ABSTRACT
BACKGROUND:
Due to the relative early lockdown in India, relative greater availability of reverse transcription polymerase chain reaction (RT-PCR) testing, and mandate to admit all positive corona virus disease 2019 (COVID-19) patients, the protocol in our hospital is to perform a baseline chest X-ray (CXR) at the time of admission and for follow up. There are currently limited publications demonstrating the radiographic findings and the role of CXR of COVID-19 patients at presentation.AIMS:
Evaluatethe radiographic findings on CXR in COVID-19 patients at presentation. Recommend a guideline for its judicious use. SETTINGS ANDDESIGN:
Retroprospective study performed on RT-PCR confirmed COVID-19 patients admitted in our hospital between March 31,2020 to May 25, 2020. The study included symptomatic and asymptomatic patients. CXR was performed for218 patients. MATERIALS ANDMETHODS:
Portable bedside CXR was performed. The CXRs were evaluated by three radiologists to record the findings and grade the disease. All variables were expressed as mean, ranges, counts, and percentages.RESULTS:
157 patients (72%) were symptomatic and 61 (28%) were asymptomatic. 104 CXRs (48%) were abnormal (97 in symptomatic (62%) and fourin asymptomatic (6%)). 74 patients (47%) in the symptomatic group had known comorbidities and of these, 62 (84%) had abnormal CXR. 97 CXRs (93%) had bilateral findings and 87 CXRs (84%) had peripherally predominant abnormalities. The lower zone was the most common area of involvement (73%). Ground glass opacity (GGO) was the most common finding (94%-98 CXRs). Mild disease was seen in 56 (54%).CONCLUSION:
CXR can be used to assess symptomatic COVID-19 patients at presentation and to grade the severity of disease. It may be avoided in asymptomatic patients.
