This paper is a report of a study of a randomized, non-blinded clinical
trial including people with diabetes mellitus types 1 and 2. In the intervention group
nurse specialists were the central carers, providing care that conformed to a preset
protocol. Patients were included between 2004 and 2007. Costs, quality of life and
adverse events were measured, cost-effect ratios and incremental cost-effect ratios
were calculated based on health-resource utilization rates, corresponding market
prices and national tariffs from 2007.
