RESUMO

OBJECTIVE: To evaluate the impact of traditional check-up appointment on the progression of the cardiovascular risk throughout time. METHODS: This retrospective cohort study included 11,126 medical records of asymptomatic executives who were evaluated between January, 2005 and October, 2008. Variables included participants' demographics characteristics, smoking habit, history of cardiovascular diseases, diabetes, dyslipidemia, total cholesterol, HDL, triglycerides, glucose, c-reactive protein, waist circumference, hepatic steatosis, Framingham score, metabolic syndrome, level of physical activity, stress, alcohol consumption, and body mass index. RESULTS: A total of 3,150 patients was included in the final analysis. A worsening was observed in all risk factors, excepting in smoking habit, incidence of myocardial infarction or stroke and in the number of individuals classified as medium or high risk for cardiovascular events. In addition, a decrease in stress level and alcohol consumption was also seen. CONCLUSION: The adoption of consistent health policies by companies is imperative in order to reduce the risk factors and the future costs associated with illness and absenteeism.

RESUMO

Certain medicines are considered potentially inappropriate (PIM) for elderly people as they increase the risk of adverse drug events (ADE) and because safer alternative therapies are available on the market. In this context, in order to identify the instruments that assess the quality of medical prescriptions for elderly and to determine which drugs are considered PIM, a bibliographic survey was conducted in PUBMED, LILACS and PAHO databases, in February and March/2010. The search strategy included the use of health descriptors and a manual search in the references cited by selected papers. During the period of data collection, 15 instruments were identified. In 2012, with the publication of the update of Beers criteria, this instrument was included in the study. We identified 163 PIM of 25 therapeutic classes, of which 125 (76.7%) are marketed in Brazil. Of these, 31 (24.8%) are essential medicines (RENAME 2012), of which 13 have safer therapeutic equivalents and 19 (15.2%) are over-the-counter drugs. Data suggest the need for inclusion of safer alternatives for the elderly in the national list of essential medicines and the pharmaceutical care for early detection of ADE in this age group, in order to contribute to the safe use of medicines.

Determinados medicamentos são considerados potencialmente inapropriados (MPI) para idosos, por aumentarem o risco de ocorrência de eventos adversos a medicamentos (EAM) e por existirem alternativas terapêuticas mais seguras. Neste contexto, com o intuito de identificar os instrumentos que avaliam a qualidade das prescrições médicas para idosos e verificar quais medicamentos são considerados MPI, levantamento bibliográfico foi realizado nas bases de dados PUBMED, LILACS e PAHO em fevereiro e março de 2010. Para a seleção dos manuscritos utilizaram-se descritores em saúde e busca manual nas referências bibliográficas dos artigos identificados. No período da coleta de dados, foram identificados 15 instrumentos. Em 2012, com a publicação da atualização da lista de Beers, este instrumento foi incluído no estudo. Foram identificados 163 MPI de 25 classes terapêuticas, dos quais 125 (76,7%) são comercializados no Brasil. Destes, 31 (24,8%) são medicamentos essenciais (RENAME 2012), sendo que para 13 deles há equivalentes terapêuticos mais seguros e 19 (15,2%) são medicamentos isentos de prescrição. Os dados sugerem a necessidade de inclusão de medicamentos mais seguros para idosos na lista nacional de medicamentos essenciais e do monitoramento farmacoterapêutico para a detecção precoce de EAM nesta faixa etária para contribuir com o uso seguro de medicamentos.

