Transatlantic lipid guideline divergence: same data but different interpretations

Despite consensus that excessive circulating concentrations of apoB-lipoproteins is a key driver for the atherosclerotic process and that treatments that low-density lipoprotein cholesterol lowering by up-regulation of low-density lipoprotein cholesterol receptor expression reduces that risk, divergent viewpoints on interpretation of study data have resulted in substantial differences in European and American lipid guideline recommendations. This article explores those differences and highlights the importance of understanding guideline-based lipid management to improve patient care and reduce the risk of clinical atherosclerotic cardiovascular disease

Neighborhood socioeconomic status, Medicaid coverage and medical management of myocardial infarction: Atherosclerosis risk in communities (ARIC) community surveillance

<p>Abstract</p> <p>Background</p> <p>Pharmacologic treatments are efficacious in reducing post-myocardial infarction (MI) morbidity and mortality. The potential influence of socioeconomic factors on the receipt of pharmacologic therapy has not been systematically examined, even though healthcare utilization likely influences morbidity and mortality post-MI. This study aims to investigate the association between socioeconomic factors and receipt of evidence-based treatments post-MI in a community surveillance setting.</p> <p>Methods</p> <p>We evaluated the association of census tract-level neighborhood household income (nINC) and Medicaid coverage with pharmacologic treatments (aspirin, beta [β]-blockers and angiotensin converting enzyme [ACE] inhibitors; optimal therapy, defined as receipt of two or more treatments) received during hospitalization or at discharge among 9,608 MI events in the ARIC community surveillance study (1993-2002). Prevalence ratios (PR, 95% CI), adjusted for the clustering of hospitalized MI events within census tracts and within patients, were estimated using Poisson regression.</p> <p>Results</p> <p>Seventy-eight percent of patients received optimal therapy. Low nINC was associated with a lower likelihood of receiving β-blockers (0.93, 0.87-0.98) and a higher likelihood of receiving ACE inhibitors (1.13, 1.04-1.22), compared to high nINC. Patients with Medicaid coverage were less likely to receive aspirin (0.92, 0.87-0.98), compared to patients without Medicaid coverage. These findings were independent of other key covariates.</p> <p>Conclusions</p> <p>nINC and Medicaid coverage may be two of several socioeconomic factors influencing the complexities of medical care practice patterns.</p

Patient considerations in the management of gout and role of combination treatment with lesinurad

Liza W Claus, Joseph J Saseen Department of Clinical Pharmacy, Skaggs School of Pharmacy and Pharmaceutical Sciences, University of Colorado, Aurora, CO, USA Abstract: Gouty arthritis is one of the most common rheumatic diseases, and the prevalence continues to rise, which is likely related to increased incidence of comorbidities, lifestyle factors, and suboptimal utilization of urate-lowering therapy. In recent years, multiple new guidelines have been published along with the approval of novel drug therapies. Still, gout remains a poorly controlled disease state that is accompanied by a reduced health-related quality of life, increased health care utilization, and overall negative socioeconomic effects, all of which have a negative impact on patient-related health outcomes. The key to success in gout management is utilization of urate-lowering therapy to prevent recurrence of acute gouty arthritis and to resolve tophi, if present. Xanthine oxidase inhibitors are first-line medications for the prevention of recurrent gout followed by uricosurics, including lesinurad (a uric acid reabsorption inhibitor) as an add-on option. The recent US Food and Drug Administration Safety Communication related to cardiovascular risk with febuxostat may result in increased use of allopurinol in combination therapy with a uricosuric agent such as lesinurad. In this review, we discuss gout management, clinical end points, and patient-related outcomes for consideration, summarize the evidence for combination therapy to achieve serum urate targets, and focus on lesinurad as a novel newer medication for the prevention of gout.

