An assessment of the construct validity of the ASCOT measure of social care-related quality of life with older people

BackgroundThe adult social care outcomes toolkit (ASCOT) includes a preference-weighted measure of social care-related quality of life for use in economic evaluations. ASCOT has eight attributes: personal cleanliness and comfort, food and drink, control over daily life, personal safety, accommodation cleanliness and comfort, social participation and involvement, occupation and dignity. This paper aims to demonstrate the construct validity of the ASCOT attributes.MethodsA survey of older people receiving publicly-funded home care services was conducted by face-to-face interview in several sites across England. Additional data on variables hypothesised to be related and unrelated to each of the attributes were also collected. Relationships between these variables and the attributes were analysed through chi-squared tests and analysis of variance, as appropriate, to test the construct validity of each attribute.Results301 people were interviewed and approximately 10% of responses were given by a proxy respondent. Results suggest that each attribute captured the extent to which respondents exercised choice in how their outcomes were met. There was also evidence for the validity of the control over daily life, occupation, personal cleanliness and comfort, personal safety, accommodation cleanliness and comfort, and social participation and involvement attributes. There was less evidence regarding the validity of the food and drink and dignity attributes, but this may be a consequence of problems finding good data against which to validate these attributes, as well as problems with the distribution of the food and drink item.ConclusionsThis study provides some evidence for the construct validity of the ASCOT attributes and therefore support for ASCOTs use in economic evaluation. It also demonstrated the feasibility of its use among older people, although the need for proxy respondents in some situations suggests that developing a version that is suitable for proxies would be a useful future direction for this work. Validation of the instrument on a sample of younger social care users would also be useful.

Care by Spouses, Care by Children: Projections of Informal Care for Older People in England to 2031

The future market costs of long-term care for older people will be affected by the extent of informal care. This paper reports on projections of receipt of informal care by disabled older people from their spouses and (adult) children to 2031 in England. The paper shows that, over the next 30 years, care by spouses is likely to increase substantially. However, if current patterns of care remain the same, care by children will also need to increase by nearly 60 per cent by 2031. It is not clear that the supply of care by children will rise to meet this demand.

Measuring Quality in Social Care Services: Theory and Practice

Measuring and assessing service quality in the social care sector presents distinct challenges. The ‘experience’ good properties of social care, for instance, and the large influence played by subjective judgements about the quality of personal relationships between carer and user and of process-related service characteristics make it difficult to develop indicators of service quality, including those of service impact on final outcomes. Using some of the key features of the ‘Production of Welfare’ approach, the paper discusses recent developments in the UK of the theoretical and practical frameworks used for assessing quality in social care and for understanding the final impact of services on the wellbeing of their recipients. Key current and future challenges to the development of such frameworks include difficulties in disentangling the impact of social care services on final outcomes from the often dominating effects of other, non-service related factors, and the generalization of consumer-directed care models and of the ‘personalization’ of care services. These challenges are discussed in the context of the different possible applications of quality indicators, including their role as supporting the service commissioning process and their use for assessing the performance of service providers.

Winners and losers: assessing the distributional effects of long-term care funding regimes

Using two linked simulation models, we examine the public expenditure costs and distributional effects of potential reforms to long-term care funding in the UK. Changes to the means tests for user contributions to care costs are compared with options for the abolition of these means tests (‘free’ personal care). The latter generally cost more than the former and benefit higher income groups more than those on lower incomes (measuring income in relation to the age-specific income distribution). Reforms to the means tests target benefits towards those on lower incomes. However, the highest income group are net losers if free personal care is financed by a higher tax rate on higher incomes and the effect on the whole population considered.

Using cost-effectiveness estimates from survey data to guide commissioning: an application to home care

The aim is to describe and trial a pragmatic method to produce estimates of the incremental cost-effectiveness of care services from survey data. The main challenge is in estimating the counterfactual; that is, what the patients quality of life would be if they did not receive that level of service. A production function method is presented, which seeks to distinguish the variation in care-related quality of life in the data that is due to service use as opposed to other factors. A problem is that relevant need factors also affect the amount of service used and therefore any missing factors could create endogeneity bias. Instrumental variable estimation can mitigate this problem. This method was applied to a survey of older people using home care as a proof of concept. In the analysis, we were able to estimate a quality-of-life production function using survey data with the expected form and robust estimation diagnostics. The practical advantages with this method are clear, but there are limitations. It is computationally complex, and there is a risk of misspecification and biased results, particularly with IV estimation. One strategy would be to use this method to produce preliminary estimates, with a full trial conducted thereafter, if indicated.

Mapping the future of family care: receipt of informal care by older people with disabilities in England to 2032

Many long-term care systems in economically developed countries are reliant on informal care. However, in the context of population ageing, there are concerns about the future supply of informal care. This article reports on projections of informal care receipt by older people with disabilities from spouses and (adult) children to 2032 in England. The projections show that the proportions of older people with disabilities who have a child will fall by 2032 and that the extent of informal care in future may be lower than previously estimated. The policy implications, in the context of the Dilnot Commissions report, are explored.

