Dr. Law is a Pulmonary and Critical Care physician, clinical epidemiologist, and health services researcher with a focus improving outcomes of critically ill patients. Her research leverages large clinical and administrative databases to characterize external (e.g. legislation), internal (e.g. hospital and provider), and patient drivers of practice pattern variation, and determines how practice pattern variations (especially related to the placement of tracheostomy and gastrostomy tubes during acute critical illness, and the use use of post-acute care facilities after acute critical illness) affect long-term outcomes of the critically ill.
