  1. BioMedical Informatics CoreUpdate ICON Annual Meeting, April 22, 2013 Ron Horswell, PhD Associate Professor Pennington Biomedical Research Center

  2. BMI Core Functions • Design, Create, Maintain data entry packages for projects requiring prospective data collection. • Largely done with RedCap • Connie Murla (PBRC) • Daniel Lorio (PBRC) • Extractions of data from large, existing databases. • Largely from the LSU HCSD’s DMED warehouse • Ron Horswell (PBRC) • Elizabeth Chesteen (PBRC) • San Chu (PBRC) • Jay Besse (HCSD) • Yong Yi (HCSD) • PI’s, Co-PI’s for some projects • Participate in ICON “interest groups”
