Desafios na formação médica: a contribuição da avaliação

O curso de medicina da Faculdade de Medicina de Marília (Famema) adota um currículo integrado, orientado por competência, em que a avaliação do desempenho dos estudantes recai sobre aspectos cognitivos, habilidades e atitudes. Desse modo, o objetivo deste estudo foi analisar as concepções dos professores dessa Instituição a respeito da avaliação. Para tanto, realizou-se a filmagem de 12 Exercícios de Avaliação da Prática Profissional (Eapp). Para a análise dos discursos, utilizou-se o método de interpretação dos sentidos, que se baseia em princípios hermenêutico-dialéticos. Foram identificadas diferentes concepções de avaliação, desde a mais tradicional até a mais crítica e reflexiva. Concluiu-se que o Eapp é um espaço privilegiado para avaliar o desempenho dos estudantes e problematizar a prática avaliativa dos professores.

Percepções de alunos de medicina sobre marketing médico

INTRODUÇÃO: Marketing médico é um assunto controverso, principalmente no que concerne a princípios éticos. Portanto, frente à competição acirrada de mercado, é necessário o preparo profissional. Conhecer a percepção dos alunos de Medicina pode auxiliar na estruturação de alternativas de capacitação. METODOLOGIA: Inicialmente, identificaram-se crenças sobre marketing médico através de grupo focal composto por 12 alunos. Com base nesses dados, dez afirmações para avaliar atitudes foram aplicadas aos alunos de uma Faculdade de Medicina pública brasileira. RESULTADOS: Observou-se falta de clareza sobre o conceito de marketing, preocupação com princípios éticos e necessidade de marketing no mercado competitivo. Na fase de aplicação, foram obtidas 280 respostas de diversos estágios do curso. Apenas 16,8% admitiram contato com o tema. Houve clareza sobre ética em relação ao paciente, influenciada positivamente pela progressão no curso, mas houve divergência na ética entre profissionais. CONCLUSÕES: Marketing médico é uma área pouco compreendida e relegada ao currículo oculto, sendo influenciada por transposições inadequadas de métodos didáticos destinados à comunicação profissional para a população leiga. Novos métodos de ensino, como a educação tutorial, podem ser uma alternativa para lidar com essas situações.

A relação professor-aluno em medicina - um estudo sobre o encontro pedagógico

A formação humanística do aluno de Medicina é um importante objetivo educacional nas escolas médicas. Parte dessa formação se dá por meio de disciplinas da área das Humanidades, mas grande parte ocorre pelo aprendizado no ambiente cultural e nas relações interpessoais dentro da escola médica, em especial a relação professor-aluno. Com o objetivo de estudar a relação professor-aluno em uma escola médica padrão no Estado de São Paulo, desenhou-se este estudo de caso. Por meio de observação etnográfica e entrevistas em profundidade, obtivemos dados que foram analisados pelo método hermenêutico dentro de categorias analíticas construídas com base no referencial teórico da pesquisa e nos achados empíricos referentes aos tipos de relação pedagógica observados nessa escola. Descrevemos e interpretamos três tipos de relação dessa natureza, baseados na onipotência do professor, na construção de vínculo e na desqualificação do aluno. Em cada um deles, um modo predominante de comportamento estaria sendo ensinado de modo informal, aproximando ou afastando o ensino da ética e da competência relacional. Conclui-se que as relações professor-aluno na escola médica precisam ser alvo de estudo e atenção, assim como a clara definição de um padrão ético institucional para todos, para que se possa alcançar o objetivo de uma formação humanística em Medicina.

Professional competences of nurse to work in Intensive Care Units: an integrative review

This study aimed to identify and analyze nurses' competences to work at Intensive Care Units-ICU. An integrative review method was used, and data were collected in LILACS, SciELO and BDENF, from August to October 2010. Ten articles were identified, published in the last 12 years. Data grouping permitted the construction of thematic units related to nurses' competences: nursing care management, high-complexity nursing care delivery, decision making, leadership, communication, continuing/permanent education, human resource management, material resource management. The professional competences identified can support the outline of guidelines to constitute the profile of nursing working in intensive care units and drive/mobilize the improvement of nursing care practices.

