Effect of a clinical pharmacist-managed lipid clinic on achieving National Cholesterol Education Program low-density lipoprotein goals

Value of the clinical pharmacist interventions in the application of the American College of Cardiology (ACC/AHA) 2018 guideline for cholesterol management

OBJECTIVES

The study aims to examine the extent to which the updated ACC/AHA management of blood cholesterol guideline (2018) is implemented in practice and to assess the value of the clinical pharmacist interventions in improving physicians' adherence the guidelines recommendations.

METHODS

We utilized in this study an interventional before-after design. The study was conducted on 272 adult patients who visited the study site internal medicine clinics and were candidates for statin therapy based on the 2018 ACC/AHA guidelines for cholesterol management. Adherence to guideline recommendations was measured before and after clinical pharmacists' interventions by calculating the percentage of patients receiving statin therapy as per guideline recommendation, the type and intensity (moderate or high intensity) of statin therapy used, and the need for additional non-statin therapy.

RESULTS

Adherence with guideline recommendations was significantly improved from 60.3% to 92.6% (X2 = 79.1, p = 0.0001) after clinical pharmacist interventions. Among patients who were on statin therapy, the percentage of those who were on proper statin intensity increased significantly from 47.6% to 94.4% (X2 = 72.5, p = 0.0001). The combination of statins with non-statin therapies such as ezetimibe and PCSK9 inhibitors increased from 8.5% to 30.6% (X2 = 95, p<0.0001) and from 0.0% to 1.6% (X2 = 6, p = 0.014), respectively. The use of other lipid-lowering agents was diminished from 14.6% to 3.2% (X2 = 19.2, p<0.0001).

CONCLUSION

Collaboration between physicians and clinical pharmacists is a crucial strategy to improve patients' treatment and hence, achieve better health outcomes among patients suffering from dyslipidemia.

The Role of Clinical Pharmacist in Pediatrics' Adherence to Antiepileptic Drugs

Background

Rate of nonadherence to antiepileptic drugs (AEDs) in children is about 33%. Engaging clinical pharmacists in the management of patients has proved to increase adherence to medications which will improve the outcomes of treatment.

Objectives

To investigate the effect of a clinical pharmacist-led education on the adherence to AEDs in pediatric patients with epilepsy. Secondary outcomes include effectiveness and safety of AEDs, satisfaction with information about AEDs provided to the caregivers, and patients quality of life (QoL).

Methods

This was an interventional study where pediatric patients were randomly assigned to the intervention (n = 41) or the control (n = 40) group. A 30-minute clinical pharmacist-led educational interview to the parent/caregiver was provided to the first group as add-on to standard medical care received by latter. Outcomes were measured at baseline and after 8-week follow-up.

Results

The intervention group had an increase in mean adherence score from 6 ± 1.09 at baseline to 7.6 ± 0.9 at follow-up (P value < 0.001), while the control group had no significant change (P value > 0.05), the difference between the 2 groups at follow-up was significant (P value < 0.0001). No significant difference was observed between groups at follow-up with regard to effectiveness (P value > 0.05), and safety (P value = 0.08). While higher satisfaction with information (P value < 0.0001), and higher QoL (P value < 0.05) was observed in the intervention group.

Conclusion and relevance

Clinical pharmacist-led education had a positive outcome on pediatric patients with epilepsy with regard to adherence, effectiveness, safety, satisfaction with information about AEDs, and QoL.

The "Warrior" system: a new useful emergency simulator to train clinical pharmacists in emergency medicine

Clinical pharmacists are indispensable providers of emergency medical services. However, the training of Chinese clinical pharmacists in medical emergency skills is apparently insufficient.The current study aimed to evaluate the effect of the "Warrior" emergency simulator application in the emergency medical education of clinical pharmacy students (CP students).The "Warrior" system, which contains a pharmacokinetics/pharmacodynamics-linked model and a drug database, was successfully employed to train CP students and improve their capability to deal with various medical emergency situations. Both an objective (in-class) test and the subjective Dundee Ready Education Environment Measure (DREEM) were administered to 20 CP students, randomly divided into an intervention group and a control group, to estimate the teaching effect of the "Warrior" system.The scores of CP students from the intervention group were significantly higher (P < .01) in the in-class test than the scores of students from the control group due to the diverse situational teaching using the "Warrior" system. The results of the DREEM showed that CP students from the intervention group obtained considerably better (P < .01) marks for "students' perceptions of learning" and "students' perceptions of atmosphere" than those from the control group. Furthermore, the intervention group scored much higher (P < .01) than the control group on the total DREEM.The "Warrior" system provides an excellent training path for clinical pharmacists that supplies a more realistic clinical simulation experience and significantly improves the teaching effect. The "Warrior" system exhibits high potential for future development in emergency medical education.

Implementation and Assessment of a Pharmacy Educational Program Concerning Laboratory Monitoring for Medications

BACKGROUND

The pharmacist's role in monitoring medication therapy, including the ability to order laboratory tests as a delegated medical function, has increased dramatically over the past 20 years.

OBJECTIVES

To implement and assess the impact of an intervention designed to educate pharmacists about appropriate medication-related laboratory monitoring and clinical interpretation of results.

METHODS

This pilot project had a pretest-posttest study design. The intervention was an educational program comprising 8 self-directed learning modules, each with a corresponding seminar. Evaluation of the program included scoring of the appropriateness and significance of clinical interventions related to laboratory monitoring, pre- and post-program test scores, and participants' subjective assessments of their abilities to order and assess the results of medication-related laboratory investigations. Descriptive statistics, the Wilcoxon signed rank test, the Student t-test, and the paired Student t-test were used where appropriate. Associations were assessed with the Pearson or Spearman rho correlation coefficient. All statistical tests were 2-tailed, and the p value for significance was established a priori at 0.05.

RESULTS

There was no statistically significant difference with regard to the appropriateness (p = 0.70) or significance (p = 0.94) of clinical interventions undertaken before and after the educational program. Among the 21 pharmacists who completed the program, the average test score (± standard deviation) was 27.2 ± 8.1 before the program, increasing to 39.2 ± 8.7 after the program (p < 0.001). There was a statistically significant improvement in the perceived level of knowledge for each individual module (p < 0.05 for all).

CONCLUSIONS

The establishment of an educational program led to improvements in both subjective and objective measures of knowledge and perceived abilities to order and assess the results of medication-related laboratory tests.

Pharmacist Critique Was Ill-Informed

Pharmacists’ ability to exercise “professional right of conscience” in dispensing emergency contraception, as well as the professionalism of pharmacists, has fallen under attack recently by the media, by state governments, and even by other healthcare professionals in published commentaries. This editorial discusses the controversy surrounding emergency contraceptives, the right of pharmacists to refuse to fill prescriptions that they consider morally objectionable, and the responsibility of pharmacists to provide medications in a timely and professional manner. The professionalism of pharmacy is also examined in light of the expanded scope of practice in which pharmacists increasingly find themselves practicing.

Clinical and economic consequences of statin intolerance in the United States: Results from an integrated health system

BACKGROUND

Although statins are considered safe and effective, they have been associated with statin intolerance (SI) in clinical and observational studies.

OBJECTIVE

The objective of this study was to describe the clinical and economic consequences of SI through comparison of an SI cohort of patients with matched controls.

METHODS

This study used data extracted from an integrated health system's electronic health records from 2008 to 2014. Adults with SI were matched to controls using a propensity score. Patients were hierarchically classified into 6 mutually exclusive cardiovascular (CV)-risk categories: recent acute coronary syndrome (ACS; ≤12 months preindex), coronary heart disease, ischemic stroke, peripheral artery disease, diabetes, or primary prevention. The study endpoints, low-density lipoprotein cholesterol (LDL-C) goal attainment, medical costs, and time to first CV event were compared using conditional logistic regression, generalized linear, and Cox proportional hazards models, respectively.

