PCDDs in the water/sediment-seagrass-dugong (Dugong dugon) food chain on the Great Barrier Reef (Australia)

Polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) concentrations were measured in sediment and seagrass from five locations in or adjacent to the Great Barrier Reef Marine Park. A full spectrum of Cl(5-8)DDs were present in all samples and, in particular, elevated levels of Cl8DD were found. PCDFs could not be quantified in any samples. The PCDD concentrations ranged over two orders of magnitude between sites, and there was a good correlation between sediment and seagrass levels. There were large quantities of sediment present on the seagrass (20-62% on a dry wt. basis), and it was concluded that this was a primary source of the PCDDs in the seagrass samples. The PCDD levels in the seagrass samples were compared with the levels in the tissue of three dugongs stranded in the same region. The relative accumulation of the 2,3,7,8-substituted PCDD congeners in the dugongs decreased by over two orders of magnitude with increasing degree of chlorination. This was attributed to the reduced absorption of the higher chlorinated congeners in the digestive tract, a behaviour that has been observed in other mammals such as domestic cows.

Food safety and development of the beef industry in China

Food safety concerns have escalated in China as they have elsewhere, especially in relation to meats. Beef production and consumption has increased proportionately faster than all other meats over the last two decades. Yet the slaughtering, processing and marketing of beef remains, for the most part, extremely primitive when compared with Western beef supply chains. By comparing the economics of household slaughtering with that of various types of abattoirs, this paper explains why household slaughtering and wet markets still dominate beef processing and distribution in China. The negative economic, social and industry development implications of enforcing more stringent food safety regulations are highlighted. The willingness/capacity of consumers to pay the added cost of better inspection and other services to guarantee food safety is investigated. In this context, the paper also evaluates the market opportunities for both domestic and imported Green Beef. The paper questions the merit of policy initiatives aimed at modernising Chinese beef supply chains for the mass market along Western lines. (C) 2002 Elsevier Science Ltd. All rights reserved.

Cost comparison of hospital- and home-based treatment models for acute chronic obstructive pulmonary disease

This trial compared the cost of an integrated home-based care model with traditional inpatient care for acute chronic obstructive pulmonary disease (COPD). 25 patients with acute COPD were randomised to either home or hospital management following request for hospital admission. The acute care at home group costs per separation ($745, CI95% $595-$895, n = 13) were significantly lower (p < 0.01) than the hospital group ($2543, CI95% $1766-$3321, n = 12). There was an improvement in lung function in the hospital-managed group at the Outpatient Department review, decreased anxiety in the Emergency Department in the home-managed group and equal patient satisfaction with care delivery. Acute care at home schemes can substitute for usual hospital care for some patients without adverse effects, and potentially release resources. A funding model that allows adequate resource delivery to the community will be needed if there is a move to devolve acute care to community providers.

Surgical programme at Royal Alexandra Hospital, Sydney, for Papua New Guinea children with congenital heart disease, 1978-1994

Objective : To report the history of the Royal Alexandra Hospital for Children (RAHC) Papua New Guinea (PNG) cardiac surgical programme and describe the selection, preoperative clinical features and postoperative outcome of children with congenital heart disease managed by the programme. Methods : Details for each of the PNG cardiac patients admitted to RAHC following selection by visiting cardiologists between 1978 and 1994 were entered into a database, and analysed and interpreted. Results : A congenital heart defect was confirmed in 165 of the 170 children selected. The male to female ratio was 1:1 and the mean age on admission to RAHC was 5.5 years. Almost all of the children for whom data were available (98%) had a weight for age and 41% had a height for age less than the 3rd centile. One-sixth had delayed milestones. A large number were tachypnoeic, in heart failure, or had pulmonary hypertension on admission. Ventricular septal defect and tetralogy of Fallot were the commonest defects, and lesions such as aortic stenosis, coarctation of the aorta and transposition of the great arteries were absent or rare. Thirty-one (19%) of the children selected initially did not receive surgery because of pulmonary hypertension, or because the lesions did not fall within the programme guidelines for operation. One hundred and twenty-nine children had corrective and four had palliative procedures. Half of the operated children had postoperative complications. Eight children died, all following open-heart procedures, giving a case fatality rate of 6%. Preoperative tachypnoea, hepatomegaly, cardiac failure and pulmonary hypertension were strongly associated with poor outcome. Conclusions : The programme was an arduous exercise for all organizations concerned, but achieved comparatively good short-term outcomes. The experience gained should assist in planning for similar programmes.

