Indicators of the National Immunization Program for children under one year old: time trend in Maranhão, Brazil, 2010 to 2021. CIENCIA & SAUDE COLETIVA 2023; 28:2335-2346. [PMID: 37531541 DOI: 10.1590/1413-81232023288.07312023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Accepted: 04/17/2023] [Indexed: 08/04/2023] Open
Abstract
We aimed to analyze the trend of indicators of the National Immunization Program (acronym in Portuguese. PNI) in children under one-year-old and classify municipalities regarding the risk of transmission of vaccine-preventable diseases (RTVPD) in Maranhão from 2010 to 2021. This ecological time series study was based on secondary data on vaccination coverage (VC). vaccination coverage homogeneity (VCH). proportion of abandonment (PA). and RTVPD. with state coverage for vaccines in the national children's calendar. Prais-Winsten regression estimated trends (α=5%) and the indicators' annual percentage change (APC). We identified fluctuating and discrepant VC between vaccines. with a decreasing trend (p < 0.01). except those against Hepatitis B (p = 0.709) and oral human rotavirus (p = 0.143). The sharpest falls were for Yellow Fever (APC = 12.24%) and BCG (APC = 12.25%) vaccines. All VCH rates were lower than expected. with a drop from 2014 and APC between 5.75% (Pneumococcal 10; p = 0.033) and 14.02% (Poliomyelitis; p < 0.01). We observed an increasing trend in PA for Pentavalent (APC = 4.91%; p < 0.01) and Poliomyelitis (APC = 3.55%; p < 0.01). We identified an increase of 52.54% in the proportion of municipalities in Maranhão from 2015 to 2021. with extremely high (p = 0.025) and high (p = 0.028) RTVPD. The PNI indicators deteriorated. reaffirming the susceptibility to the emergence of vaccine-preventable diseases.

Abstract
Objective To compare hospital mortality rates (HMR) due to severe acute respiratory syndrome (SARS) associated with COVID-19 recorded in metropolitan areas and other regions (interior) of Brazil in 2020 and 2021. Method This ecological study used public data available on OpenDataSUS. The information was accessed in May 2022. The following variables were considered: age, sex, hospitalization, presence of a risk factor, ICU stay, use of ventilatory support, and final classification in the individual registration form of SARS cases due to COVID-19. Cases and deaths were stratified into five age groups (0-19 years, 20-39 years, 40-59 years, 60-79 years, and ≥80 years) and by place of residence (metropolitan area or interior). The HMR had as numerator the absolute number of deaths by SARS associated with covid-19; and, as a denominator, the absolute number of cases of SARS due to covid-19 according to the year of occurrence, area of residence, age bracket, sex, hospitalization, presence of a risk factor, ICU admission, and use of ventilatory support. Results There was a significant increase in HMR due to SARS associated with COVID-19 in 2021 in all age groups, except 0-19 years and ≥80 years, as well as among individuals admitted to an ICU and who used invasive ventilatory support, both in metropolitan areas as well as in the interior. Conclusions There was a worsening of the epidemiological scenario in 2021 with an increase in HMR. However, no differences were identified between the metropolitan regions and the interior of the country.

Abstract
The drop in childhood vaccination coverage (VC), including poliomyelitis, has become a health concern. The objective was to analyze the temporal trend of coverage of the three doses of the polio vaccine in the first 12 months of life between 2011 and 2021, in addition to mapping vaccination coverage in Brazil, including the COVID-19 pandemic period. An ecological study was carried out using interrupted time series (STI) techniques and spatial analysis, with data from the National Immunization Program Information System. The VC trend was adjusted by the Newey-West variance estimator according to the federated units and the Brazilian Deprivation Index. The VC distribution was estimated by Bayesian models and the spatial clusters by the global and local Moran index, identifying areas of lower coverage in the health regions. There was a reduction in the VC over the period in all regions, being more pronounced in the North and Northeast regions and during the Covid-19 pandemic. The biggest drops were identified in states and health regions with greater social vulnerability after 2019. The drop in VC shows that the risk of reintroduction of the wild virus is imminent and the challenges need to be faced with the strengthening of the Brazilian Health System (SUS).

Abstract
Objective To assess the effect of coverage of the Bolsa Família Program (BFP) on oral cancer mortality rates in Brazil between 2005 and 2017, adjusting for health care coverage and socioeconomic characteristics of the Brazilian federative units. Methods This is an ecological study using annual data (2005-2017) from all the Brazilian federative units. The dependent variable for this study was the oral cancer mortality rate, standardized by gender and age using the direct standardization technique. BFP coverage was the main independent variable, calculated as the ratio of the number of BFP beneficiaries to those families that should potentially be entitled to this conditional cash transfer. Socioeconomic background and health care coverage were covariables. Choropleth maps were drawn, and space-time cube analysis was used to assess changes in the spatiotemporal distribution of BFP and oral cancer mortality rates. Mixed-effects linear regression analysis estimated the coefficients (β) and 95% confidence intervals (CI) for the association between BFP coverage and oral cancer mortality rates. Results BFP coverage trends increased and oral cancer mortality rate trends stabilized in Brazilian federative units, except for Maranhão, Goiás, and Minas Gerais, where the oral cancer mortality rates have increased. In the adjusted model, greater BFP coverage was associated with lower oral cancer mortality rates (β -2.10; 95% CI [-3.291, -0.919]). Conclusions Egalitarian strategies such as BFP can reduce the oral cancer mortality rate. We recommend the follow-up of families benefiting from conditional cash transfer program by oral health teams to reduce the oral cancer mortality rate.

Rev Panam Salud Publica 2022; 46:e63. [PMID: 36060205 PMCID: PMC9426956 DOI: 10.26633/rpsp.2022.63] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 10/28/2021] [Indexed: 11/24/2022] Open
Abstract
Objective To investigate whether structural aspects of primary care units (PCUs) and the work processes of primary care teams are associated with the rate of hospitalizations for primary care-sensitive conditions (HPCSC) in children younger than 5 years of age in Brazil. Method For this longitudinal ecological study, secondary data were obtained from the Brazilian Hospital Information System and from three cycles of the National Program for Access and Quality Improvement in Primary Care (PMAQ-AB) (2012, 2014, 2017/2018). The analysis included 42 916 PCUs. A multilevel random intercept model with fixed slope was used. In the first level, the outcome (HPCSC rates) and explanatory variables (structure and process indicators) aggregated by PCU were analyzed. Social determinants (represented by a stratification criterion combining municipality population and health care management indicators) were entered in the second level. The t test with Bonferroni correction was used to compare indicator means between regions, and multilevel linear regression was used to estimate the correlation coefficients. Results The HPCSC rate in children younger than 5 years was 62.78/100 thousand population per estimated PCU coverage area. A direct association with the outcome was observed for: participation in one or more PMAQ-AB cycles; team planning; special hours; dedicated pediatric care area; and availability of vaccines. Equipment, materials, supplies, and being a small or medium-size municipality were inversely associated with HPCSC. Conclusions HPCSC rates in children below 5 years of age may potentially be reduced through improvements in PCU structure and process indicators and in municipal social determinants.

Abstract
This study aimed to develop an intelligible scale to measure the level of supply of best practices in labor, childbirth and delivery in maternity units in the Rede Cegonha (RC) based on the workers' perception. The scale consisted of seventeen items related to best practices, based on the instrument used in the "Evaluation of care during delivery and birth in maternity hospitals in the RC" research The three-parameter logistic model of Item Response Theory was used to create the scale and analyze the items. The scale consisted of three levels. In the first level, there are maternity hospitals that adequately offered strategies for welcoming and encouraging the pregnant woman to circulate during labor. The second level maternity wards also included the adequate offer of the right to a companion of choice, massage, ball and different birth positions. Finally, the third level maternity hospitals also offered an adequate delivery stool, as well as the items already mentioned. The findings of this study showed the contribution of each item in measuring the level of supply of best practices in care for labor, childbirth and delivery and the construction of an intelligible scale to assess RC maternity hospitals.

