Finding DRP classifications by computerized search of the biomedical literature with the help of PubMed proved to be difficult. No classification could be found that met all of our criteria for an optimal system. Few classifications have been validated. Three have been tested as to their usability in practice and internal consistency. The Pharmaceutical Care Network Europe system Version 4 comes closest to the defined requirements.

Background Medication review is important in an era, in which polypharmacy is increasing. To date, no agreed international definition of medication review exists. Objective The aim was to reach agreement on an internationally applicable definition of medication review. Setting An international group of experts in medication review. Methods A working group of the Pharmaceutical Care Network Europe (PCNE) was established to agree on a definition including a classification of medication review. First, a survey with the aim of systematically gathering viewpoints on a definition of medication review was conducted. Second, a workshop was held to achieve an agreement. Finally, during the General Assembly of PCNE, the definition was approved. To ensure a better understanding of the scope and the considerations behind the definition, a position paper was created. Main outcome measure An internationally agreed definition of medication review. Results 58 PCNE members from 20 different countries completed the online survey. Then, 22 participants from 11 different countries (not only PCNE members) elaborated the final definition during a workshop. The final PCNE version agreed was: "Medication review is a structured evaluation of a patient's medicines with the aim of optimising medicines use and improving health outcomes. This entails detecting drug-related problems and recommending interventions". Overall, the consensus process included 225 people from 35 countries and resulted also in a classification of medication review taking into account the type and source of available information. Conclusion Involvement of an international community from research and practice and the use of a systematic process led to an agreement on the term medication review and on a classification valid for all settings and professions.

It was possible to paraphrase definitions of PhC using a standardised syntax focusing on the provider, recipient, subject, outcomes, and activities included in PhC practice. During a one-day workshop, experts in PhC research agreed on a definition, intended to be applicable for the present time, representative for various work settings, and valid for countries inside and outside of Europe.

We report a fairly high prevalence of swallowing difficulties in polypharmacy patients attending their community pharmacies. Pharmacists have to interview patients on their swallowing difficulties in a more systematic way, support patients in finding solutions and refer them to their physician if necessary to ensure continuity in care.
