摘要

Purpose To examine the rate of lipid testing among children from a large US medical insurance claims database, describe the characteristics of pediatric dyslipidemia, and assess the sensitivity of the International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes for identifying dyslipidemic children.
Methods This retrospective cohort study used the claims data from the Integrated Healthcare Information Services (IHCIS), for the years 2003-2006. Two study cohorts consisted of children with laboratory-defined and diagnosis/treatment-defined dyslipidemia, respectively. They were compared to age- and gender-matched children without dyslipidemia, with respect to co-morbidities during the 6-month prior to and 12-month after the first dyslipidemic laboratory value or diagnosis/treatment.
Results Seven per cent of the children who had laboratory values available in the database had a cholesterol test during the study period. Only 15% of laboratory-defined children (n = 23 475) had a dyslipidemia diagnosis. Cholesterol-modifying medications were rarely prescribed. Substantially more laboratory-defined children than their comparators were obese (8 times), had diabetes mellitus (10 times), or had hypertension (5 times). These co-morbidities were even higher among diagnosis/treatment-defined children.
Conclusions The rate of lipid testing among children was low. The ICD-9-CM diagnostic codes showed low sensitivity against laboratory definitions. Though only a small proportion of dyslipidemic children were diagnosed or treated with a medication, co-morbidities associated with dyslipidemia were common.
