Primary Care and Infectious Disease Provider Adherence to HIV Pre-exposure Prophylaxis (PrEP) Prescribing and Monitoring Recommendations.

This study aimed to compare primary care (PC) and infectious diseases (ID) provider adherence to HIV pre-exposure prophylaxis (PrEP) prescribing and monitoring parameters outlined in Centers for Disease Control/Department of Health and Human Services (CDC/DHHS) guidelines. This retrospective cohort analysis from 2017 to 2022 used prescription and laboratory order data to identify patients prescribed PrEP by PC or ID providers. Primary endpoints assessed were adherence to baseline and follow-up HIV monitoring recommendations in the 12 months following the initial PrEP prescription. Secondary endpoints included appropriate PrEP prescription order quantities (≤ 90-day supply), appropriate renal function monitoring, and identification of factors independently associated with follow-up HIV monitoring adherence. Of the 324 eligible patients identified, 112 received PrEP from an ID specialist and 212 from a PC provider. Patients prescribed PrEP from an ID specialist were more likely to have appropriately completed baseline HIV monitoring (OR = 2.56, 95% CI 1.20, 5.47), follow-up HIV monitoring (OR = 1.81, 95% CI 1.08, 3.05), and renal function monitoring (OR = 2.81, 95% CI 1.69, 4.68); The ID group was also more likely to have PrEP prescriptions appropriately authorized for a days' supply of ≤ 90 days (OR = 4.41, 95% CI 2.60, 7.48). Patients receiving PrEP care from ID specialists had better adherence to all assessed PrEP prescribing and monitoring recommendations compared to those receiving care from PC providers.

Factors associated with antihypertensive monotherapy among US adults with treated hypertension and uncontrolled blood pressure overall and by race/ethnicity, National Health and Nutrition Examination Survey 2013-2018.

BACKGROUND: Treating hypertension with antihypertensive medications combinations, rather than one medication (ie, monotherapy), is underused in the United States, particularly in certain race/ethnic groups. Identifying factors associated with monotherapy use despite uncontrolled blood pressure (BP) overall and within race/ethnic groups may elucidate intervention targets in under-treated populations. METHODS: Cross-sectional analysis of National Health and Nutrition Examination Surveys (NHANES; 2013-2014 through 2017-2018). We included participants age ≥20 years with hypertension, taking at least one antihypertensive medication, and uncontrolled BP (systolic BP [SBP] ≥ 140 mmHg or diastolic BP [DBP] ≥ 90 mmHg). Demographic, clinical, and healthcare-access factors associated with antihypertensive monotherapy were determined using multivariable-adjusted Poisson regression. RESULTS: Among 1,597 participants with hypertension and uncontrolled BP, age- and sex- adjusted prevalence of monotherapy was 42.6% overall, 45.4% among non-Hispanic White, 31.9% among non-Hispanic Black, 39.6% among Hispanic, and 50.9% among non-Hispanic Asian adults. Overall, higher SBP was associated with higher monotherapy use, while older age, having a healthcare visit in the previous year, higher body mass index, and having heart failure were associated with lower monotherapy use. CONCLUSION: Clinical and healthcare-access factors, including a healthcare visit within the previous year and co-morbid conditions were associated with a higher likelihood of combination antihypertensive therapy.

Evaluation of the Clinical Impact of Thromboprophylaxis in Patients With COVID-19 Following Hospital Discharge.

