3.3 Secondary outcomes
A total of 310 interventions were carried out (table 3) in 251 patients.
The most common intervention (n=203 out of 310, 65.5%) was when the
maximum duration of the combined therapy was not defined nor documented.
The second reason for intervention counted for 19.4% of cases in which
there was no (more) indication for the combined therapy and therefore
ASP intervened to discontinue either antiplatelet drugs or oral
anticoagulant therapy. Interventions due to dose adjustment counted for
8.1% of the total interventions. Lastly, seven interventions (2.3%)
were to switch between OAC’s and the reason for switching was due to
interaction, reduced kidney function or wrong indication.
