Development of a supportive care measure for economic evaluation of end-of-life care using qualitative methods

The Use of a Comprehensive Concept of Capability for Wellbeing Assessment: A Best-Fit Framework Synthesis

Developing an instrument with the capability approach can be challenging, since the capability concept of Sen is ambiguous concerning the burdens that people experience whilst achieving their capabilities. A solution is to develop instruments with a comprehensive concept of capability, such as the concept of 'option-freedom'. This study aims to develop a theoretical framework for instrument development with the concept of option-freedom. A best-fit framework synthesis was conducted with seven qualitative papers by one researcher. Two researchers supported the synthesis by discussing interim results during the synthesis. A priori concepts of option-freedom were used to deductively code against. Themes and subthemes were developed inductively when data did not match a priori themes. Seven paper were identified that fulfilled the eligibility criteria. Four themes emerged from the synthesis. (1) Option Wellbeing represents a range of options that need to be satisfied for individuals to experience wellbeing. (2) Self-Realization represents that there are experiences in an individual's life that have value beyond realizing options. (3) Perceived Access to Options represents the perceived ability of individuals to realize freedoms. (4) Perceived Control represents the experience of having control. Developing an instrument with the proposed framework has two benefits. First, it acknowledges the importance of assessing impediments in realizing capabilities for wellbeing assessment. Secondly, the themes form a broad informational base by including themes related to subjective wellbeing. Future research should study the feasibility of implementing the framework for instrument development.

A more equitable approach to economic evaluation: Directly developing conceptual capability wellbeing attributes for Tanzania and Malawi

Capability wellbeing can potentially provide a holistic outcome for health economic evaluation and the capability approach seems promising for African countries. As yet there is no work that has explored the evaluative space needed for health and care decision making at the whole population level and procedures that merely translate existing measures developed in the global north to contexts in the global south risk embedding structural inequalities. This work seeks to elicit the concepts within the capability wellbeing evaluative space for general adult populations in Tanzania and Malawi. Semi-structured interviews with 68 participants across Tanzania and Malawi were conducted between October 2021 and July 2022. Analysis used thematic coding frames and the writing of analytic accounts. Interview schedules were common across the two country settings, however data collection and analysis were conducted independently by two separate teams and only brought together once it was clear that the data from the two countries was sufficiently aligned for a single analysis. Eight common attributes of capability wellbeing were found across the two countries: financial security; basic needs; achievement and personal development; attachment, love and friendship; participation in community activities; faith and spirituality; health; making decisions without unwanted interference. These attributes can be used to generate outcome measures for use in economic evaluations comparing alternative health interventions. By centring the voices of Tanzanians and Malawians in the construction of attributes that describe a good life, the research can facilitate greater equity within economic evaluations across different global settings.

Homecare amyotrophic lateral sclerosis (ALS): A multidisciplinary, home-based model of care for patients with ALS and their caregivers

INTRODUCTION/AIMS

Multidisciplinary care for patients with amyotrophic lateral sclerosis (ALS) is recommended in international guidelines, but reaches its limits when immobility increases. This pilot project addresses this gap by delivering home-based, specialized, multiprofessional support to ALS patients who are not able to attend outpatient care. The study assessed the feasibility of this model of care and the satisfaction of both patients and caregivers.

METHODS

This was a longitudinal cohort study of patients with ALS and their caregivers in the surroundings of Munich, Germany. Patients were regularly visited at home by a multiprofessional team (neurologists/palliative care physicians, nurse, social worker, chaplain).

RESULTS

A total of 94 patients with ALS were included in the homecare project and 88 patients and 74 caregivers were enrolled in the accompanying study. The mean care duration was 221 days, enabling 61% of the 49 deceased patients to die at home. Notably, 20% of patients chose a way to hasten death. Patient satisfaction (ICECAP Supportive Care Measure [SCM]: 23.7/28, CollaboRATE: 10.6/12) and caregiver perception of the end-of-life phase (Caregiver Evaluation of the Quality of End-Of-Life Care [CEQUEL]: 24.9/26) were high.

DISCUSSION

This pilot project successfully implemented specialized, home-based multidisciplinary care for ALS patients and caregivers, demonstrating both feasibility and high satisfaction. The program enabled a large proportion of patients to remain in their homes, reducing the need for hospital care. The multiprofessional approach, including neuropalliative, psychosocial and spiritual support provided comprehensive care that addressed needs of patients and caregivers. Further research is warranted to explore cost-effectiveness.

From Health to Well-Being: Toward a Monetary Valuation of a Well-Being-Adjusted Life-Year

OBJECTIVES

Economic evaluations using broader measures to capture benefits beyond improved health can inform policy making, but only if the monetary value of gains measured using these instruments is understood. This study explored contingent valuation as a method to estimate the monetary value of a well-being-adjusted life-year (WALY) as measured by ICEpop Capability Measure for Adults (ICECAP-A).

METHODS

In a large online survey of representative samples from 7 European countries, participants valued a change in the ICECAP-A from their current health state to a randomly assigned hypothetical state. Participants were instructed that an unspecified treatment could avoid a loss or produce a gain in well-being and were asked for their willingness to pay (WTP) for this treatment. WTP per WALY was calculated using an aggregated approach that used ICECAP-A tariffs from the United Kingdom.

RESULTS

We analyzed a sample of 7428 observations, focusing on avoided losses (n = 6002) because the results for gains were not theoretically valid. Different cutoff points for a marginal change were explored. Depending on the definition of a marginal change, WTP per WALY averaged between €13 323.28 and €61 375.63 for avoided losses between [0, 0.5] and [0, 0.1], respectively, for 1 month. Mean WTP per WALY varied across the countries as follows: Denmark (€17 867.93-€88 634.14), France (€10 278.35-€45 581.28), Germany (€12 119.39-€54 566.56), Italy (€11 753.69-€52 161.25), The Netherlands (€14 612.88-€58 951.74), Spain (€11 904.12-€57 909.17), and United Kingdom (€13 133.75-€68 455.85).

CONCLUSION

Despite the inherent limitations of our study, it offers valuable insights into methods for eliciting the WTP for changes in capability well-being as measured with ICECAP-A.

What Aspects of Quality of Life are Important from Palliative Care Patients' Perspectives? A Framework Analysis to Inform Preference-Based Measures for Palliative and End-of-Life Settings

BACKGROUND AND OBJECTIVE

Preference-based outcome measures are commonly applied in economic analyses to inform healthcare resource allocation decisions. Few preference-based outcome measures have been specifically developed for palliative and end-of-life settings. This study aimed to identify which quality-of-life domains are most important to Australians receiving specialised palliative care services to help determine if the development of a new condition-specific preference-based outcome measure is warranted.

METHODS

In-depth face-to-face interviews were conducted with 18 participants recruited from palliative care services in South Australia. Data were analysed using a framework analysis drawing on findings from a systematic review of international qualitative studies investigating the quality-of-life preferences of patients receiving palliation (domains identified included cognitive, emotional, healthcare, personal autonomy, physical, preparatory, social, spiritual). Participants identified missing or irrelevant domains in the EQ-5D and QLU-C10D questionnaires and ranked the importance of domains.

RESULTS

A priori domains were refined into cognitive, environmental, financial, independence, physical, psychological, social and spiritual. The confirmation of the eight important quality-of-life domains across multiple international studies suggests there is a relatively high degree of convergence on the perspectives of patients in different countries. Four domains derived from the interviews are not covered by the EQ-5D and QLU-C10D (cognitive, environmental, financial, spiritual), including one of the most important (spiritual).

CONCLUSIONS

Existing, popular, preference-based outcome measures such as the EQ-5D do not incorporate the most important, patient-valued, quality-of-life domains in the palliative and end-of-life settings. Development of a new, more relevant and comprehensive preference-based outcome measure could improve the allocation of resources to patient-valued services and have wide applicability internationally.

Methodological challenges and potential solutions for economic evaluations of palliative and end-of-life care: A systematic review

BACKGROUND

Given the increasing demand for palliative and end-of-life care, along with the introduction of costly new treatments, there is a pressing need for robust evidence on value. However, comprehensive guidance is missing on methods for conducting economic evaluations in this field.

AIM

To identify and summarise existing information on methodological challenges and potential solutions/recommendations for economic evaluations of palliative and end-of-life care.

DESIGN

We conducted a systematic review of publications on methodological considerations for economic evaluations of adult palliative and end-of-life care as per our PROSPERO protocol CRD42020148160. Following initial searches, we conducted a two-stage screening process and quality appraisal. Information was thematically synthesised, coded, categorised into common themes and aligned with the items specified in the Consolidated Health Economic Evaluation Reporting Standards statement.

DATA SOURCES

The databases Medline, Embase, HTADatabase, NHSEED and grey literature were searched between 1 January 1999 and 5 June 2023.

RESULTS

Out of the initial 6502 studies, 81 were deemed eligible. Identified challenges could be grouped into nine themes: ambiguous and inaccurate patient identification, restricted generalisability due to poor geographic transferability of evidence, narrow costing perspective applied, difficulties defining comparators, consequences of applied time horizon, ambiguity in the selection of outcomes, challenged outcome measurement, non-standardised measurement and valuation of costs as well as challenges regarding a reliable preference-based outcome valuation.

