[Evaluation of the supplies, usage, and necessity of blood components in Asturias (1990-1995)].
OBJECTIVE
To assess the effectiveness of the transfusion network in Asturias regarding the autosufficiency in the production of haemoderivatives and their usage, as well as the components of the transfusion procedure in the period 1990-1995.


METHODS
The procedure data and the results of donation, production and management and transfusion of blood components were analysed in a retrospective fashion.


RESULTS
The overall production of haemoderivatives in the years analysed, 1990 and 1995, was, respectively, 55.8% and 64% of the overall usage. These figures correspond to 113% and 138% when applied to blood components for transfusion, and 15.9% and 27% with regard to plasma derivatives. On the other hand, it was estimated that 113% of the necessary haemoderivatives were transfused, respectively, in 1990 and 1995, corresponding to 121% and 112% for blood components, and 108% and 149%, respectively, for plasma derivatives.


CONCLUSIONS
The Consultive Committee of the Community Blood Centres must establish a quality assurance programme for blood transfusion in order to monitor all the different steps of the transfusion procedure and to evaluate the accomplishment of the legal norms tending to achieve auto-sufficiency in blood derivatives.
