Are multiple sinus cultures necessary during sinus surgery for chronic rhinosinusitis?

Background

Multiple cultures are commonly obtained from different sinuses where purulence is encountered during endoscopic sinus surgery (ESS). This brings into question the utility and necessity of obtaining multiple cultures. The purpose of this study was to evaluate if multiple cultures obtained during a single case is informative in finding additional pathogens or if it is a redundant, cost-increasing practice. We hypothesized that multiple sinus cultures are necessary to identify the pathogens responsible for an individual's sinus disease. We seek to add information on the utility of performing multiple sinus cultures from a patient care and a health economics standpoint.

Methods

This study was a retrospective review of a single rhinologist's surgical database from 2008 to 2016. Patients that underwent ESS for chronic rhinosinusitis (CRS) and had multiple cultures obtained during surgery were included. Culture difference was recorded as a discrepancy of an infectious pathogen between cultures.

Results

We identified 231 patients with multiple sinus cultures. Of those, 39.4% had a difference of pathogens noted on culture between different sinuses. Only 5% of the cohort received clinically relevant benefit from the second culture obtained in regard to a change in antibiotics.

Conclusion

In this retrospective review we showed that, for the practitioner who obtains sinus cultures intraoperatively, limiting this practice to a single culture rather than multiple is cost-effective and sufficient for identifying the pathogen to be treated. This study, and the resultant change in practice, has the potential to reduce healthcare costs associated with the surgical care of the patient with CRS.
