Abstract Background: Public programs that provide access to essential medications have played an important role in the care of hypertensive and diabetic patients. However, access in small municipalities has been poorly studied. Objectives: To describe the sociodemographic profile and the medication and health service usage of patients with systemic arterial hypertension and/or diabetes mellitus in a small municipality who use the public medication access programs Health has no Price (Saúde Não Tem Preço - SNTP) and the Minas Pharmacy Network. Methods: This cross-sectional study with 341 participants was conducted in 2019. Home interviews were conducted using a standardized, semi-structured questionnaire. The data are expressed as absolute and relative frequencies, and Pearson's chi-square test was used for comparisons between proportions (α = 5%). Results: Most of the participants (70.68%) had hypertension only, 11.14% had diabetes only, and 18.18% had both. Regarding the origin of the hypertension medications, 82.67% were provided by the Minas Pharmacy Network and/or SNTP programs. Regarding oral hypoglycemic agents and insulins, 88.61% were provided by the Minas Pharmacy Network and/or SNTP. Most participants were female (63.1%), at least 65 years of age (50.30%), non-White (66.96%), resided in an urban area (67.16%), were illiterate or had a low education level (89.94%), and had a maximum income ≤ 2 times the federal minimum salary (89.19%). Overall user perception was significantly better for SNTP (p=0.010). Conclusion: The results of this study indicate that programs which provide access to essential medications are important sources of hypertension and diabetes medications in the study area, especially for people with low incomes.

Abstract BACKGROUND: During the COVID-19 pandemic, universities have had to adopt remote education, a strategy that caused sudden changes of routine for everyone involved in academia. OBJECTIVE: To assess the profile of medicine use by the employees of a Brazilian public university during the COVID-19 pandemic. DESIGN AND SETTING: Cross-sectional study at a Brazilian public university. METHODS: Employees were invited to answer an online self-administered questionnaire, containing questions on sociodemographic features, medicine use, mental health and lifestyle habits during the COVID-19 pandemic. The outcome variable was the use of medicines stratified according to occupation. Descriptive, bivariate and multivariate (Poisson regression) statistical analyses were performed. RESULTS: A total of 372 employees participated in the study and use of medicine was reported by 53.2%. Among professors, suicide attempts (prevalence ratio [PR], 1.81; 95% confidence interval [CI], 1.20-2.74), physical activity (PR, 1.53; 95% CI, 1.11-2.11) and poor self-rated health (PR, 1.29; 95% CI, 1.01-1.66); and among technicians, decreased workload during the COVID-19 pandemic (PR, 1.41; 95% CI, 1.00-1.99), excess body weight (PR, 1.39; 95% CI, 1.02-1.88) and poor self-rated health (PR, 1.48; 95% CI, 1.14-1.92) were positively associated with use of medicines. In addition, among technicians, engaging in physical activity (PR, 0.60; 95% CI, 0.46-0.78) was a protective factor against medicine use. CONCLUSION: The profile of medicine use among these employees was similar to that of the Brazilian population. However, some associated factors may have been influenced by the COVID-19 pandemic, thus highlighting the need to examine this topic in a longitudinal study.

Abstract The action of substances with non-permeable cryoprotectant potential, besides glucose, has not yet been studied for the species Prochilodus brevis. The objective of this work was to evaluate the action of four non-permeable cryoprotectants on this species sperm cryopreservation. Five pools were cryopreserved in a solution of 5% glucose and 10% dimethyl sulfoxide (Me2SO) associated or not (control) with cryoprotectants egg yolk (5, 10 or 12%), soy lecithin (2.5, 7.5 or 10%), sucrose (5, 10 or 20%) and lactose (5, 8 or 15%). After thawing, samples were evaluated for sperm kinetics (total motility, motility duration, velocities, and wobble - WOB), morphology and membrane and DNA integrity. The treatments containing egg yolk improved significantly (P<0.05) results when compared the control for the membrane integrity parameter. When compared to other treatments, egg yolk, at any concentration, presented higher results (P<0.05) for membrane integrity, total motility, curvilinear velocity (VCL) and average path velocity (VAP) parameters. Egg yolk also showed the best results for WOB, but it did not differ from 5% and 8% lactose and 5% and 20% sucrose. Soy lecithin had the lowest percentages of morphologically normal sperm (P<0.05), while the other treatments did not differ from each other. There was no difference regarding DNA integrity data. Thus, 5% egg yolk is indicated as a non-permeable cryoprotectant for P. brevis, in association with 5% glucose and 10% Me2SO.

