Digital Scholar Webinar: Leveraging Medical Health Record Data for Identifying Research Study Participants: Practical Guidance on Using Clinical Research Informatics Applications in Your Research

Research Participant Recruitment
Clinical Research Informatics


This webinar will highlight three applications available at USC, CHLA and LA County DHS that assist researchers with identifying prospective study participants. Study recruitment remains one of the major challenges to successful clinical and translational science. Medical health record data provide a new source for identifying prospective study participants that fit the eligibility criteria. The speakers will introduce three applications (TriNetX, i2b2, and SHRINE) and provide a step-by-step guide for accessing and using this type of data.


Juan Espinoza, MD, FAAP, Assistant Professor of Clinical Pediatrics, Keck School of Medicine of USC, Physician and Director of Clinical Research Informatics, Children’s Hospital Los Angeles; and Mark Abajian, Applications Lead, Clinical Research Informatics, SC CTSI

Learning Objectives

  • Describe the characteristics and strengths of the three applications: TriNetX, Shrine, and i2b2
  • Understand required steps for accessing and using the data provided by the applications, including the regulatory process
  • Describe potential weaknesses of these three applications and how to address them
