GARJON, F. J.. Prescribing drugs to patients receiving out-patient care. Anales Sis San Navarra [online]. 2009, vol.32, n.1, pp.11-21. ISSN 1137-6627.

Drug prescription has evolved to deal mainly with chronic diseases. Nowadays, repeating prescriptions using computers results in problems if this is not done with adequate control. Steps proposed for appropriate prescription are: defining the problem; specifying the objective; selecting the drug; initiating therapy with appropriate details; giving information; regular evaluation; considering cost; and using tools to reduce errors. Published recommendations for prescription, which have focused on elderly patients, include: avoiding polypharmacy; carrying out a regular medication review; stopping any current drugs that are not indicated and prescribing new drugs that have a clear indication; avoiding drugs that have deleterious effects; using dosages that are suitable for the age and renal function; using simple drug regimes and appropriate administration systems; considering non-pharmacological treatments; limiting the number of practitioners prescribing for each patient; and avoiding treating adverse drug reactions with further drugs. Examples of compliance with those recommendations in the Navarre Health Service, extracted from the prescription information system, are provided. The measures for improving prescription are: education, auditing, collaboration between health professionals and use of electronic tools.
