“…At the knowledge acquisition (KA) stage, an individual becomes aware that an innovation exists (awareness knowledge), learns what is required to use the innovation (how-to knowledge), and sometimes gathers information related to the underlying principles about how the innovation works (principle knowledge). For health professionals, the knowledge acquisition phase is frequently mediated through journal articles, the posting of new policies or procedures from an authoritative source, and through conference presentations (Fendrick, Hirth, & Chernew, 1996;Landrum, 1998); for consumers, knowledge of medical innovation may be the result of the patient-doctor encounter or information provided by printed materials or the media (Clinkingbeard, Minton, Davis, & McDermott, 1999;Jones, 1999;Newton et al,1998;Marmoreo, Brown, Batty, Cummings, & Powell, 1998).…”