CONCLUSION

Our review offers a comprehensive context-specific overview of methodological considerations for economic evaluations of palliative and end-of-life care. It also identifies the main knowledge gaps to help prioritise future methodological research specifically for this field.

Economic evaluation of dialysis and comprehensive conservative care for chronic kidney disease using the ICECAP-O and EQ-5D-5L; a comparison of evaluation instruments

BACKGROUND

Chronic Kidney Disease (CKD) patients often require long-term care, and while Hemodialysis (HD) is the standard treatment, Comprehensive Conservative Care (CCC) is gaining popularity as an alternative. Economic evaluations comparing their cost-effectiveness are crucial. This study aims to perform a cost-utility analysis comparing HD and CCC using the EQ-5D-5L and ICECAP-O instruments to assessing healthcare interventions in CKD patients.

METHODS

This short-term economic evaluation involved 183 participants (105 HD, 76 CCC) and collected data on demographics, comorbidities, laboratory results, treatment costs, and HRQoL measured by ICECAP-O and EQ-5D-5L. Incremental Cost-Effectiveness Ratios (ICERs) and Net Monetary Benefit (NMB) were calculated separately for each instrument, and Probabilistic Sensitivity Analysis (PSA) assessed uncertainty.

RESULTS

CCC demonstrated significantly lower costs (mean difference $8,544.52) compared to HD. Both EQ-5D-5L and ICECAP-O indicated higher Quality-Adjusted Life Years (QALYs) for both groups, but the difference was not statistically significant (p > 0.05). CCC dominated HD in terms of HRQoL measures, with ICERs of -$141,742.67 (EQ-5D-5L) and -$4,272.26 (ICECAP-O). NMB was positive for CCC and negative for HD, highlighting its economic feasibility.

CONCLUSION

CCC proves a preferable and more cost-effective treatment option than HD for CKD patients aged 65 and above, regardless of the quality-of-life measure used for QALY calculations. Both EQ-5D-5L and ICECAP-O showed similar results in cost-utility analysis.

A new sexual wellbeing paradigm grounded in capability approach concepts of human flourishing and social justice

Over the last twenty years, there has been a growing interest in measuring sexual wellbeing, including by a WHO/UNFPA working group in 2007, which sought clarity on key dimensions and asked for indicators of these to be devised. However, there remains a lack of conceptual clarity surrounding the concept of sexual wellbeing, which may create variation in what is being assessed and to what we are referring. This paper proposes one way in which to achieve conceptual clarity might be through the utilisation of a Capability Approach, thereby posing a new set of normative questions about what sexual wellbeing is. The central argument in this paper is for researchers, theorists and practitioners to focus more fully on a person's freedom to achieve sexual wellbeing within a particular social and cultural context. We suggest the kinds of data that might need to be captured to operationalise and measure such an understanding. By offering new critical insights, we hope to drive forward empirical and methodological development in the evaluation of sexual wellbeing.

ITV-Pal programme: protocol of evaluation of the implementation of tech-volunteer programme in palliative care services

INTRODUCTION

Volunteer support for patients and families at the end of life provides many benefits for the beneficiaries. New technologies could be a necessary resource in the accompaniment although, if there is little literature on palliative care volunteering in general, specifically on volunteering and new technologies, we find little information on the subject.Therefore, the aim of this study is to implement and evaluate a training program for palliative care volunteers using new technologies in order to begin accompanying patients and families in hospital or at home.

METHODS AND ANALYSIS

A mixed-method study design will be conducted. We will recruit 20 volunteers and 70 patients in two years.

INTERVENTION

training of volunteers in new technologies and volunteer accompaniment of patients/relatives using technologies. The control group will accompany patients as usual.

ETHICS AND DISSEMINATION

Ethics approval for the ITV-Pal Programme project was granted by the Malaga Regional Research Ethics Committee. As new knowledge is gained from this project, findings will be disseminated through publications, presentations and feedback to clinicians who are participating in this study.

Measurement properties of the EQ-5D in populations with a mean age of ≥ 75 years: a systematic review

PURPOSE

Healthcare interventions for middle-old and oldest-old individuals are often (economically) evaluated using the EQ-5D to measure health-related quality of life (HrQoL). This requires sufficient measurement properties of the EQ-5D. Therefore, the current study aimed to systematically review studies assessing the measurement properties of the EQ-5D in this population.

METHODS

The databases PubMed, Cochrane library, Web of Science, Embase, and EconLit were searched for studies providing empirical evidence of reliability, validity, and/or responsiveness of the EQ-5D-3L and EQ-5D-5L in samples with a mean age ≥ 75 years. Studies were selected by two independent reviewers, and the methodological quality was assessed using the COSMIN Risk of Bias checklist. Results were rated against updated criteria for good measurement properties (sufficient, insufficient, inconsistent, indeterminate). The evidence was summarized, and the quality of evidence was graded using a modified GRADE approach.

RESULTS

For both EQ-5D versions, high-quality evidence for sufficient convergent validity was found. Known-groups validity was sufficient for the EQ-5D-5L (high-quality evidence), whereas the results were inconsistent for the EQ-5D-3L. Results regarding the reliability were inconsistent (EQ-5D-3L) or entirely lacking (EQ-5D-5L). Responsiveness based on correlations of change scores with instruments measuring related/similar constructs was insufficient for the EQ-5D-3L (high-quality evidence). For the EQ-5D-5L, the available evidence on responsiveness to change in (Hr)QoL instruments was limited.

CONCLUSION

Since the responsiveness of the EQ-5D in a population of middle-old and oldest-old individuals was questionable, either using additional instruments or considering the use of an alternative, more comprehensive instrument of (Hr)QoL might be advisable, especially for economic evaluations.

Attributes development for a discrete choice experiment on preferences in sexual and reproductive health services for adolescents and young people in Nigeria

BACKGROUND

A major component of the validity of the discrete choice experiment (DCE) research design lies in the correct specification of attributes and levels relevant to the research focus. In this paper, we set out the validation steps we took in designing the tool for a DCE on preferences in sexual and reproductive health (SRH) services for adolescents and young people.

METHODOLOGY

This study was carried out among adolescents and young people (AYP) in Ogun State, Southwest Nigeria. We used a three-step mixed-methods process in developing the attributes and attribute-levels for our DCE tool. The first was to conduct a series of 16 focus group discussions (FGD) with AYP ensuring maximal variation (by age group, sex, marital status, and location). The FGD included a priority listing process in which participants were asked to list and rank the most important characteristics of optimal SRH services for AYP. The lists were harmonized and items were scored. The main (highest scoring) themes emerging from the harmonized priority list were converted into an initial set of attributes and the subthemes as level. These initial attributes and levels were presented to a panel of methods and content experts in a virtual modified Delphi process. This was for deciding on the importance of the attributes in providing optimum sexual and reproductive health services for young people, and the appropriateness of the levels. The same set of attributes was presented to another set of AYP in a series of four FGD to clarify meanings, and test whether the wordings were well understood. We applied some decision rules for including and excluding attributes and levels in the different phases of the development process.

RESULTS

We extracted an initial set of nine attributes with 2-4 levels each from the first FGD sessions. These were revised to a final set of seven attributes with 2-4 levels each based on findings from the expert review and final validation FGDs with AYP. The final attributes were: the type of staff, physical environment, health worker attitude, cost, waiting time, contraceptive availability, and opening hours.

CONCLUSION

The final set of attributes covered those relating to the services provided, the health workers providing the services, and the AYP. Our three-step process which included both quantitative and qualitative approaches ensured a rigorous process that produced a reliable combination of attributes and levels. Although we had to trade off some competing attributes to come to a final list, our decision rules helped us to conduct a transparent and reproducible process.

A think-aloud study of the feasibility of patients with end-stage organ failure completing the ICECAP-SCM

BACKGROUND

The ICECAP-Supportive Care Measure (SCM) is a self-complete measure developed to inform economic decision making at the end-of-life. Previous research has demonstrated its feasibility in hospice and nursing home settings. This is the first study of its use with patients on the organ failure trajectory.

AIM

To determine the feasibility of using the ICECAP-SCM with patients experiencing end-stage organ failure in a hospital setting.

DESIGN

Participants were asked to 'think aloud' when completing the ICECAP-SCM, ICECAP-A and EQ-5D-5L measures. The interviews were transcribed verbatim and examined for errors in comprehension, retrieval, judgement, and response by five raters. Qualitative data were collected to explore reasons for errors in completing the measures and participants' views about the measures.

SETTING/PARTICIPANTS

Sixty patients (with end-stage renal failure n = 18; end-stage heart failure n = 21; end-stage chronic obstructive pulmonary disease n = 21) participated. Senior clinicians applied prognostic criteria to determine eligibility.

RESULTS

Participants reported that the measures were acceptable, clear, and easy to complete. Error rates in completing the measures were low (ICECAP-A = 3%,and ICECAP-SCM = 5.7% and EQ-5D-5L = 6.3%). There was some variation in responses between patients with different end-stage conditions, particularly those with symptom fluctuation. Some patients had not considered their end-of-life (i.e. advance care planning) and reported finding questions about this difficult to answer.

