An individualized approach to residency preparation for fourth professional year pharmacy students.

INTRODUCTION: The objective of this study was to evaluate the impact of an individualized residency preparation program and faculty mentorship on student preparedness for pursuing residency training and their ability to successfully match with a postgraduate year one (PGY1) residency position. METHODS: This prospective cohort enrolled fourth professional year pharmacy students from August 2016 to March 2017. Students participated in a faculty-designed residency preparation program, were assigned faculty mentors, and were provided with several residency preparation resources. The primary outcome was change in the median overall perceived level of preparedness, as measured by pre- and post-residency preparation program surveys. A key secondary end point was the correlation between obtaining a PGY1 residency position and the number of residency preparation sessions attended. RESULTS: Fifty-two students participated in the residency preparation program. The median overall perceived level of preparedness increased following the preparation program. Of the 52 students participating, 37 attended over half of the program sessions. Twenty-one of the 37 (56.8%) students participating in more than half of the sessions matched with a PGY1 program compared to three out of 15 (20%) students participating in fewer than half the sessions. Additionally, students reported value in mock interviews, faculty mentorship, and institution-specific residency preparation guidance delivered via a workbook. CONCLUSIONS: Participation in an individualized residency preparation program with faculty mentorship and institution-specific guidance improves the perceived level of preparedness for students pursuing residency training. High attendance at sessions, along with other factors, may contribute to a higher rate of success.

Direct oral anticoagulants for stroke prevention in atrial fibrillation: treatment outcomes and dosing in special populations.

BACKGROUND: To review data from the pivotal phase III trials evaluating the efficacy and safety of direct oral anticoagulants (DOACs) versus warfarin for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF), and to summarize the major findings with regards to patient subgroups that are at an increased risk for stroke or bleeding. METHODS: A PubMed literature search (January 2009 to January 2017) was performed using the terms 'dabigatran', 'rivaroxaban', 'apixaban', 'edoxaban', 'atrial fibrillation', 'RE-LY', 'ROCKET AF', 'ARISTOTLE', and 'ENGAGE AF-TIMI 48'. All primary publications and secondary analyses in special populations at increased risk of stroke or bleeding from the pivotal phase III clinical trials were evaluated. RESULTS: Available secondary analyses indicate no treatment interactions with regards to stroke or systemic embolic event (SEE) prevention for any of the DOACs in the patient subgroups, including patients with advanced age, impaired renal function, diabetes, prior stroke, concomitant antiplatelet therapy, heart failure, prior stroke, history of hypertension, myocardial infarction (MI), coronary artery disease, and peripheral artery disease (PAD). Although higher bleeding incidence was reported with dabigatran and rivaroxaban in patients aged 75 years and over with apixaban in patients with diabetes, and with rivaroxaban in patients with previous MI or PAD, no changes in dosing are recommended. CONCLUSIONS: Overall, results of secondary analyses indicate that the recommended dosing strategy for each of the DOACs produces a consistent anticoagulant effect across a diverse patient population, including those at increased risk of stroke or bleeding.

Effect of a Rivaroxaban Patient Assistance Kit (R-PAK) for Patients Discharged With Rivaroxaban: A Randomized Controlled Trial.

Background: The combination of poor health literacy and a complex dosing regimen/transition for rivaroxaban in venous thromboembolism (VTE) treatment may increase the likelihood of negative clinical outcomes secondary to nonadherence. Objective: The aim was to determine if a Rivaroxaban Patient Assistance Kit (R-PAK) given at hospital discharge increases proper dose transition and overall patient adherence. Methods: This prospective, randomized, controlled trial was conducted at an 859-bed academic medical center. Patients were randomized into 2 groups. In the treatment group, patients received the R-PAK with counseling at discharge, whereas patients in the control group received discharge counseling alone. In addition, patients were contacted after 21 days of therapy to assess dose transition, adherence, satisfaction, and safety. The primary outcome was percentage of patients who properly transitioned to rivaroxaban once daily on day 22. Results: Twenty-five patients were enrolled; 12 received an R-PAK, whereas 13 comprised the control group. No difference in the baseline assessment of health literacy status was noted (P = 1.00). Proper transition to daily administration on day 22 was no different between the groups (P = .891). Adherence was reported in 99.8% of R-PAK patients and 97.65% of control patients (P = .074). Side effects were rarely reported. Conclusions: The use of an R-PAK for the treatment of VTE was not associated with an improvement in transition to daily administration; however, both groups had high rates of overall adherence. Pharmacist counseling/education was provided in both groups and is an important component to include in any patient discharge, especially for medications with dose transitions.

