Official title: Point of Care Testing Using FebriDx to Improve Antibiotic Use for Respiratory Tract Infections in Primary Care: a Mixed Methods Feasibility Study

Status Not yet recruiting

Clinical Trial Summary

This is a mixed-methods, multi-centre feasibility study. Formal advice and peer-review with regards to study design was sought from the Southampton Research Design Service (RDS), the NIHR CRN Wessex, and patient contributors during the development of the grant application. We will recruit up to ten GP practices, each given 20-40 FebriDx tests (300 in total). Up to four clinicians per practice will be trained to use the test. A sequential explanatory approach to data collection will be taken (21), with quantitative data analysis in stage one, followed by qualitative interviews with the study's practice participants in stage two.

Clinical Trial Description

It can be difficult to tell the difference between viral and bacterial infections. Many patients are therefore prescribed antibiotics unnecessarily. Overuse of antibiotics is leading to a crisis of 'antibiotic resistance', where antibiotics no longer work for some infections.

FebriDx ® is a new hand-held test that uses a 'finger-prick' of blood, and within 10 minutes, provides a result that can help clinicians decide whether an infection is likely to be caused by a virus or bacteria. This could help clinicians decide when antibiotics are needed, but the test has not been adequately tested in primary care.

We would like to do a future study to test whether FebriDx can safely reduce antibiotic prescriptions in primary care.

However, before we do this, we need to do a smaller 'feasibility' study to explore how easy to use the FebriDx test is and, what GPs and patients think of the test, and to help us design a larger future study.

Aims

1. Explore whether FebriDx could reduce the use of antibiotics for chest infections in primary care.

2. Explore how feasible it would be to do a large research study in the future using FebriDx

Methods

We will recruit up to ten GP practices, each given 20-40 FebriDx tests (300 total).

Stage one Patients with a chest infection will be invited to participate if their clinician has decided that they are likely to prescribe antibiotics. Following consent, the clinician will record some basic information about the patient, and the patient will undergo the FebriDx test. The clinician will then record whether or not they prescribed antibiotics and if they think the test had an effect on their decision. Patients will also undergo an optional nasopharyngeal swab.

Stage two Clinicians and patients will be interviewed on how useful they think FebriDx testing is, and how they think we should design a larger future study. ;
