What services are currently provided to people with HFpEF in the UK and what are their components? A protocol for a scoping literature review.

AIM: Heart failure with preserved ejection fraction (HFpEF) is increasing in incidence and is increasingly the most common heart failure (HF) diagnosis. Patients with HFpEF are often excluded from specialist HF services which has negative impacts on their healthcare experiences and health-related outcomes. As emerging evidence-based treatments are being incorporated into clinical guidelines, it is timely to focus on the management of this phenotype. This review aims to explore literature around care provision for HFpEF in the United Kingdom; to characterise and assess HFpEF care pathways against current standards, and to generate evidence to create an optimised framework of care. METHODS & RESULTS: A scoping review of the evidence from six databases will be performed, alongside a search of grey literature search and consultation with relevant experts. Given expected heterogeneity, multiple lines of synthesis are anticipated. Data analysis will follow best practice guidelines for the synthesising methodologies selected. Patient and public representatives will assist with analysis and in identifying priority components for HFpEF clinical services. CONCLUSION: This scoping literature review will enable an in-depth examination of the current health service provision for those with HFpEF in the UK. Synthesis of key components of services and illumination of challenges and barriers will inform current and future practice. There is a long history of specialist HF care in the UK, including seminal work on nurse-led care. Therefore, evidence derived from this review will likely be useful to HF services across Europe. The proposed combination of the search across both peer-reviewed literature and grey literature, combined with patient and public involvement will identify the key components of a framework of care for those with HFpEF.

Development steps of multimodal exercise interventions for older adults with multimorbidity: A systematic review.

Background and Aims: Multicomponent exercise interventions are recommended for older adults and for those with chronic diseases. While multiple programs have been tested, no one has yet explored how these programs were developed. This review set out to determine what development steps multicomponent exercise intervention studies that include older adults with multimorbidity have taken. Methods: Systematic review and narrative synthesis. Results: One hundred and thirty-eight studies meeting review criteria (Population: adults ≥60 years with multimorbidity; Intervention: exercise interventions with ≥2 components; Comparator: any considered; Outcome: any considered) were retrieved. Most studies (70%) do not report intervention development actions as suggested by available guidance. Notable deviations from recommendations include limited performance of systematic review of previously published evidence, lack of engagement with theory, and few examples of design then refine. Conclusions: Exercise interventions for older adults with multimorbidity do not appear to follow best practice in terms of their developing. Disregard of development recommendations risks contributing to research redundancy and/or avoidable waste, as important steps that make sure the intervention is warranted, suitable for the population in question, and tested using optimal methods and outcome measures are overlooked.

The use of the World Guidelines for Falls Prevention and Management's risk stratification algorithm in predicting falls in The Irish Longitudinal Study on Ageing (TILDA).

BACKGROUND: the aim of this study was to retrospectively operationalise the World Guidelines for Falls Prevention and Management (WGFPM) falls risk stratification algorithm using data from The Irish Longitudinal Study on Ageing (TILDA). We described how easy the algorithm was to operationalise in TILDA and determined its utility in predicting falls in this population. METHODS: participants aged ≥50 years were stratified as 'low risk', 'intermediate' or 'high risk' as per WGFPM stratification based on their Wave 1 TILDA assessments. Groups were compared for number of falls, number of people who experienced one or more falls and number of people who experienced an injury when falling between Wave 1 and Wave 2 (approximately 2 years). RESULTS: 5,882 participants were included in the study; 4,521, 42 and 1,309 were classified as low, intermediate and high risk, respectively, and 10 participants could not be categorised due to missing data. At Wave 2, 17.4%, 43.8% and 40.5% of low-, intermediate- and high-risk groups reported having fallen, and 7.1%, 18.8% and 18.7%, respectively, reported having sustained an injury from falling. CONCLUSION: the implementation of the WGFPM risk assessment algorithm was feasible in TILDA and successfully differentiated those at greater risk of falling. The high number of participants classified in the low-risk group and lack of differences between the intermediate and high-risk groups may be related to the non-clinical nature of the TILDA sample, and further study in other samples is warranted.

A critical interpretive synthesis of the lived experiences and health and patient-reported outcomes of people living with COPD who isolated during the COVID-19 pandemic.

