Documentation of pharmaceutical care has been advocated for close to 30 years for a number of reasons, not least to enable patient follow-up of managed or resolved drug-related problems (DRPs). The first pharmaceutical care documentation was performed in the US, followed by the Netherlands and Sweden, and has also been performed in Canada, in additional countries in Europe and in Australia . The creation of DRP classification systems was necessary for a systematized documentation of pharmaceutical care , which in turn was facilitated by the development of computerized documentation instruments, incorporated into software programs. Statistics on documented DRP data and free text information may serve as educational material for continuing professional development , aimed at further improving the DRP detection skills. The documentation may also be used to get a deeper understanding of both causes and characteristics of DRPs and to demonstrate the potential societal cost savings of pharmaceutical care .
