[The social and economic cost of diabetes mellitus].
OBJECTIVE
To evaluate the economic impact in terms of the direct costs (health care costs) and the indirect costs (effects on production caused by mortality and morbidity) of diabetes mellitus (DM) in the Canary Islands (Spain) during 1998.


METHODS
The approach used was to study the cost of the disease through looking only at people in the productive sphere (human capital). Direct and indirect costs were calculated by using costs of prevalence, i.e. the costs caused during 1998.


METHODS
Direct costs were broken down into hospital care, primary care, out-patient consultations, drugs and further tests; indirect costs, into premature mortality and time off work. Measurements and main results. The total cost of DM amounted to 6468.76 million pesetas (38.88 millio ), or the equivalent of 126 168 pesetas (758.28 ) a year for each known diabetic patient. Total direct cost of DM was 4011.51 million pesetas (24.11 million ), which amounts to 2.13% of health expenditure in the Canaries; or the equivalent of 78 240 pesetas (470.23 ) a year for each known diabetic patient. Direct cost of health care was 62% of the total cost. Total indirect cost was 2457.25 million pesetas (14.77 million ), 38% of the total cost.


CONCLUSIONS
Despite the conservatism of the approach, in that the study omitted costs linked to pain and suffering, permanent disability or home care by family members, the high social and economic cost of DM patients calls for cost-effectiveness studies that would permit a more transparent debate on this question.
