Kaiser Permanente operates a clinic in Pleasanton and has other clinics and medical centers in Northern and Southern California.
The medical group also received four stars in the "Patients Rate their HMO" category, which measures members' satisfaction with their care and service.
The 2014 report card (http://www.opa.ca.gov/report_card/) provides California consumers with side-by-side comparisons of the largest health plans in the state. It ranks the health plans on national standard-of-care measures that involve treatment and prevention of a range of conditions that have significant implications for personal health.
Of the 10 HMOs and six PPOs compared in the report card, Kaiser Permanente alone had the top rating for overall clinical-care measures.
"Kaiser Permanente Northern California is transforming health care with its integrated care model, a system in which each member's team of care providers works in concert to ensure the best possible care and outcomes," said Gregory A. Adams, group and regional president of Kaiser Foundation Hospitals/Health Plan Inc., in Northern California.
"We also understand that good health extends beyond the doctor's office and the hospital," he added. "For more than 60 years, we have been committed to helping people lead healthy lives and improving the health of the communities we serve."
This year, Kaiser Permanente in Northern California earned four stars in eight of the nine report-card categories for clinical care, including asthma and lung care, cancer screening, diabetes care, heart care, maternity care and "getting the right care" for both adults and children.
"Today, Kaiser Permanente is the leader in quality and service and a model for health care in this country," said Dr. Robert Pearl, executive director and CEO of the Permanente Medical Group.
"By attracting the best physicians and providing them with cutting edge technology, our patients receive the best and most convenient care possible," he added. "As health-care reform shifts the emphasis from quantity of care to quality of care, Permanente medicine is the model that physician groups across the nation are increasingly trying to emulate."
Since 2012, the National Committee for Quality Assurance, the premier organization measuring the performance of health-care providers in the U.S., has been a partner with the OPA in developing the annual report card in California.
