RESUMO
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.

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 (1â1, 3â4, 2â2); 228 (24.9%) switched to a worse status (2â1, 2â4, 3â1) and 269 (29.4%) switched to a better LS (1â2, 1â4, 3â2). 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.

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.

This article explores the use of spatial artificial intelligence to estimate the resources needed to implement Brazil's COVID-19 immu nization campaign. Using secondary data, we conducted a cross-sectional ecological study adop ting a time-series design. The unit of analysis was Brazil's primary care centers (PCCs). A four-step analysis was performed to estimate the popula tion in PCC catchment areas using artificial in telligence algorithms and satellite imagery. We also assessed internet access in each PCC and con ducted a space-time cluster analysis of trends in cases of SARS linked to COVID-19 at municipal level. Around 18% of Brazil's elderly population live more than 4 kilometer from a vaccination point. A total of 4,790 municipalities showed an upward trend in SARS cases. The number of PCCs located more than 5 kilometer from cell towers was largest in the North and Northeast regions. Innovative stra tegies are needed to address the challenges posed by the implementation of the country's National COVID-19 Vaccination Plan. The use of spatial artificial intelligence-based methodologies can help improve the country's COVID-19 response.
O objetivo deste artigo é analisar o uso da inteligência artificial espacial no contexto da imunização contra COVID-19 para a seleção adequada dos recursos necessários. Trata-se de estudo ecológico de caráter transversal baseado em uma abordagem espaço-temporal utilizando dados secundários, em Unidades Básicas de Saúde do Brasil. Foram adotados quatro passos analíticos para atribuir um volume de população por unidade básica, aplicando algoritmos de inteligência artificial a imagens de satélite. Em paralelo, as condições de acesso à internet móvel e o mapeamento de tendências espaço-temporais de casos graves de COVID-19 foram utilizados para caracterizar cada município do país. Cerca de 18% da população idosa brasileira está a mais de 4 quilômetros de distância de uma sala de vacina. No total, 4.790 municípios apresentaram tendência de agudização de casos de Síndrome Respiratória Aguda Grave. As regiões Norte e Nordeste apresentaram o maior número de Unidades Básicas de Saúde com mais de 5 quilômetros de distância de antenas de celular. O Plano nacional de vacinação requer o uso de estratégias inovadoras para contornar os desafios do país. O uso de metodologias baseadas em inteligência artificial espacial pode contribuir para melhoria do planejamento das ações de resposta à COVID-19.

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.
Objetivou-se analisar a correlação da qualidade dos serviços da Atenção Primária na redução da mortalidade infantil, através do geoprocessamento. Um estudo ecológico, de abordagem transversal, em que foram utilizados dados secundários de todos os 5.565 municípios brasileiros para análise da taxa de mortalidade infantil (TMI) e causa de óbito infantil. Os dados da TMI foram obtidos no Sistema de Informação de Mortalidade. Para a análise espacial, incluímos 5.011 municípios. As análises de clusterização ocorreram no software GEODA e as análises de regressão espacial no ARCGIS 10.5. No Brasil houve uma redução de 45,07% da TMI entre os anos 2000 e 2015. A maior redução ocorreu na região nordeste do país, apesar de ainda ser a região com maior número na TMI. Dos 749 municípios analisados no cluster diferencial para óbito infantil, 153 apresentaram alta TMI. As áreas com maior expansão de alta TMI foram encontradas nas regiões Norte e Nordeste. No Brasil, a TMI mostrou-se inversamente associada à acessibilidade aos serviços de alta complexidade, ao estrato da gestão em saúde e porte populacional, à referência para o parto, à taxa de nascidos vivos, à renda per capita e à taxa de desemprego. Verificou-se uma crescente redução da TMI entre o período de 2000 a 2015.

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.

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.

BACKGROUND: Health systems for surgical care for children in low- and middle-income countries remain poorly understood. Our goal was to characterize the delivery of surgical care for children across Brazil and to identify associations between surgical resources and childhood mortality. METHODS: We performed a cross-sectional, ecological study to analyze surgical care for children in the public health system (Sistema Único de Saúde) across Brazil from 2010 to 2015. We collected data from several national databases, and used geospatial analysis (two-step floating catchment, Getis-Ord-Gi analysis, and geographically weighted regression) to explore relationships between infrastructure, workforce, access, procedure rate, under-5 mortality rate (U5MR), and perioperative mortality rate (POMR). RESULTS: A total of 246,769 surgical procedures were performed in 6,007 first level/ district hospitals and 491 referral hospitals across Brazil over the study period. The surgical workforce is distributed unevenly across the country, with 0.13-0.26 pediatric surgeons per 100,000 children in the poorer North, Northeast and Midwest regions, and 0.6-0.68 pediatric surgeons per 100,000 children in the wealthier South and Southeast regions. Hospital infrastructure, procedure rate, and access to care is also unequally distributed across the country, with increased resources in the South and Southeast compared to the Northeast, North, and Midwest. The U5MR varies widely across the country, although procedure-specific POMR is consistent across regions. Increased access to care is associated with lower U5MR across Brazil, and access to surgical care differs by geographic region independent of socioeconomic status. CONCLUSIONS: There are wide disparities in surgical care for children across Brazil, with infrastructure, manpower, and resources distributed unevenly across the country. Access to surgical care is associated with improved U5MR independent of socioeconomic status. To address these disparities, policy should direct the allocation of surgical resources commensurate with local population needs.

