Randomisation

Timescale for PCI after randomisation

Q. If a patient is randomised to PCI + OMT, how long after randomisation should the procedure occur?

A. It is important that the procedure take place no more than two weeks after randomisation to reduce the possibility of events occurring between randomisation and the procedure. It is suggested that a PCI slot is booked prior to randomisation and that the patient is randomised at most 2 weeks prior to that date. The best way is to always plan for the outcome of randomisation to be PCI + OMT. If the allocation is PCI + OMT, the patient has notice of the procedure. If the allocation is OMT alone, there is time to re-assign the slot. However, this is just a guide and things may work differently at your site.
