Research showing value of exercise before COVID-19 diagnosis earns special recognition

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.

Study evaluates heart disease risk prediction across Asian ethnicities

A Kaiser Permanente study found that the PREVENT cardiovascular risk equation had strong overall ability to predict 10-year cardiovascular disease risk in Asian, Native Hawaiian, and Other Pacific Islander adults. However, its accuracy differed across specific Asian ethnic subgroups and showed consistent patterns of over- and under-estimating when grouping by race and ethnicity. The study ...

Rethinking MS treatment: Why less may be more

For years, people living with relapsing forms of multiple sclerosis (MS) have depended on powerful medications to keep their disease under control. One of the most effective treatments has been rituximab, a therapy that works by depleting B cells, which are the immune cells that drive inflammation with MS. However, new research from Kaiser Permanente ...

Staying active during pregnancy helps keep postpartum weight off

For years, researchers have known that many people struggle to lose the weight they gain during pregnancy. Up to 1 in 4 individuals retain at least 10 pounds 1 to 2 years after giving birth, and this lingering weight can raise their long‑term risk of hypertension, cardiovascular disease, and other metabolic problems. Despite the importance ...

Wildfire smoke studies reveal differing health risks

Wildfire smoke has increasingly been recognized as a serious public health threat. Now, 2 new Kaiser Permanente studies in Southern California have examined how health risks for both young and old people might be associated with exposure. One study showed that long-term exposure increased the risk of death among older adults, while another found that ...

Health Services Research & Implementation Science

Our health services researchers bring together scientific and clinical expertise to find better ways to improve care.

Investigators with the Division of Health Services Research & Implementation Science study how care is delivered, identify opportunities for care improvement, and implement new approaches for organizing and delivering health services. The division brings together scientists with diverse expertise and training, including emergency medicine, epidemiology, health services research, implementation science, internal medicine, nursing, pharmaceutical economics, and pulmonology.

The division co-leads the Care Improvement Research Team, a research team embedded within Kaiser Permanente Southern California’s quality improvement ecosystem. The team works closely with clinical and operational partners at Kaiser Permanente Southern California to identify, prioritize, and solve problems related to quality and affordability. Its goal is to reduce unnecessary practice variation, improve affordability, and transform care.
