Myocardial infarction prescription adherence duration study: MIPAD
To reduce the morbidity and mortality of post-myocardial infarction (MI) patients through improved long-term cardiac medication adherence. The specific objectives are to: (1) assess the impact on long-term cardiac medication adherence following the implementation of standardized process to increase in discharge prescription length to 90 days with 3 repeats in post-MI patients as compared to usual care; (2) assess the cost implications of this new strategy as compared to usual care; (3) compare clinical outcomes between longer (>60 days) versus shorter prescription durations; (4) collect baseline information to inform a multi-centre interventional study (i.e. simple monthly proportions of 1-year adherence by hospitals in Ontario).
Quasi-experimental, controlled interrupted time series design
Increased proportion of patients with high adherence (proportion of days covered (PDC) >80%) for the combined four cardiac medications classes at one year.
