Using pharmacy technicians and electronic health record capabilities to improve outcomes for patients with cardiovascular disease.

OBJECTIVE: This study aimed to compare lipid and blood pressure (BP) control before and after implementing a certified pharmacy technician (CPhT) protocol that optimized electronic health record (EHR) capabilities and shifted work from clinical pharmacy specialists (CPSs) to CPhT. SETTING: Kaiser Permanente Colorado's pharmacist-managed cardiac risk reduction service (which manages dyslipidemia, hypertension, and diabetes for all patients with atherosclerotic cardiovascular disease). PRACTICE DESCRIPTION: In 2019, a protocol that optimized EHR capabilities and allowed work to be offloaded from CPS to CPhT was implemented. Filtered views within the EHR were created that bucketed patients with specific lipid results criteria. The CPhT protocol provided guidance to CPhT on determining whether patients were at low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein (non-HDL) goals, on appropriate statin intensity, adherent to medications, and whether the most recent BP was controlled. The CPhT notified CPS of uncontrolled patients who would assess and manage these patients, as necessary. The CPhT notified controlled patients of their results. PRACTICE INNOVATION: Data on the outcomes of incorporating pharmacy technicians to support CPS clinical activities in ambulatory clinical pharmacy are limited. EVALUATION DETHODS: This retrospective study compared a "Pharmacist-Driven" (index date: January 1, 2016) with a "Tech-Enhanced" (index date: January 1, 2019) group. The primary outcome was the proportion of patients at all goals defined as LDL-C < 70 mg/dL, non-HDL < 100 mg/dL, and BP < 140/90 mm Hg at 1 year after the index dates. RESULTS: There were 6813 patients included (mean age: 70.2 ± 11.1 years, 71.4% male): 3130 and 3683 in the "Pharmacist-Driven" and "Tech-Enhanced" groups, respectively. The proportion of patients who attained LDL-C, non-HDL, and BP goals was higher in the "Tech-Enhanced" group (51.1% vs. 39.7%, P < 0.001) than the "Pharmacist-Driven" group. CONCLUSION: A protocol integrating EHR decision support and CPhTs enabled work to shift to from CPS to CPhT and improved clinical outcomes.

Fixed-Dose Combination Medications for Treating Hypertension: A Review of Effectiveness, Safety, and Challenges.

PURPOSE OF REVIEW: To summarize the recent evidence on the effectiveness and safety of antihypertensive fixed-dose combination (FDC) medications, and to describe the facilitators and barriers to implementing FDCs in US clinical practice. RECENT FINDINGS: Recent clinical practice guidelines include FDC use for treating high BP. Clinical trials in recent years support the use of antihypertensive FDCs including low-dose triple- and quadruple-therapy FDCs. Initiating a low-to-standard dose dual-therapy FDCs showed better BP control than initiating treatment with a standard-dose monotherapy, and triple-therapy FDCs produced better BP control rates than dual-therapy FDCs. Retrospective cohort studies showed that FDCs are associated with increased medication adherence, reduced clinical inertia, decreased time to BP control, and improved cardiovascular outcomes. We further discussed barriers and facilitators of wider implementation of antihypertensive FDCs in clinical practice. FDC treatment for hypertension is not commonly used despite historical and recent data which support the effectiveness, safety, and benefits of FDCs. Simplified and protocolized treatment algorithms, team-based care, shared decision-making principles are crucial to successful utilization and implementation of FDC in clinical practice.

Transthyretin Amyloid Cardiomyopathy Risk Evaluation in a Cohort of Patients With Heart Failure.

