Attitudes toward deprescribing among adults with heart failure with preserved ejection fraction

Heart failure with mildly reduced and preserved ejection fraction: A review of disease burden and remaining unmet medical needs within a new treatment landscape

This review provides a comprehensive overview of heart failure with mildly reduced and preserved ejection fraction (HFmrEF/HFpEF), including its definition, diagnosis, and epidemiology; clinical, humanistic, and economic burdens; current pharmacologic landscape in key pharmaceutical markets; and unmet needs to identify key knowledge gaps. We conducted a targeted literature review in electronic databases and prioritized articles with valuable insights into HFmrEF/HFpEF. Overall, 27 randomized controlled trials (RCTs), 66 real-world evidence studies, 18 clinical practice guidelines, and 25 additional publications were included. Although recent heart failure (HF) guidelines set left ventricular ejection fraction thresholds to differentiate categories, characterization and diagnosis criteria vary because of the incomplete disease understanding. Recent epidemiological data are limited and diverse. Approximately 50% of symptomatic HF patients have HFpEF, more common than HFmrEF. Prevalence varies with country because of differing definitions and study characteristics, making prevalence interpretation challenging. HFmrEF/HFpEF has considerable mortality risk, and the mortality rate varies with study and patient characteristics and treatments. HFmrEF/HFpEF is associated with considerable morbidity, poor patient outcomes, and common comorbidities. Patients require frequent hospitalizations; therefore, early intervention is crucial to prevent disease burden. Recent RCTs show promising results like risk reduction of composite cardiovascular death or HF hospitalization. Costs data are scarce, but the economic burden is increasing. Despite new drugs, unmet medical needs requiring new treatments remain. Thus, HFmrEF/HFpEF is a growing global healthcare concern. With improving yet incomplete understanding of this disease and its promising treatments, further research is required for better patient outcomes.

Unlocking Deprescribing Potential in Nursing Homes: Insights from a Focus Group Study with Healthcare Professionals

BACKGROUND

The nursing home population is characterized by multimorbidity and disabilities, which often result in extensive prescription of medication and subsequent polypharmacy. Deprescribing, a planned and supervised process of dose reduction or total cessation of medication, is a solution to combat this.

OBJECTIVE

This study aimed to identify barriers and enablers of deprescribing as experienced by nursing home physicians (NHPs) and collaborating pharmacists in the specific nursing home setting.

METHODS

This qualitative study utilized a semi-structured interview format with two focus groups consisting of a mix of NHPs and pharmacists. Directed content analysis was performed based on the Theoretical Domains Framework, a validated framework for understanding determinants of behavior change among health care professionals.

RESULTS

Sixteen health care professionals participated in two focus groups, including 13 NHPs and three pharmacists. The participating NHPs and pharmacists believed that deprescribing is a valuable process with enablers, such as multidisciplinary collaboration, good communication with patients and family, and involvement of the nursing staff. NHPs and pharmacists view deprescribing as a core task and feel assured in their ability to carry it out successfully. However, they also noted barriers: deprescribing is time-consuming; communication with residents, their relatives or medical specialists is difficult; and electronic patient systems often do not adequately support it.

CONCLUSIONS

This study provides insight into the various barriers and enablers faced by NHPs and pharmacists when deprescribing in nursing homes. Specific for this population, deprescribing barriers focus on communication (with residents and their relatives, and also with medical specialists) and resources, while knowledge and expertise are mentioned as enablers.

Does missing data matter in the revised Patients' Attitudes Towards Deprescribing questionnaire? A systematic review and two case analyses

BACKGROUND

The revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire was developed to capture beliefs and perceptions of patients about deprescribing. In general, handling of missing data is underreported in survey studies. Underlying mechanisms related to missing data may impact the findings from survey studies.

OBJECTIVES

The aim of this study was to assess the missing data in studies using the rPATD questionnaire through a systematic review and datasets from two studies.

METHODS

First, this review updated a systematic review on the rPATD (and other versions). We searched Medline via OVID, EMBASE, Scopus, Web of Science until 31st January 2023. Missing data reporting and methods to handle them were collected. Second, data from two deprescribing studies were analyzed using three methods of missing data handling: complete case analysis, personal mean substitution, and multiple imputation. We compared the scores from each domain and the associations of the domains with two questions from the rPATD to highlight how using different methods can influence the interpretation of study findings.

