Underutilization of Evidence-Based Therapies in Heart Failure: The Pharmacist's Role

Drug-Therapy Problems and Predictors among Hospitalized Heart-Failure Patients: A Prospective Observational Study

BACKGROUND

Heart-failure patients are at high risk of experiencing drug-therapy problems, owing to polypharmacy, comorbidities, and usually advanced age. Drug-therapy problems can lead to poor clinical outcomes, increased health-care costs and decreased quality of life, and thus strategies for identifying, resolving, and preventing them are urgently needed. Therefore, this study aimed at investigating the incidence and predictors of drug-therapy problems among hospitalized heart-failure patients.

METHODS

This hospital-based prospective observational study was conducted from February 1 to May 31, 2014 at Jimma University Specialized Hospital. Patients of either sex aged 18 years and above with chronic heart failure and complete medical records were enrolled. Patients with high-output heart failure, <1 day of hospital stay, unwilling to give written informed consent, and unconscious without caregivers were excluded. Data were collected from medication charts, laboratory reports, patients/caregivers, morning multidisciplinary meetings, and ward rounds. Multivariate binary logistic regression analysis was done to identify independent predictors of drug-therapy problems.

RESULTS

A total of 104 heart-failure patients (mean age 51.20±15.66 years, females 51.9%) were consecutively enrolled, and 95 (91.3%) had experienced at least one drug-therapy problem (total 268, mean 2.82±1.39 encounters per patient). Of these problems, 45.5% were the need for additional drugs, followed by noncompliance (22.0%), inappropriate dosing (9.3%), unnecessary drugs (9.0%), ineffective drugs (8.2%), and adverse drug reactions (6.0%). None of the independent variables was found to be an independent predictor of having at least one drug-therapy problem. However, the number of clinical/pharmacological risk factors (AOR 7.93), female sex (AOR 3.24), and length of hospital stay (AOR 12.98) were predictors of noncompliance.

CONCLUSION

Patients suffered from a large number of drug-therapy problems. Drugs with survival benefit were underused. Noncompliance and the need for additional drug therapy were the most frequently identified drug-therapy problems. Numbers of clinical/pharmacological risk factors, length of hospital stay, and female sex were identified as predictors for noncompliance.

Current perspectives on the role of the pharmacist in heart failure management

Pharmacists play an important role within a multidisciplinary health care team in the care of patients with heart failure (HF). It has been evaluated and documented that pharmacists providing medication reconciliation especially during transition of care, educating patients on their medications, and providing collaborative medication management lead to positive changes in the patient outcomes, including but not limited to decreasing in hospitalizations and read-missions. It is foreseeable that pharmacist roles will continue to expand as new treatment and innovative care are developed for HF patients. I reviewed published role of pharmacists in the care of HF patients. MEDLINE and Current Content database (both from 1966 – December 31, 2017) were utilized to identify peer-reviewed clinical trials, descriptive studies, and review articles published in English using the following search terms: pharmacists, clinical pharmacy, HF, and cardiomyopathy. Citations from available articles were also reviewed for additional references. Preliminary search revealed 31 studies and 55 reviews. They were further reviewed by title and abstract as well as full text to remove irrelevant articles. At the end, 24 of these clinical trials and systematic reviews are described in the following text and Table 1 summarizes 16 pertinent clinical trials. Some roles that are currently being explored include medication management in patients with mechanical circulatory support for end-stage HF, where pharmacokinetics and pharmacodynamics of medications can change, medication management in ambulatory intravenous diuretic clinics, and comprehensive medication management in patients’ home settings. Pharmacists should continue to explore and prospectively evaluate their role in the care of this patient population, including documenting their interventions, and impact to economic and patient outcomes.

A Review of the Role of the Pharmacist in Heart Failure Transition of Care

This article reviews current literature on the role of pharmacists in the transition of care (TOC) for patients with heart failure (HF) and the impact of their contributions on therapeutic and economic outcomes. Optimizing the TOC for patients with HF from the hospital to the community/home is crucial for improving outcomes and decreasing high rates of hospital readmissions, which are associated with increased morbidity, mortality, and costs. A multidisciplinary team approach to the management of patients with HF facilitates the transition from the hospital to the ambulatory care setting, allowing for the consideration of medical, pharmacological, and lifestyle variables that impact the care of individual patients. Pharmacist participation on both inpatient and outpatient teams can provide a variety of services that have been shown to reduce hospital readmission rates and benefit patient management and treatment. These include medication reconciliation, patient education, medication dosage titration and adjustment, patient monitoring, development of disease management pathways, promotion of medication adherence, and postdischarge follow-up. In addition, as new pharmacologic treatments for HF become available, pharmacists can raise awareness of optimal drug use by maximizing education related to efficacy (e.g., adherence) and safety (e.g., potential side effects and drug interactions). Improving understanding of HF and its treatment will enable increased pharmacist involvement in the TOC that should lead to improved outcomes and reduced healthcare costs.