Evaluation of fracture risk and potential drug holidays for postmenopausal women on long-term bisphosphonate therapy

Matthew D Kostoff, Joseph J Saseen, Laura M BorgeltDepartments of Clinical Pharmacy and Family Medicine, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences and School of Medicine, Aurora, CO, USAStudy objective: To describe characteristics of postmenopausal women on long-term bisphosphonate therapy who fall into one of four fracture risk categories (low, mild, moderate, high), and to determine the prevalence of women eligible for a drug holiday.Design: Retrospective electronic health record review.Setting: Eight primary care clinics within a university-based health care system.Patients: A total of 201 postmenopausal women of ages 55&ndash;89 years, with osteopenia or osteoporosis, prescribed bisphosphonate therapy for &gt;4 years, between October 10, 2002 and September 9, 2012.Main results: The patients&#39; mean age was 71.4 (&plusmn;8.2) years; their mean body mass index was 25.3 (&plusmn;5.6) kg/m2; and 73.1% were white. Seventy-four out of 201 patients (36.8%) were low-risk; 10/201 (5.0%) were mild-risk; 72/201 (35.8%) were moderate-risk; and 45/201 (22.4%) were high-risk. Eighty-one women (40.3%) were eligible for a drug holiday or discontinuation. The estimated drug cost avoided per eligible patient was $574.80. Calcium and/or vitamin D supplementation was documented in 52.7% of women.Conclusion: More than one-third of postmenopausal women taking long-term bisphosphonate therapy had low fracture risk, and over 40% of our patients were eligble for a drug holiday or discontinuation. These data emphasize the need to accurately assess risk and benefit in patients treated with bisphosphonate therapy.Keywords: postmenopausal osteoporosis, bisphosphonates, drug holiday, fractur

Incremental increases in economic burden parallels cardiometabolic risk factors in the US

R Brett McQueen,1 Vahram Ghushchyan,1,2 Temitope Olufade,3 John J Sheehan,4 Kavita V Nair,1 Joseph J Saseen1,5 1Department of Clinical Pharmacy, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, Anschutz Medical Campus, Aurora, CO, USA; 2College of Business and Economics, American University of Armenia, Yerevan, Armenia; 3AstraZeneca, Wilmington, DE, 4AstraZeneca, Fort Washington, PA, 5Department of Family Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO, USA Objective: Estimate the economic burden associated with incremental increases in the number of cardiometabolic risk factors (CMRFs) in the US. Methods: We used the nationally representative Medical Expenditure Panel Survey from 2010 to 2012 to create a retrospective cohort of people based on the number of CMRFs (one, two, and three or four), and a comparison cohort of people with zero CMRFs. CMRFs included abdominal obesity, elevated blood pressure, elevated triglycerides, and elevated glucose and&nbsp;were defined using diagnostic codes, prescribed medications, and survey responses. Adjusted regression analysis was developed to compare health expenditures, utilization, and lost-productivity differences between the cohorts. Generalized linear regression was used for health care expenditures, and negative binomial regression was used for utilization and productivity, controlling for individual characteristics. Results: The number of CMRFs was associated with significantly more annual utilization, health care expenditures, and reduced productivity. As compared with people with zero CMRFs, people with one, two, and three or four CMRFs had 1.15 (95% confidence interval [CI]: 1.06, 1.24), 1.37 (95% CI: 1.25, 1.51), and 1.39 (95% CI: 1.22, 1.57) times higher expected rate of emergency room visits, respectively. Compared with people with zero CMRFs, people with one, two, and three or four CMRFs had increased incremental health care expenditures of US$417 (95$70, $763), US$2,326 (95% CI: $1,864,$2,788), and US$4,117 (95$3,428, $4,807), respectively. Those with three or four CMRFs reported employment of 60%, compared with 80% in patients with zero CMRFs. People with three or four CMFRs had 1.75 (95% CI: 1.42, 2.17) times higher expected rate of days missed at work due to illness, compared with people with zero CMRFs. Conclusion: Our findings demonstrate a direct association between economic burden and number of CMRFs. Although this was expected, the increase in burden that was independent from the cost of cardiovascular disease was surprising.