BACKGROUND: Data are limited regarding the incidence of thromboembolism post-hospital discharge among COVID-19 patients. Guidelines addressing the role of extended thromboprophylaxis for COVID-19 patients are limited and conflicting. OBJECTIVE: The purpose of this study was to evaluate the incidence of post-discharge thromboembolic and bleeding events and the role of thromboprophylaxis among COVID-19 patients. METHODS: A retrospective analysis was conducted of hospitalized patients with symptomatic COVID-19 infection who were discharged from a University of Colorado Health (UCHealth) hospital between March 1, 2020, and October 31, 2020. The primary outcome was objectively confirmed thromboembolism within 35 days post-discharge. The main secondary outcome was the incidence of bleeding events within 35 days post-discharge. Outcomes were compared between those who received extended prophylaxis and those who did not. RESULTS: A total of 1171 patients met the study criteria. A total of 13 (1.1%) of patients had a documented thromboembolic event and 10 (0.9%) patients had a documented bleeding event within 35 days post-discharge. None of the 132 patients who received extended prophylaxis had a thromboembolic event compared to 13 of 1039 who did not receive extended prophylaxis (0 and 1.3%, respectively; P = .383). The incidence of bleeding was higher among patients who received extended prophylaxis compared to those who did not (3.0% vs 0.6%, P = .019). CONCLUSIONS AND RELEVANCE: These results suggest that post-discharge extended prophylaxis may be beneficial for select COVID-19 patients, while carefully weighing the risk of bleeding. Application of our findings may assist institutions in development of thromboprophylaxis protocols for discharged COVID-19 patients.

Direct oral anticoagulants versus warfarin in patients with single or double antibody-positive antiphospholipid syndrome.

Warfarin is recognized as the standard treatment for thrombotic antiphospholipid syndrome (APS); however, direct oral anticoagulants (DOACs) represent appealing therapeutic alternatives given their lack of monitoring and limited drug interactions. A few randomized controlled trials comparing rivaroxaban with warfarin showed an increased risk of recurrent thromboembolism, specifically arterial thrombosis, in patients with high risk forms of APS such as those that are triple antibody positive. We conducted a single-center, retrospective cohort study of all patients within our health system from 2015 to 2020 with a diagnosis of APS (single or double antibody positive) and history of venous thromboembolism. We sought to compare the proportion of patients with a recurrent thrombosis when prescribed a DOAC versus warfarin. Among 96 patients included, 57 were prescribed warfarin and 39 were prescribed a DOAC (90% rivaroxaban). The proportion of patients with a recurrent thromboembolism was almost three times higher in the DOAC group (15.4%) compared to the warfarin group (5.3%), although this was not statistically significant (p = 0.15). Major bleeding was not different between groups. Our findings suggest that rivaroxaban may pose an increased risk for recurrent thromboembolism in low risk APS patients that are single or double-antibody positive compared to warfarin. Results of our study should be cautiously applied to DOACs besides rivaroxaban given their small representation in this study.

Prescribing practices of migraine-specific pharmacotherapy associated with emergency department use for migraine.

OBJECTIVE: This study compared migraine medication prescribing between patients with a migraine diagnosis who used versus did not use the emergency department (ED) for migraine. BACKGROUND: Headache is the fifth most common chief complaint for ED visits nationwide and the third most common potentially avoidable ED diagnosis in the University of Colorado Health system. The reasons some patients use the ED for migraine management while others do not and whether some ED admissions might be preventable remain unclear. METHODS: This retrospective cohort study identified adults with migraine-related diagnoses within 1 year before the index date of July 1, 2018 and compared patient characteristics and migraine medication prescribing patterns between those who did or did not have a subsequent migraine-related ED encounter the following year. ED admission notes were manually reviewed to identify potentially preventable circumstances that led to the ED visit. The primary outcome was the proportion of patients with an active triptan prescription at the index date. RESULTS: Of the 3843 patients identified, 35 patients (0.9%) had a migraine-related ED encounter. Of these, 17/35 (49%) had an active triptan prescription compared to 1360/3808 (36%) of non-ED utilizers (p = 0.114), OR 1.22 (95% CI 0.61-2.45). More ED utilizers had an active prescription for opioids (11/35 [31%] vs. 663/3808 [17%], p = 0.030) and migraine preventive therapy (19/35 [54%] vs. 1149/3808 [30%], p = 0.002), and neurology referrals (20/35 [57%] vs. 654/3808 [17%], p < 0.001) compared to non-ED utilizers. The most common circumstance for migraine-related ED visits was nonresponse to migraine abortive medications administered at home. CONCLUSIONS: Triptan prescribing did not differ between ED utilizers and non-ED utilizers for migraine. Overall, less than half of the total patient population had a triptan prescribed. More ED utilizers had neurology referrals, prescriptions for opioids and preventive therapies, and a history of previous ED visit for any reason, which may be markers for higher disease severity or behavior patterns. Future research and interventions to reduce migraine-related ED use could target high-risk patients such as those with previous ED visits for any indication and neurology referrals.