RESULTS

Patients with SI (n = 5190) were matched with controls (n = 15,570). Patients with SI incurred higher medical costs and were less likely to reach LDL-C goals than controls. Patients with SI were at higher risk for revascularization procedures in all CV risk categories except ACS, and those in the diabetes risk category were at higher risk for any CV event. There was a lower risk of all-cause death among patients with SI.

CONCLUSIONS

Patients with SI were less likely to reach LDL-C goals, incurred higher health care costs, and experienced a higher risk for nonfatal CV events than patients without SI. Alternative management strategies are needed to better treat high CV risk patients.

Pharmacist Intervention in Risk Reduction Study: High-Risk Cardiac Patients

Objectives:

Although there are guidelines for managing patients at high vascular risk, many people remain undertreated. This community-based study was designed to 1) measure the ability of the pharmacist—physician collaboration to affect a broad array of drug-related endpoints and 2) to compare 2 methods of training community pharmacists to collaborate with physicians on cardiac patient care. This paper focuses on the first outcome, and a companion paper will address the second outcome.

Methods:

We used a before-and-after design to assess pharmacists' ability to affect drug-related endpoints. We identified patients by various methods, one of which was medication profiles. Those providing consent were educated on risk factor modification and encouraged to consult their physicians. Pharmacists subsequently faxed the details of their assessments to the primary care physician, along with suggestions for therapy changes. Our outcome measure was the proportion of patients who achieved a composite of either a dose increase or a new target medication as a result of pharmacist recommendations during the study.

Results:

A total of 61 pharmacists recruited 217 patients, and of these, follow-up was completed on 216. Of the patients for whom a pharmacist made a suggestion, pharmacologic risk reduction therapy was initiated or enhanced in 53.7%.

Conclusion:

This community pharmacist—based program improved utilization of the therapies known to decrease vascular risk in patients considered high risk.

Role of the Pharmacist in the Management of Dyslipidemia

Dyslipidemia is one of a number of independent risk factors for cardiovascular disease. Numerous large-scale, randomized clinical trials demonstrate the benefit of aggressive lipid-modifying therapy in reducing the mortality and morbidity associated with cardiovascular disease. Despite these data and the wide dissemination of clinical practice guidelines outlining management strategies for patients with dyslipidemia, particularly those at the greatest cardiovascular risk, studies indicate that a significant proportion of patients are not screened, initiated on appropriate therapy, or treated to target lipid levels. Pharmacists, as part of the multidisciplinary team, can play a vital role in assisting in the management of patients with dyslipidemias. This article reviews published studies that have evaluated the pharmacist's role in lipid management, reviews the process for managing a patient with dyslipidemia, and provides suggestions on how pharmacists can become more involved in lipid management.

Pharmacist-managed clinics for patient education and counseling in Japan: current status and future perspectives

To improve the adherence to and knowledge about pharmacotherapy in outpatients and to maximize the efficacy and minimize the adverse drug events, the first pharmacist-managed clinic (PMC) in Japan was established for anticoagulation therapy at Nagoya University Hospital in 2000. Since then, various PMCs such as for asthma/chronic obstructive pulmonary disease, Alzheimer's disease, hypercholesterolemia, chronic hepatitis C, cancer chemotherapy, palliative care, chronic kidney disease, and continuous ambulatory peritoneal dialysis have been established and expanded to many hospitals in Japan. Accumulating evidences suggest that PMCs have some beneficial effects on patients' adherence to and knowledge about their pharmacotherapy as well as the clinical outcome, besides being cost-effective. Notably, PMCs for cancer chemotherapy have been approved as a new medical service in hospitals in 2014, which is covered by the universal health coverage in Japan. In this review article, the current status of PMCs for patient education and counseling in Japan and their impact on pharmaceutical care and management are critically reviewed. Furthermore, future perspectives on PMCs are discussed.

A comprehensive analysis of dyslipidaemia management in a large health care system

RATIONALE, AIMS AND OBJECTIVES

Dyslipidaemia is a cardiovascular risk factor, and national screening and treatment guidelines have been established, but achievement of these remains inadequate. Multidisciplinary approaches, such as the chronic care model, have been applied to other chronic diseases and likely would be applicable to the management of dyslipidaemia. We therefore aimed to comprehensively study the different components of a multidisciplinary management approach to dyslipidaemia in a large health care system for patients at a high risk for cardiovascular events.

METHODS

All patients at a Veterans Affairs Medical Center in the United States over 3 years with diabetes and/or coronary artery disease were included. Various clinical and demographic variables were collected and achievement of national cholesterol goals was determined. Univariate and multivariate analyses were conducted to determine the association of different health care variables with improved patient cholesterol guideline achievement.

RESULTS

There were 3559 patients in the study population and 51.0% had achieved national cholesterol goals. Multivariate analyses showed that patients who had achieved goals were more likely to have attended cardiology clinic [odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.3-2.01] and nutrition clinic (OR = 1.3, 95% CI = 1.04-1.7) and were more likely to have primary care providers who were nurse practitioners (OR = 1.6, 95% CI = 1.2-2.0), practicing full-time (OR = 1.8, 95% CI = 1.5-2.1) and at the main hospital-based clinics (OR = 1.5, 95% CI = 1.3-1.9).

CONCLUSIONS

Our study identifies different components of a multidisciplinary approach to management of dyslipidaemia that are efficacious and these results may help guide future investment in this area.

Hospital pharmacy practice in Saudi Arabia: Drug monitoring and patient education in the Riyadh region

BACKGROUND

The purpose of this national survey is to evaluate hospital pharmacy practice in the Riyadh region of Saudi Arabia. The results of the survey pertaining to the monitoring and patient education of the medication use process were presented.

METHODS

We have invited pharmacy directors from all 48 hospitals in the Riyadh region to participate in a modified-American Society of Health-System Pharmacists (ASHP) survey questionnaire. The survey was conducted using similar methods to those of the ASHP surveys.

RESULTS

The response rate was 60.4% (29/48). Most hospitals (23, 79%) had pharmacists regularly monitor medication therapy for patients. Of these hospitals, 61% had pharmacists monitoring medication therapy daily for less than 26% of patients, 17% monitored 26-50% of patients and 22% monitored more than half of patients daily. In 41% of hospitals, pharmacists routinely monitored serum medication concentrations or their surrogate markers; 27% gave pharmacists the authority to order initial serum medication concentrations, and 40% allowed pharmacists to adjust dosages. Pharmacists routinely documented their medication therapy monitoring activities in 52% of hospitals. Overall, 74% of hospitals had an adverse drug event (ADE) reporting system, 59% had a multidisciplinary committee responsible for reviewing ADEs, and 63% had a medication safety committee. Complete electronic medical record (EMR) systems were available in 15% of hospitals and 81% had a partial EMR system. The primary responsibility for performing patient medication education lays with nursing (37%), pharmacy (37%), or was a shared responsibility (26%). In 44% of hospitals, pharmacists provided medication education to half or more inpatients and in a third of hospitals, pharmacists gave medication education to 26% or more of patients at discharge.

CONCLUSION

Hospital pharmacists in the Riyadh region are actively engaged in monitoring medication therapy and providing patient medication education, although there is considerable opportunity for further involvement.

