Lauge Sokol-Hessner, MD

Dr. Lauge Sokol-Hessner is a hospitalist and a Clinical Associate Professor of Medicine at the University of Washington (UW) in Seattle, Washington. Dr. Sokol-Hessner has led communication and resolution program work in several ways: communicating with patients and families after adverse events; leading a medical center’s peer review program (as the former Senior Medical Director of Patient Safety in the Department of Health Care Quality at Beth Israel Deaconess Medical Center, in Boston, MA); a member of the leadership team for the Massachusetts Alliance for Communication and Resolution after Medical Injury (MACRMI); and coaching and supporting several hospitals in Eastern Massachusetts who are implementing CRPs.

Along with his colleagues, he has also led work to expand the definition of preventable harm to include not only physical harms – such as unexpected deaths or injuries from medical errors – but also those that are non-physical – such as the emotional and psychological impacts and negative effects on trust and therapeutic relationships that can occur after adverse events. He believes healthcare organizations and professionals should aspire to a more reliable “practice of respect” in healthcare, which includes implementing and sustaining CRPs to ensure communication after adverse events is proactive, honest, and respectful.

Aside from his clinical, quality/safety, and CRP-related work, Dr. Sokol-Hessner’s career has focused on helping develop and coach the next generation of healthcare leaders. He regularly teaches how to lead change and just prior to his recent move to UW/Seattle he was the Program Director for the Harvard Medical School (HMS) Fellowship in Patient Safety and Quality, and a Course Director for the HMS Masters in Healthcare Quality and Safety in Boston, Massachusetts.

When not working he spends time with family and friends, and seeks out long-distance biking and the mountains in all seasons.