Acessibilidade e longitudinalidade no pré-natal : análise de um grupo de puérperas atendidas no Hospital Universitário Cassiano Antônio de Moraes

A atenção primária visa garantir cobertura e acesso a cuidados de saúde abrangentes e aceitáveis pela população enfatizando a prevenção e a educação (STARFIELD, 2004). No Brasil a Estratégia Saúde da Família (ESF) é o modelo implantado pelo Ministério da Saúde (MS) com a finalidade de reestruturação da atenção primária e já abrange cerca de 50% da população. Segundo Starfield (2004) a atenção primária pode ser avaliada através de seus atributos essenciais: atenção de primeiro contato (utilização e acessibilidade), longitudinalidade, integralidade e coordenação de cuidados. No contexto da atenção à saúde brasileira, a mortalidade infantil é fato preocupante, principalmente a mortalidade que ocorre nos primeiros dias de vida. Este componente da mortalidade é intimamente relacionado à qualidade da atenção recebida no período gestacional. A atenção pré-natal deve incluir ações organizadas, amplas, integradas e com cobertura abrangente de promoção e prevenção da saúde, além de diagnóstico e tratamento adequado dos problemas que possam vir a ocorrer nesse período. O objetivo do presente estudo foi analisar o pré-natal de um grupo de puérperas quanto aos atributos da atenção primária acessibilidade e longitudinalidade. Para alcançar este objetivo foram realizadas 80 entrevistas com mulheres que realizaram pré-natal na atenção primária e 19 mulheres que realizaram pré-natal no Hospital Universitário Cassiano Antônio de Moraes (HUCAM). Utilizou-se parcialmente o questionário de avaliação da atenção primária PCATool. As puérperas também foram questionadas quanto à percepção da adequação do pré-natal realizado. A acessibilidade foi baixa para a maioria das entrevistadas. Nas puérperas que realizaram o pré-natal na Atenção primária a acessibilidade foi estatisticamente maior naquelas que realizaram pré-natal na ESF e naquelas que utilizaram as unidades de saúde do município de Vitória (ES). A longitudinalidade se relacionou ao tipo de unidade de saúde do pré-natal, ao número de consultas realizadas e ao índice de Ápgar no primeiro minuto. A percepção de um pré-natal adequado se relacionou com a utilização da ESF como serviço de pré-natal e à realização de seis ou mais consultas. Apesar de as puérperas do grupo que realizou o pré-natal no HUCAM perceberem o atendimento pré-natal como adequado, algumas questões revelaram fragilidades na assistência, principalmente quanto ao acesso ao serviço. A impossibilidade de receber atendimento pela equipe fora dos horários de funcionamento do ambulatório, a falta de um número de telefone no qual possam sanar dúvidas ou falar com o médico responsável pelo pré-natal, a percepção de dificuldade na marcação de consultas e a espera prolongada no dia do atendimento são pontos que devem ser melhorados nessa assistência.

Analysis of the return on preventive measures in musculoskeletal disorders through the benefitecost ratio: A case study in a hospital

Work-related musculoskeletal disorders (WMSDs) are among the most costly health problems that society is facing today. Prevention involves investments and it is important for organizations to make a cost ebenefit analysis of ergonomic projects. Return on prevention is a recent concern in the domain of occupational safety and health (OSH). There are many studies concerning the return on the prevention of WMSDs, in terms of the benefits for the organization in which the preventive measures are implemented. However, it is also important to perform an analysis of the impact of each measure on society (externalities). A model to perform a financial and economic costebenefit analysis related to OSH projects was developed and it was applied in the case of the prevention of WMSDs in a Portuguese hospital. An analysis of the accidents and corresponding costs has been made in six of the services of the hospital. Financial and an economic costebenefit analysis have been made and the benefitecost ratio (B/C) has been calculated. While the B/C financial ratio, considering only the benefits to the hospital, is around 2, the economic B/C ratio, taking into account all the external benefits that have been quantified, is higher than 14. Relevance to industry: Both the economic and the financial B/C ratio are important support tools for decision makers in public and private organizations, helping them to define which preventive measures should be implemented, taking into account the costs involved and the resulting quantified benefits, for the organization, for the workers and for the society.

