Designing and Implementing a Web-Based Data Management System for a MultiSite Longitudinal Intervention Study


Warmoth, E. K., Courtney, L. P., Rodan, M., Katz, K., Subramanian, S., & Kiely, M. (2006, May). Designing and Implementing a Web-Based Data Management System for a MultiSite Longitudinal Intervention Study. Presented at International Field Directors and Technologies Conference, Montréal, Canada.


To successfully implement a complex, multisite randomized study, it is essential to design a user-friendly data management system (DMS) to assist field staff with managing participant activities efficiently. This is a two-part presentation addressing the design and technical implementation of the DMS for the Girl-Talk for Teen Moms Study, being conducted in the NIHDC Initiative to Reduce Infant Mortality in Minority Populations in Washington, D.C. (NIHDC Initiative).

Field staff from multiple sites use the DMS to manage up to 100+ possible activities for each participant over the course of their two-year enrollment in the study. The DMS monitors all activities for screening, recruitment, evaluation/interviews, interventions, and follow-up activities, with a complex series of triggers that lead from one activity to the next. Because minors are enrolled in this study, careful monitoring of parental consent is critical for field staff. This presentation will describe the steps taken in designing the DMS based on a complex series of study activities.

The second part of the presentation will focus on the implementation of the DMS. Previous studies in the NIHDC Initiative utilized a PC-based data management system requiring nightly data transmissions to and from each site to synchronize study data. In the current studies this model was reconsidered and a Web-based data management system was implemented. We will compare the Web-based DMS with the PC-based system and describe the efficiencies obtained by moving to a Web-based DMS.

Advantages of a Web-based application over an application installed on users’ local computers include the following: Real-Time; Data Access; Simplified Software Management; Data Security; Anytime / Anywhere Access.

Several features of the Web-based DMS will be discussed, including the role-based menu, events tracking, appointment scheduling and calendaring, report generation, access to study documents, and uploading of data files to RTI servers.
