- Abstract
Objectives: Safety precautions limit the clinical assessment of hospitalized Coronavirus disease 2019 (COVID‐19) patients. The minimal exposure required to perform lung ultrasound (LUS) paired with its high accuracy, reproducibility, and availability make it an attractive solution for initial assessment of COVID‐19 patients. We aim to evaluate whether the association between sonographic findings and clinical outcomes among COVID 19 patients is comparable between the validated 12‐zone protocol and a shorter, 8‐zone protocol, in which the posterior lung regions are omitted. Methods: One hundred and one COVID‐19 patients hospitalized in a dedicated COVID‐19 ward in a tertiary referral hospital were examined upon admission and scored by 2 LUS protocols. The association between the scores and a composite outcome consisting of death, transfer to the intensive care unit (ICU) or initiation of invasive or noninvasive mechanical ventilation was estimated and compared. Results: LUS scores in both the 8‐ and the 12‐zone protocols were associated with the composite outcome during hospitalization (hazard ratio [HR] 1.21 [1.03–1.42, P =.022] and HR 1.13 [1.01–1.27, P =.037], respectively). The observed difference in the discriminatory ROC‐AUC values for the 8‐ and 12‐zone scores was not significant (0.767 and 0.754 [P =.647], respectively). Conclusion: A short 8‐zone LUS protocol is as accurate as the previously validated, 12‐zone protocol for prognostication of clinical deterioration in nonventilated COVID‐19 patients.
