RESUMO

This study aims to explore the pharmacological substance basis of Qi Ge Decoction (QG) in antihyperlipidemia through a combination of metabolomics and serum pharmacochemistry. We used ultra-performance liquid chromatography quadrupole-time-of-flight/MS (UPLC Q-TOF/MS) to analyze and identify the chemical constituents of QG in vitro and in blood chemical components. The metabolomics technology was used to analyze serum biomarkers of QG in preventing and treating hyperlipidemia. We constructed a mathematical model of the relationship between constituents absorbed into the blood and endogenous biomarkers and explored the potential therapeutic application of QG for the prevention and treatment of hyperlipidemia. Compared with the model group, the levels of total cholesterol and triglyceride in the QG group were significantly decreased (P < 0.01). A total of 12 chemical components absorbed into the blood were identified, and 48 biomarkers of the hyperlipidemia model were obtained from serum metabolomic analysis, of which 15 metabolites were backregulated after QG intervention. Puerarin, hesperetin, puerarin xyloside, calycosin, and monohydroxy-tetramethoxyflavone had a high correlation with the biomarkers regulated by QG. This study elucidated the material basis of QG in the intervention of hyperlipidemia, thereby facilitating future research aimed at further revealing the pharmacodynamic material basis of QG's antihyperlipidemic effects.

RESUMO

OBJECTIVES: India has taken several initiatives to provide health care to its population while keeping the related expenditure minimum. Since cardiovascular diseases are the most prevalent chronic conditions, in the present study, we aimed to analyze the difference in prices of medicines prescribed for three cardiovascular risk factors, based on (a) listed and not listed in the National List of Essential Medicines (NLEM) and (b) generic and branded drugs. MATERIALS AND METHODS: Outpatient prescriptions for diabetes mellitus, hypertension, and dyslipidemia were retrospectively analyzed from 12 tertiary centers. The prices of medicines prescribed were compared based on presence or absence in NLEM India-2015 and prescribing by generic versus brand name. The price was standardized and presented as average price per medicine per year for a given medicine. The results are presented in Indian rupee (INR) and as median (range). RESULTS: Of the 4,736 prescriptions collected, 843 contained oral antidiabetic, antihypertensive, and/or hypolipidemic medicines. The price per medicine per year for NLEM oral antidiabetics was INR 2849 (2593-3104) and for non-NLEM was INR 5343 (2964-14364). It was INR 806 (243-2132) for generic and INR 3809 (1968-14364) for branded antidiabetics. Antihypertensives and hypolipidemics followed the trend. The price of branded non-NLEM medicines was 5-22 times higher compared to generic NLEM which, for a population of 1.37 billion, would translate to a potential saving of 346.8 billion INR for statins. The variability was significant for sulfonylureas, angiotensin receptor blockers, beta-blockers, diuretics, and statins (P < 0.0001). CONCLUSION: The study highlights an urgent need for intervention to actualize the maximum benefit of government policies and minimize the out-of-pocket expenditure on medicines.

RESUMO

BACKGROUND: Although lipid-lowering drugs are not recommended for primary prevention in patients 75+, prevalence of use is high and there is unexplained variation in prescribing between physicians. The objective of this study was to determine if physician communication ability and clinical competence are associated with prescribing lipid-lowering drugs for primary and secondary prevention. METHODS: We used a cohort of 4,501 international medical graduates, 161,214 U.S. Medicare patients with hyperlipidemia (primary prevention) and 49,780 patients with a history of cardiovascular disease (secondary prevention) not treated with lipid-lowering therapy who were seen by study physicians in ambulatory care. Clinical competence and communication ability were measured by the ECFMG clinical assessment examination. Physician citizenship, age, gender, specialty and patient characteristics were also measured. The outcome was an incident prescription of lipid-lowering drug, evaluated using multivariable GEE logistic regression models for primary and secondary prevention for patients 75+ and 65-74. RESULTS: Patients 75+ were less likely than those 65-74 to receive lipid-lowering drugs for primary (OR 0.62, 95% CI 0.59-0.66) and secondary (OR 0.70, 95% CI 0.63-0.78) prevention. For every 20% increase in clinical competence score, the odds of prescribing therapy for primary prevention to patients 75+ increased by 24% (95% CI 1.02-1.5). Communication ability had the opposite effect, reducing the odds of prescribing for primary prevention by 11% per 20% score increase (95% CI 0.8-0.99) for both age groups. Physicians who were citizens of countries with higher proportions of Hispanic (South/Central America) or Asian (Asia/Oceania) people were more likely to prescribe treatment for primary prevention, and internal medicine specialists were more likely to treat for secondary prevention than primary care physicians. CONCLUSION: Clinical competence, communication ability and physician citizenship are associated with lipid-lowering drug prescribing for primary prevention in patients aged 75+.

