Having looked at some of the main metrics that sponsors will want to keep track of from the patient recruitment vendor, the next stage in the process is to discuss the results and attempt to institute a process of continuous improvement.

In the marketing world, the concept of ‘beat the control’ is one where you have a control advert that performs best, then you put other ads against it in a series of split tests – the ultimate goal being to ‘beat the control’ and thus have an ongoing cycle of improved results.

Sponsors, CROs, and Research Sites can help with this process by providing feedback based on any learnings they have regarding what works best for attracting patients – in particular focusing on why patients might fail a pre-screener or drop out of a trial. This kind of collaboration is a key driver of a successful recruitment campaign.
