Abstract
European countries more than ever face shifts towards aging societies with accompanying challenges for health and aged care services. Economic evaluation has mainly relied on health measures such as EQ-5D across populations and conditions. We want to know how well the EQ-5D performs in the target population to avoid bias to the disadvantage of older adults and care-dependents. Therefore, we aim to explore differences and similarities of EQ-5D-3L and EQ-5D-5L in comparison to the old-age specific WHOQOL-OLD instrument in a sample of older adults receiving aged care services. We collected data from n = 329 older adults (≥65 years) receiving aged care services in Germany; the majority was at least 80 years and had varying care needs. We assessed instruments' feasibility, test-retest reliability, instruments' association and sensitivity to known-group differences. In terms of feasibility and test-retest reliability both EQ-5D versions performed better than the WHOQOL-OLD. All measures differentiated well between groups based on aspects of general health and care levels. The analysis of relationship between measures indicated that EQ-5D and WHOQOL-OLD assess partially overlapping, but distinct constructs. We found no clear evidence of superiority of either EQ-5D version over the other. The EQ-5D-5L performed better in terms of test-retest reliability and stronger correlations with WHOQOL-OLD facets. We conclude that using the WHOQOL-OLD alongside EQ-5D in this sample added further information on different aspects of quality of life.

Abstract
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.

[DOI: 10.1186/s12955-022-02062-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 10/24/2022] [Indexed: 11/20/2022] Open
Abstract
Abstract
Objectives
To explore through a systematic review, the convergent validity of EQ-5D (EQ-5D-3L and EQ-5D-5L (total score and dimensions)) with core outcomes in dementia and investigate how this may be impacted by rater-type; with the aim of informing researchers when choosing measures to use in dementia trials.
Methods
To identify articles relevant to the convergent validity of EQ-5D with core dementia outcomes, three databases were electronically searched to September 2022. Studies were considered eligible for inclusion within the review if they included individual level data from people with dementia of any type, collected self and/or proxy reported EQ-5D and collected at least one core dementia outcome measure. Relevant data such as study sample size, stage of dementia and administration of EQ-5D was extracted, and a narrative synthesis was adopted.
Results
The search strategy retrieved 271 unique records, of which 30 met the inclusion criteria for the review. Twelve different core outcome measures were used to capture dementia outcomes: cognition, function, and behaviour/mood across the studies. Most studies used EQ-5D-3L (n = 27). Evidence related to the relationship between EQ-5D and measures of function and behaviour/mood was the most robust, with unanimous directions of associations, and more statistically significant findings. EQ-5D dimensions exhibited associations with corresponding clinical outcomes, whereby relationships were stronger with proxy-EQ-5D (than self-report).
Conclusion
Measuring health-rated quality of life in dementia populations is a complex issue, particularly when considering balancing the challenges associated with both self and proxy report. Published evidence indicates that EQ-5D shows evidence of convergent validity with the key dementia outcomes, therefore capturing these relevant dementia outcomes. The degree of associations with clinical measures was stronger when considering proxy-reported EQ-5D and differed by EQ-5D dimension type. This review has revealed that, despite the limited targeted psychometric evidence pool and reliance on clinical and observational studies, EQ-5D exhibits convergent validity with other dementia outcome measures.

Abstract
PURPOSE To determine feasibility and validity of the EQ-5D-3L in the elderly European population. METHODS Secondary data analysis based on the study of health, ageing, and retirement in Europe (SHARE) to determine the percentage of missing items for EQ-5D dimensions and EQ VAS, and to demonstrate convergent/divergent validity with measures included in the SHARE survey. Known-groups validity was tested using literature-based hypotheses. Correlation coefficients and Cohen's f are reported. RESULTS Missing values were below 3% across all EQ-5D dimensions and gender strata, slightly increasing with age. Individuals' responses to each EQ-5D dimension were related to their ratings of other measures in expected directions. The EQ VAS and all EQ-5D dimensions (except anxiety/depression) moderately to strongly correlated with physical [e.g. number of limitations in activities of daily living (ADL): r = 0.313-0.658] and generic measures [CASP (control, autonomy, self-realization, pleasure)-19 scale, self-perceived health, number of symptoms: r = 0.318-0.622], while anxiety/depression strongly correlated with the EURO-D scale (r = 0.527). Both EQ-5D dimensions and EQ VAS discriminated well between two [or more] groups known to differ [e.g. anxiety/depression discriminated well between persons classified as depressed/not depressed using the EURO-D scale, f = 0.51; self-care differentiated best between individuals without and with 1 + ADL limitations, f = 0.69]. Sociodemographic variables like gender, education, and partner in household were hardly associated with EQ VAS scores (f < 0.25). CONCLUSION With item non-response of less than 3%, good discriminatory, and construct properties, the EQ-5D-3L showed to be a feasible and valid measure in the elderly Europeans.

