ReviewReview article: Antiemetics in the pre-hospital setting: A systematic review of efficacy and safety.
Antiemetics are medications that are frequently used in the pre-hospital setting. However, recent evidence indicates that antiemetics are ineffective in reducing undifferentiated nausea scores and vomiting rates. The aim of this study is to evaluate the efficacy and safety of antiemetics administered in the pre-hospital setting. ⋯ Further rigorous studies, preferably randomised and double blinded control trials are required to establish the efficacy of antiemetics in the pre-hospital setting. Consequently, antiemetics should be used more selectively and reserved for severe nausea and intractable vomiting in the pre-hospital setting. PROSPERO registration number: CRD42016044090.

Multicenter Study Comparative StudyEffect of a clinical flowchart incorporating Wells score, PERC rule and age-adjusted D-dimer on pulmonary embolism diagnosis, scan rates and diagnostic yield.
To assess the association between the use of a flowchart incorporating Wells score, PERC rule and age-adjusted D-dimer and subsequent imaging and yield rates of computed tomography pulmonary angiogram and nuclear medicine ventilation perfusion scans being ordered in the ED for the assessment of pulmonary embolism. ⋯ The introduction of a clinical flowchart incorporating Wells score, PERC rule and age-adjusted D-dimer was associated with an increase in ED computed tomography pulmonary angiogram and nuclear medicine ventilation perfusion yield rate from 9.9% to 16.5% across the three enrolment hospitals when investigating possible pulmonary embolism. This corresponded to a 40% relative reduction in pulmonary embolism imaging. Diagnosis rates remained unchanged and no cases of missed pulmonary embolism attributable to the flowchart were identified.

ReviewReview article: Do inferior vena cava filters prevent pulmonary embolism in critically ill trauma patients and does the benefit outweigh the risk of insertion? A narrative review article.
Venous thromboembolic disease (VTE) increases the risk of mortality in trauma patients. To decrease the occurrence of VTE, low dose anticoagulants are commonly prescribed. This may be unacceptable in trauma patients who have a high risk of bleeding. ⋯ The clinical question posed was does prophylactic IVC filter insertion decrease the risk of PE in trauma patients? The available evidence was low level and unable to definitively answer this question. The majority of articles infer that IVC filter insertion is safe and may decrease the risk of PE. However, there is a need for well-designed randomised controlled trials to be conducted in this area.
