Learning collaboration in General Internal Medicine: a pilot project for undergraduate students in nursing, physiotherapy and medicine

Background: A form of education called Interprofessional Education (IPE) occurs when two or more professions learn with, from and about each other. The purpose of IPE is to improve collaboration and the quality of care. Today, IPE is considered as a key educational approach for students in the health professions. IPE is highly effective when delivered in active patient care, such as in clinical placements. General internal medicine (GIM) is a core discipline where hospital-based clinical placements are mandatory for students in many health professions. However, few interprofessional (IP) clinical placements in GIM have been implemented. We designed such a placement. Placement design: The placement took place in the Department of Internal Medicine at the CHUV. It involved students from nursing, physiotherapy and medicine. The students were in their last year before graduation. Students formed teams consisting of one student from each profession. Each team worked in the same unit and had to take care of the same patient. The placement lasted three weeks. It included formal IP sessions, the most important being facilitated discussions or "briefings" (3x/w) during which the students discussed patient care and management. Four teams of students eventually took part in this project. Method: We performed a type of evaluation research called formative evaluation. This aimed at (1) understanding the educational experience and (2) assessing the impact of the placement on student learning. We collected quantitative data with pre-post clerkship questionnaires. We also collected qualitative data with two Focus Groups (FG) discussions at the end of the placement. The FG were audiotaped and transcribed. A thematic analysis was then performed. Results: We focused on the qualitative data, since the quantitative data lacked of statistical power due to the small numbers of students (N = 11). Five themes emerged from the FG analysis: (1) Learning of others' roles, (2) Learning collaborative competences, (3) Striking a balance between acquiring one's own professional competences and interprofessional competences, (4) Barriers to apply learnt IP competences in the future and (5) Advantages and disadvantages of IP briefings. Conclusions: Our IP clinical placement in GIM appeared to help students learn other professionals' roles and collaborative skills. Some challenges (e.g. finding the same patient for each team) were identified and will require adjustments.

Plaisir et souffrance au travail : une lecture psychodynamique au sein d'un office régional de placement suisse

En Suisse, comme dans la plupart des pays industrialisés, le stress au travail et l'épuisement qui en découle sont devenus, au cours des dernières décennies, une réalité qui ne cesse de s'accentuer. Différentes disciplines scientifiques ont tenté de rendre compte, depuis le milieu du siècle dernier, des difficultés rencontrées par les individus dans le cadre de leur travail, avec une prédominance marquée pour des analyses de type causaliste. Dans le cadre de cette étude doctorale, nous nous sommes penché sur le cas d'un office régional de placement, mais avec une perspective sensiblement différente. La grille de lecture psychodynamique utilisée permet en effet de donner accès au sens des situations de travail et d'ouvrir sur une compréhension originale des mécanismes à l'origine des problèmes de santé mentale au travail. Cette approche permet ainsi de comprendre les rapports complexes que les individus entretiennent avec leur travail tel que structuré et organisé, et d'analyser leur expérience en termes de plaisir, de souffrance, de défenses face à la souffrance et de répercussions sur la santé. Dans ce but, nous avons utilisé une méthodologie basée sur des entrevues collectives, afin de stimuler l'expression libre des travailleurs. L'enquête s'est déroulée en deux temps : une première série d'entretiens de groupe a permis la récolte des données empiriques, puis une seconde série, appelée entretiens de restitution, a donné la possibilité aux participants de réagir sur l'interprétation de leur parole faite par le chercheur, et de valider l'analyse. Nos résultats mettent alors en évidence que le travail, tel qu'organisé au sein de cette institution de service public, apparaît considérablement pathogène, mais heureusement compensé par le pouvoir structurant de la relation d'aide aux assurés. Ils montrent également que l'expérience subjective de travail des participants a pour principales sources de souffrance la perception désagréable d'un manque de reconnaissance, d'autonomie et de pouvoir sur leurs actes. - In Switzerland and in other industrialized countries, work-related stress and resulting burn-out has become an ever increasing problem in recent decades. Many researchers Jrom many different fields have made efforts to understand the difficulties employees encounter at work since the middle of the last century. Most of this research is based on a cause and effect analysis approach. For this doctoral research project, we have analyzed cases handled by an unemployment office in Switzerland. We have taken a novel approach by using a number of psychodynamic criteria which permitted us to interpret situations at work and to open up a new way of understanding the mechanisms at work which lead to mental health problems. This approach allows us to understand account the complex relationship people have towards structured and organized work as well as to take into account and to analyze their experience in terms of pleasure, suffering, defense mechanisms against suffering and the consequences on their mental health. In order to achieve this goal we performed collective interviews in order to encourage workers to express themselves freely. The interviews were divided into two series. The first series of group interviews allowed us to collect empirical statistics and the second series gave the workers an opportunity to react to the researchers ' analysis of their answers and to validate the researchers ' interpretation of their answers. Our results show that work has considerable negative effects on mental health. Fortunately, these negative effects are counterbalanced by the psychological support system offered by the unemployment office. Our project also shows that the subjective negative experiences of workers are caused by their perceptions of being under-appreciated, lack of autonomy and having no power over their acts.

