		        	Abstract:
			       	
			       		
				        
				        	 Background:We performed a nationwide analysis to evaluate the impact of the early coronavirus disease 2019 (COVID-19) pandemic on emergency department (ED) visits by adult cancer patients having COVID-like symptoms. 
				        	
				        
				        	Methods:We analyzed the National Emergency Department Information System (NEDIS) data on ED visits by adult cancer patients who presented with chief complaints of fever or respiratory symptoms (FRS) indicative of COVID-19, from 2016 to 2020. An interrupted time series analysis with a quasi-Poisson regression model was performed, adjusting for seasonality and time, to evaluate whether underlying trends for monthly ED visits and the in-hospital mortality rate (%) per month changed with the pandemic among these patients.We also estimated the adjusted odds ratio (aOR) of in-hospital deaths among cancer patients using multivariable logistic regression analysis. 
				        	
				        
				        	Results:ED visits by cancer patients with FRS decreased during the COVID-19 pandemic (relative risk [RR] with 95% confidence interval [CI]: slope change, 0.99 [0.98–1.00] and step change, 0.84 [0.76–0.92]). However, the in-hospital mortality rate (%) for these patients was increased (slope change, 1.14 [1.04–1.25] and step change, 0.99 [0.98–1.01]). Factors such as urgent triage status, ambulance use, and treatment in hospitals with fewer than 300 staffed beds significantly contributed to increased aOR of in-hospital deaths during the COVID-19 pandemic compared to the pre-pandemic period. 
				        	
				        
				        	Conclusion:Further studies are needed to highlight the importance of ED service preparation in planning and managing resources for cancer patients during future pandemics.