Introduction Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive, infiltrative form of heart failure (HF). Nevertheless, ATTR-CM is a largely underrecognized and misdiagnosed condition. This study's objective was to develop an efficient model to assess the chance of ATTR-CM in patients with HF. Methods This was an observational study of patients with HF who had a confirmed diagnosis of ATTR-CM and those with HF but without known ATTR-CM between January 1, 2019, and July 1, 2021. Patient characteristics were extracted from administrative and claims electronic databases and compared between the groups. A propensity score for having ATTR-CM was modeled. Samples of 50 control patients with the highest and lowest propensity scores were adjudicated to assess whether further workup to evaluate for ATTR-CM was warranted for each patient. The sensitivity and specificity of the model were calculated. Results Thirty-one patients with confirmed ATTR-CM and 7620 patients without known ATTR-CM were included in the study. Patients with ATTR-CM were more likely to be Black and to have atrial flutter/fibrillation, cardiomegaly, HF with preserved ejection fraction, pericardial effusion, carpal tunnel syndrome, joint disorders, and lumbar spinal stenosis and to use a diuretic (all p < 0.05). A propensity model with 16 inputs was developed (c-statistic = 0.875). The model's sensitivity and specificity were 71.9% and 95.2%, respectively. Conclusion The propensity model developed in this study provided an efficient means for identifying patients with HF who are more likely to have ATTR-CM and may warrant further workup.

Switching from Biologic to Biosimilar Products: Insight from an Integrated Health Care System.

Biologics are indicated for the treatment of a wide range of conditions and have transformed care in several therapeutic areas; however, they are expensive for both health care systems and patients. The use of biosimilars, which are approved by the US Food and Drug Administration as being "highly similar" to the originator biologic, has the potential to change the health care landscape in the biologic space through considerable cost savings for both payors and patients. With the introduction of biosimilars, organizations are increasingly evaluating how to switch patients from originator biologics to biosimilars. While published studies have evaluated the outcomes of patients switched from originator biologics to biosimilars, there are few publications describing the process health care systems have used to adopt and switch patients to biosimilars. Since 2016, Kaiser Permanente Colorado (KPCO) has undertaken several biosimilar switches starting with the first biosimilar introduced to the market, filgrastim, and has been able to successfully switch 91.8% of patients receiving infliximab, 99.8% receiving rituximab, and 100% receiving filgrastim, trastuzumab, and bevacizumab originator biologics to their respective biosimilars. In an effort to support other health care systems and provide a framework for implementing biosimilar switches, the purpose of this paper is to describe the biosimilar switch model and share learnings from the KPCO experience.

Clinical outcomes of dabigatran use in patients with non-valvular atrial fibrillation and weight >120 kg.

BACKGROUND: Patients with obesity were underrepresented in studies evaluating the safety and effectiveness of direct oral anticoagulants (DOAC) in patients with non-valvular atrial fibrillation (NVAF). This study compared clinical outcomes in patients with NVAF and weighing >120 kg and ≤120 kg who were receiving dabigatran. MATERIALS AND METHODS: This retrospective, matched, longitudinal cohort study included patients from three integrated healthcare delivery systems. Patients ≥18 years of age with NVAF were included if between September 1, 2016 and June 30, 2019 they received dabigatran. Patients >120 kg and ≤120 kg were matched up to 1:6 on age, sex, and CHA2DS2-VASc score. Data were extracted from administrative databases. The primary outcome was a composite of ischemic stroke, clinically-relevant bleeding, systemic embolism, and all-cause mortality. Multivariable regression analyses were performed. RESULTS: 777 and 3522 patients >120 kg and ≤120 kg, respectively, were matched. The >120 kg group tended to be younger with a higher burden of chronic disease. There was no difference between groups in the composite outcome (adjusted hazard ratio [AHR] 1.10, 95% confidence interval 0.89-1.37) or individual components of the composite. A subanalysis of clinically-relevant bleeding identified that patients >120 kg were at a greater risk of gastrointestinal bleeding (AHR 1.44, 95% CI 1.01-2.05). CONCLUSIONS: In patients with NVAF and >120 kg, dabigatran use was associated with a small increased risk of gastrointestinal bleeding but no differences in stroke, mortality or clinically-relevant bleeding. These findings suggest that dabigatran use is reasonable in patients with NVAF and weight >120 kg.

The risk for significant creatine kinase elevation with statins.

