To measure case detection and response time of severe pediatric dyslipidemia, defined as non-high-density lipoprotein cholesterol (HDL-C) ≥190mg/dL on the initial screening panel. Although low adherence to guidelines recommending universal pediatric lipid screening is well-documented, it is unknown how clinicians respond to pediatric lipid screening results suggestive of severe dyslipidemia. This study is a single-institution, retrospective review of patients 0-18years of age with initial lipid panels completed from January 1, 2010, to June 30, 2018. A chart review was conducted on all patients with non-HDL-C ≥190mg/dL to determine indication(s) for the initial lipid panel, specialty of ordering clinician, type of action taken to an abnormal result (repeat laboratory tests, treatment, and/or referral), time from result to clinician action, and diagnosis. There were 16 860 initial lipid panels that met the inclusion criteria; 178 (1.1%) had non-HDL-C ≥190mg/dL, indicating severe dyslipidemia. The most common indication for screening was universal screening (52%). Forall lipid panels with non-HDL ≥190mg/dL, a clinician action was documented for 47% within 7days and 69% within30days. No follow-up action was documented in 18 (9%). A clinical diagnosis of familial hypercholesterolemia was the most common diagnosis, in 24% of patients. The majority of lipid panels with non-HDL-C ≥190mg/dL had some action documented, although the actions varied. Universal screening was the most common indication for testing, clarifying its significance in identifying severe dyslipidemia. Further education and improved management protocols may help responses to severe dyslipidemia in children at high risk for premature cardiovascular disease.
