Role of the otolaryngologist in nasopharyngeal swab training: A case report and review of the literature

Abstract

Nasopharyngeal swabs are commonly done in the medical field for a multitude of reasons, and they recently have been an essential component of widespread testing to control the spread of COVID-19. Although rare, improper technique when performing nasopharyngeal swabs has the potential to lead to injury or misleading test results. We present a case of uncontrolled epistaxis requiring hospitalization following a routine nasopharyngeal swab in a healthy patient. Both the complexity and variability of the anatomy of the nasopharynx can contribute to poor swabbing technique. Otolaryngologists should be encouraged to educate and support other healthcare workers to improve the yield and reduce the risk of harm due to nasopharyngeal swabs. Increased comfort levels with performing nasopharyngeal swabs will also improve the sensitivity of screening tests for common respiratory viruses such as influenza, Epstein-Barr virus (EBV), or bacteria such as Staphylococcus aureus.
