[Blood donation in the Balearic Islands. Analysis of supply and demand of blood from 1982 to 1987].
BACKGROUND
The supply and consumption of blood products in the autonomous community of the Balearic Islands were evaluated for the years 1982 to 1987 to assess the degree of hemotherapy coverage.


METHODS
The registries of blood banks from 1982 to 1987, the clinical records of patients with congenital coagulation deficiencies and the registries of the hospital pharmacies and pharmaceutic distributing agencies were reviewed.


RESULTS
The rates of use per product (units) and per one thousand population were as follows: red blood cells 22-25, platelets 0.8-3.2, transfusional plasma 0.5-2.8, and cryoprecipitates less than 0,2. The consumptions of albumin and gammaglobulins were 80 and 7.7 kg per one million population, corresponding to 3.200 and 1.540 I of plasma, respectively. The consumption of factor VIII was 1.3-0.9 international units (IU) per inhabitant, in highly of very highly purified form, corresponding to 18.500-12.857 I of plasma.


CONCLUSIONS
The results show that a supply of 25-27 blood donations per one thousand population and per year and with a fractionning of 80%, yield 5.000 I of plasma per one million population. This fulfils the needs of all blood products, except those of highly or very highly purified factor VIII.
