Our colleague Daniel Horner meets P Wells, a legendary figure in derivation of clinical prediction rules and author of the famous Wells scores for VTE. They discuss the difficulties in diagnosing VTE in pregnancy, the potential end of AVKs, and the future for VTE research.

The Wells scores for VTE

Emergency Medicine Journal (EMJ) is an international peer review journal covering pre-hospital and hospital emergency medicine, and critical care. The journal publishes original research, reviews and evidence based articles on resuscitation, major trauma, minor injuries, acute cardiology, acute paediatrics, toxicology, toxinology, disasters, medical imaging, audit, teaching and reflections on clinical practice. The journal is aimed at doctors, nurses, paramedics and ambulance staff.

Should we be bringing preventative medicine into the emergency department, or is it just using up valuable time? Our first paper this month looks at the "Cessation of Smoking Trial in the Emergency Department (COSTED)" trial, which presents the case for opportunistic smoking cessation intervention. Next up is a topical research paper on interpreting CT scans with artificial intelligence, and how machine assessment measures up against experienced physicians. Then there's a trio of troponin papers, discussing high-sensitivity testing. The final paper this time is not a paper but a guideline from the Royal College of Emergency Medicine, setting out best practices for dealing with suspected cannabinoid hyperemesis syndrome.Articles discussed in this episode:Cessation of Smoking Trial in the Emergency Department (COSTED): a multicentre randomised controlled trial.

Interventions for smoking cessation, AI CT scan triaging, and cyclic vomiting : May 2024 Primary Survey

“Social distancing is a privilege,” is the core message underlying the first paper brought by Sarah to this month’s roundup, as it unpacks the stark differences in COVID-19 outcomes across the spectrum of racial and ethnic groups in the United States. A second paper examines the returning rates of COVID patients across a large group of emergency departments in Canada, and the factors at play there. The final topic is one of Rick’s favourites, focusing on troponin testing in ambulances.

Aortic dissection, coroners' court, and age-related outcomes: March 2024 Primary Survey

There's a lot of drugs to be talked about this month, and a heap of randomised control trials to be covered too. Rick and Sarah talk though the combining of nitrous oxide and fentanyl for sedation, the environmental impact of analgesics, the efficacy of acute heart failure treatment with high-dose and low-dose nitrates, and more newly published work from the latest issue of the journal.