RESULTS

We identified 49 studies: 31 (63 %) from this study and 18 (37 %) from the original systematic review. The question or domain with the most missing data could be identified in 9 studies (18.4 %). Missing data management was reported in 19 studies (38.8 %). In one case analysis, the "Burden" domain was significantly associated with the question "I would like to try stopping one of my medicines to see how I feel without it" using complete case analysis (p = 0.044) or multiple imputation (p = 0.038), but not when using personal mean substitution (p = 0.057).

CONCLUSIONS

Missing data and methods used to handle missing data were underreported in studies using the rPATD questionnaire. The methods should be chosen carefully as our analyses from two distinct studies suggest that they may impact the interpretation of the findings from the questionnaire.

Older adults' attitudes towards deprescribing and medication changes: a longitudinal sub-study of a cluster randomised controlled trial

OBJECTIVE

To investigate the association between older patients' willingness to have one or more medications deprescribed and: (1) change in medications, (2) change in the appropriateness of medications and (3) implementation of prescribing recommendations generated by the electronic decision support system tested in the 'Optimising PharmacoTherapy In the Multimorbid Elderly in Primary CAre' (OPTICA) trial.

DESIGN

A longitudinal sub-study of the OPTICA trial, a cluster randomised controlled trial.

SETTING

Swiss primary care settings.

PARTICIPANTS

Participants were aged ≥65 years, with ≥3 chronic conditions and ≥5 regular medications recruited from 43 general practitioner (GP) practices.

EXPOSURES

Patients' willingness to have medications deprescribed was assessed using three questions from the 'revised Patient Attitudes Towards Deprescribing' (rPATD) questionnaire and its concerns about stopping score.

MEASURES/ANALYSES

Medication-related outcomes were collected at 1 year follow-up. Aim 1 outcome: change in the number of long-term medications between baseline and 12 month follow-up. Aim 2 outcome: change in medication appropriateness (Medication Appropriateness Index). Aim 3 outcome: binary variable on whether any prescribing recommendation generated during the OPTICA medication review was implemented. We used multilevel linear regression analyses (aim 1 and aim 2) and multilevel logistic regression analyses (aim 3). Models were adjusted for sociodemographic variables and the clustering effect at GP level.

RESULTS

298 patients completed the rPATD, 45% were women and 78 years was the median age. A statistically significant association was found between the concerns about stopping score and the change in the number of medications over time (per 1-unit increase in the score the average number of medications use was 0.65 higher; 95% CI: 0.08 to 1.22). Other than that we did not find evidence for statistically significant associations between patients' agreement with deprescribing and medication-related outcomes.

CONCLUSIONS

We did not find evidence for an association between most measures of patient agreement with deprescribing and medication-related outcomes over 1 year.

Patient Attitudes Toward Deprescribing Among Community-Dwelling Older Mainers

Background The excess use of medications has become an increasingly prevalent issue in health care. Deprescribing can be an important tool in combating polypharmacy. Objective To assess the attitudes of community-dwelling older persons in Maine toward their medications and the concept of deprescription. An additional aim of this research was to assess the association between the revised Patient Attitudes Toward Deprescribing Questionnaire (rPATDQ) domains by polypharmacy status. Methods Researchers conducted a cross-sectional study utilizing the rPATDQ. Authors recruited older Mainers via a longitudinal cohort study through the University of New England Center for Excellence in Aging in Health. Respondents were stratified by polypharmacy status (fewer than five medications, five or more medications). Results Total daily medications ranged from 1 to 30 (average of 8.6). Overall, 83.6% of respondents agreed/strongly agreed to the statement "If my doctor said it was possible, I would be willing to stop one or more of my regular medicines." 70.6% agreed/ strongly agreed to the statement "Overall, I am satisfied with my current medicines." Those with and without polypharmacy experienced low overall medication burden and a high belief in the appropriateness of their medications. There were no statistically significant differences between polypharmacy groups. Conclusion The results of this survey indicate that the factors affecting attitudes toward deprescribing are complex. While many indicated willingness to deprescribe at least one medication, there was a high degree of satisfaction with current medication regimens. This study highlights the need for further qualitative research to identify potential barriers to deprescribing.

Predictors of older patients' willingness to have medications deprescribed: A cross-sectional study

BACKGROUND

Deprescribing is a complex process requiring a patient-centred approach. One frequently expressed deprescribing barrier is patients' attitudes and beliefs towards deprescribing. This study aimed to identify the predictors of patients' willingness to have medications deprescribed.

METHODS

A cross-sectional study was conducted with community-dwelling patients aged ≥65 who are taking at least one regular medication. Data collection included patients' demographic and clinical characteristics and the Portuguese revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Descriptive statistics were used to present the patients' characteristics. Multiple binary logistic regression analysis was performed to identify the predictors of the patients' willingness to have medications deprescribed.