Benefits of Individualized Counseling by the Pharmacist on the Treatment Outcomes of Hyperlipidemia in Hong Kong

A prospective controlled study on the benefits of pharmacists' individualized counseling on drug compliance, cholesterol concentration reduction, attainment of National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) low-density lipoprotein cholesterol (LDL-C) goals, and patient satisfaction was carried out in a private community hospital in Hong Kong. All patients who were newly prescribed with lipid-lowering drugs for primary prevention were included. The patients in the individualized counseling group received "intense" counseling and follow-up of cholesterol concentration by a pharmacist for 3 months. The control group received routine counseling. Fifty patients completed the study (26 in the individualized group, 24 in the control group). Compliance was assessed, and those patients who achieved 75% compliance were defined as compliers. In the individualized group, 76.9% were compliers compared with 41.7% in the control group (p < 0.01). The individualized group achieved 28.3%, 27.7%, and 26.1% reduction in total cholesterol, LDL-C, and triglycerides, respectively, compared with 15.3%, 16.3%, and 10.6% in the control group (p < 0.05 for all). Also in the individualized group, 80.8% achieved the ATP III LDL-C goals compared to 58.3% in the control group (p < 0.05). Of patients in the individualized group, 85% felt that the pharmacist counseling service could improve their disease management. The study demonstrated that pharmacists' individualized counseling, together with the assessment of cholesterol concentrations, had positive impacts on the management of hyperlipidemia, including improved drug compliance, better treatment endpoints, and patient satisfaction.

The Role of Team-Based Care Involving Pharmacists to Improve Cardiovascular and Renal Outcomes

The number of patients with cardiovascular and kidney disease in the United States continues to grow as the population ages, increasing the demand on the health care system and its providers. Many patients develop chronic conditions in which optimization of care is labor intensive, specifically hypertension, hyperlipidemia, diabetes, heart failure, and chronic kidney disease. Therefore, innovative and collaborative approaches to health care are warranted. Several team-based health care models have evolved and are gaining popularity, including the Patient-Centered Medical Home (PCMH) and Medication Therapy Management (MTM). Team-based care is widely supported in the literature, demonstrating significant improvement in cardiovascular and renal outcomes. This article will review the premises of PCMH and MTM, review the evidence and roles for team-based care specific to cardiovascular and renal outcomes, and introduce fundamentals to implement collaborative practice focusing on pharmacist-provider teams.

Pilot study of a pharmaceutical care intervention in an outpatient lung transplant clinic

BACKGROUND

Lung transplant recipients have complex drug regimens. Study objectives were to assess drug therapy problems (DTPs), pharmacist recommendations, and patient satisfaction with pharmacist services.

METHODS

Using a pharmaceutical care assessment process, pharmacists identified DTPs and made therapeutic recommendations. Number of DTPs identified per pharmacist visit was calculated and compared to standard care visits through retrospective chart review. Potential clinical impact of recommendations was evaluated by blinded clinicians. Patient satisfaction was assessed via survey.

RESULTS

Fifty-five DTPs were identified in 43 patients over 50 pharmacist visits (1.05 ± 1.34 DTPs per visit). In these same patients, rate of DTP identification was 0.51 ± 0.64 DTPs per standard visit in the preceding two-wk period (p = 0.018 vs. pharmacist visit). The most common DTPs identified by the pharmacist were adverse drug effect (27%) and untreated indication (25%). Overall, 62% of pharmacist recommendations were rated very significant or significant. Survey return rate was 58% and satisfaction scores ranged from 3 to 5 out of 5. Review of medications and teaching regarding the use of medications received the most "very satisfied" and "highly important" scores.

CONCLUSIONS

Pharmacists can make valuable contributions in a lung transplant clinic setting by identifying DTPs and making recommendations with a positive impact on patient outcomes and satisfaction.

Patient Perceptions of Pharmacist-Managed Clinics: A Qualitative Analysis

Background:

Pharmacist-managed clinics have consistently demonstrated improvement in patient outcomes. Quantitative research offers the benefit of objective outcomes to track progress toward therapeutic goals at pharmacist-managed clinics. While quantitative studies are readily available in the literature, there is a paucity of qualitative studies to capture the patients' perspectives of pharmacy services.

Objective:

To assess through the use of qualitative research methods patient perceptions of pharmacist-managed services within ambulatory care clinics that operate under a collaborative practice agreement.

Methods:

A semi-structured interview questionnaire was developed, pilot tested, and revised using a focus group of clinical pharmacists. The questionnaire was used to conduct face-to-face patient interviews at 6 pharmacist-managed clinics in central Indiana. English-speaking patients with a minimum of 2 visits with the clinical pharmacist were included in this study. Pharmacist-managed clinics without established collaborative practice agreements were excluded. Patient interviews were conducted by a trained research assistant, audio-recorded, and transcribed verbatim. The interview transcripts were analyzed to identify cross-cutting themes without predetermined definitions via inductive qualitative analysis. Four study investigators independently identified themes using a sample of the transcripts. Additional themes were identified and defined in a series of independent reviews and investigator meetings using the remaining transcripts until theme saturation. All themes were assigned to segments of the interview transcripts according to the consensus definitions.

Results:

A total of 30 interviews were conducted across the clinics. Ten themes from the interview transcripts emerged, including disease state management expertise, patient alliance, practice novelty, accessibility, increased sense of patient well-being, and compassion.

Conclusions:

Patient perceptions from qualitative interviews revealed that pharmacists are viewed as medication experts who provide patient-centered care. This study highlights unique in-depth perspectives from the patient that further support maintenance and expansion of pharmacist-managed services.

A pharmaceutical care program to improve adherence to statin therapy: a randomized controlled trial

BACKGROUND

Despite the well-known beneficial effects of statins, many patients do not adhere to chronic medication regimens.

OBJECTIVE

To implement and assess the effectiveness of a community pharmacy-based pharmaceutical care program developed to improve patients' adherence to statin therapy.

METHODS

An open-label, prospective, randomized controlled trial was conducted at 26 community pharmacies in the Netherlands. New users of statins who were aged 18 years or older were randomly assigned to receive either usual care or a pharmacist intervention. The intervention consisted of 5 individual counseling sessions by a pharmacist during a 1-year period. During these sessions, patients received structured education about the importance of medication adherence, lipid levels were measured, and the association between adherence and lipid levels was discussed. Adherence to statin therapy was assessed as discontinuation rates 6 and 12 months after statin initiation, and as the medication possession ratio (MPR), and compared between the pharmaceutical care and usual care groups.

RESULTS

A total of 899 subjects (439 in the pharmaceutical care group and 460 in the usual care group) were evaluable for effectiveness analysis. The pharmaceutical care program resulted in a significantly lower rate of discontinuation within 6 months after initiating therapy versus usual care (HR 0.66, 95% CI 0.46 to 0.96). No significant difference between groups was found in discontinuation at 12 months (HR 0.84, 95% CI 0.65 to 1.10). Median MPR was very high (>99%) in both groups and did not differ between groups.

CONCLUSIONS

These results demonstrate the feasibility and effectiveness of a community pharmacy-based pharmaceutical care program to improve medication adherence in new users of statins. Frequent counseling sessions (every 3 months) are necessary to maintain the positive effects on discontinuation. Although improvements are modest, the program can be applied easily to a larger population and have a large impact, as the interventions are relatively inexpensive and easy to implement in clinical practice.