AIMS: To determine the lived experiences of people with COPD who isolated at home during the coronavirus disease 2019 (COVID-19) pandemic, and explore how these experiences affected health and patient-reported outcomes. METHODS: Keyword searches were performed in five bibliographic databases. Critical interpretative synthesis (CIS) methods were used to interrogate and understand patterns across studies. RESULTS: 23 studies were identified; three employed qualitative methods and 20 quantitative methods. Application of CIS methods highlighted a core synthetic concept that appeared to underpin experiences and outcomes, that of a heightened perception of risk. Using the Risk Perception Model as a framework, we found that cognitive factors such as knowledge of underlying health status and the transmissibility of COVID-19; experiential factors including previous episodes of breathlessness and hospitalisation; and sociocultural factors such as access to trusted sources of information, influenced perceptions of risk. In turn, this influenced behaviour, which translated to outcomes such as reduced hospitalisations, deconditioning and social isolation as people avoided "high-risk" situations and settings. CONCLUSIONS: Patients with COPD who isolated at home during the COVID-19 pandemic had a heightened perception of risk which was influenced by cognitive, experiential and sociocultural factors. The consequences of this were varied and included both positive (reduced exacerbations and hospitalisations) and negative (social isolation, deconditioning, diminished capacity for self-care) outcomes. Understanding risk and the impacts it can have could help clinicians to support people with COPD return to their pre-pandemic way of living and enable better communication of ongoing risk from respiratory viral illness.

Eight-year longitudinal falls trajectories and associations with modifiable risk factors: evidence from The Irish Longitudinal Study on Ageing (TILDA).

BACKGROUND: The label 'faller' and the associated stigma may reduce healthcare-seeking behaviours. However, falls are not inevitably progressive and many drivers are modifiable. This observational study described the 8-year longitudinal trajectories of self-reported falls in The Irish Longitudinal Study on Ageing (TILDA) and studied associations with factors, including mobility, cognition, orthostatic hypotension (OH), fear of falling (FOF) and use of antihypertensive and antidepressant medications. METHODS: Participants aged ≥50 years at each wave were categorised by whether they averaged ≥2 falls in the previous year (recurrent fallers) or not (≤1 fall). Next-wave transition probabilities were estimated with multi-state models. RESULTS: 8,157 (54.2% female) participants were included, of whom 586 reported ≥2 falls at Wave 1. Those reporting ≥2 falls in the past year had a 63% probability of moving to the more favourable state of ≤1 fall. Those reporting ≤1 fall had a 2% probability of transitioning to ≥2 falls. Besides older age and higher number of chronic conditions, factors that increased the risk of transitioning from ≤1 fall to ≥2 falls were lower Montreal Cognitive Assessment score, FOF and taking antidepressants. Conversely, male sex, higher timed up and go time, the presence of OH and being on antidepressants reduced the probability of improving from ≥2 falls to ≤1 fall. CONCLUSION: The majority of recurrent fallers experienced favourable transitions. Improvements in cognitive and psychological status, psychotropic prescribing, mobility and OH may help improve trajectories. Findings may help combat stigma associated with falling and promote preventative healthcare-seeking behaviours.

What are the outcomes of dietary interventions in Heart Failure with preserved Ejection Fraction? A systematic review and meta-analysis.

AIMS: To determine the efficacy of dietary interventions in Heart Failure with preserved Ejection Fraction (HFpEF). METHOD AND RESULTS: Keyword searches were performed in five bibliographic databases to identify randomized or controlled studies of dietary interventions conducted in HFpEF or mixed heart failure (HF) samples published in the English language. Studies were appraised for bias and synthesized into seven categories based on the similarity of the intervention or targeted population. The quality of the body of evidence was assessed via the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) framework. Twenty-five unique interventions were identified; 17 were considered for meta-analysis. Most studies were judged to be at high risk of bias. There was moderate-quality evidence that caloric restriction led to clinically meaningful improvements in blood pressure and body weight. There was moderate-quality evidence that carbohydrate restriction resulted in meaningful reductions in blood pressure. There was very low-quality evidence that protein supplementation improved blood pressure and body weight and moderate-quality evidence for clinically meaningful improvements in function. CONCLUSIONS: While some types of dietary interventions appeared to deliver clinically meaningful change in critical outcomes; the study heterogeneity and overall quality of the evidence make it difficult to make firm recommendations. Greater transparency when reporting the nutritional composition of interventions would enhance the ability to pool studies. REGISTRATION: PROSPERO CRD42019145388.

What dietary interventions have been tested in heart failure with preserved ejection fraction? A systematic scoping review.

