Outcomes of a Negative Rapid Influenza Diagnostic Test in Pregnant Women.
Journal Article
OBJECTIVE: The objective of this study was to evaluate the negative predictive value (NPV) of a rapid influenza diagnostic test (RIDT) compared with polymerase chain reaction (PCR) in pregnant women. STUDY DESIGN: Retrospective cohort study of pregnant women with a negative RIDT followed by confirmatory PCR for influenza A, H1N1, and B during the influenza seasons from 2012 to 2015. RESULTS: The NPV of the RIDT was 85.4% (211 of 247), 93.5% (231 of 247), and 97.9% (242 of 247) for influenza A, H1N1, and B, respectively. Antiviral treatment was administered to 47.2% (17 of 36) of women with a false-negative RIDT for influenza A compared with 9.0% (19 of 211) of women with a true-negative RIDT (p< 0.001). Patients were more likely to receive antiviral treatment if they were feverish (adjusted odds ratio [aOR]: 6.05, 95% confidence interval [CI]: 1.83-20.03), had cough (aOR: 6.43, 95% CI: 1.06-39.26), dyspnea (aOR: 6.41, 95% CI: 1.63-25.29), or had a subsequently positive PCR (aOR: 9.41, 95% CI: 3.13-28.31). CONCLUSION: Up to 14.5% of women with a negative RIDT in pregnancy had positive influenza A by PCR of whom more than half did not receive antiviral treatment.