[PMID: 35636050 DOI: 10.1016/j.socscimed.2022.115046] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 04/04/2022] [Accepted: 05/14/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE Quality of life is an important person-centred outcome in health and aged care settings. Due to an increasing prevalence of cognitive decline and dementia in ageing populations, a proportion of older people receiving health and aged care services may not be able to reliably assess their own quality of life, highlighting the need for proxy assessment. This systematic review sought to investigate the level of agreement between self and proxy-report of older people's quality of life using established preference-based instruments of quality of life suitable for economic evaluation. METHODS A systematic review was conducted following PRISMA guidelines. Eight databases were searched: Web of Science, Scopus, Medline, Econlit, PsychINFO, CINAHL, Ageline and Cochrane Library. Information was extracted on the instruments, population samples (including any cognitive thresholds applied), mean scores, type of proxy, and measures of inter-rater agreement. RESULTS A total of 50 studies using eight different preference-based quality of life instruments were identified. Most studies were cross-sectional (72%) with a wide variety of cognitive assessments and thresholds applied to define older participants with cognitive impairment. The most common proxies were family members, mostly spouses. The level of agreement between self and proxy-report was generally poor - irrespective of the instrument applied or type of proxy - with proxy-report generally indicating lower levels of quality of life than self-report. There was some evidence of stronger agreement on more observable quality of life domains e.g., physical health and mobility, relative to less observable domains e.g. emotional well-being. Few studies tracked self and/or proxy-report of quality of life longitudinally. CONCLUSIONS More research is needed to develop evidence to inform guidance on self-report versus proxy-report of quality of life for older people receiving health and aged care services. Until then, the collection of both self and proxy reports as complementary measures is indicated.

Abstract
OBJECTIVES Understanding disability-adjusted life-years (DALYs) based on dementia subtypes and mild cognitive impairment (MCI) is essential for optimal resource allocation. This study aimed to investigate disease burdens of various dementias and MCI in a representative South Korean population. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS 6481 Korean older adults. METHODS We estimated the disease-specific DALYs. RESULTS DALYs due to MCI and all-cause dementia are estimated to increase from 1295 per 100,000 in 2016 to 9501 per 100,000 in 2065. In 2016, DALYs attributed to Alzheimer's dementia, vascular dementia, and MCI accounted for 33% (423 per 100,000), 20% (316 per 100,000), and 24% (123 per 100,000), respectively, of the total DALYs due to MCI and all-cause dementia. In 2065, DALYs due to Alzheimer's dementia, vascular dementia, and MCI will account for 38% (3654 per 100,000), 17% (1654 per 100,000), and 27% (2585 per 100,000) of total DALYs due to MCI and all-cause dementia, respectively. The years of life lived with disability (YLDs) due to MCI and all-cause dementia are estimated to rise from 479 per 100,000 in 2016 to 2807 per 100,000 in 2065. In 2016, YLDs due to Alzheimer's dementia, vascular dementia, and MCI composed 37% (177 per 100,000), 18% (85 per 100,000), and 15% (70 per 100,000), respectively, of the total YLDs due to MCI and all-cause dementia. In 2065, YLDs due to Alzheimer's dementia, vascular dementia, and MCI will account for 48% (1358 per 100,000), 15% (410 per 100,000), and 10% (290 per 100,000), respectively, of total YLDs due to MCI and all-cause dementia. CONCLUSIONS AND IMPLICATIONS Considering the rapidly growing disease burden, resources should be allocated to continuously monitor and manage the MCI and dementia burden. Particular attention to Alzheimer's dementia is required considering its significant contribution to current and future disease burden, especially to YLD.

Changes in Health-Related Quality of Life for Older Persons With Cognitive Impairment After Hip Fracture Surgery: A Systematic Review. J Nurs Res 2021; 28:e97.

