IntroductionChildren become ill quite often, mainly because of infections, most of which can be managed in the community. Many children are prescribed antibiotics which contributes to antimicrobial resistance and reinforces health-seeking behaviour. Point-of-care C reactive protein (POC CRP) testing, prescription guidance and safety-netting advice can help safely reduce antibiotic prescribing to acutely ill children in ambulatory care as well as save costs at a systems level.Methods and analysisThe ARON (Antibiotic prescribing Rate after Optimal Near-patient testing in acutely ill children in ambulatory care) trial is a pragmatic cluster randomized controlled superiority trial with a nested process evaluation and will assess the clinical and cost effectiveness of a diagnostic algorithm, which includes a standardised clinical assessment, a POC CRP test, and safety-netting advice, in acutely ill children aged 6 months to 12 years presenting to ambulatory care. The primary outcome is antibiotic prescribing at the index consultation; secondary outcomes include clinical recovery, reconsultation, referral/admission to hospital, additional testing, mortality and patient satisfaction. We aim to recruit a total sample size of 6111 patients. All outcomes will be analysed according to the intent-to-treat approach. We will use a mixed-effect logistic regression analysis to account for the clustering at practice level.Ethics and disseminationThe study will be conducted in compliance with the principles of the Declaration of Helsinki (current version), the principles of Good Clinical Practice and in accordance with all applicable regulatory requirements. Ethics approval for this study was obtained on 10 November 2020 from the Ethics Committee Research of University Hospitals Leuven under reference S62005. We will ensure that the findings of the study will be disseminated to relevant stakeholders other than the scientific world including the public, healthcare providers and policy-makers. The process evaluation that is part of this trial may provide a basis for an implementation strategy. If our intervention proves to be clinically and cost-effective, it will be essential to educate physicians about introducing the diagnostic algorithm including POC CRP testing and safety-netting advice in their daily practice.Trial registration numberClinicalTrials.gov Identifier: NCT04470518.

ObjectiveThe aim of this review was to collate all available evidence on the impact of point-of-care C reactive protein (CRP) testing on patient-relevant outcomes in children and adults in ambulatory care.DesignThis was a systematic review to identify controlled studies assessing the impact of point-of-care CRP in patients presenting to ambulatory care services. Ovid Medline, Embase, Cochrane Database of Systematic Reviews, Cochrane CENTRAL, DARE, Science Citation Index were searched from inception to March 2017.Eligibility criteria for selecting studiesControlled studies assessing the impact of point-of-care CRP in patients presenting to ambulatory care services, measuring a change in clinical care, including but not limited to antibiotic prescribing rate, reconsultation, clinical recovery, patient satisfaction, referral and additional tests. No language restrictions were applied.Data extractionData were extracted on setting, date of study, a description of the intervention and control group, patient characteristics and results. Methodological quality of selected studies and assessment of potential bias was assessed independently by two authors using the Cochrane Risk of Bias tool.Results11 randomised controlled trials and 8 non-randomised controlled studies met the inclusion criteria, reporting on 16 064 patients. All included studies had a high risk of performance and selection bias. Compared with usual care, point-of-care CRP reduces immediate antibiotic prescribing (pooled risk ratio 0.81; 95% CI 0.71 to 0.92), however, at considerable heterogeneity (I2=72%). This effect increased when guidance on antibiotic prescribing relative to the CRP level was provided (risk ratios of 0.68; 95% CI 0.63 to 0.74 in adults and 0.56; 95% CI 0.33 to 0.95 in children). We found no significant effect of point-of-care CRP testing on patient satisfaction, clinical recovery, reconsultation, further testing and hospital admission.ConclusionsPerforming a point-of-care CRP test in ambulatory care accompanied by clinical guidance on interpretation reduces the immediate antibiotic prescribing in both adults and children. As yet, available evidence does not suggest an effect on other patient outcomes or healthcare processes.PROSPERO registration numberCRD42016035426; Results.

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).

