Figure 1. Development timeline of the NHSN Hemovigilance Module.

Figure 1

The concept for the Hemovigilance Module was introduced in 2006 with development beginning in 2007 in collaboration with expert groups convened by AABB. In 2009, the module was piloted in 9 facilities, and national enrollment began in January 2010. In 2011, the total number of facilities that enrolled in the module reached 100. The first progress reports were presented in 2012. In 2013, in an effort to increase participation, the protocol was simplified such that near-miss and no-harm incidents were no longer required.
