Chest x-ray follow-up for patients admitted with SARS-COV-2 infection in Leeds Teaching Hospitals (LTHT)

Abstract

<b>Background:</b> Chest x-ray (CXR) abnormalities are common in patients admitted acutely with SARS-COV-2 infection. We aimed to identify the proportion of LTHT in-patients with SARS-COV-2 infection who have full resolution of CXR changes within the study period. <b>Methods:</b> We created a database of adult LTHT in-patients who were confirmed SARS-COV-2 positive on PCR testing between March - April 2020 where initial CXR were coded as either Likely/Suspicious or Indeterminate for COVID-19 infection. We used our integrated electronic records system to identify patients with initial and repeat CXR (for any indication) up-to December 2020. We identified 123 patients who met the inclusion criteria. <b>Results:</b> The average age of patients was 69.2 years (range 20 to 97). The average time from initial CXR to follow-up scan was 89 days. 94 (76%) of repeat CXR showed full resolution of initial abnormalities during the study period (see Figure 1). CTPA/ HRCT were requested for 11 patients with persistent abnormalities and symptoms. 1 patient was positive for PE. Management did not change for the remaining patients. <b>Measurements and Main Results:</b> Our data shows full resolution of CXR changes occurs for three quarters of patients admitted with SARS-COV-2 infection. Further imaging for patients with persisting abnormalities rarely led to change in management. This may warrant further study of the timing and benefit of CXR follow-up for this patient group.
