In a cohort of 300 university students, the use of a rapid polymerase chain reaction (PCR) test for influenza did not significantly improve the likelihood of guideline consistent care. Students presented with cough and 1 influenza-like illness symptom at a university health clinic to receive care guided by a PCR test. Of the 300 patients receiving the PCR test, 264 had complete medical records and were compared to 771 who received usual care. Researchers found:

• Logistic regression found that the odds of receiving guideline supported care did not significantly increase for patients receiving PCR guided care.
• It significantly decreased the likelihood of an antibiotic prescription.
• It also decreased the likelihood of return visits within 2 weeks.
