Evolution of the quality of prenatal care in the primary network of Brazil from 2012 to 2018: What can (and should) improve?

The article describes the temporal evolution of prenatal quality indicators in the primary health care network in Brazil and investigates regional differences. This study used data from the external evaluation of Brazil's National Program for Improving Primary Care Access and Quality (PMAQ) with health teams participating in Cycles I, II and III of the Program, carried out respectively in 2012, 2013/14 and 2017/18. The number of visits, physical examination procedures, guidelines and request for laboratory tests were investigated. There was a positive evolution for tests-HIV, syphilis, blood glucose and ultrasound, and for all tests, guidance on feeding and weight gain of the baby and examination of the oral cavity. The indicators that performed the worst were: performance of tetanus vaccine, six or more visits, receiving guidance on exclusive breastfeeding and care for the newborn, and the procedures-all, measurement of uterine height, gynecological exam and cervix cancer prevention. These changes had a varied behavior between the regions of the country.

Prevalence of dementia and cognitive impairment with no dementia in a primary care setting in southern Brazil.

BACKGROUND: Cognitive decline is a common condition, but is still underrepresented in studies conducted in developing countries. OBJECTIVE: To calculate the prevalence of cognitive decline and depression in an elderly community-dwelling population in a city in southern Brazil. METHODS: We calculated the prevalences of dementia, cognitive impairment with no dementia (CIND) and symptoms of depression in an elderly population relying on the public healthcare system. This epidemiological study in Pelotas, Brazil, was conducted within the primary care setting. It included 299 older adults (mean age = 69.75 ± 7.6 years) who presented low levels of education (mean = 4.16 ± 3.17 years of education). They underwent cognitive screening and their medical records were analyzed. RESULTS: Among these older adults, 142 (47.5%) presented cognitive decline: 104 (34.8%) matching the cognitive criteria for CIND and 38 (12.7%) matching the cognitive criteria for dementia. Among all the individuals who completed the cognitive screening, 141 (48.4%) were positive for symptoms of depression, of whom 99 (34%) did not have any previous diagnosis in their medical records. CONCLUSION: There was high prevalence of cognitive impairment among these older adults in a primary care setting. A large number of older adults were found to have symptoms of depression without any diagnosis.

Structure for the work and composition of Family Health Support Unit teams: national survey - Program for Improving Primary Health Care Access and Quality (PMAQ), 2013. / Estrutura para o trabalho e composição de equipes do Núcleo de Apoio à Saúde da Família: pesquisa nacional - Programa de Melhoria do Acesso e da Qualidade (PMAQ), 2013.

OBJECTIVE: to describe the structure of Family Health Support Unit (FHSU) teams with regard to physical space, training received, continuing education and professionals that support Primary Health Care (PHC) teams in Brazil, in 2013. METHODS: this is a descriptive study using data from the external evaluation stage of the Program for Improving Primary Health Care Access and Quality (PMAQ). RESULTS: the 1,773 FHSU teams mainly used shared clinics at primary health care centers (85.7%); 63.4% of professionals were offered specific training when they started work at their FHSU, while 67.4% were offered continuing education; the teams received support mainly from physiotherapists (87.4%) and Physical Education professionals (87,0%). CONCLUSION: the structure available for FHSU teams is in accordance with the guidelines; some FHSU professionals have not received any specific training for the job.

Family Health Support Center: health promotion, physical activity, and chronic diseases in Brazil - national PMAQ survey 2013. / Núcleo de Apoio à Saúde da Família: promoção da saúde, atividade física e doenças crônicas no Brasil - inquérito nacional PMAQ 2013.

