Clinical and economic outcomes in a real-world population of patients with elevated triglyceride levels.

Abstract Objective : This study investigated real-world treatment patterns, healthcare utilization, and costs of hypertriglyceridemia in a large commercially insured United States population. Methods : This observational claims study was conducted among adult patients with TG > 500 mg/dL between 01/01/2007 and 04/30/2013. Patients were stratified into mutually exclusive cohorts based on their first available TG measurement (index date): TG ≥ 1500 (Cohort A); 750 ≤ TG  Results : We identified a total of 1964 patients in Cohort A, 7432 in Cohort B, and 17,500 in Cohort C. Patients were young (mean age 46–48) and mostly male (75%–80%). Treatment switching and augmentation occurred rarely, and almost 50% of patients discontinued their initial treatment. At baseline, healthcare utilization and costs were highest in Cohort A (mean all-cause medical and pharmacy costs, $8850). At follow-up, the number of patients with dyslipidemia-related office and pharmacy claims and related costs almost doubled across the cohorts. Mean all-cause costs/patient in Cohort A at follow-up were $12,642, of which $3730 were dyslipidemia-related. Acute pancreatitis episodes were associated with >300% increase in total all-cause costs in Cohort A. Conclusions : These results suggest that severe hypertriglyceridemia is undertreated and healthcare utilization and costs scale with magnitude of TG elevation. Patients with more severe hypertriglyceridemia received greater medical and pharmacy services. Managing severe hypertriglyceridemia more aggressively and preventing acute pancreatitis may generate cost savings.