Ser mentor em medicina: uma visão arquetípica das motivações e transformações na jornada

A tutoria, na modalidade mentoring, tem sido adotada nas escolas médicas como estratégia para oferecer suporte pessoal e estimular o desenvolvimento profissional do futuro médico. O tutor, com papel de mentor, elemento crucial desta relação arquetípica, é pouco estudado em seu desenvolvimento pessoal. Este estudo buscou compreender as motivações de um grupo de tutores e identificar as possíveis transformações ocorridas ao longo do tempo. A investigação consistiu em um estudo qualitativo em que foram entrevistados 14 tutores de um Programa de Tutoria de uma Faculdade de Medicina. Há, entre os tutores, um desejo de restabelecer a antiga, significativa e próxima relação do mestre com o seu discípulo. Simbolicamente, buscam estar em contato com o seu "aluno interno ferido", e dele cuidar. Nessa jornada, podem - mas não necessariamente isso acontece a todos - transformar e ser transformados pelo outro.

Development of Clinical Decision Support Systems based on Mathematical Models of Physiological Systems

In the last years of research, I focused my studies on different physiological problems. Together with my supervisors, I developed/improved different mathematical models in order to create valid tools useful for a better understanding of important clinical issues. The aim of all this work is to develop tools for learning and understanding cardiac and cerebrovascular physiology as well as pathology, generating research questions and developing clinical decision support systems useful for intensive care unit patients. I. ICP-model Designed for Medical Education We developed a comprehensive cerebral blood flow and intracranial pressure model to simulate and study the complex interactions in cerebrovascular dynamics caused by multiple simultaneous alterations, including normal and abnormal functional states of auto-regulation of the brain. Individual published equations (derived from prior animal and human studies) were implemented into a comprehensive simulation program. Included in the normal physiological modelling was: intracranial pressure, cerebral blood flow, blood pressure, and carbon dioxide (CO2) partial pressure. We also added external and pathological perturbations, such as head up position and intracranial haemorrhage. The model performed clinically realistically given inputs of published traumatized patients, and cases encountered by clinicians. The pulsatile nature of the output graphics was easy for clinicians to interpret. The manoeuvres simulated include changes of basic physiological inputs (e.g. blood pressure, central venous pressure, CO2 tension, head up position, and respiratory effects on vascular pressures) as well as pathological inputs (e.g. acute intracranial bleeding, and obstruction of cerebrospinal outflow). Based on the results, we believe the model would be useful to teach complex relationships of brain haemodynamics and study clinical research questions such as the optimal head-up position, the effects of intracranial haemorrhage on cerebral haemodynamics, as well as the best CO2 concentration to reach the optimal compromise between intracranial pressure and perfusion. We believe this model would be useful for both beginners and advanced learners. It could be used by practicing clinicians to model individual patients (entering the effects of needed clinical manipulations, and then running the model to test for optimal combinations of therapeutic manoeuvres). II. A Heterogeneous Cerebrovascular Mathematical Model Cerebrovascular pathologies are extremely complex, due to the multitude of factors acting simultaneously on cerebral haemodynamics. In this work, the mathematical model of cerebral haemodynamics and intracranial pressure dynamics, described in the point I, is extended to account for heterogeneity in cerebral blood flow. The model includes the Circle of Willis, six regional districts independently regulated by autoregulation and CO2 reactivity, distal cortical anastomoses, venous circulation, the cerebrospinal fluid circulation, and the intracranial pressure-volume relationship. Results agree with data in the literature and highlight the existence of a monotonic relationship between transient hyperemic response and the autoregulation gain. During unilateral internal carotid artery stenosis, local blood flow regulation is progressively lost in the ipsilateral territory with the presence of a steal phenomenon, while the anterior communicating artery plays the major role to redistribute the available blood flow. Conversely, distal collateral circulation plays a major role during unilateral occlusion of the middle cerebral artery. In conclusion, the model is able to reproduce several different pathological conditions characterized by heterogeneity in cerebrovascular haemodynamics and can not only explain generalized results in terms of physiological mechanisms involved, but also, by individualizing