COVID-19 severity scale for claims data research.

ABSTRACT:

Objective

To create and validate a methodology to assign a severity level to an episode of COVID-19 for retrospective analysis in claims data.

Data source

Secondary data obtained by license agreement from Optum provided claims records nationally for 19,761,754 persons, of which, 692,094 persons had COVID-19 in 2020.

Study design

The World Health Organization (WHO) COVID-19 Progression Scale was used as a model to identify endpoints as measures of episode severity within claims data. Endpoints used included symptoms, respiratory status, progression to levels of treatment and mortality.

Data collection/extraction methods

The strategy for identification of cases relied upon the February 2020 guidance from the Centers for Disease Control and Prevention (CDC).
