Record linkage of domestic assault victims between an emergency department and the police.

C ommunity surveys show that domestic violence is a common problem affecting about 5% of the population each year. Around 1% of emergency department visits in the UK are attributable to domestic assault. 3 The British Home Office estimates that 2.9 million domestic assault injuries occur every year in the UK. It is not clear how many domestic assault victims who present to an emergency department also have their assault recorded as a crime by the police. We aimed to identify what proportion of cases presenting at the emergency department had their assault recorded by the police and what the completeness of these lists were.