RESULTS

One hundred ninety-two participants (median age 72 years; 65.6% female) were included. Most (83.33%) were willing to have medications deprescribed, and the predictors were age (adjusted odds ratio [aOR] = 1.136; 95% CI 1.026, 1.258), female sex (aOR = 3.036; 95% CI 1.059, 8.708) and the rPATD concerns about stopping factor (aOR = 0.391; 95% CI 0.203, 0.754).

CONCLUSIONS

Most patients were willing to have their medications deprescribed if it is recommended by their doctors. Older age and female sex increased the odds of willingness to deprescribe; higher concerns about stopping medications decreased the odds. These findings suggest that addressing patients' concerns about stopping their medicines may contribute to deprescribing success.

Malnutrition in heart failure with preserved ejection fraction

BACKGROUND

Malnutrition may be an important geriatric condition in adults with heart failure with preserved ejection fraction (HFpEF), but studies on its prevalence and associated clinical outcomes are limited. The aim of this study was to determine if malnutrition is associated with short-term morbidity and mortality in ambulatory patients with HFpEF.

METHODS

We examined 231 patients with a clinical diagnosis of HFpEF seen at two dedicated academic HFpEF programs (Weill Cornell Medicine and Michigan Medicine) from June 2018 to April 2022. Malnutrition was defined by Mini-Nutritional Assessment Short Form (MNA-SF) scores ≤11. The primary endpoint was a 6-month composite of all-cause mortality and all-cause hospitalization. A Cox proportional-hazard models was used to examine the association between malnutrition and the primary endpoint, adjusting for race, prior hospitalization history, and the validated Meta-Analysis Global Group in Chronic (MAGGIC) heart failure prognostic risk score.

RESULTS

The median age of the cohort was 73 years (interquartile range 64-81). The most common comorbid conditions included hypertension (prevalence 81%), atrial fibrillation (43%), and obesity (63%). The prevalence of malnutrition was 42% (n = 97), and MNA-SF scores did not significantly correlate with body mass index (R = -0.02, p = 0.71). At the 6-month follow-up, 62 patients (26.8%) were hospitalized and four patients died (1.7%). In a fully-adjusted analysis, malnutrition was independently associated with the composite outcome of all-cause mortality and all-cause hospitalization (HR 1.94 [95% CI: 1.17-3.20], p = 0.01).

CONCLUSION

Despite a high prevalence of obesity, two out of five ambulatory adults with HFpEF are malnourished. Malnutrition was independently associated with adverse outcomes at 6 months. Future work is necessary to develop interventions that can address malnutrition.

Diuretics, SGLT2 inhibitors and falls in older heart failure patients: to prescribe or to deprescribe? A clinical review

PURPOSE

Both heart failure and its treatment with diuretics or SGLT2 inhibitors increase fall risk in older adults. Therefore, decisions to continue or deprescribe diuretics or SGLT2 inhibitors in older heart failure patients who have fallen are generally highly complex and challenging for clinicians. However, a comprehensive overview of information required for rationale and safe decision-making is lacking. The aim of this clinical review was to assist clinicians in safe (de)prescribing of these drug classes in older heart failure patients.

METHODS

We comprehensively searched and summarized published literature and international guidelines on the efficacy, fall-related safety issues, and deprescribing of the commonly prescribed diuretics and SGLT2 inhibitors in older adults.

RESULTS

Both diuretics and SGLT2 inhibitors potentially cause various fall-related adverse effects. Their fall-related side effect profiles partly overlap (e.g., tendency to cause hypotension), but there are also important differences; based on the currently available evidence of this relatively new drug class, SGLT2 inhibitors seem to have a favorable fall-related adverse effect profile compared to diuretics (e.g., low/absent tendency to cause hyperglycemia or electrolyte abnormalities, low risk of worsening chronic kidney disease). In addition, SGLT2 inhibitors have potential beneficial effects (e.g., disease-modifying effects in heart failure, renoprotective effects), whereas diuretic effects are merely symptomatic.

CONCLUSION

(De)prescribing diuretics and SGLT2 inhibitors in older heart failure patients who have fallen is often highly challenging, but this clinical review paper assists clinicians in individualized and patient-centered rational clinical decision-making: we provide a summary of available literature on efficacy and (subclass-specific) safety profiles of diuretics and SGLT2 inhibitors, and practical guidance on safe (de)prescribing of these drugs (e.g. a clinical decision tree for deprescribing diuretics in older adults who have fallen).

