Point-of-Care Testing Cuts Antibiotic Use in Pharyngitis
TOPLINE:
Point-of-care testing for group A beta-hemolytic Streptococcus (Strep A) significantly reduced antibiotic prescriptions in children and adults with signs of pharyngitis, even when used as the sole intervention.
METHODOLOGY:
Researchers performed a meta-analysis of eight randomized controlled trials conducted between 2007 and 2021, evaluating point-of-care testing for Strep A vs standard care.
The analysis included 4249 children and adults with pharyngitis, cough, or sore throat who underwent point-of-care testing for Strep A either alone or alongside other interventions.
Primary outcomes were the impacts on antibiotic prescriptions, clinical decisions, and patient health outcomes.
Secondary endpoints assessed diagnostic accuracy of Strep A testing, including sensitivity and specificity measurements.
TAKEAWAY:
Point-of-care testing reduced antibiotic prescriptions by 38% compared with standard care (risk ratio [RR], 0.62; P < .0001) and by 41% when it was the sole intervention (RR, 0.59; P < .001).
The implementation of point-of-care testing also led to a reduction in inappropriate antibiotic prescriptions (RR, 0.45; 95% CI, 0.31-0.97; P = .038).
However, there were no significant differences in the patient health outcomes, such as days until pain resolution and days of school/work missed, the use of ancillary testing, or other medications such as analgesics with point-of-care testing.
The reported diagnostic accuracy of Strep A point-of-care testing showed sensitivity ranging from 65% to 94% and specificity from 85% to 94%.
IN PRACTICE:
'Physicians can therefore use Strep A POCTs [point-of-care tests] to inform their decisions on antibiotic prescribing without compromising patient health outcomes. In clinical practice, physicians must be aware of the limitations of Strep A POCTs, in particular, the limited sensitivity for detecting GAS [group A beta-hemolytic Streptococcus],' the authors of the study wrote.

This study was led by Ann-Sophie Mägdefrau and Carolin Kathner-Schaffert, Jena University Hospital and InfectoGnostics Research Campus Jena, both in Jena, Germany. It was published online on July 9, 2025, in Open Forum Infectious Diseases.
LIMITATIONS:
High statistical heterogeneity in the meta-analyses limited the precision of the pooled effect estimates. Only three trials reported patient health outcomes, restricting evaluation of the effect of Strep A point-of-care tests on measures like recovery time. Additionally, none of the trials were blinded, introducing potential bias — particularly in evaluating subjective outcomes like pain and symptom resolution.
DISCLOSURES:
This study received funding from the German Federal Ministry of Education and Research. The authors reported having no relevant conflicts of interest.
