Characteristics of visits from otolaryngological patients before and during three waves of the COVID-19 pandemic: A retrospective study.

Abstract

Introduction: COVID-19 pandemic has had a significant impact on healthcare systems around the world. The rapid spread of the virus caused several restrictions, including limited access to outpatient clinics. The purpose of the study was to compare the characteristics and reasons of the visits of otolaryngological patients conducted during the first three waves of the COVID-19 pandemic with those of the prepandemic period.

Materials and methods: Volume, demographic data, type of visits, additional tests, referral types, and reasons for consultation were analyzed.

Results: There were 1578 visits performed before the pandemic and, respectively, 434, 1198 and 1299 during the first, second and third waves. The patients in the first and second waves were older than the patients before the pandemic (mean age 59, 56, and 52 years, respectively, for both comparisons p<0.0001). Regarding the type of visit, the vast majority were in-person visits in all groups. The highest percentage of teleconsultations was in the first wave and was equal to 3.46%. Before the pandemic, patients were admitted mainly due to upper respiratory system diseases (52.15%), while during the first wave the main reasons were tumors (39.86%, malignant and benign tumors comprised 29.26% and 10.6%, respectively).

Conclusions: The COVID-19 pandemic, especially the first wave, changed the profile of ambulatory patients. In the first wave, a higher prevalence of tumor patients and a lower prevalence of patients with diseases of the upper respiratory system were observed. The COVID-19 pandemic caused an increase in number of teleconsultations, but its role was limited.
