The word omnichannel is often used in the context of marketing. Essentially it means that an organization or brand is being promoted through multiple methods, with each one retaining a consistency of messaging and appearance.
If we look at an omnichannel approach to patient recruitment, we might be talking about digital outreach, doctor outreach, community outreach, liaising with patient groups, utilizing lab test or claims data, and traditional advertising methods such as radio and press ads.
For our purposes the consistency of messaging and appearance may not be quite so important as for an organization that wishes to promote its brand for wider recognition.
Certainly we should retain the same colors and name of the study, and if there are messages we know are effective we should utilize them.
But the key to omnichannel for patient recruitment is to promote your trial using as many methods as make sense.
