The Integrated Delivery System (IDS), is comprised of 140 physician members, was established in 1997 as an Independent Practice Association (IPA) and was one of the first community oriented physician/hospital IPAs to address the lack of adequate Medicare Managed Care services in Chautauqua County. In partnership with Univera Healthcare, the IDS has addressed that need.
