Returned tablet count

Compliance with medication/device use (by the study subject) should be assessed in all studies. If supplies are dispensed to subjects for self-administration, methods to assure compliance (e.g., diary cards, instructions on labeling, supervised administration) and methods to check compliance (e.g. tablet counts, plasma/urine assays, diary card review) must be in place. At each study visit, the study subjects should be asked to return all unused supplies and empty containers to the investigator, who will check the supplies for assessment of compliance and store them for return to the sponsor/ CRO. The monitor will review all relevant documents (e.g. source documents, CRTs, medication/ device inventory, dispensing forms) to ensure that the data in the CRFs reflect the subjects compliance with the study medications/devices.
