Methods: Retrospective analysis of 217 patients, mean age 71.8 (SD 8.7, range 29-87) years, admitted March to May 2020 and subsequently tracked. Patients requiring >40% FiO2, and/or respiratory device support had severe disease and CXRs were normal or abnormal to COVID changes. Data analysed using statistical software reporting comparisons by chi square (X2).
Results: Initial CXRs for 123/213 (58%) patients were abnormal; 59/153 (39%) surviving admission attended follow up; others defaulted or were not requested with normal CXR or expected poor prognosis. 39 (66%) CXRs improved, 20 (34%) remained abnormal; of these, 9 patients had chest CT scans. Severe disease contributed to higher mortality, respectively 37/58 (64%) versus 46/159 (29%), X2 (df 1, n=217) 21.87, p=.0001. Comparing abnormal with normal CXR, 47/122 (39%) versus 11/91 (12%) had severe disease, X2 (df 1, n=213) 18.38, p=.000018. 55/123 (45%) versus 28/90 (31%) of those with initial abnormal CXR have since died, X2 (df 1, n=213) 4.04, p=.0044.
Conclusions: Mortality is associated with both the severity of illness and initial COVID related abnormal CXR; 58% have such changes at presentation and among the survivors having follow up radiology improves in two-thirds with approximately half the others then investigated by chest CT giving some indication to planning future services.