AIMS: To determine what dietary interventions have been tested in heart failure with preserved ejection fraction (HFpEF), the modulation method, and outcomes employed and to summarize any evidence for benefit. METHODS AND RESULTS: We performed key word searches in five bibliographic databases from 2001 to 2021, to identify randomized or experimental dietary interventions tested in HFpEF or mixed heart failure (HF) samples. Study characteristics were summarized according to population, intervention, comparator, outcome categories and intervention complexity was assessed. Twenty-five clinical investigations were retrieved; only 10 (40%) were conducted exclusively in HFpEF; the remainder enrolled mixed HF samples. Most studies employed either highly tailored prescribed diets (n = 12, 48%) or dietary supplementation (n = 10, 40%) modalities. Dietary pattern interventions (n = 3, 12%) are less well represented in the literature. CONCLUSION: Heterogeneity made pooling studies challenging. Better reporting of baseline characteristics and the use of standardized HF lexicon would ensure greater confidence in interpretation of studies involving mixed HF populations. The field would benefit greatly from explicit reporting of the biological mechanism of action (e.g. the causal pathway) that an intervention is designed to modulate so that studies can be synthesized via their underlying mechanism of action by which diet may affect HF. An extension of the current set of core outcomes proposed by the European Society of Cardiology Heart Failure Association would ensure dietary clinical endpoints are more consistently defined and measured.

'Keeping the plates spinning': a qualitative study of the complexity, barriers, and facilitators to caregiving in heart failure with preserved ejection fraction.

AIMS: Heart failure with preserved ejection fraction (HFpEF) accounts for 50% of all heart failure cases; yet remains poorly understood, diagnosed, and managed, which adds complexity to the carer role. No study to date has investigated the experiences of informal carers of people with HFpEF. The aim of this study was to explore the role and experiences of informal carers of people with HFpEF. METHODS AND RESULTS: A qualitative study using semi-structured interviews involving carers alone, patients alone, or carer/patient dyads. The interviews were part of a larger programme of research in HFpEF. Participants were recruited from three regions of England. Interviews were recorded, transcribed verbatim, and analysed thematically. Twenty-two interviews were conducted with 38 participants, 17 were informal carers. Three inter-related themes were identified: Theme 1, the complex nature of informal caregiving ('spinning plates'); Theme 2, the barriers to caregiving ('the spinning falters'); and Theme 3, the facilitators of caregiving ('keeping the plates spinning'). CONCLUSIONS: Informal carers play an important role in supporting people with HFpEF. The experience of caregiving in HFpEF is similar to that described for Heart Failure with reduced Ejection Fraction, but complicated by challenges of limited information and support specific to HFpEF, and high burden of multi-morbidity. Healthcare providers should assess the needs of informal carers as part of patient care in HFpEF. Carers and patients would benefit from improved information and co-ordinated management of HFpEF and multi-morbidities. Helping carers 'keep the plates spinning' will require innovative approaches and co-ordination across the care continuum.

Cumulative complexity: a qualitative analysis of patients' experiences of living with heart failure with preserved ejection fraction.

AIMS: To investigate how heart failure with preserved ejection fraction (HFpEF), within the context of limited clinical services, impacts patients' lives. METHODS AND RESULTS: Secondary thematic analysis informed by the cumulative complexity model (CCM), of interview transcripts from 77 people diagnosed with HFpEF and their carers. Four themes corresponding to the core concepts of workload, capacity, access, and outcome described in the CCM were generated. Theme 1: Shouldering a heavy workload described the many tasks expected of people living with HFpEF. Theme 2: The multiple threats to capacity described how patients and carers strived to engage with this work, but were often faced with multiple threats such as symptoms and mobility limitations. Deficient illness identity (Theme 3) reflects how HFpEF either was not recognized or was perceived as a more benign form of HF and therefore afforded less importance or priority. These themes contributed to a range of negative physical, social, and psychological outcomes and the perception of loss of control described in Theme 4: Spiraling complexity. CONCLUSIONS: The constellation of HFpEF, multi-morbidity, and ageing creates many demands that people with HFpEF are expected to manage. Concurrently, the same syndromes threaten their ability to physically enact this work. Patients' recollections of their interactions with health professionals suggest that there is a widespread misunderstanding of HFpEF, which can prohibit access to care that could potentially reduce or prevent deterioration.

Clinical and demographic correlates of accelerometer-measured physical activity in participants enrolled in the OPTIMISE HFpEF study.

