databases, by age group and region, to highlight differences between groups and assess the coverage of maternal deaths using SIH compared with SIM. METHODS: Obstetric hospitalizations were defined based on three sources (codes ICD-10 in diagnoses; procedures; billing information). Hospital and SIM mortality ratios were calculated by dividing maternal deaths in hospitals affiliated to the Unified Brazilian Health System (SUS) per live births (SINASC) in the same hospitals. RESULTS: In 2019, we identified 2,497,957 obstetric admissions, 0.04% (946) with in-hospital mortality as outcome. The presence of three criteria identified 98% of obstetric hospitalizations and 83% of obstetric hospitalizations with death as outcome. The comparison of mortality ratios between SIH (45.5 MMR; 95%CI 42.7 - 48.5) and SIM (49.7 MMR; 95%CI 46.7 - 52.8) was not statistically significant (p-value: 0.053). CONCLUSION: The analysis of SIH was able to provide additional information for the monitoring and surveillance of maternal health in Brazil. Although there are differences between the mortality rates, the SIH, as a complementary information system to the SIM, may be valid in studies on maternal mortality and morbidity.

OBJETIVO: Avaliar a capacidade dos registros hospitalares (SIH) em adicionar informações úteis e complementares ao Sistema de Informações sobre Mortalidade (SIM) no entendimento da mortalidade materna. Calcular e comparar a Razão de Mortalidade Materna (RMM) hospitalar e a RMM do SIM dos óbitos maternos ocorridos em hospitais, por faixa etária e por região, para demonstrar diferenças entre os grupos e avaliar a cobertura de óbitos maternos do SIM em relação ao SIH. MÉTODOS: As internações obstétricas foram definidas com base em três critérios (códigos da 10a Revisão da Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde ­ CID-10 nos diagnósticos; procedimentos; cobrança de parto). As RMM hospitalar e do SIM foram calculadas dividindo-se os óbitos maternos ocorridos nos hospitais conveniados ao Sistema Único de Saúde (SUS) pelos nascidos vivos (Sistema de Informação sobre Nascidos Vivos ­ SINASC) desses estabelecimentos. RESULTADOS: Em 2019, identificamos 2.497.957 registros de internações obstétricas, 0,04% (946) com óbito hospitalar. Os três critérios localizaram 98% das internações obstétricas e 83% das internações com óbitos, revelando inconsistências entre diagnósticos e procedimentos. A comparação entre a RMM do SIH (45,5, intervalo de confiança ­ IC95%, 42,7­48,5) e a do SIM (49,7, IC95%, 46,7­52,8) não foi estatisticamente significante (p-valor 0,053). CONCLUSÃO: A análise do SIH foi capaz de prover informações adicionais ao monitoramento e vigilância da saúde materna no Brasil. Embora haja diferenças entre as RMM, o SIH como sistema de informação complementar ao SIM pode ser válido nos estudos sobre mortalidade e morbidade materna.

Profile of hospitalization in the health unic system in the municipality of São Paulo for acute myocardial infarction in the year 2021

INTRODUCTION: Despite significant scientific advances and public prevention policies, acute myocardial infarction corresponds to a high rate of hospitalizations and morbidity and mortality. OBJECTIVE: To analyze and describe the profile of patients who are hospitalized in the city of São Paulo for Acute Myocardial Infarction in the year 2021. METHODOLOGY: It consists of a descriptive, retrospective, longitudinal epidemiological study, based on the analysis of a secondary source of data, with the aim of the studies being hospital admissions in the Unified Health System of the city of São Paulo, in the year 2021, for causes related to diseases. hypertensive As inclusion criteria, all hospital admissions were selected through the Hospital Information System (SIH), through DATASUS. The period studied was the year 2021. The morbidities were separated and selected according to the main hospitalization diagnosis and classified according to the International Disease Code 10 (ICD10), the following being selected: I10 -Essential hypertension, I11 - Hypertensive heart disease , I12 - Hypertensive kidney disease, I13 - Hypertensive heart and kidney disease, I15 - Secondary hypertension. Gender, race/color and age group were also taken into account. RESULTS: During the study period, 2219 hospitalizations were performed for hypertensive diseases, of which 49.2% were male and 50.8% female. Among the target audience of the study, when considering race/color, 35.8% of patients consider themselves white, 8% black, 29.5% brown and 0.2% yellow. 26.5% of the registered admissions had no description of race/color. Regarding the age groups studied, there is a gradual increase in the number of hospitalizations as the observed age group also increases, with the group of patients over 80 years of age having the highest number of hospitalizations, corresponding to 14% of all the hospitalizations. CONCLUSION: Hospitalizations in the city of São Paulo due to hypertensive syndromes were slightly higher in males, most of whom were white and aged over 80 years.

Costs of hospital admission authorizations due to falls among older people in the Brazilian National Health System, Brazil, 2000-2020: a descriptive study. / Custos das autorizações de internação hospitalar por quedas de idosos no Sistema Único de Saúde, Brasil, 2000-2020: um estudo descritivo.

OBJECTIVE: To describe the costs of hospital admission authorizations (AIHs) due to falls among older people within the Brazilian National Health System (SUS). METHODS: This was a descriptive cost analysis study, based on data from the SUS's Hospital Information System, related to AIH due to falls among older people (60 years and older), between 2000 to 2020. A descriptive analysis was performed and cost measurement was based on a macro-costing method. RESULTS: 1,746,097 AIHs due to falls among older people were recorded, and the total cost was found to be BRL 2,315,395,702.75. The proportion of hospitalization costs was higher among those aged 80 years and older (36.9%), female (60.4%) and the Southeast region of the country (57.3%). The average length of stay in hospital ranged from 5.2 to 7.5 days. CONCLUSION: The high costs identified showed the need for investments in more effective measures in order to prevent and mitigate the damage caused by falls among older people.