parameters, may represent a valuable tool to help with difficult clinical decisions. III. Effect of Cushing Response on Systemic Arterial Pressure. During cerebral hypoxic conditions, the sympathetic system causes an increase in arterial pressure (Cushing response), creating a link between the cerebral and the systemic circulation. This work investigates the complex relationships among cerebrovascular dynamics, intracranial pressure, Cushing response, and short-term systemic regulation, during plateau waves, by means of an original mathematical model. The model incorporates the pulsating heart, the pulmonary circulation and the systemic circulation, with an accurate description of the cerebral circulation and the intracranial pressure dynamics (same model as in the first paragraph). Various regulatory mechanisms are included: cerebral autoregulation, local blood flow control by oxygen (O2) and/or CO2 changes, sympathetic and vagal regulation of cardiovascular parameters by several reflex mechanisms (chemoreceptors, lung-stretch receptors, baroreceptors). The Cushing response has been described assuming a dramatic increase in sympathetic activity to vessels during a fall in brain O2 delivery. With this assumption, the model is able to simulate the cardiovascular effects experimentally observed when intracranial pressure is artificially elevated and maintained at constant level (arterial pressure increase and bradicardia). According to the model, these effects arise from the interaction between the Cushing response and the baroreflex response (secondary to arterial pressure increase). Then, patients with severe head injury have been simulated by reducing intracranial compliance and cerebrospinal fluid reabsorption. With these changes, oscillations with plateau waves developed. In these conditions, model results indicate that the Cushing response may have both positive effects, reducing the duration of the plateau phase via an increase in cerebral perfusion pressure, and negative effects, increasing the intracranial pressure plateau level, with a risk of greater compression of the cerebral vessels. This model may be of value to assist clinicians in finding the balance between clinical benefits of the Cushing response and its shortcomings. IV. Comprehensive Cardiopulmonary Simulation Model for the Analysis of Hypercapnic Respiratory Failure We developed a new comprehensive cardiopulmonary model that takes into account the mutual interactions between the cardiovascular and the respiratory systems along with their short-term regulatory mechanisms. The model includes the heart, systemic and pulmonary circulations, lung mechanics, gas exchange and transport equations, and cardio-ventilatory control. Results show good agreement with published patient data in case of normoxic and hyperoxic hypercapnia simulations. In particular, simulations predict a moderate increase in mean systemic arterial pressure and heart rate, with almost no change in cardiac output, paralleled by a relevant increase in minute ventilation, tidal volume and respiratory rate. The model can represent a valid tool for clinical practice and medical research, providing an alternative way to experience-based clinical decisions. In conclusion, models are not only capable of summarizing current knowledge, but also identifying missing knowledge. In the former case they can serve as training aids for teaching the operation of complex systems, especially if the model can be used to demonstrate the outcome of experiments. In the latter case they generate experiments to be performed to gather the missing data.

La circolarita' delle idee nel pensiero medico bolognese: la Societa' Medica Chirurgica in Epoca Pontificia

La tesi di Dottorato, saldamente ancorata alle Medical Humanities, si è concentrata sul modo in cui la storia della letteratura italiana si intreccia con le altre discipline, per arrivare a configurare quell’ampio panorama di storia delle idee che aiuta a valutare l’evoluzione stessa delle credenze e dei pensieri dell’uomo nel corso del tempo. Essa ha contribuito a portare alla luce l’apporto dato dalla Società Medica Chirurgica di Bologna in Epoca Pontificia alla circolarità del pensiero medico, ricordando con forza che le varie correnti storico-mediche non sono appunto il semplice susseguirsi di teorie più o meno esatte. La tesi rende pienamente visibili non solo la struttura e le dinamiche della comunicazione scientifica, ma documenta attraverso la letteratura (anche quella scientifica) la presenza della medicina e delle sue pratiche all’interno della società, soffermandosi sui meccanismi, sui percorsi che legano i fenomeni tra loro; viene declinato anche il complesso e travagliato processo teso a ridefinire la figura del medico durante l’epoca del dominio pontificio nel suo declino, circondata da diffidenze e ostilità. Il fulcro della tesi è dato dalla dimostrazione inconfutabile che esiste ancora un ruolo per la cultura umanistica nella formazione del medico.