RESUMO

The aim of the present work was to compare hepatitis C prevalence, genotypes, and risk factors between prisoners and non-prisoners in the city of Colatina, Espírito Santo, Brazil. This cross-sectional study involved approximately 1,600 residents and 730 prisoners, all of whom were living in Colatina. The percentage of individuals who tested positive for anti-HCV was 0.1% (2/1,600) in the non-prisoner group and 1.0% (7/730) in the prisoner group, confirming a higher risk of hepatitis C in the latter group. The percentage of subjects who progressed to HCV-RNA negative was 11.1% (1/9), confirming the high probability of evolution to chronicity. Genotype 1 was the most predominant genotype found. Factors associated with increased risk of hepatitis C were being male, being institutionalized, having an income of less than three minimum wages, having low educational attainment, and using injected drugs. Alcohol use, pain in the liver, migraine, and reported history of hepatitis were markedly associated with hepatitis C. The prison population tested positive for anti-HCV at a higher rate than the non-prison population.

O objetivo do presente trabalho foi comparar a prevalência, os genótipos e fatores de risco da hepatite C entre a população em geral e os presos na cidade de Colatina, Espírito Santo, Brasil. O presente estudo é transversal e comparou cerca de 1.600 moradores e 730 prisioneiros, todos eles vivendo em Colatina. A prevalência de anticorpos anti-HCV positivo foi de 0,1% (2/1.600), na população em geral, e de 1,0% (7/730) entre os presos, o que confirma o elevado risco nesse grupo. A percentagem de indivíduos que apresentam RNA-HCV negativo foi de 11,1% (1/9), confirmando a alta taxa de evolução para a cronicidade. O genótipo predominante foi o I. Fatores associados ao aumento do risco de hepatite C foram do sexo masculino, sendo institucionalizado, com renda de até três salários mínimos, baixa escolaridade e uso de drogas injetáveis. O uso de álcool, dor no fígado, enxaqueca e relato de histórias de hepatite apresentaram associação significativa com a hepatite C. A população carcerária teve maiores taxas de positividade para o anti-HCV do que a população não-prisional pesquisada.

RESUMO

OBJETIVO: Avaliar as medidas de pressão arterial comparando o método tradicional e o padrão-ouro em um serviço público de pronto atendimento. MÉTODOS: Estudo transversal no qual as medidas das pressões arteriais sistólica, diastólica, média e de pulso aferidas pelos profissionais da enfermagem pelo método tradicional foram comparadas com aquelas realizadas de acordo com o padrão-ouro. RESULTADOS: Foram incluídos 229 clientes, 69% do sexo feminino e a média de idade foi de 50 anos. A comparação entre os dois métodos mostrou que o valor médio das pressões sistólica, diastólica, média e de pulso foi maior utilizando-se a técnica padrão-ouro. CONCLUSÃO: Houve divergências entre as medidas realizadas pela técnica recomendada e pela classificação de risco.

OBJECTIVE: Evaluating arterial pressure measurements comparing the traditional and the gold standard methods in an emergency public service. METHODS: Cross-sectional study, in which arterial systolic, diastolic, mean and pulse pressure measurements obtained by nursing professionals by means of the traditional method were compared with those obtained using the gold standard technique. RESULTS: Study participants were 229 patients, 69% were women and the mean age was 50 years. The comparison between the two methods showed that the mean value of the arterial systolic, diastolic, mean and pulse pressures was higher using the gold standard technique. CONCLUSION: Divergences were found between the measurements obtained using the recommended technique and the risk classification.

RESUMO

OBJECTIVE: To evaluate the use of venous thromboembolism (VTE) prophylaxis in a general hospital. METHODS: A cross-sectional cohort study at the Hospital Nossa Senhora da Conceição, located in the city of Porto Alegre, Brazil, involving a random sample of patients admitted between October of 2008 and February of 2009. We included patients over 18 years of age and hospitalized for more than 48 h. The exclusion criteria were anticoagulant use, pregnancy, puerperium, and a history of thromboembolic disease. The adequacy of prophylaxis was evaluated in accordance with a protocol created by the Hospital and principally based on the American College of Chest Physicians guidelines, eighth edition. RESULTS: We included 262 patients. The mean age was 59.1 ± 16.6 years. The most common risk factors were immobilization (in 70.6%), infection (in 44.3%), cancer (in 27.5%), obesity (in 23.3%), and major surgery (in 14.1%). The risk of VTE was classified as high and moderate in 143 (54.6%) and 117 (44.7%) of the patients, respectively. Overall, 46.2% of the patients received adequate prophylaxis, 25% of those with > three risk factors for VTE and 18% of those with cancer, the differences between these last two groups and their counterparts (patients with < three risk factors and those without cancer) being statistically significant (p < 0.001 for both). CONCLUSIONS: Our data reveal that nearly all patients at our hospital were at risk for VTE, and that less than half received adequate VTE prophylaxis, which is in agreement with the literature. It is surprising that inadequate prophylaxis is more common in high-risk patients.

