We recently completed an SIV and a question came up from the study monitor. "How do you question healthy study volunteers to honestly admit or present to the coordinator that they have recently taken medication prior to or during a study period"?. Due to study criteria or restrictions, healthy study volunteers are withholding or denying taking medications. Our sites present this questions to the subejcts, in addition also further query them and give them an example. "Have you recently taken tylenol for headache, musclepain..etc"? Also,iriterate to them that giving this information will not be the reason for exclusion unless it is in the window of wash-out period prior to taking the study medication.
Any suggestions or helpful comments to improve this process?
