Dr. Sigmund has had a long-standing academic and clinical interest in perioperative medicine and high-quality care.

In 2016, Dr. Sigmund was named the Medical Director for Arthroplasty at Hospital for Special Surgery (HSS). In her role as the Medical Director, she oversees the medical care of postoperative arthroplasty patients by attending daily medical rounds. Rounds provide physician assistants, nurses, care managers and physical therapists the opportunity to collaborate in order to provide excellent care for arthroplasty patients. In addition, Dr. Sigmund is actively involved in HSS committees and work groups shaping policies around medical care and management of arthroplasty patients to ensure the best possible outcome for patients.

Research Interests

As Director of the Arthroplasty Service at the Hospital for Special Surgery, Dr. Sigmund is continually presented with clinical scenarios that serve as the basis for her published research. Whether it's understanding if a patient really needs a certain test before a procedure, or a patient has an elevated heart rate after a procedure, the daily dilemmas of perioperative care naturally point towards avenues of research that are of a high clinical importance in orthopedic surgery.

In her role as a medical director for an orthopedic surgical service, she can collaborate effectively with surgical colleagues to address clinical issues relevant to the orthopedic patient. For example, through collaboration with colleagues in her own department as well as the Department of Orthopedic Surgery, she published a project to the Journal of Arthroplasty examining the role of End Tidal CO2 in assessing patients for pulmonary embolism in the postoperative period.

Dr. Sigmund also recently collaborated with colleagues in the Department of Population Health and the Department of Anesthesia to complete "Use of Preoperative Testing and Physician Response to Professional Society Guidance," examining national trends in the use of preoperative testing, which was then published in JAMA Internal Medicine.

She is now collaborating with colleagues in orthopedic surgery and rheumatology to address the best way to identify who may have a pulmonary embolus after surgery.
