Are all outcomes in chronic heart failure rated equally? An argument for a patient-centred approach to outcome assessment

The association between patient-reported outcomes (PROs) and patient participation in chronic care: A scoping review

OBJECTIVES

Patient-reported outcomes (PROs) are increasingly applied in chronic care due to their many functionalities and synergies with current healthcare policies. The participatory potential of PROs is especially emphasised in the Danish context. This review scrutinises the association between PRO and patient participation in chronic care.

METHODS

This scoping review adheres to PRISMA-ScR guidelines, and the synthesis is based on narrative and thematic analyses.

RESULTS

Eighty-four articles were deemed eligible. The association between PRO and patient participation regards seven themes: PRO development, response rates and patient burden, patient empowerment and self-management, display and quality of data, patient-clinician communication, shared decision-making, and organisational and attitudinal aspects. Lack of knowledge, actor attitudes, organisational setup, and technological infrastructure act as the main barriers.

CONCLUSION

The connection between PROs and patient participation is dialectic and unfolds in three phases-before, during, and after patient-clinician consultation. Knowledge regarding the last phase is particularly scarce. Henceforth, studies should address how to include a broader segment of patients, PROs participatory effects over time and PROs impact on patients' everyday lives.

PRACTICE IMPLICATIONS

The review provides knowledge concerning the association between PROs and patient participation to enhance future chronic care, research, and discussions in the area.

Temporal Trends and Factors Associated With the Inclusion of Patient-Reported Outcomes in Heart Failure Randomized Controlled Trials: A Systematic Review

Background

Patient‐reported outcomes (PROs) are important measures of treatment response in heart failure. We assessed temporal trends in and factors associated with inclusion of PROs in heart failure randomized controlled trials (RCTs).

Methods and Results

We searched MEDLINE, Embase, and CINAHL for studies published between January 2000 and July 2020 in journals with an impact factor ≥10. We assessed temporal trends using the Jonckheere‐Terpstra test and conducted multivariable logistic regression to explore trial characteristics associated with PRO inclusion. We assessed the quality of PRO reporting using the Consolidated Standards of Reporting Trials (CONSORT) PRO extension. Of 417 RCTs included, PROs were reported in 226 (54.2%; 95% CI, 49.3%–59.1%), with increased reporting between 2000 and 2020 (P<0.001). The odds of PRO inclusion were greater in RCTs that were published in recent years (adjusted odds ratio [aOR] per year, 1.08; 95% CI, 1.04–1.12; P<0.001), multicenter (aOR, 1.89; 95% CI, 1.03–3.46; P=0.040), medium‐sized (aOR, 2.35; 95% CI, 1.26–4.40; P=0.008), coordinated in Central and South America (aOR, 5.93; 95% CI, 1.14–30.97; P=0.035), and tested health service (aOR, 3.12; 95% CI, 1.49–6.55; P=0.003), device/surgical (aOR, 6.66; 95% CI, 3.15–14.05; P<0.001), or exercise (aOR, 4.66; 95% CI, 1.81–12.00; P=0.001) interventions. RCTs reported a median of 4 (interquartile interval , 3–6) of a possible of 11 CONSORT PRO items.

Conclusions

Just over half of all heart failure RCTs published in high impact factor journals between 2000 and 2020 included PROs, with increased inclusion of PROs over time. Trials that were large, tested pharmaceutical interventions, and coordinated in North America / Europe had lower adjusted odds of reporting PROs relative to other trials. The quality of PRO reporting was modest.

Problems with the outcome measures in randomized controlled trials of traditional Chinese medicine in treating chronic heart failure caused by coronary heart disease: a systematic review

BACKGROUND

Traditional Chinese medicine (TCM) has gained widespread application in treating chronic heart failure (CHF) secondary to coronary heart disease (CHD). However, the sound clinical evidence is still lacking. Corresponding clinical trials vary considerably in the outcome measures assessing the efficacy of TCM, some that showed the improvement of clinical symptoms are not universally acknowledged. Rational outcome measures are the key to evaluate efficacy and safety of each treatment and significant elements of a convincing clinical trial. We aimed to summarize and analyze outcome measures in randomized controlled trials (RCTs) of TCM in treating CHF caused by CHD, subsequently identify the present problems and try to put forward solutions.

