Moving Beyond the QALY: Economic Evaluation in Health and Social Care for Elderly Populations

__Abstract__ The growing number of elderly consumes an increasing amount of health and social care services, straining public budgets. Economic evaluations have traditionally focused on curative care using health-related quality of life as outcomes, and gave answers which interventions to fund or not to fund. However in order to evaluate long-term care as well, broader outcomes are necessary. The aim of this thesis is to address a number of issues related to outcome measurement in economic evaluations in elderly populations consuming health and social care. After performing a traditional economic evaluation in long-term care and identifying the limitations, a systematic review was performed in order to search for more appropriate outcomes. The review identified the ICECAP-O instrument, and this has been validated in Dutch and German Nursing homes, as well as in a population of post-hospitalized older people. Finally, we have performed an economic evaluation using the ICECAP-O. The ICECAP-O in general measures broader than health outcomes. It was related to measures of health-related and dementia-specific quality of life, physical, mental and social health, and to wellbeing instruments. It also differentiates between elderly below and above 75 years, multimorbidity, dementia severity, living alone or together and elderly with nursing homes with or without physical restraints. In

Cost-effectiveness of a pressure ulcer quality collaborative

ABSTRACT. BACKGROUND: A quality improvement collaborative (QIC) in the Dutch long-term care sector (nursing homes, assisted living facilities, home care) used evidence-based prevention methods to reduce the incidence and prevalence of pressure ulcers (PUs). The collaborative consisted of a core team of experts and 25 organizational project teams. Our aim was to determine its cost-effectiveness from a healthcare perspective. METHODS: We used a non-controlled pre-post design to establish the change in incidence and prevalence of PUs in 88 patients over the course of a year. Staff indexed data and prevention methods (activities, materials). Quality of life (Qol) weights were assigned to the PU states. We assessed the costs of activities and materials in the project. A Markov model was built based on effectiveness and cost data, complemented with a probabilistic sensitivity analysis. To illustrate the results of longer term, three scenarios were created in which change in incidence and prevalence measures were (1) not sust

Quality of life of nursing home residents with dementia: Validation of the German version of the ICECAP-O

Objectives: To validate the ICECAP-O capability wellbeing measure's German translation in older people with dementia living in a nursing home, and to investigate the influence of proxy characteristics on responses. Method: Cross-sectional study. For 95 residents living in a German nursing home, questionnaires were completed by nursing professionals serving as proxy respondents. We investigated the convergent validity of the ICECAP-O with other Quality of Life (Qol) measures, the EQ-5D extended with a cognitive dimension (EQ-5D+C), the Alzheimer's Disease Related Quality of Life (ADRQL) measures, and the Barthel-index measure of Activities of Daily Living (ADL). Discriminant validity was investigated using bivaria

Examining the construct and known-group validity of a composite endpoint for the Older Persons and Informal Caregivers Survey Minimum Data Set (TOPICS-MDS); A largescale data sharing initiative

Background Preference-weighted multi-faceted endpoints have the potential to facilitate comparative effectiveness research that incorporates patient preferences. The Older Persons and Informal Caregivers Survey Composite endpoint (TOPICS-CEP) is potentially a valuable outcome measure for evaluating interventions in geriatric care as it combines multiple outcomes relevant to older persons in a single metric. The objective of this study was to validate TOPICS-CEP across different study settings (general population, primary care and hospital). Methods Data were extracted from TOPICS Minimum Dataset (MDS), a pooled public-access national database with information on older persons throughout the Netherlands. Data of

Capabilities and quality of life in Dutch psycho-geriatric nursing homes: an exploratory study using a proxy version of the ICECAP-O

Contains fulltext : 110478.pdf (publisher's version ) (Open Access)PURPOSE: To validate the ICECAP-O capability measure in psycho-geriatric elderly in nursing homes, we compared the capability scores of restrained and unrestrained clients. Both nursing staff and family were used as proxies for assessing clients' capabilities. METHOD: For 122 psycho-geriatric elderly, a total of 96 nursing professionals and 68 family members completed a proxy questionnaire. We investigated the convergent and discriminant validity of the ICECAP-O and measures of care dependency, health-related quality of life, and overall quality of life. We also directly compared ICECAP-O scores of the 56 clients for whom both nursing staff and family members had completed the questionnaire. RESULTS: Convergent validity between ICECAP-O and care dependency, health-related, and overall quality of life measures could be established, as well as discriminant validity for the restrained and unrestrained groups. Nursing and family proxy ICECAP-O tariffs were not significantly correlated. DISCUSSION: ICECAP-O measures a more general concept than health-related quality of life and can differentiate between restrained and non-restrained psycho-geriatric clients. Since nurses seem to be able to assess the current quality of life of clients using the ICECAP-O more precisely than the family proxies, for now the use of nursing proxies is recommended in a nursing home setting