Une conséquence d'un état de stress chronique au travail : dossier

Le burn-out ou syndrome d'épuisement professionnel (Z73.0 selon le CIM-10) a été décrit la première fois en 1980 par le psychanalyste Freudenberger puis repris par Maslach et Jackson en 1986. [Auteure]

Functional late outgrowth endothelial progenitors isolated from peripheral blood of burned patients.

BACKGROUND: Bioengineered skin substitutes are increasingly considered as a useful option for the treatment of full thickness burn injury. Their viability following grafting can be enhanced by seeding the skin substitute with late outgrowth endothelial progenitor cells (EPCs). However, it is not known whether autologous EPCs can be obtained from burned patients shortly after injury. METHODS: Late outgrowth EPCs were isolated from peripheral blood sampled obtained from 10 burned patients (extent 19.6±10.3% TBSA) within the first 24h of hospital admission, and from 7 healthy subjects. Late outgrowth EPCs were phenotyped in vitro. RESULTS: In comparison with similar cells obtained from healthy subjects, growing colonies from burned patients yielded a higher percentage of EPC clones (46 versus 17%, p=0.013). Furthermore, EPCs from burned patients secreted more vascular endothelial growth factor (VEGF) into the culture medium than did their counterparts from healthy subjects (85.8±56.2 versus 17.6±14pg/mg protein, p=0.018). When injected to athymic nude mice 6h after unilateral ligation of the femoral artery, EPCs from both groups of subjects greatly accelerated the reperfusion of the ischaemic hindlimb and increased the number of vascular smooth muscle cells. CONCLUSIONS: The present study supports that, in patients with burns of moderate extension, it is feasible to obtain functional autologous late outgrowth EPCs from peripheral blood. These results constitute a strong incentive to pursue approaches based on using autotransplantation of these cells to improve the therapy of full thickness burns.

Entrevista y urgencia social: un reto para las competencias profesionales del educador social

Si decimos que los seres humanos sólo son capaces de vivir como tales mediante la reconstrucción narrativa de sus experiencias, estamos teniendo en cuenta conceptos e ideas que recuerdan a algunos autores contemporáneos (Ricoeur, Gadamer) que defienden la importancia de ser reconocido como una creatura hecha de palabras. En la medida en que son interpretadas, traducidas, contextualizadas y ordenadas por los profesionales, la situación dialogal significativa cobra importancia. Desde esta perspectiva hemos planteado las asignaturas: Habilidades Sociales, Técnicas de Entrevista y Gestión de Situación de Crisis diseñadas para integrar los diferentes modelos teóricos y las variables que se presentan en la relación comunicativa con el usuario y en particular en la situación de entrevista. Se mostrará también el modo cómo en nuestro proceso formativo, basado en la simulación de situaciones, se fomenta el compromiso con el trabajo en equipo, la autocomprensión y enseña a crear un clima de trabajo cooperativo en el que se hace más eficaz la relación de ayuda. A través de la presentación en clase de un caso práctico en el cual se describen todos los procedimientos y las fases del que se compone el ejercicio de la práctica profesional –paso a paso-, se busca poner de manifiesto las competencias adquiridas, los modelos empleados y las habilidades sociales que han sido necesarias para afrontar con éxito la situación de urgencia social. Finalmente se deja abierta la cuestión sobre la manera en que incide y beneficia este aprendizaje en las futuras situaciones de manejo del estrés profesional (burn out).

