INTRODUCTION: Adherence to medications for cardiovascular disease and its risk factors is less than optimal, although greater adherence to medication has been shown to reduce the risk factors for cardiovascular disease. This paper examines the economics of tailored pharmacy interventions to improve medication adherence for cardiovascular disease prevention and management. METHODS: Literature from inception of databases to May 2019 was searched, yielding 29 studies for cardiovascular disease prevention and 9 studies for cardiovascular disease management. Analyses were done from June 2019 through May 2020. All monetary values are in 2019 U.S. dollars. RESULTS: The median intervention cost per patient per year was $246 for cardiovascular disease prevention and $292 for cardiovascular disease management. The median change in healthcare cost per person per year due to the intervention was -$355 for cardiovascular disease prevention and -$2,430 for cardiovascular disease management. The median total cost per person per year was -$89 for cardiovascular disease prevention, with a median return on investment of 0.01. The median total cost per person per year for cardiovascular disease management was -$1,080, with a median return on investment of 7.52, and 6 of 7 estimates indicating reduced healthcare cost averted exceeded intervention cost. For cardiovascular disease prevention, the median cost per quality-adjusted life year gained was $11,298. There were no cost effectiveness studies for cardiovascular disease management. DISCUSSION: The evidence shows that tailored pharmacy-based interventions to improve medication adherence are cost effective for cardiovascular disease prevention. For cardiovascular disease management, healthcare cost averted exceeds the cost of implementation for a favorable return on investment from a healthcare systems perspective.

INTRODUCTION: An estimated 116 million American adults (47.3%) have hypertension. Most adults with hypertension do not have it controlled-3 in 4 (92.1 million) U.S. adults with hypertension have a blood pressure ≥130/80 mmHg. The Pharmacists' Patient Care Process is a standardized patient-centered approach to the provision of pharmacist care that is done in collaboration with other healthcare providers. Through the Michigan Medicine Hypertension Pharmacists' Program, pharmacists use the Pharmacists' Patient Care Process to provide hypertension management services in collaboration with physicians in primary care and community pharmacy settings. In 2019, the impact of Michigan Medicine Hypertension Pharmacists' Program patient participation on blood pressure control was evaluated. METHODS: Propensity scoring was used to match patients in the intervention group with patients in the comparison group and regression analyses were then conducted to compare the 2 groups on key patient outcomes. Negative binomial regression was used to examine the number of days with blood pressure under control. The findings presented in this brief are part of a larger multimethod evaluation. RESULTS: More patients in the intervention group than in the comparison group achieved blood pressure control at 3 months (66.3% vs 42.4%) and 6 months (69.1% vs 56.5%). The intervention group experienced more days with blood pressure under control within a 3-month (18.6 vs 9.5 days) and 6-month period (57.0 vs 37.4 days) than the comparison group did. CONCLUSIONS: Findings support the effectiveness of the Michigan Medicine Hypertension Pharmacists' Program approach to implementing the Pharmacists' Patient Care Process to improve blood pressure control.

BACKGROUND: The literature lacks information about the use and cost of prescribed antihypertensive medications, especially by the type and class of medication prescribed. OBJECTIVE: This study investigated the uses and expenses of antihypertensive medications among hypertensive adults in the United States. METHODS: Using the 2014-2015 Medical Expenditure Panel Survey data, adult men and nonpregnant women aged 18 or older who had a diagnosis code of hypertension and used any prescribed antihypertensive medication were included in the study (n=10,971). Adults with hypertension who were using a single antihypertensive medication were defined as single medication users, and those using two or more medications were defined as multiple medication users. Medications were classified into angiotensin-converting-enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), thiazide-type diuretics (TDs), beta-blockers (BBs), and others. The average annual total antihypertensive medication expenses and the expenditures of each medication class were estimated by using generalized linear models with a log link and gamma distribution and were adjusted to 2015 US dollars. RESULTS: Among 10,971 hypertensive adults, 4759 (44.1%) were single medication users, and 6212 (55.9%) were multiple medication users. The average annual total cost for antihypertensive medications was $336 per person (95% confidence interval [CI]=$319-$353); $199 (95% CI=$177-$221) for single medication users and $436 (95% CI=$413-$459) for multiple medication users. The average annual costs for each medication class were estimated at $438 (95% CI=$384-$492) for ARBs and $49 for TDs (95% CI=$44-$55). CONCLUSIONS: Users of multiple medications incurred more than twice the expense than single medication users. When comparing classes of medications, the cost for ARBs was the highest, whereas the cost for TDs was the lowest. This information can be used in evaluating the cost-effectiveness of antihypertension therapies.

