Sorry to bump an old thread, but after a FOI from my hospital,
Patients with Type 1 = 1384
Patients of type 1 with MDI = 1174
Patients of type 1 with pumps = 59
Some 4.3% of type 1s with pumps.
They also gave me cost information.
Cost per pump = £2500 for a 5yr life span - for the 59 = £147,500
Cost of consumables per year = £1500 per patient = £88,500
They declined to give me costings for MDI patients, referring me to the health board instead, and they are declining the request.
