Data will be collected from a variety of sources, including surveys, electronic medical records, medical and functional tests, and staff reports. Data will be entered and double-verified in password-protected spreadsheets sand databases stored behind a firewall. Any electronic medical records data captured will use secure data transfer and HIPAA-compliant protocols approved by the University of Oregon IRB. Staff reports will be forwarded directly to project data managers. All personal data will be identified by numbers rather than names. Interim reports of project results will be made to the Data and Safety Monitoring Board.