Patients' adherence to antihypertensive medications is key to controlling high blood pressure. Evidence-based strategies to improve adherence exist, but their use, individually and in combination, has not been described. 2015-2016 DocStyles data were analyzed to describe health care professionals' and their practices' use of 10 strategies to improve antihypertensive medication adherence across 3 categories: prescribing, education, and tracking/encouragement. Among 1590 respondents, a mean of using 5 strategies was reported, with individual strategy use ranging from 17.2% (providing patients adherence-related rewards) to 69.4% (prescribing once-daily regimens). Those with higher odds of using >/=7 strategies and strategies across all 3 categories included: (1) nurse practitioners compared to family practitioners/internists and (2) health care professionals in practices with standardized hypertension treatment protocols who routinely recommend home blood pressure monitor use compared to respondents without those characteristics. Despite using an array of evidence-based adherence-promoting strategies, additional opportunities exist for health care professionals to provide adherence support among hypertensive patients.

CONTEXT: Hypertension affects one third of the U.S. adult population. Although cost-effectiveness analyses of antihypertensive medicines have been published, a comprehensive systematic review across medicine classes is not available. EVIDENCE ACQUISITION: PubMed, Embase, Cochrane Library, and Health Technology Assessment were searched to identify original cost-effectiveness analyses published from 1990 through August 2016. Results were summarized by medicine class: angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), thiazide-type diuretics, beta-blockers, and others. Incremental cost-effectiveness ratios (ICERs) were adjusted to 2015 U.S. dollars. EVIDENCE SYNTHESIS: Among 76 studies reviewed, 14 compared medicines with no treatment, 16 compared medicines with conventional therapy, 29 compared between medicine classes, 13 compared within medicine class, and 11 compared combination therapies. All antihypertensives were cost effective compared with no treatment (ICER/quality-adjusted life year [QALY]=dominant-$19,945). ARBs were more cost effective than CCBs (ICER/QALY=dominant-$13,016) in nine comparisons, whereas CCBs were more cost effective than ARBs (ICER/QALY=dominant) in two comparisons. ARBs were more cost effective than ACEIs (ICER/QALY=dominant-$34,244) and beta-blockers (ICER/QALY=$1,498-$18,137) in all eight comparisons. CONCLUSIONS: All antihypertensives were cost effective compared with no treatment. ARBs appeared to be more cost effective than CCBs, ACEIs, and beta-blockers. However, these latter findings should be interpreted with caution because these findings are not robust due to the substantial variability across the studies, including study settings and analytic models, changes in the cost of generic medicines, and publication bias.

Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease (CVD) risk among persons with impaired glucose tolerance (IGT), but it is unclear whether they should be implemented among persons without IGT. We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes. We systematically searched MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane Library, and PsychInfo databases, from inception to May 4, 2016. We selected randomized controlled trials of lifestyle interventions, involving physical activity (PA), dietary (D), or combined strategies (PA+D) with follow-up duration ≥12 months. We excluded all studies that included individuals with IGT, confirmed by 2-hours oral glucose tolerance test (75g), but included all other studies recruiting populations with different glycemic levels. We stratified studies by baseline glycemic levels: (1) low-range group with mean fasting plasma glucose (FPG) <5.5mmol/L or glycated hemoglobin (A1C) <5.5%, and (2) high-range group with FPG ≥5.5mmol/L or A1C ≥5.5%, and synthesized data using random-effects models. Primary outcomes in this review included systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglycerides (TG). Totally 79 studies met inclusion criteria. Compared to usual care (UC), lifestyle interventions achieved significant improvements in SBP (-2.16mmHg[95%CI, -2.93, -1.39]), DBP (-1.83mmHg[-2.34, -1.31]), TC (-0.10mmol/L[-0.15, -0.05]), LDL-C (-0.09mmol/L[-0.13, -0.04]), HDL-C (0.03mmol/L[0.01, 0.04]), and TG (-0.08mmol/L[-0.14, -0.03]). Similar effects were observed among both low-and high-range study groups except for TC and TG. Similar effects also appeared in SBP and DBP categories regardless of follow-up duration. PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions. In adults without IGT or diabetes, lifestyle interventions resulted in significant improvements in SBP, DBP, TC, LDL-C, HDL-C, and TG, and might further reduce CVD risk.