Development of a cost-effective method for platelet-rich plasma (PRP) preparation for topical wound healing.

Platelet-rich plasma (PRP) is a volume of plasma fraction of autologous blood having platelet concentrations above baseline whole-blood values due to processing and concentration. PRP is used in various surgical fields to enhance soft-tissue and bone healing by delivering supra-physiological concentrations of autologous platelets at the site of tissue damage. These preparations may provide a good cellular source of various growth factors and cytokines, and modulate tissue response to injury. Common clinically available materials for blood preparations combined with a two-step centrifugation protocol at 280g each, to ensure cellular component integrity, provided platelet preparations which were concentrated 2-3 fold over total blood values. Costs were shown to be lower than those of other methods which require specific equipment and high-cost disposables, while safety and traceability can be increased. PRP can be used for the treatment of wounds of all types including burns and also of split-thickness skin graft donor sites, which are frequently used in burn management. The procedure can be standardized and is easy to adapt in clinical settings with minimal infrastructure, thus enabling large numbers of patients to benefit from a form of cellular therapy.

Evaluation of a modified Broström-Gould procedure for treatment of chronic lateral ankle instability: A retrospective study with critical analysis of outcome scoring.

BACKGROUND: Chronic lateral ankle instability accounts for 20% of the ankle injuries. This study evaluates functional outcome of the modified Broström-Gould technique using suture anchors, with 4 different clinical scores. METHODS: A consecutive series of 41 patients were included with a minimum follow-up of one year. The function was assessed using 4 clinical scores including: the AOFAS for hind foot; the FAAM; the CAIT and the CAIS. RESULTS: Out of 41 patients; 27 patients were very satisfied, 11 satisfied and 3 were not satisfied. Ankle mobility returned to normal in 93% of patients. At follow-up the AOFAS was 89/100 (37-100), the FAAM 85/100% (35-100%), the CAIT 20/30 (5-30), and the CAIS 74/100% (27-100%). CONCLUSION: Outcome of modified Broström-Gould procedure is good with high satisfaction rate in terms of ankle mobility. The disparity in outcome of scores, signals towards the need of a standard evaluation system.

Introducing a new MRI classification of lumbar spinal stenosis based on cross-sectional morphology of the dural sac : 37

Introduction: Measures of the degree of lumbar spinal stenosis (LSS) such as antero-posterior diameter of the canal, and dural sac cross sectional area vary, and do not correlate with symptoms or results of surgery. We created a grading system, comprised of seven categories, based on the morphology of the dural sac and its contents as seen on T2 axial images. The categories take into account the ratio of rootlet/ CSF content. Grade A indicates no significant compression, grade D is equivalent to a total myelograhic block. We compared this classification with commonly used criteria of severity of stenosis. Methods: Fifty T2 axial MRI images taken at disc level from 27 symptomatic LSS patients undergoing decompressive surgery were classified twice by two radiologists and three spinal surgeons working at different institutions and countries. Dural sac cross-sectional surface area and AP diameter of the canal were measured both at disc and pedicle level from DICOM images using OsiriX software. Intraand inter-observer reliability were assessed using Cohen's, Fleiss' kappa statistics, and t test. Results: For the morphological grading the average intra-and inter observer kappas were 0.76 and 0.69+, respectively, for physicians working in the study originating country. Combining all observers the kappa values were 0.57 ± 0.19. and 0.44 ± 0.19, respectively. AP diameter and dural sac cross-sectional area measurements showed no statistically significant differences between observers. No correlation between morphological grading and AP diameter or dural sac crosssectional areawas observed in 13 (26%) and 8 cases (16%), respectively. Discussion: The proposed morphological grading relies on the identification of the dural sac and CSF better seen on full MRI series. This was not available to the external observers, which might explain the lower overall kappa values. Since no specific measurement tools are needed the grading suits everyday clinical practice and favours communication of degree of stenosis between practising physicians. The absence of a strict correlation with the dural sac surface suggests that measuring the surface alone might be insufficient in defining LSS as it is essentially a mismatch between the spinal canal and its contents. This grading is now adopted in our unit and further studies concentrating on relation between morphology, clinical symptoms and surgical results are underway.

