This study showed a positive influence of the community pharmacist in reducing potential DRPs in the elderly. Future interventions should also focus on actual outcomes, including quality of life, morbidity and mortality.

In this vulnerable group of elderly patients potential DRPs frequently occur. Community pharmacists can play an important role in the identification, assessment and prevention of potential DRPs in the elderly. It is useful to investigate which part of potential DRPs can be avoided by the intervention of the community pharmacist in collaboration with the prescriber and the patient.