OBJECTIVE: to describe reported health promotion actions directed towards chronic non-communicable disease (CNCD) patients, the support of physical education professionals (PEP) and the implementation of actions to promote body practices and physical activity (BPPA) by the Family Health Support Center (FHSC) teams, according to Brazilian municipality context variables. METHODS: this was a cross-sectional study, forming part of the 2013/2014 National Primary Health Care Access and Quality Improvement Program (PMAQ), by means of interviews with FHSC professionals. RESULTS: the action most reported by the teams was evaluation and rehabilitation of psychosocial conditions (90.8%); promotion of BPPA was the sixth most performed action, and was more prevalent in the Brazilian Southeast region (89.6%), in medium-sized municipalities (88.7%), with medium human development index (HDI) (86.7%); PEP provided support to 87% of the teams. CONCLUSION: FHSC were found to make an important contribution to BPPA.

[Epidemiological and socio-demographic profile of primary care workers in the South and Northeast of Brazil]. / Perfil sócio-demográfico e epidemiológico dos trabalhadores da atenção básica à saúde nas regiões Sul e Nordeste do Brasil.

In order to describe the profile of primary health care teams in 41 municipalities with more than 100 thousand inhabitants each, a total of 4,749 health workers in two States from the South (1,730) and five from the Northeast (3,019) of Brazil were included from a sample of traditional primary care units and the Family Health Program (FHP). After providing informed consent, the health workers answered a self-applied questionnaire with demographic, work-related, and their own health-related data. The principal differences between the two models involved the structuring of the teams, with the FHP including more community health agents, more women, more young workers, fewer hired on the basis of formal admissions exams, more with a single job, more precarious employment arrangements, less employment satisfaction, less time on the job, larger workloads, greater specialization in the area, and better pay. The FHP also showed worse self-perceived health and more medical appointments. Management efforts are needed to support these workers, who form the basis of the health system and are key protagonists in the development and consolidation of primary care.

[Evaluation of the effectiveness of Primary Health Care in South and Northeast Brazil: methodological contributions]. / Avaliação de efetividade da Atenção Básica à Saúde em municípios das regiões Sul e Nordeste do Brasil: contribuições metodológicas.

The article presents the methodology used in the Baseline Study that evaluated the effectiveness of the Family Health Strategy as compared to traditional primary health care units. The study included 41 municipalities with more than 100 thousand inhabitants each, 21 from the South and 20 from the Northeast of Brazil. As the principal dependent variable and underlying premise for sampling in the Baseline Study, the effectiveness of program activities in the primary care units was analyzed in the population within the respective coverage areas, using an epidemiological survey. The health care model in the primary care units was the principal independent variable. Its effect on program activities was controlled according to geopolitical region, metropolitan area, and population size in the municipalities. Coverage of the activities was characterized according to socioeconomic, demographic, and health-related factors. The use of comparison groups, multiple-stage samples, standardized measures, adjustment for geographic and socio-demographic characteristics, and well-defined criteria for judging the findings are contributions by the methodology employed here for designing future studies to evaluate primary health care.

Health education and promotion actions among teams of the National Primary Care Access and Quality Improvement Program, Rio Grande do Sul state, Brazil. / Ações educativas e de promoção da saúde em equipes do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica, Rio Grande do Sul, Brasil.

OBJETIVO: to investigate the provision of health education and promotion actions in primary care, and their association with demographic characteristics and Family Health Strategy (FHS) coverage in Rio Grande do Sul state, Brazil. METHODS: this is a cross-sectional study conducted with 816 teams that adhered to the 2012 Primary Care Access and Quality Improvement Program. RESULTS: the most frequent actions were directed towards people with diabetes (91.2%), hypertension (90.8%) as well as antenatal and postnatal care (84.6%). The least frequent were directed to wards crack, alcohol and other drug users (32.4%), anxiolytic/benzodiazepine users (20.3%), people with tuberculosis (31.4%) and leprosy (21.0%). The greatest provision of health promotion and education actions occurred in smaller municipalities and with greater Family Health coverage. CONCLUSION: actions aimed at the reproductive period and chronic morbidities were the focus of primary care. FHS implementation strengthens health promotion.

