Bolsa Família Program and deaths from oral cancer in Brazil: an ecological study

[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.

[RESUMEN]. Objetivo. Evaluar el efecto de la cobertura del Programa Bolsa Família (BFP) en las tasas de mortalidad por cáncer de la cavidad bucal en Brasil entre el 2005 y el 2017, ajustadas por cobertura de atención de salud y características socioeconómicas de las unidades federativas brasileñas. Métodos. Este es un estudio ecológico con datos anuales (2005-2017) de todas las unidades federativas brasileñas. La variable dependiente de este estudio fue la tasa de mortalidad por cáncer de la cavidad bucal, estandarizada por sexo y edad mediante la técnica de estandarización directa. La cobertura del BFP fue la principal variable independiente, calculada como la relación entre el número de beneficiarios del BFP y las familias que podrían tener el derecho a recibir esta transferencia monetaria condicionada. Los antecedentes socioeconómicos y la cobertura de atención de salud fueron covariables. Se trazaron mapas coropléticos y se realizó un análisis con cubos espaciotemporales para evaluar los cambios en la distribución espaciotemporal del BFP y las tasas de mortalidad por cáncer de la cavidad bucal. El análisis de regresión lineal de efectos mixtos calculó los coeficientes (β) y los intervalos de confianza (IC) del 95% para la relación entre la cobertura del BFP y las tasas de mortalidad por cáncer de la cavidad bucal. Resultados. Las tendencias de cobertura del BFP aumentaron y las tendencias de la tasa de mortalidad por cáncer de la cavidad bucal se estabilizaron en las unidades federativas brasileñas, excepto en Maranhão, Goiás y Minas Gerais, donde estas tasas aumentaron. En el modelo ajustado, una mayor cobertura del BFP se asoció con tasas más bajas de mortalidad por cáncer de la cavidad bucal (β –2,10; IC del 95% [–3,291, –0,919]). Conclusiones. Las estrategias igualitarias como el BFP pueden reducir la tasa de mortalidad por cáncer de la cavidad bucal. Recomendamos el seguimiento por parte de los equipos de salud bucodental de las familias que se benefician del programa de transferencias monetarias condicionadas para reducir la tasa de mortali- dad por cáncer de la cavidad bucal.

Recomendamos o acompanhamento das famílias beneficiadas por programas de transferência condicionada de renda por equipes de saúde bucal para reduzir a taxa de mortalidade por esse câncer.

Access to care solutions in healthcare for obstetric care in Africa: A systematic review.

BACKGROUND: Emergency Medical Services (EMS) systems exist to reduce death and disability from life-threatening medical emergencies. Less than 9% of the African population is serviced by an emergency medical services transportation system, and nearly two-thirds of African countries do not have any known EMS system in place. One of the leading reasons for EMS utilization in Africa is for obstetric emergencies. The purpose of this systematic review is to provide a qualitative description and summation of previously described interventions to improve access to care for patients with maternal obstetric emergencies in Africa with the intent of identifying interventions that can innovatively be translated to a broader emergency context. METHODS: The protocol was registered in the PROSPERO database (International Prospective Register of Systematic Reviews) under the number CRD42018105371. We searched the following electronic databases for all abstracts up to 10/19/2020 in accordance to PRISMA guidelines: PubMed/MEDLINE, Embase, CINAHL, Scopus and African Index Medicus. Articles were included if they were focused on a specific mode of transportation or an access-to-care solution for hospital or outpatient clinic care in Africa for maternal or traumatic emergency conditions. Exclusion criteria included in-hospital solutions intended to address a lack of access. Reference and citation analyses were performed, and a data quality assessment was conducted. Data analysis was performed using a qualitative metasynthesis approach. FINDINGS: A total of 6,457 references were imported for screening and 1,757 duplicates were removed. Of the 4,700 studies that were screened against title and abstract, 4,485 studies were excluded. Finally, 215 studies were assessed for full-text eligibility and 152 studies were excluded. A final count of 63 studies were included in the systematic review. In the 63 studies that were included, there was representation from 20 countries in Africa. The three most common interventions included specific transportation solutions (n = 39), community engagement (n = 28) and education or training initiatives (n = 27). Over half of the studies included more than one category of intervention. INTERPRETATION: Emergency care systems across Africa are understudied and interventions to improve access to care for obstetric emergencies provides important insight into existing solutions for other types of emergency conditions. Physical access to means of transportation, efforts to increase layperson knowledge and recognition of emergent conditions, and community engagement hold the most promise for future efforts at improving emergency access to care.

A painful journey to antivenom: The therapeutic itinerary of snakebite patients in the Brazilian Amazon (The QUALISnake Study).