Clinical and Economic Impact of Clinical Pharmacy Service on Hyperlipidemic Management in Hong Kong

Objective: To assess the clinical and economic outcomes of a clinical pharmacy service (CPS) in dyslipidemic management. Method: This was a 24-month prospective controlled trial conducted at the lipid clinic of a public hospital in Hong Kong. In the intervention group, a clinical pharmacist assessed low-density lipoprotein cholesterol (LDL-C) levels and provided recommendations in accordance to the Adult Treatment Panel III (ATP III) guidelines. Medication compliance and the proper use of drugs were assessed. Education on healthy lifestyles was reinforced. Monthly telephone follow-ups were made to check on the progress of patients. In the control group, patients received usual medical care with no pharmacist intervention. Primary outcome was the percentage of patients achieving the ATP III LDL-C goal at the end of study. The estimated cost of such service was also evaluated. Results: A total of 300 patients were recruited into the study (150 in intervention group and 150 in control group). In the intervention group, 58.7% patients achieved LDL-C goals compared with 45.3% in the control group (P < .05). The intervention group achieved 26.4%, 17.4%, and 30.0% mean reduction in LDL-C, total cholesterol (TC), and triglycerides (TG) levels, respectively, compared with 12.6%, 6.6%, and 11.5% in the control group (P < .05). The estimated cost for this clinical service was US$385/month for a total of 600 dyslipidemic patients seen per year. Conclusion: The results of this study demonstrate the positive impact CPS can have on achieving treatment goals in lipid management. Similar services for other problematic conditions such as hypertension and diabetes mellitus may also be benefited by similar CPSs.

Comparison of a pharmacist-managed lipid clinic: in-person versus telephone

OBJECTIVE

To compare the effectiveness of an in-person versus telephone-based pharmacist-managed lipid clinic.

METHODS

Retrospective examination of a pharmacist-managed lipid clinic conducted at a Veterans Affairs medical center between September 2005 and March 2008. The clinical pharmacist educated, monitored, recommended nonpharmacologic treatment, and prescribed lipid-lowering medications using an in-person or telephone-based clinic style. The primary outcomes were to compare the two clinic styles on the percent of patients who reached their low-density lipoprotein (LDL) cholesterol goal and the absolute percent of LDL cholesterol reduction.

RESULTS

157 patients with coronary artery disease or its risk equivalent were enrolled in the pharmacist-managed lipid clinic. Overall, patients experienced a mean 27% reduction in LDL cholesterol levels from baseline, and 76% reached their LDL cholesterol goal. No significant differences in the percent of patients reaching their LDL cholesterol goal or absolute percent reduction in LDL cholesterol levels were found between the in-person and phone-based clinics. A trend toward phone clinic patients achieving their goal LDL cholesterol levels more quickly was noted.

CONCLUSION

Both in-person and phone-based pharmacist-managed lipid clinics offer effective methods to improve the cholesterol levels of patients. Phone-based clinics may offer more advantages in efficiency for pharmacists and their patients and the potential to deliver care in a wider variety of pharmacy settings.

Effect of outpatient pharmacists' non-dispensing roles on patient outcomes and prescribing patterns

BACKGROUND

The roles of pharmacists in patient care have expanded from the traditional tasks of dispensing medications and providing basic medication counseling to working with other health professionals and the public. Multiple reviews have evaluated the impact of pharmacist-provided patient care on health-related outcomes. Prior reviews have primarily focused on in-patient settings. This systematic review focuses on services provided by outpatient pharmacists in community or ambulatory care settings. This is an update of the Cochrane review published in 2000.

OBJECTIVES

To examine the effect of outpatient pharmacists' non-dispensing roles on patient and health professional outcomes.

SEARCH STRATEGY

This review has been split into two phases. For Phase I, we searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (January 1966 through March 2007). For Phase II, we searched MEDLINE/EMBASE (January 1966 through March 2008). The Phase I results are reported in this review; Phase II will be summarized in the next update.

SELECTION CRITERIA

Randomized controlled trials comparing 1. Pharmacist services targeted at patients versus services delivered by other health professionals; 2. Pharmacist services targeted at patients versus the delivery of no comparable service; 3. Pharmacist services targeted at health professionals versus services delivered by other health professionals; 4. Pharmacist services targeted at health professionals versus the delivery of no comparable service.

DATA COLLECTION AND ANALYSIS

Two authors independently reviewed studies for inclusion, extracted data, and assessed risk of bias of included studies.

MAIN RESULTS

Forty-three studies were included; 36 studies were pharmacist interventions targeting patients and seven studies were pharmacist interventions targeting health professionals. For comparison 1, the only included study showed a significant improvement in systolic blood pressure for patients receiving medication management from a pharmacist compared to usual care from a physician. For comparison 2, in the five studies evaluating process of care outcomes, pharmacist services reduced the incidence of therapeutic duplication and decreased the total number of medications prescribed. Twenty-nine of 36 studies reported clinical and humanistic outcomes. Pharmacist interventions resulted in improvement in most clinical outcomes, although these improvements were not always statistically significant. Eight studies reported patient quality of life outcomes; three studies showed improvement in at least three subdomains. For comparison 3, no studies were identified meeting the inclusion criteria. For comparison 4, two of seven studies demonstrated a clear statistically significant improvement in prescribing patterns.

AUTHORS' CONCLUSIONS

Only one included study compared pharmacist services with other health professional services, hence we are unable to draw conclusions regarding comparisons 1 and 3. Most included studies supported the role of pharmacists in medication/therapeutic management, patient counseling, and providing health professional education with the goal of improving patient process of care and clinical outcomes, and of educational outreach visits on physician prescribing patterns. There was great heterogeneity in the types of outcomes measured across all studies. Therefore a standardized approach to measure and report clinical, humanistic, and process outcomes for future randomized controlled studies evaluating the impact of outpatient pharmacists is needed. Heterogeneity in study comparison groups, outcomes, and measures makes it challenging to make generalised statements regarding the impact of pharmacists in specific settings, disease states, and patient populations.

The preventing recurrent vascular events and neurological worsening through intensive organized case-management (PREVENTION) trial protocol [clinicaltrials.gov identifier: NCT00931788]

Background

Survivors of transient ischemic attack (TIA) or stroke are at high risk for recurrent vascular events and aggressive treatment of vascular risk factors can reduce this risk. However, vascular risk factors, especially hypertension and high cholesterol, are not managed optimally even in those patients seen in specialized clinics. This gap between the evidence for secondary prevention of stroke and the clinical reality leads to suboptimal patient outcomes. In this study, we will be testing a pharmacist case manager for delivery of stroke prevention services. We hypothesize this new structure will improve processes of care which in turn should lead to improved outcomes.

Methods

We will conduct a prospective, randomized, controlled open-label with blinded ascertainment of outcomes (PROBE) trial. Treatment allocation will be concealed from the study personnel, and all outcomes will be collected in an independent and blinded manner by observers who have not been involved in the patient's clinical care or trial participation and who are masked to baseline measurements. Patients will be randomized to control or a pharmacist case manager treating vascular risk factors to guideline-recommended target levels. Eligible patients will include all adult patients seen at stroke prevention clinics in Edmonton, Alberta after an ischemic stroke or TIA who have uncontrolled hypertension (defined as systolic blood pressure (BP) > 140 mm Hg) or dyslipidemia (fasting LDL-cholesterol > 2.00 mmol/L) and who are not cognitively impaired or institutionalized. The primary outcome will be the proportion of subjects who attain 'optimal BP and lipid control'(defined as systolic BP < 140 mm Hg and fasting LDL cholesterol < 2.0 mmol/L) at six months compared to baseline; 12-month data will also be collected for analyses of sustainability of any effects. A variety of secondary outcomes related to vascular risk and health-related quality of life will also be collected.

Conclusions

Nearly one-quarter of those who survive a TIA or minor stroke suffer another vascular event within a year. If our intervention improves the provision of secondary prevention therapies in these patients, the clinical (and financial) implications will be enormous.

Interventions to improve adherence to lipid lowering medication

BACKGROUND

Lipid lowering drugs are still widely underused, despite compelling evidence about their effectiveness in the treatment and prevention of cardiovascular disease. Poor patient adherence to a medication regimen is a major factor in the lack of success in treating hyperlipidaemia. In this updated review we focus on interventions which encourage patients at risk of heart disease or stroke to take lipid lowering medication regularly.

