About Kaiser Permanente:

In 1945, industrialist Henry J. Kaiser partnered with founding physician Sidney R. Garfield, MD, to open a system of prepaid care to the public in Northern California. Unions viewed the plan as labor-friendly and affordable and formed a huge and welcome membership base in the formative years.

In 1950, Kaiser started the Kaiser Foundation School of Nursing to help fill a nursing shortage following World War II and in 1956, Kaiser Foundation Health Plan, Inc. was established as an independent nonprofit California corporation.

Kaiser established the Kaiser Foundation Harbor Hospital in 1957 which was the first hospital in the country built for members of an employer-sponsored health care plan. It initially provided care to International Longshore and Warehouse Union employees and their families.

In 1976, as health care was changing, Kaiser Permanente’s demonstrated affordability was specifically acknowledged as they were recognized as the best health plan model for the groundbreaking Health Maintenance Organization Act, signed into law in December 1973. Kaiser had turned all of their health plans into qualified HMOs by 1976.

Electronic medical records came to Kaiser in 2003, Kaiser created secure, 24/7 access to up-to-date patient records with no geographic boundaries.

When the pandemic hit in 2020, Kaiser dramatically increased its telehealth system. Virtual care visits rose from about 15% of all visits to about 80%, including more than 30,000 a day via video.
