Management of isolated calf deep vein thrombosis is an area of significant international debate and variable clinical practice. Both therapeutic anticoagulation and conservative management carry risk. As clinical care of suspected and confirmed venous thromboembolic disease increasingly becomes the remit of emergency medicine, complex decisions are left to practising clinicians at the front door. ⋯ Estimates of haemorrhagic risk are based on robust data from large prospective management studies of venous thromboembolic disease; the risks of untreated calf deep vein thrombosis are based on small cohorts and therefore less exact. Pending further trial evidence, these risks should be discussed with patients openly, in the context of personal preference and shared decision-making. Anticoagulation may maximally benefit those patients with extensive and/or symptomatic disease or those with higher risk for complication (unprovoked, cancer-associated or pregnancy).

To define the association between time taken to present to the emergency department (ED) with symptoms of possible acute coronary syndrome (ACS) and 1-year outcomes. We also determined whether particular patient characteristics are associated with delays in seeking care after symptom onset. ⋯ There is an independent association between time to presentation and 1-year cardiac outcomes following initial chest pain assessment for ED patients with possible cardiac chest pain in the Australian and New Zealand setting. This association occurred irrespective of the eventual diagnosis. Effective public health campaigns and other measures that facilitate early presentation with symptoms for patients with symptoms suggestive of ACS are justified and may improve prognosis.

Revascularisation treatment with thrombolysis must be initiated within 4.5 h following ischaemic stroke symptom onset. Despite its proven benefits, thrombolysis therapy is underused, with patient delay in presenting to hospital with symptoms identified as the leading barrier. This study aimed to examine help-seeking behaviour at stroke onset, in order to understand delays in accessing acute medical care for stroke symptoms. ⋯ This study provides insights into patient response when a stroke occurs, with the presence and action of others highlighted as critical in fast response to stroke symptoms. Knowledge of stroke warning signs and risk factors was low among stroke survivors. Findings highlight the complexity of changing help-seeking behaviour during stroke onset, and provide directions for public education efforts to reduce prehospital delay.

Field referral of emergency ambulance patients by paramedics on a widespread basis is a relatively new aspect of paramedicine. Its implementation involves a significant revision to paramedics' clinical responsibilities and level of interaction with medical specialists. Using grounded theory methodology, this qualitative study uses interviews with paramedics from Ontario, Canada, to explore the framing of risk associated with these referrals in the context of caring for patients with two high-stakes medical conditions: acute stroke and S-T elevation myocardial infarction. The results outline how paramedics have incorporated risk framing into their practice.