Abstract
RESUMO O objetivo do estudo foi identificar desigualdades macrorregionais relacionadas à estrutura e ao processo de trabalho para o atendimento do Diabetes Mellitus (DM) na Atenção Primária à Saúde (APS) ao longo dos três ciclos do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) no Brasil. Trata-se de um estudo ecológico, longitudinal, de abrangência nacional, com dados secundários dos três ciclos do PMAQ-AB. Os dados foram comparados entre as macrorregiões brasileiras utilizando o teste t com a correção de Bonferroni. As regiões Norte e Nordeste apresentaram os menores percentuais de adequação nos itens de estrutura: dependências da unidade (<74%), acessibilidade ao cadeirante (<63%), horário especial de funcionamento (<16%), equipe ampliada (<12%) e insumos (<89%) em todos os ciclos do PMAQ-AB, quando comparadas às demais regiões. Já os itens relacionados ao processo de trabalho apresentaram pouca variação entre as regiões, e os que apresentaram percentuais médios ≤ 75% de adequação foram: agenda especializada (41%, 33%, 41%), apoio matricial (58%, 72%, 70%), oferta e resolubilidade de ações (62%, 64%, 75%) e educação permanente (35%, 42%, 58%). Ainda existe a necessidade de investimentos na estrutura e em melhorias no processo de trabalho das equipes, principalmente nas macrorregiões Norte e Nordeste.

Abstract
The objective was to estimate the proportion of women with a full-time companion in Brazilian maternities linked to the Rede Cegonha (RC) and to compare them between the macro-regions in Brazil. A nationwide study, carried out from December/2016 to October/2017. 10,665 puerperal women from all regions of Brazil participated in the study, who gave birth at one of 606 maternity hospitals with a regional action plan approved by RC. Proportions and respective 95% confidence intervals were estimated, adjusted for the cluster effect, by comparing the macro-regions using Wald's chi-square test. The presence of a full-time companion occurred in 71.2% of maternities, being higher among women aged 20-35 years, brown-skinned, with higher education, married, and assisted in vaginal delivery. Almost 30% of puerperal women did not have a full-time companion. In the Southeast and Midwest regions, self-declared black women, with less schooling and unmarried women were less accompanied. The moment of delivery had less presence of the companion (29.2%). Despite the advances, this right is still not fully fulfilled, pointing to the occurrence of social inequities among Brazilian macro-regions.

Abstract
ABSTRACT This study aimed to identify macro-regional structure and work process inequalities for Diabetes Mellitus (DM) treatment in Primary Health Care (PHC) throughout the three cycles of the National Program for Access and Quality Improvement of Primary Care (PMAQ-AB) in Brazil. This ecological, longitudinal, nationwide study employed secondary data from the three PMAQ-AB cycles. The data were compared between the Brazilian macro-regions using the t-test with Bonferroni correction. The North and Northeast had the lowest percentages of adequacy in the structure items: unit premises (<74%), wheelchair user accessibility (<63%), special opening hours (<16%), expanded teams (<12%), and supplies (<89%) in all PMAQ-AB cycles when compared to other regions. The items related to the work process barely varied between regions, and those with mean adequacy percentages ≤ 75% were specialized agenda (41%, 33%, 41%), matrix support (58%, 72%, 70 %), offer and resolution of actions (62%, 64%, 75%) and continuing education (35%, 42%, 58%). Investments are still required in the structure and improvement in the teams’ work process, especially in the North and Northeast macro-regions.

Abstract
OBJECTIVE To analyse the provision of oral cancer (OC) care services in the Dental Specialties Centers (Centros de Especialidades Odontológicas-CEO) in Brazil and identify changes over two cycles of external evaluation of the Program for the Improvement of Access and Quality-PMAQ, in 2014 and 2018. METHOD This is a nationwide panel ecological study, including 916 CEO. Data from interviews with managers and dentists of the CEO were used, including variables related to training on OC, clinical protocols, biopsies, referral for diagnosis and treatment, and registration of users with OC. We carried out Latent Transition Analysis (LTA) to identify patterns (latent status LS) of service adequacy and work processes' changes between the two assessment cycles. We tested models with three, four, and five LS, selecting the one with the best conceptual interpretability and good model fit parameters. Data from the LS were plotted on choropleth and hotspots maps in Brazil allowing us to identify areas with the better or worse provision of specialized OC services. RESULTS The model with four LS was chosen. The four LS were named: 1.'Most indicators inadequate for OC care' (the worst); 2. 'Most indicators suitable for OC care' (the best); 3. 'CEO with a poor relation with Primary Health Care (PHC) services'; and 4. 'CEO with a poor relation with tertiary hospital services'. The comparison of the LS transition between the two cycles revealed that 419 (45.7%) CEO remained in the same LS (1→1, 3→4, 2→2); 228 (24.9%) switched to a worse status (2→1, 2→4, 3→1) and 269 (29.4%) switched to a better LS (1→2, 1→4, 3→2). While the majority of the CEO improved, we identified a decline of 17.8% in those who reported performing biopsies and 18.3% in the number of CEO that had hospitals for referring confirmed OC cases. Almost all Brazilian states had CEO that improved the work process. The Southeast and South regions had the highest percentage of CEO with the better work process in both cycles. Hotspots showed areas concentrating improvements in the work process in the Northeast region. However, some hotspots in the North revealed some CEO where the work process deteriorated or remained unsatisfactory. CONCLUSIONS There are regional inequities in the provision of OC care in CEO. Most services improved their work process or remained stable. However, the biopsies and the referral to hospital care for confirmed cases declined, indicating that CEO need to improve planning and care provision to reduce OC morbimortality.

Abstract
OBJECTIVE To identify changes in the dental service provision to people with disabilities (PD) in the Dental Specialties Centers (acronym CEO in Portuguese-Centro de Especialidades Odontológicas) between the first and second cycles of the Program for the Improvement of Access and Quality of CEO and analyse factors associated with any changes. METHODS This nationwide ecological time series study adopted the CEO as the analysis unit. The 827 CEO who participated in the two program's cycles (2014 and 2018) were included. Data on the structure and the work process were considered to identify features of providing services to PD in both cycles. Latent transition analysis (LTA) was performed to identify latent status (LS) with similar features and model the transition between LS over time. Models with five variables and with two to five LS were tested, considered best conceptual interpretability and best model fit parameters: human resources structure (dentist working exclusively with PD) and work process that identified guarantee of PD treatment at the CEO, the CEO's interface with primary care, and the interface with tertiary care. Spatial analysis was performed to identify spatial patterns of LS in the Brazilian territory with choropleth maps. A multinomial logistic regression model was performed to identify factors associated with changes in the provision of CEO (improved, remained or worsened). FINDINGS The best-fit model identified four LS: 'Better', 'Medium better', 'Medium worse' and 'Worse'. CEO remained in the LS 'Better' (94%), LS 'Medium' (5.3%) and LS 'Worse' (78.4%). It is noteworthy that the highest proportion of CEO, in both cycles, was in the LS 'Better', featured by the CEO, characterized by all the CEO guaranteeing treatment to users with PD, high proportions of professionals working exclusively with PD, and most CEO articulated with primary care and with tertiary care. However, there is a decrease in the number of postgraduate professionals specializing in this service profile (1.3%). The higher the population growth, the greater the likelihood of the CEO achieving 'improved' in the LS. Moreover, the higher the number of goals, the lower the likelihood of the CEO getting 'worse' in the LS. CONCLUSION Advances in dental service provision were observed, with more significant transitions to the 'Better' class, with improvements mainly in the interface with primary and tertiary care. Disability will be an even more significant concern as the population ages. Initiatives that can remove barriers and empower PD are potent in the provision of oral health services.

Abstract
This study sought to analyze the correlation of the quality of Primary Health Care services in reducing child mortality, via geoprocessing. It involved an ecological study, with a cross-sectional approach, in which secondary data from all 5,565 Brazilian municipalities were used to analyze the infant mortality rate (IMR) and cause of infant death. The data related to IMR was obtained from the Mortality Information System. For the spatial analysis, 5,011 municipalities were included. The clustering analyses were performed using GEODA software and the spatial regression analyses were performed using ARCGIS 10.5 software. In Brazil, there was a 45.07% reduction in IMR between the years 2000 and 2015. The greatest reduction occurred in the northeastern region of the country, although it is still the region with the highest IMR. Of the 749 municipalities analyzed in the differential cluster for infant death, 153 had high IMR. The areas with the greatest increase in IMR were found in the North and Northeast regions. In Brazil, IMR proved to be inversely associated with the accessibility to high complexity services, health management strata and population size, reference for childbirth, live birth rate, per capita income and unemployment rate. A progressive reduction in IMR was recorded between 2000 and 2015.

