ABSTRACT
The Epidemiology Data Center at the University of Pittsburgh has developed a standard set of data management procedures, reports, and computing configurations for use on multicenter research projects. Based on budget restrictions and study design considerations, a project-specific data management system can be quickly constructed by utilizing appropriate components from the EDC tool kit: the PoP software system for the computerization of the database from paper forms to data entry screens; program shells for telecommunication and backup procedures; and procedural documents for providing the necessary training materials for centralized or decentralized processing environments. The EDC data flow specification provides quality control assurances from entry through statistical analysis.
