Article Synopsis
  • - Validated clinical decision rules aimed at reducing unnecessary use of computed tomographic pulmonary angiography (CTPA) in emergency departments (EDs) for suspected pulmonary embolism (PE) were analyzed to observe changes in CTPA usage over time.
  • - A retrospective study across 26 European EDs examined nearly 9,000 CTPAs performed between January 2015 and December 2019, revealing significant increases in CTPA usage and diagnosed PEs, particularly among low-risk patients.
  • - The findings indicated a trend toward more frequent CTPA use and a higher diagnosis rate of PEs despite efforts to limit unnecessary imaging, highlighting the need for ongoing assessment of clinical decision rules in practice.

Across the world, the COVID-19 pandemic has forced people to reconsider their habits in terms of how they work, how they interact with each other, and of their mobility. During lockdowns, mobility was in general significantly reduced. Means of collective transportation were used much less, and people preferred means of individual transport.

The diagnosis of acute myocarditis (AM) is based on a multi-parametric assessment including clinical presentation, ECG, imaging and biomarkers. Fragmented QRS (fQRS) might be an additional diagnostic sign in patients with proven AM. The main objective of this study was to assess the diagnostic yield of fQRS in patients with suspected AM presenting to the emergency department (ED).

The COVID-19 pandemic strongly affected mobility around the world. Public transport was particularly hindered, since people may perceive it as unsafe and decide to avoid it. Moreover, in Switzerland, several restrictions were applied at the beginning of the first pandemic wave (16/03/2020), to reduce the contagion.

Background: There have been reports of procoagulant activity in patients with COVID-19. Whether there is an association between pulmonary embolism (PE) and COVID-19 in the emergency department (ED) is unknown. The aim of this study was to assess whether COVID-19 is associated with PE in ED patients who underwent a computed tomographic pulmonary angiogram (CTPA).
