COVID-19 as a turning point in the need for specialized units for the sense of smell

Abstract

The high prevalence of olfactory dysfunction (OD) by SARS-CoV-2 has revealed the lack of specialized units [1,2]. The main objective is to know the new olfactory units (OU) since the COVID-19 pandemic, and to evaluate the tests used for diagnosis, management and treatment of OD and providing up-to-date data on the current practice in Spain. Due to the increase in COVID-19 and other diseases related to OD, the creation of new OUs is necessary, considering that OD is a predictive symptom of these diseases that affects all ages [3]. To our knowledge this is the first study on OU and no studies were found in other countries. A prospective cross-sectional study, carried out by means of a survey that contains 17 items (supplementary file 1). The survey was developed by 6 experts and was distributed to all members of Spanish ENT and Allergy societies through the Google platform. We considered the "OU" to be a team (ENT or Allergist) with the infrastructure and staff to perform the assigned functions (validated test, well ventilated cabin with controlled humidity and temperature). Statistical analysis was performed with STATA using Shapiro Wilk test, chi-2 test and Spearman correlation analysis. Finally, 136 facilities were included (112/82.4% otolaryngologist and 24/17.6% allergists).