Understanding barriers to medication adherence in the hypertensive population by evaluating responses to a telephone survey

Background: Although hypertension is a major risk factor for cardiovascular disease, adherence to hypertensive medications is low. Previous research identifying factors influencing adherence has focused primarily on broad, population-based approaches. Identifying specific barriers for an individual is more useful in designing meaningful targeted interventions. Using customized telephonic outreach, we examined specific patient-reported barriers influencing hypertensive patients' nonadherence to medication in order to identify targeted interventions. Methods: A telephone survey of 8692 nonadherent hypertensive patients was conducted. The patient sample comprised health plan members with at least two prescriptions for antihypertensive medications in 2008. The telephone script was based on the "target" drug associated with greatest nonadherence (medication possession ratio [MPR] <80%) during the four-month period preceding the survey. Results: The response rate was 28.2% of the total sample, representing 63.8% of commercial members and 37.2% of Medicare members. Mean age was 63.4 years. Mean MPR was 61.0% for the target drug. Only 58.2% of Medicare respondents and 60.4% of commercial respondents reported "missing a dose of medication". The primary reason given was "forgetfulness" (61.8% Medicare, 60.8% commercial), followed by "being too busy" (2.7% Medicare, 18.5% commercial) and "other reasons" (21.9% Medicare, 8.1% commercial) including travel, hospitalization/sickness, disruption of daily events, and inability to get to the pharmacy. Prescription copay was a barrier for less than 5% of surveyed patients. Conclusion: Our findings indicate that events interfering with daily routine had a significant impact on adherence. Medication adherence appears to be a patterned behavior established through the creation of a routine and a reminder system for taking the medication. Providers should assess patients' daily schedules and medication-taking competency to develop and promote a medication routine. © 2011 2011 Nair et al, publisher and licensee Dove Medical Press Ltd

An evaluation of the impact of patient cost sharing for antihypertensive medications on adherence, medication and health care utilization, and expenditures

Jacqueline A Pesa1, Jill Van Den Bos2, Travis Gray2, Colleen Hartsig2, Robert Brett McQueen3, Joseph J Saseen3, Kavita V Nair31Janssen Scientific Affairs, LLC, Louisville, CO, USA; 2Milliman, Inc, Denver, CO, USA; 3University of Colorado Anschutz Medical Campus, Aurora, CO, USAObjective: To assess the impact of patient cost-sharing for antihypertensive medications on the proportion of days covered (PDC) by antihypertensive medications, medical utilization, and health care expenditures among commercially insured individuals assigned to different risk categories.Methods: Participants were identified from the Consolidated Health Cost Guidelines (CHCG) database (January 1, 2006&amp;ndash;December 31, 2008) based on a diagnosis (index) claim for hypertension, continuous enrollment &amp;ge;12 months pre- and post-index, and no prior claims for antihypertensive medications. Participants were assigned to: low-risk group (no comorbidities), high-risk group (1+ selected comorbidities), or very high-risk group (prior hospitalization for 1+ selected comorbidities). The relationship between patient cost sharing and PDC by antihypertensive medications was assessed using standard linear regression models, controlling for risk group membership, and various demographic and clinical factors. The relationship between PDC and health care service utilization was subsequently examined using negative binomial regression models.Results: Of the 28,688 study patients, 66% were low risk. The multivariate regression model supported a relationship between patient cost sharing per 30-day fill and PDC in the following year. For every US$1.00 increase in cost sharing, PDC decreased by 1.1 days (P &amp;lt; 0.0001). Significant predictors of PDC included high risk, older age, gender, Charlson Comorbidity Index score, geography, and total post-index insurer- and patient-paid costs. An increase in PDC was associated with a decrease in all-cause and hypertension-related inpatient, outpatient, and emergency room visits and medical, pharmacy, and total costs.Conclusions: The trend has been for managed care organizations and employers to require patients to bear a greater out-of-pocket burden for health care resources consumed. This study illustrates the potential adverse effects of higher patient cost sharing among patients with hypertension stratified by different risk levels. A decrease in PDC was predictive of higher resource utilization and health care costs, which should be of interest to payers and employers alike.Keywords: hypertension, adherence, cost sharing, outcome