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.

This study compared the reliability of a data group registered in the secondary databases of the National Registry of Health Facilities. A survey was conducted in 2,777 with hospitals to achieve this objective. Visited hospitals provided information on equipment, geographic location, operating status and number of beds. Regarding matching data between visited hospitals and the National Registry, it can be noted that the operating status was updated in 89% of cases, the number of beds in 44%, 82% had the correct amount of equipment and 63% had accurate geographic coordinates. These findings point to a good reliability of information from the National Registry of Health Facilities, regarding the compared categories, excepting for data on the number of registered beds and for some equipment. As a further development of this work, we stress the need to discuss strategies and incentives to improve the reliability of data that still have inconsistencies, in order to improve the instruments used to formulate public policies.
O presente trabalho comparou a confiabilidade de um grupo de dados registrados junto às bases secundárias do Cadastro Nacional dos Estabelecimentos de Saúde. Para cumprir este objetivo, o trabalho foi realizado em 'survey' com 2.777 hospitais. Os hospitais visitados forneceram dados sobre equipamentos, localização geográfica, status de funcionamento e número de leitos. Quanto à concordância entre os hospitais visitados e o cadastro nacional, pode-se destacar que o status de funcionamento estava atualizado em 89% dos casos, o número de leitos em 44%, 82% mantinham o quantitativo de equipamentos correto e 63% apresentaram coordenadas geográficas precisas. Esses achados apontam para uma boa confiabilidade dos dados do Cadastro Nacional dos Estabelecimentos de Saúde, quanto às categorias comparadas, excetuando-se os dados referentes ao número de leitos cadastrados e quanto a existência de alguns equipamentos. Como desdobramento deste trabalho pesa a necessidade de discutir estratégias e incentivos para melhorar a confiabilidade dos dados que ainda apresentam inconsistências, de forma a ampliar a qualidade dos instrumentos utilizados para a formulação de políticas públicas.

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.

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.
Os objetivos do estudo foram: (1) descrever o processo de trabalho das equipes de saúde bucal (ESB) do Brasil, com base nos atributos essenciais da atenção primária à saúde, segundo regiões, tipo de equipe e características socioeconômicas dos municípios; e (2) verificar se os dados do processo de trabalho das ESB do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) foram capazes de aferir tais atributos. Estudo ecológico, de abrangência nacional, com dados do ciclo I do PMAQ-AB. Foram feitas análises descritivas, fatoriais exploratória e confirmatória (α = 5%). Os construtos formados foram analisados à luz dos atributos essenciais da atenção primária à saúde (primeiro contato, coordenação do cuidado, integralidade e longitudinalidade). Formaram-se os três primeiros construtos e um quarto fator, denominado ações em prótese dentária. Porém, o atributo longitudinalidade não foi conformado. As medidas de ajuste dos modelos foram satisfatórias. As cargas fatoriais foram maiores que 0,5, exceto para duas variáveis do fator 3. As ações mais realizadas pelas ESB (> 60%) foram as do primeiro contato e as menos comuns foram as da integralidade, destacando-se ter referência para especialidades (7,6%). Houve diferenças no processo de trabalho das ESB entre as regiões, tipo de equipe e estrato de certificação (p < 0,05). Conclui-se que os dados de processo de trabalho das ESB do ciclo I do PMAQ-AB foram capazes de discriminar três dos quatro atributos essenciais da atenção primária à saúde na rotina dos serviços. Sugere-se aprofundar a avaliação da longitudinalidade. Ademais, as ESB participantes do ciclo I do PMAQ-AB precisam avançar nas ações relacionadas à integralidade e coordenação do cuidado.

