To ask the Secretary of State for Health how many admissions to hospital for rheumatoid arthritis there were in each year since 1991-92, broken down by (a) sex, (b) age and (c) primary care trust area. (249254)

Unfortunately we are unable to provide time series data as far back as 1991-92 as the quality of coverage of primary care trust of residence reduces heavily. Data from 1996-97 to 2006-07 have therefore been placed in the Library.