METHODS

We systematically searched databases including Embase, PubMed, Cochrane Library, CBM, CNKI, VIP and Wanfang from inception to October 8, 2018, to identify eligible RCTs using TCM interventions for treating CHF patients caused by CHD. Cochrane Database of Systematic Reviews (CDSR) was searched to include Cochrane systematic reviews (CSRs) of CHF. Two authors independently assessed the risk of bias of the included RCTs according to the Cochrane Handbook. Outcome measures of each trial were extracted and analyzed those compared with the CSRs. We also evaluated the reporting quality of the outcome measures.

RESULTS

A total of 31 RCTs were included and the methodology quality of the studies was generally low. Outcome measures in these RCTs were mortality, rehospitalization, efficacy of cardiac function, left ventricular ejection fraction (LVEF), 6 min' walk distance (6MWD) and Brain natriuretic peptide (BNP), of which mortality and rehospitalization are clinical end points while the others are surrogate outcomes. The reporting rate of mortality and rehospitalization was 12.90% (4/31), the other included studies reported surrogate outcomes. As safety measure, 54.84% of the studies reported adverse drug reactions. Two trials were evaluated as high in reporting quality of outcomes and that of the other 29 studies was poor due to lack of necessary information for reporting.

CONCLUSIONS

The present RCTs of TCM in treating CHF secondary to CHD did not concentrate on the clinical end points of heart failure, which were generally small in size and short in duration. Moreover, these trials lacked adequate safety evaluation, had low quality in reporting outcomes and certain risk of bias in methodology. For objective assessment of the efficacy and safety of TCM in treating CHF secondary to CHD, future research should be rigorous designed, set end points as primary outcome measures and pay more attention to safety evaluation throughout the trial.

Health-Related Quality of Life in Older Adults With Acute Cardiovascular Disease Undergoing Early Mobilization

Background

Early mobilization (EM) is safe and feasible in older adults with acute cardiovascular disease (CVD) and may improve posthospitalization patient-centred outcomes. Our objective was to assess posthospitalization health-related quality of life (HRQOL) in older adults with acute CVD undergoing EM.

Methods

Patients aged ≥ 60 years with acute CVD undergoing EM at an academic tertiary centre in Montreal, Quebec were prospectively enrolled from January 2018 to January 2020. Functional status was measured using the validated Level of Function Mobility Scale. HRQOL was measured using the Short-Form 36 questionnaire at 1 and 12 months posthospitalization. The primary outcome was the questionnaire's physical component summary (PCS) score at 1 month posthospitalization.

Results

There were 147 patients included in the analysis (aged 75.0 ± 8.7 years; 44.6% female; 48.6% with ischemic heart disease). The mean 1-month PCS score was 34.7 ± 9.7, which was 11.5 points and 8.4 points lower compared to age-matched Canadian normative data for people ages 65-74 years and ≥ 75 years, respectively. The mean PCS score at 12 months (36.5 ± 9.2) and the mean mental component summary scores at 1 and 12 months (36.9 ± 11.1; 40.5 ± 11.5) were lower than those of the age-matched population (all P < 0.0001). In the multivariable analysis, increased age and worse prehospitalization function were associated with lower PCS score at 1 month.

Conclusions

Older adults with acute CVD had lower HRQOL at 1 and 12 months posthospitalization than age-matched Canadian norms. Prehospitalization functional status was predictive of poor posthospitalization HRQOL. The EM program was safe and feasible in this patient population. Further studies are needed to determine whether EM can improve posthospitalization patient-centred outcomes in older adults, particularly those with poor prehospitalization functional status.

Measuring the success of interventions for caregivers: a focussed systematic review

PURPOSE OF REVIEW

The selection and application of outcome measures are fundamental steps in the research process because they inform decisions around intervention efficacy. We aimed to describe the outcomes used in trials of supportive interventions for adult caregivers of people with three exemplar life-limiting conditions: heart failure, dementia or stroke.

RECENT FINDINGS

We performed a focussed review of 134 published trials that included interventions designed to improve caregivers' health and wellbeing and/or ability to function in their caring role. We extracted and categorized all caregiver outcomes described in the studies. We identified inconsistency in the outcomes measured; frequent use of bespoke and adapted tools (29% of outcomes were bespoke), and a lack of clarity in outcome priorities (the mean number of outcomes per trial was four [range: 1-11]). Outcome scales that purport to measure the psychological impact of the caring role were the most popular tools in all three caregiver groups.

