St. Rose Becomes an Affiliate of Alameda Health System December 17, 2024 Hot Topics On November 1st, Alameda Health System announced that St. Rose Hospital became an affiliate of Alameda Health System (AHS). This will allow St. Rose to stay open and continue providing care to approximately 400,000 mostly low-income Medi-Cal and Medicare patients in Southern Alameda County. Earlier this year, Governor Newsom vetoed AB2271 which would have forgiven over $17 million in state loans for St. Rose Hospital. ACCMA sent a letter to Governor Newsom urging him to sign the bill. ACCMA members include physicians who practice at St. Rose Hospital and understand the need to keep the only safety-net healthcare provider with emergency and maternity care services in southern Alameda County.