What can local authorities do to improve the social care-related quality of life of older adults living at home? Evidence from the Adult Social Care Survey

Local authorities spend considerable resources on social care at home for older adults. Given the expected growth in the population of older adults and budget cuts on local government, it is important to find efficient ways of maintaining and improving the quality of life of older adults. The ageing in place literature suggests that policies in other functions of local authorities may have a significant role to play. This study aims to examine the associations between social care-related quality of life (SCRQoL) in older adults and three potential policy targets for local authorities: (i) accessibility of information and advice, (ii) design of the home and (iii) accessibility of the local area. We used cross-sectional data from the English national Adult Social Care Survey (ASCS) 2010/2011 on service users aged 65 years and older and living at home (N=29,935). To examine the association between SCRQoL, as measured by the ASCOT, and three single-item questions about accessibility of information, design of the home and accessibility of the local area, we estimate linear and quantile regression models. After adjusting for physical and mental health factors and other confounders our findings indicate that SCRQoL is significantly lower for older adults who find it more difficult to find information and advice, for those who report that their home design is inappropriate for their needs and for those who find it more difficult to get around their local area. In addition, these three variables are as strongly associated with SCRQoL as physical and mental health factors. We conclude that in seeking to find ways to maintain and improve the quality of life of social care users living at home, local authorities could look more broadly across their responsibilities. Further research is required to explore the cost-effectiveness of these options compared to standard social care services.

Measuring and monitoring outputs in social care: the problem of measuring quality

The focus of this article is the measurement of quality within the context of a new approach to measuring government-funded social care services. The approach builds on principles set out in a UK review led by Professor Sir Tony Atkinson. At its heart are the concepts of capacity for benefit, describing the potential benefit to users from services, and quality, reflecting the extent to which the benefit is realized. We report on a study designed to explore the suitability of a weighted user satisfaction measure to measure quality, examining in particular its sensitivity to changes in the quality of social care over time. The study finds some problems with using weighted user satisfaction. We discuss potential reasons for these problems, including the possibility of gaming and the specification of the measure, and discuss a way forward in the context of the requirement to draw upon routine sources of data. Points for practitioners The article describes a practical approach to measuring and monitoring outcomes and productivity in social care. Routine measures are used as far as possible, weighted to reflect outcomes for services users. The concepts of Capacity for Benefit and quality in this context potentially allow commissioners and managers to distinguish the impact on productivity of: the potential of services as they are currently configured, the dependency of service users, and the quality of delivery. The article identifies key issues and problems in using measures of satisfaction both as performance indicators and monitoring quality of services in the proposed approach.

The effect of lengthening Life Expectancy on future pension and Long-Term Care expenditure in England, 2007 to 2032

AbstractBackground The aim of this analysis is to examine the effect of different assumptions about future trends in life expectancy (LE) on the sustainability of the pensions and long-term care (LTC) systems. The context is the continuing debate in England about the reform of state pensions and the reform of the system for financing care and support. Methods Macro and micro simulation models are used to make projections of future public expenditure on LTC services for older people and on state pensions and related benefits, making alternative assumptions on increases in future LE. The projections cover the period 2007 to 2032 and relate to England. Results Results are presented for a base case and for specified variants to the base case. The base case assumes that the number of older people by age and gender rises in line with the Office for National Statistics’ principal 2006-based population projection for England. It also assumes no change in disability rates, no changes in patterns of care, no changes in policy and rises in unit care costs and real average earnings by 2 per cent per year. Under these assumptions public expenditure on pensions and related benefits is projected to rise from 4.7 per cent of Gross Domestic Product (GDP) in 2007 to 6.2 per cent of GDP in 2032 and public expenditure on LTC from 0.9 per cent of GDP in 2007 to 1.6 per cent of GDP in 2032. Under a very high LE variant to the GAD principal projection, however, public expenditure on pensions and related benefits is projected to reach 6.8 per cent of GDP in 2032 and public expenditure on LTC 1.7 per cent of GDP in 2032. Conclusions MPolicymakers developing reform proposals need to recognise that, since future LE is inevitably uncertain and since variant assumptions about future LE significantly affect expenditure projections, there is a degree of uncertainty about the likely impact of demographic pressures on future public expenditure on pensions and LTC.

The factors associated with care-related quality of life of adults with intellectual disabilities in England: implications for policy and practice.

Abstract Over the last three decades, quality of life (QoL) has been advocated as an indicator of social care outcomes for adults with intellectual disabilities. In England, the Adult Social Care Survey (ASCS) is conducted annually by local authorities to contribute to the evidence base of the care‐related QoL of people receiving publicly funded adult social care. This study explores relationships between QoL and non‐care‐related factors to identify relationships that could inform social care policy and practice. Cross‐sectional data collected from 13,642 adults who participated in the 2011 and 2012 ASCS were analysed using regression to explore the factors associated with QoL measured using the Adult Social Care Outcomes Toolkit (ASCOT). Self‐rated health, rating of the suitability of home design and anxiety/depression were all found to be significantly associated with ASCOT. Other individual and survey completion factors were also found to have weak significant relationships with ASCOT. The models also indicate that there was an increase in overall ASCOT‐QoL and in five of the eight ASCOT domains (Personal comfort and cleanliness, Safety, Social participation, Occupation and Dignity) between 2011 and 2012. These findings demonstrate the potential value of QoL data for informing policy for people with intellectual disabilities by identifying key factors associated with QoL, the characteristics of those at risk of lower QoL, and QoL domains that could be targeted for improvement over time. Future research should establish causal relationships and explore the risk adjustment of scores to account for variation outside of the control of social care support.