OBJECTIVE To estimate the 2020 all-cause and COVID-19 excess mortality according to sex, age, race/color, and state, and to compare mortality rates by selected causes with that of the five previous years in Brazil. METHODS Data from the Mortality Information System were used. Expected deaths for 2020 were estimated from 2015 to 2019 data using a negative binomial log-linear model. RESULTS Excess deaths in Brazil in 2020 amounted to 13.7%, and the ratio of excess deaths to COVID-19 deaths was 0.90. Reductions in deaths from cardiovascular diseases (CVD), respiratory diseases, and external causes, and an increase in ill-defined causes were all noted. Excess deaths were also found to be heterogeneous, being higher in the Northern, Center-Western, and Northeastern states. In some states, the number of COVID-19 deaths was lower than that of excess deaths, whereas the opposite occurred in others. Moreover, excess deaths were higher in men aged 20 to 59, and in black, yellow, or indigenous individuals. Meanwhile, excess mortality was lower in women, in individuals aged 80 years or older, and in whites. Additionally, deaths among those aged 0 to 19 were 7.2% lower than expected, with reduction in mortality from respiratory diseases and external causes. There was also a drop in mortality due to external causes in men and in those aged 20 to 39 years. Moreover, reductions in deaths from CVD and neoplasms were noted in some states and groups. CONCLUSION There is evidence of underreporting of COVID-19 deaths and of the possible impact of restrictive measures in the reduction of deaths from external causes and respiratory diseases. The impacts of COVID-19 on mortality were heterogeneous among the states and groups, revealing that regional, demographic, socioeconomic, and racial differences expose individuals in distinct ways to the risk of death from both COVID-19 and other causes.

Microplanning for designing vaccination campaigns in low-resource settings: A geospatial artificial intelligence-based framework. Vaccine 2021; 39:6276-6282. [PMID: 34538526 PMCID: PMC8496523 DOI: 10.1016/j.vaccine.2021.09.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 08/30/2021] [Accepted: 09/03/2021] [Indexed: 11/30/2022]
Abstract
Existing campaign-based healthcare delivery programs used for immunization often fall short of established health coverage targets due to a lack of accurate estimates for population size and location. A microplan, an integrated set of detailed planning components, can be used to identify this information to support programs such as equitable vaccination efforts. Here, we presents a series of steps necessary to create an artificial intelligence-based framework for automated microplanning, and our pilot implementation of this analysis tool across 29 countries of the Americas. Further, we describe our processes for generating a conceptual framework, creating customized catchment areas, and estimating up-to-date populations to support microplanning for health campaigns. Through our application of the present framework, we found that 68 million individuals across the 29 countries are within 5 km of a health facility. The number of health facilities analyzed ranged from 2 in Peru to 789 in Argentina, while the total population within 5 km ranged from 1,233 in Peru to 15,304,439 in Mexico. Our results demonstrate the feasibility of using this methodological framework to support the development of customized microplans for health campaigns using open-source data in multiple countries. The pandemic is demanding an improved capacity to generate successful, efficient immunization campaigns; we believe that the steps described here can increase the automation of microplans in low resource settings.

Autoregressive spatial modeling of possible cases of dengue, chikungunya, and Zika in the capital of Northeastern Brazil. Rev Soc Bras Med Trop 2021; 54:e0223. [PMID: 34586289 PMCID: PMC8463031 DOI: 10.1590/0037-8682-0223-2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 08/06/2021] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION: Dengue, chikungunya, and Zika are a growing global health problem. This study analyzed the spatial distribution of dengue, chikungunya, and Zika cases in São Luís, Maranhão, from 2015 to 2016 and investigated the association between socio-environmental and economic factors and hotspots for mosquito proliferation. METHODS: This was a socio-ecological study using data from the National Information System of Notifiable Diseases. The spatial units of analysis were census tracts. The incidence rates of the combined cases of the three diseases were calculated and smoothed using empirical local Bayes estimates. The spatial autocorrelation of the smoothed incidence rate was measured using Local Moran's I and Global Moran's I. Multiple linear regression and spatial autoregressive models were fitted using the log of the smoothed disease incidence rate as the dependent variable and socio-environmental factors, demographics, and mosquito hotspots as independent variables. RESULTS: The findings showed a significant spatial autocorrelation of the smoothed incidence rate. The model that best fit the data was the spatial lag model, revealing a positive association between disease incidence and the proportion of households with surrounding garbage accumulation. CONCLUSIONS: The distribution of dengue, chikungunya, and Zika cases showed a significant spatial pattern, in which the high-risk areas for the three diseases were explained by the variable "garbage accumulated in the surrounding environment,” demonstrating the need for an intersectoral approach for vector control and prevention that goes beyond health actions.

Abstract
AIM To assess the prevalence of temporomandibular disorder (TMD) in adolescents and estimate possible associations with poverty. BASIC RESEARCH DESIGN A cross-sectional study nested within a prospective birth cohort study conducted in São Luís, Maranhão, Brazil. PARTICIPANTS 2,412 adolescents aged 18-19 years. MATERIAL AND METHODS The presence of TMD, classified according to the Fonseca Anamnestic Index, was used as the outcome. The following explanatory variables were assessed: gender, household head, paved/asphalted street, piped water, and socioeconomic background, based on the Brazilian Association of Market Research criteria and the poverty income ratio (PIR). Logistic regression analysis was performed with the estimation of odds ratios (OR) and 95% confidence intervals. RESULTS TMD was common (51.4%) and was associated with poverty, as it was more frequent among adolescents from social classes D-E (OR=2.60; 95% CI: 1.48-4.55) and C (OR=1.82; 95% CI: 1.12-2.99) compared to A/B, and among poor adolescents using the PIR (OR=1.50; 95% CI: 1.02-2.33). CONCLUSIONS The prevalence of TMD in socioeconomically disadvantaged adolescents in São Luís is high, and these data allow the early identification of at-risk groups. We recommend carrying out other population-based studies, using diagnostic strategies with greater accuracy.

Abstract
Background Preterm birth (PTB) is a growing health issue worldwide, currently considered the leading cause of newborn deaths. To address this challenge, the present work aims to develop an algorithm capable of accurately predicting the week of delivery supporting the identification of a PTB in Brazil. Methods This a population-based study analyzing data from 3,876,666 mothers with live births distributed across the 3,929 Brazilian municipalities. Using indicators comprising delivery characteristics, primary care work processes, and physical infrastructure, and sociodemographic data we applied a machine learning-based approach to estimate the week of delivery at the point of care level. We tested six algorithms: eXtreme Gradient Boosting, Elastic Net, Quantile Ordinal Regression - LASSO, Linear Regression, Ridge Regression and Decision Tree. We used the root-mean-square error (RMSE) as a precision. Findings All models obtained RMSE indexes close to each other. The lower levels of RMSE were obtained using the eXtreme Gradient Boosting approach which was able to estimate the week of delivery within a 2.09 window 95%IC (2.090-2.097). The five most important variables to predict the week of delivery were: number of previous deliveries through Cesarean-Section, number of prenatal consultations, age of the mother, existence of ultrasound exam available in the care network, and proportion of primary care teams in the municipality registering the oral care consultation. Interpretation Using simple data describing the prenatal care offered, as well as minimal characteristics of the pregnant, our approach was capable of achieving a relevant predictive performance regarding the week of delivery. Funding Bill and Melinda Gates Foundation, and National Council for Scientific and Technological Development - Brazil, (Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPQ acronym in portuguese) Support of the research project named: Data-Driven Risk Stratification for Preterm Birth in Brazil: Development of a Machine Learning-Based Innovation for Health Care- Grant: OPP1202186.

