1. To assess the effectiveness of a multi-faceted patient-centered intervention versus usual care in improving medication adherence as measured by proportion of days covered (PDC, primary outcome). This will be tested among IHD patients for statins, beta-blockers and clopidogrel in the year after PCI and among rheumatology clinic patients chronically prescribed DMARDs. Hypothesis: The PDC for patients in the intervention arm will exceed the PDC for the usual care arm by a 10% absolute difference.
