The original CFIR (Laura J. Damschroder et al. 2009) stated that regardless of how an Inner Setting is structurally organized, the importance of communication across the setting is clear. This construct includes Greenhalgh’s intraorganizational communications (T. Greenhalgh, Robert, et al. 2004). Greenhalgh et al. cite strong or moderate influence of intraorganizational communication on implementation outcomes (T. Greenhalgh, Robert, et al. 2004). Communication failures are involved with the majority of sentinel events in US hospitals – most often between physicians and nurses (P. J. Pronovost et al. 2006). High quality formal communications contribute to effective implementation (Simpson and Dansereau 2007). Strong intra-organizational communications are positively associated with implementation as it pushes decision-making to the front-line teams or individuals (T. Greenhalgh, Robert, et al. 2004; P. W. Meyers, Sivakumar, and Nakata 1999). Making staff feel welcome (good assimilation through communication), peer collaboration, open feedback and review among peers and across hierarchical levels, clear communication of mission and goals, and informal communication quality all contribute to effective implementation (Simpson and Dansereau 2007).