Vaccination services and incomplete vaccine coverage for children: a comparative spatial analysis of the BRISA cohorts, São Luís (Maranhão State) and Ribeirão Preto (São Paulo State), Brazil. CAD SAUDE PUBLICA 2021; 37:e00037020. [PMID: 34190749 DOI: 10.1590/0102-311x00037020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 09/04/2020] [Indexed: 11/22/2022] Open
Abstract
We analyzed the spatial relation between incomplete vaccine coverage for children and the distance from vaccination services. This was a cross-sectional study of children from 13 to 35 months of age from the cities of São Luís (Maranhão State) and Ribeirão Preto (São Paulo State), Brazil, and from basic health units (UBS, in Portuguese). The sample consisted of 2,744 children from São Luís and 3,325 from Ribeirão Preto. Data about incomplete vaccine coverage for children were obtained from the BRISA birth cohorts. Data about the quality of UBS vaccination services were obtained from the first cycle of the Brazilian National Program for Improvement of Access and Quality of Basic Care (PMAQ-AB, in Portuguese). For the spatial analysis, we determined the distance between the residence of the children (with and without a complete vaccine calendar) and the vaccination services of the UBS (classified according to number of structural items). Incomplete vaccine coverage was more pronounced in São Luís, with greater percentages for human rotavirus and triple viral vaccines, with the latter being the least available. In Ribeirão Preto, incomplete BCG vaccine coverage was more pronounced, with the tetravalent vaccine being the least available. Children from the two cities showed similarities: most of them had adult mothers with 9 to 11 years of schooling and did not reside with siblings in the household. They also showed differences: in São Luís, most mothers belonged to the economic class C, while in Ribeirão Preto they belong to the A and B classes. In the two cities with different socioeconomic conditions, complete vaccine coverage seemed not to depend on the location or quality of the vaccination service. Although São Luís showed a better structure of the services, incomplete vaccine coverage was higher compared to Ribeirão Preto.

Abstract
This study aimed to identify the structuring elements guiding the establishment of the social representations of diabetic foot among people with diabetes mellitus. This qualitative study is based on the Social Representations Theory and was conducted in a capital of the Brazilian Northeast. The free word association test and a roadmap were used to characterize the sociodemographic and clinical profile to collect data. The analysis was performed using openEVOC software. The constituent elements of the diabetic foot's social representation "cure" and "really bad", revealing that living with a diabetic foot is challenging, but there is hope for a cure, which is a driving force in the daily search for care. The "prevention" element emerged in the representational field, denoting a more critical view and a capacity to transform the identified core elements. We found that the representational structure is based on subjective, valuating, and attitudinal contents. This knowledge can contribute to the design of interventions in the provision of care and diabetic foot screening in PHC services.

Abstract
The scope of this article is to compare the assessment of users of health services who participated in the PMAQ-AB on child health in the states of the Brazilian Northeast. It is a cross-sectional study conducted with secondary data based on interviews with 5,116 users of 4,190 Family Health Teams in the nine states of the Northeast macroregion. Fourteen questions on the medical monitoring of children from 0 to 2 years old were evaluated. Proportions and 95% confidence intervals were calculated for each Unit of the Federation of the Brazilian Northeast. The indicators with the highest proportions were the Guthrie PKU test performed within seven days of life (84.4%), children always accompanied by the same professionals (79.1%), monitoring expected growth and development for age (84.9%), dietary guidance (86.3%) and up-to-date vaccination (95.3%). The indicators with the lowest proportions were guidance on the best position for the child to sleep in (45.7%) and whether or not the child's health handbook (46.9%) was received. In all indicators, there were significant differences between the states analyzed. There are differences in the quality of child health care on offer according to the evaluation of users participating in the PMAQ-AB between states in the Northeast.

Abstract
BACKGROUND Beriberi is the clinical manifestation of thiamine deficiency. It is multicausal and typically associated with poverty and food insecurity among vulnerable populations, such as indigenous people. OBJECTIVE The objective of this study was to carry out a spatial analysis of reported cases of beriberi among indigenous people in Brazil. METHODS Cross-sectional study using time series data on suspected cases of beriberi reported to the Ministry of Health via the FormSUS between July 2013 and September 2018. Indigenous villages were georeferenced, and Kernel density estimation was used to identify patterns of the spatial distribution of beriberi cases. RESULTS A total of 414 cases of beriberi were reported in the country of which 210 (50.7%) were indigenous people. All the cases in indigenous people occurred in states located in the Legal Amazon (Maranhão, Roraima, and Tocantins). Kernel density estimation showed high-density areas in Tocantins and Roraima. CONCLUSIONS This is the first nationwide study of reported cases of beriberi. The findings can be used to guide actions that contribute to the monitoring and prevention of beriberi among indigenous people.

Abstract
OBJECTIVES To estimate the prevalence and factors associated with hesitancy in getting the vaccine against SARS-CoV-2 in Maranhão, Brazil. METHODS This is a cross-sectional population-based study conducted from October 19 to 30, 2020. The estimates were calculated based on clustering, stratification, and non-response. A three-stage sampling was adopted, considering stratum, census tracts, and domicile. After systematic analysis, thirty sectors were selected in each stratum, totaling 150 sectors. Each sector contained a fixed number of 34 households, thus totaling 5,100 households. One individual within each household (resident for at least six months and aged one year or more) was selected by a simple random sampling. We questioned participants about their vaccination intention. Univariate association between independent variables and the outcome were verified using descriptive analysis (weighted frequencies) and Pearson's chi-square test (p < 0.05). Robust multivariate analysis was performed using a three-level hierarchical model. RESULTS We found 17.5% (95%CI 16.1-19.1%) of the 4,630 individuals interviewed to report hesitancy to be vaccinated against covid-19. After final model adjustment, vaccination hesitancy was statistically higher among residents of the cities of Imperatriz (24.0%; RP = 1.48; IC95% 1.09-2.02) and municipalities of the Grande Ilha de São Luís (20.7%; RP = 1.34; 95%CI 1.02-1.76), female individuals (19.8%; RP = 1.44; 95%CI 1.20-1.75), older adults (22.8%; RP = 1.79; IC95% 1.30-2.46), evangelicals (24.1%; RP = 1.49; 95%CI 1.24-1.79), and those without reported symptoms (18.6%; RP = 1.24; 95%CI 1.02-1.51). We found no statistical differences for other socioeconomic and demographic characteristics, as well as variables related to the labor market, behaviors, and health conditions of the interviewees. CONCLUSION The prevalence of vaccine hesitancy in Maranhão and its association with individual, contextual, and clinical factors enable us to identify the groups and contexts of greatest resistance, requiring special attention from public strategies to ensure wide vaccination.

Abstract
This study aimed to analyze the association of socioeconomic factors with the prevalence of dental caries in adolescents from São Luís, Maranhão, Brazil, to answer whether social inequalities persist in distributing this disease. This is a cross-sectional study nested in a prospective cohort. We included 2,413 adolescents aged 18-19 years evaluated in the 2016 second follow-up. The outcome was teeth with untreated dental caries (yes or no) assessed by the DMFT index. Socioeconomic and demographic characteristics were the independent variables. Descriptive statistical and Poisson regression analyses were performed, calculating crude and adjusted prevalence ratios (PRs) (alpha=5%). Belonging to economic classes C (PR=1.23; 95% CI: 1.11-1.37) or D-E (PR=1.48; 95% CI: 1.32-1.65), being married/living with a partner (PR=1.22; 95% CI: 1.07-1.39), having separated parents (PR=1.11; 95% CI 1.03-1.19) and a greater number of people in the household (PR=1.05; 95% CI: 1.03-1.07) were associated with a higher prevalence of dental caries. Social inequalities in adolescent oral health persist despite the implementation of the National Oral Health Policy. The current health care model should seek to reorient health education strategies, targeting them at vulnerable populations.

