My body of health services research includes examination of patient risk factors for adverse clinical events such as inpatient mortality, complications, and diagnostic error. I have published in this area and have received multiple grants for my work. This work in many ways was my field’s first systematic attempt in examining unwanted patient events such as complications following congenital heart surgery. This work lead to my being included as part of an international surgical society to help define and create the taxonomy for congenital heart centers to use to track complications in this patient population. I also developed the first taxonomy for categorizing diagnostic errors in the echocardiography assessment of congenital heart disease. This work has lead to multiple successful grant applications and my inclusion in national cardiology societies including the American Society of Echocardiography and the American College of Cardiology working groups in quality to help define quality in diagnostic cardiac imaging for the field.