Comparison of hospital length of stay in patients treated with non-vitamin K oral anticoagulants or parenteral agents plus warfarin for venous thromboembolism.

OBJECTIVES: Existing research comparing hospital length of stay for patients treated with non-vitamin K oral anticoagulants or parenteral bridging to warfarin has been conducted primarily with the agent rivaroxaban. The objective of this study was to compare hospital length of stay between patients initiated on the non-vitamin K oral anticoagulants, apixaban or rivaroxaban, and patients initiated on parenteral anticoagulation agents plus warfarin for the treatment of venous thromboembolism. METHODS: A retrospective cohort study was conducted at an 859-bed, not-for-profit, teaching hospital. Adult patients admitted for a primary diagnosis of venous thromboembolism between 1 November 2012 and 31 August 2015 and treated with apixaban or rivaroxaban or a parenteral anticoagulant plus warfarin were included in the study. Eligible patients were identified using International Classification of Diseases, Ninth Revision codes for a primary diagnosis of acute thromboses and emboli and medication administration record data. Individuals using anticoagulation therapy prior to admission, released from the emergency department, or treated with thrombectomy or fibrinolytic therapy were excluded. RESULTS: A total of 152 patients were included in this study. Patient characteristics, including renal function, were similar between study arms. Venous thromboembolism treatment with apixaban or rivaroxaban compared to a parenteral anticoagulant plus warfarin was associated with a reduced hospital length of stay (2.63 vs 5.33 days; p < 0.05) and decreased total hospital cost adjusted to 2015 dollars (US$21,694 vs US$38,851; p = 0.013). CONCLUSION: These results suggest that treatment with a non-vitamin K anticoagulant may significantly reduce hospital length of stay and total hospital cost compared to a parenteral anticoagulant plus warfarin for patients admitted for venous thromboembolism.

Edoxaban: A Comprehensive Review of the Pharmacology and Clinical Data for the Management of Atrial Fibrillation and Venous Thromboembolism.

Historically, vitamin K antagonists have been the only class of oral anticoagulants available. Despite our experience with warfarin over the past 60 years, its use is associated with several pharmacokinetic and clinical disadvantages including unpredictable dosing, frequent monitoring, and delayed onset and offset. Edoxaban, an oral direct Xa inhibitor, may provide clinicians with an additional option in patients requiring chronic anticoagulation. This review examines the pharmacology and clinical data of edoxaban as a therapeutic alternative.

Conception of a Personalized Medication Adherence Discharge Kit for Rivaroxaban.

Purpose: Due to a lack of necessary monitoring with rivaroxaban, patients have fewer opportunities for education, adherence reinforcement, and follow-up. If rivaroxaban is taken incorrectly, patients are at increased risk for adverse events. The objective was to create personalized rivaroxaban patient adherence kits (R-PAKs) to enhance successful transition from 15 mg twice daily to 20 mg once daily on day 22 of venous thromboembolism (VTE) treatment. Summary: A review of rivaroxaban drug information and existing medication adherence tools was completed to increase understanding of ways to improve adherence. Clinical pharmacists identified several concerns the R-PAK should address, including patient understanding of correct dose, administration timing, serious adverse effects, and importance of compliance, along with loss to follow-up by a health care provider. In the pilot phase, 100 R-PAKs were created. Each kit includes an educational handout describing adverse effects, administration, and monitoring; a reminder card with dosing information, date to transition, and emergency contact information; and a personalized 28-day pill organizer containing customized dividers to correlate with the first 21 days of treatment. Color-coded stickers denote the first day of starting twice-daily therapy upon discharge and the day of transition to once-daily dosing. The items were distributed in tote bags at discharge along with pharmacist education. Conclusion: The R-PAKs are being used at a community teaching hospital for patients newly diagnosed with VTE who are discharged on rivaroxaban. The concept of a personalized medication box could be modified for any medication that requires high compliance or dose transitions.