Treatment Considerations and the Role of the Clinical Pharmacist Throughout Transitions of Care for Patients With Acute Heart Failure

Heart failure is associated with increased risk of morbidity and mortality, resulting in substantial health-care costs. Clinical pharmacists have an opportunity to reduce health-care costs and improve disease management as patients transition from inpatient to outpatient care by leading interventions to develop patient care plans, educate patients and clinicians, prevent adverse drug reactions, reconcile medications, monitor drug levels, and improve medication access and adherence. Through these methods, clinical pharmacists are able to reduce rates of hospitalization, readmission, and mortality. In addition, care by clinical pharmacists can improve dosing levels and adherence to guideline-directed therapies. A greater benefit in patient management occurs when clinical pharmacists collaborate with other members of the health-care team, emphasizing the importance of heart failure treatment by a multidisciplinary health-care team. Education is a key area in which clinical pharmacists can improve care of patients with heart failure and should not be limited to patients. Clinical pharmacists should provide education to all members of the health-care team and introduce them to new therapies that may further improve the management of heart failure. The objective of this review is to detail the numerous opportunities that clinical pharmacists have to improve the management of heart failure and reduce health-care costs as part of a multidisciplinary health-care team.

Team-Based Care for Outpatients with Heart Failure

Management of heart failure requires a multidisciplinary team-based approach that includes coordination of numerous team members to ensure guideline-directed optimization of medical therapy, frequent and regular assessment of volume status, frequent education, use of cardiac rehabilitation, continued assessment for the use of advanced therapies, and advance care planning. All of these are important aspects of the management of this complex condition.

Nurse Practitioner Practice Patterns for Management of Heart Failure in Long-Term Care Facilities

Purpose: This study examined nurse practitioners’ (NPs) practice patterns for heart failure (HF) management, specifically regarding the use of angiotensin-converting enzyme inhibitors (ACEIs), beta antagonists, diuretic monotherapy, and echocardiograms for older adults residing in long-term care facilities. Methodology: A Web-based survey was developed to identify NP practice patterns for HF management in long-term care settings. The Checklist for Reporting Results of Internet E-Surveys and expert opinion guided the survey design. The survey was distributed via e-mail to Gerontological Advanced Practice Nurses Association members. Results: Most NPs used ACEIs for ongoing therapy, initiated appropriate therapy for symptomatic patients, continued beta-antagonist therapy in patients with HF, used echocardiograms in the diagnosis and evaluation of HF, and prescribed monotherapy diuretics in accordance with HF care standards. Implications for Practice: Based on these findings, NP practice patterns for management of HF in the long-term care setting are in alignment with national standard of care regardless of certification or level of physician oversight. NPs need to be cognizant of the cardiovascular risk factors for HF and adjust treatment to add an ACEI or beta antagonist to diuretic monotherapy when the clinical diagnosis of HF is suspected or established.

Prescribing Data in General Practice Demonstration (PDGPD) project--a cluster randomised controlled trial of a quality improvement intervention to achieve better prescribing for chronic heart failure and hypertension

BACKGROUND

Research literature consistently documents that scientifically based therapeutic recommendations are not always followed in the hospital or in the primary care setting. Currently, there is evidence that some general practitioners in Australia are not prescribing appropriately for patients diagnosed with 1) hypertension (HT) and 2) chronic heart failure (CHF). The objectives of this study were to improve general practitioner's drug treatment management of these patients through feedback on their own prescribing and small group discussions with peers and a trained group facilitator. The impact evaluation includes quantitative assessment of prescribing changes at 6, 9, 12 and 18 months after the intervention.

