Abstract
Objectives: Aotearoa New Zealand has demonstrable maternal and perinatal health inequity.
We examined the relationships between adverse outcomes in a total population
sample of births and a range of social determinant variables representing
barriers to equity. Methods: Using the Statistics New Zealand Integrated Data Infrastructure suite of
linked administrative data sets, adverse maternal and perinatal outcomes
(mortality and severe morbidity) were linked to socio-economic and health
variables for 97% of births in New Zealand between 2003 and 2018 (~970,000
births). Variables included housing, economic, health, crime and family
circumstances. Logistic regression examined the relationships between
adverse outcomes and social determinants, adjusting for demographics
(socio-economic deprivation, education, parity, age, rural/urban residence
and ethnicity). Results: Māori (adjusted odds ratio = 1.21, 95% confidence interval = 1.18–1.23) and
Asian women (adjusted odds ratio 1.39, 95% confidence interval = 1.36–1.43)
had poorer maternal or perinatal outcomes compared to New Zealand
European/European women. High use of emergency department (adjusted odds
ratio = 2.68, 95% confidence interval = 2.53–2.84), disability (adjusted
odds ratio = 1.98, 95% confidence interval = 1.83–2.14) and lack of
engagement with maternity care (adjusted odds ratio = 1.89, 95% confidence
interval = 1.84–1.95) had the strongest relationship with poor outcomes. Conclusion: Maternal health inequity was strongly associated with a range of
socio-economic and health determinants. While some of these factors can be
targeted for interventions, the study highlights larger structural and
systemic issues that affect maternal and perinatal health.

Challenges in developing capability measures for children and young people for use in the economic evaluation of health and care interventions. HEALTH ECONOMICS 2021; 30:1990-2003. [PMID: 34036671 PMCID: PMC7614859 DOI: 10.1002/hec.4363] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 05/13/2021] [Accepted: 05/14/2021] [Indexed: 05/26/2023]
Abstract
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.

Abstract
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.

Abstract
Background The purpose of this review was to examine the literature for themes of underlying social contributors to inequity in maternal health outcomes and experiences in the high resource setting of Aotearoa New Zealand. These ‘causes of the causes’ were explored and compared with the international context to identify similarities and New Zealand-specific differences. Method A structured integrative review methodology was employed to enable a complex cross disciplinary analysis of data from a variety of published sources. This method enabled incorporation of diverse research methodologies and theoretical approaches found in the literature to form a unified overall of the topic. Results Six integrated factors – Physical Access, Political Context, Maternity Care System, Acceptability, Colonialism, and Cultural factors – were identified as barriers to equitable maternal health in Aotearoa New Zealand. The structure of the maternal health system in New Zealand, which includes free maternity care and a woman centred continuity of care structure, should help to ameliorate inequity in maternal health and yet does not appear to. A complex set of underlying structural and systemic factors, such as institutionalised racism, serve to act as barriers to equitable maternity outcomes and experiences. Initiatives that appear to be working are adapted to the local context and involve self-determination in research, clinical outreach and community programmes. Conclusions The combination of six social determinants identified in this review that contribute to maternal health inequity is specific to New Zealand, although individually these factors can be identified elsewhere; this creates a unique set of challenges in addressing inequity. Due to the specific social determinants in Aotearoa New Zealand, localised solutions have potential to further maternal health equity.

Abstract
Purpose Economic evaluation of services and interventions in care services tends to focus on quality of life(QoL) based on health-related measures such as EQ5D, with a major focus on health and functioning. The Capability Approach (CA) provides an alternative framework for measuring QoL and challenges some of the conventional issues in the current practice of measurement of QoL. The Adult Social Care Outcomes Toolkit (ASCOT) aims to measure social care-related QoL in a broad sense. This article investigates whether and, if so, how the ASCOT addresses issues put on the agenda by the CA. Methods Literature analysis concerning theoretical assumptions and arguments of CA and ASCOT. Results The Capability Approach (CA) puts three issues on the agenda regarding QoL. First, the focus of evaluation should not be on functioning, but on freedom of choice. Second, evaluation should be critical about adaptive preferences, which entail that people lower expectations in situations of limited possibilities. Third, evaluation should not only address health, but also other domains of life. Our analysis shows that freedom of choice is reflected in the response option ‘as I want’ in the ASCOT questionnaire. The problem of adaptive preferences is countered in the ASCOT by developing a standard based on preferences of the general population. Third, the ASCOT contains several domains of life. Conclusions We conclude that the CA and the ASCOT contribute to the discussion on QoL, and that the ASCOT operationalizes core assumptions of the CA, translating the issues raised by the CA in a practical way.

