Abstract 369: Secondary Risk Reduction in Patients With Type 2 Diabetes and Cardiovascular Disease: Experience From a Cardiometabolic Center of Excellence

Background: Optimal guideline-directed medical therapy is delivered to only 6.9% of patients with type 2 diabetes (T2D) and cardiovascular disease (CVD) nationally, despite guideline recommendations emphasizing aggressive comprehensive secondary risk reduction. While there are many potential explanations, lack of effective clinical care delivery models is a key contributor. The Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute was designed to address this unmet need, by delivering a patient-centric, collaborative model of care which focuses on aggressive and comprehensive secondary risk reduction in patients with T2D and CVD. Patients are managed by a multidisciplinary team comprised of preventative cardiologists, advanced practice providers and nurses cross-trained in T2D and CVD management, certified diabetes educator, dietician, pharmacist, and other professionals, in close coordination with endocrinologists and primary care clinicians. We aimed to determine whether patients receiving care in the Center had experienced better intermediate outcomes with similar patients receiving routine care in conventional settings.

Methods: We analyzed data from the initial 60 patients seen in the Center who had at least one follow-up visit, and propensity matched them 1:3 to similar patients with T2D and CVD treated in conventional care settings. Propensity model included age, sex, baseline weight, HbA1c, systolic blood pressure (SBP), history of CVD, and duration between visits. Linear mixed models with a random effect for matched groups was used to compare between-group differences for changes in weight, LDL-C, and HbA1c.

Results: At baseline, patients in the Center weighed 241.3 lbs ± 51.0 and had HbA1c 7.4 ± 1.4 and LDL 68.0 ± 27.0 as compared to 245.5 lbs ± 55.3, HbA1c 7.5 ± 1.5, and LDL 79.1 ± 37.1 in controls. Average duration between follow up visits was 138.3 days ± 52.5 in patients seen in the Center and 138.9 days ± 54.7 in controls. Patients seen in the Center had greater degree of weight loss (12.3 lbs vs 3.8 lbs, p <0.001) and reduction in HbA1c (0.5 vs 0.0%, p = 0.04) and LDL-C (-8.4 vs +4.0 mg/dL, p = 0.04) as compared with controls. Patients receiving care at the Center were more likely to be treated with an SGLT-2i (70.0% [42/60] vs 22.8% [41/180], p<0.001) and/or a GLP-1RA (91.7% [55/60] vs 15.6% [28/180], p<0.001) than those in the standard of care cohort.

Conclusion: Patients with T2D and CVD, seen in a specialized, comprehensive Cardiometabolic Center experienced higher use of guideline-directed medical therapies and greater reduction in multiple CVD risk factors within ~4 months, as compared to those seen in the conventional setting. Although longer follow up is needed, these preliminary data suggest that such novel clinical care delivery models may improve the implementation of clinical practice guidelines.
