RESUMEN
BACKGROUND: In medical residency, performance observations are considered an important strategy to monitor competence development, provide feedback and warrant patient safety. The aim of this study was to gain insight into whether and how supervisor-resident dyads build a working repertoire regarding the use of observations, and how they discuss and align goals and approaches to observation in particular. METHODS: We used a qualitative, social constructivist approach to explore if and how supervisory dyads work towards alignment of goals and preferred approaches to performance observations. We conducted semi-structured interviews with supervisor-resident dyads, performing a template analysis of the data thus obtained. RESULTS: The supervisory dyads did not frequently communicate about the use of observations, except at the start of training and unless they were triggered by internal or external factors. Their working repertoire regarding the use of observations seemed to be primarily driven by patient safety goals and institutional assessment requirements rather than by providing developmental feedback. Although intended as formative, the institutional test was perceived as summative by supervisors and residents, and led to teaching to the test rather than educating for purposes of competence development. CONCLUSIONS: To unlock the full educational potential of performance observations, and to foster the development of an educational alliance, it is essential that supervisory dyads and the training institute communicate clearly about these observations and the role of assessment practices of- and for learning, in order to align their goals and respective approaches.

BACKGROUND: Direct observation of clinical task performance plays a pivotal role in competency-based medical education. Although formal guidelines require supervisors to engage in direct observations, research demonstrates that trainees are infrequently observed. Supervisors may not only experience practical and socio-cultural barriers to direct observations in healthcare settings, they may also question usefulness or have low perceived self-efficacy in performing direct observations. A better understanding of how these multiple factors interact to influence supervisors' intention to perform direct observations may help us to more effectively implement the aforementioned guidelines and increase the frequency of direct observations. METHODS: We conducted an exploratory quantitative study, using the Theory of Planned Behaviour (TPB) as our theoretical framework. In applying the TPB, we transfer a psychological theory to medical education to get insight in the influence of cognitive and emotional processes on intentions to use direct observations in workplace based learning and assessment. We developed an instrument to investigate supervisors intention to perform direct observations. The relationships between the TPB measures of our questionnaire were explored by computing bivariate correlations using Pearson's R tests. Hierarchical regression analysis was performed in order to assess the impact of the respective TPB measures as predictors on the intention to perform direct observations. RESULTS: In our study 82 GP supervisors completed our TPB questionnaire. We found that supervisors had a positive attitude towards direct observations. Our TPB model explained 45% of the variance in supervisors' intentions to perform them. Normative beliefs and past behaviour were significant determinants of this intention. CONCLUSION: Our study suggests that supervisors use their past experiences to form intentions to perform direct observations in a careful, thoughtful manner and, in doing so, also take the preferences of the learner and other stakeholders potentially engaged in direct observations into consideration. These findings have potential implications for research into work-based assessments and the development of training interventions to foster a shared mental model on the use of direct observations.

Workplace-Based Assessment (WBA) plays a pivotal role in present-day competency-based medical curricula. Validity in WBA mainly depends on how stakeholders (e.g. clinical supervisors and learners) use the assessments-rather than on the intrinsic qualities of instruments and methods. Current research on assessment in clinical contexts seems to imply that variable behaviours during performance assessment of both assessors and learners may well reflect their respective beliefs and perspectives towards WBA. We therefore performed a Q methodological study to explore perspectives underlying stakeholders' behaviours in WBA in a postgraduate medical training program. Five different perspectives on performance assessment were extracted: Agency, Mutuality, Objectivity, Adaptivity and Accountability. These perspectives reflect both differences and similarities in stakeholder perceptions and preferences regarding the utility of WBA. In comparing and contrasting the various perspectives, we identified two key areas of disagreement, specifically 'the locus of regulation of learning' (i.e., self-regulated versus externally regulated learning) and 'the extent to which assessment should be standardised' (i.e., tailored versus standardised assessment). Differing perspectives may variously affect stakeholders' acceptance, use-and, consequently, the effectiveness-of assessment programmes. Continuous interaction between all stakeholders is essential to monitor, adapt and improve assessment practices and to stimulate the development of a shared mental model. Better understanding of underlying stakeholder perspectives could be an important step in bridging the gap between psychometric and socio-constructivist approaches in WBA.

