Biography
Dr. John Maa is a surgeon dedicated to improving the quality and access of emergency surgical care. He earned his MD at Harvard Medical School and served as a captain in the medical corps of the U.S. Army for nine years. During medical school, he was awarded the New York City Mayor's Prize for his research thesis entitled "Concomitant Mycobacterium tuberculosis and human immunodeficiency virus infection in New York City, 1986-1991". During a general surgical residency at UCSF, Dr. Maa was awarded a National Institutes of Health Gastrointestinal Research training grant and published numerous scientific articles on pancreatic and gastrointestinal inflammation.
Dr Maa received a patent for his invention of a safer central venous catheter, and is certified by the American Board of Surgery. After completing his residency, Dr. Maa completed a Fellowship in Health Policy at the UCSF Institute of Health Policy Studies, exploring mechanisms to improve the overall structure and processes of general surgical care nationally. During the fellowship, he also assisted in the creation of the UCSF Surgical Hospitalist Program which seeks to enhance the quality and timeliness of hospital based emergency surgical care. Dr Maa's current research focuses on applying the surgical hospitalist model to improve hospital based emergency care, specifically through new processes and strategies that address the challenges of emergency department overcrowding, boarding and ambulance diversion. During the past year, Dr Maa assisted in the creation of a multidisciplinary course in public policy and advocacy for the professional schools of medicine, dentistry, pharmacy and nursing at UCSF.
Dr. Maa is a member of the board of directors of the American Heart Association, and Associate Director of Surgery Clerkship at UCSF. He participates on several advisory boards and committees that focus on improving care in hospitals. Dr. Maa is currently an Assistant Professor in general surgery at the University of California, San Francisco, and Assistant Chair of the Department of Surgery's Quality Improvement Program
