CLEVELAND, Ohio -- The Cleveland Clinic is expanding its reach once again, this time deeper into Northwest Ohio, where it will offer its expertise to the Toledo-based ProMedica health system. ProMedica, which operates 11 hospitals and more than 300 other health care facilities in Northwest Ohio and Southeast Michigan, will collaborate with the Clinic on improving the quality of patient care, reducing costs and making the services and programs it offers more efficient. The two organizations worked out details in a private memorandum of understanding signed earlier this month and announced at midnight Wednesday.