OBJECTIVES

To assess the effects of interventions aimed at improved adherence to lipid lowering drugs, focusing on measures of adherence and clinical outcomes.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 1), MEDLINE, EMBASE, PsycINFO and CINAHL (March 2008). No language restrictions were applied.

SELECTION CRITERIA

Randomised controlled trials of adherence-enhancing interventions for lipid lowering medication in adults for both primary and secondary prevention of cardiovascular disease in an ambulatory setting looking at adherence, serum lipid levels, adverse effects and health outcomes. Studies were selected independently by two review authors.

DATA COLLECTION AND ANALYSIS

Data were extracted and assessed by two review authors following criteria outlined by the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

Three additional studies were found in the update and, in total, 11 studies were included in this review. The studies included interventions that caused a change in adherence ranging from -3% to 25% (decrease in adherence by 3% to increase in adherence by 25%). Patient re-enforcement and reminding was the most promising category of interventions, investigated in six trials of which four showed improved adherent behaviour of statistical significance (absolute increase: 24%, 9%, 8% and 6%). Other interventions associated with increased adherence were simplification of the drug regimen (absolute increase 11%) and patient information and education (absolute increase 13%). The methodological and analytical quality of some studies was low and results have to be considered with caution.

AUTHORS' CONCLUSIONS

At this stage, reminding patients seems the most promising intervention to increase adherence to lipid lowering drugs. The lack of a gold standard method of measuring adherence is one major barrier in adherence research. More reliable data might be achieved by newer methods of measurement, more consistency in adherence assessment and longer duration of follow up. More recent studies have started using more reliable methods for data collection but follow-up periods remain too short. Increased patient-centredness with emphasis on the patient's perspective and shared decision-making might lead to more conclusive answers when searching for tools to encourage patients to take lipid lowering medication.

Adherence: a review of education, research, practice, and policy in the United States

Objective

To describe the education, research, practice, and policy related to pharmacist interventions to improve medication adherence in community settings in the United States.

Methods

Authors used MEDLINE and International Pharmaceutical Abstracts (since 1990) to identify community and ambulatory pharmacy intervention studies which aimed to improve medication adherence. The authors also searched the primary literature using Ovid to identify studies related to the pharmacy teaching of medication adherence. The bibliographies of relevant studies were reviewed in order to identify additional literature. We searched the tables of content of three US pharmacy education journals and reviewed the American Association of Colleges of Pharmacy website for materials on teaching adherence principles. Policies related to medication adherence were identified based on what was commonly known to the authors from professional experience, attendance at professional meetings, and pharmacy journals.

Results

Research and Practice: 29 studies were identified: 18 randomized controlled trials; 3 prospective cohort studies; 2 retrospective cohort studies; 5 case-controlled studies; and one other study. There was considerable variability in types of interventions and use of adherence measures. Many of the interventions were completed by pharmacists with advanced clinical backgrounds and not typical of pharmacists in community settings. The positive intervention effects had either decreased or not been sustained after interventions were removed. Although not formally assessed, in general, the average community pharmacy did not routinely assess and/or intervene on medication adherence.

Education

National pharmacy education groups support the need for pharmacists to learn and use adherence-related skills. Educational efforts involving adherence have focused on students’ awareness of adherence barriers and communication skills needed to engage patients in behavioral change.

Policy

Several changes in pharmacy practice and national legislation have provided pharmacists opportunities to intervene and monitor medication adherence. Some of these changes have involved the use of technologies and provision of specialized services to improve adherence.

Conclusions

Researchers and practitioners need to evaluate feasible and sustainable models for pharmacists in community settings to consistently and efficiently help patients better use their medications and improve their health outcomes.

A cluster randomized controlled Trial to Evaluate an Ambulatory primary care Management program for patients with dyslipidemia: the TEAM study

BACKGROUND

Few studies have reported the efficacy of collaborative care involving family physicians and community pharmacists for patients with dyslipidemia.

METHODS

We randomly assigned clusters consisting of at least two physicians and at least four pharmacists to provide collaborative care or usual care. Under the collaborative care model, pharmacists counselled patients about their medications, requested laboratory tests, monitored the effectiveness and safety of medications and patients' adherence to therapy, and adjusted medication dosages. After 12 months of follow-up, we assessed changes in low-density lipoprotein (LDL) cholesterol (the primary outcome), the proportion of patients reaching their target lipid levels and changes in other risk factors.

RESULTS

Fifteen clusters representing a total of 77 physicians and 108 pharmacists were initially recruited, and a total of 51 physicians and 49 pharmacists were included in the final analyses. The collaborative care teams followed a total of 108 patients, and the usual care teams followed a total of 117 patients. At baseline, mean LDL cholesterol level was higher in the collaborative care group (3.5 v. 3.2 mmol/L, p = 0.05). During the study, patients in the collaborative care group were less likely to receive high-potency statins (11% v. 40%), had more visits with health care professionals and more laboratory tests, were more likely to have their lipid-lowering treatment changed and were more likely to report lifestyle changes. At 12 months, the crude incremental mean reduction in LDL cholesterol in the collaborative care group was -0.2 mmol/L (95% confidence interval [CI] -0.3 to -0.1), and the adjusted reduction was -0.05 (95% CI -0.3 to 0.2). The crude relative risk of achieving lipid targets for patients in the collaborative care group was 1.10 (95% CI 0.95 to 1.26), and the adjusted relative risk was 1.16 (95% CI 1.01 to 1.34).

INTERPRETATION

Collaborative care involving physicians and pharmacists had no significant clinical impact on lipid control in patients with dyslipidemia. International Standard Randomized Controlled Trial register no. ISRCTN66345533.

Use of specialty care versus standard retail pharmacies for treatment of hepatitis C

BACKGROUND

Treatment for hepatitis C virus (HCV) is associated with significant adverse events. Improved adherence increases the probability of achieving sustained virologic response (SVR). Despite a lack of supporting literature, the use of specialty care pharmacies has increased in recent years in an attempt to improve HCV treatment outcomes.

OBJECTIVE

To compare specialty care versus standard retail pharmacies in HCV treatment outcomes, utilization of office resources, and the use of supplemental medications.

METHODS

A retrospective chart review was performed at a single academic institution for adults with HCV infection treated between 2001 and 2006. SVR was the primary endpoint. Secondary endpoints included therapy completion rates, HCV treatment dose reductions, additional phone calls and clinic visits, and the use of supplemental medications.

RESULTS

One hundred ninety-seven patients were identified (102 standard and 95 specialty care pharmacy). There were no differences in baseline demographics between the groups, except for a higher proportion of African Americans using specialty care pharmacies. Overall SVR was 103/197 (52%). SVR was 57/102 (56%) in the standard pharmacy group and 46/95 (48%) in the specialty care pharmacy group. There were no statistically significant differences with regard to SVR (even after accounting for differences in ethnicity), the use of supplemental medications, additional clinic phone calls and visits required, and the reasons for HCV therapy discontinuation. There was a statistically significantly higher incidence of HCV medication dose reductions in the standard retail pharmacy group (45% vs 28%; p = 0.016).

CONCLUSIONS

The use of specialty care pharmacies for the treatment of HCV was not associated with higher SVR rates. Patients using specialty care pharmacies had a lower incidence of interferon and/or ribavirin dose reductions, but there was no difference between the groups in therapy completion rates, use of additional office resources, or use of supplemental medications.

Sensitivity of Patient Outcomes to Pharmacist Interventions. Part III: Systematic Review and Meta-Analysis in Hyperlipidemia Management

Background

Hyperlipidemia increases the risk of cardiovascular diseases, and control is pivotal ror preventing disease complications. Multidisciplinary interventions, including those performed by pharmacists, are important for improving patients’ outcomes.

