Advocate Health Care, Illinois’s largest health system,  will  buy  56 healthcare clinics that it will operate  in Walgreens drugstores  in metropolitan Chicago, The clinics will be renamed Advocate Clinics at Walgreens and open under Advocate in May.

Walgreens said that the move is part of its strategy to create “more innovative approaches with health systems.”

Walgreens  seems to have a strategy of pulling back from running clinics in its drugstores and instead turning to hospital systems. Just last year, Seattle-based Providence Health & Services, the third largest not-for profit health system in the United States, said it  would open 25 new retail clinics in Walgreens drugstores in Oregon and Washington.