Hospitalizations for primary care-sensitive conditions in Pelotas, Brazil: 1998 to 2012. / Hospitalizações por condições sensíveis à atenção primária em Pelotas: 1998 a 2012.

OBJECTIVE:: To verify the hospitalization trend for primary care sensitive-conditions in Pelotas, Rio Grande do Sul, Brazil from 1998 to 2012. METHODS:: An ecological study compared hospitalizations rates of the city of Pelotas with the rest of state of Rio Grande do Sul. Analysis was conducted using direct standardization of rates, coefficients were stratified by sex and the Poisson regression was used. RESULTS:: Hospitalizations for sensitive conditions decreased in Pelotas and Rio Grande do Sul. In Pelotas, a 63.8% decrease was detected in the period observed, and there was a 43.1% decrease in the state of Rio Grande do Sul. Poisson regression coefficients showed a decrease of 7% in Pelotas and of 4% in the rest of Rio Grande do Sul each year. CONCLUSION:: During the study period, several changes were introduced in the Brazilian Unified Health System ("Sistema Único de Saúde") that may have influenced the results, including changes in administration, health funding, and a complete reworking of primary care through the creation of the Family Health Strategy program ("Estratégia Saúde da Família").

[Quality of prenatal services in primary healthcare in Brazil: indicators and social inequalities]. / Qualidade da atenção pré-natal na rede básica de saúde do Brasil: indicadores e desigualdades sociais.

The aim of this study was to describe quality indicators for prenatal care in Brazil as part of the Program for the Improvement of Access and Quality (PMAQ-AB). The study analyzed number of prenatal visits, vaccination status, prescription of ferrous sulfate, physical examination, orientation, and laboratory tests, based on which a summary quality indicator was constructed. Data were collected in 2012-2013 during interviews conducted by External Evaluators of the PMAQ-AB, with 6,125 users who had done their last prenatal follow-up in Family Health units. During prenatal follow-up, 89% reported six or more visits, more than 95% received a tetanus booster and prescription of ferrous sulfate, 24% reported having received all the procedures in the physical examination, 60% received all the orientation, and 69% had all the recommended laboratory tests. Only 15% of interviewees had received adequate prenatal care, including all the recommended measures, and there was a significantly higher proportion of "complete" care in pregnant women that were older, with higher income, in the Southeast region of Brazil, in municipalities with more than 300,000 inhabitants, and in those with (HDI) in the upper quartile. There are persist social and individual inequalities that can be targeted by measures to upgrade the teams' work processes.

Diabetes Care in Brazil: Program to Improve Primary Care Access and Quality-PMAQ.

This article describes the primary health care offered to 8118 service users with diabetes in Brazil based on data from the PMAQ (Program to Improve Primary Care Access and Quality) first survey. Structure, access, service organization and management, and clinical care quality were analyzed. Prevalence of self-reported receipt of appropriate treatment was 14.3% (95% confidence interval [CI]: 13.4-15.2). Following adjustment, it was 26% higher (prevalence ratio [PR] = 1.26; 95% CI: 1.04-1.54) when primary health care centers had all the structure items investigated, it was 13% higher (PR = 1.13; 95% CI: 1.00-1.29) when the teams' work process for service organization and management was adequate and it was 14% higher (PR = 1.14; 95% CI: 1.00-1.30) when the teams' clinical practice was adequate.

[Access to medicines prescribed for acute health conditions in adults in South and Northeast Brazil]. / Acesso a medicamentos para tratamento de condições agudas prescritos a adultos nas regiões Sul e Nordeste do Brasil.

This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

Adult Physical Activity Counseling by Health Professionals in Brazil: A National Urban Population Survey.

