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.
Despite a broad campaign among physician groups to reduce the amount of imaging in medicine, the rates of use of CT, MRI and other scans have continued to increase in both the United States and Ontario, Canada, according to a new study of more than 135 million imaging exams.
A study in Annals of Surgical Oncology finds that the rate of home recovery after mastectomy increased from 23% regionwide to 61% in the 6 months after the program started, with no significant changes in emergency-department visits, reoperations, or readmissions.
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.
Coinciding with Colon Cancer Awareness Month (March), Kaiser Permanente Northern California received the National Colorectal Cancer Roundtable’s prestigious “80% by 2018” National Achievement Award, in recognition of screening rates over 83 percent for colorectal cancer.
Does weight gain — or loss — change a breast cancer patient's cancer outcome? What about muscle mass? Epidemiologist Bette Caan wanted to find out about that, and more.
The JAMA Network, the publication home for numerous top-tier journals from the American Medical Association, released a list of the “Most Talked About Articles” in each of their various publications for 2018. DOR research appears on four lists.
Ten years after a negative colonoscopy, Kaiser Permanente members had 46 percent lower risk of being diagnosed with and were 88 percent less likely to die from colorectal cancer compared with those who did not undergo colorectal cancer screening.
Building on years of collaboration, a doctor crosses the San Francisco Bay to continue his work on colorectal cancer prevention with the research team of his mentor.
