ABSTRACT
Background:
We conducted this study to assess the diagnostic test properties of point of care ultrasonography (POCUS) of lung and cardiovascular system in prediction of mortality in COVID-19 patients.Methods:
This is a cross-sectional study of 178 Covid-19 patients; POCUS was performed within one hour of admission to the ICU. We estimated sensitivity, specificity, positive predictive value, negative predictive value for prediction of mortality.Results:
The mean (SD) age of these patients was 57.3 (12.8) years. The findings were on cardiac ultrasonography were mild pericardial effusion (45%), chamber dilatation (15%), hypokinesia (11%), and low ejection fraction (8%). In our study, 30 patients (17%) had died. A cut-off score of > to 13 (for lung ultrasound score [LUS]) had high sensitivity for mortality (93.3%, 95% CI 77.9-99.2%). However, low ejection fraction (92.3%, 95% CI 86,6-96.1%), and thrombosis in either vein (96.5%, 95% CI 92.0-98.9%) were specific for mortality. A combination of LUS > =13 or low ejection fraction or thrombosis or spontaneous echo contrast (slow flow) improved sensitivity for mortality to 96.7% (95% CI 82.8-99.9%). The agreement between LUS of > =13 and CT score of moderate/severe was 85.7% (95% CI 62.8-100%). The interrater agreement between these two parameters was 0.82 (95% CI 0.68, 0.97).Conclusions:
Multi-organ POCUS is effective in diagnosis, prognosis, and management of COVID-19 patients. Rather than just lung ultrasound, clinicians should use multiorgan POCUS for early identification of severe lung involvement and thrombotic changes; it may help reduce mortality in these patients.