CONCLUSION

It is feasible to use the ICECAP-SCM with patients with end-stage organ failure receiving care in hospital settings. This study provides evidence for researchers and policy makers involved in measuring end-of-life care globally. The ICECAP-SCM can be recommended for research with patients in end-stage organ failure to appropriately capture the broader benefits of end-of-life care.

Palliative care symptoms, concerns and well-being of older people with frailty and complex care needs upon hospital discharge: a cross-sectional study

Background

Little is known about the nature and intensity of palliative care needs of hospitalised older people. We aimed to describe the palliative care symptoms, concerns, and well-being of older people with frailty and complex care needs upon discharge from hospital to home, and to examine the relationship between palliative care symptoms and concerns, and well-being.

Methods

Cross-sectional study using baseline survey data of a pilot randomised controlled trial. Hospital staff identified patients (≥ 70 years) about to be discharged home, with a clinical frailty score of 5 to 7 and complex needs based on physician-assessment. Patients completed structured interviews, using the Integrated Palliative Care Outcome Scale (IPOS), ICEpop CAPability measure for supportive care (ICECAP-SCM) and IPOS Views on Care quality of life item. We calculated descriptive statistics.

Results

We assessed 37 older people with complex needs (49% women, mean age 84, standard deviation 6.1). Symptoms rated as causing severe problems were weakness (46%) and poor mobility (40%); 75% reported that their family felt anxious at least occasionally. Of the 17 IPOS items, 41% of patients rated five or more symptoms as causing severe problems, while 14% reported that they were not severely affected by any symptom. 87% expressed feeling supported. There was a negative correlation between symptoms (IPOS) and well-being (ICECAP); r = -0.41.

Conclusion

We identified a large variety of symptoms experienced by older people identified as having frailty and complex needs upon hospital discharge. Many were severely affected by multiple needs. This population should be considered for palliative care follow-up at home.

An analysis of the construct validity and responsiveness of the ICECAP-SCM capability wellbeing measure in a palliative care hospice setting

BACKGROUND

For outcome measures to be useful in health and care decision-making, they need to have certain psychometric properties. The ICECAP-Supportive Care Measure (ICECAP-SCM), a seven attribute measure (1. Choice, 2. Love and affection, 3. Physical suffering, 4. Emotional suffering, 5. Dignity, 6. Being supported, 7. Preparation) developed for use in economic evaluation of end-of-life interventions, has face validity and is feasible to use. This study aimed to assess the construct validity and responsiveness of the ICECAP-SCM in hospice inpatient and outpatient settings.

METHODS

A secondary analysis of data collated from two studies, one focusing on palliative care day services and the other on constipation management, undertaken in the same national hospice organisation across three UK hospices, was conducted. Other quality of life and wellbeing outcome measures used were the EQ-5D-5L, McGill Quality of Life Questionnaire - Expanded (MQOL-E), Patient Health Questionnaire-2 (PHQ-2) and Palliative Outcomes Scale Symptom list (POS-S). The construct validity of the ICECAP-SCM was assessed, following hypotheses generation, by calculating correlations between: (i) its domains and the domains of other outcome measures, (ii) its summary score and the other measures' domains, (iii) its summary score and the summary scores of the other measures. The responsiveness of the ICECAP-SCM was assessed using anchor-based methods to understand change over time. Statistical analysis consisted of Spearman and Pearson correlations for construct validity and paired t-tests for the responsiveness analysis.

RESULTS

Sixty-eight participants were included in the baseline analysis. Five strong correlations were found with ICECAP-SCM attributes and items on the other measures: four with the Emotional suffering attribute (Anxiety/depression on EQ-5D-5L, Psychological and Burden on MQOL-E and Feeling down, depressed or hopeless on PHQ-2), and one with Physical suffering (Weakness or lack of energy on POS-S). ICECAP-SCM attributes and scores were most strongly associated with the MQOL-E measure (0.73 correlation coefficient between summary scores). The responsiveness analysis (n = 36) showed the ICECAP-SCM score was responsive to change when anchored to changes on the MQOL-E over time (p < 0.05).

CONCLUSIONS

This study provides initial evidence of construct validity and responsiveness of the ICECAP-SCM in hospice settings and suggests its potential for use in end-of-life care research.

An Economic Evaluation Supported by Qualitative Data About the Patient Concerns Inventory (PCI) versus Standard Treatment Pathway in the Management of Patients with Head and Neck Cancer

BACKGROUND

The head and neck cancer (HNC) Patient Concerns Inventory (PCI) is a condition-specific prompt list that allows patients to raise concerns to cancer consultants that otherwise might be overlooked.

OBJECTIVE

This is the first economic evaluation of the PCI in patients with HNC investigating the costs and effects to the health service of not prioritising certain treatment pathways in addition to the primary cancer pathway. Additional costs can be accrued due to delayed referral to other appropriate services, e.g. hospital dentist. Economic evidence could influence future policy direction in this area globally.

METHODS

Alongside a 3-year clustered randomised controlled trial, an economic evaluation was undertaken with Client Service Receipt Inventory data collected at three different time points (baseline and 6 and 12 months post-baseline). Patients were identified by a multidisciplinary team at the trial clinics. This economic analysis compared the PCI intervention versus the non-PCI treatment pathway. A deterministic and probabilistic sensitivity analysis was conducted to investigate the cost per quality-adjusted life-year (QALY) gain of the PCI versus non-PCI intervention treatment pathways. Qualitative data were also collected from seven consultants to triangulate findings from the economic evaluation.

RESULTS

The analysis used data from 191 patients (66% of the full trial sample). The PCI inventory was low cost, at just over £13 per participant. The PCI intervention was cost effective and also cost saving, with an incremental cost difference of £295.91 over the 12-month follow-up period. The QALY values were higher in the PCI intervention strategy, with a value of 0.79, whereas the non-PCI group had a value of 0.76, thus the PCI intervention was dominant. The sensitivity analysis showed that, at a willingness-to-pay threshold of £20,000 per QALY gained, the probability of being cost effective was 0.85 (95% confidence interval [CI] 0.80-0.83). Qualitative results showed that consultants using the PCI reported an enhanced awareness of patients' overall post-treatment needs.

DISCUSSION

The PCI provided an effective means to conduct clinical consultations by avoiding unnecessary healthcare costs and focussing on aspects of care most important to patients. The cost per QALY gain was within the National Institute for Health and Care Excellence guideline threshold. The economic evaluation showed that the PCI intervention strategy was dominant and therefore cost saving to the national health service (NHS) and was more effective in terms of treatment.

CONCLUSION

The PCI appears to be a low-cost intervention that generates a cost-effective benefit to patients from a NHS perspective if rolled out as part of routine care. Qualitative evidence has shown that the use of the PCI is supported by consultants in routine practice.

Qualitative Review on Domains of Quality of Life Important for Patients, Social Care Users, and Informal Carers to Inform the Development of the EQ-HWB

OBJECTIVES

To identify the themes to inform the content of a new generic measure, the EQ-HWB (EQ Health and Wellbeing), that can be used in economic evaluation across health, social care, and public health, based on the views of users and beneficiaries of these services including informal carers.

METHODS

A qualitative review was undertaken. Systematic and citation searches were undertaken focusing on qualitative evidence of the impact on quality of life from reviews for selected health conditions, informal carers, social care users, and primary qualitative work used in the development of selected measures. A subset of studies was included in the review. Framework analysis and synthesis were undertaken based on a conceptual model.

RESULTS

A total of 42 reviews and 24 primary studies were selected for inclusion in the review. Extraction and synthesis resulted in 7 high-level themes (with subthemes): (1) feelings and emotions (sadness, anxiety, hope, frustration, safety, guilt/shame); (2) cognition (concentration, memory, confusion, thinking clearly); (3) self-identity (dignity/respect, self-esteem); (4) "coping, autonomy, and control" relationships; (5) social connections (loneliness, social engagement, stigma, support, friendship, belonging, burden); (6) physical sensations (pain, discomfort, sleep, fatigue); and (7) activity (self-care, meaningful activities, mobility, communication, hearing, vision). Apart from physical sensations, most of the other themes and subthemes were relevant across both health and social care, including for informal carers.

CONCLUSIONS

The findings from this broad review identified themes that go beyond health and that are relevant to patients, informal carers, and social care users. The themes and subthemes informed the domains for the EQ-HWB.