Physician Perspectives on the Use of Beta Blockers in Heart Failure With Preserved Ejection Fraction

β-blockers are commonly used in heart failure with preserved ejection fraction (HFpEF), even in the absence of a compelling indication and despite the potential to cause harm. Identifying reasons for β-blocker prescription in HFpEF could permit the development of strategies to reduce unnecessary use and potentially improve medication prescribing patterns in this vulnerable population. We administered an online survey regarding β-blocker prescribing behavior to physicians trained in internal medicine or geriatrics (noncardiology physicians) and to cardiologists at 2 large academic medical centers. The survey assessed the reasons for β-blocker initiation, agreement regarding initiation and/or continuation of β-blockers by another clinician, and deprescribing behavior. The response rate was 28.2% (n = 231). Among respondents, 68.2% reported initiating β-blockers in patients with HFpEF. The most common reason for initiating a β-blocker was for treatment of an atrial arrhythmia. Notably, 23.7% of physicians reported initiating a β-blocker without an evidence-based indication. When a β-blocker was considered not necessary, 40.1% of physicians reported they were rarely or never willing to deprescribe. The most common reason for not deprescribing a β-blocker when the physician felt that a β-blocker was unnecessary was the concern about interfering with another physicians' treatment plan (76.6%). In conclusion, a significant proportion of noncardiology physicians and cardiologists report prescribing β-blockers to patients with HFpEF, even when evidence-based indications are absent, and rarely deprescribe β-blockers in these scenarios.

Geriatric Domains in Patients with Heart Failure with Preserved Ejection Fraction

Because heart failure with preserved ejection fraction (HFpEF) is closely linked to aging processes and disproportionately affects older adults, consideration of geriatric domains is paramount to ensure high-quality care to older adults with HFpEF. Multimorbidity, polypharmacy, cognitive impairment, depressive symptoms, frailty, falls, and social isolation each have important implications on quality of life and clinical events including hospitalization and mortality. There are multiple strategies to screen for these conditions. This narrative review underscores the importance of screening for multiple geriatric conditions, integrating these conditions into decision making, and addressing these conditions when caring for older adults with HFpEF.

N-of-1 trials to facilitate evidence-based deprescribing: Rationale and case study

Deprescribing has emerged as an important aspect of patient-centred medication management but is vastly underutilized in clinical practice. The current narrative review will describe an innovative patient-centred approach to deprescribing-N-of-1 trials. N-of-1 trials involve multiple-period crossover design experiments conducted within individual patients. They enable patients to compare the effects of two or more treatments or, in the case of deprescribing N-of-1 trials, continuation with a current treatment versus no treatment or placebo. N-of-1 trials are distinct from traditional between-patient studies such as parallel-group or crossover designs which provide an average effect across a group of patients and obscure differences between individuals. By generating data on the effect of an intervention for the individual rather than the population, N-of-1 trials can promote therapeutic precision. N-of-1 trials are a particularly appealing strategy to inform deprescribing because they can generate individual-level evidence for deprescribing when evidence is uncertain, and can thus allay patient and physician concerns about discontinuing medications. To illustrate the use of deprescribing N-of-1 trials, we share a case example of an ongoing series of N-of-1 trials that compare maintenance versus deprescribing of beta-blockers in patients with heart failure with preserved ejection fraction. By providing quantifiable data on patient-reported outcomes, promoting personalized pharmacotherapy, and facilitating shared decision making, N-of-1 trials represent a potentially transformative strategy to address polypharmacy.

Attitudes of older adults and their carers towards de-prescribing: A systematic review

AIM

The aim of this systematic review is to explore the attitudes of older adults (≥65 years old) and their carers towards de-prescribing.

METHODS

We identified relevant studies from three databases; MEDLINE, CINAHL and Web of Science. Two reviewers (MS, SS) independently extracted data from each selected study using a standardised self-developed data extraction form. Main findings of the studies were summarised descriptively.

RESULTS

A total of 35 studies were included in the review. Of them, 19 were questionnaire studies, 11 semi-structured interviews, 4 focus groups and 1 study used the nominal group technique approach. Most older adults and their carers were willing to have medication de-prescribed if told to do so by a healthcare professional (HCP). Other factors that increased willingness to de-prescribing included; trust in the HCP, side effects and inconvenience from medications as well as the prospect of follow-up and monitoring during de-prescribing. In contrast, perceived effectiveness, unawareness of lack of benefit, negative expectations of ageing and fear were factors preventing de-prescribing.

