Developing a measure of polypharmacy appropriateness in primary care

A systematic review and expert consensus study has identified 12 implicit indicators for appropriate polypharmacy, including indication for drug, no effective non-pharmacological alternatives available, no clinically significant drug-drug interactions, effective for indication, and not likely to be sub-therapeutic or toxic, based on the dose, route and dosing interval for the age, renal and hepatic status of the patient. Importantly some patient-centred indicators are included such as patient is clear about the drug regimen and patient adheres to the drug schedule.

Collaborative intervention between pharmacists and physicians on elderly patients

Collaborative interventions between pharmacists and physicians were shown to improve medication adherence and Medication appropriateness Index (MAI) scores of the elderly patients in this randomised controlled trial. The authors conclude such services should be implemented in all hospitals, especially in countries where pharmacists are still not playing a substantial role in patient care.
