OBJECTIVE: It is possible to diagnose coronavirus disease 2019 (COVID-19) faster and more accurately with chest X-ray (CXR) and chest computed tomography (CT) than with reverse transcriptase PCR (RT-PCR) tests. The aim of this study was to verify the possibility of reducing the use of CT in diagnosis and follow-up of COVID-19 infection by using CXR.

PATIENTS AND METHODS: A total of 326 COVID-19 patients who were hospitalized in Ankara City Hospital were included in this retrospective study.

RESULTS: A total of 326 patients were RT-PCR positive for COVID-19 infection; 178 were male (54.6%) and 148 were female (45.4%), with a median age of 45. Considering the results, the baseline CXR sensitivity in our experience was approximately 72%. The CXRs of 113 patients with abnormal CT were divided into 2 groups, the CXR normal and abnormal groups, and were then compared. In the 1st group with abnormal CXR, the mean age, the number of patients over 65 years old, and the comorbidity rate were higher. Additionally, it was determined that the number of patients requiring respiratory support and intensive care unit (ICU) admission in this 1st group was higher than in the 2nd group (with normal CXR). Most of the patients who died (91%, 10/11) were in Group 1. In the group with normal CXR, no patients in the critically ill category needed invasive or non-invasive mechanical ventilators.

CONCLUSIONS: CXR can help in detecting clinically moderate and severe cases of COVID-19. CXR can assist clinicians in patient management and treatment planning regarding the clinical course, respiratory support, ICU need, and mortality and can help them prepare for potential negative outcomes.