METHODS

A pragmatic multi site cluster RCT began recruiting practices in October 2009 to evaluate the effects of a multi-faceted quality improvement (QI) intervention on prescribing practice among Australian general practitioners (GP) in relation to patients with CHF and HT. General practices were recruited nationally through General Practice Networks across Australia. Participating practices were randomly allocated to one of three groups: two groups received the QI intervention (the prescribing indicator feedback reports and small group discussion) with each group undertaking the clinical topics (CHF and HT) in reverse order to the other. The third group was waitlisted to receive the intervention 6 months later and acted as a "control" for the other two groups.De-identified data on practice, doctor and patient characteristics and their treatment for CHF and HT are extracted at six-monthly intervals before and after the intervention. Post-test comparisons will be conducted between the intervention and control arms using intention to treat analysis and models that account for clustering of practices in a Network and clustering of patients within practices and GPs.

DISCUSSION

This paper describes the study protocol for a project that will contribute to the development of acceptable and sustainable methods to promote QI activities within routine general practice, enhance prescribing practices and improve patient outcomes in the context of CHF and HT.

Utilization of evidence-based treatment in elderly patients with chronic heart failure: using Korean Health Insurance claims database

Background

Chronic heart failure accounts for a great deal of the morbidity and mortality in the aging population. Evidence-based treatments include angiotensin-2 receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACE-I), beta-blockers, and aldosterone antagonists. Underutilization of these treatments in heart failure patients were frequently reported, which could lead to increase morbidity and mortality. The aim of this study was to evaluate the utilization of evidence-based treatments and their related factors for elderly patients with chronic heart failure.

Methods

This is retrospective observational study using the Korean National Health Insurance claims database. We identified prescription of evidence based treatment to elderly patients who had been hospitalized for chronic heart failure between January 1, 2005, and June 30, 2006.

Results

Among the 28,922 elderly patients with chronic heart failure, beta-blockers were prescribed to 31.5%, and ACE-I or ARBs were prescribed to 54.7% of the total population. Multivariable logistic regression analyses revealed that the prescription from outpatient clinic (prevalent ratio, 4.02, 95% CI 3.31–4.72), specialty of the healthcare providers (prevalent ratio, 1.26, 95% CI, 1.12–1.54), residence in urban (prevalent ratio, 1.37, 95% CI, 1.23–1.52) and admission to tertiary hospital (prevalent ratio, 2.07, 95% CI, 1.85–2.31) were important factors associated with treatment underutilization. Patients not given evidence-based treatment were more likely to experience dementia, reside in rural areas, and have less-specialized healthcare providers and were less likely to have coexisting cardiovascular diseases or concomitant medications than patients in the evidence-based treatment group.

Conclusions

Healthcare system factors, such as hospital type, healthcare provider factors, such as specialty, and patient factors, such as comorbid cardiovascular disease, systemic disease with concomitant medications, together influence the underutilization of evidence-based pharmacologic treatment for patients with heart failure.

A new leadership role for pharmacists: a prescription for change

OBJECTIVE

Pharmacists can play an important role as leaders to reduce patient safety risks, optimize the safe function of medication management systems, and align pharmacy services with national initiatives that measure and reward quality performance. The objective of this article is to determine the actions that pharmacists can take to create a visible and sustainable safe medication management structure and system in the health care environment.

METHODS

An evidence-based literature search was performed to determine what actions successful pharmacist leaders have taken to improve patient safety.

RESULTS

There is a growing number of quality and patient safety standards, as well as measures that focus specifically on medication use and education. Health care organizations must be made aware of the valuable resources that pharmacists provide and of the complexity of medication management. There are steps that pharmacist leaders can take to achieve these goals.

CONCLUSIONS

The 10 steps that pharmacist leaders can take to create a visible and sustainable safe medication management structure and system are the following: 1. Identify and mitigate medication management risks and hazards to reduce preventable patient harm. 2. Establish pharmacy leadership structures and systems to ensure organizational awareness of medication safety gaps. 3. Support an organizational culture of safe medication use. 4. Ensure evidence-based medication regimens for all patients. 5. Have daily check-in calls/meetings, with the primary focus on significant safety or quality issues. 6. Establish a medication safety committee. 7. Perform medication safety walk-rounds to evaluate medication processes, and request front-line staff ’s input about medication safe practices. 8. Ensure that pharmacy staff engage in teamwork, skill building, and communication training. 9. Engage in readiness planning for implementation of health information technology (HIT). 10. Include medication history-taking and reviews upon entry into the organization; medication counseling and training during the discharge process; and follow-up after the transition to home.
