CAVEATS
Less-than-ideal study methods
This trial was an open-label, unblinded study. The investigators who adjudicated critical events were blinded to the treatment allocation, but some events, such as minor bleeding and medication discontinuation, could be self-reported by patients. In addition, the investigators used a less-than-ideal method (opaque envelopes) to conceal allocation at enrollment.
CHALLENGES TO IMPLEMENTATION
Implementation may require changing a cardiologist’s prescription
Implementing this practice change is facilitated by the fact that clopidogrel is currently less expensive than the newer P2Y12 blockers. However, after ACS and PCI treatment, cardiologists usually initiate antiplatelet therapy and may continue to manage patients after discharge. So the family physician (FP) may not be responsible for the DAPT switch initially. Further, switching may necessitate coordination with the cardiologist, as FPs may be hesitant to change cardiologists’ prescriptions. Lastly, guidelines currently recommend using the newer P2Y12 blockers for 12 months.2