SUMMARY

Outcomes used in trials related to adult caregivers are characterized by inconsistencies in outcome measure selection and assessment. This heterogeneity complicates comparisons of treatments and attempts to pool data.

Measuring patient outcomes in chronic heart failure: psychometric properties of the Care-Related Quality of Life survey for Chronic Heart Failure (CaReQoL CHF)

Background

The Care-Related Quality of Life survey for Chronic Heart Failure (CaReQoL CHF) is a newly developed patient-reported outcome measure (PROM) that measures care-related quality of life in patients diagnosed with chronic heart failure. This study describes the psychometric properties of the questionnaire and its relationship with disease severity and global rating of quality of care.

Method

Insurance companies selected patients with a recorded diagnosis of chronic heart failure and for whom the hospital submitted a billing statement in the last year. Exploratory factor analysis, Cronbach’s alpha and item-rest correlation were used to construct the CaReQoL CHF. Construct validity was assessed by examining the mean values of the CaReQoL CHF scales for the categories of the widely-used New York Heart Association (NYHA) functional classification and by correlating the global rating of quality of care with the CaReQoL CHF scales.

Results

One thousand eighteen patients with chronic heart failure filled out the CaReQoL CHF (RR: 35.7%). The CaReQoL CHF consists of 20 items and three scales: social and emotional problems, physical limitations, and being in safe hands. The mean scores of the three scales differed significantly for the NYHA categories, particularly for the social-emotional problems and physical limitation scales. The ‘being in safe hands’ scale showed a moderate positive correlation with the global rating of quality of care.

Conclusions

The CaReQoL CHF is a concise and valid PROM that matches patients’ priorities in healthcare. It adds a new element to existing quality of life questionnaires for patients with chronic heart failure, that is ‘being in safe hands’ scale. This scale is relevant for patients because they experience anxiety and tension about their condition. Future research should determine whether the CaReQoL CHF can help healthcare providers in daily practice to focus treatment on outcomes of care that are relevant to individual patients.

Reporting of patient-centred outcomes in heart failure trials: are patient preferences being ignored?

Older people often suffer from multiple diseases. Therefore, universal cross-disease outcomes (e.g. functional status, quality of life, overall survival) are more relevant than disease-specific outcomes, and a range of potential outcomes are needed for medical decision-making. To assess how patient-relevant outcomes have penetrated randomized controlled trials (RCTs), reporting of these outcomes was reviewed in heart failure trials that included patients with multimorbidity. We systematically reviewed RCTs (Jan 2011–June 2012) and evaluated reported outcomes. Heart failure was chosen as condition of interest as this is common among older patients with multimorbidity. The main outcome was the proportion of RCTs reporting all-cause mortality, all-cause hospital admission, and outcomes in four domains of health, i.e. functional, signs and symptoms, psychological, and social domains. Of the 106 included RCTs, 50 (47 %) reported all-cause mortality and cardiovascular mortality and 29 (27 %) reported all-cause hospitalization and cardiovascular hospitalization. Of all trials, 68 (64 %) measured outcomes in the functional domain, 80 (75 %) in the domain of signs and symptoms, 65 (61 %) in the psychological domain, and 59 (56 %) in the social domain. Disease-specific instruments were more often used than non-disease-specific instruments. This review shows increasing attention for more patient-relevant outcomes; this is promising and indicates more awareness of the importance of a variety of outcomes desirable for patients. However, patients’ individual goal attainments were universally absent. For continued progress in patient-centred care, efforts are needed to develop these outcomes, study their merits and pitfalls, and intensify their use in research.

The clinical course of health status and association with outcomes in patients hospitalized for heart failure: insights from ASCEND-HF

AIMS

A longitudinal and comprehensive analysis of health-related quality of life (HRQOL) was performed during hospitalization for heart failure (HF) or soon after discharge.

