Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Source documents (e.g., medical records and study-specific data collection tools) provide evidence of the existence of participating subjects and confirm the integrity of the data collected. Source documents shall be archived at the investigator’s study site. Data transcribed from source documents and reported on the CRF or entered into the eCRF must be consistent with the source documents. Any discrepancies must be explained. Depending on the study, the investigator may require the provision of prior medical records or transfer records. In addition, current medical records must be available.
