A written parliamentary answer reveals that 267 patients were removed in the SHA area in 2005/6, compared with 207 in 2004/5, a rise of 29 per cent.
London was second worst with 224, East of England third with 170, Yorkshire and the Humber fourth with 135 and the South West fifth with 92.
The area with the lowest such removals was South Central with 39.
The number of such removals across England rose from 1,101 in 2004/5 to 1,190 in 2005/6, a total of 8.1 per cent.
The figures were compiled by the DoH's Information Centre for Health and Social Care.
Dr Rob Barnett, Liverpool LMC secretary, said: ‘I can't understand why the North West would be different to anywhere else. I'm shocked to hear it's the worst.
‘There are problems with people being aggressive and violent. Attacks and assaults are undoubtedly on the increase.'
A North West SHA spokesman was unavailable for comment.