Resumo Nasua nasua é um carnívoro da família Procyonidae amplamente distribuído pela América do Sul. Detalhes de sua anatomia são fundamentais para a anatomia aplicada e o entendimento de sua história natural. Objetvou-se determinar a média do comprimento, largura, espessura e volume elipsoide dos rins, a média do comprimento das artérias e veias renais e revelar a esqueletopia dos rins e vasos renais em N. nasua. Para este propósito, 32 rins e os vasos renais de 16 espécimes cadavéricos (oito machos e oito fêmeas) foram dissecados e mensurados com um paquímetro digital. Os coeficientes de correlação linear de Pearson foram calculados entre o comprimento rostro-sacral e as variáveis dos rins e seus vasos. Os rins apresentaram formato de “feijão” e superfícies lisas e são unipapilados. Na média, os rins de N. nasua mediram 30x16x13 mm, sem diferença significativa entre antímeros ou sexos. O comprimento médio da artéria renal direita (1,74 ± 0,67 cm) foi maior que o da esquerda (1,26 ± 0,43 cm); o comprimento da veia renal direita (1,22 ± 0,34 cm) foi menor que o da esquerda (1,82 ± 0,46 cm) (p < 0,05). Em um macho (6,8%), foi identificada uma veia renal direita dupla como variação anatômica. Os polos craniais dos rins direito e esquerdo prevaleceram ao nível da vértebra L2, assumindo praticamente uma posição simétrica. Houve uma correlação positiva, moderada a elevada, entre o comprimento rostro-sacral com as dimensões renais e com o comprimento dos vasos renais. Os dados do presente estudo poderão vir a ser aplicados na interpretação do diagnóstico de nefropatias que cursam com alterações nas dimensões renais bem como contribuir no campo da anatomia comparada de carnívoros.

Abstract Nasua nasua is a carnivore belonging to the family Procyonidae and is widely distributed throughout South America. The details of its anatomy are fundamental to the application of antomy and understanding of its natural history. This study aimed to measure the average length, width, thickness, and volume of the kidneys; the average length of the renal artery and vein, and to describe the renal and vessel skeletopy in Nasua nasua. For this purpose, 32 kidneys and renal vessels of 16 cadaveric specimens (eight male and eight female) were dissected and measured using a digital caliper. Pearson's correlation coefficients were calculated between the rostrum-sacral length and the renal and vessel variables. The kidneys had a “bean-shaped” aspect with smooth surfaces and were unipapilate. On average, the N. nasua kidneys measured 30 × 16 × 13 mm, with no significant difference between the sexes. The average right renal artery (1.74 ± 0.67 cm) was longer than the left (1.26 ± 0.43 cm), and the right renal vein (1.22 ± 0.34 cm) was shorter than the left renal vein (1.82 ± 0.46 cm) (p < 0.05). One male animal (6.8%) presented with a double right renal vein as an anatomical variation. Both the right and left kidney cranial poles prevailed at the level of the L2 vertebra, assuming a practically symmetrical position. There was a positive and moderate to high correlation between rostrum-sacral length and renal dimensions and renal vessel lengths. The present data may be useful for interpreting the diagnosis of nephropathies that affect renal dimensions in this species and may contribute to the comparative anatomy of carnivorans.

