As a research center embedded within Kaiser Permanente’s large and dynamic health care system, our investigators have a unique opportunity to apply scientific expertise to real-world clinical problems, translate findings into practice, and share what we learn with the broader community.
Dr. Conrad Liang is a vascular and interventional neurologist and lead physician of Neurointerventional Services at the Kaiser Permanente Fontana Medical Center. He is the area research chair for Fontana/San Bernardino on the Southern California Permanente Medical Group’s Regional Research Committee and a physician co-lead of the Kaiser Permanente National Stroke Conference. He is also an assistant professor of Clinical Science at the Kaiser Permanente Bernard J. Tyson School of Medicine and ...
Being active can lower your risk of getting seriously ill with COVID, regardless of your race or the chronic conditions you may have, according to research published last year in the American Journal of Preventive Medicine.
The Kaiser Permanente Southern California findings were important, impactful, and influential. As a result, the journal editors chose the research article, “Associations of Physical Inactivity and COVID-19 Outcomes Among Subgroups,” as the American Journal of Preventive Medicine 2023 Article of the Year.
The benefits of intensive blood pressure shown in the Systolic Blood Pressure Intervention Trial (SPRINT) also helps patients with chronic kidney disease, according to new research led by Kaiser Permanente and Stanford University. The study was published in January 2025 in JAMA Network Open. The SPRINT clinical trial included adults with hypertension and elevated cardiovascular ...
Young people who frequently used electronic media, such as computers, television, and social media, had less physical activity, more stress, and modest cognitive challenges. The study was published in January 2025 in Preventive Medicine. “Our research found an association between electronic media use and a negative impact on youth,” said the study’s lead author, Deborah ...
A recent Kaiser Permanente study described the incidence of IgA nephropathy, an autoimmune kidney disease, nationally, as well as among people of different race and ethnicities. The study was published in the American Journal of Nephrology in November 2024. “IgA nephropathy is a rare disease. Attempts to determine its incidence in the United States have ...
A new study by Kaiser Permanente has shown that the ABRYSVO respiratory syncytial virus vaccine is very effective in reducing emergency room visits and hospital stays due to RSV among older adults. “This Kaiser Permanente research demonstrated the real-world effectiveness of RSV vaccination among those 60 and over,” said lead author Sara Y. Tartof, PhD, ...
Exposure to a specific kind of air pollution, fine particulate matter, during pregnancy may significantly increase the risk of spontaneous preterm birth, which can be dangerous for both the mother and the baby, according to a Kaiser Permanente study published in JAMA Network Open. “Consistent with other study findings, this current study has demonstrated that ...
In our newest edition of IMPACT, we share some of our recent research including one study about the effectiveness of the side-effect monitor our researchers developed during the early days of COVID that has gone onto being used to get feedback on other vaccines. Another study examined issues with chronic kidney disease, and the story reveals how that research has gone onto change practice. Other stories focus on research into air pollution and the risk of preterm birth, younger adults and colon cancer screening outreach, opioid use among breast cancer survivors and the risk of falls, COVID vaccines, and heart failure. We’ve also got 2 Q&As, one with the 2024 physician researcher of the year and one with the director of our Division of Epidemiologic Research.
Investigators with the Division of Biostatistics Research collaborate closely with scientists from the department’s other scientific divisions, as well as physician researchers at medical centers across Kaiser Permanente Southern California. They provide expertise and guidance on study design, power and sample size calculations, data management, data analysis and interpretation, and statistical methodology.
Investigators from the division have expertise in study design and data analysis for observational studies and clinical trials to address study questions. Their expertise spans standard and modern methods that deal with complex and big data for population and causal inferences as well as disease prediction.
Each division has at least one dedicated collaborative biostatistician research scientist assigned to provide statistical guidance on its research studies. In addition, one of the collaborative biostatistician researcher scientists leads the Regional Research Statistical Support team, which supports medical center-based researchers.
