In 2022, DOR celebrates 60 years of innovative health research.

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. DOR’s 600-plus staff is currently working on more than 580 epidemiological and health services research projects. Read our story on how it all began and in our interactive anniversary timeline.