Abstract
OBJECTIVE Compared indicators of potential access to oral health services sought in two cycles of the Program for Improvement of Access and Quality of Primary Care (PMAQ-AB), verifying whether the program generated changes in access to oral health services. METHODS Transitional analysis of latent classes was used to analyze two cross-sections of the external evaluation of the PMAQ-AB (Cycle I: 2011-2012 and Cycle II: 2013-2014), identifying completeness classes for a structure and work process related to oral health. Consider three indicators of structure (presence of a dental surgeon, existence of a dental office and operating at minimum hours) and five of the work process (scheduling every day of the week, home visits, basic dental procedures, scheduling for spontaneous demand and continuation of treatment). Choropleth maps and hotspots were made. RESULTS The proportion of elements that had one or more dentist (CD), dental office and operated at minimum hours varied from 65.56% to 67.13 between the two cycles of the PMAQ-AB. The number of teams that made appointments every day of the week increased 8.7% and those that made home visits varied from 44.51% to 52.88%. The reduction in the number of teams that reported guaranteeing the agenda for accommodating spontaneous demand, varying from 62.41% to 60.11% and in the continuity of treatment, varying from 63.41% to 61.11%. For the structure of health requirements, the predominant completeness profile was "Best completeness" in both cycles, comprising 71.0% of the sets at time 1 and 67.0% at time 2. The proportion of teams with "Best completeness" increased by 89.1%, the one with "Worst completeness" increased by 20%, while those with "Average completeness" decreased by 66.3%. CONCLUSION We identified positive changes in the indicators of potential access to oral health services, expanding the users' ability to use them. However, some access attributes remain unsatisfactory, with organizational barriers persisting.

Abstract
OBJECTIVE To assess the structure of primary health care centers (PHCCs) and the work process of primary care teams in child care in Brazil. METHODS This was an ecological study with data from the three cycles of the Program for Primary Health Care Access and Quality Improvement 2012-2018, by states and regions. Seven structural and thirteen procedural indicators were analyzed. Student's t-test was used to compare indicator averages between regions. RESULTS 85,845 teams participated in the three cycles of the program, grouped into 68,320 PHCCs. In the last evaluation cycle (2017-2018), mean percentage adequacy rates were higher among the structure indicators: health center operation (99%), equipment/materials (82%), vaccine availability (74%) and medication dispensing (70%). Population without coverage (68%) and making appointments with specialists (52%) corresponded to the lowest percentages of adequacy of process indicators. CONCLUSION Process indicators had higher levels of adequacy than structure indicators.

Abstract
OBJECTIVE To estimate the seroprevalence of SARS-CoV-2 in the state of Maranhão, Brazil. METHODS A population-based household survey was performed, from July 27, 2020 to August 8, 2020. The estimates considered clustering, stratification and non-response. Qualitative detection of IgM and IgG antibodies was performed in a fully-automated Elecsys® Anti-SARS-CoV-2 electrochemiluminescence immunoassay on the Cobas® e601 analyzer (Roche Diagnostics). RESULTS In total, 3,156 individuals were interviewed. Seroprevalence of total antibodies against SARS-CoV-2 was 40.4% (95%CI 35.6-45.3). Population adherence to non-pharmaceutical interventions was higher at the beginning of the pandemic than in the last month. SARS-CoV-2 infection rates were significantly lower among mask wearers and among those who maintained social and physical distancing in the last month compared to their counterparts. Among the infected, 26.0% were asymptomatic. The infection fatality rate (IFR) was 0.14%, higher for men and older adults. The IFR based on excess deaths was 0.28%. The ratio of estimated infections to reported cases was 22.2. CONCLUSIONS To the best of our knowledge, the seroprevalence of SARS-CoV-2 estimated in this population-based survey is one of the highest reported. The local herd immunity threshold may have been reached or might be reached soon.

Abstract
OBJECTIVE: To estimate the effect of being a beneficiary of the Bolsa Família Program (BFP) in the vaccination of children aged 13 to 35 months. METHODS: Our study was based on all birth records of residents of Ribeirão Preto (SP) and probabilistic sampling with 1/3 of the births of residents of São Luís (MA), selecting low-income children, born in 2010, belonging to the cohorts Brazilian Ribeirão Preto and São Luís Birth Cohort Studies and eligible for the Bolsa Família program. The information of Cadastro Único (CadÚnico – Single Registry) was used to categorize the receipt of benefit from the BFP (yes or no). The final sample consisted of 532 children in Ribeirão Preto and 1,229 in São Luís. The outcome variable was a childhood vaccine regimen, constructed with BCG, tetravalent, triple viral, hepatitis B, poliomyelitis, rotavirus and yellow fever vaccines. The adjustment variables were: economic class, mother's schooling and mother's skin color. Children with monthly per capita family income of up to R$ 280.00 and/or economic class D/E were considered eligible for the benefit of the BFP. A theoretical model was constructed using a directed acyclic graph to estimate the effect of being a beneficiary of the BFP in the vaccination of low-income children. In the statistical analyses, weighing was used by the inverse of the probability of exposure and pairing by propensity score. RESULTS: Considering a monthly per capita family income of up to R$ 280.00, being a beneficiary of the BFP had no effect on the childhood vaccination schedule, according to weighing by the inverse of the probability of exposure (SL-coefficient: −0.01; 95%CI −0.07 to 0.04; p = 0.725 and RP-coefficient: 0.04; 95%CI −0.02 to 0.10; p = 0.244) and pairing by propensity score (SL-coefficient: −0.01; 95%CI −0.07 to 0.05; p = 0.744 and RP-coefficient: 0.04; 95%CI −0.02 to 0.10; p = 0.231). CONCLUSIONS: The receipt of the benefit of the BFP did not influence childhood vaccination, which is one of the conditionalities of the program. This may indicate that this conditionality is not being adequately monitored.

Comprehending the lack of access to maternal and neonatal emergency care: Designing solutions based on a space-time approach. PLoS One 2020; 15:e0235954. [PMID: 32702067 PMCID: PMC7377445 DOI: 10.1371/journal.pone.0235954] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Accepted: 06/26/2020] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE The objective of this study was to better understand how the lack of emergency child and obstetric care can be related to maternal and neonatal mortality levels. METHODS We performed spatiotemporal geospatial analyses using data from Brazilian municipalities. An emergency service accessibility index was derived using the two-step floating catchment area (2SFCA) for 951 hospitals. Mortality data from 2000 to 2015 was used to characterize space-time trends. The data was overlapped using a spatial clusters analysis to identify regions with lack of emergency access and high mortality trends. RESULTS From 2000 to 2015 Brazil the overall neonatal mortality rate varied from 11,42 to 11,71 by 1000 live births. The maternal mortality presented a slightly decrease from 2,98 to 2,88 by 100 thousand inhabitants. For neonatal mortality the Northeast and North regions presented the highest percentage of up trending. For maternal mortality the North region exhibited the higher volume of up trending. The accessibility index obtained highlighted large portions of the rural areas of the country without any coverage of obstetric or neonatal beds. CONCLUSIONS The analyses highlighted regions with problems of mortality and access to maternal and newborn emergency services. This sequence of steps can be applied to other low and medium income countries as health situation analysis tool. SIGNIFICANCE STATEMENT Low and middle income countries have greater disparities in access to emergency child and obstetric care. There is a lack of approaches capable to support analysis considering a spatiotemporal perspective for emergency care. Studies using Geographic Information System analysis for maternal and child care, are increasing in frequency. This approach can identify emergency child and obstetric care saturated or deprived regions. The sequence of steps designed here can help researchers, and policy makers to better design strategies aiming to improve emergency child and obstetric care.

Abstract
There are no nationwide studies characterizing accessibility for people with disabilities during delivery. This study aimed to describe the physical structure of hospital units regarding accessibility for pregnant and puerperae with motor (MD), visual (VD), or hearing (HD) disabilities in Brazil. This is an ecological, descriptive study conducted in all 606 health facilities linked to the "Rede Cegonha" where deliveries occurred, according to 2015 databases. We performed the descriptive and geospatial analysis and considered the presence of motor accessibility when the establishment had a handrail or elevator ramp, wheelchair-sized doors, and accessible bathroom with bars. We assumed visual accessibility when there was tactile signage on the floor (Braille system or embossed figures) and hearing accessibility when there was signage by texts, pictures, signs, posters, or symbols in the environments. In Brazil, only 26 (4.3%) of the facilities had accessibility for people with MD, 20 (3.3%) for people with VD, and none for HD. Motor accessibility was worse in the North and Northeast of Brazil, and hearing accessibility in the North region. Despite advances in the implementation of the "Rede Cegonha" in Brazil, the facilities' structure is not adapted for women with MD, VD, or HD.

