Inter-rater reliability and prognostic value of baseline Radiographic Assessment of Lung Edema (RALE) scores in observational cohort studies of inpatients with COVID-19.

ABSTRACT:

Objectives

To reliably quantify the radiographic severity of COVID-19 pneumonia with the Radiographic Assessment of Lung Edema (RALE) score on clinical chest X-rays among inpatients and examine the prognostic value of baseline RALE scores on COVID-19 clinical outcomes.

Setting

Hospitalised patients with COVID-19 in dedicated wards and intensive care units from two different hospital systems.

Participants

425 patients with COVID-19 in a discovery data set and 415 patients in a validation data set.

Primary and secondary outcomes

We measured inter-rater reliability for RALE score annotations by different reviewers and examined for associations of consensus RALE scores with the level of respiratory support, demographics, physiologic variables, applied therapies, pl