The Use of Edoxaban in Patients with Nonvalvular Atrial Fibrillation and Venous Thromboembolism: A Pharmacist's Perspective.

Until 2010, the vitamin K antagonist warfarin was the only available oral anticoagulant for the prevention of stroke or systemic embolic events (SEE) in patients with nonvalvular atrial fibrillation (NVAF) and the treatment of venous thromboembolism (VTE) in the United States. Despite its proven efficacy, the use of warfarin is limited by numerous disadvantages, including a delayed onset of action and variable efficacy resulting from interactions with genetic and environmental factors. Consequently, optimal anticoagulation with warfarin requires dose adjustments based on frequent monitoring. In contrast to warfarin, direct oral anticoagulants (DOACs) including dabigatran, rivaroxaban, apixaban, and edoxaban have predictable pharmacokinetic profiles, few drug-drug interactions, no known interactions with food, and can be administered at fixed doses without the requirement for routine monitoring. All DOACs have received US Food and Drug Administration (FDA) approval for the prevention of stroke or SEE in patients with NVAF and the treatment of VTE based on phase 3 trials demonstrating that they are at least as efficacious as warfarin. In addition, the incidence of clinically relevant bleeding associated with DOACs is comparable to or lower than with warfarin. In this article, the preclinical and clinical data that led to the FDA approval of once-daily edoxaban in January 2015 are presented. Furthermore, practical considerations for edoxaban use including dosing recommendations, transitions of care, reversal of anticoagulation, precautions, contraindications, and cost-effectiveness are discussed. Edoxaban is an important addition to oral anticoagulation options available for the therapeutic management of patients with NVAF or VTE.

Utilization of coagulation assays in clinical therapeutics.

With the emergence of new anticoagulants, clinicians need a thorough understanding of coagulation assays. Various laboratory assays exist to measure the effectiveness of anticoagulants. Coagulation assays are the primary method for measuring the effectiveness of anticoagulants; therefore, a comprehensive understanding of the various assays is critical to interpret the results appropriately. Coagulation test results can be affected by multiple factors including diseases, drugs, and genetic variations. This article reviews the indications, limitations, and interpretation of coagulation assays.

Key articles and guidelines in the management of acute coronary syndrome and in percutaneous coronary intervention: 2012 update.

More than 1 million people in the United States experience an acute coronary syndrome (ACS) every year, and almost 600,000 undergo percutaneous coronary intervention (PCI) for treatment of cardiovascular disease. There is a large amount of evidence-based literature to guide appropriate management of these patients. There have been a number of advances in the treatment of these patients over the last several years. Due to the large amount of rapidly available literature concerning the care of patients with ACS or undergoing PCI, clinicians can often find it difficult to keep up with the information needed for optimizing care of these patients. Therefore, we provide the second update to the first compiled bibliography of key articles and guidelines relative to patients with ACS published in Pharmacotherapy in 2004. The initial update was published in Pharmacotherapy in 2007 and also included bibliographies concerning management of patients undergoing PCI. A number of guidelines and practice-changing literature have been published since the update in 2007. Specific areas included in this review are updated summaries of clinical practice guidelines and clinical trials of anticoagulants, antiplatelets, platelet aggregation testing, pharmacogenomics testing in patients taking clopidogrel, clopidogrel loading dose comparisons, clopidogrel and proton pump inhibitor drug interactions, the impact of bleeding in ACS, and statins. As with previous versions of this document, we hope that this compilation will serve as a resource for pharmacists, physicians, nurses, residents, and students responsible for the care of patients with coronary heart disease.

