Jerome Osheroff, PCOR CDS-LN Steering Committee Co-Chair

Jerome A. Osheroff, MD, FACP, FACMI is the PCOR CDS-LN Steering Committee co-chair. A general internist by training, he has spent the past 3 three decades building understanding of care delivery information needs, and helping ensure that people, processes and technology are successfully applied to fulfilling these needs better. Osheroff is the principal of TMIT Consulting, LLC, a firm he founded in 2011 to develop and implement pathways to better healthcare outcomes for care delivery organizations, government agencies, quality improvement organizations and HIT vendor clients.  He is recognized internationally as a leader in developing and applying health IT and clinical decision support-enabled approaches to improving health and care delivery.  Osheroff articulated the “CDS 5 Rights” framework, recommended by CMS as a best practice for improving patient care.  Osheroff has led work with government agencies, provider and health IT vendor organizations, clinicians and care teams, and others to develop many valuable healthcare quality improvement resources, most recently, HRSA's Guide to Improving Care Delivery Processes and Outcomes. He guides use of these strategies and tools in a growing portfolio of successful QI initiatives that are significantly improving care processes and outcomes. For the decade prior to starting TMIT, he was Chief Clinical Informatics Officer for Thomson Reuters Healthcare, where he ensured that their decision support offerings were optimally responsive to clinician, patient, and management information needs, and that they measurably improved healthcare outcomes.
