In practice

Your coordinators spend their days chasing study leads by phone. Delfa's agents call each lead, run the prescreen, take a full medical history and book the qualified ones for a visit, updating the CTMS as they go.

A participant mentions a possible side effect during a reminder call. The agent hands the conversation to site staff right away, and the call, notes and update sit in the shared view for the coordinator to follow up.

A new study opens and your Spanish speaking patients are hard to reach. The agents prescreen in Spanish or English by voice, chat or text, and the site can be live on the new study within a day.