Validity evidence and reliability of a Simulated Patient Feedback Instrument

In the training of healthcare professionals, one of the advantages of communication training with simulated patients (SPs) is the SP's ability to provide direct feedback to students after a simulated clinical encounter. The quality of SP feedback must be monitored, especially because it is well known that feedback can have a profound effect on student performance. Due to the current lack of valid and reliable instruments to assess the quality of SP feedback, our study examined the validity and reliability of one potential instrument, the 'modified Quality of Simulated Patient Feedback Form' (mQSF). Methods Content validity of the mQSF was assessed by inviting experts in the area of simulated clinical encounters to rate the importance of the mQSF items. Moreover, generalizability theory was used to examine the reliability of the mQSF. Our data came from videotapes of clinical encounters between six simulated patients and six students and the ensuing feedback from the SPs to the students. Ten faculty members judged the SP feedback according to the items on the mQSF. Three weeks later, this procedure was repeated with the same faculty members and recordings. Results All but two items of the mQSF received importance ratings of > 2.5 on a four-point rating scale. A generalizability coefficient of 0.77 was established with two judges observing one encounter. Conclusions The findings for content validity and reliability with two judges suggest that the mQSF is a valid and reliable instrument to assess the quality of feedback provided by simulated patients.

Pregnancy and breastfeeding in inflammatory bowel disease

Inflammatory bowel disease (IBD) is frequent in women during their peak reproductive years. Accordingly, a significant number of questions and uncertainties arise from this population regarding the risk of transmission of IBD to the offspring, the impact of the disease and therapies on the fertility, the role of the disease on the course of the pregnancy and the mode of delivery, the impact of the therapy on the pregnancy and fetal development as well as breastfeeding. The safety of medical therapy during pregnancy and lactation is a major concern for both pregnant women and their partners as well as for physicians. As a general rule, it can be stated that the benefit of continuing medical therapy in IBD during pregnancy outweighs the potential risks in the vast majority of instances. This article will review recent developments on this topic consistent with the European Crohn's and Colitis Organization guidelines.

European veterinary public health specialization: post-graduate training and expectations of potential employers

Residents of the European College of Veterinary Public Health (ECVPH) carried out a survey to explore the expectations and needs of potential employers of ECVPH diplomates and to assess the extent to which the ECVPH post-graduate training program meets those requirements. An online questionnaire was sent to 707 individuals working for universities, government organizations, and private companies active in the field of public health in 16 countries. Details on the structure and activities of the participants' organizations, their current knowledge of the ECVPH, and potential interest in employing veterinary public health (VPH) experts or hosting internships were collected. Participants were requested to rate 22 relevant competencies according to their importance for VPH professionals exiting the ECVPH training. A total of 138 completed questionnaires were included in the analysis. While generic skills such as "problem solving" and "broad horizon and inter-/multidisciplinary thinking" were consistently given high grades by all participants, the importance ascribed to more specialized skills was less homogeneous. The current ECVPH training more closely complies with the profile sought in academia, which may partly explain the lower employment rate of residents and diplomates within government and industry sectors. The study revealed a lack of awareness of the ECVPH among public health institutions and demonstrated the need for greater promotion of this veterinary specialization within Europe, both in terms of its training capacity and the professional skill-set of its diplomates. This study provides input for a critical revision of the ECVPH curriculum and the design of post-graduate training programs in VPH.