METHODS AND RESULTS

A post-hoc analysis was performed of the ASCEND-HF trial. The EuroQOL five dimensions questionnaire (EQ-5D) was administered to study participants at baseline, 24 h, discharge/day 10, and day 30. EQ-5D includes functional dimensions mapped to corresponding utility scores (i.e. 0 = death and 1 = perfect health), and a visual analogue scale (VAS) ranging from 0 (i.e. 'worst imaginable health state') to 100 (i.e. 'best imaginable health state'). The association between baseline and discharge EQ-5D measurements and subsequent clinical outcomes including death and rehospitalization were assessed using multivariable logistic regression and Cox proportional hazards regression. A total of 6943 patients (97%) had complete EQ-5D data at baseline. Mapped utility and VAS scores (mean ± SD) increased over time, respectively, from 0.56 ± 0.23 and 45 ± 22 at baseline to 0.67 ± 0.26 and 58 ± 22 at 24 h and to 0.79 ± 0.20 and 68 ± 22 at discharge, and remained stable at day 30. Lower mapped utility scores at baseline [odds ratio (OR) per 0.1 decrease in utility score 1.03, 95% confidence interval (CI) 1.00-1.06] and discharge (OR 1.10, 95% CI 1.05-1.15) and VAS scores at baseline (OR per 10 point decrease 1.05, 95% CI 1.01-1.09) were significantly associated with increased risk of 30-day all-cause death or HF rehospitalization.

CONCLUSIONS

Patients hospitalized for HF had severely impaired health status at baseline and, although this improved substantially during admission, health status remained abnormal at discharge.

Composite outcome measures in a pragmatic clinical trial of chronic heart failure management: A comparative assessment

BACKGROUND

A number of composite outcomes have been developed to capture the perspective of the patient, clinician and objective measures of health in assessing heart failure outcomes. To date there has been a limited examination in the composition of these outcomes.

METHODS AND RESULTS

Three commonly used scoring systems in heart failure trials: Packer's composite, Patient Journey and the African American Heart Failure Trial (A-HeFT) scores were compared in assessing outcomes from the Which heart failure intervention is most cost-effective & consumer friendly in reducing hospital care (WHICH(?)) Trial. Comparability and interpretability of these outcomes and the influence of each component to the final outcome were examined. Despite all three composite outcomes incorporating mortality, hospitalisation and quality of life (QoL), the contribution of each individual component to the final outcomes differed. The component with the most influence in deteriorating condition for the Packer's composite was hospitalisation (67.7%), while in Patient Journey it was QoL (61.5%) and for A-HeFT composite score it was mortality (45.4%).

CONCLUSIONS

The contribution made by each component varied in subtle, but important ways. This study emphasises the importance of understanding the value system of the composite outcomes to enable meaningful interpretation of results.

Lessons from community mental health to drive implementation in health care systems for people with long-term conditions

This paper aims to identify which lessons learned from the evidence and the experiences accruing from the transformation in mental health services in recent decades may have relevance for the future development of healthcare for people with long-term physical conditions. First, nine principles are discussed which we first identified to guide mental health service organisation, and all of which can be potentially applied to long term care as well (autonomy, continuity, effectiveness, accessibility, comprehensiveness, equity, accountability, co-ordination, and efficiency). Second, we have outlined innovative operational aspects of service user participation, many of which were first initiated and consolidated in the mental health field, and some of which are now also being implemented in long term care (including case management, and crisis plans). We conclude that long term conditions, whether mental or physical, deserve a long-term commitment from the relevant health services, and indeed where continuity and co-ordination are properly funded implemented, this can ensure that the symptomatic course is more stable, quality of life is enhanced, and the clinical outcomes are more favourable. Innovations such as self-management for long-term conditions (intended to promote autonomy and empowerment) need to be subjected to the same level of rigorous scientific scrutiny as any other treatment or service interventions.

Identifying outcomes of clinical genetic services: qualitative evidence and methodological considerations

Extensive research into the tangible and intangible implications of Clinical Genetic Services (CGSs) has confirmed the relevance of a multidimensional outcome of benefit conceptually linked to perceived control. This paper aims to report qualitative findings from one small study aiming to add to the evidence pool confirming the relevance of such an outcome to participants from one UK clinical genetics center. Data were collected using focus groups and individual interviews with 22 service users from the following conditions: Hereditary Breast and Ovarian Cancer (HBOC), von Hippel Lindau disorder (VHL), Duchenne and Becker muscular dystrophy (DBMD), cystic fibrosis (CF) and tuberous sclerosis (TS). Transcripts were analyzed using thematic analysis and four dimensions of benefit were identified relating to cognitive, behavioral, social and emotional consequences. These dimensions related to an overarching conceptual outcome described as Perceived Familial Control. Findings are discussed to illustrate the inter-generational and intra-generational familial dimensions of CGSs and reinforce the significance of a familial focus to any genetics-specific outcome measure. The prospect and methodological considerations of a familial composite outcome measure for measuring overall benefit of CGSs is discussed based on current and past findings.
