Costs, outcomes and challenges for diabetes care in Spain.

Background: Diabetes is becoming of increasing concern in Spain due to rising incidence and prevalence, although little information is known with regards to costs and outcomes. The information on cost of diabetes in Spain is fragmented and outdated. Our objective is to update diabetes costs, and to identify outcomes and quality of care of diabetes in Spain.

Methods: We performed systematic searches from secondary sources, including scientific literature and government data and reports.

Results: Diabetes Type II prevalence is estimated at 7.8%, and an additional 6% of the population is estimated to be undiagnosed. Four Spanish diabetes cost studies were analyzed to create a projection of direct costs in the NHS and productivity losses, estimating €5.1 billion for direct costs along with €1.5 billion for diabetes-related complications (2009) and labour productivity losses represented €2.8 billion. Glycemic control (glycolysated hemoglobin) is considered acceptable in 59% of adult Type II cases, in addition to 85% with HDL cholesterol ≥40mg/dl and 65% with blood pressure <140/90 mmHg, pointing to good intermediate outcomes. However, annual figures indicate that over half of the Type II diabetics are obese (BMI >30), 15% have diabetic retinopathy, 16% with microalbuminuria, and 15% with cardiovascular disease.

Conclusions: The direct health care costs (8% of the total National Health System expenditure) and the loss of labour productivity are high. The importance of a multi-sectoral approach in prevention and improvements in management of diabetes are discussed, along with policy considerations to help modify the disease course.