Analysis of trends in sepsis mortality in Brazil and by regions from 2010 to 2019.

OBJECTIVE: To characterize the profile of inpatients and trend of sepsis mortality in the Brazilian Unified Health System (SUS), throughout Brazil, and in its regions separately, from 2010 to 2019. METHODS: Observational, analytical and retrospective study of secondary data obtained through consultation to the Sistema de Informação Hospitalar (Hospital Information System). All incoming septicemia notifications from January 1, 2010 to December 31, 2019 were included. The following sociodemographic variables were used: sex, age, race, region and federative unit of residence. For data analysis, we used mortality and hospitalization coefficient, relative risk and Joinpoint regression. RESULTS: There were a total of 1,044,227 cases of sepsis in Brazil, yielding a mean prevalence coefficient of 51.3/100 thousand inhabitants. There were 463,000 deaths from sepsis recorded, with a mean prevalence coefficient of 22.8 deaths/100,000 inhabitants. The highest rates occurred among the elderly, of brown race, and there was no significant difference between genders. The Southeast region accounted for the highest rates of hospitalization and deaths. A general trend toward increased mortality was observed in the period studied. CONCLUSION: The heterogeneity of Brazil should be considered regarding socioeconomic and demographic characteristics, and differences in health investment and underreporting between regions, in order to understand the disease's epidemiological course. Finally, these findings should be correlated with other studies, in an effort to understand the behavior of the disease, and provide inputs for public and private policies in order to reduce the expressiveness of cases and deaths from sepsis in Brazil.

Tendências temporais de internações de crianças por condições sensíveis à atenção primária em Minas Gerais, Brasil / Tendencias temporales de admisión infantil por condiciones sensibles a la atención primaria en Minas Gerais, Brasil / Temporal tendencies in hospitalization of children for primary care-sensitive conditions in Minas Gerais, Brazil

RESUMO Objetivo: analisar a tendência das internações por condições sensíveis à atenção primária em crianças menores de cinco anos de idade, no estado de Minas Gerais. Métodos: estudo ecológico de séries temporais utilizou registros do Sistema de Informação Hospitalar, período de 2008 a 2018. As análises de tendência foram realizadas pelo método de Prais-Winsten para verificar tendências: estacionárias (p > 0,05), decrescentes (p < 0,05 e coeficiente de regressão negativo) ou ascendentes (p < 0,05 e coeficiente de regressão positivo) por região de saúde e por grupo etário (até um ano e de um a quatro anos). Resultados: houve tendência decrescente de internações entre crianças no estado (variação percentual anual = -4,96%; p < 0,05), com redução de internações por gastroenterites infecciosas e complicações, pneumonias bacterianas e asma. Observou-se aumento de internações por anemia; doenças pulmonares e infecções de ouvido, nariz e garganta. Para crianças menores de um ano, foi observado que as internações por doenças preveníveis por imunização e condições sensíveis apresentaram tendência ascendente (ß=5,69 e p < 0,05), com destaque para a sífilis congênita. Conclusões: o cenário de Minas Gerais é similar ao de outros estados brasileiros, nos quais se observa redução de internação de crianças de até cinco anos, com aumento de internações por anemia, doenças pulmonares e infecção de ouvido, nariz e garganta. Ainda que existam melhorias nas práticas e políticas voltadas para a saúde da criança, os achados reforçam o planejamento de ações para o cuidado a agravos preveníveis na atenção primária.

Conclusiones: el escenario en Minas Gerais es similar al de otros estados brasileños, en los que hay una reducción en el número de hospitalizaciones de niños hasta los cinco años, con un aumento de las hospitalizaciones por anemia, enfermedades pulmonares y de oído, nariz e infecciones de garganta. Si bien existen mejoras en las prácticas y políticas orientadas a la salud infantil, los hallazgos refuerzan la planificación de acciones para la atención de enfermedades prevenibles en atención primaria.

ABSTRACT Objective: to analyze the tendency of hospitalizations for primary care-sensitive conditions in children under five years of age in the state of Minas Gerais. Methods: an ecological time series study used records from the Hospital Information System, from 2008 to 2018. Tendency analyzes were performed using the Prais-Winsten method to verify tendencies: stationary (p > 0.05), decreasing (p < 0.05 and negative regression coefficient) or increasing (p < 0.05 and positive regression coefficient) by health region and by age group (up to one year and from one to four years). Results: there was a downward tendency in hospitalizations among children in the state (annual percentage variation = -4.96%; p < 0.05), with a reduction in hospitalizations for infectious gastroenteritis and complications, bacterial pneumonia, and asthma. An increase in hospitalizations due to anemia was observed, lung diseases and ear, nose, and throat infections. For children under one year old, it was observed that hospitalizations for diseases preventable by immunization and sensitive conditions showed an upward tendency (ß=5.69 and p < 0.05), with emphasis on congenital syphilis. Conclusions: the scenario of Minas Gerais is similar to that of other Brazilian states, in which there is a reduction in hospitalization of children up to five years old, with an increase in hospitalizations for anemia, lung diseases and ear, nose and throat infections. Although there are improvements in practices and policies aimed at children's health, the findings reinforce the planning of actions for the care of preventable diseases in primary care.