RESUMO

BACKGROUND: Individuals diagnosed with and treated for type 1 diabetes (T1D) have increased risk of micro- and macrovascular disease and excess mortality. Improving cardiovascular (CV) risk factors in individuals with T1D is known to reduce diabetes- related CV complications. AIM: To examine time trends in CV risk factor levels and CV-protective treatment patterns. Additionally, examine incidence rates of diabetes-related CV complications in relation to exposure CV-protective treatment. METHODS: We analysed records from 41,630 individuals with T1D, registered anytime between 1996 and 2017 in a nationwide diabetes register. We obtained CV risk factor measurements (2010-2017), CV-protective drug profiles (1996-2017) and CV complication history (1977-2017) from additional nationwide health registers. RESULTS: From 2010 to 2017 there were decreasing levels of HbA1c, LDL-C, and blood pressure. Decreasing proportion of smokers, individuals with glycaemic dysregulation (HbA1c ≥ 58 mmol/mol), dyslipidaemia (LDL-C > 2.6 mmol/l), and hypertension (≥ 140/85 mmHg). Yet, one fifth of the T1D population by January 1st, 2017 was severely dysregulated (HbA1c > 75 mmol/mol). A slight increase in levels of BMI and urinary albumin creatinine ratio and a slight decrease in estimated glomerular filtration rate (eGFR) levels was observed. By January 1st, 2017, one fourth of the T1D population had an eGFR < 60 ml/min/1.73 m2. The proportion of the T1D population redeeming lipid-lowering drugs (LLDs) increased from 5% in 2000 to 30% in 2010 followed by a plateau and then a decline. The proportion of the T1D population redeeming antihypertensive drugs (AHDs) increased from 28% in 1996 to 42% in 2010 followed by a tendency to decline. Use of LLDs was associated with lower incidence of micro- and macrovascular complications, while use of AHDs had higher incidence of CVD and CKD, when compared to non-use and discontinued use, respectively. CONCLUSION: Improvements were seen in CV risk factor control among individuals with T1D in Denmark between 2010 and 2017. However, there is clearly a gap between current clinical guidelines and clinical practice for CV risk management in T1D. Action is needed to push further improvements in CV risk control to reduce CVD and the related excess mortality.

RESUMO

OBJECTIVE: To analyse utilisation patterns of lipid-lowering drugs and the related costs in Switzerland between the years 2013 and 2019. METHODS: We conducted a retrospective descriptive study using administrative claims data of persons aged ≥18 years enrolled with the health insurance company Helsana. To enable statements at the Swiss population level, results were extrapolated according to age, sex and canton of residence. RESULTS: The overall prevalence of patients taking lipid-lowering drugs rose from 8.9% (n = 736,174) in 2013 to 11.6% (n = 841,682) in 2019, but varied markedly across regions, with highest values in Ticino and lowest values in Zurich. More than every third individual aged ≥65 years was treated with a lipid-lowering drug in 2019. Statins were by far the most commonly used drugs (>90% of prescriptions), followed by ezetimibe, fibrates and PCSK9 inhibitors. We observed a trend towards the prescription of more potent statins (atorvastatin, rosuvastatin) in recent years. Total costs of lipid-lowering drugs increased from CHF 222 million in 2013 to CHF 230 million in 2019 (+3.5%), whereas annual per capita costs decreased from CHF 302 in 2013 to CHF 273 in 2019 (-9.4%). CONCLUSION: The increasing use of lipid-lowering drugs reflects current therapeutic guidelines, but results in high costs for the healthcare system.

