A comparative analysis of outpatient costs in HIV treatment programs

OBJECTIVE: To analyze the costs of human immunodeficiency virus (HIV) outpatient treatment for individuals with different CD4 cell counts in the Brazilian public health system, and to compare to costs in other national health systems. METHODS: A retrospective survey was conducted in five public outpatient clinics of the Brazilian national HIV program in the city of São Paulo. Data on healthcare services provided for a period of one year of HIV outpatient treatment were gathered from randomly selected medical records. Prices of inputs used were obtained through market research and public sector databases. Information on costs of HIV outpatient treatment in other national health systems were gathered from the literature. Annual costs of HIV outpatient treatment from each country were converted into 2010 U.S. dollars. RESULTS: Annual cost of HIV outpatient treatment for the Brazilian national public program was US$ 2,572.92 in 2006 in São Paulo, ranging from US$ 1,726.19 for patients with CD4 cell count > 500 to US$ 3,693.28 for patients with 51 < CD4 cell count < 200. Antiretrovirals (ARVs) represented approximately 62.0% of annual HIV outpatient costs. Comparing among different health systems during the same period, HIV outpatient treatment presented higher costs in countries where HIV treatment is provided by the private sector. CONCLUSION: The main cost drivers of HIV outpatient treatment in different health systems were: ARVs, other medications, health professional services, and diagnostic exams. Nevertheless, the magnitude of cost drivers varied among HIV outpatient treatment programs due to health system efficiency. The data presented may be a valuable tool for public policy evaluation of HIV treatment programs worldwide.

Costs of most frequent nursing activities in highly dependent hospitalized patients

This quantitative study aimed to identify the costs of the most frequent nursing activities in highly dependent hospitalized patients at a medical clinic. The non-probabilistic convenience sample corresponded to 607 observations regarding oral feeding activities (OF), blood pressure verification (BP)/heart rate (HR), body temperature checking (BTC), performance of intimate hygiene and management of feeding probe. The costs identified corresponded to R$2.40 (SD+/-2.64) for OF feeding; R$1.26 (SD+/-0.48) to verify the BP/HR; R$1.17 (SD+/-0.46) for BTC; R$15.59 (SD+/-8.62) to perform intimate hygiene and R$5.95 (SD+/-2.13) for management of feeding probe. This study will facilitate cost management, with a view to avoiding waste related to unnecessary resource consumption and establish a correlation between costs and care delivery results.

Hospital costs related to streptococcal meningitis among children in Sao Jose dos Campos, Sao Paulo State, Brazil

Knowledge of hospital costs is highly important for public health decision-making. This study aimed to estimate direct hospital costs related to pneumococcal meningitis in children 13 years or younger in the city of Sao Jose dos Campos, Sao Paulo State, Brazil, from January 1999 to December 2008. Data were obtained from medical records. Hospital costs were calculated according to the mixed method for measurement of quantities of items with identified costs and value attribution to items consumed (micro-costing and gross-costing). All costs were calculated according to monetary values for November 2009 and in Brazilian currency (Real). Epi Info 3.5.1 was used for frequencies and means analysis. Forty-one cases were reported. Direct hospital costs varied from R$ 1,277.90 to R$ 19,887.56 (mean = R$ 5,666.43), or 10 to 20 times the mean cost of hospitalization for other diseases. Hospital staff labor was the highest cost, followed by medication, procedures, supplies, and lab tests.

Facoemulsificação versus extração extracapsular no sistema público de saúde: análise de custos para o hospital, para o governo e para a sociedade

OBJETIVO: Comparar custos da cirurgia de catarata em larga escala para um hospital público, para o governo e para a sociedade, pelas técnicas de facoemulsificação (FACO) e extração extracapsular (EECP). MÉTODOS: Foi realizada revisão baseada principalmente em diversos estudos clínicos realizados entre 2002 e 2010, no Centro Cirúrgico Ambulatorial do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. RESULTADOS: Os gastos estimados com os insumos utilizados para as cirurgias foram de R$ 468,92 no grupo FACO e R$ 259,96 no grupo EECP. As despesas hospitalares com o acompanhamento pós-operatório foram em média de R$ 16,40 (42%) menores no grupo FACO. Com relação ao gasto estimado para a Previdência Social, o grupo EECP custou em média, US$ 44,58 por paciente a mais que o grupo FACO. CONCLUSÃO: O incentivo e o investimento governamental para a realização da FACO no SUS são socialmente justificados, deve-se considerar também a economia dos pacientes e do sistema empresarial, bem como as vantagens clínicas para os pacientes e vantagens econômicas para os hospitais.

