About Dr. Patricia A. Brock
Dr. Patricia Brock is Professor in the Department of Emergency Medicine at MD Anderson Cancer Center (MDACC) serving as Deputy Chair and Executive Medical Director of Inpatient Operations. Dr. Brock is noted for her commitment to the emerging field of oncologic emergency medicine. She founded and co-chairs the annual Oncologic Emergency Medicine Conference and helped develop the first Oncologic Emergency Medicine Fellowship Program. Dr. Brock graduated from The University of Louisville School of Medicine, began her surgical training at Parkland Hospital in Dallas at The University of Texas program, and completed her surgical residency at the San Antonio’s UT Health Sciences Center. After a 10-year career as a general surgeon, Dr. Brock turned her energies to raising her growing family of four. During this short hiatus she founded an international non-profit, Medical Bridges, which has shipped $110 million USD of medical supplies and equipment globally over the past 26 years. Dr. Brock returned to the practice of medicine at Baylor College of Medicine’s Emergency Department and transitioned to MD Anderson 13 years ago. During her time at MDACC she has gained a reputation as a collaborator and an analytical person leading efforts to improve patient throughput within her department and now within the hospital. She championed the effort to incorporate Observation services into the responsibility of the Emergency Medicine Department in 2019. Her clinical research activity has included HIV testing in the Emergency Department, delirium, as well as the integration of palliative care in the emergency department. She is currently studying the effects of boarding time on cancer patient’s mortality and analyzing new patient demographics on those who seek to establish care via the emergency department. Within the local community Dr. Brock continues her global health interest working with Medical Bridges and Houston Global Health Collaborative, a TMC non-profit interfacing faculty, students and trainees from multiple healthcare backgrounds who are interested in global health.