Abstract Objective: To assess the protective effect of exclusive breastfeeding and the effectiveness of maternal vaccination in reducing pertussis-like illness. Method: This was a case-control study conducted in sentinel hospitals for pertussis in Recife between July 2016 and July 2018. Cases included children aged under six months with symptoms compatible with pertussis (pertussis-like illness). Controls included children aged under six months, living in the metropolitan region of Recife with no diagnosis of pertussis-like illness and matched by the same hospital and birth date. Results: Seventy-three cases and 194 controls were included. The diagnosis of pertussis-like illness was predominantly clinical (97,2%). Amongst the main symptoms, paroxysmal cough was observed in 95.89% of cases and vomiting in 53.4%. There were 29 hospitalized cases and no deaths. Out of the 73 cases, 47 were born to mothers vaccinated against pertussis during pregnancy, and the mothers of 144 of the 194 controls had been vaccinated. The protective effect of breastfeeding was of 74% (95% CI;38%, 89%). Children younger than six months, who were exclusively breastfed and with mothers vaccinated against pertussis during pregnancy were 5 times less likely to develop pertussis-like illness, corresponding to a protection of 79% (95% CI;31%, 94%). The effectiveness of maternal vaccination against pertussis-like illness in children under six months was low (27%) and not statistically significant (CI 95%; −34% a 60%). Conclusions: Exclusive breastfeeding protects children under six months from pertussis-like illness and may be enhanced when associated with maternal vaccination. These strategies should be encouraged because they also protect against pertussis-like illnesses.

Background: A population study is an important tool that can be used to understand the actual epidemiological scenario of the Covid-19 in different territories, identify its magnitude, understand its transmission dynamics, and its demographic, geographical, and social distribution. Objective: The aim of this study was to determine the prevalence and dynamics of SARS-CoV-2 infection in the population of two Brazilian cities during the pandemic first wave and subsequent socioeconomic and health effects. Materials &amp; methods: This paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in the population. A household survey was conducted between October and December 2020, in two historic cities of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-face interview consisted of administration of a questionnaire containing registration data, sociodemographic and economic variables, living habits, general health condition, mental health, sleep habits, and eating and nutrition. Results: We evaluated 1,762 residents, of which 764 (43.4%) were in Mariana and 998 (56.6%) in Ouro Preto. For both cities, 51.9% of the interviewees were female, with a predominance of the age range 35 to 59 years old (47.2%). The prevalence of the SARS-CoV-2 infection was 5.5% in all cities, 6.2% in Ouro Preto, and 4.7% in Mariana. The prevalence was similar between cities (P&gt;0.05). Conclusion: The study was effective in verifying the seroprevalence of infection by the virus and its findings will enable further analyses of the health conditions of the population related to social isolation and the risk of infection with SARS-CoV-2.

RESUMO Objetivo O objetivo foi avaliar a prevalência e os fatores associados aos transtornos de ansiedade em estudantes universitários de ciências da saúde da Universidade Federal de Ouro Preto, Brasil. Métodos Estudo transversal, entre março e junho de 2019. Os dados foram coletados por meio de questionário autoaplicável, incluindo questões sociodemográficas, acadêmicas, familiares e comportamentais. O Inventário de Ansiedade de Beck foi usado para avaliar a ansiedade. As estimativas foram obtidas por meio da razão de prevalência e análise multivariada de Poisson. Resultados Participaram 493 alunos com idade média de 23,1 anos e predominância do sexo feminino (79,9%). Todos os alunos apresentaram algum grau de ansiedade, sendo a frequência da forma grave, moderada e leve de 28,0%, 29,8% e 27,0%, respectivamente. Os fatores associados à ansiedade foram: ter sofrido violência psicológica e/ou física na infância, ter pensamentos suicidas, ter pai falecido, morar com os pais, ter insatisfação com o curso e estar em período de provas. Conclusões A prevalência de ansiedade foi elevada em nosso estudo e os problemas familiares anteriores ao ingresso na universidade parecem influenciar significativamente no grau de ansiedade, podendo comprometer o desempenho acadêmico e social do discente.

ABSTRACT Objective The aim was to evaluate the prevalence and factors associated with anxiety disorders among university students of health sciences at Federal University of Ouro Preto, Brazil. Methods A cross-sectional study between March to June 2019. Data were collected through a self-administered questionnaire including sociodemographic, academic, family and behavioral issues. The Beck Anxiety Inventory was used to assess anxiety. Estimates were obtained through the prevalence ratio and Poisson multivariate analysis. Results Four hundred and ninety-three students participated with a mean age of 23.1 and predominantly women (79.9%). All students had some degree of anxiety, with the frequency of the severe, moderate and mild forms being 28.0%, 29.8% and 27.0%, respectively. The factors associated with anxiety included having suffered psychological and/or physical violence in childhood, having suicidal thoughts, having a deceased parent, living with parents, being dissatisfied with the course and being in the exam period. Conclusions The prevalence of anxiety was high in our study and family problems prior to entering university seem to significantly influence the degree of anxiety, which may compromise the student’s academic and social performance.

