A Single-Center Study of the Impact of the COVID-19 Pandemic on the Organization of Healthcare Service Delivery to Patients with Head and Neck Cancer

The aim of this study was to identify and assess the impact of the COVID-19 pandemic on the diagnosis and treatment of head and neck cancer (HNC) patients of the Department of Otolaryngology, Head and Neck Surgery of the 4th Military Teaching Hospital in Wroclaw for whom oncological treatment was planned by a cancer case board between March 2018 and February 2022. We analysed the medical records of 625 patients. In order to verify whether the relationships between the analysed features were statistically significant, the chi-square test of independence and the Student's t-test for independent samples were used (p < 0.05). Our analysis showed that the impact of the pandemic on the organization of health service delivery to HNC patients was not uniform. The largest difference in the number of formulated treatment plans was observed at the beginning of the pandemic (22.1% reduction compared with the year before the pandemic). During the pandemic, the proportion of patients admitted on the basis of a DILO (diagnosis and oncological treatment) card issued by a primary care physician, instead of a regular referral to hospital, issued also by a primary care physician, was significantly higher compared with the that during the pre-pandemic period. The majority of cancer patients with a oncological treatment planned during the pandemic lived in urban areas. During the pandemic, the number of patients with more-advanced-stage cancer, assessed on the basis of the type of planned treatment (radical vs. palliative), did not increase compared with that during the pre-pandemic period. However, our follow-up period was quite short. It is necessary to intensify activities aimed at promoting health and increasing health awareness in people living in rural areas and setting long-term priorities and objectives for health policies at the national, regional and local levels, with particular focus on this group of people.