Custos hospitalares da meningite causada por Streptococcus pneumoniae na cidade de São José dos Campos, São Paulo, Brasil

O conhecimento dos custos hospitalares é de grande importância para os processos de tomada de decisão em saúde pública. O objetivo deste estudo foi estimar os custos hospitalares diretos relacionados à meningite pneumocócica em crianças com até 13 anos (inclusive), na cidade de São José dos Campos, São Paulo, Brasil, de janeiro de 1999 a dezembro de 2008. Foram obtidos dados de prontuários médicos. O cálculo foi realizado pelo método misto de mensuração das quantidades dos itens de custos e atribuição de valor aos itens consumidos (micro-costing e gross-costing). Os valores monetários referem-se a novembro de 2009, sendo expressos em reais. A análise das frequências e médias foi realizada pelo programa Epi Info versão 3.5.1. Foram notificados 41 casos. Os custos hospitalares diretos variaram de R$ 1.277,90 a R$ 19.887,56 (média = R$ 5.666,43), ou seja, 10 a 20 vezes maiores que o custo médio de internações pago pelo SUS. Os custos dos honorários profissionais foram os mais relevantes, seguidos pelos custos dos medicamentos, procedimentos, materiais e exames laboratoriais.

Custos da cadeia de procedimentos no tratamento do infarto agudo do miocárdio em hospitais brasileiros de excelência e especializados

OBJETIVO: Apresenta a metodologia e os resultados de uma pesquisa de campo para avaliar os custos da cadeia de procedimentos para tratamento do Infarto Agudo do Miocárdio (IAM), realizada em 11 hospitais brasileiros de excelência e especializados. MÉTODOS: A apuração do custo utilizou o sistema de custo por procedimento e o sistema por patologia. Os procedimentos associados ao tratamento do IAM foram organizados com sua sequência lógica (protocolos), dando origem a um fluxograma. Os instrumentos de coleta da pesquisa contemplavam informações relativas aos preços e as quantidades (particular, convênios, tabela SUS e Associação Médica Brasileira - AMB), praticados no ano de 2008, bem como os custos pertinentes. RESULTADOS: De forma geral, o custo total dos procedimentos que integram o "tratamento-padrão" do IAM, totalizou R$ 12.873,69 se a intervenção coronária percutânea (ICP) não envolver utilização de stent. Caso este se torne necessário, o custo se eleva para R$ 23.461,87. CONCLUSÃO: Entre os resultados obtidos destacam-se: o fato de os valores dos procedimentos mais caros não apresentarem variações estatísticas significativas entre os hospitais, independentemente de sua localização, clientela predominante ou natureza jurídica; e o fato de os hospitais, que tratam predominantemente de usuários do Sistema Único de Saúde, registrar custos menores, mas não estatisticamente significativos, para toda a cadeia de procedimentos associada à patologia.

Tamanho de amostra e estimativa de custo em levantamento epidemiológico de cárie dentária

O objetivo do presente estudo foi analisar como a prevalência e a distribuição da cárie dentária influenciam o tamanho da amostra em levantamentos epidemiológicos, e os custos para sua realização. Foram utilizados dados de levantamentos realizados em escolares de 12 anos em Bauru nos anos de 1976, 1984, 1990, 1994 e 2001, e em Piracicaba nos anos de 2001 e 2005. Os tamanhos amostrais foram dimensionados considerando-se a média e o desvio padrão obtidos, fixando-se erro amostral em 1%, 2%, 5% e 10%. Os custos foram estimados considerando material permanente, de consumo e recursos humanos. Verificou-se aumento no tamanho das amostras em ambos os municípios, variando de 119 em 1976 para 1.118 em 2001 em Bauru, e de 954 em 2001 para 1.252 em 2005 em Piracicaba, considerando-se um erro amostral de 10%. Considerando-se diferentes erros amostrais, verificou-se o custo para o levantamento, sendo que o mesmo depende do quanto o pesquisador se permite errar em relação ao verdadeiro valor da média da população. Conclui-se que a diminuição da prevalência da cárie dentária determinou o aumento no tamanho das amostras e a elevação dos custos para realização dos levantamentos.