RESUMO

OBJETIVO: Avaliar a prática de profilaxia para tromboembolia venosa (TEV) em pacientes em um hospital geral. MÉTODOS: Estudo de coorte transversal conduzido no Hospital Nossa Senhora da Conceição, localizado na cidade de Porto Alegre (RS), com uma amostra constituída de pacientes internados selecionados randomicamente entre outubro de 2008 e fevereiro de 2009. Foram incluídos pacientes maiores de 18 anos e internados por mais de 48 h. Os critérios de exclusão foram pacientes em uso de anticoagulantes, história de doença tromboembólica, gestação e puerpério. A adequação da profilaxia foi avaliada seguindo as recomendações de um protocolo criado pela instituição e tendo como base principal a diretriz da American College of Chest Physician, oitava edição. RESULTADOS: Foram incluídos 262 pacientes com média de idade de 59,1 ± 16,6 anos. Os fatores de risco mais comuns foram imobilização (70,6 por cento), infecção (44,3 por cento), câncer (27,5 por cento), obesidade (23,3 por cento) e cirurgia maior (14,1 por cento). Na avaliação do nível de risco para TEV, 143 (54,6 por cento) e 117 pacientes (44,7 por cento), respectivamente, foram classificados como de risco alto e moderado. No geral, 46,2 por cento dos pacientes tiveram profilaxia adequada, assim como 25 por cento dos pacientes com três ou mais fatores de risco e 18 por cento dos pacientes com câncer, e houve diferenças estatisticamente significativas entre esses grupos quando comparados àqueles com menos de três fatores de risco e sem câncer (p < 0,001 para ambos). CONCLUSÕES: Os dados demonstram que quase a totalidade dos pacientes do hospital estava em risco para TEV e que menos da metade deles recebeu profilaxia adequada, dados esses semelhantes aos da literatura. A inadequação da profilaxia é surpreendentemente maior em pacientes de alto risco.

RESUMO

The aim of this study was to assess the level of agreement between an institutional protocol and the Manchester protocol for the risk assessment of patients attended in an emergency room of a public hospital in Belo Horizonte - MG - Brazil. This is a descriptive and comparative study, in which 382 patients' reports were evaluated and the risk was classified, using the institutional protocol and the Manchester protocol. Rates were calculated through weighted and unweighted kappa, in order to determine the level of agreement between the protocols. The results showed that the correlation between the protocols is average when considering that classification errors occurred between neighboring colors (kappa=0.48), and good when considering that classification errors occurred between extreme colors (kappa=0.61). The Manchester protocol increased the patients' level of priority of patients and has been considered more inclusive.

Este estudo teve por objetivo verificar o grau de concordância entre um protocolo institucional e o protocolo de Manchester, para a classificação de risco de pacientes atendidos no pronto-socorro de um hospital público de Belo Horizonte, MG, Brasil. Trata-se de estudo descritivo comparativo, no qual 382 prontuários foram avaliados e realizada a classificação de risco, utilizando os protocolos mencionados acima, a partir do registro realizado pelos enfermeiros. Índices Kappa ponderado e não ponderado foram calculados para determinar o grau de concordância entre os protocolos. Os resultados mostraram que a concordância entre os protocolos é média, quando considerados os erros de classificação, ocorridos entre cores vizinhas (Kappa=0,48) e boa, quando considerados os erros de classificação, ocorridos entre cores extremas (Kappa=0,61). Conclui-se que o protocolo de Manchester aumentou o nível de prioridade dos pacientes, demonstrando ser protocolo mais inclusivo.

