National Trends in Nonstatin Use and Expenditures Among the US Adult Population From 2002 to 2013: Insights From Medical Expenditure Panel Survey

Abstract

Background

Evidence supporting nonstatin lipid‐lowering therapy in atherosclerotic cardiovascular disease risk reduction is variable. We aim to examine nonstatin utilization and expenditures in the United States between 2002 and 2013.

Methods and Results

We used the Medical Expenditure Panel Survey database to estimate national trends in nonstatin use and cost (total and out‐of‐pocket, adjusted to 2013 US dollars using a gross domestic product deflator) among adults 40 years or older. Nonstatin users increased from 3 million (2.5%) in 2002‐2003 (20.1 million prescriptions) to 8 million (5.6%) in 2012‐2013 (45.8 million prescriptions). Among adults with atherosclerotic cardiovascular disease, nonstatin use increased from 7.5% in 2002‐2003 to 13.9% in 2012‐2013 after peaking at 20.3% in 2006‐2007. In 2012‐2013, 15.9% of high‐intensity statin users also used nonstatins, versus 9.7% of low/moderate‐intensity users and 3.6% of statin nonusers. Nonstatin use was significantly lower among women (odds ratio 0.80; 95% confidence interval 0.75‐0.86), racial/ethnic minorities (odds ratio 0.41; 95% confidence interval 0.36‐0.47), and the uninsured (odds ratio 0.47; 95% confidence interval 0.40‐0.56). Total nonstatin expenditures increased from $1.7 billion (out‐of‐pocket cost, $0.7 billion) in 2002‐2003 to $7.9 billion (out‐of‐pocket cost $1.6 billion) in 2012‐2013, as per‐user nonstatin expenditure increased from $550 to $992. Nonstatin expenditure as a proportion of all lipid‐lowering therapy expenditure increased 4‐fold from 8% to 32%.

Conclusions

Between 2002 and 2013, nonstatin use increased by 124%, resulting in a 364% increase in nonstatin‐associated expenditures.