Objective:

To quantify the impact of pharmacist interventions in enhancing patients’ outcomes.

Methods

TWO reviewers searched International Pharmaceutical Abstracts, MEDLINE, EMBASE, The Cochrane Central Register of Controlled Trials. 3rd Quarter, and Cumulative Index to Nursing and Allied Health Literature (all from inception to July 2007) for pharmacist interventions in hyperlipidemia. Quality was assessed using the Downs-Black scale. Data extracted included the number of patients enrolled; study characteristics; intervention type; and pre- and postintervention measures for low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, total cholesterol, adherence, and quality of life. A random effects meta-analysis combined data. Heterogeneity of effects was tested using χ5 analysis. Publication bias was assessed using funnel plots and the Begg-Mazumdar statistic.

Results:

Forty-eight studies were found; 23 met inclusion criteria. Study settings included medical clinic/center (n = 12), community pharmacy (n = 8), hospital (n = 2), and patient homes (n = 1). Article quality was good (71% ± 7.0%). Patient education (78%) and medication management (74%) were the most common interventions. Total cholesterol was significantly reduced from baseline (mean ± SD; 34.3 ± 10.3 mg/dL; p < 0.001) and above that for controls (22.0 ± 10.4 mg/dL: p = 0.034). LDL-C was reduced significantly from baseline (32.6 ± 11.3 mg/dL; p = 0.004), but not significantly more than controls (17.5 ± 10.9 mg/dL; p = 0.109). A clinically relevant but not statistically significant reduction in triglycerides was found. No impact on HDL-C levels was found. Patients’ adherence to pharmacotherapeutic regimens and quality of life were considered possibly not sensitive and possibly sensitive to pharmacist interventions, respectively.

Conclusions:

Total cholesterol is sensitive to pharmacist interventions, while LDL-C and triglyceride levels are possibly sensitive to those interventions. Further research is required for these outcomes.

Use of maximum-dose simvastatin or atorvastatin in an ethnically diverse population

PURPOSE

The use of maximum-dose simvastatin or atorvastatin in an ethnically diverse population was studied.

METHODS

This retrospective analysis was conducted at a publicly funded teaching institution whose predominant patient population consists of Hispanics and Asians. A computer-generated report was used to identify outpatients who received a prescription for maximum-dose simvastatin or atorvastatin between January 1, 2002, and January 1, 2004. Data evaluated included demographic information; metabolic syndrome elements; coronary heart disease (CHD) risk equivalents; clinical characteristics placing patients at very high risk of having a CHD event; 10-year Framingham risk score; documentation of hepatotoxicity, myalgia, myositis, or rhabdomyolysis during maximum-dose therapy; concomitant medication during maximumdose therapy; relevant laboratory test values; and physician response to biochemical abnormalities or adverse events associated with maximum-dose therapy.

RESULTS

Of the 232 outpatients identified, 173 were eligible for study inclusion. A total of 135 patients were classified as having a high or very-high risk of developing CHD (68 and 67, respectively). The success rates for low-density-lipoprotein (LDL) cholesterol goal attainment by very-high-risk patients and high-risk patients were 19.4% and 44.1%, respectively. Thirteen patients developed myalgia. Alanine transaminase levels were monitored for 38.8% of the study patients. Approximately 9% of patients were prescribed one interacting medication while on maximum-dose simvastatin or atorvastatin. The most commonly prescribed interacting drug was gemfibrozil.

CONCLUSION

Despite the use of maximum-dose simvastatin or atorvastatin, target LDL cholesterol goals were not achieved and statin use was not adequately monitored in an ethnically diverse population with a high or very high risk of developing CHD.

Provision of pharmacotherapy services in a rural nurse practitioner clinic

PURPOSE

Clinical pharmacy interventions and services provided in collaboration with a nurse practitioner in a medically underserved rural health center are described.

METHODS

Data were collected via retrospective chart review of clinical pharmacy notes for all patients referred to the clinical pharmacist from July 2001 through February 2004. Data collected included demographic information, reasons for referral, duration of follow-up, insurance status, use of medication assistance programs, educational interventions, clinical interventions, and clinical outcomes. Changes in mean low-density-lipoprotein (LDL) cholesterol levels, blood pressures, and glycosylated hemoglobin (HbA(1c)) were analyzed using a paired Student's t test. Smoking cessation, the number of times the international normalized ratio (INR) was in a goal range, and attainment of goal LDL cholesterol, blood pressure, and HbA(1c) levels were also recorded.

RESULTS

Clinical pharmacy interventions were summarized for 101 patients who were seen in 708 patient visits. A mean of 5.6 educational interventions were provided per visit, and a mean of 1.0 clinical intervention occurred per visit. Initiation of new drug therapy or dosage adjustment accounted for 52% of the clinical interventions. A large percentage of patients attained their goals for LDL cholesterol (76%), blood pressure (86%), HbA(1c) (69%), INR (82%), and smoking cessation (43%) during the study period.

CONCLUSION

Pharmacotherapy services provided by a clinical pharmacist at a rural nurse practitioner clinic positively affected clinical outcomes and increased patients' attainment rates for LDL cholesterol, systolic and diastolic blood pressures, and HbA(1c).

Achievement of optimal combined lipid values in a managed care setting: Is a new treatment paradigm needed?

BACKGROUND

Published guidelines suggest the management of high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) values after the low-density lipoprotein cholesterol (LDL-C) goal is achieved.

OBJECTIVE

This study evaluated the attainment of optimal combined lipid values (LDL-C, HDL-C, and TGs) and associated therapy over time.

METHODS

This retrospective cohort analysis was conducted among managed-care patients who had a baseline lipid panel taken between October 1, 1999, and September 30, 2000; were naive to lipid therapy; and had plan eligibility for at least 12 months before and 12 to 36 months after the baseline lipid values. Patients were categorized as elevated-risk primary prevention (ERP) or as coronary heart disease (CHD) and CHD risk equivalents (CHD-RE). The attainment of optimal combined lipid values was assessed at baseline and quarterly thereafter. Associations between lipid values and the use of lipid-altering therapy were assessed using multivariate logistic regression.

RESULTS

A total of 30,348 patients were monitored for a mean (SD) duration of 27 (8) months. Mean (SD) age was 66 (12) years and 55% (16,549/30,348) were men; 43% (13,059/30,348) were categorized as ERP and 57% (17,289/30,348) as CHD-RE. Combined lipid values were optimal in 14% (4167/30,348),18% (5508/30,348), and 22% (2936/13,100) of patients at baseline, 12 months, and 36 months, respectively. After 36 months, 78% (10,164/13,100) of patients did not attain optimal combined lipid values. Lipid therapy, primarily statin monotherapy (87% [7992/ 92251), was prescribed in 30% (9225/30,348) of patients. After 36 months, 34% (4492/13,100) of patients had isolated elevated LDL-C and 20% (2588/13,100) had non-optimal HDL-C and/or TGs. Lipid therapy was associated with the attainment of optimal combined values for LDL-C and TGs (both, P < 0.05), but not for HDL-C. Because the study was retrospective, causality cannot be determined.

CONCLUSIONS

Based on the results of this study, use of combination lipid therapy and targeted therapy aimed at the specific lipid abnormalities may increase the attainment of optimal lipid parameters.

Workplace-Based Cardiovascular Risk Management by Community Pharmacists: Impact on Blood Pressure, Lipid Levels, and Weight

STUDY OBJECTIVE

To assess the effectiveness of a community pharmacist-delivered cardiovascular case-management program by comparing body mass index (weight), systolic and diastolic blood pressure, and full lipid profile at the beginning of the program with these outcome measures at the end of the program.

