Dotiwala Z, Casciano J, Davis JR, et al. - Utilizing data from EMRClaims + database, researchers assessed health care resource use in asthma patients with high blood eosinophil counts defined at 150 cells/μL or greater and 300 cells/μL or greater. If any test result during 3 months prior to follow-up revealed blood eosinophil count of 150 cells/μL or more or 300 cells/μL or more, then the patients were defined as having high eosinophil counts. Of 3,687 patients who were eligible, a test within 3 months prior to the follow-up period was received by 1,152, of whom 644 (56%) were found to have high eosinophil counts of 150 cells/μL or greater and 322 (29%) exhibited eosinophil counts of 300 cells/μL or greater. Findings revealed a greater health care resource use (number of hospitalizations and expenses) among patients with asthma in relation to their blood eosinophil counts elevated at 150 cells/μL or greater and 300 cells/μL or greater as measured within 3 months of follow-up.