RESUMO

OBJECTIVE: The aims of this study were to assess the incidence of major vascular events (MVE) and peripheral vascular events (PVE) in people with a small asymptomatic abdominal aortic aneurysm (AAA) and model the theoretical benefits and costs of an intensified low density lipoprotein cholesterol (LDL-C) lowering programme. METHODS: A total of 583 participants with AAAs measuring 30 - 54 mm were included in this study. The control of LDL-C and prescription of lipid lowering drugs were assessed by dividing participants into approximately equal tertiles depending on their year of recruitment into the study. The occurrence of MVE (myocardial infarction, stroke, cardiovascular death, and coronary or non-coronary revascularisation) and PVE (non-coronary revascularisation, AAA repair, and major amputation) were recorded prospectively, and the incidence of these events was calculated using Kaplan-Meier analysis. The relative risk reduction reported for these events in a previous randomised control trial (RCT) was then applied to these figures to model the absolute risk reduction and numbers needed to treat (NTT) that could theoretically be achieved with a mean LDL-C lowering of 1 mmol/L. The maximum allowable expense for a cost effective intensive LDL-C lowering programme was estimated using a cost utility analysis. RESULTS: At entry, only 28.5% of participants had an LDL-C of < 1.8 mmol/L and only 18.5% were prescribed a high potency statin (atorvastatin 80 mg or rosuvastatin 40 mg). The five year incidences of MVE and PVE were 38.1% and 44.7%, respectively. It was estimated that if the mean LDL-C of the cohort had been reduced by 1 mmol/L, this could have reduced the absolute risk of MVE and PVE by 6.5% (95% CI 4.4 - 8.7; NNT 15) and 5.3% (95% CI 1.4 - 7.5; NNT 19), respectively. It was estimated that the maximum allowable expense for a cost effective LDL-C lowering programme would be between $1 239 AUD (€768) and $1 582 AUD (€981) per person per annum over a five year period. CONCLUSION: People with a small asymptomatic AAA are at high risk of MVE and PVE. This study provides evidence of the possible benefits and allowable expense for a cost effective intensive LDL-C lowering programme in this population.

RESUMO

BACKGROUND: In the treatment of coronary heart disease, secondary prevention goals are still often unmet and poor adherence to prescribed drugs has been suggested as one of the reasons. We aimed to investigate whether pharmaceutical care by a pharmacist at the cardiology clinic trained in motivational interviewing improves clinical outcomes and patient adherence. METHODS: This was a prospective, randomized, controlled, outcomes-blinded trial designed to compare pharmaceutical care follow-up with standard care. After standard follow-up at the cardiology clinic, patients in the intervention group were seen by a clinical pharmacist two to five times as required over seven months. Pharmacists were trained to use motivational interviewing in the consultations and they tailored their support to each patient's clinical needs and beliefs about medicines. The primary study end-point was the proportion of patients who reached the treatment goal for low-density lipoprotein cholesterol by 12 months after discharge. The key secondary outcome was patient adherence to lipid-lowering therapy at 15 months after discharge, and other secondary outcomes were the effects on patient adherence to other preventive drugs, systolic blood pressure, disease-specific quality of life, and healthcare use. RESULTS: 316 patients were included. The proportion of patients who reached the target for low-density lipoprotein cholesterol were 37.0% in the intervention group and 44.2% in the control group (P = .263). More intervention than control patients were adherent to cholesterol-lowering drugs (88 vs 77%; P = .033) and aspirin (97 vs 91%; P = .036) but not to beta-blocking agents or renin-angiotensin-aldosterone system inhibitors. CONCLUSIONS: Our intervention had no positive effects on risk factors for CHD, but it increased patient adherence. Further investigation of the intervention process is needed to explore the difference in results between patient adherence and medication effects. Longer follow-up of healthcare use and mortality will determine if the increased adherence per se eventually will have a meaningful effect on patient health. TRIAL REGISTRATION: ClinicalTrials.gov NCT02102503, 03/04/2014 retrospectively registered.

