Impact of Real-Time Multiplex PCR Testing for Respiratory Viruses on Antibiotic Use.

OBJECTIVE

Real-time multiplex polymerase chain reaction (PCR) test increases the detection of viral respiratory tract infections. This study aimed to evaluate the effect of real-time multiplex PCR on antibiotic use in viral respiratory tract infections.

MATERIALS AND

METHODS

This retrospective study included patients who underwent respiratory multiplex PCR tests. Patients were grouped into influenza-like illness, viral pneumonia, bacterial pneumonia, and co-infection. These groups were compared in terms of antibiotic use.

RESULTS

This retrospective study included patients who underwent respiratory multiplex PCR tests. Patients were grouped into influenza-like illness, viral pneumonia, bacterial pneumonia, and co-infection. These groups were compared in terms of antibiotic use.

CONCLUSION

Despite a confirmed viral etiology by PCR, antibiotic use remained high, particularly in cases of viral pneumonia. These findings underscore the need for targeted antimicrobial stewardship interventions, including clinician education and integration of diagnostic-therapeutic approaches, to optimize antibiotic prescribing in respiratory infections.