Abstract
This article compares the findings of "Avaliação da Rede Cegonha" (ARC - Stork Network Assessment), an evaluative study on the Rede Cegonha (RC - Stork Network) program, with Nascer no Brasil (NB - Born in Brazil), a national survey on labor and birth, conducted in 2011-12, before the start implementation of RC. ARC was conducted in 2017, in 606 maternity hospitals involved in RC and NB included a sample with national representation of 266 hospitals. In the current analysis, we included the 136 SUS hospitals that participated in both studies, totaling 3,790 and 12,227 puerperal women. We perform comparisons of best practices and interventions in the management of labor and delivery using Pearson's chi-square test for independent samples. The prevalence of best practices was, on average, 150% higher in ARC than in NB, with a greater relative increase in less developed regions, for older, brown and black women and less educated. Regarding interventions, there was an average reduction of 30% between NB and ARC, with a greater relative reduction in less developed regions and less educated women. There was a significant improvement in the scenario of care for labor and childbirth, with a reduction in regional, educational and racial inequalities in access to appropriate technologies, suggesting that the RC intervention was effective.

Abstract
Abstract Objectives: to analyze differences in prevalence and perpetrators of violence against women before and during pregnancy. Methods: this is a cross-sectional study with a sample of 1,446 pregnant women interviewed in 2010 and 2011 in the São Luís municipality (Brazil). Thirteen questions measured psychological, physical and sexual violence in the 12 months before and during pregnancy. Psychological/physical/sexual violence was defined as any type of violence perpetrated against the interviewees. The perpetrators were categorized into intimate partner, other family members, community members, and multiple perpetrators. Differences between violence before and during pregnancy were analyzed by the chi-square test. Results: psychological/physical/sexual and psychological violence were more prevalent during pregnancy than before gestation (p<0.001). Insults, humiliation and intimidation (p<0.05) were more frequently reported during pregnancy. An intimate partner was the most frequent perpetrator. There were no differences in the percentage of moderate and severe forms of physical violence and sexual violence, recurrence of aggressions and perpetrators in both periods (p>0.05). Conclusions: gestation did not protect users of prenatal services in São Luís municipality from psychological, physical and sexual violence. Psychological/physical/sexual and psychological violence were more commonly practiced during pregnancy. The perpetrators of violence in the year before gestation continued to abuse the interviewees during pregnancy

Abstract
OBJECTIVE To evaluate the association among characteristics of primary health care center (PHCC) with hospitalizations for primary care sensitive conditions (PCSC) in Brazil. METHOD In this study, a cross-sectional ecological study was performed. This study analyzed the 27 capitals of Brazil's federative units. Data were aggregated from the following open access databases: National Program for Access and Quality Improvement in Primary Care, the Hospital Information System of Brazilian Unified Health System and Annual Population Census conducted by the Brazilian Institute of Geography and Statistics. Associations were estimated among characteristics of primary care with the number of three PCSC as the leading causes of hospitalization in children under-5 population in Brazil: asthma, diarrhea, and pneumonia. RESULTS In general, PHCC showed limited structural adequacy (37.3%) for pediatric care in Brazil. The capitals in South and Southeast regions had the best structure whereas the North and Northeast had the worst. Fewer PCSC hospitalizations were significantly associated with PHCC which presented appropriate equipment (RR: 0.98; 95%CI: 0.97-0.99), structural conditions (RR: 0.98; 95%CI: 0.97-0.99), and signage/identification of professionals and facilities (RR: 0.98; 95%CI: 0.97-0.99). Higher PCSC hospitalizations were significantly associated with PHCC with more physicians (RR: 1.23, 95%CI: 1.02-1.48), it forms (RR: 1.01, 95%CI: 1.01-1.02), and more medications (RR: 1.02, 95%CI: 1.01-1.03). CONCLUSION Infrastructural adequacy of PHCC was associated with less PCSC hospitalizations, while availability medical professional and medications were associated with higher PCSC hospitalizations.

Abstract
OBJECTIVE To present a methodology for the empirical evaluation of primary health care (PHC) through the construction of digital representations of potential PHC coverage areas. METHODS In this methodological study, potential areas were constructed by combinatorial analysis between census tracts and the location of basic health units with working PHC teams in Brazil. Six rules were used to parameterize the algorithm for the construction of potential areas. Thus, six restrictions were applied to enable the model: the selection of census tracts near the basic health unit; contiguous sectors; mutually exclusive sectors; sectors located in the same municipality of basic health units; sum of 4 500 users per health team in each unit; and volume of population ascribed proportional to the number of PHC teams allocated to the unit. Based on 316 594 census tracts and 39 758 basic health units, a neighborhood matrix was developed. To that matrix, a graph algorithm was applied to test combinations of sectors that simultaneously met the stipulated rules. RESULTS A total of 1 901 114 arcs were defined, connecting 30 351 census tracts, allowing the construction of 26 907 potential areas. Based on these results, intra-municipal analyses can be performed to monitor PHC indicators. Customizable algorithm parameters can be adjusted to accommodate different sets of rules which may be adapted to different countries. CONCLUSIONS The use of geoprocessing approaches creates conditions for the assessment of PHC impact, based on secondary databases at various levels, such as intra-municipal, basic health unit, and even at the team level.

Abstract
INTRODUCTION Tuberculosis (TB) is an infectious and contagious disease caused by Mycobacterium tuberculosis. TB emerged in the 21st century as an unsolved public health problem. This study aimed to analyze the relationship between the characteristics of basic health units (BHUs) and the number of TB cases detected in Maranhão, Brazil. METHODS An ecological, analytical study was conducted using the municipalities in the state of Maranhão as the unit of analysis. Data regarding the number of detected TB cases was obtained from the Sistema de Informação de Agravos de Notificação database, and the characteristics of the BHUs were obtained from the first cycle of data collection for the Program to Improve Access and Quality of Basic Care. The BHU structure was classified as adequate (80%-100%), partially adequate (60%-79%), poorly adequate (40%-59%), or inadequate (<40%) according to the presence of specified items. The number of BHUs per municipality in each adequacy category was estimated. Inflated Poisson regression analysis was performed to estimate the incidence density ratios (IDRs) and the 95% confidence intervals (95% CIs). RESULTS Municipalities with a higher level of BHU adequacy had a higher number of detected TB cases (IDR = 1.61, 95% CI: 1.01-2.60). CONCLUSIONS Better structured health services in primary care may be associated with better detection and/or notification of TB cases.

Is there a fair distribution of the structure of dental services in the capitals of the Brazilian Federative Units? Int J Equity Health 2019; 18:5. [PMID: 30621709 PMCID: PMC6325759 DOI: 10.1186/s12939-018-0899-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Accepted: 11/28/2018] [Indexed: 11/10/2022] Open
Abstract
Background Brazilian Primary Care Facilities (PCF) provide primary care and must offer dental services for diagnosis, prevention, and treatment of diseases. According to a logic of promoting equity, PCF should be better structured in less developed places and with higher need for oral health services. Objective To analyze the structure of dental caries services in the capitals of the Brazilian Federative Units and identify whether socioeconomic factors and caries (need) are predictors of the oral health services structure. Methods This is an ecological study with variables retrieved from different secondary databases, clustered for the level of the federative capitals. Descriptive thematic maps were prepared, and structural equations were analyzed to identify oral health service structure’s predictors (Alpha = 5%). Four models with different outcomes related to dental caries treatment were tested: 1) % of PCF with a fully equipped office; 2) % of PCF with sufficient instruments, and 3) % of PCF with sufficient supplies; 4) % of PCF with total structure. Results 21.6% of the PCF of the Brazilian capitals had a fully equipped office; 46.9% had sufficient instruments, and 30.0% had sufficient supplies for caries prevention and treatment. The four models evidenced proper fit indexes. A correlation between socioeconomic factors and the structure of oral health services was only noted in model 3. The worse the socioeconomic conditions, the lower the availability of dental supplies (standard factor loading: 0.92, P = 0.012). Estimates of total, direct and indirect effects showed that dental caries experience observed in the Brazilian population by SB-Brasil in 2010 did not affect the outcomes investigated. Conclusion Material resources are not equitably distributed according to the socioeconomic conditions and oral health needs of the population of the Brazilian capitals, thus contributing to persistent oral health inequities in the country.

