Do not mistake fax data collection for a manual process. The clinical sites typically complete paper CRFs even when required to subsequently enter the data into an EDC system. Instead they can fax the CRFs to a DataFax server at the study coordinating center where the fax is received and read by intelligent character recognition software which performs data entry for them.

  • Paper case report forms (CRFs) are completed and faxed from the clinical sites participating in a trial, using standard office fax machines. No computer equipment is required at the clinical sites.
  • When the CRFs are received by a computer running DataFax at the study coordinating center they are automatically indexed and sent to the appropriate study database.
  • Before being stored in the study database DataFax ICR (intelligent character recognition) scans each CRF page and reads the data fields (including: numbers, dates, check boxes, and visual analog scales) to create an initial data record ready for human review.
  • Staff at the study coordinating center review the CRFs and data records using iDataFax split-screen Fax view and: correct any ICR errors, enter any text fields, and create queries to request missing data, corrections for invalid values and other information, as needed.
  • All CRF pages (including all versions of corrected forms) are stored along with the data records and queries in an integrated CRF image and data management system.
  • All modifications made to data records and queries are tracked by user, date and time; and audit trail reports can be created for specified users, patients, visits, pages and data fields.
  • A work flow management system tracks all CRF reviews and related tasks at the study coordinating center.