BACKGROUND: Physical activity counseling is an attribution of health professionals. As such, this paper aims to analyze the receipt of this form of counseling. METHODS: Cross-sectional national study interviewing 12,402 adults living in the urban area of 100 Brazilian municipalities. RESULTS: Overall counseling prevalence was 30%, falling to 20% when considering only counseling provided by health professionals. Counseling was significantly more frequent among women and among individuals who were older, married, had higher socioeconomic status, were former smokers, physically active, and reporting hypertension, diabetes, and excess weight. CONCLUSIONS: Little counseling was found to be done, this being a missed opportunity for health promotion. Health services and professionals therefore need to be trained and encouraged to provide adequate information to all health service users on the benefits of leading healthy lifestyles.

Lack of access and continuity of adult health care: a national population-based survey.

OBJECTIVE To describe the lack of access and continuity of health care in adults. METHODS A cross-sectional population-based study was performed on a sample of 12,402 adults aged 20 to 59 years in urban areas of 100 municipalities of 23 states in the five Brazilian geopolitical regions. Barriers to the access and continuity of health care and were investigated based on receiving, needing and seeking health care (hospitalization and accident/emergency care in the last 12 months; care provided by a doctor, by other health professional or home care in the last three months). Based on the results obtained by the description of the sample, a projection is provided for adults living in Brazilian urban areas. RESULTS The highest prevalence of lack of access to health services and to provision of care by health professionals was for hospitalization (3.0%), whilst the lowest prevalence was for care provided by a doctor (1.1%). The lack of access to care provided by other health professionals was 2.0%; to accident and emergency services, 2.1%; and to home care, 2.9%. As for prevalences, the greatest absolute lack of access occurred in emergency care (more than 360,000 adults). The main reasons were structural and organizational problems, such as unavailability of hospital beds, of health professionals, of appointments for the type of care needed and charges made for care. CONCLUSIONS The universal right to health care in Brazil has not yet been achieved. These projections can help health care management in scaling the efforts needed to overcome this problem, such as expanding the infrastructure of health services and the workforce.

[Sexually transmitted diseases symptoms in adults: prevalence and risk factors]. / Sintomas de doenças sexualmente transmissíveis em adultos: prevalência e fatores de risco.

OBJECTIVE: To evaluate the prevalence of sexually transmitted disease (STD) symptoms and associated risk factors in an adult population. METHODS: A population-based cross-sectional study was conducted among residents of the metropolitan area of Pelotas, Brazil. Subjects were 20 years old or more. A self-administered questionnaire was used to gather information about sexual behavior and STD symptoms. Multivariate analysis was undertaken using logistic regression. RESULTS: The prevalence of STDs was 13.5%. A higher risk of STDs was found in non-white younger women with more sexual partners and who did not use condoms in their last sexual relationship. Among men, early initiation of sexual activity and anal sex were positively associated with the outcome. Higher risks were found among women with lower schooling. CONCLUSIONS: The present study identified a significant prevalence of STD symptoms in this population and showed differences in risk factors according to gender. Since many STDs are asymptomatic and symptomatic cases are often either not perceived as disease by patients or not diagnosed in health services, the actual prevalence may be even greater. The study results suggest that cohabitation with a sexual partner does not reduce the risk of STDs in this population and showed sex differences for risk factors, both of which should be taken into account while approaching this issue.

Factors associated with lack of prenatal care in a large municipality.

OBJECTIVE To analyze the factors associated with a lack of prenatal care in a large municipality in southern Brazil. METHODS In this case-control age-matched study, 716 women were evaluated; of these, 179 did not receive prenatal care and 537 received prenatal care (controls). These women were identified using the Sistema Nacional de Informação sobre Nascidos Vivos (Live Birth Information System) of Pelotas, RS, Southern Brazil, between 2009 and 2010. Multivariate analysis was performed using conditional logistic regression to estimate the odds ratios (OR). RESULTS In the final model, the variables associated with a lack of prenatal care were the level of education, particularly when it was lesser than four years [OR 4.46; 95% confidence interval (CI) 1.92;10.36], being single (OR 3.61; 95%CI 1.85;7.04), and multiparity (OR 2.89; 95%CI 1.72;4.85). The prevalence of a lack of prenatal care among administrative regions varied between 0.7% and 3.9%. CONCLUSIONS The risk factors identified must be considered when planning actions for the inclusion of women in prenatal care by both the central management and healthcare teams. These indicated the municipal areas with greater deficits in prenatal care. The reorganization of the actions to identify women with risk factors in the community can be considered to be a starting point of this process. In addition, the integration of the activities of local programs that target the mother and child is essential to constantly identify pregnant women without prenatal care.

