A short-cut review was carried out to determine whether the International Normalised Ratio (INR) value was a predictor of the risk of intracranial haemorrhage in patients taking warfarin after head injury. 796 papers were found using the reported search, of which eighteen were directly relevant. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses are shown in the accompanying table. It is concluded that level of the INR correlates poorly with the risk of haemorrhage and that the risk of haemorrhage remains significant even in patients with a sub-therapeutic INR.

Review
BET 2: The use of bedside ultrasound in diagnosing retinal detachment in emergency department.
A short-cut review was carried out to determine whether retinal detachment can be reliably diagnosed by an Emergency Department ocular ultrasound scan. Fifty eight papers were identified using the reported search, of which, eight were considered relevant to the three-part question. It is concluded by the limited evidence available that Emergency Department ocular ultrasound has promise as a sensitive test for retinal detachment.

The aim of this study was to derive and internally validate a prediction rule for short stay admissions (SSAs) in trauma patients admitted to a major trauma centre. ⋯ We report a prediction rule that could be used to establish admission criteria for a trauma short stay unit. Further studies are required to prospectively validate the prediction rule.

Controlled Clinical Trial Observational Study
Is air transport of stroke patients faster than ground transport? A prospective controlled observational study.
Helicopters are widely used for interhospital transfers of stroke patients, but the benefit is sparsely documented. We hypothesised that helicopter transport would reduce system delay to thrombolytic treatment at the regional stroke centre. ⋯ We found significantly shorter time from contact to triaging neurologist to arrival in the regional stroke centre if stroke patients were transported by primarily dispatched ground ambulance compared with a secondarily dispatched helicopter.
