Kaiser Permanente improves emergency care for chest-pain patients

Emergency physicians at Kaiser Permanente hospitals in Southern California reduced hospital admissions and cardiac stress testing by using new criteria to assess the level of risk patients with chest pain have for subsequent cardiac events. The emergency department assessment was implemented across Kaiser Permanente Southern California and has improved the quality and efficiency of care ...

Kaiser Permanente co-hosts embedded research conference

Organizations like Kaiser Permanente can make continuous improvements in the quality, safety, and value of patient care and at the same time contribute to scientific knowledge nationally and internationally by embedding researchers in their health care systems. This week, leaders in the movement toward learning health care systems will meet in Pasadena, Calif. to create ...

Flu vaccine is safe for hospitalized patients

Hospitalized patients who received the flu vaccine had no increased risk of outpatient visits or hospital readmission within seven days of discharge, according to a Kaiser Permanente study published in Mayo Clinic Proceedings. The study also showed that vaccinating hospital patients did not increase the risk of fever or rates of laboratory evaluations for infection. ...

How low is too low? Study highlights serious risks for intensive blood pressure control

Kaiser Permanente research published today in the American Journal of Preventive Medicine found if patients with hypertension taking prescribed medications experience unusually low blood pressures — systolic blood pressure under 110mmHg — they are twice as likely to experience a fall or faint as patients whose treated blood pressure remains 110mmHg and above. This research ...


Upcoming conference

Details on the conference and registration information will be released in early May. Please check the meeting webpage for updates on key dates and deadlines.

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.
