Statin prescribing patterns in patient-centered medical home patients with NAFLD

Cardiovascular disease is the leading cause of mortality in patients with nonalcoholic fatty liver disease (NAFLD), and statins play a pivotal role in the primary prevention of cardiovascular events. This study investigates statin prescribing in primary care patients with NAFLD to identify opportunities to address cardiovascular disease risk in this cohort.

Retrospective cohort study of primary care electronic health record data from 2012-2018.

This cohort included 652 patients with radiographic evidence of hepatic steatosis and no evidence of competing chronic liver disease. A statin prescription identified at any time during the study period was the primary outcome. Univariate and multivariable analyses were performed to evaluate the association of clinical signals and comorbidities with statin prescribing.

Of the 652 patients in the NAFLD cohort, 56% received a statin prescription during the study period. Elevations in aminotransferases were not associated with statin prescribing (adjusted odds ratio [AOR], 1.17; 95% CI, 0.78-1.76), whereas older patients (AOR, 1.06; 95% CI, 1.05-1.08) and those with diabetes (AOR, 2.61; 95% CI, 1.73-3.92), hypertension (AOR, 2.76; 95% CI, 1.70-4.48), and a BMI greater than or equal to 30 kg/m2 (AOR, 1.49; 95% CI, 1.01-2.22) had higher odds of having a statin prescribed. Of the 288 patients without a statin prescription, 49% had an indication for statin therapy by atherosclerotic cardiovascular disease risk. In total, 16% of included patients did not have lipid panel results during the study period.

This study showed no association between NAFLD and statin prescribing, and the findings highlight opportunities to improve primary prevention of cardiovascular disease in these at-risk patients.