Role of Bempedoic Acid in Clinical Practice.

Many patients do not achieve optimal low-density lipoprotein cholesterol (LDL-C) levels with statins alone; others are unable to tolerate statin therapy. Additional non-statin treatment options including ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, and bile acid sequestrants are often necessary to further reduce the risk of atherosclerotic cardiovascular disease. This review provides practical guidance as to the use of bempedoic acid to lower LDL-C and includes direction as to which patients may benefit and advice for safety monitoring during treatment. Bempedoic acid, a new class of agent, is a prodrug converted to bempedoyl-CoA by very long-chain acyl-CoA synthetase 1, an enzyme with high expression in the liver but that is undetectable in the skeletal muscle. Bempedoic acid inhibits the enzyme adenosine triphosphate (ATP)-citrate lyase, which lies two steps upstream from ß-hydroxy ß-methylglutaryl-CoA reductase in the cholesterol biosynthesis pathway. In clinical trials conducted in patients with or at risk for atherosclerotic cardiovascular disease or familial heterozygous hypercholesterolemia, bempedoic acid in combination with statins and/or ezetimibe significantly reduced LDL-C, apolipoprotein B, and high-sensitivity C-reactive protein compared with placebo. Bempedoic acid is generally well tolerated with no clinically meaningful increase in muscle-related symptoms relative to placebo, even in patients taking maximally tolerated statins. A small increase in serum uric acid (mean increase 0.8 mg/dL) is the most noteworthy adverse effect. Bempedoic acid provides an effective and generally well-tolerated medication to further reduce LDL-C in patients taking maximally tolerated statins or manage LDL-C levels in those who are unable to take statins. The potential for a reduced incidence of major cardiovascular events with bempedoic acid is being investigated in the CLEAR Outcomes trial, with results expected in 2023.

Pharmacist-administered long-acting injectable PCSK9 service: A solution to improve patient access and adherence.

In 2015, 2 proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, alirocumab and evolocumab, were approved by Food and Drug Administration (FDA). Both therapies reduce low-density lipoprotein cholesterol (LDL-C) by approximately 60% and reduce atherosclerotic cardiovascular disease (ASCVD) risk in patients with established ASCVD when added to background statin therapy. The initial cost of these medications was approximately $15,000 per year, which made them largely cost-prohibitive for many patients and the overall health care system. In recent years, the cost of both agents has been reduced by 60%, and they are no longer only available through specialty pharmacies. In addition, a third PCSK9-modulating therapy, inclisiran, is nearing FDA approval. Ongoing inclisiran therapy only requires biannual subcutaneous administration and achieves LDL-C reductions of approximately 50%. As the use of PCSK9-modulating therapies increases, models that improve adherence and persistence over time will be critical to ensure patient access and maximize their value. Community pharmacists can play an important role helping patients not only obtain access to these therapies by navigating previous authorization requests but also adhere to therapy by offering administration. Community pharmacists can also provide therapeutic monitoring using point-of-care lipid testing to ensure efficacy over time. Such a service could potentially be sustained through reimbursement for administration and point-of-care lipid testing. Given the cost of these therapies, innovative models involving community pharmacists will be necessary to ensure patient access to these preventive therapies and minimize overall costs to the health care system.

Pharmacists' Utilization of Non-HDL-C Levels in Managing Patients With Lipid Disorders.

