Brief Summary:
In an aging population, most seniors suffer from multiple chronic conditions. When the number of medications taken is ≥5 (polypharmacy), the burden of taking so many together can do more harm than good. This study will test a program focused on medication reduction involving patient, pharmacist and physician using current technology aimed at reducing the harms of polypharmacy. Reducing the risk of adverse effects from drugs or the interactions between them involves prioritizing the most important ones according to the patient's preference and stopping those which may no longer be necessary. Reducing the dose also reduces the risk of drug side effects. Patients, aged over 69 years taking ≥5 medications, will randomly receive the program immediately or at 6 months. The program involves information gathering from the patient, medication review with the pharmacist and then a consultation with the family doctor focused on discontinuing/reducing the dose of medications where possible using a 'pause and monitor' framework to assess the need for restart. An electronic program that detects drug adverse effects and flags potentially inappropriate medications will be integrated into a clinical pathway incorporating monitoring and follow up systems. This study will examine effects on patient and health relevant outcome measures as well as patients' and clinicians' experiences of the program. The results will be used to determine whether this system can be implemented as part of routine preventative care in older adults.

Condition or disease Intervention/treatment Phase
Comorbidity Medication Therapy Management Other: TAPER program Not Applicable

Detailed Description:
Patients will be randomized 1:1 to receive the intervention at study start or delayed appointment 6 months later. The intervention includes initial baseline data collection from the patient including data on demographics, medications, and illness characteristics. The patient will then attend an appointment with a pharmacist to review medications appropriate for discontinuation/dose reduction, after which the patient will meet with his/her family physician to discuss patient preferences for discontinuation/dose reduction. Follow up appointments will take place at one week, 3 months and 6 months (study end). Questionnaires and a semi-structured interview will take place at the 6 month appointment. After six months, the control group will be offered the intervention.
