Factors influencing implementation of point-of-care testing for acute respiratory infectious diseases in community pharmacies: A scoping review using the Consolidated framework for implementation research

Background Emerging evidence suggests pharmacy-based point-of-care (POC) testing for acute respiratory infections diseases is beneficial, but not widely implemented. A theory-informed review to understand the factors influencing service implementation is lacking. Objective To examine the extent, range, and nature of research available on enablers and barriers to POC testing implementation for infectious respiratory diseases in community pharmacies and identify their underpinning theoretical constructs using the Consolidated Framework for Implementation Research (CFIR). Methods Scoping review guided by the JBI Manual for Evidence Synthesis. A comprehensive search from inception to June 28th, 2022 was conducted using Medline, Embase, CINAHL, Cochrane Library, and ProQuest dissertations without date or language restriction. Eligible articles investigated barriers and/or facilitators to strep throat, influenza, C-reactive protein, and COVID-19 POC testing in community pharmacies. Two reviewers independently performed title & abstract screening, full-text screening, and data extraction. Content analysis was conducted according to a pre-established framework and concepts were mapped to the CFIR. Results Forty-three studies were included. Most originated from the USA (n = 24; 56%) and investigated strep throat. The majority were testing/initial implementation projects (n = 23; 54%) conducted in urban centers (n = 17; 40%). Thirty-six (84%) studies used quantitative methodology, while 6 (14%) were qualitative. Only four studies (9%) used theory to guide their inquiry. The 124 identified implementation factors mapped onto 21 CFIR constructs, covering all 5 domains. The domain “Outer setting” (n = 35/43; 81%) was most prevalent as were the constructs “Patient needs and resources,” (n = 21/43; 49%) “External policy & incentives,” (n = 17/43; 40%) and “Relative advantage” (n = 17/43; 40%). Conclusion A large volume of research explores factors influencing the implementation of pharmacy-based respiratory infectious disease POC testing services, but few studies use qualitative or theory-informed methods. Knowledge of the wide range of facilitators and barriers identified can help pharmacy managers and researchers design strategies to support successful service implementation.
