Tri-State Centers for Sight Surgery Center in Cincinnati, Ohio, relies on a transportation service to bring many of its patients to and from the ASC. About 20 percent use the service, says Deborah Bray, RN, the ASC’s director. The service is pivotal to the center’s ability to provide surgical care for its patient population because the Ohio River runs between Cincinnati and Kentucky and some of the affiliated practices of the ASC are in Northern Kentucky.
