Factors influencing national implementation of innovations within community pharmacy : a systematic review applying the consolidated framework for implementation research

Background: To meet emergent healthcare needs, innovations need to be implemented into routine clinical practice. Community pharmacy is increasingly considered a setting through which innovations can be implemented to achieve positive service and clinical outcomes. Small-scale pilot programmes often need scaled up nation-wide to affect population level change. This systematic review aims to identify facilitators and barriers to the national implementation of community pharmacy innovations. Methods: A systematic review exploring pharmacy staff perspectives of the barriers and facilitators to implementing innovations at a national level was conducted. The databases Medline, EMBASE, PsycINFO, CINAHL, and Open Grey were searched and supplemented with additional search mechanisms such as Zetoc alerts. Eligible studies underwent quality assessment, and a directed content analysis approach to data extraction was conducted and aligned to the Consolidated Framework for Implementation Research (CFIR) to facilitate narrative synthesis. Results: Thirty-nine studies were included: 16 were qualitative, 21 applied a questionnaire design, and 2 were mixed methods. Overarching thematic areas spanning across the CFIR domains were pharmacy staff engagement (e.g. their positive and negative perceptions), operationalisation of innovations (e.g. insufficient resources and training), and external engagement (e.g. the perceptions of patients and other healthcare professionals, and their relationship with the community pharmacy). Study participants commonly suggested improvements in the training offered, in the engagement strategies adopted, and in the design and quality of innovations. Conclusions: This study's focus on national innovations resulted in high-level recommendations to facilitate the development of successful national implementation strategies. These include (1) more robust piloting of innovations, (2) improved engagement strategies to increase awareness and acceptance of innovations, (3) promoting whole-team involvement within pharmacies to overcome time constraints, and (4) sufficient pre-implementation evaluation to gauge acceptance and appropriateness of innovations within real-world settings. The findings highlight the international challenge of balancing the professional, clinical, and commercial obligations within community pharmacy practice. A preliminary theory of how salient factors influence national implementation in the community pharmacy setting has been developed, with further research necessary to understand how the influence of these factors may differ within varying contexts. Trial registration: A protocol for this systematic review was developed and uploaded onto the PROSPERO international prospective register of systematic reviews database (Registration number: CRD42016038876)