CONTEXT: During clerkships, teaching and learning in day-to-day activities occur in many moments of interaction among doctors, patients, peers and other co-workers. How people talk with one another influences their identity, their position and what they are allowed to do. This paper focuses on the opportunities and challenges of such moments of interaction between doctors and students during a clerkship characterised by short supervisory relationships. METHODS: This study was conducted in a 10-week internal medicine clerkship. Nine students and 10 doctors who worked with these nine students participated by regularly describing moments of interaction, using dictaphones. We performed critical discourse analysis of material sourced from a total of 184 audio diary entries and seven student debriefing interviews to reveal how participants discursively shaped the way they could think, speak and conduct themselves. RESULTS: The ways in which doctors and students posed and answered questions represented a recurrent and influential feature in the diaries. This Question and Answer dynamic revealed six discourses of Basic Learning Need, Care and Attention, Power Game, Exchange of Currency, Distance, and Equality and Reciprocity. These discourses and the interplay among them revealed both students' and doctors' frameworks of needs and expectations in a culturally defined power structure. The interplay among the discourses reflected the ways in which doctor-student interactions afforded meaningful contributions to their medical or educational practice such as in the exchange of authentic professional or personal experience. CONCLUSIONS: By purposefully bringing power structures to the surface, we have addressed the complexity of learning and teaching as it occurs in day-to-day moments of interaction in a clerkship with little continuity in supervision. Both doctors and students should be supported to reflect critically on how they contribute to supervisory relationships with reference to, for example, the ways in which they ask or answer questions.

The cumulative and definitive nature of chronic cardiotoxicity of anthracyclines requires a preventive strategy of early diagnosis. The authors undertook a prospective study of the association of echocardiography, mitral Doppler and pulsed Doppler tissue imaging of the left ventricular lateral and posterior walls in the context of this problem in 20 patients without cardiac disease undergoing cancer chemotherapy including anthracyclines. Doppler echocardiography was performed before the first session of chemotherapy and at the end of treatment, 6 +/- 4 months later. After a total cumulative dose of 227 +/- 91 mg/m2 of doxorubicine, there were no changes in left ventricular ejection fraction but a significant decrease in mitral E wave velocity (p = 0.04) and in E/A ratio (p = 0.01), suggesting early changes in left ventricular relaxation. The Doppler tissue examination confirmed the presence of radial and longitudinal abnormalities in myocardial relaxation (decreases in myocardial E wave velocities of the posterior and lateral walls of the left ventricle, p = 0.02 and p = 0.01, respectively). The peak velocity of the myocardial systolic wave (Sm) was significantly decreased in the lateral wall (p = 0.02) and approached statistical significance in the posterior wall (p = 0.07). These results suggest concomitant changes in myocardial systolic and diastolic function with moderate doses of anthracyclines. Therefore, pulsed Doppler tissue examination enables earlier detection of left ventricular cardiotoxicity with anthracyclines than classical echocardiographic parameters.

The authors report the case of a 78 year old woman admitted to hospital for recurrent cerebrovascular accidents, the initial investigation of which was normal. This pacemaker patient had a displacement of the definitive ventricular pacing catheter which was positioned in the left ventricle through a patent foramen ovale. The diagnosis was suspected on clinical and echocardiographic examination and confirmed by transthoracic and transoesophageal echocardiography. In view of the risk of systemic embolism, the pacing catheter was repositioned by an endovascular approach in the right ventricle.

Left ventricular ejection fraction is a major prognostic factor of ischaemic heart disease. In the early phase of myocardial infarction, part of the myocardium may be stunned and responsible for marked segmental wall dysfunction which is potentially reversible. The authors studied the potential of low dose dobutamine echocardiography to predict secondary improvement of left ventricular systolic function in 21 patients with recent inaugural myocardial infarction without primary angioplasty. All patients were treated and the investigation was carried out up to 20 micrograms/Kg/min of dobutamine without unwanted side-effects or myocardial ischaemia. The detection of viability by this method was associated with improved wall motion of the affected segments in 74% of cases, most of which had benefited from myocardial revascularisation at control echocardiography performed 8 weeks later. If 4 or more segments were estimated to be viable initially, the left ventricular ejection fraction improved to a value comparable to that obtained at a dosage of 20 micrograms/Kg/min of dobutamine. On the other hand, there was no secondary improvement in 76% of segments estimated to be non-viable whether or not they had been revascularised. The sensitivity, specificity, positive and negative predictive values of low dose dobutamine echocardiography for prediction of myocardial recovery after recent infarction were respectively 71, 79, 74 and 76%. The results of this investigation show prognostic value and could be an aid to the decision concerning revascularisation of patients not having undergone primary angioplasty.

In the present study, four cases of early postoperative constrictive pericarditis have been described which serve as a basis for recalling the current main echographic features of this disorder: pericardial thickening, abnormal septal movement with inspiratory expansion of the right ventricle, respiratory variations in ventricular filling, characteristic modifications in the supra-hepatic pulmonary venous flow, and pulmonary insufficiency. Some hypotheses have also been presented on the possible etiology of this disease. The necessity of making a precise and rapid diagnosis, which should also be confirmed by catheterization to ensure the appropriateness of therapy, has been emphasized. Pericardectomy can determine the long-term prognosis.