Teaching motivational interviewing to medical students : a pre-post test pilot study

Objective: To test the efficacy of teaching motivational interviewing (MI) to medical students. Methods: Thirteen 4th year medical students volunteered to participate. Seven days before and 7 days after an 8-hour interactive training MI workshop, each student performed a videorecorded interview with two standardized patients: a 60 year old alcohol dependent woman and a 50 year old cigarette smoking man. Students' counseling skills were coded by two blinded clinicians using the Motivational Interviewing Treatment Integrity 3.0 (MITI). Inter-rater reliability was calculated for all interviews and a test-retest was completed in a sub-sample of 10 consecutive interviews three days apart. Difference between MITI scores before and after training were calculated and tested using non-parametric tests. Effect size was approximated by calculating the probability that posttest scores are greater than pretest scores (P*=P(Pre<Post)+1/2P(Pre=Post)), P*>1/2 indicating greater scores in posttest, P*=1/2 no effect, and P*<1/2 smaller scores in posttest. Results: Median differences between MITI scores before and after MI training indicated a general progression in MI skills: MI spirit global score (median difference=1.5, Inter quartile range=1.5, p<0.001, P*=0.90); Empathy global score (med diff=1, IQR=0.5, p<0.001, P*=0.85); Percentage of MI adherent skills (med diff=36.6, IQR=50.5, p<0.001, P*=0.85); Percentage of open questions (med diff=18.6, IQR=21.6, p<0.001, P*=0.96); reflections/ questions ratio (med diff=0.2, IQR=0.4, p<0.001, P*=0.81). Only Direction global score and the percentage of complex reflections were not significantly improved (med diff=0, IQR=1, p=0.53, P*=0.44, and med diff=4.3, IQR=24.8, p=0.48, P*=0.62, respectively). Inter-rater reliability indicated weighted kappa ranged between 0.14 for Direction to 0.51 for Collaboration and ICC ranged between 0.28 for Simple reflection to 0.95 for Closed question. Test-retests indicated weighted kappa ranged between 0.27 for Direction to 0.80 for Empathy and ICC ranged between 0.87 for Complex reflection to 0.98 for Closed question. Conclusion: This pilot study indicated that an 8-hour training in MI for voluntary 4th year medical students resulted in significant improvement of MI skills. Larger sample of unselected medical students should be studied to generalize the benefit of MI training to medical students. Interrater reliability and test-retests suggested that coders' training should be intensified.

Assessment of a new MRI classification of spinal stenosis based on cross-sectional morphology of the dural sac : FM2

Introduction: Quantitative measures of degree of lumbar spinal stenosis (LSS) such as antero-posterior diameter of the canal or dural sac cross sectional area vary widely and do not correlate with clinical symptoms or results of surgical decompression. In an effort to improve quantification of stenosis we have developed a grading system based on the morphology of the dural sac and its contents as seen on T2 axial images. The grading comprises seven categories ranging form normal to the most severe stenosis and takes into account the ratio of rootlet/CSF content. Material and methods: Fifty T2 axial MRI images taken at disc level from twenty seven symptomatic lumbar spinal stenosis patients who underwent decompressive surgery were classified into seven categories by five observers and reclassified 2 weeks later by the same investigators. Intra- and inter-observer reliability of the classification were assessed using Cohen's and Fleiss' kappa statistics, respectively. Results: Generally, the morphology grading system itself was well adopted by the observers. Its success in application is strongly influenced by the identification of the dural sac. The average intraobserver Cohen's kappa was 0.53 ± 0.2. The inter-observer Fleiss' kappa was 0.38 ± 0.02 in the first rating and 0.3 ± 0.03 in the second rating repeated after two weeks. Discussion: In this attempt, the teaching of the observers was limited to an introduction to the general idea of the morphology grading system and one example MRI image per category. The identification of the dimension of the dural sac may be a difficult issue in absence of complete T1 T2 MRI image series as it was the case here. The similarity of the CSF to possibly present fat on T2 images was the main reason of mismatch in the assignment of the cases to a category. The Fleiss correlation factors of the five observers are fair and the proposed morphology grading system is promising.

