Sandra Dunbar has been a member of the faculty in the Nell Hodgson Woodruff School of Nursing since 1988. She is a cardiovascular nurse researcher and educator whose program of research focuses on psychosocial responses to serious cardiac illness, such as heart failure (HF) and ventricular arrhythmia and treatment with implantable technology. Studies of patient and family responses have led to the development and testing of interventions to improve both physical and psychosocial outcomes. Dunbar's current work is focused on interventions for HF patients who also have diabetes and interventions to improve integrated self care in comorbid conditions. She is also the principal investigator of an NIH funded study focused on caregiver stress for those assisting family members who have heart failure. She has tested a family focused intervention to improve outcomes for patients with chronic heart failure and conducted a clinical trial of a psychoeducational intervention to improve outcomes (depression, anxiety, functional status) of high risk arrhythmia patients treated with an implantable cardioverter defibrillator (ICD).
