Association of Clinician Knowledge and Statin Beliefs With Statin Therapy Use and Lipid Levels (A Survey of US Practice in the PALM Registry).

ABSTRACT: Guideline implementation requires clinician knowledge but may be influenced by pre-existing beliefs and biases. We assessed the association of these clinician factors with lipid management following the release of the 2013 American College of Cardiology/American Heart Association cholesterol guidelines. In the PALM registry, 774 clinicians completed a survey to assess their knowledge of the 2013 American College of Cardiology/American Heart Association guidelines, belief in statin benefit, and statin safety concerns. The association of these factors with statin use, statin dosing, and low-density lipoprotein cholesterol (LDL-C) levels were assessed in the 6,839 patients treated by these clinicians between May and November 2015. Overall, 63.9% of clinicians responded to at least 3 out of 4 hypothetical scenarios in concordance with guideline recommendations (good tested knowledge), 88.4% reported belief in statin benefit, and 15.4% raised concerns about statin safety. Belief in statin benefit was more prevalent among cardiologists, who represented 48.8% of the clinicians surveyed, and concerns regarding statin safety were higher among noncardiologists and clinicians in an academic setting. Guideline knowledge was not associated with a difference in statin use (74.1% vs 73.8%, p?=?0.84) and achievement of LDL-C level <100 mg/dl (54.7% vs 52.4%, p?=?0.07). However, patients treated by clinicians who reported belief in statin benefit were more likely to receive guideline-recommended statin intensity (41.9% vs 36.9%, p?=?0.03), whereas patients treated by clinicians expressing statin safety concerns were less likely receive statins of at least guideline-recommended intensity (36.8% vs 42.5%, p?=?0.001) and to achieve an LDL-C <100 mg/dl (44.1% vs 56.1%, p <0.001); the latter persisted after multivariable adjustment (odds ratio 0.75, 95% confidence interval 0.63 to 0.89). In conclusion, clinician beliefs regarding benefits and risks of statins were significantly associated with guideline adherence and patients' achieved LDL-C levels, whereas clinician knowledge of guideline recommendations was not.

Project description:ImportanceAfrican American individuals face higher atherosclerotic cardiovascular disease risk than white individuals; reasons for these differences, including potential differences in patient beliefs regarding preventive care, remain unknown.ObjectiveTo evaluate differences in statin use between white and African American patients and identify the potential causes for any observed differences.Design, setting, and participantsUsing the 2015 Patient and Provider Assessment of Lipid Management (PALM) Registry data, we compared statin use and dosing between African American and white outpatient adults who were potentially eligible for primary or secondary prevention statins. A total of 138 US community health care practices contributed to the data. Data analysis was conducted from March 2017 to May 2018.Main outcomes and measuresPrimary outcomes were use and dosing of statin therapy according to the 2013 American College of Cardiology/American Heart Association guideline by African American or white race. Secondary outcomes included lipid levels and patient-reported beliefs. Poisson regression was used to evaluate the association between race and statin undertreatment, a category combining people who were not taking a statin or those taking a dose intensity lower than recommended.ResultsA total of 5689 patients (806 [14.2%] African American) in the PALM registry were eligible for statin therapy. African American individuals were less likely than white individuals to be treated with a statin (570/807 [70.6%] vs 3654/4883 [74.8%]; P = .02). Among those treated, African American patients were less likely than white patients to receive a statin at guideline-recommended intensity (269 [33.3%] vs 2145 [43.9%], respectively; P < .001; relative risk, 1.07 [95% CI, 1.00-1.15]; P = .05, after adjustment for demographic and clinical factors). The median (interquartile range) low-density lipoprotein cholesterol levels of patients receiving treatment were higher among African American than white individuals (97.0 [76.0-121.0] mg/dL vs 85.0 [68.0-105.0] mg/dL; P < .001). African American individuals were less likely than white individuals to believe statins were safe (292 [36.2%] vs 2800 [57.3%]; P < .001) or effective (564 [70.0%] vs 3635 [74.4%]; P = .008) and were less likely to trust their clinician (663 [82.3%] vs 4579 [93.8%]; P < .001). Group differences in statin undertreatment were not significant after adjusting for demographic, clinical, and clinician factors, socioeconomic status, and patient beliefs (final adjusted relative risk, 1.03 [95% CI 0.96-1.11]; P = .35).Conclusions and relevanceAfrican American individuals were less likely to receive guideline-recommended statin therapy. Demographic, clinical, socioeconomic, belief-related, and clinician differences contributed to observed differences and represent potential targets for intervention.