Es un estudio ecológico, de cobertura nacional, con datos del ciclo I del PMAQ-AB. Se realizaron análisis descriptivos, factoriales exploratorios y confirmatorios (α = 5%). Los constructos creados se analizaron a la luz de los atributos esenciales de la atención primaria a la salud (primer contacto, coordinación del cuidado, integralidad y longitudinalidad). Se generaron los tres primeros constructos, y un cuarto factor, denominado acciones en prótesis dental. No obstante, el atributo longitudinalidad no se configuró. Las medidas de ajuste de los modelos fueron satisfactorias. Las cargas factoriales fueron mayores que 0,5, excepto en dos variables del factor 3. Las acciones más realizadas por las ESB (> 60%) fueron las de primer contacto, y las menos comunes fueron las de integralidad, destacándose contar con referencias para especialidades (7,6%). Hubo diferencias en el proceso de trabajo de las ESB entre las regiones, tipo de equipo y extracto de certificación (p < 0,05). Se concluye que los datos del proceso de trabajo de las ESB del ciclo I del PMAQ-AB fueron capaces de discriminar tres de los cuatro atributos esenciales de la atención primaria a la salud en la rutina de los servicios. Se sugiere profundizar en la evaluación de la longitudinalidad. Además, las ESB participantes del ciclo I del PMAQ-AB necesitan avanzar en acciones relacionadas con la integralidad y coordinación del cuidado.

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.

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 (ß) 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 (ß = -0.001) and private insurance (ß = -0.01) had a negative association, and the human development index (ß = 1.13), the proportion of older adults (ß = 0.05) and children under the age of five (ß = 0.05), and the coverage of the Community Health Agent Strategy (ß = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (ß = -0.14) and availability of vaccines (ß = -0.16) showed a negative association, and availability of medications showed a positive association (ß = 0.16). In the proximal level, only the variable of matrix support (ß = 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. OBJETIVO: Investigar se características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica estão associadas ao número de internações por condições sensíveis à atenção primária. MÉTODOS: Neste estudo ecológico, foram analisados dados de municípios brasileiros relativos a características sociodemográficas, de cobertura de programas assistenciais, de estrutura das unidades básicas de saúde e processo de trabalho das equipes de atenção básica. Os dados foram obtidos do primeiro ciclo do Programa de Melhoria do Acesso e Qualidade da Atenção Básica, do Departamento de Informática do Sistema Único de Saúde, do Instituto Brasileiro de Geografia e Estatística e do Programa das Nações Unidas. Estimaram-se as associações por meio de coeficientes de regressão binomial negativa (ß) e respectivos intervalos de confiança a 95%, com abordagem hierarquizada em três blocos (alpha = 5%). RESULTADOS: Na análise ajustada, para o desfecho em 2013, no bloco distal, a cobertura do Programa Bolsa Família (ß = -0,001) e de plano privado (ß = -0,01) apresentaram associação negativa; e o índice de desenvolvimento humano (ß = 1,13), a proporção de pessoa idosa (ß = 0,05) e de menor de cinco anos (ß = 0,05) e a cobertura da Estratégia de Agentes Comunitários de Saúde (ß = 0,002) mostraram associação positiva com internações por condições sensíveis à atenção primária. No bloco intermediário, apresentaram associação negativa o horário mínimo (ß = -0,14) e a disponibilidade de vacina (ß = -0,16); e associação positiva, a disponibilidade de medicamentos (ß = 0,16). No bloco proximal, apenas a variável apoio matricial (ß = 0,10) mostrou associação positiva. Na análise ajustada do número de internações por condições sensíveis à atenção primária em 2014, as variáveis apresentaram o mesmo sentido de associação de 2013. CONCLUSÕES: Características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica impactam no número de internações por condições sensíveis à atenção primária nos municípios brasileiros.