C reactive protein (CRP), a marker for the presence of an inflammatory process, is the most extensively studied marker for distinguishing bacterial from non-bacterial infections in febrile patients. A point-of-care test for bacterial infections would be of particular use in low-resource settings where other laboratory diagnostics are not always available, antimicrobial resistance rates are high and bacterial infections such as pneumonia are a leading cause of death. This document summarises evidence on CRP testing for bacterial infections in low-income and middle-income countries (LMICs). With a push for universal health coverage and prevention of antimicrobial resistance, it is important to understand if CRP might be able to do the job. The use of CRP polarised the global health community and the aim of this document is to summarise the ‘good and the bad’ of CRP in multiple settings in LMICs. In brief, the literature that was reviewed suggests that CRP testing may be beneficial in low-resource settings to improve rational antibiotic use for febrile patients, but the positive predictive value is insufficient to allow it to be used alone as a single tool. CRP testing may be best used as part of a panel of diagnostic tests and algorithms. Further studies in low-resource settings, particularly with regard to impact on antibiotic prescribing and cost-effectiveness of CRP testing, are warranted.

Objectives We conducted a qualitative process evaluation embedded in a cluster randomized controlled trial in rural Guangxi China, which successfully reduced antibiotic use for children upper respiratory tract infections. This study aims to report on the factors that influenced behaviour change among providers and caregivers in the intervention arm, and to explore contextual considerations which may have influenced trial outcomes. Methods A total of 35 in-depth interviews were carried out with hospital directors, doctors, and caregivers of children. Participants were recruited from six purposively selected facilities, including two higher performing and two lower performing facilities per trial results. Interviews were conducted in Chinese and translated to English. We also observed guideline training sessions and prescription peer review meetings. Data were analysed using framework analysis. Results Intervention-arm doctors described that training sessions improved their knowledge, skills and confidence in appropriate prescribing. This was contrasted by control arm participants who did not receive training and reported less agency in reducing prescribing rates. Prescription peer review meetings were seen as an opportunity for further education, action planning and goal setting, particularly in high performing hospitals, where these meetings were led by senior doctors who were perceived to have relevant clinical experience. Caregiver participants reported that intervention educational materials were helpful but they identified information from doctors was more useful. Providers and caregivers also described contextual health system factors, including hospital competition, short consultation times, and antibiotic availability without prescription, which shaped care preferences. Conclusions This qualitative process evaluation identified a range of factors that may have influenced behaviour among providers and caregivers leading to observed changes in reducing inappropriate antibiotic prescribing in China. Future interventions to reduce antibiotic prescribing should consider system level and wider contextual factors to better understand behaviours and patient care preferences.

BackgroundOveruse of antimicrobials and the threats posed by resistance are concerning. Most patients in primary care with respiratory tract symptoms are prescribed antibiotics, amounting between 80–90% of all prescriptions. The National Institute for Health and Care Excellence (NICE) recommends point-of-care (POC) testing of C-reactive protein (CRP) where there is uncertainty about prescribing antibiotics. Studies evaluating the use of POC CRP to reduce antibiotic prescribing for self-limiting respiratory illness in primary care have demonstrated heterogeneity in their results.AimTo evaluate the impact of POC CRP testing on antibiotic prescribing.MethodA retrospective case analysis was undertaken at a GP practice. Alere Afinion AS100 was used for POC CRP testing. Data were collected on patients presenting with cough or sore throat who had POC CRP testing used in their clinical decision making. Eighty-four cases were selected for inclusion. NICE clinical guideline CG191 was used as a standard comparator for antibiotic prescribing and patients were followed up over a 2-month period.ResultsPatients presented with cough (n = 56) and sore throat (n = 28). At initial presentation 23/84 (27.4%) of patients were prescribed antibiotics. Over the 2-month follow-up period 15/84 (17.8%) of patients had at least one further consultation related to their initial respiratory complaint with 6/84 (7.1%) being prescribed antibiotics. The overall effect was a reduction of antibiotic prescriptions by 65.5%.ConclusionThe use of POC CRP testing helped GPs reduce the rate of antibiotic prescription and improve antimicrobial stewardship by being an addition to their diagnostic armoury. It has also shown potential role in patient reassurance and modifying health seeking behaviour.
