[Prerequisites for electronic systems evaluating safe and effective drug therapy. A contribution to the Action Plan of the Federal Health Ministry].

Evaluation of effective and safe drug therapy assisted by electronic systems is based on certain prerequisites, including structured data of drugs and from patients. These prerequisites were identified in a workshop within the scope of the National Action Plan and have been reported in a 7+1-point plan: medicinal product data must be correct and up-to-date based on the summary of product characteristics approved by the responsible authorities. Product data must be available in an agreed textual structure and must use defined semantic elements within this structure. Identifiers must be allocated to all drugs and substances in order to enable unique identification and exchange across systems. Semantic structures of the product data, on the one hand, and of patient data, on the other, must be defined across system boundaries and for the whole German national health care system, and be available to every stakeholder, up-to-date, and preferably freely accessible. This consensus regarding content and structural conventions is a prerequisite for other scenarios in the health care system, such as transmitting individual case safety reports without system and media discontinuity, and is currently of great importance with respect to the European legislation on pharmacovigilance, which will be implemented nationally.
