Evidence for using point-of-care diagnostics in the management of respiratory tract infections in primary care: a scoping review protocol [version 1; peer review: 2 approved]
Abstract
Background: Antimicrobial resistance (AmR) is widely considered a global health threat and is associated with significant morbidity, mortality and costs. Inappropriate antimicrobial use is the most important modifiable risk factor for AmR. Most human antimicrobial medicines use occurs in primary care [prescribed by general practitioners (GPs), dispensed by community pharmacists (CPs)]. However, up to 50% of use is deemed inappropriate. Point-of-care diagnostic tests are used as a basis for antimicrobial stewardship interventions to improve the diagnostic certainty of respiratory tract infections (RTIs), and therefore ensure prudent antimicrobial use. However, there is a lack of guidance on their use, and they are therefore not routinely used in clinical practice. Objective: A scoping review will be conducted to synthesise the available evidence to inform the development of best practice guidance for using point-of-care diagnostics in the management of RTIs in primary care. Methods: A scoping review will be conducted following guidance from the Joanna Briggs Institute (JBI) and reported using the PRISMA-ScR guidelines. Databases including Web of Science, MEDLINE, CINAHL, EMBASE, the International HTA database and the Cochrane Central Register of Controlled Trials, as well as grey literature, will be searched. Screening will be undertaken independently by two reviewers to identify studies and literature reporting the use of point-of-care diagnostics in the management of RTIs in primary care by GPs and/ or CPs. Findings will be described using narrative synthesis. Conclusion: The findings of this scoping review will be used to produce draft guidance on the use of point-of-care diagnostic tests in primary care, which will undergo further development using a Delphi consensus methodology involving experts in the field of RTIs, antimicrobial stewardship, point-of-care diagnostics and primary care.