RESUMO

Public risk perceptions of mass disasters carry considerable influences, both psychologically and economically, despite their oft-times imprecise nature. Prior research has identified the presence of an optimistic bias that affects risk perception, but there is a dearth of literature examining how these perceptions differ among cultures-particularly with regard to mass disasters. The present study explores differences among Japanese, Argentinean, and North American mental health workers in their rates of the optimistic bias in risk perceptions as contrasted between natural disasters and terrorist events. The results indicate a significant difference among cultures in levels of perceived risk that do not correspond to actual exposure rates. Japanese groups had the highest risk perceptions for both types of hazards and North Americans and Argentineans had the lowest risk perceptions for terrorism. Additionally, participants across all cultures rated risk to self as lower than risk to others (optimistic bias) across all disaster types. These findings suggest that cultural factors may have a greater influence on risk perception than social exposure, and that the belief that one is more immune to disasters compared to others may be a cross-cultural phenomenon.

RESUMO

OBJECTIVE: We investigated the hypothesis that partner-specific characteristics are important to improve an individual's risk characterization. DESIGN: It has been shown that the egocentric network structure is important to establish a person's risk for infection. METHODS: The study was cross-sectional in its design and enrolled 1231 volunteers at one HIV testing site in Rio de Janeiro, Brazil, and applied an adapted ego-network questionnaire. Each individual was interviewed about their own risk factors and those related to up to 10 sex partners. We used the dyadic data analysis method in which each relationship forms a record. Two receiver operator characteristic curves were generated, and the ability to correctly predict volunteers' HIV serostatus based on a model with characteristics of volunteers and sex partners and another with only volunteers' characteristics was evaluated. RESULTS: Partner-related variables were associated with HIV serostatus both for men and women. The model with volunteer/sex partners' characteristics performed better in discriminating between HIV-positive and negative volunteers only for men but not for women. The c statistic for men volunteers was 0.82 [95% confidence interval (CI) 0.77-0.87] for the volunteer alone model and 0.88 (95% CI 0.86-0.91) for the combined model (P = 0.03). The values for women were 0.75 (95% CI 0.65-0.86) and 0.78 (95% CI 0.71-0.85), respectively (P = 0.71). CONCLUSION: Ego-network theory-based approaches provide additional information for characterizing risk for HIV infection among men.

RESUMO

OBJECTIVE: To identify a valid neonatal mortality risk prediction score feasible for use in developing countries. STUDY DESIGN: Retrospective study of 467 neonates, < or =1500 g, enrolled in trials during 1998 to 2005 at tertiary care children's hospitals in Dhaka, Bangladesh, and Cairo, Egypt, and a community field site in Sarlahi District, Nepal. We derived simplified mortality risk scores and compared their predictive accuracy with the modified Clinical Risk Index for Babies (CRIB) II. Outcome was death during hospital stay (Dhaka and Cairo) or end of the neonatal period (Nepal). RESULTS: The area under the curve receiver operating characteristic was 0.62, 0.71, 0.68, and 0.69 on the basis of the (a) CRIB II applied to the Dhaka-Cairo dataset; (b) an 18-category, simplified age, weight, sex score; (c) a binary-risk simplified age-weight (SAW) classification derived from the Dhaka-Cairo dataset; and (d) external validation of the binary-risk SAW classification in the Nepal dataset, respectively. Mortality risk prediction with the SAW classification on the basis of gestational age (< or =29 weeks) or weight (<1000 g) was improved (P = .048) compared with CRIB II. CONCLUSIONS: The SAW classification is a markedly simplified mortality risk prediction score for use in identifying high-risk, very low birth weight neonates in developing country settings for whom urgent referral is indicated.
