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 Each BET has been constructed in the four stages that have been described elsewhere.2 The BETs shown here together with those published previously and those currently under construction can be seen at Five topics are covered in this issue of the journal.

  • Nasal diamorphine for acute pain relief in children

  • Does a normal CT scan rule out a subarachnoid haemorrhage?

  • Mydriatics in corneal abrasion

  • Midazolam and emergence phenomena in children undergoing ketamine sedation

In addition two prehospital topics are also covered.
