BioSense v2.0 Webinar: Data Quality Checks and Assurance – International Society for Disease Surveillance


Thursday, May 22, 2014 – 3:00pm – 4:00pm EDT


ISDS and the BioSense Redesign Team (more information about this webinar series)


Caleb Wiedeman, MPH, Epidemiologist, Tennessee Department of Health

Harold Gil, MSPH, Applied Public Health Informatics Fellow, County of San Diego Public Health Services


Presenters Caleb Wiedeman and Harold Gil will describe some of the processes their organizations use to ensure the quality of data in BioSense v2.0. First, Caleb Wiedeman will review his normal routine of verifying data quality, including checking the front end of the BioSense v2.0 application for aberrations and drops in visit counts, linking front-end data to the back end using R, and using phpMyAdmin to check daily files. This portion of the presentation will focus on Tennessee’s system and the data they receive from six facilities within a single health system.

Following the data quality checks segment, Harold Gil will more broadly discuss the User Community Extension Project (UCEP) group’s work on data quality. The UCEP has focused on developing and sharing tools that complement BioSense functionality and scale across jurisdictions. Webinar attendees will learn about the data quality script the group has been developing over the last several months.
