Impact of introduction of xpert flu assay for influenza PCR testing on obstetric patients: a quality improvement project.

OBJECTIVE

The aim of this project was to assess the implementation of a quality improvement project regarding the introduction of on-site influenza PCR testing in a stand-alone obstetric hospital.

METHODS

As part of a quality improvement project on the management of influenza in obstetric patients, the Xpert Flu assay (Cepheid Inc., Sunnyvale, CA) was introduced on-site and it replaced the previous method of PCR testing which was off-site. The main outcome measures were duration of antimicrobials, rate of admission and administration of oseltamavir in the emergency department.

RESULTS

Twenty-eight patients were included in the pre-intervention period and 45 patients were included in the post-intervention period. Following the introduction of the test, there was a statistically significant reduction seen in commencement of antimicrobials (76% pre- and 33% post-intervention), and also rate of admission (88% pre- and 45% post-intervention) while there was a statistically significant improvement in the commencement of oseltamavir in the emergency department (72% pre-and 95% post-intervention) (p < .01 for all outcomes).

CONCLUSION

Introduction of on-site rapid influenza PCR testing can lead to a significant improvement in patient management and should be considered for introduction to other sites.