The Children and Young People Quality of Life Study: A protocol for the qualitative development of attributes for capability wellbeing measures for use in health economic evaluation with children and young people

Background: Health services face difficult choices regarding how to allocate scarce health and social care resources. Economic evaluation can aid this process of decision making by allowing competing healthcare interventions or services to be compared in terms of their costs and consequences. However, existing use of economic evaluation of health services largely focuses on comparing interventions in terms of their impact on health only, missing factors potentially important to broader wellbeing. The capability approach measures outcomes in terms of what people are able to do and be. It provides an alternative evaluative space for economic evaluation, which may be especially beneficial for populations such as children and young people, for whom health might not be the only outcome of importance to their wellbeing. Study aims: This study aims to develop conceptual attributes and descriptive systems for capability wellbeing measures for children and young people to be used in economic evaluation, using qualitative methods with children and young people directly and their parents/guardians. Methods: Qualitative interviews will be used with children and young people and parents/guardians to develop the conceptual attributes (items) and wording for the capability wellbeing measures. Recruitment will be undertaken through organisations such as schools and charities and online using Facebook. Interviews will be face-to-face or online and will focus on identifying factors important to children and young people’s wellbeing to create an initial draft of the capability wellbeing measures. Subsequent interviews will focus on refining the wording used in the measures. Interviews will be analysed using methods of constant comparison, to explore similarities and differences in what participants considered important to children and young people’s wellbeing and to develop appropriate wording for the measures based on participant responses. Ethics: The study received approval from the University of Bristol Faculty of Health Sciences Research Ethics Committee (reference 77121).

Measuring What Matters-A Holistic Approach to Measuring Well-Being in Endometriosis

Endometriosis is a common condition which affects women in a number of ways and impairs their ability to live a full and meaningful life. Evaluative research has traditionally taken its cue from a medical approach which has forced women to choose one area of functioning as their primary concern, and tended to use a narrow definition of treatment success which ignores general well-being. While recent trials have included quality of life (QOL) measures as outcomes, these have not been able to capture the totality of the impact of the disease and its treatment on a woman's capability to do what she might want to do and be who she might want to be. A capability approach might overcome this barrier, but the available tools will need to be refined and validated in women with endometriosis before this can be integrated within everyday clinical and research practice.

Conceptualising 'Benefits Beyond Health' in the Context of the Quality-Adjusted Life-Year: A Critical Interpretive Synthesis

There is growing interest in extending the evaluative space of the quality-adjusted life-year framework beyond health. Using a critical interpretive synthesis approach, the objective was to review peer-reviewed literature that has discussed non-health outcomes within the context of quality-adjusted life-years and synthesise information into a thematic framework. Papers were identified through searches conducted in Web of Science, using forward citation searching. A critical interpretive synthesis allows for the development of interpretations (synthetic constructs) that go beyond those offered in the original sources. The final output of a critical interpretive synthesis is the synthesising argument, which integrates evidence from across studies into a coherent thematic framework. A concept map was developed to show the relationships between different types of non-health benefits. The critical interpretive synthesis was based on 99 papers. The thematic framework was constructed around four themes: (1) benefits affecting well-being (subjective well-being, psychological well-being, capability and empowerment); (2) benefits derived from the process of healthcare delivery; (3) benefits beyond the recipient of care (spillover effects, externalities, option value and distributional benefits); and (4) benefits beyond the healthcare sector. There is a wealth of research concerning non-health benefits and the evaluative space of the quality-adjusted life-year. Further dialogue and debate are necessary to address conceptual and normative challenges, to explore the societal willingness to sacrifice health for benefits beyond health and to consider the equity implications of different courses of action.

Challenges in developing capability measures for children and young people for use in the economic evaluation of health and care interventions

Methods for measuring outcomes suitable for economic evaluations of health and care interventions have primarily focused on adults. The validity of such methods for children and young people is questionable in areas including the outcome domains measured and how they are measured and valued, with most existing measures narrowly focusing on health. Novel methods for assessing benefits beyond health by focusing on a person's capability have also concentrated on adults to date. This paper aims to set out the rationale for capability measures in children and young people. It argues for the need to expand the evaluative space beyond health functioning towards broader capabilities, with children and young people playing an integral role in capability measure development. Drawing from existing literature, specific challenges related to the identification, measurement, and valuation of capabilities in children and young people are also discussed. Finally, the practical implications for conducting economic evaluation when measuring and valuing capabilities at different stages across the life-course are illustrated. We develop an alternative framework based on conceiving capabilities as evolving across the life-course. This framework may also be helpful in thinking about how to model health outcomes across the life-course.

"It is not a scientific number it is just a feeling": Populating a multi-dimensional end-of-life decision framework using deliberative methods

The capability approach is potentially valuable for economic evaluation at the end of life because of its conceptualization of wellbeing as freedom and the potential for capturing outcomes for those at end of life and those close to persons at the end of life. For decision making, however, this information needs to be integrated into current evaluation paradigms. This research explored weights for an integrated economic evaluation framework using a deliberative approach. Twelve focus groups were held (38 members of the public, 29 "policy makers," seven hospice volunteers); budget pie tasks were completed to generate weights. Constant comparison was used to analyze qualitative data, exploring principles behind individuals' weightings. Average weights elicited from members of the general population and policy makers for the importance that should be given to close persons (vs. patients) were very similar, at around 30%. A "sliding scale" of weights between health gain and the capability for a good death resulted from the policy maker and volunteer groups, with increasing weight given to the capability for a good death as the trajectory got closer to death. These weights can be used in developing a more comprehensive framework for economic evaluation at end of life.

Palliative care in day-hospital for advanced cancer patients: a study protocol for a multicentre randomized controlled trial

Background

Team-based and timely integrated palliative care is a gold standard of care in oncology, but issues concerning its optimal organization remain. Palliative Care in Day-Hospital (PCDH) could be one of the most efficient service model of palliative care to deliver interdisciplinary and multidimensional care addressing the complex supportive care needs of patients with advanced cancer. We hypothesize that, compared to conventional outpatient palliative care, PCDH allows the clinical benefits of palliative care to be enhanced.

Methods/design

This study is a multicentre parallel group trial with stratified randomization. Patient management in PCDH will be compared to conventional outpatient palliative care. The inclusion criteria are advanced cancer patients referred to a palliative care team with an estimated life expectancy of more than 2 months and less than 1 year. The primary endpoint is health-related quality of life with deterioration-free survival based on the EORTC QLQ-C30 questionnaire. The secondary objectives are the following: increase in patient satisfaction with care using the EORTC PATSAT-C33 and OUT-PATSAT7 questionnaires, better understanding of the prognosis using the PTPQ questionnaire and advance care planning; decrease in the need for supportive care among relatives using the SCNS-P&C-F questionnaire, and reduction in end-of-life care aggressiveness. Patients will complete one to five questionnaires on a tablet before each monthly visit over 6 months and will be followed for 1 year. A qualitative study will take place, aiming to understand the specificity of palliative care management in PCDH. Cost-effectiveness, cost-utility and, an additional economic evaluation based on capability approach will be conducted from a societal point of view.

Discussion

The first strength of this study is that it combines the main relevant outcomes assessing integrated palliative care; patient quality of life and satisfaction; discussion of the prognosis and advance care planning, family well-being and end-of-life care aggressiveness. The second strength of the study is that it is a mixed-method study associating a qualitative analysis of the specificity of PCDH organization, with a medical-economic study to analyse the cost of care.

German tariffs for the ICECAP-Supportive Care Measure (ICECAP-SCM) for use in economic evaluations at the end of life

OBJECTIVES

Economic evaluations often use preference-based value sets (tariffs) for health-related quality of life to quantify health effects. For wellbeing at the end of life, issues beyond health-related quality of life may be important. Therefore, the ICECAP Supportive Care Measure (ICECAP-SCM), based on the capability approach, was developed. A validated German ICECAP-SCM version was published recently. However, tariffs for the German ICECAP-SCM are not available. Therefore, the aim was to determine tariffs for the ICECAP-SCM based on preferences of the German general population.

METHODS

An online sample of 2996 participants completed a best-worst scaling (BWS) and a discrete choice experiment (DCE). BWSs required participants to choose the best and worst statement within the same capability state, whereas DCEs required participants to trade-off between two capability states. First, BWS and DCE data were analyzed separately. Subsequently, combined data were analyzed using scale-adjusted conditional logit latent class models. Models were selected based on the stability of solutions and the Bayesian information criterion.

RESULTS

The two latent class model was identified to be optimal for the BWS, DCE, and combined data, and was used to derive tariffs for the ICECAP-SCM capability states. BWS data captured differences in ICECAP-SCM scale levels, whereas DCE data additionally explained interactions between the seven ICECAP-SCM attributes.

DISCUSSION

The German ICECAP-SCM tariffs can be used in addition to health-related quality of life to quantify effectiveness in economic evaluations. The tariffs based on BWS data were similar for Germany and the UK, whereas the tariffs based on combined data varied. We would recommend to use tariffs based on combined data in German evaluations. However, only results on BWS data are comparable between Germany and the UK, so that tariffs based on BWS data should be used when comparing results between Germany and the UK.

Self- and proxy-rating of the ICECAP-O for people with dementia: A cross-sectional linguistic validation study in Germany and Portugal

BACKGROUND

The capability concept became a recognized approach to the measurement of quality of life. The ICECAP-O for older people aims to measure capabilities and has recently been used in people with dementia (self-rating) and informal carers (substituted judgement). However, linguistic validation studies have so far been lacking.

METHODS

A cross-sectional cognitive interview study with 15 people with dementia (PwD) and 23 informal carers (ICs) was conducted in Germany and Portugal. Respondents were asked to reveal their understanding of the ICECAP-O and the capability approach as well as the response process. A summarising content analysis was performed.