Background: Since 2013 there have been cholesterol guideline changes impacting pharmacists' clinical practice in managing lipid disorders. For more than a decade, cholesterol management was based on the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol Adult Treatment Panel III guideline, highlighting non-high-density lipoprotein cholesterol (non-HDL-C) as a secondary target in persons with triglycerides ≥200 mg/dL, after low-density lipoprotein cholesterol goal attainment. The 2013 American College of Cardiology and American Heart Association (ACC/AHA) guideline differed from the traditional management of dyslipidemia, in part no longer emphasizing the utilization of non-HDL-C levels. Objective: To measure pharmacists' attitudes and behavior regarding utilization of non-HDL-C level calculation before and after the inception of the 2013 ACC/AHA cholesterol guideline. Methods: Pharmacists in the American College of Clinical Pharmacy ambulatory care listserv participated in an electronic survey in November 2013, before the inception of the 2013 ACC/AHA guideline, and again in October 2018. Results: We collected 391 usable responses from participants; 212 responses in 2013 and 179 responses in 2018. The before and after comparison revealed that respondents in 2013 reported significantly higher frequency of calculating non-HDL-C levels (mean = 1.88, SD = 0.80) than respondents in 2018 (mean = 1.66, SD = 0.79) (P ≤ .001). Also, the frequency that non-HDL-C level calculation alters decisions regarding course of treatment was lower in the 2018 (mean = 3.50, SD = 1.06) in comparison with 2013 (mean = 3.77, SD = 0.88) (P ≤ .05). Furthermore, pharmacists were more favorable toward the inclusion of non-HDL-C level calculation in 2018 (mean = 3.77, SD = 1.05) than in 2013 (mean = 3.13, SD = 1.33) (P ≤ .001). Conclusion and Relevance: Clinical pharmacists' utilization of non-HDL-C levels in the clinical management of patients with hypercholesterolemia has decreased, highlighting the need for further education on the importance of evaluating non-HDL-C levels in the very high-risk atherosclerotic cardiovascular disease population.

Effectiveness of Methenamine for UTI Prevention in Older Adults.

Background: Methenamine is a drug used for the prevention of lower urinary tract infections (UTIs). However, efficacy has not been established in older adults or patients with varying degrees of kidney function. Objective: To evaluate the effectiveness of methenamine for the prevention of UTI in adults 60 years and older. Methods: This was a retrospective, pre-post, observational study. The study included primary care patients 60 years and older who were taking methenamine between January 1, 2015, and September 30, 2018. The primary outcome was the time to first UTI after methenamine initiation compared with the average time between UTIs in the 12 months prior to methenamine initiation. Results: Of 434 patients reviewed, 150 met inclusion criteria. The average time to UTI was 3.3 months prior to methenamine initiation compared with 5.5 months after methenamine initiation (P = 0.0004). There were 33 patients (22%) who did not have a UTI after methenamine initiation. Also, 14 patients (9.3%) had a calculated CrCl <30 mL/min at baseline. The average time to UTI in these patients was 3.3 months prior to methenamine initiation compared with 12.7 months after initiation (P < 0.0001). Conclusion and Relevance: Methenamine use was associated with a longer time to UTI in older adults with varying degrees of kidney function. The effectiveness of methenamine appeared to be similar regardless of kidney function, which is new evidence. Because of a lack of acquired resistance, methenamine may be an effective option for UTI prophylaxis in older adults.

Need for a Judicious Use of Nonsteroidal Anti-inflammatory Drugs to Avoid Community-Acquired Acute Kidney Injury.

Millions of Americans use over-the-counter analgesics on a daily basis, and nearly 100 million nonsteroidal anti-inflammatory drug (NSAID) prescriptions are filled per year. In high-risk patients, these medications can disrupt kidney hemodynamics and precipitate community-acquired acute kidney injury (CA-AKI). The risk of NSAID-associated CA-AKI increases 3- to 5-fold in patients taking renin-angiotensin system inhibitors and diuretics concurrently. CA-AKI increases the risk of developing chronic kidney disease (CKD) or accelerating progression of pre-existing CKD. Importantly, many cases of NSAID-induced CA-AKI may be avoided by identifying high-risk patients and providing patient and provider education on when to avoid these medications and minimize risk.