Biologicals and fetal cell therapy for wound and scar management.

Few biopharmaceutical preparations developed from biologicals are available for tissue regeneration and scar management. When developing biological treatments with cellular therapy, selection of cell types and establishment of consistent cell banks are crucial steps in whole-cell bioprocessing. Various cell types have been used in treatment of wounds to reduce scar to date including autolog and allogenic skin cells, platelets, placenta, and amniotic extracts. Experience with fetal cells show that they may provide an interesting cell choice due to facility of outscaling and known properties for wound healing without scar. Differential gene profiling has helped to point to potential indicators of repair which include cell adhesion, extracellular matrix, cytokines, growth factors, and development. Safety has been evidenced in Phase I and II clinical fetal cell use for burn and wound treatments with different cell delivery systems. We present herein that fetal cells present technical and therapeutic advantages compared to other cell types for effective cell-based therapy for wound and scar management.

To our knowledge, this is the first case report describing the effective control of an invasive deep-burn wound infection using this combination.

O Papel do Ar e Água Ambientais como Veículos de Transmissão de Infeções Fúngicas no Hospital Agostinho Neto, Cidade da Praia, Cabo Verde

Os fungos são um grupo de microrganismos diversificado com uma grande ubiquidade na natureza, podendo ser encontrados no solo, no ar e na água. Alguns destes microrganismos são considerados como verdadeiros agentes patogénicos para humanos e, embora na grande maioria sejam inofensivos para indivíduos saudáveis, tornam-se patogénicos para indivíduos com fragilidade imunológica. A infeção por estes agentes em ambiente hospitalar tem sido relatada neste últimos anos como a principal causa de morte nos pacientes internados com debilidade imunológica. Neste estudo foi feita a monitorização da presença de fungos no ambiente de algumas unidades mais críticas do Hospital Agostinho Neto na cidade da Praia em Cabo Verde durante o mês de Janeiro de 2012, nomeadamente no Bloco Operatório do hospital, no serviço de internamento Cirúrgico e Queimadura, no serviço de internamento de Neonatologia, no serviço de internamento de Infeciologia, no serviço de Oncologia e no serviço de Hemodiálise. No total foram recolhidas 34 amostras de diferentes locais, detectadas 393ufc/m3 no ar, 685ufc/m3 na água e 2696ufc/m2 nas superfícies e isolados 104 fungos morfologicamente diferentes, sendo sido obtidos 29 a partir do ar, 21 de amostras da água e 54 de superfícies. A análise micológica destas amostras revelou uma forte presença dos géneros como Penicillium sp., Cladosporium sp. e Aspergillus sp. em todas as colheitas. Sabendo que a contaminação do ambiente hospitalar por estes agentes pode ser um fator de risco para infeção nosocomial em pacientes com sistema imunitário muito debilitado, sugerimos no final do trabalho algumas linhas orientadoras para minimizar os fatores de risco e propor trabalhos futuros para correlacionar esses fatores com casos de ocorrência de infeções fúngicas no Hospital Agostinho Neto na cidade da Praia, Cabo Verde.

Forest fires: Evaluation of government intervention measures

The purpose of this paper is to examine the relation between government measures, volunteer participation, climate variables and forest fires. A number of studies have related forest fires to causes of ignition, to fire history in one area, to the type of vegetation and weathercharacteristics or to community institutions, but there is little research on the relation between fire production and government prevention and extinction measures from a policy evaluation perspective.An observational approach is first applied to select forest fires in the north east of Spain. Taking a selection of fires with a certain size, a multiple regression analysis is conducted to find significant relations between policy instruments under the control of the government and the number of hectares burn in each case, controlling at the same time the effect of weather conditions and other context variables. The paper brings evidence on the effects of simultaneity and the relevance of recurring to army soldiers in specific days with extraordinary high simultaneity. The analysis also brings light on the effectiveness of twopreventive policies and of helicopters for extinction tasks.
