A secondary prevention lipid clinic reaches low-density lipoprotein cholesterol goals more often than usual cardiology care with coronary heart disease

Implementation and Outcomes of Multidisciplinary Diabetes Management Program Among Type 2 Diabetic Patients: A Comparative Study

BACKGROUND

Current guidelines recommend shifting physician-led care (PLC) for type 2 diabetes mellitus (T2DM) to more effective multidisciplinary health care (MHC). However, few researchers have studied its real-life implementation in Saudi Arabia. Therefore, we aimed to assess the implementation and compare the outcomes of an MDC diabetes management program (DMP) among T2DM patients to a PLC at a general hospital after one year of follow-up in a real-world practice setting.

METHODS

We conducted this comparative patient files review study by analyzing medical records of all T2DM patients at two private care centers. Both were compared for their effectiveness in achieving two outcomes: the glycated hemoglobin (HbA1c) <7% and low-density lipoprotein-cholesterol (LDL-c) <70 mg/dl at the end of the first year. Additionally, we assessed the implementation of the DMP.

RESULTS

Eight hundred thirty-four medical records were reviewed, 537 from DMP, and 279 from the PLC center. The personal health coordination was almost complete (97.8%) in the DMP, but the implementation was incomplete regarding nutrition (65.7%), dental exam (64.8%), and foot care (58.3%). Both care groups were matched for age (p = 0.056), gender (p = 0.085), duration of diabetes (p = 0.217), and basal glycemic control (p = 0.171). The DMP showed a significant net decrease in HbA1c (-0.5 [IQR 1.47%] vs -0.2 [IQR 3.05%], p = 0.0001) and LDL-c (-10 [IQR 50] vs -5 [IQR 60.5] mg/dl, p = 0.004) compared to PLC. A higher percentage of patients achieved glycemic control in the DMP than in the PLC (49.4% vs 38.7%, p = 0.038). However, both programs demonstrated similar outcomes in lipid control (28.7% vs. 30%, p = 0.695).

CONCLUSION

Despite some gaps in implementation, one year of DMP showed better glycemic control among T2DM patients compared to PLC. Both programs were comparable in terms of lipid control. Further studies identifying the gaps in care implementation could improve sustainability, future replication, and generalizability of similar programs to other healthcare systems in Saudi Arabia.

Impact of a preventive cardiology clinic focusing on lifestyle and nutrition counseling: A pilot analysis

Standard cardiology practice often defers preventive strategies to primary care providers. We aimed to evaluate the effectiveness of a preventive cardiology clinic focused on lifestyle and nutrition counseling combined with guideline-directed medical therapy on reducing cardiovascular disease (CVD) risk. We queried the University of Florida-Health database for patients enrolled in the preventive cardiology clinic, and a general and interventional cardiology clinic from January 2016 to October 2019. Mean change in weight and blood cholesterol including LDL cholesterol (LDL-C), total cholesterol (TC) and triglycerides (TG) were compared in the three clinics in the initial cohort and stratified into primary and secondary prevention. A propensity score-matched analysis was done to adjust for CVD risk factors and statin use. Among a cohort of 239 patients, enrollment in the preventive clinic (n = 99) was associated with greater weight loss at 6 months compared to other clinics (n = 140) (mean -1.7 vs +0.1 kg, p 0.007). Preventive clinic was also associated with greater mean reduction in LDL-C (-24.8 vs -7.1 mg/dl, p 0.021), TC (-29.3 vs -2.0, p 0.003) and TG (-19.7 vs +13.3, p 0.002) at both initial and last follow-up (median time 6 and 16 months). The association with reduction in TG was observed in both primary and secondary prevention, but reduction in LDL-C and TC was only significant in secondary prevention. In a propensity-matched linear regression analysis, preventive clinic was independently associated with LDL-C reduction (b -14.7, r -0.3, p 0.038). A preventive cardiology clinic focused on patient education can be effective in reducing CVD risk.

Evaluation of a multidisciplinary lipid clinic to improve the care of individuals with severe lipid conditions: a RE-AIM framework analysis

BACKGROUND

Individuals with complex dyslipidemia, or those with medication intolerance, are often difficult to manage in primary care. They require the additional attention, expertise, and adherence counseling that occurs in multidisciplinary lipid clinics (MDLCs). We conducted a program evaluation of the first year of a newly implemented MDLC utilizing the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework to provide empirical data not only on program effectiveness, but also on components important to local sustainability and future generalizability.

