Prevalence and morbidity of primary immunodeficiency diseases, United States 2001-2007.

ABSTRACT:

Purpose

Few studies have estimated population prevalence and morbidity of primary immunodeficiency diseases (PIDD). We used administrative healthcare databases to estimate the prevalence of PIDD diagnoses in the United States from 2001 to 2007.

Methods

MarketScan databases compile claims from commercial health insurance plans and Medicaid, recording individual diagnoses for outpatient encounters and hospital stays. We used a cross sectional survey to estimate prevalence of PIDD using related ICD-9 codes (279.0, 279.1, 279.2, 279.8, 279.9, 288.1 and 288.2). Persons with secondary immunodeficiency diagnoses were excluded from analysis.

Results