BACKGROUND: The HMG-CoA reductase inhibitors (statins) are effective for reducing long-term cardiovascular morbidity and mortality in both primary and secondary prevention. The most serious adverse reaction is significant elevation of creatine kinase (CK) leading to rhabdomyolysis. The incidence of CK elevation is low in randomized, controlled trials. The rate may be higher in 'real-world', less controlled settings. Data on the risks of statin-associated rhabdomyolysis in 'real-world' practice settings are limited. OBJECTIVE: The aim of this study was to examine the risk for CK elevation among statin users in a clinical practice setting. Potential risk factors were identified and evaluated to quantify the risk for CK elevation with statins. METHODS: This case-control study was conducted at Kaiser Permanente Colorado. Patients with prescriptions for lovastatin or simvastatin between 1 January 1999 and 30 June 2006 were identified. Cases (n = 183), i.e. patients with a CK > or =10x the upper limit of normal (ULN) while receiving a statin during this time period, were each matched on the date of statin purchase to ten control patients (n = 1830) without CK > or =10x ULN while receiving a statin. Multivariate, conditional logistic regression was used to assess the associations between the statin, statin dose, demographic, co-morbidity, laboratory, and medication factors potentially associated with CK >or =10x ULN. RESULTS: he mean (SD) age of patients was 64.9 (11.5) years and 56.9% were male. Overall, simvastatin use was associated with a higher likelihood for CK > or =10x ULN than lovastatin (adjusted odds ratio [OR] 4.6; 95% CI 1.1, 12.4). Using simvastatin 40 mg daily as the referent, and in the absence of interacting medications, only simvastatin 80 mg was associated with a higher likelihood for CK > or =10x ULN (OR 2.7; 95% CI 1.1, 6.9). In the presence of interacting medications, all doses of simvastatin and only lovastatin 80 mg were associated with a higher likelihood for CK > or =10x ULN. CONCLUSION: In this study, simvastatin was associated with a higher likelihood for CK > or =10x ULN than lovastatin. High-dose simvastatin, in particular, appears to confer a greater risk than lower doses of either simvastatin or lovastatin.

Incidence of hemorrhage among anticoagulated patients receiving antiplatelet therapy after percutaneous coronary intervention.

This study aimed to compare major hemorrhage rates among patients receiving warfarin, acetylsalicylic acid (ASA), and clopidogrel to those receiving ASA and clopidogrel following percutaneous coronary intervention with stent implantation. This retrospective cohort study identified patients with stents implanted between September 1, 2003 and December 31, 2006. Patients treated with warfarin, ASA, and clopidogrel within 30 days of hospital discharge (Triple Therapy group) were matched by age, sex, and stent type to patients treated with ASA and clopidogrel (Dual Therapy group). Outcomes included the incidence rates of major hemorrhage and major adverse coronary events (MACE) within 12 months of stent implantation. There were 175 and 339 patients in the Triple Therapy and Dual Therapy groups, respectively. There were 25 (14.3%) and 10 (3.0%) major hemorrhages in the Triple Therapy and Dual Therapy groups, respectively (OR 9.0; 95% CI, 3.1-26.1). Patients in the Triple Therapy group had a greater likelihood of MACE compared to patients in the Dual Therapy group (OR 2.0; 95% CI 1.1-3.8). Post-stent treatment with warfarin, ASA, and clopidogrel was associated with a substantially greater likelihood of major hemorrhage than treatment with ASA and clopidogrel alone.

Importance of therapy intensification and medication nonadherence for blood pressure control in patients with coronary disease.

BACKGROUND: Despite the importance of blood pressure (BP) control in secondary prevention, a significant proportion of patients with coronary disease have uncontrolled BP. METHODS: This retrospective cohort study of patients with coronary disease (N = 10 447) evaluated the impact of medication nonadherence and therapy intensification on reaching target BP goals. Medication adherence was calculated as the proportion of days covered for filled prescriptions of antihypertensive medications. Therapy intensification included dosage increase or increase in number of antihypertensive medications. The primary outcome was uncontrolled systolic BP (SBP) over time, using a latent class model that incorporated longitudinal SBP data and assigned patients to SBP trajectory groups. Multivariable regression evaluated the association between medication nonadherence (ie, proportion of days covered, <0.80) and therapy intensification with SBP control over time, with adjustment for demographics and clinical characteristics. RESULTS: Three SBP trajectory groups were identified: (1) patients with BP that remained controlled (ie, SBP,

Trends in high intensity statin use among secondary prevention patients 76 years and older.

