Hypothesis
What is the clinical utility of broad-range PCR testing in guiding antimicrobial treatment for adults with suspected infections?
Conclusion
Broad-range PCR testing can significantly support antimicrobial stewardship by informing treatment decisions, even in cases with negative results.
Supporting Evidence
- BR-PCR was positive in 30% of specimens, indicating its potential effectiveness.
- Clinical utility was identified in 29.5% of specimens, including cases with negative BR-PCR results.
- De-escalation of antimicrobial therapy occurred in 9.5% of cases.
- Clinical utility varied significantly by specimen type, with cranial samples showing the highest utility.
Takeaway
This study shows that a special test called broad-range PCR can help doctors choose the right medicine for sick people, even when the test doesn't find any germs.
Methodology
A retrospective cohort study evaluating clinical specimens that underwent broad-range PCR testing between 2017 and 2021.
Potential Biases
Potential bias due to the reliance on clinical documentation and the possibility of misclassification of results.
Limitations
The study is retrospective, which may lead to misclassification of clinical utility due to incomplete documentation.
Participant Demographics
Hospitalized adults (≥18 years old) from a large hospital system in northeast Ohio.