Social and Psychosocial Determinants of Health Associated With Uncontrolled Diabetes in a Federally Qualified Health Center Population.

PURPOSE: Many people with diabetes have difficulty achieving glycemic targets, and social and psychosocial determinants of health may influence their ability to obtain glycemic goals. The objective of this study was to identify characteristics independently associated with A1C >9% or untested A1C compared to those with A1C ≤9% at a federally qualified health center. METHODS: This retrospective cohort study included people with a diagnosis of diabetes, who were 18-89 years of age and had a medical evaluation from a primary care provider between 1 September 2016 and 31 August 2017. The primary outcome was to identify characteristics associated with an A1C >9% or untested A1C compared to those with an A1C ≤9%. RESULTS: Of 6,185 patients meeting inclusion criteria, 2,965 (48%) had uncontrolled A1C. In the uncontrolled A1C group, 1,549 patients (52%) were female, 1,296 (44%) preferred care in a language other than English (1,273 [43%] in Spanish), and 535 (18%) had a concurrent mental health diagnosis. Multivariable logistic regression of 4,774 patients with complete data revealed that poor appointment adherence (odds ratio [OR] 3.24, 95% CI 2.30-4.57) and/or a positive Patient Health Questionnaire-2 depression screen (OR 1.35, 95% CI 1.12-1.62) had an increased risk of being in the uncontrolled A1C group. Patients with a prescription for antidepressant medication were more likely to be in the controlled group. CONCLUSION: Poor adherence to appointments and presence of depressive symptoms were associated with high A1C values. Interventions can be developed targeting these determinants to improve blood glucose levels.

Monitoring of Recommended Metabolic Laboratory Parameters Among Medicaid Recipients on Second-Generation Antipsychotics in Federally Qualified Health Centers.

BACKGROUND: In 2004, a consensus statement outlining recommended metabolic monitoring for patients prescribed second-generation antipsychotics (SGAs) was published. More than a decade later, suboptimal adherence rates to these recommendations continue to be reported, which could lead to long-term and costly complications. OBJECTIVES: To define the prevalence of appropriately monitored Medicaid patients receiving care at federally qualified health centers (FQHCs) prescribed SGAs. METHODS: This was a retrospective study examining electronic health record and Medicaid claims data to assess the rates of glucose and lipid monitoring for patients prescribed SGAs from January 2014 to August 2016 in a FQHC. Prescription and laboratory claims for patients receiving care at 4 FQHCs were reviewed. Descriptive statistics were used to evaluate the primary outcome. RESULTS: A total of 235 patients were included in the analysis. Patients initiated on SGA therapy (n = 92) had baseline glucose and lipid monitoring rates of 50% and 23%, respectively. The 3-month monitoring rates were 37% for glucose and 26% for lipids, whereas annual rates were 71% and 40%, respectively. Patients continuing SGA therapy (n = 143) had annual glucose and lipid monitoring rates of 67% and 44%. CONCLUSIONS: Medicaid patients at FQHCs initially prescribed SGAs have low baseline and 3-month metabolic monitoring, whereas annual monitoring was comparable to previously published studies. Adults receiving chronic care at a FQHC were more likely to receive glucose monitoring. Those with type 2 diabetes mellitus and/or hyperlipidemia were more likely to receive glucose and lipid monitoring.

Comparison of faculty assessment and students' self-assessment of performance during clinical case discussions in a pharmacotherapy capstone course.