Abstract Fruit juices are on the rise, due to the search new mixes, flavors and nutritional value. This research investigated the acceptance and sensory profile of mixed juices. Sixteen (16) mixed juices with caja, umbu, cocoa and mango flavors were studied, using acceptance and check-all-that-apply (CATA) tests in different cities (n = 226). Juices A1 and D1 had the highest scores in Porto Alegre-RS, Brazil (respectively, 7.15 and 6.91). Differently from Salvador-BA, Brazil, where the highest scores were D2 (6.76) and D3 (6.71). Using CATA, it was shown that customers in the Southern Region characterized samples differently from customers in the Northeastern Region, and the correspondence analysis, showed that consumers in Porto Alegre-RS presented different attributes than those in Salvador-BA, with respect to mixed juices and their acceptance. It is suggested the validity of the consumer data in the characterization of the sensory parameters of the mixed juices and that the familiarity with the fruit flavors interfered in the acceptance of the same.

Resumo Coelhos da raça Nova Zelândia são amplamente usados como modelos experimentais e representam uma parcela importante dos atendimentos em consultórios veterinários. A conformação músculo-esquelética dos coelhos torna frequente a ocorrência de lesões lombossacrais com comprometimento neural. Visando contribuir para a anatomia comparada e no entendimento destas lesões, foram estudadas por dissecção a origem e a distribuição dos nervos obturatórios de 30 cadáveres de coelhos da raça Nova Zelândia (15 machos e 15 fêmeas) fixados previamente em formaldeído a 10%. O nervo obturatório formou-se a partir dos ramos ventrais de L6 e L7 em 63,3% dos casos, de L5 e L6 em 13,4%, apenas de L7 em 13,4%, de L7 e S1 em 6,6% e de L6, L7 e S1 em 3,3%. O segmento espinhal que mais contribuiu para a formação do nervo foi L7 (86,6% dos nervos). Os nervos obturatórios emitiram em todos os animais, número variável de ramos para os músculos obturador interno, obturador externo, pectíneo, adutor e grácil. Não foram observadas diferenças significativas entre as frequências da origem e de ramos musculares dos nervos obturatórios quando comparados sexo e antímeros.

Abstract New Zealand rabbits are widely used as experimental models and represent an important casuistic in veterinary practices. The musculoskeletal conformation of rabbits frequently leads to the occurrence of lumbosacral lesions with neural involvement. In order to contribute to the comparative anatomy and the understanding of these lesions, the origin and distribution of the obturator nerves of 30 New Zealand rabbits (15 males and 15 females) previously fixed in 10% formaldehyde were studied by dissection. The obturator nerves were originated from the ventral spinal branches of L6 and L7 in 63.3% of the cases, L5 and L6 in 13.4%, only L7 in 13.4%, L7 and S1 in 6.6 % and of L6, L7 and S1 in 3.3%. The spinal segment that most contributed to the formation of the nerve was L7 (86.6% of the nerves). The obturator nerves emitted in all the specimens, a variable number of branches for the internal obturator, external obturator, pectineum, adductor and gracilis muscles. No significant differences were observed between the frequencies of the origin and muscular branches of the obturator nerves when comparing sex and antimers.

