RSV testing practice and positivity by patient demographics in the United States: integrated analyses of MarketScan and NREVSS databases.

ABSTRACT:

Background

RSV-incidence estimates obtained from routinely-collected healthcare data (e.g., MarketScan) are commonly adjusted for under-reporting using test positivity reported in national Surveillance Systems (NREVSS). However, NREVSS lacks detail on patient-level characteristics and the validity of applying a single positivity estimate across diverse patient groups is uncertain. We aimed to describe testing practices and test positivity across subgroups of private health insurance enrollees in the US and illustrate the possible magnitude of misclassification when using NREVSS to correct for RSV under ascertainment.

Methods

Using billing records, we determined distributions of RSV-test claims and test positivity among a national sample of private insurance enrollees. Tests