Fez-se uso de dados das coortes de nascimento BRISA, em Ribeirão Preto, São Paulo, e São Luís, Maranhão, Brasil. O início das coortes ocorreu em 2010, com a inclusão de todos os nascimentos em Ribeirão Preto (7.794) e 5.236 em São Luís, abrangendo amostra aleatória de um terço. No seguimento, realizado de 2011 a 2013, retornaram 3.805 crianças em Ribeirão Preto e 3.308 em São Luís. Foram utilizados dados do momento do seguimento, e estes foram integrados às informações do Cadastro Único (CadÚnico). Consideraram-se dois critérios de elegibilidade para o benefício do Bolsa Família: renda familiar per capita mensal de até R$ 140,00 e classe econômica D/E. Estimaram-se percentuais de foco e cobertura do Bolsa Família. Realizou-se ponderação para perdas de seguimento. O foco do Bolsa Família, segundo renda familiar per capita mensal, foi de 33,8% em São Luís e 15,9% em Ribeirão Preto, e de acordo com a classe econômica foi de 33,7% em São Luís e 15,3% em Ribeirão Preto. A cobertura do Bolsa Família, de acordo com o critério de renda familiar per capita mensal, foi de 82,1% em São Luís e 71,6% em Ribeirão Preto; e segundo classe econômica foi de 68,9% em São Luís e 46,8% em Ribeirão Preto. Foram baixos os percentuais de foco e melhores os de cobertura do Bolsa Família, com estimativas destes indicadores maiores para São Luís em relação a Ribeirão Preto.

Abstract
OBJECTIVE to describe a solution enabling geolocation of hospital admissions (AIH), processed on the Brazilian National Health System's Hospital Information System. METHODS in order to spatialize AIHs an R language script was written, based on the microdatasus and CepR packages; the script was applied to identify all AIHs in Goiás state in the year 2015; after downloading and pre-processing the data, the procedure for AIH spatialization was detailed. RESULTS of the 361,213 AIHs processed, we were able to retrieve 24,220 different ZIP codes (CEPs); from this set of ZIP codes, 23,910 (98.7%) were geolocated; these geolocated ZIP codes enabled spatialization of 97.7% of AIHs processed for the state of Goiás. CONCLUSION it is possible to spatialize AIHs with a high success rate; the method detailed in this paper opens a new range of possibilities for the design of evaluation studies, formulation of policies and planning of health care actions.

Abstract
Dengue fever, chikungunya fever, and zika virus infections are increasing public
health problems in the world, the last two diseases having recently emerged in
Brazil. This ecological study employed spatial analysis of probable cases of
dengue fever, chikungunya fever, and zika virus infections reported to the
National Mandatory Reporting System (SINAN) in Maranhao State from 2015 to 2016.
The software GeoDa version 1.10 was used for calculating global and local Moran
indices. The global Moran index identified a significant autocorrelation of
incidence rates of dengue (I=0.10; p=0.009) and zika (I=0.07; p=0.03). The study
found a positive spatial correlation between dengue and the population density
(I=0.31; p<0.001) and a negative correlation with the Performance Index of
Unified Health System (PIUHS) by basic care coverage (I=-0.08; p=0.01).
Regarding chikungunya fever, there were positive spatial correlations with the
population density (I=0.06; p=0.03) and the Municipal Human Development Index
(MHDI) (I=0.10; p=0.002), and a negative correlation with the Gini index
(I=-0.01; p<0.001) and the PIUHS by basic care coverage (I=-0.18;
p<0.001). Lastly, we found positive spatial correlations between Zika virus
infections and the population density (I=0.13; p=0.005) and the MHDI (I=0.12;
p<0.001), as well as a negative correlation with the Gini index (I=-0.11;
p<0.001) and the PIUHS by basic care coverage (I=-0.05; p=0.03). Our results
suggest that several socio-demographic factors influenced the occurrence of
dengue fever, chikungunya fever, and zika virus infections in Maranhao
State.

Abstract
The study aimed to: (1) describe the work process in Brazil's oral health teams, based on the essential attributes of primary health care, according to geographic region, type of team, and the municipality's socioeconomic characteristics and (2) verify whether the data in the work process of the oral health teams in the Brazilian National Program to Improve Access and Quality in primary health (PMAQ-AB) were capable of measuring such attributes. This was a nationwide ecological study with data from cycle I of PMAQ-AB. The study included descriptive, exploratory factor, and confirmatory factor analyses (α = 5%). Constructs were analyzed in light of the essential attributes of primary health care (first contact, coordination of care, comprehensiveness, and continuity). The first three constructs and a fourth factor were formed, called dental prosthesis actions. However, the continuity attribute was not formed. The models' goodness-of-fit measures were satisfactory. Factor loads were greater than 0.5, except for the two variables in factor 3. The actions most frequently performed by the oral health teams (> 60%) were in first contact, and the least frequent were those in comprehensiveness, highlighting referrals to specialties (7.6%). There were differences in the work process in oral health teams between regions of the country, type of team, and certification strata (p < 0.05). In conclusion, data on the work process in oral health teams from cycle primary health care in the services' work routine. Further research is recommended on continuity of care. In addition, the oral health teams participating in cycle I of PMAQ-AB should make further progress in actions related to comprehensiveness and coordination of care.

Abstract
Background Although the Zika virus (ZIKV) epidemic ceased to be a public health emergency by the end of 2016, studies to improve knowledge about this emerging disease are still needed, especially those investigating a causal relationship between ZIKV in pregnant women and microcephaly in neonates. However, there are still many challenges in describing the relationship between ZIKV and microcephaly. The few studies focusing on the epidemiological profile of ZIKV and its changes over time are largely limited to systematic reviews of case reports and dispersal mapping of ZIKV spread over time without quantitative methods to analyze patterns and their covariates. Since Brazil has been at the epicenter of the ZIKV epidemic, this study examines the geospatial association between ZIKV and microcephaly in Brazil. Methods Our study is categorized as a retrospective, ecological study based on secondary databases. Data were obtained from January to December 2016, from the following data sources: Brazilian System for Epidemiological Surveillance, Disease Notification System, System for Specialized Management Support, and Brazilian Institute of Geography and Statistics. Data were aggregated by municipality. Incidence rates were estimated per 100,000 inhabitants. Analyses consisted of mapping the aggregated incidence rates of ZIKV and microcephaly, followed by a Getis-Ord-Gi spatial cluster analysis and a Bivariate Local Moran’s I analysis. Results The incidence of ZIKV cases is changing the virus’s spatial pattern, shifting from Brazil’s Northeast region to the Midwest and North regions. The number of municipalities in clusters of microcephaly incidence is also shifting from the Northeast region to the Midwest and North, after a time lag is considered. Our findings suggest an increase in microcephaly incidence in the Midwest and North regions, associated with high levels of ZIKV infection months before. Conclusion The greatest burden of microcephaly shifted from the Northeast to other Brazilian regions at the beginning of 2016. Brazil’s Midwest region experienced an increase in microcephaly incidence associated with ZIKV incidence. This finding highlights an association between an increase in ZIKV infection with a rise in microcephaly cases after approximately three months. The increasing evidence of a relationship between ZIKV in pregnant women and fetal congenital ZIKV syndrome with microcephaly has been reported in the literature over the last two years. Our findings suggest a spatial dependency between the diseases. Therefore, using the spatial pattern of ZIKV incidence to better understand risk areas for microcephaly may help the design of surveillance policies. Brazil had a large epidemic of ZIKV, leading to several important studies of the ZIKV outbreak and its association with microcephaly. This study used a geospatial analysis approach to examine the association between ZIKV and microcephaly in Brazilian regions. It was possible to highlight a spatial association between ZIKV and microcephaly considering a time lag between diseases. Brazilian regions with the highest incidences of microcephaly were the regions where the highest incidence of ZIKV occurred months before. This finding can help the organization and planning of health services to offer better screening actions dedicated to pregnant women in high-risk areas.