RESUMO Objetivo. Identificar a associação da estrutura das unidades básicas de saúde (UBS) e do processo de trabalho das equipes de atenção primária com determinantes sociais e taxas de internações por condições sensíveis à atenção primária (ICSAP) em menores de 5 anos no Brasil. Métodos. Estudo longitudinal ecológico, com dados secundários do Sistema de Informações Hospitalares e dos três ciclos do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) (2012, 2014, 2017/2018). Foram analisadas 42 916 UBS. Foi realizada modelagem multinível com angulação fixa e intercepto aleatório. No primeiro nível, foram analisados o desfecho (taxas de ICSAP) e as variáveis explicativas (indicadores estruturais e processuais), agregados por UBS. No segundo nível, foram incluídos determinantes sociais municipais (representados por critério de estratificação que combina o porte do município com indicadores que influenciam a gestão de saúde). Utilizou-se o teste t com correção de Bonferroni para comparar as médias dos indicadores entre as regiões, e a regressão linear multinível para estimar os coeficientes de correlação. Resultados. A taxa de ICSAP em menores de 5 anos foi de 62,78/100 mil habitantes por área estimada de cobertura de UBS. Apresentaram associação direta com o desfecho: participação em um ou mais ciclos do PMAQ-AB; planejamento da equipe; horário especial; dependências para atenção infantil na unidade; e disponibilidade de vacinas. A variável equipamentos, materiais e insumos e a classificação como município de porte pequeno ou médio associaram-se inversamente às ICSAP. Conclusões. As ICSAP em menores de 5 anos podem ser potencialmente reduzidas pela melhoria dos indicadores estruturais e processuais das UBS e dos determinantes sociais municipais.
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.
RESUMEN Objetivo. Determinar la asociación de la estructura de las unidades básicas de salud (UBS) y del proceso de trabajo de los equipos de atención primaria con los determinantes sociales y las tasas de hospitalización por afecciones que podrían tratarse en la atención primaria en menores de 5 años en Brasil. Métodos. Estudio longitudinal ecológico, con datos secundarios del Sistema de Informaciones Hospitalarias y los tres ciclos del Programa Nacional de Mejora del Acceso y de la Calidad de la Atención Básica (PMAQ-AB) (2012, 2014, 2017-2018). Se analizaron 42.916 UBS. Se aplicó un modelo multinivel con pendiente fija e intercepción aleatoria. En el primer nivel, se analizaron el desenlace (tasas de hospitalización por afecciones que podrían tratarse en los servicios de atención primaria) y las variables explicativas (indicadores estructurales y procedimentales) consolidados por UBS. En el segundo nivel, se incluyeron determinantes sociales municipales (representados por un criterio de estratificación que combina el tamaño del municipio con indicadores que influyen en la gestión de salud). Se utilizó la prueba de la t con la corrección de Bonferroni para comparar las medias de los indicadores entre las regiones y la regresión lineal multinivel para estimar los coeficientes de correlación. Resultados. La tasa de hospitalización por afecciones que podrían tratarse en los servicios de atención primaria en menores de 5 años fue de 62,78/100 mil habitantes por área estimada de cobertura de UBS. Los siguientes factores presentaron una asociación directa con el desenlace: participación en uno o más ciclos del PMAQ-AB; planificación del equipo; horario especial; dependencias de atención infantil en la unidad; y disponibilidad de vacunas. La variable relativa a equipos, materiales e insumos y la clasificación como municipio pequeño o mediano se asociaron inversamente con las hospitalizaciones por afecciones que podrían tratarse en los servicios de atención primaria. Conclusiones. Las hospitalizaciones de menores de 5 años por afecciones que podrían tratarse en los servicios de atención primaria pueden reducirse mejorando los indicadores estructurales y procedimentales de las UBS y los determinantes sociales municipales.
RESUMO
Cervical cancer is a common neoplasm that is responsible for nearly 230 000 deaths annually in Brazil. Despite this burden, cervical cancer is considered preventable with appropriate care. We conducted a longitudinal ecological study from 2002 to 2012 to examine the relationship between the delivery of preventive primary care and cervical cancer mortality rates in Brazil. Brazilian states and the federal district were the unit of analysis (N = 27). Results suggest that primary health care has contributed to reducing cervical cancer mortality rates in Brazil; however, the full potential of preventive care has yet to be realized.

OBJECTIVE: to review and discuss new perspectives for healthcare provision resulting from the development of mobile health and intelligent wearable devices. METHODS: an unsystematic literature review was conducted to identify complete articles published in the last 15 years with titles highlighting the term 'mHealth' and/or 'Smart wearable'. RESULTS: 467 publications were identified in journals indexed on the CAPES portal, of which 75 were considered for analysis; evidence was then consolidated as to new possibilities arising from the spread of mobile health, grouped into the following categories: 'health status monitoring', 'information transmission and data analysis', and 'diagnosis and therapy'. CONCLUSION: the studies reviewed suggest that healthcare provision will change over the coming years with regard to the categories analyzed. This will require adaptation on the part of health professionals, academics and service users.

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.

