Abstract

Background During the COVID-19 pandemic, many hospitals suspended non-essential medical procedures to reduce transmission and prioritize personal protective equipment (PPE) for COVID-19 patients. Hospitals that continued these procedures faced uncertainty about patient attendance. Multiple factors could explain a decline in patient attendance during the pandemic, including patients' reluctance to risk COVID-19 exposure in the hospital or their own illness requiring self-isolation. This study aimed to compare attendance rates of lung cancer screenings (LCS) before and during the pandemic. Unlike previous studies conducted on this research topic, the current study documents that the John B. Amos Cancer Center continued LCS throughout the pandemic. The alternative hypothesis was that there would be a decrease in the percentage of LCS performed during the pandemic period due to fear of nosocomial transmission. Materials and methods Data for 2,582 scheduled LCS were retrospectively analyzed on Microsoft Excel 2022 (Microsoft Corporation, Redmond, Washington) from 2018 to 2021. For analysis purposes, 2018 and 2019 were considered pre-COVID years, while 2020 and 2021 were considered COVID years. The average percentage attended was calculated for each year and the standard deviation of that year's percentage. The percentage of patients seen each month was averaged during pre-COVID and COVID years. The p-value was calculated by comparing the average attendance percentage for each month in the pre-COVID and COVID years. A p-value <0.05 was considered significant. Results From 2018 to 2021, over 300 more people were scheduled during the COVID years. Although the percentage seen remained consistent throughout the years, there was an increase in both patients scheduled and seen. The results revealed an insignificant difference in LCS attendance between pre-COVID and COVID years, confirming the importance of their continuation. Conclusion The alternative hypothesis was rejected due to no significant difference in attendance percentage between the pre-COVID and COVID years. Further direction of this study may include monitoring the trend of LCS attendance during post-pandemic years as the transmission rates continue to change.