RESUMO

OBJECTIVE: To assess how lipid-lowering drugs (LLDs) are administered in the hospitalized patients aged 65 and older and their association with clinical outcomes according to their health-related profiles. DESIGN: This is a retrospective study based on data from REPOSI (REgistro POliterapie SIMI - Italian Society of Internal Medicine) register, an Italian network of internal medicine hospital wards. SETTING AND PARTICIPANTS: A total of 4642 patients with a mean age of 79 years enrolled between 2010 and 2018. METHODS: Socio-demographic characteristics, functional abilities, cognitive skills, laboratory parameters and comorbidities were used to investigate the health state profiles by using multiple correspondence analysis and clustering. Logistic regression was used to assess whether LLD prescription was associated with patients' health state profiles and with short-term mortality. RESULTS: Four clusters of patients were identified according to their health state: two of them (Cluster III and IV) were the epitome of frailty conditions with poor short-term outcomes, whereas the others included healthier patients. The average prevalence of LLD use was 27.6%. The lowest prevalence was found among the healthier patients in Cluster I and among the oldest frail patients with severe functional and cognitive impairment in Cluster IV. The highest prevalence was among multimorbid patients in Cluster III (OR=4.50, 95% CI=3.76-5.38) characterized by a high cardiovascular risk. Being prescribed with LLDs was associated with a lower 3-month mortality, even after adjusting for cluster assignment (OR=0.59; 95% CI = 0.44-0.80). CONCLUSION: The prevalence of LLD prescription was low and in overall agreement with guideline recommendations and with respect to patients' health state profiles.

RESUMO

OBJECTIVE: To describe physicians' variation in de-adopting concurrent statin and fibrate therapy for type 2 diabetic patients following a reversal in clinical evidence. DATA SOURCES: We analyzed 2007-2015 claims data from OptumLabs® Data Warehouse, a longitudinal, real-world data asset with de-identified administrative claims and electronic health record data. STUDY DESIGN: We modeled fibrate use among Medicare Advantage and commercially insured type 2 diabetic statin users before and after the publication of the ACCORD lipid trial, which found statins and fibrates were no more effective than statins alone in reducing cardiovascular events among type 2 diabetic patients. We modeled fibrate use trends with physician random effects and physician characteristics such as age and specialty. DATA EXTRACTION: We identified patient-year-quarters with one year of continuous insurance enrollment, type 2 diabetes diagnoses, and fibrate use. We designated the physician most responsible for patients' diabetes care based on evaluation and management visits and prescriptions of glucose-lowering drugs. PRINCIPAL FINDINGS: Fibrate use increased by 0.12 percentage points per quarter among commercial patients (95% CI, 0.10 to 0.14) and 0.17 percentage points per quarter among Medicare Advantage patients (95% CI, 0.13 to 0.20) before the trial and then decreased by 0.16 percentage points per quarter among commercial patients (95% CI, -0.18 to -0.15) and 0.05 percentage points per quarter among Medicare Advantage patients (95% CI, -0.06 to -0.03) after the trial. However, 45% of physicians treating commercial patients and 48% of physicians treating Medicare Advantage patients had positive trends in prescribing following the trial. Physicians' characteristics did not explain their variation (pseudo R2  = 0.000). CONCLUSION: On average, physicians decreased fibrate prescribing following the ACCORD lipid trial. However, many physicians increased prescribing following the trial. Observable physician characteristics did not explain variations in prescribing. Future research should examine whether physicians vary similarly in other de-adoption settings.

RESUMO

Peripheral Artery Disease (PAD) is a manifestation of atherosclerosis characterized by diminished perfusion of the limb and a state of dysmetabolism. The asymptomatic PAD phenotype is a relatively recent classification. It is unknown how many people currently live with asymptomatic PAD because there are no universal screening recommendations for patients at risk for PAD. Patients with asymptomatic PAD suffer from a similar risk profile of morbidity and mortality as their counterparts with claudication. Despite this increased risk, there is a dearth of clinical investigations into therapies that specifically benefit the asymptomatic PAD population. At present, current pharmacotherapies that have been studied in PAD patient populations do not stratify by symptom status. We believe that further investigation of the impact of existing therapies in this unique population presents an opportunity to reduce morbidity and mortality due to PAD. This can only be achieved in combination with wide-spread adoption of screening for asymptomatic PAD.

