What is Fax Data Collection?
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.
How does it work?
- 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.
- DataFax creates Quality Control Reports containing automatic queries for
overdue visits and missing CRF pages plus all outstanding queries created by
data management staff and edit checks, and sends them by fax or email to the clinical sites.
The sites then correct the original paper CRFs and refaxed them to the DataFax server.
- 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.
