Division of Research Spotlight
The Kaiser Permanente Division of Research conducts, publishes, and disseminates epidemiologic and health services research to improve the health and medical care of Kaiser Permanente members and society at large. We seek to understand the determinants of illness and well-being, and to improve the quality and cost-effectiveness of health care. Currently, DOR’s 550-plus staff is working on more than 350 epidemiological and health services research projects.
David Baer, MD, cofounded the KP Oncology Clinical Trials program in the 1980s.

Body composition, especially excess central adiposity or intra-abdominal fat, can result in an increased risk of cardiovascular disease in normal-weight breast cancer survivors, a large new Kaiser Permanente study shows.
A large, multicenter study of advanced medical imaging in pregnancy, published in JAMA Network Open and co-led by Marilyn Kwan, PhD, found that CT scans were performed in 0.8% of pregnancies in the United States and 0.4% in Ontario in 2016; these rates increased nearly fourfold in the United States and doubled in Ontario over the 21 years.
“This study demonstrates the importance at every BMI level of having more precise measures of muscle and fat to help identify those patients who are at high risk of developing cardiovascular disease,” said co-author Bette J. Caan, DrPH.