Access to antivenoms is not guarranteed for vulnerable populations that inhabit remote areas in the Amazon. The study of therapeutic itineraries (TI) for treatment of snakebites would support strategies to provide timely access to users. A TI is the set of processes by which individuals adhere to certain forms of treatment, and includes the path traveled in the search for healthcare, and practices to solve their health problems. This study aims to describe TIs of snakebite patients in the Brazilian Amazon. This study was carried out at the Fundação de Medicina Tropical Doutor Heitor Vieira Dourado, in Manaus, state of Amazonas, Brazil. The itinerary from the moment of the bite to the patient's admission to the reference unit was analyzed. Sample size was defined by saturation. After an exploratory survey to collect epidemiological variables, in-depth interviews were conducted following a semi-structured guide. Patients originated from rural areas of 11 different municipalities, including ones located >500 kilometers from Manaus. A great fragmentation was observed in the itineraries, marked by several changes of means of transport along the route. Four themes emerged from the analysis: exposure to snakebite during day-to-day activities, use of traditional therapeutic practices, and personal perception of the severity, as well as the route taken and its contingencies. Access to healthcare requires considerable effort on the part of snakebite patients. Major barriers were identified, such as the low number of hospitals that offer antivenom treatment, poor access to healthcare due to long distances and geographic barriers, low acceptability of healthcare offered in countryside, lack of use of personal protective equipment, common use of ineffective or deleterious self-care practices, late recognition of serious clinical signs and resistance to seeking medical assistance. Health education, promotion of immediate transport to health centers and decentralization of antivenom from reference hospitals to community healthcare centers in the Brazilian Amazon are more effective strategies that would to maximize access to antivenom treatment.

Progress and challenges in potential access to oral health primary care services in Brazil: A population-based panel study with latent transition analysis.

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.

Emergency Care Sensitive Conditions in Brazil: A Geographic Information System Approach to Timely Hospital Access.

Background: The benefits of treatment for many conditions are time dependent. The burden of these emergency care sensitive conditions (ECSCs) is especially high in low- and middle-income countries. Our objective was to analyze geospatial trends in ECSCs and characterize regional disparities in access to emergency care in Brazil. Methods: From publicly available datasets, we extracted data on patients assigned an ECSC-related ICD-10 code and on the country's emergency facilities from 2015-2019. Using ArcGIS, OpenStreetMap, and WorldPop, we created catchment areas corresponding to 180 minutes of driving distance from each hospital. We then used ArcGIS to characterize space-time trends in ECSC admissions and to complete an Origin-Destination analysis to determine the path from household to closest hospital. Findings: There were 1362 municipalities flagged as "hot spots," areas with a high volume of ECSCs. Of those, 69.7% were more than 180 minutes (171 km) from the closest emergency facility. These municipalities were primarily located in the states of Minas Gerais, Bahia, Espiríto Santo, Tocantins, and Amapá. In the North region, only 69.1% of the population resided within 180 minutes of an emergency hospital. Interpretations: Significant geographical barriers to accessing emergency care exist in certain areas of Brazil, especially in peri-urban areas and the North region. One limitation of this approach is that geolocation was not possible in some areas and thus we are likely underestimating the burden of inadequate access. Subsequent work should evaluate ECSC mortality data. Funding: This study was funded by the Duke Global Health Institute Artificial Intelligence Pilot Project.

Data-driven risk stratification for preterm birth in Brazil: a population-based study to develop of a machine learning risk assessment approach.

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.

Providing Antivenom Treatment Access to All Brazilian Amazon Indigenous Areas: 'Every Life Has Equal Value'.

Snakebites are more frequent in the Brazilian Amazon than in other parts of Brazil, representing a high cost for the health system since antivenoms are only available through medical prescription from central municipal hospitals in most cases. The need for a cold chain and physicians usually restricts access to the only effective treatment of a snakebite, the antivenom. The complex topography of the rivers contributes to delays in treatment, and consequently increases the risk of severe complications, chronic sequelae and death. Thus, decentralization of antivenom treatment to primary healthcare facilities in the interior would increase access by indigenous population groups to proper healthcare. To standardize and evaluate the decentralization to low complexity indigenous healthcare units, we suggest the (i) development and validation of standardized operational procedures, (ii) training of professionals in the validated protocol in a referral health unit, (iii) implementation of the protocol in an indigenous healthcare unit, (iv) assessment of perceptions towards and acceptability of the protocol, and (v) estimation of the impact of the protocol's implementation. We expect that antivenom decentralization would shorten the time between diagnosis and treatment and, as such, improve the prognosis of snakebites. As health cosmology among indigenous populations has an important role in maintaining their way of life, the introduction of a new therapeutic strategy to their customs must take into account the beliefs of these peoples. Thus, antivenom administration would be inserted as a crucial therapeutic tool in a world of diverse social, natural and supernatural representations. The information presented here also serves as a basis to advocate for support and promotion of health policy initiatives focused on evidence-based care in snakebite management.

