The continued escalation of clinical trial costs is becoming a public health concern. During the past decade, medical research funding peaked and there is growing concern that there may be insufficient resources to test many promising medical products. Recent changes in the regulatory environment create opportunities for the use of medical informatics to improve clinical trial operations and reduce costs. We report on a Medical Informatics Europe 2016 workshop conducted during the Health-Exploring Complexity (HEC) 2016 conference. We review presentation given on Secondary Data Use, eSource, and Data Quality in Clinical Trials and report on the workshop's discussions.
