Outcome Measures

Primary Outcomes (2)

  • Population-level trends in age- and sex-standardized proportions of clopidogrel, ticagrelor, and prasugrel initiators over time

    To evaluate temporal trends in the age- and sex-standardized use of clopidogrel, ticagrelor, and prasugrel among adults initiating P2Y12 inhibitor therapy after acute myocardial infarction in Germany and the US between 2011 and 2024.

    2011 to 2024

  • Population-level trends in consumer price index-adjusted net 12-month costs of clopidogrel, ticagrelor, and prasugrel over time

    To evaluate temporal trends in the consumer price index-adjusted 12-month treatment costs of clopidogrel, ticagrelor, and prasugrel in Germany and the US between 2011 and 2024.

    2011 to 2024

Other Outcomes (5)

  • Population-level trends in age- and sex-standardized 1-year cumulative incidence of MACE over time

    1 day after cohort entry date until the first of outcome, disenrollment, 365 days after cohort entry.

  • Population-level trends in age- and sex-standardized 1-year cumulative incidence of bleeding-related hospitalizations over time

    1 day after cohort entry date until the first of outcome, disenrollment, 365 days after cohort entry.

  • Estimated population-level drug cost savings associated with replacement of ticagrelor with prasugrel in clinical practice in the US

    Q4 2019 to Q4 2024
