TOMAINO, María Victoria; BARLETTA, José AE  and  ROLON, María José. Simple clinical score for rational use of lung ultrasound in COVID-19 outpatient settings. Rev. argent. salud pública [online]. 2022, vol.14, suppl.1, pp.51-51.  Epub July 15, 2022. ISSN 1852-8724.


Due to the rapid global expansion of COVID-19, Febrile Emergency Units (FEU) were created in the outpatient setting to stratify the clinical risk of patients. Pulmonary ultrasound has gained a growing interest as a sensitive method for the detection of pneumonia. This study aimed to at developing a simple and sensitive score to assess the risk of pneumonia during the first COVID-19 wave.


A cross-sectional study was conducted in a cohort of adult patients with laboratory-confirmed COVID-19, who received care at the FEU of a general hospital in the city of Buenos Aires from May through August 2020. Bivariate and multivariate analyses of sociodemographic and clinical variables were performed to build and internally validate a pneumonia predictive score.


The final analysis included 936 patients; 17.6% had ultrasound compatible with pneumonia. The score included 5 statistically significant variables: age ≥50 years (3 points), cough (2 points), absence of odynophagia (1 point), dyspnea (2 points) and oxygen saturation ≤95% (3 points). A cut-off point ≥3 showed a sensitivity of 80.5% and a negative predictive value of 93.3%, with good discriminatory capacity both in derivation and validation cohorts (area under ROC curve 0.79 and 0.76, respectively).


This score could be a useful tool to stratify the clinical risk of pneumonia in the pre-hospital setting and avoid imaging studies with a score <3.
