Assessing clinical reasoning: a method to monitor its development in a PBL curriculum

The aim of this study was to develop and trial a method to monitor the evolution of clinical reasoning in a PBL curriculum that is suitable for use in a large medical school. Termed Clinical Reasoning Problems (CRPs), it is based on the notion that clinical reasoning is dependent on the identification and correct interpretation of certain critical clinical features. Each problem consists of a clinical scenario comprising presentation, history and physical examination. Based on this information, subjects are asked to nominate the two most likely diagnoses and to list the clinical features that they considered in formulating their diagnoses, indicating whether these features supported or opposed the nominated diagnoses. Students at different levels of medical training completed a set of 10 CRPs as well as the Diagnostic Thinking Inventory, a self-reporting questionnaire designed to assess reasoning style. Responses were scored against those of a reference group of general practitioners. Results indicate that the CRPs are an easily administered, reliable and valid assessment of clinical reasoning, able to successfully monitor its development throughout medical training. Consequently, they can be employed to assess clinical reasoning skill in individual students and to evaluate the success of undergraduate medical schools in providing effective tuition in clinical reasoning.

Young women in conflict: Filipinas growing up in Australia

This paper discusses the tensions of adaptation as experienced by 72 young women, born in the Philippines or to immigrant mothers and resident in southeast, far west and far north Queensland, Australia. As illustrated, these women, aged 14-25 years, often have difficulty balancing their expectations with those of their families and of the society in which they live. Like most young Australians they experience some conflicts with parents, but the intersections of race, gender and culture may make it particularly difficult for young Filipinas to develop a sense of their own identity and place in society. The retention of Filipino values often isolates young women from their peers and excludes them from participating in activities considered an important part of growing up Australian, but the adoption of 'Australian' behaviors such as drinking and smoking is not necessarily accompanied by an enhanced sense of belonging.

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.

Telehealth responses to bio-terrorism and emerging infections

Emerging infectious diseases, such as severe acute respiratory syndrome (SARS), are of huge economic importance. They are difficult to predict. The World Health Organization has a Global Outbreak Alert and Response Network, which was involved at an early stage in the SARS outbreak in 2003. Three major lessons were learned as a result of the SARS epidemic in 2003, involving communication, evidence-based action and global partnerships. It is proposed that a series of broadband global response networks should be developed. At a technical level the networks are essentially in place, such as the Internet2 global network. Suitable peripheral devices also exist. What has not yet been created is the appropriate software to allow the use of these networks, although a number of commercial products are in the process of development.

Pessoas em situação de rua e seus cães : fragmentos de união em histórias de fragmentação

O interesse pelo relacionamento entre humanos e cães tem sido crescentemente refletido em produções científicas, apesar destas ainda se mostrarem incipientes no contexto latino-americano, e, por conseguinte, no brasileiro. Nestes termos, quando se toma como foco o relacionamento específico entre cães e pessoas em situação de rua, a incipiência se mostra ainda mais notória, apesar de se tratar de fenômeno que abarca questões interessantes, tanto de cunho individual quanto social e de políticas públicas. Diante disto, a realização do presente estudo se justificou por contribuir com a elucidação da temática, haja vista que teve por objetivo geral: investigar, apontar e compreender relacionamentos estabelecidos por pares que se caracterizem por pertencerem às espécies em questão e por fazerem das ruas espaços para estabelecimento de suas rotinas. Sendo estes critérios de seleção de participantes somados a idade mínima de 18 anos, foram entrevistadas 12 pessoas que nas ocasiões se encontravam em logradouros públicos dos municípios de Vitória, Serra e Vila Velha. Para guiar as entrevistas, foi utilizado roteiro semiestruturado com o intuito de coletar: dados sociais e econômicos dos participantes; conhecer aspectos dos relacionamentos interpessoais dos participantes; acessar relatos que dissessem respeito a partes das histórias de vida de moradores de rua que envolvessem relacionamento com cães; e por fim, recolher informações acerca do uso de serviços de assistência à população de rua, seja na presença ou na ausência do(s) cão(es). Em adição, foram utilizados dados provenientes de conversa informal e voluntária entre a pesquisadora e três funcionárias do Serviço Especializado em Abordagem Social do município de Vitória. A partir daí, os dados coletados foram organizados em cinco grandes itens, nos quais foram detalhadamente analisados e discutidos. Estes itens são: Caracterização sociodemográfica e econômica dos participantes; Caracterização geral dos relacionamentos; Concepções dos participantes acerca dos cães em suas vidas; Repercussões individuais e sociais do relacionamento; e “Sobre pessoas em situação de rua e cães: o "último vínculo"?”. Diante da análise destes, então, tornou-se possível inferir que o relacionamento entre humanos e cães, apesar de manter semelhanças que, por vezes, fazem com que sejam comparados ou equiparados a amizades ou a relacionamentos familiares, se trata de um tipo a parte. Além disto, quando o humano do par homem-cão se encontra em situação de rua, algumas peculiaridades se fazem bastante evidentes, dentre as quais a dificuldade de afastamento do animal, quando em situações momentâneas (por exemplo, em ocasiões de deslocamentos pelas cidades) ou duradouras (como quando por motivos de idas a instituições de abrigamento), em que não é possível tê-lo junto. Por fim, aponta-se como ponderável a recorrente colocação de que o cão seria o único e/ou último vínculo da pessoa em situação de rua com que convive, já que não raramente os participantes mencionaram rearranjos relacionais com humanos posteriores ao início da situação em questão.
