asked the Secretary of State for Social Services how the number of male patients who have been in mental illness hospitals for five years or more in the Mersey region compares with the national average; what research his Department is undertaking into the reasons for the difference; and if he will make a statement.

The estimated number is 1,255; this gives a rate per 100,000 (male) population of 106 which is higher than the national average rate. Numbers are affected by historical and geographical influences on each regions patterns of care, as well as by discharge policies in hospitals and units.
