ABSTRACT
BACKGROUND:
We assessed the impact of optimal dyslipidemia control on mortality and costs in adults at high risk for cardiovascular disease (HRCVD).METHODS:
We linked Alberta health databases to identify patients aged ≥ 18 years with HRCVD between April 2012 and March 2017. The first HRCVD event was considered the index event. Patients were categorized into (1) optimal control and (2) suboptimal control of dyslipidemia based on biomarkers and lipid-lowering therapy during the year post-index event. We measured the association between optimal dyslipidemia control and mortality and health care costs using difference-in-difference and propensity score-matching methods.RESULTS:
The study included 459,739 patients with HRCVD (43,776 [9.5%] optimal patients). The optimal patients were older (median age = 62 vs 55 years; P < 0.001), included fewer female patients (37.7% vs 52%; P < 0.001), and featured a higher proportion of secondary prevention patients (15.7% vs 1.7%; P < 0.001). Compared with suboptimal patients, the optimal patients had lower adjusted mortality (0.7% vs 1.9% at 1-year and 2.9% vs 5.1% at 3-year post-index event; both P < 0.001), and higher adjusted health care costs (CA$3758 and CA$6844 at 1-year and 3-year post-index event, respectively; both P < 0.001). Among the secondary prevention group, the optimal patients had lower adjusted mortality (2.4% and 5% absolute reduction at 1-year and 3-year post-index event, respectively; both P < 0.001) at no additional costs. The results were robust across 5 definitions of optimal dyslipidemia control.CONCLUSIONS:
Patients with optimal dyslipidemia control have lower mortality and incur modestly higher costs. However, secondary prevention patients experience lower mortality at no additional costs.