RESULTS

Despite the small sample, our linguistic validation of the German and Portuguese translations detected considerable difficulties or deviations in item comprehension when compared with the intended meaning. In some cases, the item interpretations did not reflect the entire scope of the associated capability dimension, though they were basically correct. Moreover, participants were not able to differentiate some items appropriately from one another, and some misinterpretations occurred. ICs relied mainly on observable behaviour, emotions, or verbal expressions of the PwD. Therefore, ICs found items that ask about the achievement of individual expectations or thoughts about the future difficult to assess. Only very few PwD clearly indicated that they understood the capability approach. ICs in Germany had more difficulties in understanding the capability concept than in ICs Portugal.

DISCUSSION

This linguistic validation study in Germany and Portugal indicates a need for some rephrasing and refinements of the ICECAP-O translated items in both countries to fully encompass some dimensions and avoid misinterpretations. Further studies with larger samples are necessary. Based on our findings, the current German version for ICs' substituted judgement cannot be recommended for this kind of respondents without further advancements.

Measuring capabilities in health and physical activity promotion: a systematic review

BACKGROUND

The capability approach by Amartya Sen and Martha Nussbaum has gained increasing attention in the field of public health. As it combines individual, social and structural factors and shifts the focus of attention from the actual behavior towards available options for health behaviors that people can actually choose from, it may help advance our understanding of complex health issues.

OBJECTIVES

The aim of this article is to identify and describe tools available to measure capabilities within the context of health, with a specific focus on capabilities for health-enhancing physical activity.

METHOD

We conducted a systematic literature review using 11 databases covering scientific journal articles published in English or German between the years 2000 and 2020 with a focus on capabilities for health or physical activity.

RESULTS

We found a total of 51 articles meeting our inclusion criteria. Four articles measured capabilities using qualitative methods, one combined qualitative and quantitative methods, while the rest used quantitative methods. We identified a total 11 different capability questionnaires, all showing moderate to good validity/reliability. Only one questionnaire and one interview-based tool specifically dealt with capabilities for health enhancing physical activity.

CONCLUSION

Although we were able to identify measurement tools for capabilities in health, this review has shown that there is no generic tool available for the measurement across all population- and age-groups, and tools focusing on physical activity are scarce. However, our results can be used as guide for future projects that aim at measuring capabilities.

Valuing end-of-life care: translation and content validation of the ICECAP-SCM measure

Background

The evaluation of care strategies at the end of life is particularly important due to the globally increasing proportion of very old people in need of care. The ICECAP-Supportive Care Measure is a self-complete questionnaire developed in the UK to evaluate palliative and supportive care by measuring patient’s wellbeing in terms of ‘capability’. It is a new measure with high potential for broad and international use. The aims of this study were the translation of the ICECAP-Supportive Care Measure from English into German and the content validation of this version.

Methods

A multi-step and team-based translation process based on the TRAPD model was performed. An expert survey was carried out to assess content validity. The expert panel (n = 20) consisted of four expert groups: representative seniors aged 65+, patients aged 65+ living in residential care, patients aged 65+ receiving end-of-life care, and professionals in end-of-life care.

Results

The German version of the ICECAP-Supportive Care Measure showed an excellent content validity on both item- and scale-level. In addition, a high agreement regarding the length of the single items and the total length of the questionnaire as well as the number of answer categories was reached.

Conclusions

The German ICECAP-SCM is a valid tool to assess the quality of life at the end of life that is suitable for use in different settings. The questionnaire may be utilized in multinational clinical and economic evaluations of end-of-life care.

Measuring capability wellbeing in adults at different stages of life for use in economic evaluation of health and care interventions: a qualitative investigation in people requiring kidney care

PURPOSE

Capability wellbeing measures, such as the ICECAP measures, have been proposed for use in economic evaluations to capture broader outcomes of health and care interventions. The ICECAP measures have been developed to reflect capabilities at different stages of life. Some patient groups include patients of different ages and at different stages of life, so it is not always apparent which ICECAP measure is most relevant. This study explores the impact of age and life stage on completion, where both ICECAP-A and ICECAP-O were completed by the same patient.

METHODS

A think-aloud study, and an associated semi-structured interview were conducted with people receiving kidney care as a renal outpatient, kidney transplant outpatient, or through receiving facility-based haemodialysis. Qualitative analysis focused on (1) differences in responses across measures by individuals, where attributes had conceptual overlap, (2) key factors in self-reported capability levels, and (3) measure preference.

RESULTS

Thirty participants were included in the study, with a mix of older and younger adults. Attributes with similar wording across measures produced similar responses compared to attributes where wording differed. Age and health were key factors for self-reported capability levels. ICECAP-A was slightly preferred overall, including by older adults.

CONCLUSION

This study suggests use of ICECAP-A in patients with certain chronic health conditions that include a mix of adults across the life course. This study highlights the importance of considering the stage of life when using capability measures and in economic evaluations of health and care interventions more generally.

Selection and validation of a classification system for a child-centred preference-based measure of oral health-related quality of life specific to dental caries

Background

Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) is a child-centred caries-specific quality of life measure. This study aimed to select, and validate with children, a classification system for a paediatric condition-specific preference-based measure, based on CARIES-QC.

Methods

First, a provisional classification system for a preference-based measure based on CARIES-QC was identified using Rasch analysis, psychometric testing, involvement of children and parents, and the developer of CARIES-QC. Second, qualitative, semi-structured ‘think aloud’ validation interviews were undertaken with a purposive sample of children with dental caries. The interviewer aimed to identify whether items were considered important and easily understood, whether any were overlapping and if any excluded items should be reintroduced. Interview recordings were transcribed verbatim and thematic analysis conducted.

Results

Rasch analysis identified poor item spread for the items ‘cross’ and ‘school’. Items relating to eating were correlated and the better performing items were considered for selection. Children expressed some confusion regarding the items ‘school’ and ‘food stuck’. Parent representatives thought that impacts surrounding toothbrushing (‘brushing’) were encompassed by the item ‘hurt’. Five items were selected from CARIES-QC for inclusion in the provisional classification system; ‘hurt’, ‘annoy’, ‘carefully’, ‘kept awake’ and ‘cried’. Validation interviews were conducted with 20 children aged 5–16 years old. Participants thought the questionnaire was straightforward and covered a range of impacts. Children thought an item about certain foods being ‘hard to eat’ was more relevant than one about having to eat more carefully because of their teeth and so the ‘carefully’ item was replaced with ‘hard to eat’.

Conclusion

Following child-centred modification, the preliminary five-item classification system is considered valid and suitable for use in a valuation survey. The innovative child-centred methods used to both identify and validate the classification system can be applied in the development of other preference-based measures.

Psychometric Properties of the EQ-5D for the Assessment of Health-Related Quality of Life in the Population of Middle-Old and Oldest-Old Persons: Study Protocol for a Systematic Review

Introduction: Health care interventions for middle-old and oldest-old individuals (75 years or older) are often economically evaluated using the EuroQol questionnaire (EQ-5D) to measure health-related quality of life. However, the psychometric performance of the EQ-5D in this population has been questioned, as it probably does not adequately capture relevant aspects of quality of life in the older population. Because the results of economic evaluations using the EQ-5D often guide decision-makers, it is important to know whether the EQ-5D has satisfactory psychometric properties in the middle-old and oldest-old population. Therefore, studies assessing the psychometric properties of the EQ-5D in this population should be synthesized by a systematic review. Methods and Analysis: A systematic review of studies providing empirical evidence of reliability, validity, and/or responsiveness of the EQ-5D in a sample with a mean age ≥75 years will be conducted. The databases PubMed, Web of Science, and EconLit will be searched. In addition, reference lists of included studies will be hand-searched. Two independent reviewers will select studies and assess their risk of bias with the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) Risk of Bias checklist. Relevant data will be extracted by one reviewer and cross-checked by a second reviewer. Potential disagreements in any phase will be resolved through discussion with a third person. The guidelines for systematic reviews of measurement properties proposed by the COSMIN group, including criteria of good measurement properties, will guide the synthesis and interpretation of the results. Discussion: The review's results could facilitate the making of recommendations for the use of the EQ-5D in a population of middle-old and oldest-old people and thereby being of interest for decision-makers or for researchers designing new intervention studies for older people. Heterogeneity of individual studies regarding the population under study could limit the possibility of making a synthesized statement on the appropriateness of the EQ-5D for the middle-old to oldest-old population.

Empirical Validity of a Generic, Preference-Based Capability Wellbeing Instrument (ICECAP-A) in the Context of Spinal Cord Injury

BACKGROUND

Assessing the validity of generic instruments across different clinical contexts is an important area of methodological research in economic evaluation and outcomes measurement.

OBJECTIVE

Our objective was to examine the empirical validity of a generic, preference-based capability wellbeing instrument (ICECAP-A) in the context of spinal cord injury.