Comparison of fungal contamination between hospitals and companies food units

A descriptive study was developed to compare air and surfaces fungal contamination in ten hospitals’ food units and two food units from companies. Fifty air samples of 250 litres through impaction method were collected from hospitals’ food units and 41 swab samples from surfaces were also collected, using a 10 by 10 cm square stencil. Regarding the two companies, ten air samples and eight surface samples were collected. Air and surface samples were collected in food storage facilities, kitchen, food plating and canteen. Outdoor air was also collected since this is the place regarded as a reference. Simultaneously, temperature, relative humidity and meal numbers were registered. Concerning air from hospitals’ food units, 32 fungal species were identified, being the two most commonly isolated genera Penicillium sp.

Marketing e imagem: o caso do Hospital de Santa Maria - Porto

O sector da saúde ocupa, actualmente, um espaço muito visível na nossa sociedade, quer seja em termos económicos como sociais. Os utentes têm alterado as suas atitudes, tendo vindo a preocupar-se e a exigir cada vez mais dos serviços de saúde. Estas mudanças têm conduzido as Organizações a desenvolver serviços mais orientados para o marketing. Desta forma, reconhece-se a importância dessa avaliação como forma de aumentar os níveis de satisfação dos utentes e da eficiência organizacional. A estratégia de Marketing, passa pela escolha dos mercados alvo, da sua posição competitiva face aos seus concorrentes, que permita atender os seus utentes. Neste contexto, o Marketing poderá desempenhar um papel preponderante na rentabilidade e competitividade das Organizações, pelo que se achou pertinente desenvolver as estratégias de Marketing numa Instituição Privada de Saúde. Assim, no âmbito do 2º. Ano de Mestrado de Gestão das Organizações, ramo Unidades de Saúde, foi realizado um estágio na área do Marketing e Imagem, que teve lugar no Hospital de Santa Maria – Porto. Assim, com este relatório pretende-se reflectir sobre as actividades desenvolvidas, desde a conceptualização à realização das mesmas, e o seu impacto na Organização e, simultaneamente, disponibilizar um instrumento de avaliação da Unidade Curricular.

Controlo da qualidade dosimétrico no serviço de radioterapia do Hospital CUF Descobertas (HCD): importância do controlo da qualidade do sector da física e resultados da auditoria ESTRO-EQUAL

A calibração e o controlo da qualidade de um acelerador linear são passos muito importantes num serviço de Radioterapia, para garantir a qualidade dos tratamentos prestados. O sector da Física da Unidade de Radioterapia do Hospital Cuf Descobertas implementou um rigoroso Programa de controlo de qualidade ao equipamento produtor de radiação e aos equipamentos medidores de radiação, de acordo com o Dec-Lei 180/2002 e com os protocolos internacionais. Para tal, foram implementados procedimentos, criadas folhas de cálculo, instruções de trabalho e impressos. Foram ainda implementados testes aos equipamentos com periodicidade definida: controlo de qualidade diário e controlo de qualidade após intervenções (manutenções preventivas e correctivas). No decorrer do ano de 2005, o sector da Física colaborou activamente com toda a equipa da Radioterapia na implementação da Norma ISO 9001:2000 no serviço, contribuindo com o seu know how na implementação desta, numa área tão importante como a da garantia da qualidade dos feixes de radiação e das respectivas calibrações em dose. Numa procura de melhoria contínua da qualidade dos serviços prestados aos pacientes, decorre ainda uma auditoria externa da EQUAL-ESTRO*, intercomparação postal com dosímetros termoluminescentes. A qualidade dos feixes de energias utilizados diariamente é analisada, tanto ao nível das calibrações absolutas de cada um dos feixes de fotões e de electrões, como ao nível dos cálculos de dose obtidos com o sistema de planimetria XiO da CMS. Os resultados das duas primeiras fases da intercomparação, relativa aos dois feixes de fotões de 6 MV e 15 MV e feixes de electrões de 4 MeV, 8 MeV e 12 MeV, foram considerados pela EQUAL-ESTRO num nível óptimo (desvio máximo na dose medida em relação à dose de referência |d| ≤ 3%).