Costs and benefits of freezing behaviour in the harvestman Eumesosoma roeweri (Arachnida, Opiliones)

Animals present an enormous variety of behavioural defensive mechanisms, which increase their survival, but often at a cost. Several animal taxa reduce their chances of being detected and/or recognized as prey items by freezing (remaining completely motionless) in the presence of a predator. We studied costs and benefits of freezing in immature Eumesosoma roeweri (Opiliones, Sclerosomatidae). Preliminary observations showed that these individuals often freeze in the presence of the syntopic predatory spider Schizocosa ocreata (Araneae, Lycosidae). We verified that harvestmen paired with predators spent more time freezing than when alone or when paired with a conspecific. Then. we determined that predator chemical cues alone did not elicit freezing behaviour. Next, we examined predator behaviour towards moving/non-moving prey and found that spiders attacked moving prey significantly more, suggesting an advantage of freezing in the presence of a predator. Finally, as measure of the foraging costs of freezing, we found that individuals paired with a predator for 2 h gained significantly less weight than individuals paired with a conspecific or left alone. Taken together, our results suggest that freezing may protect E. roeweri harvestmen from predatory attacks by wolf spiders, but at the cost of reduced food and/or water intake. (C) 2009 Elsevier B.V.

High-Performance Liquid Chromatography Under Partially Denaturing Conditions (dHPLC) is a Fast and Cost-Effective Method for Screening Molecular Defects: Four Novel Mutations Found in X-Linked Chronic Granulomatous Disease

Implementing precise techniques in routine diagnosis of chronic granulomatous disease (CGD), which expedite the screening of molecular defects, may be critical for a quick assumption of patient prognosis. This study compared the efficacy of single-strand conformation polymorphism analysis (SSCP) and high-performance liquid chromatography under partially denaturing conditions (dHPLC) for screening mutations in CGD patients. We selected 10 male CGD patients with a clinical history of severe recurrent infections and abnormal respiratory burst function. gDNA, mRNA and cDNA samples were prepared by standard methods. CYBB exons were amplified by PCR and screened by SSCP or dHPLC. Abnormal DNA fragments were sequenced to reveal the nature of the mutations. The SSCP and dHPLC methods showed DNA abnormalities, respectively, in 55% and 100% of the cases. Sequencing of the abnormal DNA samples confirmed mutations in all cases. Four novel mutations in CYBB were identified which were picked up only by the dHPLC screening (c.904 insC, c.141+5 g>t, c.553 T>C, and c.665 A>T). This work highlights the relevance of dHPLC, a sensitive, fast, reliable and cost-effective method for screening mutations in CGD, which in combination with functional assays assessing the phagocyte respiratory burst will contribute to expedite the definitive diagnosis of X-linked CGD, direct treatment, genetic counselling and to have a clear assumption of the prognosis. This strategy is especially suitable for developing countries.

Costs and benefits of temporary brood desertion in a Neotropical harvestman (Arachnida: Opiliones)

Brood desertion is a life history strategy that allows parents to minimize costs related to parental care and increase their future fecundity. The harvestman Neosadocus maximus is an interesting model organism to study costs and benefits of temporary brood desertion because females abandon their clutches periodically and keep adding eggs to their clutches for some weeks. In this study, we tested if temporary brood desertion (a) imposes a cost to caring females by increasing the risk of egg predation and (b) offers a benefit to caring females by increasing fecundity as a result of increased foraging opportunities. With intensive field observations followed by a model selection approach, we showed that the proportion of consumed eggs was very low during the day and it was not influenced by the frequency of brood desertion. The proportion of consumed eggs was higher at night and it was negatively related to the frequency of brood desertion. However, frequent brood desertion did not result in higher fecundity, measured both as the number of eggs added to the current clutch and the probability of laying a second clutch over the course of the reproductive season. Considering that harvestmen are sensitive to dehydration, brood desertion during the day may attenuate the physiological stress of remaining exposed on the vegetation. Moreover, since brood desertion is higher during the day, when egg predation pressure is lower, caring females could be adjusting their maternal effort to the temporal variation in predation risk, which is regarded as the main cost of brood desertion in ectotherms.

Radiation therapy for Graves' ophthalmopathy: a systematic review and meta-analysis of randomized controlled trials

PURPOSE: To evaluate the efficacy of radiotherapy (RT) with total dose of 20 Gy (RT 20 Gy) in the treatment of Graves' ophthalmopathy. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical treatments for Graves' ophthalmopathy. The MEDLINE, EMBASE, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. RESULTS: A total of 8 randomized controlled trials (439 patients) were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85-250, p=0.04), RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.59-6.23, p=0.003) and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, p=0.01). There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. CONCLUSION: Our data have shown that RT 20 Gy should be offered as a valid therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs.