OBJECTIVES: The primary objective of this study was to compare faculty assessment and third year students' self-assessment of performance in clinical case discussions. The secondary objective was to evaluate if student characteristics influence self-assessments. METHODS: This retrospective analysis compared faculty and student self-assessment scores for two clinical case discussions using Spearman's correlation and Wilcoxon's signed ranks test. Chi-squared test was used to compare frequency of faculty and student self-assessments indicating the highest possible rating for the pooled score and for each individual component. The pooled score included three individual components: level of engagement, quality of contribution, and professionalism. RESULTS: Pooled faculty and student self-assessments correlated for both the first (r = 0.41, p < 0.001) and second (r = 0.35; p < 0.001) clinical case discussions. The frequency that faculty and student self-assessment ratings were the highest possible pooled score was similar for both the first (51.3% vs. 44.7%, respectively, p = 0.25) and second (58.6% vs. 47.4%, p = 0.05) clinical case discussions. Student characteristics (age, gender, and grade point average at graduation) did not influence self-assessments. CONCLUSIONS: Students' self-assessment correlated with faculty assessment of performance during clinical case discussions. Increased use of self-assessments for professional development in pharmacy and other healthcare professional curricula should be considered.

Gemfibrozil in Combination with Statins-Is It Really Contraindicated?

Gemfibrozil is a lipid-modifying agent that belongs to the fibric acid derivative class. Fibric acid derivatives activate peroxisome proliferator activated receptor α (PPAR-α). The primary role of these agents in clinical practice is for the management of hypertriglyceridemia. Triglycerides may be reduced by as much as 74 % in some patients. In addition to lowering triglycerides, these agents can also decrease very low-density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C) as well as raise high-density lipoprotein cholesterol (HDL-C). Based on the 2013 ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults and the National Lipid Association, pharmacologic therapy to reduce triglycerides should be considered when triglyceride levels are ≥500 mg/dL. While the use of gemfibrozil has decreased over the years for a variety of reasons, muscle-associated adverse effects is the predominant reason and the one that is most clinically relevant. However, despite these concerns, there are situations in which the use of gemfibrozil in combination with a statin may be necessary. Understanding the metabolism of gemfibrozil and the degree of interaction with the various statins will assist health-care providers to optimize safety when this combination is clinically indicated.

Evaluation of Statin Prescribing for Secondary Prevention in Primary Care Following New Guideline Recommendations.

BACKGROUND: The American College of Cardiology/American Heart Association (ACC/AHA) Guideline on the Treatment of Blood Cholesterol recommends high-intensity statin therapy for most patients with established atherosclerotic cardiovascular disease (ASCVD) versus previously recommended low-density lipoprotein cholesterol targets. The impact of the ACC/AHA guidelines on prescribing patterns in primary care is uncertain. OBJECTIVE: To describe the prescribing habits of statin therapy in primary care patients with ASCVD before and after the ACC/AHA guidelines were published. METHODS: This retrospective observational study evaluated patients with ASCVD who were seen in at least 1 of 8 primary care clinics in the University of Colorado Health system. It received expedited approval by the Colorado Multiple Institutional Review Board. The primary outcome measure was the proportion of patients with established ASCVD prescribed high-intensity statin therapy within 1 year before or after guideline release. RESULTS: In total, 220 patients were included in the analysis with 110 in the before and 110 in the after cohort. For the primary outcome analysis, the rate of high-intensity statin utilization in the before versus after groups was significantly greater (25.5% vs 41.8%, P = 0.01). For ages 76 to 89 years, 36 of 37 and 29 of 30 patients in the before and after groups were receiving moderate- to high-intensity statin therapy (97.3% vs 96.7%, P = 0.99). Subgroup analysis in the after cohort for all ages showed no change in statin therapy for 77% of patients. CONCLUSIONS: High-intensity statin prescribing increased in patients with ASCVD after release of the ACC/AHA cholesterol guidelines. Our data indicate that national evidence-based guidelines may influence clinical practice in very high risk patients.

Claims analysis of hypertension occurrence, severity changes and patterns of antihypertensive use in cancer patients receiving vascular endothelial growth factor inhibitors.

