Assessment of lung injury severity using ultrasound in critically ill COVID-19 patients in resource limited settings
Authors' conclusion
Lung ultrasound was feasible and contributed to characterize lung injury in critically-ill COVID-19 patients in a low income setting. Lung ultrasound score was associated with oxygenation impairment and mortality.
Study context
- Population
- Critically ill COVID-19 patients admitted to a university hospital intensive care unit (ICU) in Mali (low-income setting)
- Participants
- 156 patients
- Outcome
- Usefulness of lung ultrasound in assessing severity of SARS-CoV-2 infection

Main finding
As reported in the abstract
Lung ultrasound feasibility, reproducibility and score
- Feasibility: quadrants assessed
- 1802/1872 (96%)
- Reproducibility: intra-class correlation coefficient of elementary patterns
- 0.74 (95% CI 0.65, 0.82)
- Coefficient of repeatability of lung ultrasound score for an overall score of 24
- < 3
- Confluent B lines (most common lesions)
- 155/156
- Overall mean ultrasound score (± SD)
- 23 ± 5.4
- Correlation of ultrasound score with oxygen saturation (Pearson, p < 0.001)
- - 0.38
Observational data: associations, not effects.
Further findings
Mortality
- Died
- 86/156, 55.1%
- Factors associated with mortality (multivariable): age, number of organ failures, therapeutic anticoagulation, lung ultrasound score
Respiratory status at admission
- Respiratory failure at admission
- 96%
- Needed respiratory support
- 121/156, 78%
