John Muir Health

John Muir Health is a hospital network headquartered in Walnut Creek, California and serving Contra Costa County, California and surrounding communities (all considered suburbs of Oakland and San Francisco). It was formed in 1997 from the merger of John Muir Medical Center (based in Walnut Creek) and Mount Diablo Medical Center (based in neighboring Concord).
John Muir Health includes two of the largest medical centers in Contra Costa County: John Muir Medical Center, Walnut Creek, a medical center that serves as Contra Costa County's only designated trauma center; and John Muir Medical Center, Concord. Together, they are recognized as preeminent centers for neurosciences, orthopedics, cancer care, cardiovascular care and high-risk obstetrics. Other areas of specialty include general surgery, robotic surgery, weight loss surgery, rehabilitation and critical care. Both hospitals are accredited by The Joint Commission, a national surveyor of quality patient care.
John Muir Health also offers complete inpatient and outpatient behavioral health programs and services at its Behavioral Health Center, a fully accredited, 73-bed psychiatric hospital located in Concord.
Since its inception in 1996, the John Muir Physician Network has become one of the largest physician networks in Northern California, with more than 900 primary care and specialty physicians. Physicians associated with the Physician Network belong to either John Muir Medical Group (JMMG) or Muir Medical Group IPA, Inc. The Physician Network owns and operates primary care practices staffed by JMMG physicians in 23 locations from Brentwood to Pleasanton. 
In addition, John Muir Health provides outpatient services throughout the community and urgent care centers in Brentwood, Concord, San Ramon and Walnut Creek.

History.
The John Muir Medical Center in Walnut Creek opened in 1965 after the efforts of several local doctors, who received financing in part from a Hill–Burton Act grant. 
Concord Hospital was established in 1930, in a modest one-story home at 2334 Almond Avenue (which exists to this day and is used as a private residence). Concord Hospital was founded by Edna Haywood, a nurse; the facility would expand into a two-story hospital. In 1972, further expansion led to the creation and construction of Mount Diablo Hospital/Medical Center.
In 1997, John Muir Medical Center merged with Mt. Diablo Medical Center, based in neighboring Concord, to form the John Muir/Mt. Diablo Health Network. Because Mt. Diablo was a publicly-run facility, residents of the Mt. Diablo service area needed to approve the merger by popular vote, which they did in 1996. In 2005, the system adopted its current name to further define itself as one common healthcare system.
On January 13, 2022 John Muir Health was sued by Dr. Alicia Kalamas who alleged that institutional failures led to the death of a child and several adult patients. She alleged that profit motives interfered with patient care decisions. The hospital denied wrongdoing and stated that patient safety was a top priority. 
On April 7, 2022 the San Francisco Chronicle ran an 8 ½ page article exposing how John Muir’s Walnut Creek hospital performed a complex surgery on a child, Ailee Jong despite being warned that they lacked the ability to safely perform the surgery.  The article detailed how John Muir entered into a branding arrangement with Stanford Health but actually lacked the skills offered at Stanford’s facilities.  The parents then chose John Muir thinking they were obtaining the same care as they would have received at Stanford.  The child died on the operating table.
John Muir responded to the article stating that the surgery was properly performed and that the child was frail and could have died even under optimal circumstances.  On April 15, 2022 the Medical Board of California launched an investigation of John Muir and its doctors relating to the death of Ailee Jong.
