Implementation strategy categories identified in the included studies. The interventions in the 49 included studies were coded to the implementation strategy domains (1 to 9) and categories (1 to 73) developed by the Expert Recommendations for Implementing Change (ERIC) program [18, 19]. Each column represents one of the 73 implementation strategy categories. A shaded cell indicates the specific strategy that the intervention under investigation in the study involved. Only the four domains that were identified are displayed in this figure. The other domains were not included in any of the studies: Use of evaluative and iterative strategies (Domain 1), Provide interactive assistance (Domain 2), Adapt and tailor to context (Domain 3), Develop stakeholder inter-relationships (Domain 4), Support clinicians (Domain 6). (Wright, 2018) [71] was excluded from narrative synthesis as it was at critical risk of bias
