Information systems for the analysis of drug prescriptions in Spain

The Spanish National Health Service, largely represented by INSALUD, covers at present over 98% of the Spanish population. Services are free at the point of delivery with exception of prescription charges. The patients contribution towards the price of their medicines is approximately 40% of the cost of the drug for most ethical preparations. Non-prescription drugs are not reimbursed by the National Health Service. Pensioners and the disabled are exempt from prescription charges. Prescription analysis or monitoring is possible within INSALUD because of the necessity to reimburse pharmacists for the prescriptions they dispense, monthly batches of prescriptions are processed. The Drug Data Bank possesses three databases that may be used for prescription analysis, these are ESPES, ECOM and PACTIV. Information from these databases is used by external workers in: drug Monitoring Centres for Adverse Drug Reactions; the Spanish Collaborative Study on drug-induced birth effects; drug utilization research workers; INSALUD also produces reports on drug prescribing and these have a particular emphasis on expenditure; the General Directorate of Pharmacy also use these databases for their policy making on issues related to, and derived from prescribing.
