5-11-2017: Classification V 8.02

Version 8.02 is ready and available, incorporating some validation results of V7.0, and correcting some minor issues in V8.0 and V 8.01.
Please note that Version V 8 is not compatible with earlier versions, due to some fundamental changes. The version 8.02 is being validated by an international group of experts . This version is also available in Mandarin Chinese and Traditional Chinese (see below).

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 defined a Drug-related propblem, on which the classification is also based:

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


PCNE Working Symposium on drug-related problems in 2009

The the definition of drug-related problems, and the 2009 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. After a quick validation some minor changes were implemented, and now Version 8.02 is the current version and previous versions are no longer supported.

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

Please note that the latest version is V8.02 now. Previous versions are no longer supported, but can still be downloaded.The versions 8 are not compatible with earlier versions, due to some fundamental changes. But V8.02 is compatible with V8.0 and V8.01. The English edition of this version will be validated. There is a Mandarin Chinese translation of this version.

There is a Spanish, Turkish and Croatian version version of the Classification V6.2. These versions also are no longer supported by PCNE but have proven their worth in several projects.

Please note that there is a copyright on the material, and you should inform the PCNE secretariat if you want to use or publish the Classification or related materials (any version).

The classification has changed significantly since its first version. A list of the changes can be found here DRP classification update history.