Impact of a student-supported pharmacy assessment program on venous thromboembolism prophylaxis rates in hospitalized patients.

OBJECTIVES: To determine if the addition of a student-supported venous thromboembolism risk assessment strategy could improve rates of venous thromboembolism prophylaxis at a community teaching hospital. METHODS: After receiving education and training on venous thromboembolism risk assessment, students assessed patients and recommended therapy in a 493-bed community teaching hospital over 5 weeks. Both the quantity and quality of venous thromboembolism prophylaxis were measured and compared to a baseline rate. RESULTS: One hundred three recommendations were made to physicians with a 41% acceptance rate. Compared to previous rates, the percentages of patients receiving "any," "suitable," and "optimal" venous thromboembolism prophylaxis increased from 70.5% to 82.7% (p = 0.0005), 64.4% to 75.9% (p = 0.0022), and 56.3% to 68.5% (p = 0.0022), respectively. CONCLUSIONS: A student-supported venous thromboembolism risk assessment strategy resulted in an increase in venous thromboembolism prophylaxis rates and could be used as a model for other institutions to integrate students into population-based care.

Pharmacologic therapy for intermittent claudication.

Peripheral artery disease, defined as atherosclerosis in the lower extremities, affects nearly 8.5 million people in the United States. Due to the frequent asymptomatic manifestation of peripheral artery disease, diagnosis may be delayed and its true incidence underestimated. However, some patients may experience aching pain, numbness, weakness, or fatigue, a condition termed intermittent claudication. Peripheral atherosclerosis is associated with cardiovascular risk and physical impairment; therefore, treatment goals are aimed at decreasing cardiovascular risk, as well as improving quality of life. Little debate exists regarding the management of cardiovascular risk reduction, which consists of both antiplatelet therapy and risk factor modification. Despite recently published guidelines, the treatment of intermittent claudication is less well established and the management remains controversial and uncertain. Exercise remains the first-line therapy for intermittent claudication; however, pharmacologic treatment is often necessary. Although only two prescription drugs have been approved by the U.S. Food and Drug Administration for the treatment of intermittent claudication, several supplements and investigational agents have been evaluated. Therapeutic optimization should balance the anticipated improvements in quality of life with the potential safety risks.

Management of chronic nonmalignant pain with nonsteroidal antiinflammatory drugs. Joint opinion statement of the Ambulatory Care, Cardiology, and Pain and Palliative Care Practice and Research Networks of the American College of Clinical Pharmacy.

Chronic nonmalignant pain is a major burden on the health care system in the United States. Frequently, nonsteroidal antiinflammatory drugs (NSAIDs) are used to assist in the management of various chronic pain syndromes. Although evidence is accumulating on the potential toxicities associated with NSAIDs, clear recommendations are lacking to guide the appropriate use of these drugs. Equivocal data, especially with respect to cardiovascular risk, further confuse a clear treatment pathway when assessing pharmacotherapy. Originally, cyclooxygenase selectivity appeared to be a determining factor in choosing an agent because of the presumed lack of effect on the cardiovascular and gastrointestinal renal systems. This theory, however, was recently dispelled. To provide guidance on the selection of an NSAID for various chronic pain syndromes, members of the Ambulatory Care, Cardiology, and Pain and Palliative Care Practice and Research Networks of the American College of Clinical Pharmacy evaluated evidence-based use of NSAIDs for frequently encountered pain syndromes, with special focus on the adverse effects of this class of agents.

Cardiovascular risks of cyclooxygenase inhibition.

Millions of patients use nonsteroidal antiinflammatory drugs (NSAIDs) for relief of arthritic pain. Although NSAIDs reduce pain, their use has been linked to gastroduodenal complications. Selective inhibition of the cyclooxygenase (COX)-2 enzyme appeared to offer patients similar pain relief with an improved adverse-effect profile. However, accumulating experiences have raised concerns regarding the cardiovascular toxicities of the selective COX-2 inhibitors. Although selective COX inhibitors provide more gastrointestinal protection than NSAIDs, the unbalanced inhibition of prostaglandins may promote cardiovascular complications. Variability in study designs and inconsistency in results have made the evaluation of NSAID and COX-2 inhibitor safety very difficult, creating confusion among health care practitioners. We examine the pharmacologic and clinical evidence that defines the cardiovascular risk associated with COX inhibition.