DESIGN

Retrospective data analysis using billing data submitted between July 1, 2001, and October 31, 2004, with a pre-post design in which subjects served as their own controls.

SETTING

Manufacturing workplace in rural Iowa.

PARTICIPANTS

Fifty-six workers with risk factors for cardiovascular disease (mean age 40.67 yrs), 37 had diabetes mellitus and 19 did not.

INTERVENTION

During visits to the workers, pharmacists provided education about cardiovascular disease, identification of drug therapy problems, and importance of routine blood pressure, pulse, and weight measurements; they communicated with participants' physicians as needed.

MEASUREMENTS AND MAIN RESULTS

The number of pharmacist visits/participant ranged from 1-13 (mean +/- SD 6.97 +/- 3.05). Outcome measures were weight, systolic and diastolic blood pressures, full lipid profiles (in patients with diabetes), and percentage of patients achieving treatment goal by the end of the 3 years. Statistically significant differences between the first and last visits were achieved for both systolic (124.12 +/- 11.07 and 120.36 +/- 14.39 mm Hg, respectively, p=0.016) and diastolic (80.4 +/- 9.01 and 77.43 +/- 9.14 mm Hg, respectively, p=0.019) blood pressure. The 19 patients without diabetes showed a statistically significant improvement in diastolic blood pressure (p=0.039), but the 37 patients with diabetes did not show a significant difference. A nonsignificant increase was seen in the percentage of patients with diabetes achieving low-density lipoprotein cholesterol (LDL) level goal between the first and last visits (p=0.06).

CONCLUSION

A cardiovascular case-management program delivered in the workplace to middle-aged working adults by community pharmacists improved blood pressure and reduced LDL levels. The program was not effective, however, in weight reduction.

Evaluation of patient and provider satisfaction with a pharmacist-managed lipid clinic in a Veterans Affairs medical center

PURPOSE

Patient and provider satisfaction with a pharmacist-managed lipid clinic in a Veterans Affairs medical center were assessed.

METHODS

All patients at Louis Stokes Cleveland Veterans Affairs Medical Center who were referred to a pharmacist-managed lipid clinic for drug therapy management were mailed a questionnaire addressing overall satisfaction with care provided by the lipid clinic. Chart reviews were performed for patients completing the questionnaire to ascertain lipid-lowering medications used, changes in serum cholesterol levels, and achievement of low-density-lipoprotein (LDL) cholesterol goal. Health care providers referring patients to the lipid clinic were sent an anonymous electronic questionnaire to assess provider satisfaction with the clinic. Responses to the questionnaire were rated on a Likert scale (strongly agree, somewhat agree, neutral, somewhat disagree, strongly disagree). A paired t test was used to assess the percent change in lipid values, and chi-square analysis was used to evaluate the achievement of each patient's LDL cholesterol goal.

RESULTS

Surveys were sent to 224 patients and 104 providers. A total of 105 patients (47%) and 49 providers (47%) completed the questionnaire. Most patients and providers expressed satisfaction with the clinic, with 91.4% of patients and 87.8% of providers indicating that they were strongly or somewhat satisfied with the care provided by the pharmacist-managed clinic. Attainment rates of goal LDL cholesterol levels increased from 8.6% at baseline to 53.3% at discharge or the most recent measurement (p < 0.001).

CONCLUSION

Most patients and providers were satisfied with the services provided by the pharmacist-managed lipid clinic. The clinic helped improve patients' LDL cholesterol, total cholesterol, and triglyceride levels.

Patient education and treatment strategies implemented at a pharmacist-managed hepatitis C virus clinic

Hepatitis C virus (HCV) infection is a major public health concern. Approximately 4 million people in the United States have been infected with the virus, and up to 85% of them will develop chronic infection. Chronic HCV infection has often been associated with progression of hepatic fibrosis and, in some cases, cirrhosis and end-stage liver disease. The standard of care is combination therapy with pegylated interferon (peginterferon) alfa plus ribavirin. More than 50% of patients with HCV treated with combination therapy achieve a sustained viral response, defined as undetectable hepatitis C viral RNA 6 months after the end of therapy. Effective patient education and drug therapy management are critical in enabling patients to adhere to the treatment regimen, which is either 24 or 48 weeks long, depending on the virus strain. The drug regimen is associated with several possible adverse events as well as weekly subcutaneous administration (of peginterferon alfa). Frequent monitoring of patients and, often, adjustments in the dosage of one or both components of the therapy are necessary during the treatment course. Strategies used by clinical pharmacists at an HCV clinic are discussed that can facilitate a successful treatment outcome for patients with HCV treated with combination therapy, while enabling them to maintain a reasonable quality of life.

Evidence-based interventions to improve patient compliance with antihypertensive and lipid-lowering medications

The MEDLINE database was searched from 1972 to June 2002 to identify studies of interventions designed to improve compliance with antihypertensive or lipid-lowering medications. Studies were required to employ a controlled design, follow patients for >or=6 months and measure compliance by a method other than patient self-report. The literature review yielded 62 studies describing 79 interventions. Overall, 56% of interventions were reported to improve patient compliance. When only those studies meeting minimum criteria for methodological quality were considered, 22 interventions remained and 12 were recommended, because they demonstrated a significant improvement in compliance. Recommended interventions included fixed-dose combination drugs, once-daily or once-weekly dosing schedules, unit-dose packaging, educational counselling by telephone, case management by pharmacists, treatment in pharmacist- or nurse-operated disease management clinics, mailed refill reminders, self-monitoring, dose-tailoring, rewards and various combination strategies. Personalised, patient-focused programs that involved frequent contact with health professionals or a combination of interventions were the most effective at improving compliance. Less-intensive strategies, such as prescribing products that simplify the medication regimen or sending refill reminders, achieved smaller improvements in compliance but may be cost-effective due to their low cost.

Heart healthy and stroke free: successful business strategies to prevent cardiovascular disease

BACKGROUND

Heart disease and stroke, the principal components of cardiovascular disease (CVD), are the first and third leading causes of death in the United States. In 2002, employers representing 88 companies in the United States paid an average of 18,618 dollars per employee for health and productivity-related costs. A sizable portion of these costs are related to CVD.

RESULTS

Employers can yield a 3 dollar to 6 dollar return on investment for each dollar invested over a 2 to 5 year period and improve employee cardiovascular health by investing in comprehensive worksite health-promotion programs, and by choosing health plans that provide adequate coverage and support for essential preventive services. The most effective interventions in worksites are those that provide sustained individual follow-up risk factor education and counseling and other interventions within the context of a comprehensive health-promotion program: (1) screening, health risk assessments, and referrals; (2) environmental supports for behavior change (e.g., access to healthy food choices); (3) financial and other incentives; and (4) corporate policies that support healthy lifestyles (e.g., tobacco-free policies). The most effective practices in healthcare settings include systems that use (1) standardized treatment and prevention protocols consistent with national guidelines, (2) multidisciplinary clinical care teams to deliver quality patient care, (3) clinics that specialize in treating/preventing risk factors, (4) physician and patient reminders, and (5) electronic medical records.

CONCLUSIONS

Comprehensive worksite health-promotion programs, health plans that cover preventive benefits, and effective healthcare systems will have the greatest impact on heart disease and stroke and are likely to reduce employers' health and productivity-related costs.

A randomized trial of a primary care-based disease management program to improve cardiovascular risk factors and glycated hemoglobin levels in patients with diabetes

PURPOSE

To assess the efficacy of a pharmacist-led, primary care-based, disease management program to improve cardiovascular risk factors and glycated hemoglobin (A(1C)) levels in vulnerable patients with poorly controlled diabetes.

