Sidney Garfield

As the war came to an end, the Bay Area shipyards were rapidly scaled back and closed. The health plan membership shrank precipitously. The caregiving staff was correspondingly reduced. At its nadir as few as a dozen medical doctors remained in the organization. New postwar industries, however, hired workers needing health care. New health plan participants were recruited and expanded to include workers' families as well. Garfield was instrumental in managing this dramatic transformation. He continued in this position into the late 1950s. By 1990, Kaiser Permanente was the country's largest nonprofit HMO.

By August 1944, 92.2 percent of all Richmond shipyard employees had joined the plan, the first voluntary group plan in the country to feature group medical practice, prepayment and substantial medical facilities on a large scale.

In part due to wartime materials rationing, Garfield's original field hospital was a single-story wood frame structure designed in a simple modernist mode. Intended for use primarily as an emergency facility, it opened with only 10 beds. Later additions increased its capacity to 160 beds by 1944. The Field Hospital operated as a Kaiser Permanente hospital until closing in 1995.

The Kaiser Richmond Field Hospital for the Kaiser Shipyards, financed by the United States Maritime Commission, opened on August 10, 1942. It was sponsored by Henry J. Kaiser's Permanente Foundation and Garfield was the Medical Director. The field hospital served as the mid-level component of a three-tier medical care system that also included six well-equipped first aid stations at the individual shipyards, and the main Kaiser Permanente hospital in Oakland, California, where the most critical cases were treated. Together, these facilities served the employees of the Kaiser shipyards who had signed up for the Permanente Health Plan (commonly referred to as the "Kaiser Plan"), one of the country's first voluntary pre-paid medical plans, and a direct precursor to the Health Maintenance Organizations (HMOs) defined by the federal Health Maintenance Organization Act of 1973.

In 1933, Garfield opened his 6-bed Contractor's General Hospital in the Mojave Desert, east of Los Angeles, California, north of Desert Center. At the time of its construction and use, it was the only air-conditioned building between Los Angeles and Phoenix. This hospital was set up to provide medical care for the 5,000 workers on the Metropolitan Water District of Southern California's aqueduct, which was designed to bring water from the Colorado River to Los Angeles.

Sidney R. Garfield (April 17, 1906 – December 29, 1984) was an American medical doctor and a pioneer of health maintenance organizations. He co-founded the Kaiser Permanente healthcare system with businessman Henry J. Kaiser. He graduated from the University of Iowa College of Medicine in 1928, which is now called the Roy J. and Lucille A. Carver College of Medicine.
