The CRA supervises (known in the industry as monitoring) the clinical sites at random visit days to ensure that the site is respecting ethics and completing the CRFs appropriately.
During a monitoring visit the CRA will verify various patient data included in the eCRF by the physician / investigator or CRC (the physician’s nurse coordinator). This process, called source data verification (source being the electronic patient file) checks whether the study has been carried out following applicable laws and regulations.
