N-CANDA data integration: anatomy of an asynchronous infrastructure for multi-site, multi-instrument longitudinal...

Area of Science:

• Neuroscience
• Adolescent Development
• Data Management

Background:

• Adolescent brain development research requires robust data collection infrastructure.
• The National Consortium on Alcohol and NeuroDevelopment in Adolescence (N-CANDA) faced challenges in establishing a timely data collection system.

Purpose of the Study:

• To describe the innovative data collection infrastructure developed by N-CANDA.
• To highlight features that enable efficient and secure data management for longitudinal studies.

Main Methods:

• Implementation of secure, asynchronous data transfer using a revision control system.
• A two-stage import process into a longitudinal database.
• Utilizing a script-controlled web browser for retrieving data from external neuropsychological test batteries.

Main Results:

• The N-CANDA system allowed data collection to commence before the full database infrastructure was deployed.
• Records were collected within 86 days of funding and 35 days after finalizing instruments.
• The system reduced project start-up time by several months, enabling early data acquisition.

Conclusions:

• The N-CANDA data collection system's innovative features significantly accelerated project initiation.
• Asynchronous data transfer and a staged import process are key to reducing start-up delays in multi-site research consortia.
• This infrastructure supports efficient and secure data management for adolescent neurodevelopment studies.
