Some patients take 2nd at-home fecal test to delay colonoscopy

A study of 316,443 patients shows that 7.4% of patients repeated fecal testing rather than proceeding directly to colonoscopy as guidelines recommend, and of those who repeated home tests, over half did not have a colonoscopy within one year. Colorectal cancer is the second most common cancer-related cause of death in the United States, but ...

Study suggests waning protection from Moderna bivalent COVID-19 vaccine

Emerging COVID-19 variants continue to cause serious COVID-19 disease, but most people have not received any COVID-19 vaccine for more than a year.

Featured Division

Biostatistics Research

Our biostatisticians provide expert guidance on working with real-world clinical data to investigators in all of our scientific divisions.

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.
