A retrospective cohort study of Acticoat™ versus Silvazine™ in a paediatric population

We wished to determine whether changing our centre's practice of using Acticoat instead of Silvazine as our first-line burns dressing provided a better standard of care in terms of efficacy, cost and ease of use. A retrospective cohort study was performed examining 328 Silvazine treated patients from January 2000 to June 2001 and 241 Acticoat treated patients from July 2002 to July 2003. During those periods the respective dressings were used exclusively. There was no significant difference in age, %BSA and mechanism of burn between the groups. In the Silvazine group, 25.6% of children required grafting compared to 15.4% in the Acticoat group (p=0.001). When patients requiring grafting were excluded, the time taken for re-epithelialisation in the Acticoat group (14.9 days) was significantly less than that for the Silvazine group (18.3 days), p=0.047. There were more wounds requiring long term scar management in the Silvazine group (32.6%) compared to the Acticoat group (29.5%), however this was not significant. There was only one positive blood culture in each group, indicating that both Silvazine and Acticoat are potent antimicrobial agents. The use of Acticoat as our primary burns dressing has dramatically changed our clinical practice. Inpatients are now only 18% of the total admissions, with the vast majority of patients treated on an outpatient basis. In terms of cost, Acticoat was demonstrated to be less expensive over the treatment period than Silvazine . We have concluded that Acticoat is a safe, cost-effective, efficacious dressing that reduces the time for re-epithelialisation and the requirement for grafting and long term scar management, compared to Silvazine.

Connecting the person with dementia and family : a feasibility study of a telepresence robot

Background Maintenance of communication is important for people with dementia living in long-term care. The purpose of this study was to assess the feasibility of using “Giraff”, a telepresence robot to enhance engagement between family and a person with dementia living in long-term care. Methods A mixed-methods approach involving semi-structured interviews, call records and video observational data was used. Five people with dementia and their family member participated in a discussion via the Giraff robot for a minimum of six times over a six-week period. A feasibility framework was used to assess feasibility and included video analysis of emotional response and engagement. Results Twenty-six calls with an average duration of 23 mins took place. Residents showed a general state of positive emotions across the calls with a high level of engagement and a minimal level of negative emotions. Participants enjoyed the experience and families reported that the Giraff robot offered the opportunity to reduce social isolation. A number of software and hardware challenges were encountered. Conclusions Participants perceived this novel approach to engage families and people with dementia as a feasible option. Participants were observed and also reported to enjoy the experience. The technical challenges identified have been improved in a newer version of the robot. Future research should include a feasibility trial of longer duration, with a larger sample and a cost analysis.

Strengthening local road safety capacity in Cambodia

Road crashes and injuries have become a growing issue worldwide. In 2011, more than 75,000 people died in road crashes in the ten member countries of the Association of South East Asian Nations (ASEAN) and many times this number sustained long term injuries. In 2014, the Asian Development Bank (ADB), funded by the Japan Fund for Poverty Reduction, commenced a package of actions to improve road safety in ASEAN. In 2015, as part of the technical assistance for this project, a Road Safety Advisor was appointed for Cambodia for four months. The assignment produced several primary outputs, which included the organization of national training on traffic law enforcement and road safety management, the conduct of a training needs survey and cost analysis study, and the development of a proposal for strengthening speed management. It is important to note that unlike other ADB technical assistance projects, this assignment adopted a capacity building approach, which promoted and encouraged the local road safety team in the government to step up and take action. The research capacity building approach adopted in this project highlighted the feasibility of increasing participation from existing stakeholders, especially the government in identifying existing human resources, building the capacity of relevant government officials and supporting them to take the ownership of the project. It is hoped that similar outcomes will occur in the other ASEAN countries.

ShadowBoxer and LocusEater: programs to optimise experimental design and multiplexing strategies for genetic mark-recapture

Genetic mark–recapture requires efficient methods of uniquely identifying individuals. 'Shadows' (individuals with the same genotype at the selected loci) become more likely with increasing sample size, and bias harvest rate estimates. Finding loci is costly, but better loci reduce analysis costs and improve power. Optimal microsatellite panels minimize shadows, but panel design is a complex optimization process. locuseater and shadowboxer permit power and cost analysis of this process and automate some aspects, by simulating the entire experiment from panel design to harvest rate estimation.