BACKGROUND: High intensity statin therapy (HIST) is the gold standard therapy for decreasing the risk of recurrent atherosclerotic cardiovascular disease (ASCVD); however, little is known about the use of HIST in older adults with ASCVD. OBJECTIVES: The aim of this cross-sequential study was to determine trends in statin intensity in older adults over a 10-year timeframe. METHODS: The study was conducted in an integrated healthcare delivery system. Patients were 76 years or older with validated coronary ASCVD. Data were collected from administrative databases. Statin intensity level was assessed in eligible patients on January 1st and July 1st from January 1, 2007 to December 31, 2016. RESULTS: Overall, a total of 5,453 patients were included with 2,119 (38.9%) and 3,334 (61.1%) categorized as HIST and Non-HIST, respectively. Included patients had a mean age of 79.8 years and were primarily male and white and had a cardiac intervention. The rate of HIST use increased from 14.5% to 41.3% over the study period (p<0.001 for trend). Conversely, the rates of moderate and low intensity statin use decreased from 61.8% and 9.8% to 41.2% and 4.8%, respectively (both p<0.001 for trend). Similar trends were identified for females and males. CONCLUSIONS: The percentage of patients with ASCVD 76 years and older who received HIST substantially increased from 2007 to 2016. This trend was identified in both females and males. Future comparative effectiveness research should be conducted in this patient population to examine cardiac-related outcomes with HIST and Non-HIST use.

Value of Pharmacy Students Performing Population Management Activity Interventions as an Advanced Pharmacy Practice Experience.

Objective. To assess the value of an advanced pharmacy practice experience in which students engaged in population health management (PHM) activities for a managed care setting. Methods. Students were provided with a list of patients, trained on the requirements for each PHM activity and completed them independently. The students reviewed the electronic record for each patient on their list to identify those who were non-adherent to dual antiplatelet therapy (DAPT) within one year of coronary stent placement, non-adherent to beta blockers (BB) within six months post-acute myocardial infarction, or with renal dysfunction and requiring dose adjustment of lipid-lowering therapy. Students coded each intervention based on predefined categories such as patient education, medication discontinuation, or medication reconciliation, and then if necessary were reviewed with the pharmacy preceptor. The primary investigator determined the intervention to be either actionable or non-actionable. The primary outcome was the proportion and type of interventions made by each student. The secondary outcome was clinical pharmacist time offset. A retrospective, data-only pilot study was conducted to determine the outcomes from the program over four years. Results. Forty-six students made 3,774 interventions over the study period, 37% of which were categorized as actionable. The most common actionable interventions were providing patient education (52%), verifying prescription adherence (23%), and medication therapy adjustment (10.5%). Over the study period, an estimated 765.6 hours of clinical pharmacist time was offset, or approximately 191.4 hours per academic year. Conclusion. This study demonstrated that a population health management approach can be used successfully within an APPE. This approach can result in offset pharmacist time for precepting organizations, while offering meaningful clinical interventions for patients and learning opportunities for students.

Medication nonadherence is associated with a broad range of adverse outcomes in patients with coronary artery disease.

