Antibiotic Therapy, Prostate Biopsy
Conditions
Brief summary
The study is a randomized controlled trial. Subjects are randomly assigned 1:1 to receive either rapid multiplex qPCR (intervention) prior to standard of care prostate biopsy or standard of care (control) prostate biopsy. The subjects will have a rectal culture swab performed prior to the prostate biopsy. One rectal culture swab will be used for rapid multiplex qPCR and the other swab will be sent to microbiology for a standard culture. The subjects randomized to the intervention group will have the qPCR results shared with the physician to determine if additional standard of care antibiotics are needed at time of standard of care prostate biopsy. The subjects randomized to the control group will not have the qPCR results shared with the physician to determine if additional standard of care antibiotics are needed at time of standard of care prostate biopsy. Approximately, 10 days after the prostate biopsy, the research staff will conduct a chart review and/or telephone call to ask about any prostate biopsy infections and complications.
Interventions
OTHERrPCR results
Interventional group: rPCR results will be shared with the clinical provider to determine appropriate standard of care antibiotic treatment at time of standard of care prostate biopsy.
OTHERControl group
Control group: rPCR results will not be shared with the clinical provider at time of standard of care prostate biopsy. Standard of care antibiotic selection will be up to the discretion of the clinical provider.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Results of rapid qPCR to determine standard of care antibiotic prophylaxis for prostate biopsy. | Day of prostate biopsy | Reduction in dual antibiotic prophylaxis in the intervention vs.usual care groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Determine if rapid qPCR test results in longer patient wait times. | Day of prostate biopsy | Difference in the amount of time the PCR technique takes compared to the fastest workflow (physician chooses no additional antibiotics). |
| Determine if rPCR results and standard rectal culture results are the same. | 1 week | Comparison of rPCR results to standard rectal culture on Fluoroquinolone infused MacConkey agar. |