Comprehending the lack of access to maternal and neonatal emergency care: Designing solutions based on a space-time approach.

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.

Characteristics of primary care and rates of pediatric hospitalizations in Brazil.

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.

Validity and reliability of telephone administration of the patient-specific functional scale for the assessment of recovery from snakebite envenomation.

OBJECTIVES: Although more than 1.8 million people survive snakebite envenomation each year, their recovery is understudied. Obtaining long-term follow-up is challenging in both high- and low-resource settings. The Patient-Specific Functional Scale (PSFS) is an easily administered, well-accepted patient-reported outcome that is validated for assessing limb recovery from snakebite envenomation. We studied whether the PSFS is valid and reliable when administered by telephone. METHODS: This is a secondary analysis of data from a randomized clinical trial. We analyzed the results of PSFS collected in-person on days 3, 7, 14, 21, and 28 and by telephone on days 10, 17, and 24. We assessed the following scale psychometric properties: (a) content validity (ceiling and floor effects), (b) internal structure and consistency (Cronbach's alpha), and (c) temporal and external validity using Intraclass Correlation Coefficient (ICC). Temporal stability was assessed using Spearman's correlation coefficient and agreement between adjacent in-person and telephonic assessments with Cohen's kappa. Bland Altman analysis was used to assess differential bias in low and high score results. RESULTS: Data from 74 patients were available for analysis. Floor effects were seen in the early post-injury time points (median: 3 (IQR: 0, 5) at 3 days post-enrollment) and ceiling effects in the late time points (median: 9 (IQR: 8, 10). Internal consistency was good to excellent with both in-person (Cronbach α: 0.91 (95%CI 0.88, 0.95)) and telephone administration (0.81 (0.73, 0.89). Temporal stability was also good (ICC: 0.83 (0.72, 0.89) in-person, 0.80 (0.68, 0.88) telephone). A strong linear correlation was found between in-person and telephone administration (Spearman's ρ: 0.83 (CI: 0.78, 0.84), consistency was assessed as excellent (Cohen's κ 0.81 (CI: 0.78, 0.84), and Bland Altman analysis showed no systematic bias. CONCLUSIONS: Telephone administration of the PSFS provides valid, reliable, and consistent data for the assessment of recovery from snakebite envenomation.

Characteristics of basic health units and detection of tuberculosis cases.

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?

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.

Availability of post-hospital services supporting community reintegration for children with identified surgical need in Uganda.

BACKGROUND: Community services and supports are essential for children transitioning home to recover from the hospital after surgery. This study assessed the availability and geographic capacity of rehabilitation, assistive devices, familial support, and school reintegration programs for school-aged children in Uganda with identified surgical need. METHODS: This study assessed the geographic epidemiology and spatial analysis of resource availability in communities in Uganda. Participants were children with identified surgical need using the Surgeons OverSeas Assessment of Surgical need (SOSAS). Community-based resources available to children and adolescents after surgery in Uganda were identified using publicly available data sources and searching for resources through consultation with in-country collaborators We sought resources available in all geographic regions for a variety of services. RESULTS: Of 1082 individuals surveyed aged 5 to 14 yearsr, 6.2% had identified surgical needs. Pediatric surgical conditions were most prevalent in the Northern and Central regions of Uganda. Of the 151 community-based services identified, availability was greatest in the Central region and least in the Northern region, regardless of type. Assuming 30% of children with surgical needs will need services, a maximum of 50.1% of these children would have access to the needed services in the extensive capacity estimates, while only 10.0% would have access in the minimal capacity estimates. The capacity varied dramatically by region with the Northern region having much lower capacity in all scenarios as compared to the Central, Eastern, or Western regions. CONCLUSIONS: Our study found that beyond the city of Kampala in the Central region, community-based services were severely lacking for school-aged children in Uganda. Increased pediatric surgical capacity to additional hospitals in Uganda will need to be met with increased availability and access to community-based services to support recovery and community re-integration.

[Dialogues on the work process in oral health in Brazil: an analysis based on the PMAQ-AB survey]. / Diálogos sobre o processo de trabalho em saúde bucal no Brasil: uma análise com base no PMAQ-AB.

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.

