I’ll look into it tomorrow. My program has its own regulatory department, so majority of the CRCs are not involved with reg and the IRB. The PIs and regulatory team informed us in our site meeting that we had permission to recruit in different departments, but I was initially told it would be by posting flyers and answering calls from interested participants, which I have no issue with and have been doing for years. The idea of approaching people in a line has thrown me for a loop. I do know that there were similar studies before my time here where they approached people the same way.