Effect of a clinical pharmacy education program on improvement in the quantity and quality of venous thromboembolism prophylaxis for medically ill patients.

OBJECTIVE: The American College of Chest Physicians (ACCP) recommends unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH) for prevention of venous thromboembolism (VTE) in medically ill patients. Despite these recommendations, a previous analysis at our institution revealed a low utilization of VTE prophylaxis in medically ill patients. Our objective was to evaluate the effects of a pharmacy-driven education program on the quantity and quality of VTE prophylaxis in medically ill patients. METHODS: An educational program focusing on the importance of VTE prophylaxis in medically ill patients was developed by clinical pharmacists and presented to nurses, pharmacists, and physicians in a 493-bed community teaching hospital. The educational program was conducted between June 2002 and June 2003 and consisted of in-service presentations, newsletters, and quality assurance presentations on VTE prophylaxis. The educational program focused on 4 main points: (1) hospitalized medically ill patients are at risk for developing VTE, (2) how to identify medically ill patients who require VTE prophylaxis, (3) the fact that VTE prophylaxis is currently underutilized in medically ill patients, and (4) appropriate VTE prophylaxis strategies for medically ill patients. A posteducation retrospective chart review was performed in medically ill patients with discharge dates between October 2003 and March 2004, and these posteducation medical chart data were compared with the results from a preeducation analysis of patents with discharge dates from January 2001 to March 2002. Data collection included patient demographics, VTE risk factors, and use and type of VTE prophylaxis. RESULTS: The posteducation retrospective chart review was performed for 297 medically ill patients with discharge dates between October 2003 and March 2004 and for 344 preeducation patients discharged between January 2001 and March 2002. Patient demographics and primary diagnoses were similar between the preeducation and posteducatin groups. The mean number of risk factors per patient in the preeducation group was 2.53 +/- 0.96 versus 2.38 +/- 0.88 in the posteducation group (P=0.626). Pharmacy education was associated with an increase in the utilization of any VTE prophylaxis (43% in the preperiod vs. 58% in the postperiod; P <0.001). Prophylaxis judged to be suitable (UFH 5,000 units twice daily, or UFH 5,000 units 3 times daily, or LMWH once daily), increased from 38% in the preeducation period to 49% in the posteducation period, P=0.006). Prophylaxis judged to be optimal (UFH 3 times daily or LMWH once daily) increased from 11% to 44% of patients, P <0.001). CONCLUSIONS: A hospital-wide clinical pharmacy education program was associated with significant improvement in the quantity and quality of VTE prophylaxis in medically ill patients in a community teaching hospital.

Drug-eluting stents: a mechanical and pharmacologic approach to coronary artery disease.

Coronary artery disease is the largest killer of men and women in the United States and costs the health care system billions of dollars annually. Several advances in both mechanical and pharmacologic treatment of coronary artery disease have occurred in recent decades. Mechanically, percutaneous coronary intervention is commonly used to treat coronary atherosclerosis. This approach has dramatically reduced both morbidity and mortality for patients with different levels of severity of coronary artery disease. However, percutaneous coronary intervention is limited by restenosis, which is an increase in growth of the intimal layer of the vessel wall. Despite the introduction of intracoronary stents and the addition of systemic pharmacotherapy, restenosis still affects a significant number of patients. The new technology of drug-eluting stents combines mechanical and pharmacologic approaches to prevent restenosis. Various types of these stents exist in different stages of development; several have been shown to prevent or reduce intimal growth after stent deployment. An understanding of how this combined mechanical and pharmacologic approach reduces restenosis requires consideration of complex issues in pathophysiology and pharmacology.