RESUMO OBJETIVO Caracterizar o perfil de utilização de medicamentos pelos usuários da Atenção Primária do Sistema Único de Saúde no Brasil. MÉTODOS Estudo transversal, exploratório, de natureza descritiva, integrante da Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015. Foram realizadas entrevistas com usuários presentes nos serviços por meio de questionários semiestruturados. Foram avaliadas as variáveis sociodemográficas, clínicas e relacionadas ao uso de medicamentos e verificado o uso de medicamentos nos 30 dias anteriores à entrevista. A população foi estratificada em três faixas etárias: 18 a 44, 45 a 64 e 65 anos ou mais. As diferenças entre as faixas etárias foram verificadas por meio do teste t de Student para variáveis contínuas e teste qui-quadrado para categóricas. Utilizou-se o plano de análises de amostras complexas. Os medicamentos foram classificados conforme Anatomical Therapeutical Chemical Classification System. RESULTADOS De 8.803 usuários entrevistados, 6.511 (76,2%) relataram uso de medicamentos nos 30 dias anteriores à entrevista. Em média, cada usuário utilizou 2,32 medicamentos, sem diferença entre os sexos. Dentre os usuários de medicamentos, 18,2% tinham 65 anos de idade ou mais. Em comparação com as demais faixas etárias os idosos apresentaram mais comorbidades, usaram mais medicamentos e autorrelataram pior condição de saúde; eram menos escolarizados, relataram pior situação econômica e viviam sozinhos. Os medicamentos mais utilizados foram “outros analgésicos e antipiréticos” (3º nível ATC) e losartana (5º nível ATC). CONCLUSÕES A maioria dos usuários de medicamentos possuía baixa escolaridade e comorbidades. Os medicamentos mais utilizados foram os anti-hipertensivos. A automedicação foi maior entre os jovens. A maioria dos usuários relatou utilização de medicamentos genéricos. O número médio de medicamentos e a prevalência de uso aumentaram com a idade. Devido às características observadas e as dificuldades no uso de medicamentos, os idosos estão em situação de maior vulnerabilidade.

ABSTRACT OBJECTIVE To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS). METHODS This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student’s t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System. RESULTS Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were “other analgesics and antipyretics” (3rd ATC level) and Losartan (5th ATC level). CONCLUSIONS Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics observed and the difficulties in the use of medicines, older adults are in a situation of greater vulnerability.

RESUMO OBJETIVO Caracterizar a polifarmácia em usuários da atenção primária e identificar fatores a ela associados. MÉTODOS Estudo transversal, exploratório, de natureza avaliativa, integrante do Componente Serviços da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos, 2015. A variável de interesse foi a polifarmácia, definida como o uso de cinco ou mais medicamentos. Buscou-se identificar a associação de variáveis sociodemográficas e indicadores de condições de saúde à polifarmácia. Para a comparação de grupos utilizou-se o teste qui-quadrado de Pearson. A associação entre polifarmácia e variáveis explicativas foi avaliada por modelo de regressão logística (p < 0,05). A qualidade do ajuste foi verificada pelo teste de Hosmer-Lemeshow. RESULTADOS A prevalência de polifarmácia entre os usuários de medicamentos foi de 9,4% (IC95% 7,8–12,0) na população geral e de 18,1% (IC95% 13,6–22,8) em idosos acima de 65 anos. Houve associação estatisticamente significante entre polifarmácia e faixa etária acima de 45 anos, baixa autopercepção de saúde, presença de doenças crônicas, ter plano de saúde, atendimento em serviço de emergência e região do país. Usuários do Sul apresentaram as maiores chances para polifarmácia. Os medicamentos mais utilizados foram os do aparelho cardiovascular, sendo compatível com o perfil epidemiológico nacional. CONCLUSÕES A polifarmácia é uma realidade na população atendida no âmbito da atenção primária do Sistema Único de Saúde e pode estar relacionada ao uso exacerbado ou inapropriado de medicamentos. O principal desafio para qualificar a atenção em saúde é garantir que a prescrição de múltiplos medicamentos seja apropriada e segura.

