§ Mr. Dobsonasked the Secretary of State for Social Services what statistics exist on the prevalence of kidney disease in each year since 1970.
§ Mrs. CurrieThe available information is set out in the table. The in-patient figures are based on a sample of cases, and those for patients dialysing or transplanted are actual numbers. It is essential to note that there is likely to be some overlap between the two groups. These figures take no account of other people with kidney disease being treated as out-patients or by general practitioners, or as yet undiagnosed.
