Services and cost of hospitalization for children and adolescents with insulin-dependent diabetes mellitus in New South Wales.

Data on services for Australian children and adolescents with diabetes are limited. The purpose of the present study was to examine the availability, utilization and some of the costs of services for persons of less than 20 years of age with insulin-dependent diabetes mellitus in New South Wales, and to make recommendations for future services. The numbers of prevalent and incident cases of insulin-dependent diabetes mellitus in the zero- to 19-years' age-group in each of the health regions of the State were estimated using data from the insulin-dependent diabetes mellitus register of the Southern Metropolitan Health Region. Information on the available services for young persons with diabetes was obtained from doctors and diabetes educators around the State, and on the utilization of services in the Southern Metropolitan Health Region from interviewing the families of persons whose names are listed in the diabetes register. An estimated range of the annual direct cost of hospital admissions for diabetes in the zero- to 19-years' age-group in New South Wales was calculated by use of the data collected from the diabetes register, the hospital separation data from the NSW Department of Health, the NSW Department of Health estimated bed-day cost and the estimated average cost of a bed day for diabetic patients at The Children's Hospital Camperdown. Services for children and adolescents with insulin-dependent diabetes mellitus in this State are most comprehensive in central Sydney. However, even these excellent services are not utilized fully by the children and their families. The annual cost of hospitalization for diabetes in the zero- to 19-years' age-group in New South Wales is estimated to be approximately +1.5 million. There needs to be an equally high standard of care for all diabetic children in the State; however, the utilization of services, as well as the services themselves, need to be improved and the cost-effectiveness of new services needs to be evaluated.