Change to costs and lengths of stay in the emergency department and the Brisbane protocol: An observational study

- Objective To compare health service cost and length of stay between a traditional and an accelerated diagnostic approach to assess acute coronary syndromes (ACS) among patients who presented to the emergency department (ED) of a large tertiary hospital in Australia. - Design, setting and participants This historically controlled study analysed data collected from two independent patient cohorts presenting to the ED with potential ACS. The first cohort of 938 patients was recruited in 2008–2010, and these patients were assessed using the traditional diagnostic approach detailed in the national guideline. The second cohort of 921 patients was recruited in 2011–2013 and was assessed with the accelerated diagnostic approach named the Brisbane protocol. The Brisbane protocol applied early serial troponin testing for patients at 0 and 2 h after presentation to ED, in comparison with 0 and 6 h testing in traditional assessment process. The Brisbane protocol also defined a low-risk group of patients in whom no objective testing was performed. A decision tree model was used to compare the expected cost and length of stay in hospital between two approaches. Probabilistic sensitivity analysis was used to account for model uncertainty. - Results Compared with the traditional diagnostic approach, the Brisbane protocol was associated with reduced expected cost of $1229 (95% CI −$1266 to $5122) and reduced expected length of stay of 26 h (95% CI −14 to 136 h). The Brisbane protocol allowed physicians to discharge a higher proportion of low-risk and intermediate-risk patients from ED within 4 h (72% vs 51%). Results from sensitivity analysis suggested the Brisbane protocol had a high chance of being cost-saving and time-saving. - Conclusions This study provides some evidence of cost savings from a decision to adopt the Brisbane protocol. Benefits would arise for the hospital and for patients and their families.

Costs and Benefits of a Shared Digital Long-Term Preservation System

This paper describes the cost-benefit analysis of digital long-term preservation (LTP) that was carried out in the context of the Finnish National Digital Library Project (NDL) in 2010. The analysis was based on the assumption that as many as 200 archives, libraries, and museums will share an LTP system. The term ‘system’ shall be understood as encompassing not only information technology, but also human resources, organizational structures, policies and funding mechanisms. The cost analysis shows that an LTP system will incur, over the first 12 years, cumulative costs of €42 million, i.e. an average of €3.5 million per annum. Human resources and investments in information technology are the major cost factors. After the initial stages, the analysis predicts annual costs of circa €4 million. The analysis compared scenarios with and without a shared LTP system. The results indicate that a shared system will have remarkable benefits. At the development and implementation stages, a shared system shows an advantage of €30 million against the alternative scenario consisting of five independent LTP solutions. During the later stages, the advantage is estimated at €10 million per annum. The cumulative cost benefit over the first 12 years would amount to circa €100 million.

Adapting to climate change: Combining economics and geomorphology in coastal policy

How is climate change affecting our coastal environment? How can coastal communities adapt to sea level rise and increased storm risk? These questions have garnered tremendous interest from scientists and policy makers alike, as the dynamic coastal environment is particularly vulnerable to the impacts of climate change. Over half the world population lives and works in a coastal zone less than 120 miles wide, thereby being continuously affected by the changes in the coastal environment [6]. Housing markets are directly influenced by the physical processes that govern coastal systems. Beach towns like Oak Island in North Carolina (NC) face severe erosion, and the tax assesed value of one coastal property fell by 93% in 2007 [9]. With almost ninety percent of the sandy beaches in the US facing moderate to severe erosion [8], coastal communities often intervene to stabilize the shoreline and hold back the sea in order to protect coastal property and infrastructure. Beach nourishment, which is the process of rebuilding a beach by periodically replacing an eroding section of the beach with sand dredged from another location, is a policy for erosion control in many parts of the US Atlantic and Pacific coasts [3]. Beach nourishment projects in the United States are primarily federally funded and implemented by the Army Corps of Engineers (ACE) after a benefit-cost analysis. Benefits from beach nourishment include reduction in storm damage and recreational benefits from a wider beach. Costs would include the expected cost of construction, present value of periodic maintenance, and any external cost such as the environmental cost associated with a nourishment project (NOAA). Federal appropriations for nourishment totaled $787 million from 1995 to 2002 [10]. Human interventions to stabilize shorelines and physical coastal dynamics are strongly coupled. The value of the beach, in the form of storm protection and recreation amenities, is at least partly capitalized into property values. These beach values ultimately influence the benefit-cost analysis in support of shoreline stabilization policy, which, in turn, affects the shoreline dynamics. This paper explores the policy implications of this circularity. With a better understanding of the physical-economic feedbacks, policy makers can more effectively design climate change adaptation strategies. (PDF contains 4 pages)

Gestão estratégica de custos: estudos de casos de empresas industriais do setor de construção naval, localizadas no Estado do Rio de Janeiro

