Providence Health & Services has agreed to buy Tarzana (CA) Regional Medical Center from Tenet Healthcare Corp. for an undisclosed price. In 2004, Tenet disclosed that it intended to sell the medical center, but the chain had difficulty getting the real estate investment trust that owns the Tarzana building and campus to agree on the terms of a sale. Some doctors and medical staff have complained that Tenet failed to invest adequately in the hospital as it tried to sell the facility.