Conclusion: FHSC were found to make an important contribution to BPPA.

Falls and self-assessment of eyesight among elderly people: a population-based study in a south Brazilian municipality.

This paper seeks to verify the association between falls and self-assessment of visual acuity in elderly people by means of a cross-sectional population-based study involving 1593 elderly people (aged 60 or over) from the urban zone of the municipality of Bagé-RS. Poisson regression was used for association analysis. Fall prevalence in the last year was 28.0% (95%CI: 25.8; 30.2), with 45.0% of these having suffered two or more falls in the same period. Elderly people self-assessing their eyesight as bad/very poor (10.0%) or regular (33.3%) showed a linear increase in fall occurrence when compared to individuals who considered their eyesight to be good/excellent. Self-assessment of eyesight showed itself to be an important factor associated with the occurrence of falls. This results entails the need to make progress with tracing elderly people with eyesight difficulties and its possible impact on actions to prevent the occurrence of falls.

[Patterns in the use of outpatient care in Brazil by patients treated through the Brazilian Unified National Health System, private health insurance, and out-of-pocket medical care]. / Padrões de utilização de atendimento médico-ambulatorial no Brasil entre usuários do Sistema Único de Saúde, da saúde suplementar e de serviços privados.

Indicators of supply, access, and use of healthcare are helpful for characterizing services, planning activities, and organizing demand. This study describes patterns of use of outpatient care and the associations with demographic and socioeconomic factors, morbidity, population size of the municipality and region, and administrative and financial classification of the provider. This was a population-based cross-sectional study with a sample of 12,402 Brazilian adults from 20 to 59 years of age living in urban areas of 100 municipalities from five regions. Prevalence of outpatient care in the three months prior to the interview was 34.6%. The Brazilian Unified National Health System (SUS) accounted for more than half (53.6%) of the cases, health insurance was used by 34% of the sample, and out-of-pocket services 12.4%, regardless of region, population size, and morbidity profile. Patterns of use of health services remain socially determined, resulting from the supply, demographic and socioeconomic characteristics, and health profile of users.

Prevalence of overweight and associated factors in under-five-year-old children in urban population in Brazil.

OBJECTIVES: To estimate the prevalence of overweight in children under five years old from urban households and to investigate associated factors. METHODS: Cross-sectional population-based study carried out in the five regions of Brazil with a sample of 6,397 children. The World Health Organization 2006 Growth Curves were used and children were considered overweight when Z-score was higher than two standard deviations of weight for height. The following variables were investigated: family income, mothers' education level, race, age, gender, number of siblings, weight at birth and duration of exclusive breastfeeding. Proportions were compared with the χ2 test and reasons of prevalence were calculated. Logistic regression was used for the adjusted analysis. RESULTS: The prevalence of overweight was of 12%. After adjustments, this prevalence was significantly higher among males (p = 0.030) and inversely proportional to the child's age (p = 0.032). White children presented 22% higher overweight prevalence than non-white ones. A linear direct association was verified between weight at birth and overweight (p = 0.000). Children who were breastfed until 120 days presented 34% more prevalence of overweight when compared to the ones who were breastfed for a longer time. CONCLUSIONS: Overweight prevalence was higher in male, under one year old, white children, with more than 3,500 grams of weight at birth and who were exclusively breastfed until 120 days.