ABSTRACT OBJECTIVE To characterize the polypharmacy in primary health care patients and to identify its associated factors. METHODS This is a cross-sectional, exploratory, and evaluative study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). The variable of interest was polypharmacy, defined as the use of five or more medicines. We sought to identify the association of sociodemographic variables and indicators of health conditions to polypharmacy. For group comparison, the Pearson’s Chi-square test was used. The association between polypharmacy and explanatory variables was evaluated by logistic regression model (p < 0.05). The quality of the adjustment was verified by Hosmer-Lemeshow test. RESULTS The prevalence of polypharmacy among medicine users was 9.4% (95%CI 7.8–12.0) in the general population and 18.1% (95%CI 13.6–22.8) in older adults above 65 years old. We found statistically significant association between polypharmacy and age above 45 years, lower self-perception of health, presence of chronic diseases, having health insurance, care in emergency services, and region of the Country. South users presented the highest chances to polypharmacy. The most used medicines were those of the cardiovascular system, being compatible with the national epidemiological profile. CONCLUSIONS Polypharmacy is a reality in the population met within the primary care of Brazilian Unified Health System and may be related to excessive or inappropriate use of medicines. The main challenge to qualify health care is to ensure that prescription of multiple medicines be appropriate and safe.

RESUMO OBJETIVO Caracterizar a disponibilidade física de medicamentos traçadores nos serviços de assistência farmacêutica na atenção primária do Sistema Único de Saúde. MÉTODOS Estudo transversal de natureza avaliativa, integrante da Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015. Para a análise da disponibilidade física, foram verificados 50 itens selecionados da Relação Nacional de Medicamentos Essenciais 2012. Roteiros de observação foram aplicados nos serviços de dispensação de medicamentos na atenção primária. Foram realizadas entrevistas com usuários, profissionais de saúde e gestores municipais, por meio de questionários semiestruturados. O índice de disponibilidade foi apresentado como o percentual de unidades de saúde onde os medicamentos estavam disponíveis. Para a análise estatística foram apresentadas frequências absolutas, relativas e médias (com intervalos de 95% de confiança). A comparação de grupos foi realizada por meio dos testes Qui-quadrado de Pearson ou análise de variância, quando adequados. RESULTADOS Foram preenchidos 1.175 roteiros de observação em amostra nacional representativa composta por 273 municípios. Observaram-se diferenças estatisticamente significantes em relação ao tipo de unidade, infraestrutura e presença do profissional farmacêutico entre as regiões do Brasil. A disponibilidade média dos medicamentos traçadores na atenção primária foi de 52,9%, com diferenças entre regiões e estratos amostrais. Quando analisados todos os medicamentos, exceto os fitoterápicos, o índice elevou para 62,5%. Verificou-se disponibilidade inadequada de medicamentos para o tratamento de doenças crônicas e para doenças epidemiologicamente importantes, como a tuberculose e a sífilis congênita. CONCLUSÕES A baixa disponibilidade de medicamentos de aquisição centralizada indica possíveis deficiências na gestão da cadeia logística. As diferentes percepções sobre a disponibilidade dos medicamentos traçadores no SUS corroboram com os índices de disponibilidade geral verificados pelo estudo. Dentre os usuários, aproximadamente 60% afirmaram obter os medicamentos que necessitaram nas unidades do SUS, informação coerente com a falta de medicamentos relatada pelos responsáveis pela dispensação de medicamentos e com a avaliação dos médicos.

ABSTRACT OBJECTIVE To characterize the availability of tracer medicines in pharmaceutical services in primary health care of the Brazilian Unified Health System (SUS). METHODS This is a cross-sectional and evaluative study, part of the Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). To analyze the availability of medicines, we verified 50 items selected from the Relação Nacional de Medicamentos Essenciais (Rename – National List of Essential Medicines) of 2012. Observation scripts were applied to medicine dispensing services in the primary health care. Interviews were carried out with patients, health care professionals, and public managers, using semi-structured questionnaires. The availability index was presented as the percentage of health units where the medicines were available. For statistical analysis, absolute, relative, and mean frequencies were presented (with 95% confidence intervals). The comparison of groups was carried out by Pearson Chi-square tests or variance analysis, when needed. RESULTS One thousand, one hundred, and seventy-five observation scripts were filled in a national representative sample composed by 273 cities. Statistically significant differences were observed regarding the type of unit, infrastructure, and presence of a pharmacist between regions of Brazil. The average availability of tracer medicines in primary health care was 52.9%, with differences between regions and sampling strata. This index increased to 62.5% when phytotherapic medicines were excluded. We found limited availability of medicines for treatment of chronic and epidemiological diseases, such as tuberculosis and congenital syphilis. CONCLUSIONS The low availability of essential medicines purchased centrally by the Brazilian Ministry of Health indicates deficiencies in supply chain management. The different views on the availability of tracer medicines in SUS confirm the general availability verified in this study. Among patients, about 60% said they obtain medicines in SUS units, data consistent with the lack of medicines reported by medicine dispensers and in line with physicians’ evaluations.

