Cedars of Lebanon Hospital

Kaspare Cohn Hospital was founded in 1902, named for its major donor, a Jewish businessman^[11] who later founded the bank that became Union Bank & Trust Company^[12] and is now part of U.S. Bancorp.^[13] The hospital's first superintendent, Sarah Vasen, was a graduate of the University of Iowa Medical School who had been the superintendent and obstetrician for the Jewish Maternity Home in Philadelphia.^[14] She was one of Los Angeles’ first women doctors.^[15]

The hospital was intended to serve both the Jewish community and the patients of Jewish doctors, who were denied admitting privileges in other hospitals because of discrimination.^[16]

In 1930, the hospital moved to a new building in Hollywood and changed its name to Cedars of Lebanon Hospital,^[15] after the trees mentioned frequently in Scripture^[17] and reputed to have medicinal properties.^[18]

Mount Sinai Hospital

It was renamed Mount Sinai Hospital in 1926 and moved to a 50-bed facility on Bonnie Beach Place in Los Angeles. In 1955, it moved to Beverly Boulevard, now the location of Cedars-Sinai. ^[15]

Merger of Cedars of Lebanon Hospital and Mount Sinai Hospital

Discussions to merge Cedars of Lebanon and Mount Sinai began in the 1960s. Population growth in Los Angeles, along with the opportunity to expand free care, research and medical education required a larger patient base and expanded facilities.^[19]

The merger process, led by Irving Feintech and Steven Broidy Sr., led to groundbreaking in 1972 for a 1.6-million-square-foot medical center. It received its first patients in 1976.^[15] The new hospital was designed jointly by Albert C. Martin & Associates and Charles Luckman Associates.^[20] The main contractor was Robert E. McKee, Inc.^[21]

The merged hospital retained its Jewish identity, including a mezuzah at the entrance to each room, a kosher kitchen offering meal options to patients and visitors, a sabbath elevator^[22] and a full-time Jewish chaplain.^[15]

The Cedars-Sinai Health System was established in 1994, combining the Medical Center with the Burns and Allen Research Institute, the Cedars-Sinai Medical Foundation and the Physician-Hospital Organization.^[23] The Burns and Allen Research Institute is dedicated on George Burns' 100th birthday two years later in 1996.^[24]

Quaid twins overdose

In 2008, the twin daughters of actor Dennis Quaid were born prematurely and cared for at Cedars. They were accidentally given the wrong version of the blood thinner heparin, which had 1000 times the strength of the version intended.^[54] The twins survived.^[55]

The news was leaked to the website TMZ, which published it^[56] before Quaid's extended family learned of it. The hospital promised an investigation into the leak.^[54]

The California Department of Health Services investigated and cited failures "to adhere to established policies & procedures for safe medication use."^[57] The resulting malpractice claim was settled out of court, and included a commitment by Cedars to introduce electronic record keeping, bedside bar coding and computerized physician-order entry systems to improve patient safety. The hospital also implemented additional procedures for pharmacy and nursing staff.^[58]
