Additional file 2. Interview guide: Post-implementation telephone interviews. This interview guide was developed from the CFIR constructs and definitions of Damschroder et al., 2009 [26] and the interview guide tools that became available on the CFIR website at the post-implementation phase of the study. See https://cfirguide.org/ and http://cfirwiki.net/guide/app/index.html#/guide_select . Given the brief telephone interview format, selected questions from each domain were included based on findings of the process evaluation to that point.