METHODS

This study consisted of a secondary analysis of data collected using an online cross-sectional survey. The survey included questions regarding demographics, injury classifications and characteristics, secondary health conditions, quality of life and wellbeing, and functioning in activities of daily living. Analysis comprised the descriptive assessment of Spearman's rank correlations between item-/dimension-level data for the ICECAP-A and four preference-based health-related quality of life (HRQoL) instruments, and discriminant and convergent validity approaches to examine 21 evidence-informed or theoretically derived constructs. Constructs were defined using participant and injury characteristics and responses to a range of health, wellbeing and functioning outcomes.

RESULTS

Three hundred sixty-four individuals completed the survey. Mean index score for the ICECAP-A was 0.761; 12 (3%) individuals reported full capability (upper anchor; score = 1), and there were no reports of zero capabilities (lower anchor; score = 0). The strongest correlations were dominated by items and dimensions on the comparator (HRQoL) instruments that are non-health aspects of quality of life, such as happiness and control over one's life (including self-care). Of 21 hypothesised constructs, 19 were confirmed in statistical tests, the exceptions being the exploratory hypotheses regarding education and age at injury.

CONCLUSION

The ICECAP-A is an empirically valid outcome measure for assessing capability wellbeing in people with spinal cord injury living in a community setting. The extent to which the ICECAP-A provides complementary information to preference-based HRQoL instruments is dependent on the comparator.

Decreased costs and retained QoL due to the 'PACE Steps to Success' intervention in LTCFs: cost-effectiveness analysis of a randomized controlled trial

BACKGROUND

The number of residents in long-term care facilities (LTCFs) in need of palliative care is growing in the Western world. Therefore, it is foreseen that significantly higher percentages of budgets will be spent on palliative care. However, cost-effectiveness analyses of palliative care interventions in these settings are lacking. Therefore, the objective of this paper was to assess the cost-effectiveness of the 'PACE Steps to Success' intervention. PACE (Palliative Care for Older People) is a 1-year palliative care programme aiming at integrating general palliative care into day-to-day routines in LTCFs, throughout seven EU countries.

METHODS

A cluster RCT was conducted. LTCFs were randomly assigned to intervention or usual care. LTCFs reported deaths of residents, about whom questionnaires were filled in retrospectively about resource use and quality of the last month of life. A health care perspective was adopted. Direct medical costs, QALYs based on the EQ-5D-5L and costs per quality increase measured with the QOD-LTC were outcome measures.

RESULTS

Although outcomes on the EQ-5D-5L remained the same, a significant increase on the QOD-LTC (3.19 points, p value 0.00) and significant cost-savings were achieved in the intervention group (€983.28, p value 0.020). The cost reduction mainly resulted from decreased hospitalization-related costs (€919.51, p value 0.018).

CONCLUSIONS

Costs decreased and QoL was retained due to the PACE Steps to Success intervention. Significant cost savings and improvement in quality of end of life (care) as measured with the QOD-LTC were achieved. A clinically relevant difference of almost 3 nights shorter hospitalizations in favour of the intervention group was found. This indicates that timely palliative care in the LTCF setting can prevent lengthy hospitalizations while retaining QoL. In line with earlier findings, we conclude that integrating general palliative care into daily routine in LTCFs can be cost-effective.

Exploring the costs, consequences and efficiency of three types of palliative care day services in the UK: a pragmatic before-and-after descriptive cohort study

Background

Palliative Care Day Services (PCDS) offer supportive care to people with advanced, progressive illness who may be approaching the end of life. Despite the growth of PCDS in recent years, evidence of their costs and effects is scarce. It is important to establish the value of such services so that health and care decision-makers can make evidence-based resource allocation decisions. This study examines and estimates the costs and effects of PCDS with different service configurations in three centres across the UK in England, Scotland and Northern Ireland.

Methods

People who had been referred to PCDS were recruited between June 2017 and September 2018. A pragmatic before-and-after descriptive cohort study design analysed data on costs and outcomes. Data on costs were collected on health and care use in the 4 weeks preceding PCDS attendance using adapted versions of the Client Service Receipt Inventory (CSRI). Outcomes, cost per attendee/day and volunteer contribution to PCDS were also estimated. Outcomes included quality of life (MQOL-E), health status (EQ-5D-5L) and capability wellbeing (ICECAP-SCM).

Results

Thirty-eight attendees were recruited and provided data at baseline and 4 weeks (centre 1: n = 8; centre 2: n = 8, centre 3: n = 22). The cost per attendee/day ranged from £121–£190 (excluding volunteer contribution) to £172–£264 (including volunteer contribution) across the three sites. Volunteering constituted between 28 and 38% of the total cost of PCDS provision. There was no significant mean change at 4 week follow-up from baseline for health and care costs (centre 1: £570, centre 2: -£1127, centre 3: £65), or outcomes: MQOL-E (centre 1: − 0.48, centre 2: 0.01, centre 3: 0.24); EQ-5D-5L (centre 1: 0.05, centre 2: 0.03, centre 3: − 0.03) and ICECAP-SCM (centre 1:0.00, centre 2: − 0.01, centre 3: 0.03). Centre costs variation is almost double per attendee when attendance rates are held constant in scenario analysis.

Conclusions

This study highlights the contribution made by volunteers to PCDS provision. There is insufficient evidence on whether outcomes improved, or costs were reduced, in the three different service configurations for PCDS. We suggest how future research may overcome some of the challenges we encountered, to better address questions of cost-effectiveness in PCDS.

Understanding the Outcomes of Supplementary Support Services in Palliative Care for Older People. A Scoping Review and Mapping Exercise

CONTEXT

Supplementary support services in palliative care for older people are increasingly common, but with neither recommended tools to measure outcomes nor reviews synthesizing anticipated outcomes. Common clinically focused tools may be less appropriate.

OBJECTIVES

To identify stakeholder perceptions of key outcomes from supplementary palliative care support services, then map these onto outcome measurement tools to assess relevance and item redundancy.

METHODS

A scoping review using the design by Arksey and O'Malley. EMBASE, CINAHL, MEDLINE, and PSYCHinfo searched using terms relating to palliative care, qualitative research, and supplementary support interventions. Articles were imported into Endnote™, and Covidence™ was used by two reviewers to assess against inclusion criteria. Included articles were imported into NVivo™ and thematically coded to identify key concepts underpinning outcomes. Each item within contender outcome measurement tools was assessed against each concept.

RESULTS

Sixty included articles focused on advance care planning, guided conversations, and volunteer befriending services. Four concepts were identified: enriching relationships; greater autonomy and perceived control; knowing more; and improved mental health. Mapping concepts to contender tool items revealed issues of relevance and redundancy. Some tools had no redundant items but mapped only to two of four outcome themes; others mapped to all concepts, but with many redundant questions. Tools such as ICECAP-Supportive Care Measure and McGill Quality of Life had high relevance and low redundancy.

CONCLUSION

Pertinent outcome concepts for these services and population are not well represented in commonly used outcome measurement tools, and this may have implications in appropriately measuring outcomes. This review and mapping method may have utility in fields where selecting appropriate outcome tools can be challenging.

Proxy responses to ICECAP-A: Exploring variation across multiple proxy assessments of capability well-being for the same individuals

Background

The ICECAP capability measures are increasingly being used to capture the impact of health and social care interventions on well-being. In cases where the recipient of an intervention is highly vulnerable, proxy completion may be necessary. This study adds to the limited existing evidence on proxy completion of ICECAP-A specifically and adopts the novel approach of investigating multiple proxy responses for the same four (hypothetical) individuals.

Methods

62 members of the public who were participating in a series of one day deliberative workshops on public health and social care completed ICECAP-A on behalf of four hypothetical individuals, described in vignettes. Quantitative analysis explored the range of proxy responses for each of the four hypothetical individuals, and any possible correlation between participants’ own characteristics and their proxy responses. Participants discussed their proxy responses after completing the task; this discussion was audio recorded and analysed using Framework Analysis.

Results

Wide variation in ICECAP-A scores was observed across proxy respondents for each hypothetical individual. Participants’ demographic characteristics and own well-being do not appear to have systematically influenced proxy responses. Qualitative analysis suggests two principal approaches (or perspectives) were adopted by participants: Empathetic (adopting the perspective of the ‘subject’) and factual (a factual assessment of the subject’s well-being). Participants also drew on their own experiences to varying degrees. There were differing interpretations of the Independence attribute on ICECAP-A and some evidence that participants’ ideas of what constituted achievement were context (including life-stage and condition/health) specific.

Conclusions

The factual versus empathetic approaches identified from qualitative analysis in this study match to the concept of a proxy-proxy versus proxy-patient perspective, previously outlined in the literature. Researchers should consider specifying which perspective proxy raters should adopt. Findings also suggest proxy responses can be influenced by external points of reference and interpretation of measure attributes.

Capability instruments in economic evaluations of health-related interventions: a comparative review of the literature

PURPOSE

Given increasing interest in using the capability approach for health economic evaluations and a growing literature, this paper aims to synthesise current information about the characteristics of capability instruments and their application in health economic evaluations.

METHODS

A systematic literature review was conducted to assess studies that contained information on the development, psychometric properties and valuation of capability instruments, or their application in economic evaluations.