CONCLUSION

De-prescribing is an important concept in older people given the harm associated with polypharmacy in this age group. Overall, older adults and their carers are willing to have medication de-prescribed if facilitated by their HCP. However, there remain a few barriers to de-prescribing which may need to be addressed in certain patients, through discussions between older adults/their carers and a HCP, to allow de-prescribing to be more effective.

Polypharmacy in Older Heart Failure Patients: a Multidisciplinary Approach

PURPOSE OF REVIEW

We provide a review of considerations when applying principles of optimal pharmacotherapy to older adults with heart failure (HF), an analysis on the pivotal clinical trials focusing on applicability to older adults, and multi-disciplinary strategies to optimize the health of HF patients with polypharmacy.

RECENT FINDINGS

Polypharmacy is very common among patients with HF, due to medications for both HF and non-HF comorbidities. Definitions of polypharmacy were not developed specifically for older adults with HF and may need to be modified in order to meaningfully describe medication burden and promote appropriate medical therapy. This is because clinical practice guidelines for multi-drug HF regimens have unique considerations, given that they improve outcomes and symptoms of HF. Adults older than 65 years are well represented in contemporary clinical trials for HF with preserved ejection fraction (HFpEF) and guideline directed medical therapy (GDMT) for HF with reduced ejection fraction (HFrEF). While these trials did not have significant heterogeneity in safety or efficacy across a broad age spectrum, some may have limited representation of adults ≥ 80 years old, the sickest older adults, or those with decreased functional status. There is also a lack of data on the safety and efficacy of deprescribing HF medications, and deprescription in otherwise stable patients may lead to clinical destabilization or disease progression. There is therefore innate tension between the well-studied benefits of optimized HF therapy for older adults that must be weighed against the risks of polypharmacy and many unknowns that still exist. Given the strong evidence that optimized HF therapies confer symptomatic and mortality benefits for older adults, it is clear that polypharmacy in this context can be appropriate. A shift in paradigm is therefore needed when evaluating polypharmacy in patients with HF. Instead of assuming all polypharmacy is "good" or "bad," we propose a concerted move, using a multidisciplinary approach, to focus on the "appropriateness" of specific medications, in order to optimize HF medical therapy. Clinicians of all specialties caring for complex older adults with HF must consider goals of care, functional status, and new evidence-based therapies, in order to optimize this polypharmacy for older adults.

Differences in Older Patients' Attitudes Toward Deprescribing at Contextual and Individual Level

Background

Deprescribing requires patients' involvement and taking patients' attitudes toward deprescribing into account. To understand the observed variation in these attitudes, the influence of contextual-level factors, such as country or healthcare setting, should be taken into account.

Methods

We conducted a systematic review of studies using the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire among older adults. We searched articles in Medline and Embase up to 30 June 2021. PRISMA guideline was used for the search process and reporting. We summarized the outcomes from the rPATD and compared attitudes at study population level between high or low-middle-income countries, global regions, and healthcare settings using ANOVA testing. Correlations of the rPATD outcomes with the mean age of the study populations were tested. Associations with the rPATD outcomes at individual patient level extracted from the included studies were summarized.

Results

Sixteen articles were included. Percentages of patients willing to stop medication were significantly lower in low-middle-income countries (<70% in Nepal and Malaysia) compared to high-income countries (>85% in USA, Australia, European countries). No significant differences were observed when results were compared by global region or by healthcare setting but a high willingness (>95%) was seen in the two studies conducted in an inpatient population. A higher mean age at study level was associated with a higher willingness to stop medication. At individual level, associations between patient characteristics, including demographics and education, and attitudes toward deprescribing showed inconsistent results.

Conclusion

Findings about attitudes toward deprescribing are influenced by contextual factors. Future research should pay more attention to the influence of the healthcare system and setting as well as the culture on patients' attitudes.

Polypharmacy in Older People With Heart Failure: Roles of the Geriatrician and Pharmacist

Heart failure (HF) is a common health condition that typically affects older adults. Many people with HF are cared for on an inpatient basis, by noncardiologists, such as acute medical physicians, geriatricians and other physicians. Treatment options for HF are ever increasing, and adherence to guidelines for prognostic therapy contributes to polypharmacy, which is very familiar to clinicians who care for older people. This article explores the recent trials in both HF with reduced ejection fraction and HF with preserved ejection fraction and the limitations of international guidance in their management with respect to older people. In addition, this article discusses the challenge of managing polypharmacy in those with advanced age, and the importance of involving a geriatrician and pharmacist in the HF multidisciplinary team to provide a holistic and person-centred approach to optimisation of HF therapies.