BACKGROUND: Little is known about the effect of nonadherence among patients with coronary artery disease (CAD) on a broad spectrum of outcomes including cardiovascular mortality, cardiovascular hospitalizations, and revascularization procedures. METHODS: This was a retrospective cohort study of 15,767 patients with CAD. Medication adherence was calculated as proportion of days covered for filled prescriptions of beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, and statin medications. Multivariable Cox regression assessed the association between medication nonadherence as a time-varying covariate and a broad range of outcomes, adjusting for demographics and clinical characteristics. Median follow-up was 4.1 years. RESULTS: Rates of medication nonadherence were 28.8% for beta-blockers, 21.6% for ACE inhibitors, and 26.0% for statins. In unadjusted analysis, nonadherence to each class of medication was associated with higher all-cause and cardiovascular mortality. In multivariable analysis, nonadherence remained significantly associated with increased all-cause mortality risk for beta-blockers (hazard ratio [HR] 1.50, 95% CI 1.33-1.71), ACE inhibitors (HR 1.74, 95% CI 1.52-1.98), and statins (HR 1.85, 95% CI 1.63-2.09). In addition, nonadherence remained significantly associated with higher risk of cardiovascular mortality for beta-blockers (HR 1.53, 95% CI 1.16-2.01), ACE inhibitors (HR 1.66, 95% CI 1.26-2.20), and statins (HR 1.62, 95% CI 1.124-2.13). The findings of increased risk associated with nonadherence were consistent for cardiovascular hospitalization and revascularization procedures. CONCLUSIONS: Nonadherence to cardioprotective medications is common in clinical practice and associated with a broad range of adverse outcomes. These findings suggest that medication nonadherence should be a target for quality improvement interventions to maximize the outcomes of patients with CAD.

Key articles and guidelines in the management of hypertension: 2008 update.

Hypertension remains a major risk factor for cardiovascular disease. The optimal choice of pharmacologic and nonpharmacologic treatment regimens is based on a plethora of published literature. This compilation is the initial update to the Key Articles and Guidelines in the Management of Hypertension authored by members of the Cardiology Practice and Research Network of the American College of Clinical Pharmacy, which appeared in Pharmacotherapy in 2004. We present synopses of clinical trials, meta-analyses, clinical practice guidelines, and other pertinent literature published between May 2003 and June 2007.

Relationship between haemoglobin A1C values and recurrent cardiac events: A retrospective, longitudinal cohort study.

OBJECTIVE: This study set out to analyse the impact of baseline glycosylated haemoglobin A1c (HbA1c) values on the incidence of recurrent cardiac events in patients prescribed optimal secondary prevention medications and receiving aggressive cardiac risk factor management. METHODS: This was a retrospective study conducted at Kaiser Permanente Colorado and included adults followed by a clinical pharmacy specialist-managed cardiac risk service (CPCRS) with an incident cardiac event and an HbA1c value measured within 1 year prior or 60 days after the incident cardiac event was identified. Cox proportional hazards models were constructed to assess the relationship between HbA1c levels and recurrent cardiac events (assessed as continuous and categorical measures) after adjustment for potential confounding variables. RESULTS: Of 5663 patients identified within an incident cardiac event between January 1999 and March 2005, 1270 (22.4%) patients had a baseline HbA1c value recorded. Of these 1270 patients, 215 (16.9%) had a recurrent cardiac event. Compared with the 'no recurrent event' cohort, the 'recurrent event' cohort were younger, less likely to have undergone an initial coronary artery bypass graft, and more likely to have undergone percutaneous coronary intervention with or without stent. The recurrent event cohort was also less likely to have purchased an HMG-CoA reductase inhibitor ('statin') [p = 0.043] at the time of the incident cardiac event. There was no significant difference in mean baseline HbA1c value between the cohorts. There were also no significant differences between the cohorts when categorized by baseline HbA1c <7% as referent compared with > or =7% to <8%, > or =8% to <9%, > or =9 to <10%, and > or =10%. Moreover, there was no significant difference between cohorts when HbA1c values <7% were compared with values >7% in the unadjusted analysis. Results remained non-significant after adjustment for sex, incident cardiac event type, baseline age, ss-blocker use, statin use and hyperlipidaemia. CONCLUSION: The results of this study suggest that an abnormal HbA1c is not predictive of recurrent cardiac events among patients with cardiovascular disease when other cardiovascular risk factors are being aggressively treated and appropriate secondary prevention medications are being taken. However, larger studies are warranted to validate these findings.