RESULTS

The review identified 98 studies and 14 instruments for inclusion. There is some evidence on the psychometric properties of most instruments. Most papers found moderate-to-high correlation between health and capability measures, ranging between 0.41 and 0.64. ASCOT, ICECAP-A, -O and -SCM instruments have published valuation sets, most frequently developed using best-worst scaling. Thirteen instruments were originally developed in English and one in Portuguese; however, some translations to other languages are available. Ten economic evaluations using capability instruments were identified. The presentation of results show a lack of consensus regarding the most appropriate way to use capability instruments in economic evaluations with discussion about capability-adjusted life years (CALYs), years of capability equivalence and the trade-off between maximisation of capability versus sufficient capability.

CONCLUSION

There has been increasing interest in applying the capability-based approach in health economic evaluations, but methodological and conceptual issues remain. There is still a need for direct comparison of the different capability instruments and for clear guidance on when and how they should be used in economic evaluations.

A group intervention to improve quality of life for people with advanced dementia living in care homes: the Namaste feasibility cluster RCT

BACKGROUND

People with advanced dementia who live and die in nursing homes experience variable quality of life, care and dying. There is a need to identify appropriate, cost-effective interventions that facilitate high-quality end-of-life care provision.

OBJECTIVES

To establish the feasibility and acceptability to staff and family of conducting a cluster randomised controlled trial of the Namaste Care intervention for people with advanced dementia in nursing homes.

DESIGN

The study had three phases: (1) realist review and (2) intervention refinement to inform the design of (3) a feasibility cluster randomised controlled trial with a process evaluation and economic analysis. Clusters (nursing homes) were randomised in a 3 : 1 ratio to intervention or control (usual care). The nature of the intervention meant that blinding was not possible.

SETTING

Nursing homes in England providing care for people with dementia.

PARTICIPANTS

Residents with advanced dementia (assessed as having a Functional Assessment Staging Test score of 6 or 7), their informal carers and nursing home staff.

INTERVENTION

Namaste Care is a complex group intervention that provides structured personalised care in a dedicated space, focusing on enhancements to the physical environment, comfort management and sensory engagement.

MAIN OUTCOME MEASURES

The two contender primary outcome measures were Comfort Assessment in Dying - End of Life Care in Dementia for quality of dying (dementia) and Quality of Life in Late Stage Dementia for quality of life. The secondary outcomes were as follows: person with dementia, sleep/activity (actigraphy), neuropsychiatric symptoms, agitation and pain; informal carers, satisfaction with care at the end of life; staff members, person-centred care assessment, satisfaction with care at the end of life and readiness for change; and other data - health economic outcomes, medication/service use and intervention activity.

RESULTS

Phase 1 (realist review; 86 papers) identified that a key intervention component was the activities enabling the development of moments of connection. In phase 2, refinement of the intervention enabled the production of a user-friendly 16-page A4 booklet. In phase 3, eight nursing homes were recruited. Two homes withdrew before the intervention commenced; four intervention and two control homes completed the study. Residents with advanced dementia (n = 32) were recruited in intervention (n = 18) and control (n = 14) homes. Informal carers (total, n = 12: intervention, n = 5; control, n = 7) and 97 staff from eight sites (intervention, n = 75; control, n = 22) were recruited over a 6-month period. Recruitment is feasible. Completion rates of the primary outcome questionnaires were high at baseline (100%) and at 4 weeks (96.8%). The Quality of Life in Late Stage Dementia was more responsive to change over 24 weeks. Even where economic data were missing, these could be collected in a full trial. The intervention was acceptable; the dose varied depending on the staffing and physical environment of each care home. Staff and informal carers reported changes for the person with dementia in two ways: increased social engagement and greater calm. No adverse events related to the intervention were reported.

CONCLUSIONS

A subsequent definitive trial is feasible if there are amendments to the recruitment process, outcome measure choice and intervention specification.

FUTURE WORK

In a full trial, consideration is needed of the appropriate outcome measure that is sensitive to different participant responses, and of clear implementation principles for this person-centred intervention in a nursing home context.

Appropriate frameworks for economic evaluation of end of life care: A qualitative investigation with stakeholders

BACKGROUND

The use of quality-adjusted life years rests on the assertion that the objective of the health care system is to improve health.

AIM

To elicit the views of expert stakeholders on the purpose and evaluation of supportive end of life care, and explore how different purposes of end of life care imply the need for different evaluative frameworks.

DESIGN

Semi-structured qualitative interviews, analysed through an economic lens using a constant comparative approach.

PARTICIPANTS

Twenty professionals working in or visiting the United Kingdom or Republic of Ireland, with clinical experience and/or working as academics in health-related disciplines.

RESULTS

Four purposes of end of life care were identified from and are critiqued with the aid of the qualitative data: to improve health, to enable patients to die in their preferred place, to enable the patient to experience a good death, and to enable the patient to experience a good death, and those who are close to the patient to have an experience which is as free as possible from fear, stress and distress.

CONCLUSION

Managing symptoms and reducing anxiety were considered to be core objectives of end of life care and fit with the wider health service objective of improving/maximising health. A single objective across the entire health system ensures consistency in the way that resource allocation is informed across that entire system. However, the purpose of care at the end of life is more complex, encompassing diverse and patient-centred objectives which we have interpreted as enabling the patient to experience a good death.

"What's fair to an individual is not always fair to a population": A qualitative study of patients and their health professionals using the Cancer Drugs Fund

OBJECTIVE

To understand the values attached to cancer treatment at the end of life (EoL) to inform policy decisions around the Cancer Drugs Fund (CDF) and the National Institute for Health and Care Excellence (NICE) EoL criterion.

DESIGN

Semi-structured interviews with patients and health professionals. Purposive recruitment was performed iteratively alongside analysis of interview transcripts using constant comparison.

PARTICIPANTS

Patients with incurable prostate and colorectal cancer (n = 22) who received drugs funded through the CDF and oncologists and palliative care professionals (n = 16) treating patients on CDF drugs.

RESULTS

While the majority of patient and oncologist participants expressed gratitude for access to the CDF, some patient participants reported experiencing a sense of guilt, and many oncologists admitted to concern about the justice of a ring-fenced fund solely for anti-cancer drugs. For patient and professional participants, cancer drugs were not necessarily seen as a funding priority over other calls on the NHS purse. Overall, patients and health professionals emphasised prioritising quality over quantity at the end of life, with only a minority describing improved quality of life at the end of life which added value.

CONCLUSION

While patients and oncologists appreciated the drugs available through the CDF, most expressed concern about its fairness. Competing participant views about the added value of the end of life is challenging for resource allocation.

ICECAP-O, the current state of play: a systematic review of studies reporting the psychometric properties and use of the instrument over the decade since its publication

PURPOSE

A paper reporting the development of the ICECAP-O was published in 2006. Since then, there has been increasing interest in the use of capability-based measures within health economics and the ICECAP-O has been suggested for use in economic evaluation by decision-making bodies in the Netherlands and UK.

METHODS

A systematic review of studies published between January 2006 and October 2018 which have assessed the psychometric properties of ICECAP-O or utilised the measure within economic evaluation.

RESULTS

Twenty-four studies explored the psychometric properties of ICECAP-O and 21 have utilised the measure within economic evaluation; one study reported psychometric properties as well as utilising the measure within economic evaluation. The ICECAP-O has good construct validity and responsiveness, but there is evidence of some issues relating to content validity. In the context of economic evaluation, the ICECAP-O has, to date, mainly been included as a secondary economic measure and the reporting of results is brief with minimal detail and often no discussion. Five of the economic evaluation studies combined scores from ICECAP-O with time, but each used different terminology to describe this result.

CONCLUSION

Focus, in terms of publications, appears to have shifted now from assessment of psychometric properties to the utilisation of the ICECAP-O within economic evaluation. Further research is needed with respect to a decision-rule for the ICECAP measures. This additional research should also guide users in terms of appropriate analysis, terminology and presentation of results, which are in-keeping with the conceptual framework underpinning the ICECAP-O.

Adaptation, Acceptance and Adaptive Preferences in Health and Capability Well-Being Measurement Amongst Those Approaching End of Life

BACKGROUND AND OBJECTIVES

Adaptive preferences occur when people subconsciously alter their views to account for the possibilities available to them. Adaptive preferences may be problematic where these views are used in resource allocation decisions because they may lead to underestimation of the true benefits of providing services. This research explored the nature and extent of both adaptation (changing to better suit the context) and adaptive preferences (altering preferences in response to restricted options) in individuals approaching the end of life (EoL).

METHODS

Qualitative data from 'thinkaloud' interviews with 33 hospice patients, 22 close persons and 17 health professionals were used alongside their responses to three health/well-being measures for use in resource allocation decisions: EQ-5D-5L (health status); ICECAP-A (adult capability); and ICECAP-SCM (Supportive Care Measure; EoL capability). Constant comparative analysis combined a focus on both verbalised perceptions across the three groups and responses to the measures.

RESULTS

Data collection took place between October 2012 and February 2014. Informants spoke clearly about how patients had adapted their lives in response to symptoms associated with their terminal condition. It was often seen as a positive choice to accept their state and adapt in this way but, at the same time, most patients were fully aware of the health and capability losses that they had faced. Self-assessments of health and capability generally appeared to reflect the pre-adaptation state, although there were exceptions.