Neonatal mortality: description and effect of hospital of birth after risk adjustment

OBJECTIVE: To assess the effect of hospital of birth on neonatal mortality. METHODS: A birth cohort study was carried out in Pelotas, Southern Brazil, in 2004. All hospital births were assessed by daily visits to all maternity hospitals and 4558 deliveries were included in the study. Mothers were interviewed regarding potential risk factors. Deaths were monitored through regular visits to hospitals, cemeteries and register offices. Two independent pediatricians established the underlying cause of death based on information obtained from medical records and home visits to parents. Logistic regression was used to estimate the effect of hospital of birth, controlling for confounders related to maternal and newborn characteristics, according to a conceptual model. RESULTS: Neonatal mortality rate was 12.7‰ and it was highly influenced by birthweight, gestational age, and socioeconomic variables. Immaturity was responsible for 65% of neonatal deaths, followed by congenital anomalies, infections and intrapartum asphyxia. Adjusting for maternal characteristics, a three-fold increase in neonatal mortality was seen between similar complexity hospitals. The effect of hospital remained, though lower, after controlling for newborn characteristics. CONCLUSIONS: Neonatal mortality was high, mainly related to immaturity, and varied significantly across maternity hospitals. Further investigations comparing delivery care practices across hospitals are needed to better understand NMR variation and to develop strategies for neonatal mortality reduction.

Direct medical costs associated with schizophrenia relapses in health care services in the city of São Paulo

OBJECTIVE: To assess direct medical costs associated with schizophrenia relapses in mental health services. METHODS: The study was conducted in three health facilities in the city of São Paulo: a public state hospital; a Brazilian National Health System (SUS)-contracted hospital; and a community mental health center. Medical records of 90 patients with schizophrenia who received care in 2006 were reviewed. Information on inpatient expenditures was collected and used for cost estimates. RESULTS: Mean direct medical cost of schizophrenia relapses per patient was US$ 4,083.50 (R$ 8,167.58) in the public state hospital; US$ 2,302.76 (R$ 4,605.46) in the community mental health center; and US$ 1,198.50 (R$ 2,397.74) in the SUS-affiliated hospital. The main component was daily inpatient room rates (87% - 98%). Medication costs varied depending on the use of typical or atypical antipsychotic drugs. Atypical antipsychotic drugs were more often used in the community mental health center. CONCLUSIONS: Costs associated with schizophrenia relapses support investments in antipsychotic drugs and strategies to reduce disease relapse and the need for mental health inpatient services. Treating patients in a community mental health center was associated with medium costs and added the benefit of not depriving these patients from family life.

Devolução de doses unitárias: análise de uma prática diária

A Distribuição Individual Diária em Dose Unitária deve assegurar o maior rigor no Processo de Distribuição de Medicamentos, o que nem sempre se verificou no Hospital Pedro Hispano, dado que as Doses Unitárias devolvidas pelos Serviços de Internamento, nem sempre seguiam os Parâmetros de Qualidade. Assim, desenvolveu-se um estudo quasi-experimental, longitudinal, prospetivo e analítico, entre 1 de Março a 30 de Junho de 2012, no qual se analisaram as Doses Unitárias, devolvidas pelos Serviços de Internamento da Unidade Local de Saúde de Matosinhos a funcionam com Distribuição Individual Diária em Dose Unitária, tendo-se recolhido as não conformes relativamente aos Parâmetros de Qualidade instituídos. Na 1.ª fase do estudo (Recolha de amostras), foram contabilizadas 337 amostras, correspondentes a uma perda de 471 €. Na 2.ª fase do estudo (Implementação de acções correctivas às amostras previamente recolhidas), foram rejeitadas definitivamente 129 amostras, correspondentes a uma perda de 198 €. Na 4.ª fase do estudo (Segunda recolha de amostras), foram contabilizadas 228 amostras, correspondentes a uma perda de 199 €. A 3.ª fase do estudo incluiu a divulgação dos resultados às enfermeiras chefes dos serviços envolvidos no estudo e a 5.ª fase a comparação dos resultados obtidos na 1.ª, 2.ª e 4.ª fase do estudo. As amostras foram recolhidas em 16 serviços de internamento, sendo os valores monetários mais relevantes associados ao Espessante para alimentos líquidos e ao Imipeno + Cilastatina. A prática observada e sujeita a estudo aumenta os riscos associados ao consumo do medicamento e os custos relativos ao Processo, sendo de eliminar. A sua monitorização deve constituir uma rotina, uma vez que houve mudança de comportamentos. A redução/eliminação desta prática não conforme conduz à integração de novas tarefas com valor acrescentado, com aumento da fiabilidade do Processo.