RESUMO

BACKGROUND: We assessed the impact of optimal dyslipidemia control on mortality and costs in adults at high risk for cardiovascular disease (HRCVD). METHODS: We linked Alberta health databases to identify patients aged ≥ 18 years with HRCVD between April 2012 and March 2017. The first HRCVD event was considered the index event. Patients were categorized into (1) optimal control and (2) suboptimal control of dyslipidemia based on biomarkers and lipid-lowering therapy during the year post-index event. We measured the association between optimal dyslipidemia control and mortality and health care costs using difference-in-difference and propensity score-matching methods. RESULTS: The study included 459,739 patients with HRCVD (43,776 [9.5%] optimal patients). The optimal patients were older (median age = 62 vs 55 years; P < 0.001), included fewer female patients (37.7% vs 52%; P < 0.001), and featured a higher proportion of secondary prevention patients (15.7% vs 1.7%; P < 0.001). Compared with suboptimal patients, the optimal patients had lower adjusted mortality (0.7% vs 1.9% at 1-year and 2.9% vs 5.1% at 3-year post-index event; both P < 0.001), and higher adjusted health care costs (CA$3758 and CA$6844 at 1-year and 3-year post-index event, respectively; both P < 0.001). Among the secondary prevention group, the optimal patients had lower adjusted mortality (2.4% and 5% absolute reduction at 1-year and 3-year post-index event, respectively; both P < 0.001) at no additional costs. The results were robust across 5 definitions of optimal dyslipidemia control. CONCLUSIONS: Patients with optimal dyslipidemia control have lower mortality and incur modestly higher costs. However, secondary prevention patients experience lower mortality at no additional costs.

RESUMO

PURPOSE: Familial hypercholesterolemia (FH) is a genetic disease characterized by increased levels of low-density lipoprotein cholesterol (LDL-C). It is underdiagnosed and undertreated despite relatively high prevalance and significant association with increased mortality. We aimed to determine treatment status and compliance in patients with LDL-C ≥ 250 mg/dL and FH. DESIGN: Patients older than 18 years old and have a serum LDL-C ≥ 250 mg/dL between January 2010 to December 2016 were identified from the hospital database. A phone survey was performed. Demographic features, smoking status, alcohol use, exercise, cardiovascular disease (CVD), use of medication for dyslipidemia, and CVD and high cholesterol levels in the family were questioned. Dutch Lipid Clinical Network Criteria was used to classify patients. The study was registered to Clinicaltrials.gov in July 2020 (NCT04494464). RESULTS: 1365 patients with a LDL-C ≥ 250 mg/dL were identified. Patients that could not be reached and who refused to interview were excluded and the data of 367 patients were analyzed. There were 248 (67.6%) female and 119 (32.4%) male patients and mean age was 50.52 ± 11.66. LDL-C was ≥330 mg/dL in 50 (13.6%) and 250-329 mg/dL in 317 (86.4%) patients. Forty (10.9%) patients were classified as definite, 181 (49.3%) as probable and 146 (39.8%) as possible FH. 213 (58.0%) patients were not receiving lipid-lowering treatment, and 162 (76.1%) stated that medication was never recommended previously, 30 (14.1%) had stopped medication him/herself and 21 (9.8%) had stopped medication with the advice of the physician. Among patients with definite/probable FH, 84 (38.0%) had CVD and the rate of lipid-lowering drug use in these patients was 58.3%. CONCLUSION: A significant proportion of patients with LDL-C ≥ 250 mg/dL were not taking lipid-lowering drugs. Similar with many other studies, diagnosis, and treatment rates of FH patients were very low in our study. Further national studies are required to increase awareness of the disease in both physicians and patients.

RESUMO

This study investigated the safety and therapeutic effect of a multiherbal tea (MHT) on Triton X-1339-induced hyperlipidemia and associated biochemical and tissue dysfunctions. An infusion of the MHT was assessed for phytoconstituents, proximate and mineral composition, and antioxidant activity. Wistar rats administered 200 mg/kg Triton X-1399 were post-treated with MHT for 14 days followed by biochemical estimations in serum, heart, liver, and kidney of animals. Hematological and histopathological evaluations of the blood, and liver, respectively, were also performed. Different phytochemicals were detected in MHT, toxic metals were absent and antioxidant activity was appreciable. Disturbances in glucose level and redox homeostasis, alterations in liver, kidney, and heart function markers, and imbalances in hematological parameters precipitated by triton toxicity were mitigated by posttreatment with MHT. Multiherbal tea also ameliorated triton-induced hepatic histoarchitectural abnormalities. These results suggest that MHT is apparently an effective antilipemic tea with minimal or no side effects. PRACTICAL APPLICATIONS: Hyperlipidemia is one of the core risk factors for arteriosclerosis and a major contributor to other adverse health conditions. The prevalence of hyperlipidemia has increased drastically in the last few decades. Plant and plant products have been extensively used in the management of dyslipidemia and many plant-based antilipemic products with poorly defined toxicity and pharmacological profiles abound in the market. The results of this study demonstrated the protective effects of a MHT against triton-induced hyperlipidemia, atherogenic tendency, and dysfunction of key organs in rats and lent credence to its therapeutic relevance in the management of hyperlipidemia and related diseases.