METHODS

A randomized controlled trial of 217 patients with type 2 diabetes and poor glycemic control (A(1C) level >or=8.0%) was conducted at an academic general medicine practice from February 2001 to April 2003. Intervention patients received intensive management from clinical pharmacists, as well as from a diabetes care coordinator who provided diabetes education, applied algorithms for managing glucose control and decreasing cardiovascular risk factors, and addressed barriers to care. Control patients received a one-time management session from a pharmacist followed by usual care from their primary care provider. Outcomes were recorded at baseline and at 6 and 12 months. Primary outcomes included blood pressure, A(1C) level, cholesterol level, and aspirin use. Secondary outcomes included diabetes knowledge, satisfaction, use of clinical services, and adverse events.

RESULTS

For the 194 patients (89%) with 12-month data, the intervention group had significantly greater improvement than did the control group for systolic blood pressure (-9 mm Hg; 95% confidence interval [CI]: -16 to -3 mm Hg) and A(1C) level (-0.8%; 95% CI: -1.7% to 0%). Change in total cholesterol level was not significant. At 12 months, aspirin use was 91% in the intervention group versus 58% among controls (P <0.0001). Intervention patients had greater improvements in diabetes knowledge and satisfaction than did control patients. There were no significant differences in use of clinical services or adverse events.

CONCLUSION

Our comprehensive disease management program reduced cardiovascular risk factors and A(1C) levels among vulnerable patients with type 2 diabetes and poor glycemic control.

Achieving Cholesterol Target in a Managed Care Organization (ACTION) Trial

STUDY OBJECTIVES

To objectively compare the results of a collaborative approach using pharmacists with the results of usual care for achieving a low-density lipoprotein cholesterol (LDL) goal of 100 mg/dl or less in outpatients with documented coronary heart disease (CHD) who are not at goal, and to document the effect on LDL after removal of such a collaborative model from the study population.

DESIGN

Prospective, multiclinic, controlled study.

SETTING

Four clinics of a 19-clinic staff model health maintenance organization in Minneapolis and St. Paul, Minnesota. Two clinics treated the intervention patients, two the controls; one clinic for each group was suburban, and one for each was urban.

PATIENTS

Four hundred eighty-one patients aged 18 years or older with CHD and whose LDL levels were not at goal.

INTERVENTION

Clinical pharmacists implemented the physician-approved care plan for each intervention patient; activities included managing lipid-lowering drug therapy and educating patients on cardiovascular risk reduction.

MEASUREMENTS AND MAIN RESULTS

Primary outcomes were changes in LDL level and the proportion of patients achieving goal LDL in the intervention versus the usual care (control) group. Secondary outcomes were the sustainability of the impact observed up to 18 months after discontinuation of the intervention. Mean+/-SD baseline LDL levels were 131+/-28 and 131+/-26 mg/dl (p=NS) for the intervention and control groups, respectively. After a mean of 6.5 months follow-up, 107 (72%) patients in the intervention group and 61 (18%) patients in the control group had attained their LDL goal (p<0.001). Mean LDL levels were reduced by 35.6 mg/dl (27.5%) and 6.7 mg/dl (4.6%) in the intervention and control groups, respectively (p<0.001). When the active program was discontinued, results of the 18-month follow-up indicated that 85 (65%) intervention patients remained at goal compared with 96 (42%) controls (p<0.001).

CONCLUSION

This trial provides quantitative evidence to support the effectiveness of the collaborative approach as an intervention to optimize management of patients with CHD whose LDL levels are not at goal; this approach is specifically called for in the executive summary of the National Cholesterol Education Program Adult Treatment Panel III. Furthermore, this study documents both the magnitude and sustainability of the impact collaborative care models can have in managed care environments.

Cost of a pharmacist-directed intervention to increase treatment of hypercholesterolemia

STUDY OBJECTIVE

To evaluate the cost of a pharmacist-directed intervention that prompts physicians to treat hypercholesterolemia more aggressively in patients with coronary heart disease (CHD).

METHODS

Health care resource use and CHD outcomes were evaluated for 612 patients with CHD followed for 2 years after an index hospitalization for an ischemic event. After discharge, the physicians of 309 patients who had been admitted from January 1--March 31, 1999, were contacted by telephone and mail concerning lipid profiles and statin therapy. These patients were the intervention group. Controls were 303 patients admitted from October 1--December 31, 1998; their physicians were not contacted. Costs of the physician-prompting intervention, clinic visits, laboratory tests, statin drugs, and CHD outcomes were compared between these two patient groups.

RESULTS

The number of clinic visits, laboratory tests, and statins prescribed was significantly greater for the intervention group versus the controls. A significantly higher percentage of patients in the intervention group (55%) than in the control group (18%) achieved their National Cholesterol Education Program target low-density lipoprotein cholesterol level and had significantly better CHD outcomes. The cost of the physician-prompting intervention (pharmacist salaries, postage, telephone calls) was $102,941. For patients in the intervention and control groups, respectively, the cost of statin therapy was $352,365 and $200,087, the cost of clinic visits and laboratory tests $48,097 and $27,367, and the cost of coronary heart disease outcomes, such as myocardial infarction, coronary artery bypass graft, percutaneous transluminal and coronary angioplasty, $1,073,495 and $1,741,220. The total cost was $1,576,898 and $1,968,674, respectively, for patients in the intervention and control groups. Net savings was $1394/patient over the 2-year period.

CONCLUSION

A relatively simple physician-prompting intervention involving patients with CHD significantly improved the use of lipid testing and statin therapy. Improved use of statins was associated with better CHD outcomes. As a result, the physician-prompting intervention was associated with cost savings. This intervention should be implemented for patients with CHD discharged after hospitalization for an ischemic event.

Interventions to improve adherence to lipid lowering medication

BACKGROUND

Lipid lowering drugs are still widely underused, despite compelling evidence about their effectiveness in the treatment and prevention of cardiovascular disease. Poor patient adherence to medication regimen is a major factor in the lack of success in treating hyperlipidaemia. In this review we focus on interventions, which encourage patients at risk of heart disease or stroke to take lipid lowering medication regularly.

OBJECTIVES

To assess the effect of interventions aiming at improved adherence to lipid lowering drugs, focusing on measures of adherence and clinical outcomes.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycInfo and CINAHL. Date of most recent search was in February 2003. No language restrictions were applied.

SELECTION CRITERIA

Randomised controlled trials of adherence-enhancing interventions to lipid lowering medication in adults for both primary and secondary prevention of cardiovascular disease in an ambulatory setting.

DATA COLLECTION AND ANALYSIS

Two reviewers extracted data independently and assessed studies according to criteria outlined by the Cochrane Reviewers' Handbook.

MAIN RESULTS

The eight studies found contained data on 5943 patients. Interventions could be stratified into four categories : 1. simplification of drug regimen, 2. patient information/education, 3. intensified patient care such as reminding and 4. complex behavioural interventions such as group sessions. Change in adherence ranged from -3% to 25% (decrease in adherence by 3% to increase in adherence by 25%). Three studies reported significantly improved adherence through simplification of drug regimen (category 1), improved patient information/education (category 2) and reminding (category 3). The fact that the successful interventions were evenly spread across the categories, does not suggest any advantage of one particular type of intervention. The methodological and analytical quality was generally low and results have to be considered with caution. Combining data was not appropriate due to the substantial heterogeneity between included randomised controlled trials (RCTs).

REVIEWERS' CONCLUSIONS

At this stage, no specific intervention aimed at improving adherence to lipid lowering drugs can be recommended. The lack of a gold standard method of measuring adherence is one major barrier in adherence research. More reliable data might be achieved by newer methods of measurement, more consistency in adherence assessment and longer duration of follow-up. Increased patient-centredness with emphasis on the patient's perspective and shared-decision-making might lead to more conclusive answers when searching for tools to encourage patients to take lipid lowering medication.
