Conferences Working groups

PCNE Working group on drug-related problems

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

In September 2009, the working group on Drug-Related Problems of the Pharmaceutical Care Network Europe has been officially established, although it existed already informally since 2001. The working group is currently managed by Dr. Tommy Westerlund (Sweden), Dr. Nejc Horvat (Slovenia) and Dr. Ina Richling (Germany).

10-5-2020: Classification V 9.1

Version 9.1 is ready and available, it now includes a simplified causes domain for seamless care. Please also note that the contact email address has been adapted, due to organisational changes in the working group and PCNE.
Please note that Version V8 is not compatible with earlier versions, due to some fundamental changes. But V8 is more or less compatible with the Version 9, with the help of a conversion table (C8 is new, C9 is the old C8). The version 9.1 is the result of an international validation round of V9.0. It has been validated by an international group of experts and is available in English, Traditional Chinese, German, Turkish and Croatian. V9.0 is also available in Mandarin Chinese, Montenegrin, Turkish and Indonesian. Version 8.03 is available in Traditional Chinese and Turkish (see below).


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