Towards evidence based emergency medicine: best BETs from the Manchester Royal Infirmary

Abstract

Best evidence topic reports (BETs) summarise the evidence pertaining to particular clinical questions.They are not systematic reviews, but rather contain the best (highest level) evidence that can be practically obtained by busy practising clinicians.The search strategies used to find the best evidence are reported in detail in order to allow clinicians to update searches whenever necessary.The BETs published below were first reported at the Critical Appraisal Journal Club at the Manchester Royal Infirmary 1 or placed on the BestBETs website.Each BET has been constructed in the four stages that have been described elsewhere. 2The BETs shown here together with those published previously and those currently under construction can be seen at http:// www.bestbets.org. 3Six BETs are included in this issue of the journal.c Does nimodipine reduce mortality and secondary ischaemic events after subarachnoid haemorrhage?c Aspiration of breast abscesses c Metoclopramide versus placebo with opioid c Safety of inferior vena cava filters as primary treatment for proximal deep vein thrombosis c Screw tipped needles for intraosseous access c Plaster or collar and cuff after reducing dislocated elbow?