Abstract
This study estimated the percentages of incomplete immunization with new vaccines and old vaccines and associated factors in children 13 to 35 months of age belonging to a birth cohort in São Luís, the capital of Maranhão State, Brazil. The sample was probabilistic, with 3,076 children born in 2010. Information on vaccination was obtained from the Child's Health Card. The new vaccines, namely those introduced in 2010, were meningococcal C and 10-valent pneumococcal, and the old vaccines, or those already on the childhood immunization schedule, were BCG, hepatitis B, human rotavirus, polio, tetravalent (diphtheria, tetanus, pertussis, Haemophilus influenzae b), yellow fever, and triple viral (measles, mumps, rubella). The study used hierarchical modeling and Poisson regression with robust variance. Prevalence ratios (PR) and 95% confidence intervals (95%CI) were calculated. Incomplete immunization was higher with new vaccines (51.1%) than with old vaccines (33.2%). Children 25 to 35 months of age (PR = 1.27; 95%CI: 1.14-1.41) and those in economic classes D/E (PR = 1.20; 95%CI: 1.06-1.35) were only significantly associated with new vaccines; low maternal schooling (PR = 1.58; 95%CI: 1.21-2.06), unavailability of outpatient and/or hospital care for the child (PR = 1.20; 95%CI: 1.04-1.38), and unavailability of the vaccine in health services (PR: 1.28; 95%CI: 1.12-1.46) were only associated with old vaccines. Immunization strategies should consider the vulnerability of older preschool-age children and those belonging to classes D and E, especially when new vaccines are introduced, as well as children of mothers with low schooling. Strategies should also address problems with the availability of health services and vaccines.

Analysis of dengue cases according to clinical severity, São Luís, Maranhão, Brazil. Rev Inst Med Trop Sao Paulo 2017; 59:e71. [PMID: 29116291 PMCID: PMC5679683 DOI: 10.1590/s1678-9946201759071] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Accepted: 08/29/2017] [Indexed: 11/22/2022] Open
Abstract
Severe dengue cases have increased in Brazil since 2001, with the first records in Maranhão dating back to 2002. The aim of this study was to determine the prevalence of severe dengue cases by age group and the possible risk factors. This was a study of secondary data on dengue in residents of São Luís, Maranhão, Brazil, using probable cases notified to the National Mandatory Reporting System (SINAN) from 2002 to 2011. The diagnosis and classification of dengue were based on the Brazilian Ministry of Health criteria: dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue fever with complications (DWC). DHF and DWC were considered severe dengue, and DF was classified as non-severe dengue. A logistic regression analysis was performed with severe dengue as the outcome. During the study period, 1,229 cases of severe dengue were reported; of these, 812 in patients under the age of 15 (66%). Among the risk factors evaluated, age under 15 years old (OR = 3.10, 95% CI = 2.69-3.57, p-value = 0.001) was associated with severe dengue. The prevalence of severe dengue in children under the age of 15 was higher, and only this age group was associated with the occurrence of severe dengue.

Oral primary care: an analysis of its impact on the incidence and mortality rates of oral cancer. BMC Cancer 2017; 17:706. [PMID: 29084516 PMCID: PMC5661925 DOI: 10.1186/s12885-017-3700-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Accepted: 10/22/2017] [Indexed: 02/07/2023] Open
Abstract
Background Oral cancer is a potentially fatal disease, especially when diagnosed in advanced stages. In Brazil, the primary health care (PHC) system is responsible for promoting oral health in order to prevent oral diseases. However, there is insufficient evidence to assess whether actions of the PHC system have some effect on the morbidity and mortality from oral cancer. The purpose of this study was to analyze the effect of PHC structure and work processes on the incidence and mortality rates of oral cancer after adjusting for contextual variables. Methods An ecological, longitudinal and analytical study was carried out. Data were obtained from different secondary data sources, including three surveys that were nationally representative of Brazilian PHC and carried out over the course of 10 years (2002–2012). Data were aggregated at the state level at different times. Oral cancer incidence and mortality rates, standardized by age and gender, served as the dependent variables. Covariables (sociodemographic, structure of basic health units, and work process in oral health) were entered in the regression models using a hierarchical approach based on a theoretical model. Analysis of mixed effects with random intercept model was also conducted (alpha = 5%). Results The oral cancer incidence rate was positively association with the proportion of of adults over 60 years (β = 0.59; p = 0.010) and adult smokers (β = 0.29; p = 0.010). The oral cancer related mortality rate was positively associated with the proportion of of adults over 60 years (β = 0.24; p < 0.001) and the performance of preventative and diagnostic actions for oral cancer (β = 0.02; p = 0.002). Mortality was inversely associated with the coverage of primary care teams (β = −0.01; p < 0.006) and PHC financing (β = −0.52−9; p = 0.014). Conclusions In Brazil, the PHC structure and work processes have been shown to help reduce the mortality rate of oral cancer, but not the incidence rate of the disease. We recommend expanding investments in PHC in order to prevent oral cancer related deaths.

Addressing geographic access barriers to emergency care services: a national ecologic study of hospitals in Brazil. Int J Equity Health 2017; 16:149. [PMID: 28830521 PMCID: PMC5568346 DOI: 10.1186/s12939-017-0645-4] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2017] [Accepted: 08/10/2017] [Indexed: 11/18/2022] Open
Abstract
Background Unequal distribution of emergency care services is a critical barrier to be overcome to assure access to emergency and surgical care. Considering this context it was objective of the present work analyze geographic access barriers to emergency care services in Brazil. A secondary aim of the study is to define possible roles to be assumed by small hospitals in the Brazilian healthcare network to overcome geographic access challenges. Methods The present work can be classified as a cross-sectional ecological study. To carry out the present study, data of all 5843 Brazilian hospitals were categorized among high complexity centers and small hospitals. The geographical access barriers were identified through the use of two-step floating catchment area method. Once concluded the previous step an evaluation using the Getis-Ord-Gi method was performed to identify spatial clusters of municipalities with limited access to high complexity centers but well covered by well-equipped small hospitals. Results The analysis of accessibility index of high complexity centers highlighted large portions of the country with nearly zero hospital beds by inhabitant. In contrast, it was possible observe a group of 1595 municipalities with high accessibility to small hospitals, simultaneously with a low coverage of high complexity centers. Among the 1595 municipalities with good accessibility to small hospitals, 74% (1183) were covered by small hospitals with at least 60% of minimum emergency service requirements. The spatial clusters analysis aggregated 589 municipalities with high values related to minimum emergency service requirements. Small hospitals in these 589 cities could promote the equity in access to emergency services benefiting more than eight million people. Conclusions There is a spatial disequilibrium within the country with prominent gaps in the health care network for emergency services. Taking this challenge into consideration, small hospitals could be a possible solution and foster equity in access to emergency and surgical care. However more investments in are necessary to improve small hospitals capabilities to fill this gap.

Structure and work process in primary care and hospitalizations for sensitive conditions. Rev Saude Publica 2017; 51:75. [PMID: 28832757 PMCID: PMC5559214 DOI: 10.11606/s1518-8787.2017051007033] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2016] [Accepted: 08/30/2016] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. METHODS In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). RESULTS In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013. CONCLUSIONS The characteristics of the structure of primary health units and the work process of the primary care teams impact the number of hospitalizations for primary care sensitive conditions in Brazilian municipalities.

Abstract
INTRODUCTION Currently, dengue fever, chikungunya fever, and zika virus represent serious public health issues in Brazil, despite efforts to control the vector, the Aedes aegypti mosquito. METHODS: This was a descriptive and ecological study of dengue deaths occurring from 2002 to 2013 in São Luis, Maranhão, Brazil. Geoprocessing software was used to draw maps, linking the geo-referenced deaths with urban/social data at census tract level. RESULTS: There were 74 deaths, concentrated in areas of social vulnerability. CONCLUSIONS: The use of geo-technology tools pointed to a concentration of dengue deaths in specific intra-urban areas.

Abstract
OBJECTIVE to evaluate productivity targets achievement (PTA) in Dental Specialty Centers (DSCs) from Maranhão State, Brazil. METHODS this was an ecologic study using secondary data; an indicator for PTA was created for each subgroup of procedures. RESULTS 25 DSCs were evaluated; the PTA was higher for basic procedures (n=19), followed by endodontics (n=11), oral surgery (n=9) and periodontics (n=8); the best results were obtained at DSCs type II; higher PTA was associated with financial anticipation (basic procedures) and higher Human Development Index, life expectancy and social exclusion rate (endodontics); lower PTA was associated with larger population (endodontics/oral surgery), adherence to the Pact for Health (periodontics/endodontics), larger number of specialties (periodontics) and bigger DSC (oral surgery). CONCLUSION most DSCs did not achieve productivity targets, except for basic procedures; socioeconomic and health management characteristics of the municipalities were associated with the PTA; the DSCs characteristics explained little about the PTA.
