Pharmaceutical Care Network Europe

The Pharmaceutical Care Network Europe (PCNE) was established in 1994 by a number of European pharmaceutical care researchers. It became an official association (under Dutch law) in 2004.

Medication Review Drug-related problem classification Guidelines and Indicators

PCNE Working group on drug-related problems.

Drug-related problems are one of the cornerstones of pharmaceutical care. Therefore the working group on Drug-related problems develops and evaluates a DRP-classification.

In September 2009 the working group on Drug-related problems of the Pharmaceutical Care Network Europe has been officially estabished, although it existed already informally since 2001. The working group is currently chaired by Dr. Nina Griese and Dr. Tommy Westerlund and Dr. Nejc Horvat. PCNE also developped a definition of a DRP, on which the classification is based:

"A Drug-Related Problem is an event or circumstance involving drug therapy that actually or potentially interferes with desired health outcomes."

16-6-2017: Classification V 8.01

Version 8.01 is ready and available, incorporating some validation results of V7.0, and correcting one omission in V8.0. Version 8.0 and V 8.01 are not compatible with earlier versions, due to some fundamental changes. The version 8.01 will now be validated by an international group of experts in the summer and fall of 2017.

20-7-2016: Classification V7.0

Please note that Version 7.0 now only will have limited support, and previous versions are no longer supported, but can still be downloaded. V7.0 is not compatible with earlier versions, due to some fundamental changes.

PCNE Working Symposium on drug-related problems in 2009

The the definition of drug-related problems, and the new version of the PCNE-DRP classification have been extensively discussed during an PCNE Working Symposium on Drug Related Problems in Geneva, on the Monday 2nd November 2009. There were 18 experts present who discussed definitions, the new version (V6) of the PCNR DRP classification and validation issues.

The different abstracts, presentations and reports are available from Working Symposium 2009.

In 2017, a new discussion round was held between experts, and thus the start for the creation of a new version was given. One of the essential new elements will be the way that the proposed interventions are presented, and what the acceptance of the intervention was. This version 8.01 is the current version and previous versions are no longer supported.

Additional information can be obtained from the professional secretariat of the PCNE.
