Beyond the initial collaborative, the RWJF has expanded TCAB in several ways. It funded a sixty-seven-hospital collaborative conducted by the American Organization of Nurse Executives (AONE); it created a Web site that provides information to hospitals seeking to implement TCAB independently; and it has incorporated TCAB as a component of its Aligning Forces for Quality initiative. The IHI supports a TCAB Learning and Innovation community with eighty-one hospitals in its IMPACT Network; the program has spread to hospitals in four countries. Hospitals not formally participating in any collaborative have implemented TCAB-like programs by drawing on published descriptions and contact with TCAB hospitals. Hospitals provided a variety of resources to facilitate the work of front-line staff, including release time for nurses to conduct TCAB work, training in quality improvement methods, travel to collaborative meetings, and participation by resource personnel such as nurse educators, clinical nurse leaders, and quality improvement staff.
