C-reactive protein (CRP) point-of-care testing (POCT) is increasingly being promoted to reduce diagnostic uncertainty and enhance antibiotic stewardship. In primary care, respiratory tract infections (RTIs) are the most common reason for inappropriate antibiotic prescribing, which is a major driver for antibiotic resistance. We systematically reviewed the available evidence on the impact of CRP-POCT on antibiotic prescribing for RTIs in primary care. Thirteen moderate to high-quality studies comprising 9844 participants met our inclusion criteria. Meta-analyses showed that CRP-POCT significantly reduced immediate antibiotic prescribing at the index consultation compared with usual care (RR 0.79, 95%CI 0.70 to 0.90, p = 0.0003, I2 = 76%) but not during 28-day (n = 7) follow-up. The immediate effect was sustained at 12 months (n = 1). In children, CRP-POCT reduced antibiotic prescribing when CRP (cut-off) guidance was provided (n = 2). Meta-analyses showed significantly higher rates of re-consultation within 30 days (n = 8, 1 significant). Clinical recovery, resolution of symptoms, and hospital admissions were not significantly different between CRP-POCT and usual care. CRP-POCT can reduce immediate antibiotic prescribing for RTIs in primary care (number needed to (NNT) for benefit = 8) at the expense of increased re-consultations (NNT for harm = 27). The increase in re-consultations and longer-term effects of CRP-POCT need further evaluation. Overall, the benefits of CRP-POCT outweigh the potential harms (NNTnet = 11).

Antimicrobial resistance (AMR) continues to be a global problem and continues to be addressed through national strategies to improve diagnostics, develop new antimicrobials and promote antimicrobial stewardship. Patients who attend general (ambulatory) practice with symptoms of respiratory tract infections (RTIs) are invariably assessed by some sort of clinical decision rule (CDR). However, CDRs rely on a cluster of non-specific clinical observations. A narrative review of the literature was undertaken to ascertain the value of C reactive protein (CRP) point-of-care testing (POCT) to guide antibacterial prescribing in adult patients presenting to general practitioner (GP) practices with symptoms of RTI. Studies that were included were Cochrane reviews, systematic reviews, randomised controlled trials, cluster randomised trials, controlled before and after studies, cohort studies and economic evaluations. An overwhelming number of studies demonstrated that the use of CRP tests in patients presenting with RTI symptoms reduces index antibacterial prescribing. GPs and patients report a good acceptability for a CRP POCT and economic evaluations show cost-effectiveness of CRP POCT over existing RTI management in primary care. POCTs increase diagnostic precision for GPs in the better management of patients with RTI. With the rapid development of artificial intelligence, patients will expect greater precision in diagnosing and managing their illnesses. Adopting systems that markedly reduce antibiotic consumption is a no-brainer for governments that are struggling to address the rise in AMR.

Abstract Background Approximately 60% of antibiotics issued in primary care are for acute respiratory tract infections (RTIs), which are largely self-limiting and do not require antibiotics. Point-of-care testing (POCT) devices that measure C-reactive protein (CRP)—a biomarker for infection—can be used to guide prescribing decisions. Objective We evaluated the cost-effectiveness and budget impact of a national CRP POCT program to guide antibiotic prescribing for acute RTIs in primary care in Ireland. Methods We compared CRP POCT with and without enhanced communication skills training of general practitioners against usual care. A probabilistic decision tree was used to investigate cost-effectiveness from the perspective of the healthcare system. The model considered outcomes for the Irish population over a 5-year time horizon. Inputs were synthesized from published studies. Cost-effectiveness was estimated using an incremental cost per prescription avoided. Results CRP POCT with and without communication training were more costly but more effective than usual care over 5 years. CRP POCT alone was dominated, while the combined intervention had a cost per prescription avoided of €111 (95% CI: €45–243) versus usual care. The budget impact was costly over 5 years, but potential budget savings were available depending on the implementation scenario. The findings were largely robust to sensitivity analyses. Conclusions CRP POCT reduces antibiotic prescribing, but increases healthcare costs. The most cost-effective program of CRP POCT includes enhanced communication skills training. Further research on the impact of CRP POCT beyond 5 years is warranted, as well as the potential impact on antimicrobial resistance.