Maintenance of improved lipid levels following attendance at a cardiovascular risk reduction clinic: a 10-year experience.

BACKGROUND: Specialty cardiovascular risk reduction clinics (CRRC) increase the proportion of patients attaining recommended lipid targets; however, it is not known if the benefits are sustained after discharge. We evaluated the impact of a CRRC on lipid levels and assessed the long-term effect of a CRRC in maintaining improved lipid levels following discharge. METHODS: The medical records of consecutive dyslipidemic patients discharged > 6 months from a tertiary hospital CRRC from January 1991 to January 2001 were retrospectively reviewed. The primary outcome was the change in patients' lipid levels between the final CRRC visit and the most recent primary care follow-up. A worst-case analysis was conducted to evaluate the potential impact of the patients in whom the follow-up lipid profiles post-discharge from the CRRC were not obtained. RESULTS: Within the CRRC (median follow-up = 1.28 years in 1064 patients), we observed statistically significant improvements in all lipid parameters. In the 411 patients for whom post-discharge lipid profiles were available (median follow-up = 2.41 years), there were no significant differences observed in low-density lipoprotein-cholesterol, total cholesterol (TC), or triglycerides since CRRC discharge; however, there were small improvements in high-density lipoprotein-cholesterol (HDL-C) and TC:HDL ratio (p < 0.05 for both). The unadjusted worst-case analysis (653 patients with no follow-up lipid profiles) demonstrated statistically significant worsening of all lipid parameters between CRRC discharge and the most recent follow-up. However, when the change in lipid parameters between the baseline and the most recent follow-up was assessed in this analysis, the changes in all lipid parameters were significantly improved (p < 0.05). CONCLUSIONS: This study demonstrates that a CRRC can improve lipid levels and suggests that these benefits are sustained once patients are returned to the care of their primary physician.

Trends in high-intensity statin use and low-density lipoprotein cholesterol control among patients enrolled in a clinical pharmacy cardiac risk service.

BACKGROUND: Although high-intensity statin therapy (HIST) is recommended for most patients between 21 and 75 years of age with atherosclerotic cardiovascular disease (ASCVD), several recent analyses examining contemporary statin use trends have identified a clinical care gap in the utilization of HIST. OBJECTIVE: The objective of this study was to assess secular trends in lipid management for patients with ASCVD enrolled in a clinical pharmacy program within an integrated health care delivery system. METHODS: We performed serial cross-sectional studies over time, comprising 18,006 adults with both acute and chronic ASCVD, to assess trends in statin use and low-density lipoprotein cholesterol (LDL-C) levels from 2007 to 2016. RESULTS: Although the use of statin therapy (any intensity) remained relatively consistent throughout the 10-year study period (89% in 2007, 87% in 2016), the proportion of patients receiving HIST increased over time (44% in 2007, 67% in 2016; P < .001 for trend). Population mean LDL-C levels ranged from 73 to 83 mg/dL with a downward trend over the 10-year study period (P < .001 for trend). By 2016, the proportion of patients attaining an LDL-C <100 mg/dL and <70 mg/dL was 85% and 54%, respectively. Nonstatin lipid-lowering therapy use decreased over the study period, which was primarily driven by decreased use of ezetimibe (24% in 2007, 2% in 2016; P < .001 for trend). CONCLUSIONS: Among adults with ASCVD enrolled in a clinical pharmacy cardiac risk reduction service, guideline-directed use of HIST significantly increased over the past 10 years and coincided with decreased population LDL-C levels.

Mortality reduction benefits of a comprehensive cardiac care program for patients with occlusive coronary artery disease.