CONCLUSION

Despite adapting to their conditions, the reference group for individuals approaching EoL largely remained a healthy, capable population, and most did not show evidence of adaptive preferences.

Hospice patients' participation in choice experiments to value supportive care outcomes

BACKGROUND

Values used in economic evaluation are typically obtained from the general public, which is problematic when measures are to be used with people experiencing a life-course stage such as the end of life.

OBJECTIVE

To assess the feasibility of obtaining values for the ICECAP-Supportive Care Measure (SCM) from patients receiving advanced supportive care through a hospice.

METHODS

Participants completed eight best-worst scaling questions in a think-aloud interview to explain choices in different hypothetical end-of-life scenarios. Three independent raters identified errors in completion of the best-worst scaling task, and thematic analysis of associated qualitative data was undertaken to explore task difficulty and choices.

RESULTS

Twelve hospice patients were recruited. Most were able to complete the task and prioritise aspects of supportive care with either no difficulty (n=50%) or difficulty in just one of the eight scenarios (n=25%). Two patients (n=17%) were unable to comprehend the hypothetical nature of the task. The qualitative data confirmed there was good engagement with the task and identified the importance the respondents attached to maintaining dignity.

CONCLUSION

The findings suggest that people at the end of life will be able to complete a short, interviewer-administered, best-worst scaling task. To maximise engagement, it is recommended that the task is short and initiated with an example. Scenarios are best presented on show-cards in large print. A full evaluation of the ICECAP-SCM with those at the end of life is feasible.

Development of a Patient-Reported Palliative Care-Specific Health Classification System: The POS-E

Background

Generic preference-based measures are commonly used to estimate quality-adjusted life-years (QALYs) to inform resource-allocation decisions. However, concerns have been raised that generic measures may be inappropriate in palliative care.

Objective

Our objective was to derive a health-state classification system that is amenable to valuation from the ten-item Palliative Care Outcome Scale (POS), a widely used patient-reported outcome measure in palliative care.

Methods

The dimensional structure of the original POS was assessed using factor analysis. Item performance was assessed, using Rasch analysis and psychometric criteria, to enable the selection of items that represent the dimensions covered by the POS. Data from six studies of patients receiving palliative care were combined (N = 1011) and randomly split into two halves for development and validation. Analysis was undertaken on the development data, and results were validated by repeating the analysis with the validation dataset.

Results

Following Rasch and factor analyses, a classification system of seven items was derived. Each item had two to three levels. Rasch threshold map helped identify a set of 14 plausible health states that can be used for the valuation of the instrument to derive a preference-based index.

Conclusion

Combining factor analysis and Rasch analysis with psychometric criteria provides a valid method of constructing a classification system for a palliative care-specific preference-based measure. The next stage is to obtain preference weights so the measure can be used in economic evaluations in palliative care.

Adaptation and assessments of the Chinese version of the ICECAP-A measurement

BACKGROUND

This study adapts the ICECAP measure for Adults (ICECAP-A) to assess its capacity to measure the quality of life in China for economic evaluation.

METHODS

Qualitative and quantitative methods were used to translate the ICECAP-A measure for wellbeing, established by the University of Birmingham, UK, to the Chinese cultural context. A focus group discussion solved the appropriateness and wording of the ICECAP attributes in Chinese; and a randomly selected sample of 1000 adults aged over 18 years were online surveyed. We conducted psychometric tests and compared the factors influencing the ICECAP-A measure with those influencing EQ-5D-3 L.

RESULTS

Members of the focus group discussion agreed that the five attributes of the ICECAP-A measure are sufficient to evaluate wellbeing in China. However, the terms "being settled" and "friendship" were changed to "stability" and "kindness" for the Chinese cultural context. Our results show that the Chinese version of ICECAP-A has good internal consistency with an overall Cronbach's Alpha coefficient of 0.7999. The concurrent validity indicates that ICECAP-A is moderately correlated with EQ-5D-3 L (r ≤ 0.52).

CONCLUSIONS

The ICECAP-A measure can be adapted to evaluate wellbeing in China, but cultural changes to the wording are necessary. It is a valid measurement of wellbeing and can complement the EQ-5D already used in China. However, further work is still needed to evaluate the sensitivity of the ICECAP-A measure in relation to public health and social care.

Do capability and functioning differ? A study of U.K. survey responses

A core feature of the capability approach is that a person's capabilities (what they are able to do and be in their life) can differ from their functionings (what they actually do and are in their life). However, the degree to which capability and functioning differ in practice is unclear. This paper investigates this issue, focusing on capability and functioning differences (CFD) across different aspects of life and different individuals. In the study, the ICECAP-A capability questionnaire was modified to measure both functionings and capabilities and was completed by U.K.-based convenience sample of 943 people. Around one third of people reported CFD in at least one area of their life, most commonly in terms of their "achievement." People were more likely to report CFD when they had a degree-level education and when they had impaired health. An additional finding was that capability varied more with education whereas functioning varied more with health status. This finding needs further examination, but it suggests that the choice of evaluative space may influence how priorities are set for public spending.

Assessing the capability to experience a 'good death': A qualitative study to directly elicit expert views on a new supportive care measure grounded in Sen's capability approach

BACKGROUND

Sen's capability approach is underspecified; one decision left to those operationalising the approach is how to identify sets of relevant and important capabilities. Sen has suggested that lists be developed for specific policy or research objectives through a process of public reasoning and discussion. Robeyns offers further guidance in support of Sen's position, suggesting that lists should be explicit, discussed and defended; methods be openly scrutinised; lists be considered both in terms of what is ideal and what is practical ('generality'); and that lists be exhaustive. Here, the principles suggested by Robeyns are operationalised to facilitate external scrutiny of a list of capabilities identified for use in the evaluation of supportive end of life care.

METHODS

This work started with an existing list of seven capabilities (the ICECAP-SCM), identified as being necessary for a person to experience a good death. Semi-structured qualitative interviews were conducted with 20 experts in economics, psychology, ethics and palliative care, to facilitate external scrutiny of the developed list. Interviews were recorded, transcribed and analysed using constant comparison.

RESULTS

The seven capabilities were found to encompass concepts identified as important by expert stakeholders (to be exhaustive) and the measure was considered feasible for use with patients receiving care at the end of life.

CONCLUSION

The rigorous development of lists of capabilities using both initial participatory approaches with affected population groups, and subsequent assessment by experts, strengthens their democratic basis and may encourage their use in policy contexts.

An Investigation of the Overlap Between the ICECAP-A and Five Preference-Based Health-Related Quality of Life Instruments

BACKGROUND

The ICEpop CAPability measure for Adults (ICECAP-A) is a measure of capability wellbeing developed for use in economic evaluations. It was designed to overcome perceived limitations associated with existing preference-based instruments, where the explicit focus on health-related aspects of quality of life may result in the failure to capture fully the broader benefits of interventions and treatments that go beyond health. The aim of this study was to investigate the extent to which preference-based health-related quality of life (HRQoL) instruments are able to capture aspects of capability wellbeing, as measured by the ICECAP-A.

METHODS

Using data from the Multi Instrument Comparison project, pairwise exploratory factor analyses were conducted to compare the ICECAP-A with five preference-based HRQoL instruments [15D, Assessment of Quality of Life 8-dimension (AQoL-8D), EQ-5D-5L, Health Utilities Index Mark 3 (HUI-3), and SF-6D].

RESULTS

Data from 6756 individuals were used in the analyses. The ICECAP-A provides information above that garnered from most commonly used preference-based HRQoL instruments. The exception was the AQoL-8D; more common factors were identified between the ICECAP-A and AQoL-8D compared with the other pairwise analyses.

CONCLUSION

Further investigations are needed to explore the extent and potential implications of 'double counting' when applying the ICECAP-A alongside health-related preference-based instruments.

Development of a measure (ICECAP-Close Person Measure) through qualitative methods to capture the benefits of end-of-life care to those close to the dying for use in economic evaluation

BACKGROUND

End-of-life care affects both the patient and those close to them. Typically, those close to the patient are not considered within economic evaluation, which may lead to the omission of important benefits resulting from end-of-life care.

AIM

To develop an outcome measure suitable for use in economic evaluation that captures the benefits of end-of-life care to those close to the dying.

DESIGN

To develop the descriptive system for the outcome measure, in-depth qualitative interviews were conducted with the participants and constant comparative analysis methods were used to develop a descriptive system for the measure.

PARTICIPANTS

Twenty-seven individuals bereaved within the last 2 years or with a close-person currently receiving end-of-life care were purposively recruited into the study. Participants were recruited through newsletters, adverts, snowball sampling and a local hospice.

RESULTS

Twenty-seven individuals were recruited. A measure of capability with six attributes, each with five levels, was developed based on themes arising from the analysis. Attributes comprise the following: good communication with services, privacy and space to be with the loved one, emotional support, practical support, being able to prepare and cope and being free from emotional distress related to the condition of the decedent.

CONCLUSION

This measure is designed to capture the benefits of end-of-life care to close-persons for use in economic evaluation. Further research should value the measure and develop methods for incorporating outcomes for close-persons into economic evaluation.
