Should my organization require faculty disclosures in writing?

You can, but the ACCME states that verbal disclosure is also an acceptable way to receive financial information from those in control of content in accredited CE.  More importantly, “Providers must be able to verify for the ACCME that the individual was given the ACCME definition of an ineligible company and was informed that they must disclose all financial relationships with ineligible companies over the 24-month period prior to their involvement in accredited CE.”
