Data management and other logistical challenges for the GEMS: the data coordinating center perspective

Area of Science:

• Epidemiology
• Global Health
• Data Management

Background:

• The Global Enteric Multicenter Study (GEMS) is the largest epidemiological study on diarrheal diseases in children under five.
• The study was conducted across diverse geographical and geopolitical settings in 4 African and 3 Asian countries.

Purpose of the Study:

• To outline the data management, administrative, and statistical support provided by the Cooperative Studies Program Coordinating Center to the GEMS study.
• To highlight the challenges encountered in managing a large-scale, multicenter epidemiological study.

Main Methods:

• Centralized data management operations were established to handle data from multiple international sites.
• Data transfer protocols and data cleaning procedures were implemented to ensure data integrity.
• Administrative and statistical support was provided throughout the study's duration.

Main Results:

• The study successfully collected a large volume of data from the participating countries.
• The data coordinating center provided comprehensive support, enabling the study's progress.
• Geographical and geopolitical differences presented significant administrative challenges.

Conclusions:

• Effective data management is crucial for large-scale international health studies.
• Centralized coordination presents unique challenges in multicenter epidemiological research.
• The GEMS study highlights the importance of robust data support systems in global health initiatives.
