RESUMEN
Objective: National guidelines recommend statin therapy for patients with type 2 diabetes. We assessed the extent of moderate- to high-intensity statin therapy utilization in community practice. Methods: We evaluated lipid-lowering therapy (LLT) and low-density lipoprotein cholesterol (LDL-C) levels at baseline and 1-year follow-up in patients aged 40-75 years with type 2 diabetes but without atherosclerotic cardiovascular disease (ASCVD), across 90 health systems in the United States participating in an electronic health record-derived dataset, Cerner Real-World Data. Multivariable logistic regression was used to evaluate factors associated with utilization of moderate- to high-intensity statin. Results: We identified 241,232 patients with type 2 diabetes (58.1â¯% on moderate- to high-intensity statin, 7.0â¯% on low-intensity statin, and 34.9â¯% on no statin). Predictors of moderate- to high-intensity statin therapy included retinopathy (adjusted odds ratio [aOR], 1.26; 95â¯% confidence interval [CI], 1.15-1.38), hypertension (aOR, 1.52; 95â¯% CI, 1.43-1.61), and stage 3 chronic kidney disease (aOR, 1.14; 95â¯% CI, 1.07-1.21). Women (aOR, 0.85; 95â¯% CI, 0.82-0.87), and those with rheumatoid arthritis (aOR, 0.79; 95â¯% CI, 0.71-0.87), psoriasis (aOR, 0.85; 95â¯% CI, 0.75-0.96), and hepatitis C (aOR, 0.40; 95â¯% CI, 0.39-0.46), had reduced odds of moderate- to high-intensity statin treatment. Utilization of ezetimibe was rare (2.0â¯%). LDL-C control was suboptimal at baseline (37.0â¯% and 27.9â¯% had LDL-C ≥100 mg/dL and <70 mg/dL, respectively). At 1-year follow-up, the rate of moderate- to high-intensity statin therapy utilization was 65.3â¯%. Conclusion: Increased efforts are needed to improve LDL-C control and LLT use for primary prevention of ASCVD in adults with type 2 diabetes, in particular among women and those with risk-enhancing inflammatory conditions.
RESUMEN
BACKGROUND: Cardiovascular disease remains the leading cause of death in adults in the United States and constitutes a substantial portion of overall national health expenditures. Aspirin is generally recommended for primary cardiovascular event prevention based on a given patient's underlying cardiovascular event risk profile, particularly for those aged 50-69 years with a 10-year risk of coronary heart disease of ≥ 10%. Evidence-based clinical guidelines are in agreement for secondary prevention consisting of lifelong, low-dose aspirin therapy following a cardiovascular event. Despite these recommendations, research suggests suboptimal concordance between guidelines and clinical practice. OBJECTIVE: To evaluate the budget impact of appropriate low-dose aspirin use for primary and secondary cardiovascular event prevention compared with current rates of low-dose aspirin use. METHODS: An economic model measuring budget spend for cardiovascular events, aspirin, and aspirin-related adverse events was developed from the perspective of a U.S. payer. The model compared current rates of aspirin use to appropriate rates of aspirin use according to guideline recommendations for both primary and secondary cardiovascular event prevention. RESULTS: For a hypothetical plan with 1 million members, an estimated 18,026 patients were on aspirin therapy for primary cardiovascular event prevention, while guidelines recommend that 55,788 patients should have been on aspirin therapy for this indication. Optimal aspirin use in the primary cardiovascular event prevention population reduced the number of nonfatal myocardial infarctions (MIs; -367), ischemic strokes (-232), and deaths (-60), with an increase in the number of gastrointestinal bleeds (169) and hemorrhagic strokes (98). Evidence-based guideline-compliant use of aspirin for primary cardiovascular event prevention resulted in total cost savings of approximately $4.2 million over a 5-year time horizon. For secondary cardiovascular event prevention, an estimated 48,663 patients were on aspirin, while clinical guidelines recommend that 71,316 patients should have been on aspirin therapy for this indication. Optimal aspirin use in secondary cardiovascular event prevention reduced the number of nonfatal MIs (-515), ischemic strokes (-375), and deaths (-217), with an increase in the number of gastrointestinal bleeds (98) and hemorrhagic strokes (58). Evidence-based guideline-compliant use of aspirin for secondary cardiovascular event prevention resulted in total cost savings of approximately $11 million over a 5-year time horizon. CONCLUSIONS: Appropriate low-dose aspirin use for primary and secondary cardiovascular event prevention can result in improved patient outcomes with significant cost savings for U.S. payers. As a simple and inexpensive prophylactic measure for cardiovascular event prevention, aspirin use should be carefully considered in all appropriate at-risk adult patients.
