Rhode Island's largest hospital system, Lifespan, was officially renamed Brown University Health this week. The change comes as part of expanded affiliation agreements and a multi-million dollar annual investment from Brown. The system employs more than 17,000 workers and operates more than 1,620 patient care offices. The planned name change was first announced in June. The University and Brown Health have emphasized that the two organizations will remain independent. 'The name change reflects a deeper alignment between Brown University Health's clinical care and Brown University's academic and research focus,' a university spokesman says.
