Overdiagnosis is the diagnosis of an abnormality that is not associated with a substantial health hazard and that patients have no benefit to be aware of. It is neither a misdiagnosis (diagnostic error), nor a false positive result (positive test in the absence of a real abnormality). It mainly results from screening, use of increasingly sensitive diagnostic tests, incidental findings on routine examinations, and widening diagnostic criteria to define a condition requiring an intervention. ⋯ Overdiagnosis also diverts healthcare professionals from caring about other health issues. Preventing overdiagnosis requires increasing awareness of healthcare professionals and patients about its occurrence, the avoidance of unnecessary and untargeted diagnostic tests, and the avoidance of screening without demonstrated benefits. Furthermore, accounting systematically for the harms and benefits of screening and diagnostic tests and determining risk factor thresholds based on the expected absolute risk reduction would also help prevent overdiagnosis.

Adherence to transfusion guidelines: are we prepared for the Smarter Medicine or Choosing Wisely initiative?
To determine, whether a restrictive transfusion strategy is followed in our hospital and to identify differences in activities within departments and patient groups. ⋯ All wards in our analysis are following the current guidelines based on restrictive transfusion strategies. At the same time, we were able to detect significant differences between different departments and patient characteristics.

Trends and characteristics of attendance at the emergency department of a Swiss university hospital: 2002-2012.
The numbers of people attending emergency departments (EDs) at hospitals are increasing. We aimed to analyse trends in ED attendance at a Swiss university hospital between 2002 and 2012, focussing on age-related differences and hospital admission criteria. ⋯ ED attendance of patients≥65 years increased in absolute and relative terms. The study findings suggest that staff of this ED may want to assess the needs of patients≥65 years and, if necessary, adjust the services (e.g., adapted triage scales, adapted geriatric screenings, and adapted hospital admission criteria).

Building legitimacy by criticising the pharmaceutical industry: a qualitative study among prescribers and local opinion leaders.
The literature has described opinion leaders not only as marketing tools of the pharmaceutical industry, but also as educators promoting good clinical practice. This qualitative study addresses the distinction between the opinion-leader-as-marketing-tool and the opinion-leader-as-educator, as it is revealed in the discourses of physicians and experts, focusing on the prescription of antidepressants. We explore the relational dynamic between physicians, opinion leaders and the pharmaceutical industry in an area of French-speaking Switzerland. ⋯ Local experts were vocal critics of the industry, which nevertheless sponsor their continuing education. This critical attitude enhanced their credibility in the eyes of the prescribing physicians. We discuss how the experts, despite their critical attitude, might still be beneficial to the industry's interests.

Elevation of the mean pulmonary arterial pressure to ≥25 mm Hg within the low-pressure system of the pulmonary circulation is defined as pulmonary hypertension. Pulmonary hypertension may be the consequence of various clinical and pathophysiological entities. ⋯ Remodelling is arguably the most important factor: its complex pathogenesis is not completely understood and no specific treatment directly targets vascular remodelling. This article aims to review the current understanding of the pathogenesis of pulmonary hypertension and to give insights in future developments in this evolving field.
