Abstract WP46: Patterns Of Emergency Medical Transport For Suspected Acute Stroke, Acute Myocardial Infarction, And Other Diagnoses During The Covid-19 Pandemic: A Retrospective Analysis Of A Large Hospital-based Emergency Medical Services (EMS) Agency


 Introduction:
 During the initial peak of the COVID-19 pandemic, many centers globally reported a significant decrease in volumes of emergencies including acute stroke (AS) and acute myocardial infarction (AMI). While the reason for this remains unknown, pandemic-driven anxiety among patients may have resulted in unwarranted refusals to transport when deemed necessary by EMS (Emergency Medical Services) providers. We sought to study the impact of COVID-19 pandemic on the patterns of Emergency Medical transport (EMTr) and patient refusals to transport when serious medical conditions were suspected by EMS personnel.
 
 
 Methods:
 In this retrospective, observational study of Grady Health System’s EMS, we compared the rates of EMTr and refusals for adult patients with suspected diagnoses of AS, AMI, and other medical conditions in the first year of the pandemic (Y1, Mar 2020-Feb 2021) with the corresponding period in the year prior (Y0). We also compared the temporal trends for these variables across the different pandemic waves (1

 , Mar-May 2020; 2
 nd
 , Jun-Aug 2020; 3
 rd
 , Sep 2020-Feb 2021) with the corresponding periods in the year before.
 
 
 Results:
 Grady EMS responded to 207,888 calls in Y1 compared to 201,968 in Y0. The overall rate of refusals for all diagnoses was 15.5% in Y1 vs 14.1% in Y0, that for AS was 2.25% in Y1 vs 1.77% in Y0 and 7.5% in Y1 vs 5.67% in Y0 for AMI (Figure).
 
 
 Conclusion:
 There were more refusals in the first two waves of the pandemic. While refusals were higher for AS and AMI, this was not statistically significant. Our study provides valuable insight into the behavioral patterns of patients seeking emergency care during the pandemic and emphasizes a need for public education and more research.
