C-reactive protein point-of-care testing for lower respiratory tract infections: a qualitative evaluation of experiences by GPs

To explore GPs' attitudes to and experiences of introducing C-reactive protein (CRP) point-of-care testing (POCT) for lower respiratory tract infections (LRTI) in primary care. Semi-structured interview study with 20 GPs who participated in the IMPAC(3)T randomized trial evaluating the effect of GP use of CRP POCT on management of LRTI. Main outcomes were GPs' experiences and views about CRP POCT in general practice, including its role in guiding antibiotic prescribing decisions and applicability and implementation in daily practice. GPs expressed mainly positive attitudes. Test results were rapidly available to support diagnostic and therapeutic processes for LRTI and other common infections, enhancing patient and GP confidence in prescribing decisions and empowering GPs to prescribe antibiotics less often. GPs were concerned about responding to ambiguous test results. They regarded financial reimbursement for using the test as essential for successful uptake. GPs were generally positive about CRP POCT, and they felt that it empowered them to safely prescribe fewer antibiotics for LRTI without alienating their patients. Successful wider implementation should address reimbursement and updating management guidelines to include the place of CRP POCT.

Improving management of patients with acute cough by C-reactive protein point of care testing and communication training (IMPAC3T): study protocol of a cluster randomised controlled trial

BackgroundMost antibiotic prescriptions for acute cough due to lower respiratory tract infections (LRTI) in primary care are not warranted. Diagnostic uncertainty and patient expectations and worries are major drivers of unnecessary antibiotic prescribing. A C-reactive protein (CRP) point of care test may help GPs to better guide antibiotic treatment by ruling out pneumonia in cases of low test results. Alternatively, enhanced communication skills training to help clinicians address patients' expectations and worries could lead to a decrease in antibiotic prescribing, without compromising clinical recovery, while enhancing patient enablement. The aim of this paper is to describe the design and methods of a study to assess two interventions for improving LRTI management in general practice.Methods/DesignThis cluster randomised controlled, factorial trial will introduce two interventions in general practice; point of care CRP testing and enhanced communication skills training for LRTI. Twenty general practices with two participating GPs per practice will recruit 400 patients with LRTI during two winter periods. Patients will be followed up for at least 28 days. The primary outcome measure is the antibiotic prescribing rate. Secondary outcomes are clinical recovery, cost-effectiveness, use of other diagnostic tests and medical services (including reconsultation), and patient enablement.DiscussionThis trial is the first cluster randomised trial to evaluate the influence of point of care CRP testing in the hands of the general practitioner and enhanced communication skills, on the management of LRTI in primary care. The pragmatic nature of the study, which leaves treatment decisions up to the responsible clinicians, will enhance the applicability and generalisability of findings. The factorial design will allow conclusion to be made about the value of CRP testing on its own, communication skills training on its own, and the two combined. Evaluating a biomedical and communication based intervention ('hard' and 'soft' technologies) together in this way makes this trial unique in its field.
