Impact of COVID-19 pandemic on the activities of Dental Clinic of University Hospital Center Zagreb

Abstract

Aim: The aim of this study was to show the impact of the pandemic on changes in guidelines for clinical work and the number of patients of the Clinic of Dentistry, University Hospital Centre (UHC) Zagreb, in the period of normal work before the pandemic and in subsequent years. Methods: From the data base of the hospital information system of UHC Zagreb data were retrospectively collected on the total number of cases at the Clinic of Dentistry in each period and the total number of cases at individual departments, for the period from January 1 to November 11, in 2018, 2019, 2020 and 2021. Results: During the pandemic period the most significant decrease in the number of patients in majority of organizational units was evident in 2020 compared to 2018, when a decrease in the number of patients of 30.27% was recorded, while in 2021, compared to 2018, the number of patients decreased by 9.73 %. The Department of Oral Surgery and the Department of Orthodontics had an almost unchanged number of patients in 2020 compared to 2018, while in 2021, compared to 2018, there was an increase in the number of patients. Rebro Dental Clinic and One-day surgery also recorded an increase in the number of patients. At the time of the epidemiological recommendations on the introduction of cold drive, these units of the Dental Clinic also treated other, less urgent diagnoses that would lead to bad consequences if delayed. During the collective annual leave of all other organizational units of the Dental Clinic, these units take over the provision of all necessary services of the Dental Clinic. Conclusion: COVID-19 pandemic has led to a reduction in the number of patients at the level of the Dental Clinic. The inability to treat teeth in a timely manner resulted in increased need for extractions and an increase in the number of patients at the Department of Oral Surgery. In 2021 there was a greater or lesser increase in the number of patients in individual departments, which, however, in the observed period has not yet reached the numbers from 2018. In the coming months, a further increase in the number of patients and elective dental procedures is expected.