STUDY OBJECTIVE: To determine the effect of early and sustained enrollment in a comprehensive cardiac care (CCC) program on all-cause mortality in patients with coronary artery disease (CAD). DESIGN: Retrospective, longitudinal cohort study. DATA SOURCE: Kaiser Permanente Colorado tracking database. PATIENTS: A total of 4896 patients with an incident occlusive CAD event (index event), defined as acute myocardial infarction and/or percutaneous coronary intervention with or without stent placement, between January 1, 1996 and June 30, 2004. MEASUREMENTS AND MAIN RESULTS: All patients were categorized into one of four cohorts by time to enrollment into the CCC program relative to the index event: early CCC-enrolled less than 90 days after the index event (1630 patients), delayed CCC--enrolled 90 days or more after the index event (1211 patients), intermittent CCC--enrolled intermittently with noncontinuous care (483 patients), and no CCC--never enrolled (1572 patients). The primary outcome was all-cause mortality. Patients were censored at death from all causes, end of health plan membership, or study end (December 31, 2005), whichever came first. Patients with any exposure to the CCC were less likely to die compared with the no CCC cohort (p<0.001). After adjusting for baseline covariates, the early, delayed, and intermittent CCC cohorts had reduced hazard rate ratios for all-cause mortality of 0.11 (95% confidence interval [CI] 0.08-0.14), 0.35 (95% CI 0.29-0.44), and 0.54 (95% CI 0.41-0.70), respectively, compared with the no CCC cohort (all p<0.001). CONCLUSIONS: Compared with those not enrolled in the CCC program, patients enrolled in the early CCC were 89% less likely to die. The earlier the program is started after a coronary event, the better the mortality reduction benefit.

Factors related to adherence to statin therapy.

BACKGROUND: Retrospective database analyses have revealed that 50% of patients receiving statins discontinue therapy after one year of treatment. Typically, these data do not focus on patient-specific reasons for discontinuation. OBJECTIVE: To examine the reasons that patients discontinue statins and compare the patient and clinical factors of those who do and do not discontinue therapy. METHODS: All patients with a new statin prescription between January 1, 2004, and March 31, 2004, were identified through pharmacy claims. Patients who had discontinued and continued statin therapy were identified. Medical records were reviewed to determine whether there were documented reasons for statin discontinuation. Subsequently, telephone surveys addressing statin knowledge, relationships, communication with healthcare providers, and general health status were conducted. RESULTS: At one year, 47.5% (n = 671) of patients had obtained fewer than 80% of the refills of their prescribed statin. We reviewed 435 medical records and conducted 255 patient surveys. A total of 29.9% of discontinuers had reasons documented in the medical record. Compared with continuers, fewer discontinuers had follow-up and/or laboratory visits with a provider within 6 months after the start of statin therapy. The surveys indicated that more continuers than discontinuers trusted their providers (p < 0.05) and felt that providers had adequate knowledge to answer their questions (p < 0.001). In contrast, more discontinuers felt the statin was of limited benefit/unsure of the benefit (p < 0.001) and believed that their providers were not interested in their input on their medical condition (p < 0.01). CONCLUSIONS: Utilizing pharmacy claims records alone to determine statin nonadherence may not only overestimate the percentage of patients who are nonadherent, but also prevent healthcare providers from understanding the reasons that patients discontinue or continue statin therapy. Statin adherence is complex and affected by several factors. Interventions to improve adherence should focus on patient communications, education, and follow-up.

Clinical pharmacy cardiac risk service for managing patients with coronary artery disease in a health maintenance organization.

PURPOSE: A clinical pharmacy service for managing the treatment of coronary artery disease in a health maintenance organization is described. SUMMARY: Despite the proven benefits of aggressive risk factor modification for patients with coronary artery disease (CAD), there remains a treatment gap between consensus- and evidence-based recommendations and their application in patient care. In 1998, Kaiser Permanente of Colorado developed the Clinical Pharmacy Cardiac Risk Service (CPCRS) to focus on the long-term management of patients with CAD to improve clinical outcomes. The primary goals of the CPCRS are to increase the number of CAD patients on lipid-lowering therapy, manage medications shown to decrease the risk of future CAD-related events, assist in the monitoring and control of other diseases that increase cardiovascular risk, provide patient education and recommendations for nonpharmacologic therapy, and act as a CAD information resource for physicians and other health care providers. Using an electronic medical record and tracking database, the service works in close collaboration with primary care physicians, cardiologists, cardiac rehabilitation nurses, and other health care providers to reduce cardiac risk in the CAD population. Particular attention is given to dyslipidemia, blood pressure, diabetes mellitus, and tobacco cessation. Treatment with evidence-based regimens is initiated and adjusted as necessary. Over 11,000 patients are currently being followed by the CPCRS. CONCLUSION: A clinical pharmacy service in a large health maintenance organization provides cardiac risk reduction for patients with CAD and helps close treatment gaps that may exist for these patients.