A competição atualmente vivida pelas organizações tem despertado o interesse em desenvolver formas de superar a concorrência e com isso, prosperar no mercado. Uma das formas de superar a concorrência é gerir os custos de forma estratégica para que seja possível superar a concorrência. A gestão estratégica de custos tem por finalidade ampliar os horizontes da análise de custos, ou seja, ela visa cobrir as deficiências existentes nos sistemas tradicionais de custeio, pois em sua análise irá considerar a cadeia de valor como um todo e não somente os processos internos em que há agregação de valor por parte da empresa. Assim, o objetivo da presente pesquisa foi investigar as características dos sistemas de custos e como as empresas da indústria de construção naval do Estado do Rio de Janeiro estão utilizando informações de custos para dar suporte à gestão estratégica, procurando investigar aspectos relativos a esta prática; assim, tem-se como propósito verificar a aplicação da teoria no setor. Para isso, foram realizados estudos casos em cinco empresas da indústria de construção naval, as empresas estudadas, constituem uma amostra não probabilística, ou seja, amostra por acessibilidade. O estudo constatou que mesmo às empresas não utilizando o método de custeio recomendando pela literatura, é dada uma especial atenção nas transações ocorridas ao longo da cadeia de valor, o que permite gerir os custos de maneira eficiente. Isso mostra a proximidade de diversas ações tomadas pelas empresas estudadas e a literatura sobre gestão estratégica de custos

Análise de custo de um programa de prevenção de internação para idosos no ambiente da saúde suplementar

Esta tese realiza uma análise de custo de um programa de prevenção de internação hospitalar para idosos (acima de 65 anos), no ambiente da saúde suplementar. Trata-se um programa voltado para idosos considerados de risco, de acordo com um questionário que avalia a probabilidade de risco de internação hospitalar. Indivíduos de risco são convidados a participar do programa, quando se estabelecem dois grupos: um que aceita a intervenção do programa (Grupo Bem Viver) e outro que recusa (Grupo Recusa). A intervenção do programa está voltada para o acompanhamento domiciliar, com equipe multidisciplinar, que se efetiva de acordo com uma estratificação, segundo a avaliação da dependência funcional para os indivíduos. Essa estratificação funcional divide os idosos do programa em cinco grupos distintos, denominados grupos funcionais. Indivíduos que recusam a intervenção mantêm a assistência com cuidado usual. A análise de custo é uma avaliação econômica parcial que estabelece uma comparação da utilização de serviços de saúde entre os dois grupos de idosos: um sob intervenção, grupo Bem Viver, e outro em cuidado usual, grupo Recusa. Esta análise foi realizada para um período dividido em 12 meses antes do evento (intervenção ou recusa) e 12 meses após o evento. Levantou-se a utilização de serviços de saúde de acordo com os indicadores de consultas, exames, procedimentos ambulatoriais, internações e consultas hospitalares. O custo do programa foi incluído também na análise final. Comparações foram estabelecidas entre os grupos no padrão de utilização, considerando-se os períodos antes e depois do evento. Os grupos funcionais foram analisados dentro da perspectiva da utilização para os mesmos períodos. Os resultados demonstraram que o grupo com adesão tem um grande percentual de indivíduos com dependência funcional, sugerindo que existe uma seleção adversa na aceitação do programa, quando indivíduos de maior risco têm adesão. Para o grupo sob intervenção, ocorreu um aumento da utilização com os serviços de saúde no conjunto de consultas, exames e procedimentos ambulatoriais, havendo diminuição com o custo unitário das internações hospitalares e consultas hospitalares. O grupo que recusa tem discreto aumento para o conjunto de consultas, exames e procedimentos ambulatoriais e um grande percentual de aumento para as internações (+40.2%) e consultas hospitalares (34.3%). Este resultado para internações foi analisado também através da transformação logarítmica, com uso da função inversa para a base de cálculo. Nesta aplicação estatística foi confirmado esse resultado para o padrão de utilização de internações. Na análise final, que incluiu o custo do programa propriamente dito, foi apresentada uma hipótese de avaliação para o grupo Bem Viver, sem a intervenção do programa. Desta maneira, realizou-se uma projeção para a utilização do grupo Bem Viver, a partir dos percentuais atingidos pelo grupo Recusa.

Avaliação do comportamento estrutural de subestações de energia elétrica com o uso do aço inoxidável.

