Abstract

This study aims to describe and compare clinical symptoms, and radiographic characteristics, both in chest radiograph and chest CT scan, of patients under investigation for the 2019 Novel Coronavirus Disease (COVID-19) who underwent RT-Polymerase Chain Reaction test in De La Salle University Medical Center, Dasmariñas Cavite. This was a retrospective cross-sectional analytic study composed of 25 patients who are classified as patients under investigation and has underwent chest radiograph, chest CT scan and RT-PCR testing during the period of January 1, 2020 to June 30, 2020 in De La Salle University Medical Center, Dasmariñas, Cavite. Fatigue and sore throat, among all clinical presenting symptoms, had the highest accuracy, both having a 64% overall probability of having a patient with radiographic findings in chest radiography and chest CT scan that are typical of COVID-19, regardless of RT-PCR test result for COVID-19. Overall, fever and difficulty of breathing were the most accurate in detecting a positive result based on RT-PCR with 64% and 60% accuracy, respectively. Gathered data showed that both chest radiography and chest CT scan are not significant and does not accurately detect patients infected with COVID-19 and are not beneficial/helpful as initial diagnostic tools in the management of COVID-19. Rather, presence of clinical symptoms especially fever and difficulty of breathing yields a high index of suspicion of having a patient infected with COVID-19 and these patients.