AIMS: This study aimed to measure physical activity (PA) in participants with suspected heart failure with preserved ejection fraction (HFpEF) and assess associations between PA and participant characteristics. METHODS AND RESULTS: Adults with presumed HFpEF were recruited and received diagnostic evaluation and clinical assessment. Physical activity was objectively measured using accelerometers over 7 days. To examine predictors of PA, a best subset analysis was used, with the optimal model defined as that with the lowest Bayesian information criterion. One hundred and twenty-four participants with presumed HFpEF who had valid accelerometer data were included in this study. Seventy-six were confirmed by a cardiologist as meeting the European Society of Cardiology diagnosis criteria for HFpEF. The median age of all participants was 80.1 years, and 47.4% were female. Patients spent most of each 24-h period at low-intensity PA and few or no durations at high-intensity PA, with lower activity for those with HFpEF. Gait speed was the best univariate correlate of activity levels (adjusted R2 0.29). The optimal model using best subsets regression included six variables and improved adjusted R2 to 0.47. In the model, lower levels of PA were associated with slower gait speed, lower levels of anxiety, higher levels of depression, past smoking history, a confirmed HFpEF diagnosis, and higher body mass index. CONCLUSION: Participants demonstrated very low PA levels. The study has identified important patient characteristics associated with PA, which may help to identify those most in need of interventions. Notably, participants with confirmed HFpEF were more inactive than participants with other heart failure phenotypes.

Characteristics of patients with heart failure with preserved ejection fraction in primary care: a cross-sectional analysis.

BACKGROUND: Many patients with heart failure with preserved ejection fraction (HFpEF) are undiagnosed, and UK general practice registers do not typically record heart failure (HF) subtype. Improvements in management of HFpEF is dependent on improved identification and characterisation of patients in primary care. AIM: To describe a cohort of patients recruited from primary care with suspected HFpEF and compare patients in whom HFpEF was confirmed and refuted. DESIGN & SETTING: Baseline data from a longitudinal cohort study of patients with suspected HFpEF recruited from primary care in two areas of England. METHOD: A screening algorithm and review were used to find patients on HF registers without a record of reduced ejection fraction (EF). Baseline evaluation included cardiac, mental and physical function, clinical characteristics, and patient reported outcomes. Confirmation of HFpEF was clinically adjudicated by a cardiologist. RESULTS: In total, 93 (61%) of 152 patients were confirmed HFpEF. The mean age of patients with HFpEF was 79 years, 46% were female, 80% had hypertension, and 37% took ≥10 medications. Patients with HFpEF were more likely to be obese, pre-frail or frail, report more dyspnoea and fatigue, were more functionally impaired, and less active than patients in whom HFpEF was refuted. Few had attended cardiac rehabilitation. CONCLUSION: Patients with confirmed HFpEF had frequent multimorbidity, functional impairment, frailty, and polypharmacy. Although comorbid conditions were similar between people with and without HFpEF, the former had more obesity, symptoms, and worse physical function. These findings highlight the potential to optimise wellbeing through comorbidity management, medication rationalisation, rehabilitation, and supported self-management.

Clinicians' and patients' experiences of managing heart failure during the COVID-19 pandemic: a qualitative study.

BACKGROUND: Severe acute respiratory coronavirus 2 (SARS-CoV-2), also known as coronavirus disease 2019 (COVID-19), resulted in unprecedented societal and healthcare provision change, which has been implemented at pace. Little is known about the indirect impacts of these changes and what the future effects may be. AIM: To explore patients' and clinicians' experiences of managing heart failure (HF) during the COVID-19 pandemic. DESIGN & SETTING: Qualitative study in three regions of the UK: Cambridgeshire, Greater Manchester, and the West Midlands. METHOD: Semi-structured interviews (n = 30) were conducted with older adults with established HF and healthcare providers from primary and secondary health services involved in their care. Interviews were analysed thematically. RESULTS: Compliance with the government guidance 'Stay at home, protect the NHS, and save lives' during the COVID-19 pandemic, and perceptions relating to risk from COVID-19 and underlying morbidity, drove 'being careful' behaviours and organisational changes. Enacting behavioural change and implementing organisational change resulted in opportunities and challenges for health and healthcare practice. CONCLUSION: Perception of risk led to significant behavioural and organisational change during the pandemic. Some changes described by both patients and clinicians, such as enhanced relationships and self-monitoring, present as opportunities, and consideration should be given as to how to maintain or develop these. Equally, indirect impacts of COVID-19 and the associated lockdown, such as disengagement and withdrawal, and the fallout from reluctance to access health services, should be acknowledged and interventions to address these challenges are needed.