A crescente utilização do aço inoxidável como elemento estrutural despertou o interesse de clientes, arquitetos e engenheiros nos últimos anos. Apesar do custo ainda elevado, a sua aplicação na construção civil vem substituindo outros elementos estruturais. Seja por sua alta resistência à corrosão, aumentando a relação custo benefício; sua estética, proporcionando formas cada vez mais ousadas ou; seu apelo ambiental, gerando menos resíduos no meio ambiente. As subestações representam um papel importante no fornecimento de energia. Como possuem grande complexidade para manutenção, foi escolhida a estrutura suporte de seu barramento, para o dimensionamento em aço inoxidável. Desta forma, minimizando as paradas para realização de manutenções das estruturas, possibilitando maior qualidade no fornecimento de energia elétrica. Para fins comparativos foi escolhido o projeto de uma SE existente, cuja estrutura de suporte do barramento, foi construída por treliças formadas por cantoneiras de aço carbono galvanizado. Inicialmente, o dimensionamento foi desenvolvido utilizando perfis H e I funcionando como viga-coluna para os dois tipos de aço. Num segundo momento, a estrutura foi dimensionada como treliças planas. Todos os dimensionamentos foram realizados de acordo com as prescrições normativas do EUROCODE 3. Após realização dos dimensionamentos, foram apresentadas as análises comparativas dos custos envolvidos para os tipos de aço. Abordando o investimento inicial, os gastos com manutenção ao longo da vida e os custos elétricos agregados à redução das paradas para manutenção.

Acidentes de motocicleta em Paranavaí-PR: uma análise para o Sistema Único de Saúde e para o DPVAT

O presente trabalho visa caracterizar os acidentes com envolvimento de motocicletas no perímetro urbano de Paranavaí-PR, em 2007, e estimar o impacto econômico das internações advindas destes, na perspectiva do Sistema Único de Saúde (SUS) e para o Seguro obrigatório que cobre danos pessoais causados por veículos automotores de via terrestre (DPVAT). Trata-se de um estudo transversal, retrospectivo, que se baseia em buscas e análises das bases de dados do Serviço integrado de atendimento ao trauma e emergência (SIATE), do DPVAT e do Sistema de informações sobre internações do SUS (SIH-SUS), com vias a análise das variáveis: gênero, idade, tipo de acidente, condição da vítima no acidente, mês da ocorrência, gravidade, frequência de internação hospitalar, custo, componentes de custo, óbitos e tempo médio de permanência no SUS. A busca ocorreu, primeiramente, no sistema do SIATE para conhecer todos os acidentados com envolvimento de motocicletas no perímetro urbano de Paranavaí, no ano de 2007. De posse desses nomes, as buscas seguintes ocorreram no sistema interno do DPVAT e no SIH-SUS. O profissional do SIATE, no momento da abordagem da ocorrência julga a gravidade da vítima conforme códigos, sendo 1 para ferimentos leves, 2 para graves sem risco à vida, 3, graves com risco à vida e 4, os óbitos. A população estudada constou de 655 vítimas (440 homens e 215 mulheres), com média de idade de 29,5 anos, sendo que 598 (91,3%) saíram lesionadas e 11 (1,7%) vieram a óbito. O condutor de motocicleta foi o mais acometido e o tipo de acidente mais comum aconteceu entre um automóvel e uma motocicleta. Com relação à frequência da internação hospitalar (pelo SUS, DPVAT ou ambos), foi, em média, de 27% (177 de 655). Do total de vítimas internadas verificou-se que 106 tiveram cobertura do DPVAT, 58 do SUS e 13 de ambos. As internações pelo DPVAT geraram um custo total de R$ 191.423,43, custo médio de R$ 1.608,60 por internação. Com relação aos custos das internações do SUS, os referidos acidentes geraram o pagamento de R$ 42.342,20, perfazendo a média de R$ 450,44 por AIH e de R$ 596,37 por paciente. O custo médio da internação dos acidentes de trânsito com envolvimento de motocicletas foi de R$ 1.321,00, sendo que para o código 1 foi de R$ 885,00, para o código 2 de R$ 1.377,00 e para o código 3 de R$ 2.034,00. Portanto, foi possível caracterizar os acidentes e chegar a estimativas de quanto se gasta com as internações advindas destes, além disso, este é um indicativo claro da necessidade de adotar políticas públicas que priorizem a aplicação dos recursos financeiros e humanos na redução dos acidentes e da sua gravidade.

