Optimization of COVID-19 testing accuracy with nasal anatomy education.


ABSTRACT:

Importance

Adequate sampling of the nasopharynx is crucial to performing accurate SARS-CoV-2 (COVID) testing. Formalized education of nasal anatomy may improve provider testing technique and reduce false-negative test results.

Objective

To assess the effect of nasal anatomy education on medical providers' comfort level and knowledge base in performing accurate SARS-CoV-2 (COVID) testing.

Study design

Pre-post survey.

Settings

Tertiary care academic hospital.

Participants

17 nurses performing COVID testing were enrolled.

Intervention

An educational session on COVID nasopharyngeal testing technique and nasal anatomy was presented by an otolaryngologist.

Main outcomes and measures

A pre-session survey assessed providers' prior nasal testing training and COVID testing challenges. Provider comfort level with COVID testing was surveyed pre-and post-session. A 6-question nasal anatomy test was administered pre- and post-session.

Results

16 out of 17 nurses performed fewer than 10 COVID tests prior to the educational session (94%). Reported challenges with COVID testing included patient discomfort (79.6%), inability to pass the test swab (23.5%) and nasal bleeding (11.8%). The number of providers comfortable with independently performing COVID testing increased from pre- to post-session (5 and 14, p = 0.013). The average number of correct responses to the 6-question nasal anatomy test increased following the session (3.2 ± 1.2 to 5.1 ± 1.1, p = 0.003). Specifically, the number of providers able to localize the nasopharynx increased from 8 providers pre-session to 14 providers post-session (p = 0.04).

Conclusion

Early implementation of nasal anatomy and nasopharyngeal swab technique education can help improve provider comfort and knowledge in performing accurate COVID testing.
