Review of COVID-19 vaccinated patients' emergency room admissions

Introduction: This study was aimed to define the demographic structure of vaccinated patients admitted to the emergency room (ER) with COVID-19 symptoms, and their hospitalization status, length of stay (LoS) in hospital, and mortality status. Material and Method: This research is a retrospective, cross-sectional and descriptive study. Furthermore, it includes the period between 15.01.2021 and 30.04.2021. Results: An 887 COVID-19 vaccinated patients who applied to ER. Of these, 383 (42.2%) were male, and 504 (56.8%) were female. The mean age of the patients was 52±18.6 years. The number of single-dose vaccinated patients was 696 (78.5%), and the two-dose vaccinated was 191 (21.5%). CoronaVac (Sinovac Life Sciences) vaccine was applied to 755 (85.1%), and BNT162b2 (Pfizer & Biontech) vaccine was applied to 132 (14.9%) patients before. In 317 (35.7%) cases, reverse transcription-polymerase chain reaction (Rt-PCR) positivity was detected in the ER application after vaccination. Of the total patients, 86 (9.7%) were hospitalized, 14 (1.4%) patients died in the hospital. The mean time between vaccination and application to ER was 25 (±21.9) days. Also, this period was 28.1 (±18) days in two-dose vaccinated patients. Conclusion: People who are vaccinated with the COVID-19 vaccine continue to have hospital admissions with COVID-19 symptoms. Rt-PCR positivity, need for hospitalization, and mortality may continue to be seen in vaccinated individuals.