Programa Aqui tem Farmácia Popular: expansão entre 2006-2012 e comparação com os custos da assistência farmacêutica na Secretaria Municipal de Saúde do Rio de Janeiro

Em 2004 o governo federal anunciou um novo mecanismo para melhorar o acesso da população brasileira aos medicamentos, chamado de "Programa Farmácia Popular do Brasil" (PFPB) que disponibiliza um rol de produtos subsidiados pelo governo, utilizando ou não sistema de copagamento. O PFPB está dividido em três vertentes: (a) no setor público, chamada Rede Própria; (b) expansão em 2006, com o comércio farmacêutico denominado "Aqui Tem Farmácia Popular" (ATFP) e; (c) isenção de copagamento, em 2011, em todas as farmácias no âmbito do Programa, para anti-hipertensivos, antidiabéticos e antiasmáticos. Este estudo examinou o modelo de provisão de medicamentos na versão ATFP, comparando-o ao tradicionalmente praticado na Secretaria Municipal de Saúde do Rio de Janeiro (SMS-Rio), com vistas a avaliar seus custos para os setores públicos envolvidos. Foram levantados os gastos do Ministério da Saúde (MS) com pagamentos no Programa ATFP em fontes secundárias, como o Fundo Nacional de Saúde e a Sala de Apoio à Gestão Estratégica, de 2006 a 2012. Dados sobre o volume de pagamentos por medicamentos, perfil dos usuários atendidos e unidades farmacotécnicas (UF) dispensadas foram mapeados por contato direto com o Sistema Eletrônico do Serviço de Informações ao Cidadão. Estimativas dos custos da SMS-Rio, com aquisição, logística e dispensação de 25 medicamentos, restritas ao ano de 2012, foram realizadas. No período ocorreu forte expansão do Programa ATFP, tanto de unidades credenciadas, como de municípios cobertos, de 750% e 528%, respectivamente. Gastos federais com medicamentos no ATFP foram de aproximadamente R$ 3,4 bilhões, em valores ajustados para 31/12/2012. Houve inversão do fluxo dos pagamentos para entidades com matriz fora das capitais, representando aumento da capilaridade do Programa, e relativa concentração de pagamentos em grandes redes varejistas. No município do Rio de Janeiro, estes gastos foram superiores a R$ 260 milhões e, desde 2008, são maiores que as transferências do MS para aquisição de medicamentos básicos. Custos comparativos entre o menor Valor de Referência (VR) do Programa ATFP, e o custo estimado por UF na SMS-Rio dos medicamentos mostrou-se, na média geral, quase 255% vezes maior que o custo municipal. A comparação de custo foi mais favorável à SMS-Rio em 20 dos 25 itens comuns. Simulação considerando a demanda de cada medicamento consumido pela SMS-Rio em 2012 mostrou que, se a municipalidade os adquirisse pelo menor VR, incorreria em mais de R$ 95 milhões no custo global para os mesmos 25 produtos. O programa ministerial representou melhoria no acesso a medicamentos, mas os gastos expressivos repercutem em sua interface com o sistema descentralizado de financiamento da assistência farmacêutica. Alguns dos VR poderiam ser objetos de exame e avaliação, frente aos custos sistematicamente mais favoráveis nos valores levantados para a SMS-Rio.

Economic valuation of natural resources: a handbook for coastal resource policymakers

Professionals who are responsible for coastal environmental and natural resource planning and management have a need to become conversant with new concepts designed to provide quantitative measures of the environmental benefits of natural resources. These amenities range from beaches to wetlands to clean water and other assets that normally are not bought and sold in everyday markets. At all levels of government — from federal agencies to townships and counties — decisionmakers are being asked to account for the costs and benefits of proposed actions. To non-specialists, the tools of professional economists are often poorly understood and sometimes inappropriate for the problem at hand. This handbook is intended to bridge this gap. The most widely used organizing tool for dealing with natural and environmental resource choices is benefit-cost analysis — it offers a convenient way to carefully identify and array, quantitatively if possible, the major costs, benefits, and consequences of a proposed policy or regulation. The major strength of benefit-cost analysis is not necessarily the predicted outcome, which depends upon assumptions and techniques, but the process itself, which forces an approach to decision-making that is based largely on rigorous and quantitative reasoning. However, a major shortfall of benefit-cost analysis has been the difficulty of quantifying both benefits and costs of actions that impact environmental assets not normally, nor even regularly, bought and sold in markets. Failure to account for these assets, to omit them from the benefit-cost equation, could seriously bias decisionmaking, often to the detriment of the environment. Economists and other social scientists have put a great deal of effort into addressing this shortcoming by developing techniques to quantify these non-market benefits. The major focus of this handbook is on introducing and illustrating concepts of environmental valuation, among them Travel Cost models and Contingent Valuation. These concepts, combined with advances in natural sciences that allow us to better understand how changes in the natural environment influence human behavior, aim to address some of the more serious shortcomings in the application of economic analysis to natural resource and environmental management and policy analysis. Because the handbook is intended for non-economists, it addresses basic concepts of economic value such as willingness-to-pay and other tools often used in decision making such as costeffectiveness analysis, economic impact analysis, and sustainable development. A number of regionally oriented case studies are included to illustrate the practical application of these concepts and techniques.
