Per  Misdirections in Informed Consent - Impediments to Health Care Innovation Misdirections in Informed Consent - Impediments to Health Care Innovation - Alternative Formats by David Asch et al. Why might an IRB be reluctant to grant an informed consent waiver to QRS' proposal "to randomly assign patients to either the whimsical card, the pre-scheduled-appointment card, or usual messaging"?  is it agreeable with Asch et al. that a waiver should be available in this situation? If so, do you believe that a waiver should be available for any study that randomly assigns participants to two low-risk interventions commonly used in clinical practice?
