Epidemiology

 

Mission

The mission of the Epidemiology Core is to perform epidemiological research within Vitalant on blood donors toward assuring a safe and adequate blood supply; support additional research and operational projects requiring epidemiology, statistics, and database analytics expertise within VRI and more broadly to Vitalant, Creative Testing Solutions and their collaborators; and provide service as a data coordinating center for extramurally-funded projects. The Epidemiology Core maintains a donor/donation research database and a blood donation laboratory-screening database for all centers in the Vitalant network, provides ad hoc epidemiology, statistical, and analytic consulting to VRI and non-VRI collaborators, and offers data coordinating and management services for projects with extramural funding.

Epidemiology and Statistics Consultation Support

We provide consultation regarding study design, human subjects research requirements, questionnaire content, sample size calculation, data collection and management, and statistical analysis techniques on an ongoing basis. Complete statistical analysis of projects as well as manuscript review and editing are also provided.


Survey Design and Implementation

The Epidemiology Core team can rapidly develop and deploy surveys on mass scale utilizing the Qualtrics platform. Expertise developed during the SARS-COV-2 pandemic allows our continued focus on quickly capturing data during emerging infectious disease outbreaks by collaborative development of survey tools and rapid implementation. Our team has expertise in survey distribution via the native Qualtrics environment and in combination with other management tools such as Eloqua.


Database Management and ETL Pipeline Support


We provide data collection and management, database and data linkage support, ETL pipeline management and statistical analysis to colleagues and collaborators for projects large and small. Data are securely maintained in encrypted, restricted access environments and managed by team members with more than 30 years of combined experience using SAS, Stata, SQL, R, Python, ArcGIS, and other data visualization tools.

Data Coordinating Center (DCC) Support


We provide complete study management and logistical support, including design of study management systems (SMS), electronic data capture (EDC) systems, electronic case report forms (eCRF), and routine study monitoring for research projects of any size.

We provide complete study management and logistical support for research projects of any size.