Resumo Objetivou-se analisar a correlação da qualidade dos serviços da Atenção Primária na redução da mortalidade infantil, através do geoprocessamento. Um estudo ecológico, de abordagem transversal, em que foram utilizados dados secundários de todos os 5.565 municípios brasileiros para análise da taxa de mortalidade infantil (TMI) e causa de óbito infantil. Os dados da TMI foram obtidos no Sistema de Informação de Mortalidade. Para a análise espacial, incluímos 5.011 municípios. As análises de clusterização ocorreram no software GEODA e as análises de regressão espacial no ARCGIS 10.5. No Brasil houve uma redução de 45,07% da TMI entre os anos 2000 e 2015. A maior redução ocorreu na região nordeste do país, apesar de ainda ser a região com maior número na TMI. Dos 749 municípios analisados no cluster diferencial para óbito infantil, 153 apresentaram alta TMI. As áreas com maior expansão de alta TMI foram encontradas nas regiões Norte e Nordeste. No Brasil, a TMI mostrou-se inversamente associada à acessibilidade aos serviços de alta complexidade, ao estrato da gestão em saúde e porte populacional, à referência para o parto, à taxa de nascidos vivos, à renda per capita e à taxa de desemprego. Verificou-se uma crescente redução da TMI entre o período de 2000 a 2015.
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.

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.
Analisamos a relação espacial entre cobertura vacinal incompleta em crianças e a distância da residência até os serviços de vacinação. Este foi um estudo transversal de crianças entre 13 e 35 meses de idade nas cidades de São Luís (Maranhão) e Ribeirão Preto (São Paulo), Brasil, e das unidades básicas de saúde (UBS). A amostra consistia em 2.744 crianças de São Luís e 3.325 de Ribeirão Preto. Os dados sobre a cobertura vacinal incompleta foram obtidos das coortes de nascimento BRISA. Os dados sobre a qualidade dos serviços de vacinação das UBS foram obtidos do primeiro ciclo do Programa de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). Para a análise espacial, determinamos a distância da residência das crianças (com e sem calendário vacinal completo) até os serviços de vacinação da UBS (classificados de acordo com o número de itens estruturais). A cobertura vacinal incompleta era mais marcante em São Luís, com percentuais mais altos para as vacinas do rotavírus humano e tríplice viral, sendo que esta era menos disponível. Em Ribeirão Preto, a cobertura vacinal incompleta para BCG era mais evidente, enquanto a vacina tetravalente era a menos disponível. As crianças das duas cidades mostraram semelhanças: a maioria tinha mães adultas com 9 a 11 anos de escolaridade e não residia com irmãos no domicílio. Também mostravam diferenças: em São Luís, a maioria das mães pertencia à classe econômica C, enquanto as mães em Ribeirão Preto pertenciam mais às classes A e B. Nas duas cidades, com condições socioeconômicas diferentes, a cobertura vacinal completa parecia não depender da localização ou da qualidade do serviço de vacinação. Embora São Luís tenha demonstrado melhor estrutura dos serviços, a cobertura vacinal incompleta foi mais alta em São Luís quando comparada à de Ribeirão Preto.
Analizamos la relación espacial entre los niños con una cobertura de vacunación incompleta y la distancia que los separa de los servicios de vacunación. Se trata de un estudio transversal con niños desde los 13 a los 35 meses de edad en las ciudades de São Luís (Maranhão) y Ribeirão Preto (São Paulo), Brasil, y en unidades básicas de salud (UBS por sus siglas en portugués). La muestra consistió en 2.744 niños de São Luís y 3.325 de Ribeirão Preto. Los datos sobre la cobertura de vacunación incompleta de los niños proceden de las cohortes de nacimiento BRISA. Los datos sobre la calidad de los servicios de vacunación en los servicios UBS se obtuvieron del 1er ciclo del Programa Nacional de Mejoría de Acceso y Calidad de la Atención Básica (PMAQ-AB). Para el análisis espacial, determinamos la distancia entre la residencia de los niños (con y sin un calendario de vacunas completo) y los servicios de vacunación de las UBS (clasificados según el número de ítems estructurales). Se destacó una cobertura incompleta de vacunación en São Luís, con porcentajes de vacunas contra rotavirus humano y triple vírica, siendo esta última la menos disponible. En Ribeirão Preto, la cobertura incompleta de la vacuna BCG fue la más destacable y la vacuna tetravalente fue la menos disponible. Los niños de las dos ciudades mostraron similitudes: la mayoría de ellos tenían madres adultas con una escolaridad que oscilaba entre los 9 y los 11 años de edad y no residían con hermanos en el hogar. Asimismo, mostraron también diferencias: en São Luís, la mayoría de las madres pertenecían a la clase económica C, mientras que en Ribeirão Preto pertenecían las clases A y B. En las dos ciudades con condiciones diferentes socioeconómicas, la cobertura completa de vacunación parecía no depender de la localización o la calidad del servicio de vacunación. Sin embargo, São Luís mostró una mejor estructura de los servicios, aunque la cobertura incompleta de vacunación fue más alta comparada con Ribeirão Preto.
