Pharmaceutical care involves decision-making based upon communication and judgements to avoid, initiate maintain or discontinue pharmacotherapy. After establishing patient-pharmacist relationships and implementing collaboration with physicians based upon consensus guidelines, relevant information should be collected and processed in order to determine drug therapy problems and desired treatment outcomes. This paper describes in short the development of a 'care concept' for pharmaceutical care and focuses in particular on the fully integrated functions of a pharmacy automation system (Pharmacom) for documenting relevant data and supporting the processing of drug therapy.