Los objetivos de este trabajo fueron: (1) describir el proceso de trabajo de los equipos de salud bucal (ESB) en Brasil, conforme los atributos esenciales de la atención primaria a la salud, según regiones, tipo de equipo y características socioeconómicas de los municipios; además de (2) verificar si los datos del proceso de trabajo de las ESB en el Programa Nacional de Mejora del Acceso y Calidad de la Atención Básica (PMAQ-AB) fueron capaces de evaluar tales atributos. 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.

Perceived barriers by health care providers for screening and management of excessive alcohol use in an emergency department of a low-income country.

Annually, alcohol causes 3.3 million deaths; countless more alcohol-related injury patients are treated in emergency departments (EDs) worldwide. Studies show that alcohol-related injury patients reduce their at-risk alcohol-use behavior with a brief negotiational interview (BNI) in the ED. This project aims to identify potential perceived barriers to implementing a BNI in Tanzania. A knowledge, attitude, and practice questionnaire was piloted and administered to all emergency department health care practitioners, including physicians, advanced medical officers, and nurses. The questionnaire included the Perceived Alcohol Stigma (PAS) Scale. The survey was self-administered in English, the language of health care instruction, with a Swahili translation available if preferred. Data were analyzed with relative and absolute frequencies and Spearman's correlation. Thirty-four (100%) health care practitioners completed the survey. Our results found positive attitudes toward addressing alcohol misuse (88%), but very poor knowledge of recommended alcohol-use limits (24%). Participants were willing to discuss alcohol use (88%) and to screen (71%) for alcohol-use disorders. Most health care practitioners report significant stigma against those with alcohol-use disorders (39% discrimination, 53% devaluation, 71% either). Counseling patients about high-risk alcohol use was directly and positively associated with at-risk alcohol and counseling education and believing it was common to ask patients about tobacco and alcohol use; it was negatively associated with believing it was 'not my role' or that knowing about alcohol use 'won't make a difference'. Stigma was negatively and indirectly associated with counseling patients. In conclusion, in an ED in Tanzania, health care practitioners have positive attitudes toward addressing at-risk alcohol use, and endorsed having training in alcohol misuse in school. Unfortunately, participants did not demonstrate knowledge of recommended alcohol limit guidelines. Similarly, among practitioners, there is a significant discrimination and devaluation stigma against those who misuse alcohol. These factors must be addressed prior to a successful implementation of an alcohol harm reduction intervention.

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.

Spatially balanced provision of health equipment: a cross-sectional study oriented to the identification of challenges to access promotion.

BACKGROUND: Access to health services is in part defined by the spatial distribution of healthcare equipment. To ensure equity in the provision of health services, it is important to examine availability across different health care providers taking into account population demand. Given the importance of the equitable provision of health equipment, we evaluate its spatial distribution in Brazil. METHODS: This study is classified as cross-sectional with an ecological design. We evaluate Brazilian data on distance to available health equipment considering: dialysis machines (385), magnetic resonance imaging (MRI) (257), hospital beds (3675) and bone densitometers (429). We define two distance thresholds (50 km and 200 km) from a municipality to the center of services provision. The balance between infrastructure capacity and potential demand was evaluated to identify a lack or surplus of health services. RESULTS: The distribution of dialysis equipment and bone densitometers is not balanced across Brazilian states, and unmet demand is high. With respect to MRIs, the large capacity of this equipment results in a large excess of supply. However, this characteristic alone cannot account for excesses of supply of over 700%, as is the case of the Federal District when the range is limited to 50 km. At the same time, four states in the Northeastern region of Brazil show a net excess of demand. Some regions do not meet the standard amount of supply defined by Brazilian Ministry of Health. The quantity and distribution of hospital beds are not sufficient to provide full coverage to the population. CONCLUSION: Our main focus was to evaluate the network of the provision of health equipment in Brazil, considering both private and public sectors conjointly. We take into account two main aspects of a spatially balanced health system: the regional availability of health equipment and the geographic distance between its demand and supply at the municipality level. Some regions do not meet the minimum requirement defined by the Brazilian Ministry of Health regarding the supply of health services.

Oral primary care: an analysis of its impact on the incidence and mortality rates of oral cancer.

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 (ß = 0.59; p = 0.010) and adult smokers (ß = 0.29; p = 0.010). The oral cancer related mortality rate was positively associated with the proportion of of adults over 60 years (ß = 0.24; p < 0.001) and the performance of preventative and diagnostic actions for oral cancer (ß = 0.02; p = 0.002). Mortality was inversely associated with the coverage of primary care teams (ß = -0.01; p < 0.006) and PHC financing (ß = -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.