Complementary and alternative therapies for the management of dyslipidemia.

OBJECTIVE: To review the literature on select alternative therapies for the management of dyslipidemia. DATA SOURCES: Searches of MEDLINE and PubMed (1965-March 2006) were conducted using the key terms omega-3-fatty acids, policosanol, plant stanols and sterols, flaxseed, red yeast rice, guggulipid, garlic, fiber, almonds, and cholesterol and/or lipids. STUDY SELECTION AND DATA EXTRACTION: Meta-analyses, published in English and involving adults, that incorporated randomized, controlled trials on alternative therapies for dyslipidemia were reviewed. Additionally, trials published subsequent to the meta-analyses were reviewed. Articles deemed relevant were included in this review. DATA SYNTHESIS: Of the aforementioned alternative therapies, randomized controlled trials were found for omega-3-fatty acids, policosanol, plant stanols and sterols, flaxseed, red yeast rice, guggulipid, garlic, fiber, almonds, and soy. Studies for each of these agents report varying degrees of lipid reduction. Based on published data, effective therapeutic options for lipid-lowering include intake of fiber, intake of plant stanols/sterols, replacement of animal protein with soy protein, and substitution of foods high in saturated fat with those with monounsaturated fatty acids (eg, dry roasted almonds). Adding omega-3-fatty acids is effective for reducing triglycerides in patients with hypertriglyceridemia. Well-designed studies with long-term outcome data are necessary to further define the role for guggul, red yeast rice, policosanol, garlic, and flaxseed in the management of dyslipidemia. CONCLUSIONS: Alternative therapeutic approaches with complementary therapies are becoming increasingly popular among patients. It is important for healthcare providers to be familiar with the safety and efficacy of these agents to facilitate optimal outcomes for patients with dyslipidemia.

Lipid management in patients with coronary artery disease by a clinical pharmacy service in a group model health maintenance organization.

BACKGROUND: Published data indicate that there is a significant treatment gap between the evidence for and the implementation of lipid-lowering therapy and that recidivism is as high as 60% at 1 year. The aim of this study is to examine the impact of a clinical pharmacy cardiac risk service (CPCRS) on lipid screening, control, and treatment outcomes. METHODS: A computer-generated list of all patients with documented coronary artery disease, enrolled in a CPCRS between March 1, 1998, and October 1, 2002, and followed up for a minimum of 6 months was obtained. Outcome measures were the percentage of patients with up-to-date lipid screening results and the percentage achieving low-density lipoprotein cholesterol (LDL-C) goals at enrollment in CPCRS and at study end. RESULTS: A total of 8014 patients (mean age, 69.3 years; 69.8% men) met the entry criteria. The mean duration of follow-up was 2.3 years. Most patients (97.3%) had up-to-date lipid screening results at study end compared with 66.9% of patients at baseline. At study end, a total of 72.9% of patients achieved a LDL-C level of less than 100 mg/dL (<2.6 mmol/L) compared with 25.5% at baseline. The mean +/- SD LDL-C level for the cohort at study end was 89 +/- 24 mg/dL (2.3 +/- 0.6 mmol/L). Of patients receiving medication, most (84.8%) were receiving therapy with statins alone, whereas 11.7% were receiving combination therapy. CONCLUSIONS: A CPCRS working in conjunction with a patient-tracking system can achieve improved lipid results in a large and inclusive cohort of patients with coronary artery disease. Our approach is unique in that the results were sustainable and demonstrate reduced recidivism.
