Kristen Nordenholz, MD

Associate Professor


Kristen E. Nordenholz, MD, FACEP graduated with honors from medical school at the University of Rochester and completed residency at The Johns Hopkins Hospital, after which she served there as Assistant Chief of Service in Emergency Medicine and faculty. She is a Fellow in the American College of Emergency Physicians (ACEP) and an active member of the Society of Emergency Medicine as well as the International Society of Thrombosis and Haemostasis. Her additional training includes completion of the EMF teaching fellowship with ACEP.

She developed a strong interest in diagnostic emergency ultrasound while directing the Tuba City Indian Medical Center Emergency Department on the Navajo Nation (Indian Health Service) for 5 years.  This diagnostic interest expanded to include work on early disease detection and decision analysis, particularly in the area of venous thromboembolism (VTE), with the use of diagnostic markers, clinical protocols and aggressive risk stratification.  She moved from the faculty at The Johns Hopkins Hospital to join the University of Colorado School of Medicine faculty in 2001.  She now spends most of her time teaching and mentoring medical students, interns, residents and other physicians, caring for patients, and performing and presenting clinical research on the use of clinical decision rules, diagnostic markers, and bedside ultrasound. This work has led to decision algorithms in the electronic medical record for deep venous thrombosis and pulmonary embolism in Emergency Medicine. She is active on numerous committees in both the hospital and the SOM, focused predominantly on the use of clinical decision rules to improve patient care. Most recently she has been studying clinical pathways for select VTE patients to receive outpatient management and is site primary investigator for a national randomized control trial of thrombolytic therapy for acute submassive pulmonary embolism.
