Casa Bonita Convalescent Hospital holds a 4-star overall rating, in the top tier CMS assigns. Nursing staff turnover of 49% is well above the California average of 37%; high turnover is one of the strongest predictors of inconsistent care. None of this tells you whether a bed is open, whether your insurance is in network, or whether the facility will accept a given level of care — confirm those three directly with the facility before you commit.