METHODS

The purpose of the MDLC is to increase the uptake of guideline-based care for lipid conditions. Established in 2019, the MDLC provides care via a centralized clinic location within the healthcare system. Primary care providers and cardiologists were invited to refer individuals with lipid conditions. Using a pre/post-study design, we evaluated the implementation outcomes from the MDLC using the RE-AIM framework.

RESULTS

In 2019, 420 referrals were made to the MDLC (reach). Referrals were made by 19% (148) of the 796 active cardiology and primary care providers, with an average of 35 patient referrals per month in 2019 (SD 12) (adoption). The MDLC saw 83 patients in 2019 (reach). Additionally, 50% (41/82) had at least one follow-up MDLC visit, and 12% (10/82) had two or more follow-up visits in 2019 (implementation). In patients seen by the MDLC, we found an improved diagnosis of specific lipid conditions (FH (familial hypercholesterolemia), hypertriglyceridemia, and dyslipidemia), increased prescribing of evidence-based therapies, high rates of medication prior authorization approvals, and significant reductions in lipid levels by lipid condition subgroup (effectiveness). Over time, the operations team decided to transition from in-person follow-up to telehealth appointments to increase capacity and sustain the clinic (maintenance).

CONCLUSIONS

Despite limited reach and adoption of the MDLC, we found a large intervention effect that included improved diagnosis, increased prescribing of guideline-recommended treatments, and clinically significant reduction of lipid levels. Attention to factors including solutions to decrease the large burden of unseen referrals, discussion of the appropriate number and duration of visits, and sustainability of the clinic model could aid in enhancing the success of the MDLC and improving outcomes for more patients throughout the system.

PCSK9 Inhibitors

Objective: To evaluate the safety and efficacy of 2 human monoclonal antibodies, alirocumab and evolocumab, on reduction of low-density lipoprotein cholesterol (LDL-C), cardiovascular benefits, and their place in current practice. Data Sources: A search of MEDLINE and Scopus databases (1966 to May 2016) with search terms “alirocumab,” “evolocumab,” “LDL,” and “PCSK9.” Study Selection and Data Extraction: The search identified phase 3 randomized control trials in English language in the past 10 years that studied LDL-C reduction of alirocumab or evolocumab. The studies were assessed for all efficacy and safety endpoints. Data Synthesis: Twelve total studies were identified evaluating alirocumab or evolocumab. These monoclonal antibodies have been shown to significantly decrease LDL-C as monotherapy and in combination with statins in phase 3 clinical trials in patients with primary hypercholesterolemia as well as familial hypercholesterolemia by inhibiting PCSK9. Alirocumab significantly reduced LDL-C by up to 61%, while evolocumab significantly reduced LDL-C by up to 66%. Adverse effects of these medications have been low and overall well tolerated. Conclusion: Although these monoclonal antibodies have shown to significantly reduce LDL-C, their effect on cardiovascular outcomes has not yet been determined. Further studies are being conducted to assess the cardiovascular benefit of both alirocumab and evolocumab. Until these studies demonstrate a reduction in atherosclerotic cardiovascular disease risk, statins should remain first-line therapy for most patients. However, alirocumab and evolocumab can be used as an effective adjunctive therapy option to lower LDL-C or in patients who are statin intolerant.

The role of the clinical pharmacist in the care of patients with cardiovascular disease

Team-based cardiovascular care, including the use of clinical pharmacists, can efficiently deliver high-quality care. This Joint Council Perspectives paper from the Cardiovascular Team and Prevention Councils of the American College of Cardiology provides background information on the clinical pharmacist's role, training, certification, and potential utilization in a variety of practice models. Selected systematic reviews and meta-analyses, highlighting the benefit of clinical pharmacy services, are summarized. Clinical pharmacists have a substantial effect in a wide variety of roles in inpatient and ambulatory settings, largely through optimization of drug use, avoidance of adverse drug events, and transitional care activities focusing on medication reconciliation and patient education. Expansion of clinical pharmacy services is often impeded by policy, legislation, and compensation barriers. Multidisciplinary organizations, including the American College of Cardiology, should support efforts to overcome these barriers, allowing pharmacists to deliver high-quality patient care to the full extent of their education and training.