BACKGROUND: Vascular endothelial growth factor inhibitors such as bevacizumab, sorafenib, and sunitinib are utilized in the treatment of multiple cancers. Although these agents are associated with hypertension, there is a lack of evidence describing patterns of antihypertensive use in patients with vascular endothelial growth factor inhibitor-associated hypertension in a non-trial, "real-world" setting. OBJECTIVE: To describe the occurrence and severity of vascular endothelial growth factor inhibitor-associated hypertension, patterns of antihypertensive use and occurrence of cardiovascular complications in a non-trial population, and to describe patterns of initial antihypertensive therapy in patients developing hypertension during treatment with a vascular endothelial growth factor inhibitor. METHODS: This retrospective cohort study utilized claims data from the Medstat MarketScan Commercial Claims and Encounter database to identify patients with claims for a vascular endothelial growth factor inhibitor and a diagnosis of cancer using International Classification of Diseases, 9th Revision, Clinical Modification codes, Healthcare Common Procedure Coding System J-codes and National Drug Codes. The study period encompassed claims from one year before the patient's first claim for a vascular endothelial growth factor inhibitor, and continued through one year after the initial vascular endothelial growth factor inhibitor claim. Patients meeting study criteria were classified into cohorts A1, patients with no hypertension throughout the study period; A2, patients without hypertension at baseline who developed hypertension after starting a vascular endothelial growth factor inhibitor; and cohort B, patients with hypertension prior to receiving a vascular endothelial growth factor inhibitor. We utilized medical and pharmacy claims data to describe the presence of hypertension, its severity, and the occurrence of cardiovascular complications throughout the study period. Initial antihypertensive use in cohort A2 was described. RESULTS: In all, 2177 patients met study criteria and were categorized into cohorts A1 (n = 708), A2 (n = 333) and B (n = 1136). Approximately 32% of patients without hypertension at baseline had claims suggestive for hypertension during the study period. Life-threatening (Grade 4) hypertension increased throughout the study period for cohorts A1, A2, and B, to 3.4%, 10.2%, and 16.4%, respectively (p < 0.001 for all). Claims suggestive of Grade 3 hypertension occurred in more patients in cohort B (45.8%) than in cohort A2 (32.7%, p < 0.001). Cardiovascular complications occurred in 4.7%, 15.6%, and 22.7% of patients in cohorts A1, A2, and B, respectively. Initial antihypertensive agent selection did not impact the occurrence of cardiovascular complications in cohort A2. CONCLUSION: Our study provides valuable insight into non-trial patterns of vascular endothelial growth factor inhibitor-associated hypertension occurrence and severity, and is consistent with prior claims analysis. Identification of optimal strategies to manage vascular endothelial growth factor inhibitor-associated hypertension remain to be clarified with the advent of more comprehensive data sets.

Statins for the primary prevention of cardiovascular disease in the elderly.

OBJECTIVE: The objective is to review the evidence evaluating the efficacy of statin therapy for primary prevention of cardiovascular (CV) disease in the elderly. DATA SOURCES: A literature search of MEDLINE and PubMed (1966-January 2013) using the terms HMG-CoA reductase inhibitor, statin, primary prevention, elderly, and geriatrics was performed. The search was limited to clinical trials, meta-analyses, and subanalyses, including primary prevention patients. Bibliographies of selected articles were examined to identify additional clinical trials. STUDY SELECTION: Fourteen clinical trials, subanalyses, and meta-analyses were reviewed. A total of seven clinical trials and subanalyses evaluating statin therapy versus placebo in the elderly primary prevention patients with a primary endpoint of hard coronary heart disease were included. DATA EXTRACTION: Data collected from the clinical trials and subanalyses included number of elderly patients randomized, therapy, duration of follow-up, and the incidence of coronary events. DATA SYNTHESIS: The average annual rates of first CV event increases as patients age. There is strong evidence that supports the use of statins for secondary prevention; although primary prevention, specifically in the elderly, is less defined. This paper reviews the literature specifically for primary prevention, for which the results have shown a trend toward decreased first occurrence of coronary heart disease with statin therapy in elderly patients. CONCLUSION: Statin therapy should be considered as a primary prevention therapy against coronary disease for elderly patients. Evidence-based clinical benefits are seen in this patient population. However, clinical judgment and consideration of comorbidities that may impact life expectancy should be assessed to determine appropriateness for individual patients.