RESUMO OBJETIVO Discutir fatores relacionados ao financiamento do Componente Básico da Assistência Farmacêutica no âmbito da gestão municipal do Sistema Único de Saúde. MÉTODOS A Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil – Serviços é um estudo transversal, exploratório, de natureza avaliativa, que realizou levantamento de dados em amostra estratificada pelas regiões brasileiras, consideradas diferentes populações de estudo no plano de amostragem representativa de serviços de atenção primária em municípios. Os dados foram coletados em 2015, na forma presencial mediante a aplicação de roteiros de observação direta, entrevistas com usuários, médicos e responsáveis pela entrega dos medicamentos nos serviços de atenção primária e entrevistas telefônicas com gestores municipais de saúde e responsáveis municipais pela assistência farmacêutica. Os resultados foram extraídos dos questionários aplicados por telefone. RESULTADOS Da amostra de 600 municípios elegíveis, foram coletadas 369 entrevistas (61,5%) com secretários e 507 (84,5%) com responsáveis pela assistência farmacêutica. Em 70,8% dos municípios existe sistema informatizado de gestão; e em 11,9% qualificação/capacitação dos profissionais. Mais da metade (51,3%) dos municípios receberam recursos destinados à estruturação da assistência farmacêutica, quase 60% desses municípios realizou este tipo de gastos. Em 35,4% dos casos, secretários municipais de saúde afirmaram utilizar recursos de medicamentos do Componente Básico da Assistência Farmacêutica para cobrir demandas de outros medicamentos, mas apenas 9,7% acreditam que esses recursos são suficientes para atender à demanda. A existência de comissão permanente de licitação exclusiva para a aquisição de medicamentos foi registrada em 40,0% dos municípios. CONCLUSÕES São graves as deficiências, a pouca preocupação com a formalidade na execução dos recursos públicos, os gastos ocorridos para atendimento de demandas individuais em detrimento da coletividade, a insuficiência de recursos destinados ao Componente Básico da Assistência Farmacêutica e a exaustão do modelo de financiamento.

ABSTRACT OBJECTIVE To discuss factors related to the financing of the Basic Component of Pharmaceutical Services within the municipal management of the Brazilian Unified Health System. METHODS The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil – Serviços (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services) is a cross-sectional, exploratory, and evaluative study that performed an information survey in a representative sample, stratified by Brazilian regions It considered different study populations in the sampling plan, which represent primary health care services in the cities. Data were collected in 2015 by two methods: in person, by applying direct observation scripts and interviews with users, physicians, and professionals responsible for the dispensing of medicines in primary care services; by telephone interviews with municipal health managers and municipal professionals responsible for Pharmaceutical Services. The results were extracted from the questionnaires applied by telephone. RESULTS Of the sample of 600 eligible cities, we collected 369 interviews (61.5%) with secretaries and 507 (84.5%) with pharmaceutical services managers. 70.8% of the cities have a computerized management system; and 11.9% have qualification/training of professionals. More than half (51.3%) of the cities received funds for the structuring of pharmaceutical services, and almost 60% of these cities performed this type of spending. In 35.4% of cases, municipal secretaries of health said that they use resources of medicines from the Componente Básico da Assistência Farmacêutica (CBAF – Basic Component of Pharmaceutical Services) to cover demands of other medicines, but only 9.7% believed that these funds were sufficient to cover the demands. The existence of a permanent bidding committee exclusively for acquiring medicines was reported in 40.0% of the cities. CONCLUSIONS We found serious deficiencies in the public financing of medicines, as well as little concern about the formality in the use of public resources, expenses that meet individual demands to the detriment of the community, insufficient resources allocated to the Basic Component of Pharmaceutical Services, and exhaustion of the financing model.