RESUMO

Despite many improvements in its prevention and management, acute coronary syndrome (ACS) remains a major cause of morbidity and mortality in the developed world. Lipid management is an important part of secondary prevention after ACS, but many patients currently remain undertreated and do not attain guideline-recommended levels of low-density lipoprotein cholesterol reduction. This review details the current state of evidence on lipid management in patients presenting with ACS, provides directions for identification of patients who may benefit from early escalation of lipid-lowering therapy, and discusses novel lipid-lowering medication that is currently under investigation in clinical trials. Moreover, a treatment algorithm aimed at attaining guideline-recommended low-density lipoprotein cholesterol levels is proposed. Despite important advances in the initial treatment and secondary prevention of ACS, ≈20% of ACS survivors experience a subsequent ischemic cardiovascular event within 24 months, and 5-year mortality ranges from 19% to 22%. Knowledge of the current state of evidence-based lipid management after ACS is of paramount importance to improve outcomes after ACS.

RESUMO

BACKGROUND: Bempedoic acid is a novel adenosine triphosphate citrate lyase inhibitor shown to reduce low density lipoprotein cholesterol when used as an adjunct lipid-lowering therapy in patients with high cardiovascular disease (CVD) risk. OBJECTIVE: Our analysis aimed to determine the price at which bempedoic acid would be cost-effective from the Australian health care perspective. METHODS: A Markov model was designed using data from the Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen (CLEAR) Harmony trial, to model the clinical outcomes and costs of 1000 patients treated with bempedoic acid over a lifetime horizon. Relevant health states were "Alive with CVD," "Alive with recurrent CVD," and "Dead." With annual cycles, patients were at risk of a nonfatal myocardial infarction, coronary revascularization, and death from CVD or non-CVD causes. Costs and utilities were obtained from published sources. Outcomes of interest were the incremental cost-effectiveness ratios in terms of cost per quality-adjusted life year (QALY) gained and cost per year of life saved. Outcomes were discounted at 5% per annum. RESULTS: Among 1000 individuals, bempedoic acid in addition to statin therapy was estimated to save 122 (discounted) years of life and 103 (discounted) QALYs compared with statin therapy alone. At an acquisition cost of AU$584.40 per year (USD$397.01), bempedoic acid would be considered cost-effective within the Australian setting, with an incremental cost-effectiveness ratio of AU$49,890 per QALY gained (USD$33,893) and AU$42,433 per year of life saved (USD$28,827). CONCLUSIONS: Bempedoic acid may be cost-effective within the Australian health care setting at an annual acquisition price less than $600.

RESUMO

INTRODUCTION: The Mississippi Delta has high rates of chronic disease and is known for its poor health outcomes and health disparities. The University of Mississippi School of Pharmacy (UMSOP) and the Mississippi State Department of Health partnered in 2009 through the Mississippi Delta Health Collaborative to reduce health disparities and improve clinical outcomes by expanding the UMSOP's evidence-based medication therapy management (MTM) initiative, focused in Mississippi's 18-county Delta region, to federally qualified health centers (FQHCs) in 4 of those counties. METHODS: Between January 2009 and August 2018, the MTM initiative targeted FQHC patients aged 18 years or older with a diagnosis of diabetes, hypertension, and/or dyslipidemia. Pharmacists initially met face-to-face with patients to review all medications, provide education about chronic diseases, identify and resolve drug therapy problems, and take appropriate actions to help improve the effectiveness of medication therapies. Clinical parameters evaluated were systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and hemoglobin A1c (HbA1c). RESULTS: The analysis included 335 patients with hypertension (n = 287), dyslipidemia (n = 131), and/or diabetes (n = 331). Significant mean reductions occurred in the following metrics: SBP (7.1 mm Hg), DBP (6.3 mm Hg), LDL cholesterol (24.9 mg/dL), triglycerides (45.5 mg/dL), total cholesterol (37.7 mg/dL), and HbA1c (1.6% [baseline ≥6%] and 1.9% [baseline ≥9%]). CONCLUSION: Despite the cultural and environmental disadvantages present in the Mississippi Delta, the integrated MTM treatment program demonstrated significant health improvements across 3 chronic diseases: hypertension, dyslipidemia, and diabetes. This model demonstrates that a partnership between public health and pharmacy is a successful and innovative approach to care.