Abstract
BACKGROUND There is a debate in the health economics literature concerning the most appropriate way of applying Amartya Sen's capability approach in economic evaluation studies. Some suggest that quality-adjusted life years (QALYs) alone are adequate while others argue that this approach is too narrow and that direct measures of capability wellbeing provide a more extensive application of Sen's paradigm. OBJECTIVE This paper empirically explores whether QALYs provide a good proxy for individual capabilities. METHODS Data is taken from a multinational cross-sectional survey of individuals with seven health conditions (asthma, arthritis, cancer, depression, diabetes, hearing loss, heart disease) and a healthy population. Each individual completed the ICECAP-A measure of capability wellbeing for adults and six health utility instruments that are used to generate QALYs, including EQ-5D and SF-6D. Primary analysis examines how well health utility instruments can explain variation in the ICECAP-A using ordinary least squares regression. RESULTS The findings show that all seven health conditions have a negative association on overall capability as measured by the ICECAP-A index. Inclusion of health utility instruments into separate regressions improves the predictive power of capability but on average, explains less than half of the variation in capability wellbeing. Individuals with arthritis appear to be less inhibited in terms of capability losses when accounting for health utility, yet those who have depression record significant reductions in capability relative to the healthy population even after accounting for the most commonly used health utility instruments. CONCLUSION The study therefore casts doubt on the ability of QALYs to act as a reliable proxy measure of individuals' capability.

Abstract
Standard indicators of wellbeing such as the QALY for health and GDP per capita for economic development have been increasingly regarded as being too narrow in focus. There is a need to develop multidimensional measures of wellbeing that encompass the full range of factors that make life worth living. This study is part of a project that aims at developing a multidimensional index based on Sen's capability framework to assess women's wellbeing in rural Malawi: the Women's Capabilities Index. The project identifies a set of capabilities relevant to the context; proposes a methodology to measure robustly these capabilities; aggregates the capabilities into a single metric (index); and validates and tests the index. This paper focuses on the weighting and aggregation of the index. Four weighting methods of aggregation are chosen: two normative approaches; a data-driven approach; and a hybrid method. The different methods have implications on the results which are critically assessed and compared. This study contributes to the literature on the implications of adopting different methods for setting the weights in composite measures of wellbeing.

Abstract
Recent years have seen increased engagement amongst health economists with the capability approach developed by Amartya Sen and others. This paper focuses on the capability approach in relation to the evaluative space used for analysis within health economics. It considers the opportunities that the capability approach offers in extending this space, but also the methodological challenges associated with moving from the theoretical concepts to practical empirical applications. The paper then examines three 'families' of measures, Oxford Capability instruments (OxCap), Adult Social Care Outcome Toolkit (ASCOT) and ICEpop CAPability (ICECAP), in terms of the methodological choices made in each case. The paper concludes by discussing some of the broader issues involved in making use of the capability approach in health economics. It also suggests that continued exploration of the impact of different methodological choices will be important in moving forward.

Abstract
In the aftermath of the economic crisis that started in 2008, resources have become scarcer than ever in some countries, also in health care. Priority setting and rationalisation of existing resources also affect pharmaceutical innovations, including those that would contribute to what is called personalised medicine. In this paper, we will highlight the ethical issues surrounding rationalisation and its impact on personalised medicine through the lens of the capability approach. Thereby, challenges to and opportunities for personalised medicine will be examined, assessing how they affect patients' 'real options' to access innovative therapies. In our focus on the 'first challenge: citizens and patients' of the so-called Strategic Research and Innovation Agenda, the strength of the capability approach becomes particularly apparent in identifying what different values are at stake in this context.

Abstract
Amartya Sen's capability approach has been discussed widely in the health economics discipline. Although measures have been developed to assess capability in economic evaluation, there has been much less attention paid to the decision rules that might be applied alongside. Here, new methods, drawing on the multidimensional poverty and health economics literature, are developed for conducting economic evaluation within the capability approach and focusing on an objective of achieving "sufficient capability". This objective more closely reflects the concern with equity that pervades the capability approach and the method has the advantage of retaining the longitudinal aspect of estimating outcome that is associated with quality-adjusted life years (QALYs), whilst also drawing on notions of shortfall associated with assessments of poverty. Economic evaluation from this perspective is illustrated in an osteoarthritis patient group undergoing joint replacement, with capability wellbeing assessed using ICECAP-O. Recommendations for taking the sufficient capability approach forward are provided.

Abstract
Background. There is a growing interest in the application of the capability approach in health economic analysis. The aim of the research reported here is to assess the feasibility of mapping from a condition-specific questionnaire (Western Ontario and McMaster Universities [WOMAC] Osteoarthritis Index) to a capability well-being questionnaire (ICEpop CAPability measure for Older people [ICECAP-O]). Methods. One hundred five osteoarthritis patients requiring joint replacement completed the 5 attributes on the ICECAP-O (attachment, security, role, enjoyment, and control) and the 3 WOMAC categories (pain, stiffness, and physical function). The prediction data set consisted of baseline scores, whereas follow-up data were used to validate the predictions. The mapping algorithms used ordinary least squares and multinomial logistic regression models to predict the relationship between WOMAC scores, categories, or items and ICECAP-O scores or the 5 ICECAP-O attributes. Results. ICECAP-O scores predicted from WOMAC category scores produced the lowest mapping error statistics (mean absolute error = 0.0832; mean squared error = 0.0142) as well as highest goodness of fit (R2 = 0.3976). Prediction of ICECAP-O attributes from WOMAC category scores was possible for the majority of capability dimensions. The “control” attribute and physical function WOMAC category exhibited the strongest relationship (R2 = 0.2143). The “attachment” attribute proved difficult to predict from any WOMAC category, which is in line with intuition given this attribute captures psychological well-being rather than pain, stiffness, or physical function. Conclusion. This is the first study to investigate the predictive ability of a condition-specific measure of health onto capability. The results presented here suggest it is feasible to map from condition-specific measures to an overall capability index, although WOMAC cannot predict individual capability in its entirety. Although the results here are encouraging for those interested in using ICECAP-O, given the small validation sample size applied, further research will be required to verify these findings.

