Safer Dx team

Progress toward reducing diagnostic errors hinges upon our ability to overcome several unique measurement-related challenges, including operationally defining diagnostic error in real-world settings. Compounding these challenges is the fact that diagnostic errors typically emerge across multiple episodes of care. 

The compelling need for real-world evidence to demonstrate how we can measure and address diagnostic safety has led to the creation of the “Safer Dx Learning Lab.” Funded by the Gordon and Betty Moore Foundation, Geisinger and Baylor College of Medicine have come together to form this unique learning health system, a first of its kind, that takes a systematic approach to learn how health care systems can enhance the safety and accuracy of the diagnostic process. The multidisciplinary “Committee to Improve Clinical Diagnosis” at Geisinger advises and works closely with the Safer Dx Learning Lab.

This collaboration was initiated by Hardeep Singh, MD an international expert on patient safety and health IT issues based out of Baylor College of Medicine and the Houston VA Medical Center and Dennis Torretti, MD, associate CMO and chairman emeritus of the Division of Medicine at Geisinger. The initiative brings together Dr. Singh’s extensive research experience in this area and the motivated operational and clinical leadership at Geisinger to provide a significant opportunity to impact the field. 

Geisinger has harnessed a wealth of electronic data and will leverage this data to provide actionable information to improve clinical diagnostic quality. Baylor will build upon previous work in diagnostic safety and, along with Geisinger, will use a multidisciplinary, sociotechnical approach to improve measurement and feedback of diagnostic errors.



Dennis Torretti, MD

Dennis Torretti, MD, is the Associate Chief Medical Officer of the Geisinger Medical Center and chairman emeritus of the Division of Medicine at Geisinger. He is the executive sponsor of the Safer Dx Learning Lab and chair of the Committee to Improve Clinical Diagnosis. Since May 1996, as chairman of medicine, he was responsible for the delivery of clinical services, new program development, strategic planning, quality and innovation, clinical research, and residency and fellowship training within the Division of Medicine. He joined Geisinger in 1978 as a rheumatologist. Since that time, he has served in multiple roles within the organization and has been the recipient of several awards for teaching and clinical excellence.

Dr. Torretti established a diagnostic error workgroup at Geisinger in early 2015 and has since passionately pursued improving the diagnostic process at Geisinger. His vision for this initiative includes developing approaches that will provide feedback to providers, facilitate learning and reduce missed opportunities in making timely and accurate clinical diagnosis.