[PMID: 20623024 PMCID: PMC2898049 DOI: 10.3390/ijerph7052274] [Citation(s) in RCA: 88] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/05/2010] [Revised: 04/30/2010] [Accepted: 05/04/2010] [Indexed: 01/03/2023]
Abstract
Public health interventions have received increased attention from policy makers, and there has been a corresponding increase in the number of economic evaluations within the domain of public health. However, methods to evaluate public health interventions are less well established than those for medical interventions. Focusing on health as an outcome measure is likely to underestimate the impact of many public health interventions. This paper provides a review of outcome measures in public health; and describes the benefits of using the capability approach as a means to developing an all encompassing outcome measure.

Norheim OF, Asada Y. The ideal of equal health revisited: definitions and measures of inequity in health should be better integrated with theories of distributive justice. Int J Equity Health 2009; 8:40. [PMID: 19922612 PMCID: PMC2784761 DOI: 10.1186/1475-9276-8-40] [Citation(s) in RCA: 90] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2009] [Accepted: 11/18/2009] [Indexed: 11/30/2022] Open
Abstract
The past decade witnessed great progress in research on health inequities. The most widely cited definition of health inequity is, arguably, the one proposed by Whitehead and Dahlgren: "Health inequalities that are avoidable, unnecessary, and unfair are unjust." We argue that this definition is useful but in need of further clarification because it is not linked to broader theories of justice. We propose an alternative, pluralist notion of fair distribution of health that is compatible with several theories of distributive justice. Our proposed view consists of the weak principle of health equality and the principle of fair trade-offs. The weak principle of health equality offers an alternative definition of health equity to those proposed in the past. It maintains the all-encompassing nature of the popular Whitehead/Dahlgren definition of health equity, and at the same time offers a richer philosophical foundation. This principle states that every person or group should have equal health except when: (a) health equality is only possible by making someone less healthy, or (b) there are technological limitations on further health improvement. In short, health inequalities that are amenable to positive human intervention are unfair. The principle of fair trade-offs states that weak equality of health is morally objectionable if and only if: (c) further reduction of weak inequality leads to unacceptable sacrifices of average or overall health of the population, or (d) further reduction in weak health inequality would result in unacceptable sacrifices of other important goods, such as education, employment, and social security.

Abstract
This paper explores the spread of ideas within health economics, in relation to the impact of the capability approach to date and the extent to which it might impact in the future. The paper uses UK decision making to illustrate this spread of ideas. Within health economics, Culyer used the capability approach in developing the extra-welfarist perspective (where health status directly influences which social state is preferred). It is not a direct application of capability as the evaluation's focus remains narrow; the concern is with functioning, and maximisation is retained. Culyer's work provided a theoretical basis for using quality-adjusted life-years in decision making and this perspective is accepted as the basis for evaluation by the UK National Institute of Health and Clinical Excellence (NICE). To the extent that extra-welfarism represents a capability approach, capabilities influence NICE's decision making and hence UK health care provision. This paper explores the extent to which extra-welfarism draws on the capability approach; the spread of extra-welfarist ideas; and recent interest in more direct applications of the capability approach.

Abstract
Current UK policy with respect to the provision of health and social care for older people suggests that greater integration is required. Economists' attempts to assist resource allocation decisions, however, are very health focused, with concentration on the use of health-related quality of life measures. This paper reports an attempt to determine attributes for a new index clearly focusing on quality of life for older people rather than health or other influences on quality of life. In-depth interviews were conducted with 40 purposively selected informants aged 65 and over in private households to explore their views about what is important to them in terms of quality of life. Data were analysed using Framework qualitative analysis. Initial discussions tended to concentrate upon factors influencing quality of life including activities, relationships, health, wealth and surroundings. Further probing and analysis suggested five conceptual attributes: attachment, role, enjoyment, security and control. The data also suggested that the quality of informants' lives was limited by the loss of ability to pursue these attributes. So, for example, it is not poor health in itself, which reduces quality of life, but the influence of that poor health upon each informant's ability to, say, be independent, that is important. Amartya Sen's work on functioning and capability is particularly pertinent here. Using this work, it is possible to interpret the five conceptual attributes as a set of functionings-important for older people in the UK in the 21st century-but noting that it is the capacity to achieve these functionings that appears to be of importance. This suggests that further development of this measure should focus on an index of capability rather than preference-based utility.