Abstract
BACKGROUND Hip fractures in persons with cognitive impairments represent a major public health issue in older populations that often results in poor health-related quality of life (HRQoL). PURPOSE The aim of this systemic review was to examine the changes in HRQoL in older, cognitively impaired patients with hip fracture who had received surgical treatment. METHODS A literature search of PubMed, Scopus, MEDLINE, PsycINFO, and CINAHL (EBSCO) databases was conducted for studies published up to July 2018 that addressed the issue of HRQoL in cognitively impaired patients with hip fracture after surgery. Studies that met the following criteria were included: Patients with hip fracture were over 60 years old and had cognitive impairment or dementia, patients had undergone hip fracture repair surgery, HRQoL was determined using standardized questionnaires, a descriptive or interventional methodology was used, and the full-text article was available in English. RESULTS A primary search of databases yielded 1,528 studies, 621 duplicates were removed, and the remaining 907 abstracts were screened. Thirty-four full-text articles were deemed relevant for full review; of these, 10 articles met the criteria for inclusion in the review. Cognitive impairment was found to impact negatively on the patients' HRQoL after hip fracture surgery (n = 809). Severity of cognitive impairment was correlated with deterioration in HRQoL after hospital discharge. When compared with prefracture measures of HRQoL, the greatest deterioration in HRQoL postsurgery occurred during the first 4 months after discharge. Impacts on HRQoL for patients with cognitive impairment at later time points differed depending on type of hip fracture and type of surgical treatment. However, for most of the patients, HRQoL remained relatively unchanged at 6, 12, and 24 months postdischarge. CONCLUSIONS We recommend nursing care interventions for older persons with cognitive impairment be initiated immediately after surgery for hip fracture to prevent a significant decline in HRQoL. Further examination of interventions that are effective in maintaining HRQoL for these patients such as interdisciplinary care is necessary. In addition, the influences of hip fracture type and surgical approach on changes in HRQoL suggest a need for further investigations to determine what contributed to the observed inconsistencies in the outcomes.

Abstract
OBJECTIVE Our study examined the feasibility and validity of the EQ-5D-5L proxy questionnaire in measuring health-related quality of life (HRQoL) of nursing home residents. METHODS Twenty-four nurses and 229 residents from 3 nursing homes in Singapore participated in this cross-sectional study. Nurses assessed residents under their care with the EQ-5D-5L proxy questionnaire. Two experienced mappers conducted Dementia Care Mapping (DCM) within 1 month in a subsample of the residents. Feasibility was evaluated according to percentage of unanswered EQ-5D-5L items and proportion of nurses who failed to respond to all items. Convergent validity was assessed by examining the correlation between EQ-5D-5L measures and DCM scores. Known-groups validity was assessed by comparing differences in EQ-5D-5L scores for residents with varying communication abilities and physical functions. RESULTS The nurses' mean age was 35.4 years while the residents' was 73.4 years. Most residents were female (51.3%) and had the ability to communicate (81.3%). For 6 of the 229 residents (2.6%), not all items in the EQ-5D-5L were completed. The EQ-5D-5L index score correlated positively and moderately with the DCM's well/ill-being score (r = 0.433, n = 90, P < 0.01). Residents who were able to communicate effectively or had better physical function were assessed to have less severe health problems and better EQ-5D-5L scores. CONCLUSION The EQ-5D-5L proxy questionnaire has adequate feasibility and validity when used by nurses to assess the HRQoL of nursing home residents. As it is brief and can be conveniently administered, it can be deployed on a larger scale to assess HRQoL of nursing home residents.

Abstract
BACKGROUND Assessing quality of life (QoL) in older people with cognitive impairment is a challenge. There is no consensus on the best tool, but a short, user-friendly scale is advised. OBJECTIVE This study aimed to assess the psychometric properties of the self-reported and generic EQ-5D (including the EQ index and EQ visual analog scale [VAS]) in community-dwelling older adults with cognitive impairment. METHODS Cross-sectional study analyzing the feasibility, acceptability, reliability, and validity of the EQ-5D based on 188 self-administered questionnaires in a sample of community-dwelling older adults with Mini-Mental State Examination (MMSE) scores of 10 to 24 points. RESULTS The EQ index was 0.69 (±0.27) and the EQ VAS was 63.8 (±28.54). Adequate measurement properties were found in acceptability and feasibility. Cronbach's alpha was 0.69. Good validity was observed in the correlation of each dimension of the EQ-5D with geriatric assessment scales. Higher validity was observed for the EQ index compared to the EQ VAS. CONCLUSION The EQ-5D scale could be a good tool for assessing health-related QoL in community-dwelling older adults with cognitive impairment, though it is necessary to assess the dimensions and the EQ index.

Abstract
BACKGROUND Quality of life (QoL) is recognized as an important patient-reported outcome measure. Assessing QoL in older people with cognitive impairment is a challenge due to discrepancies in the collection of data via proxies versus self-report. This study aimed to assess the psychometric properties of the self-reported EQ-5D (including the EQ index and EQ visual analog scale (VAS)) in nursing homes residents with cognitive impairment and to analyze its validity based on scales included in the comprehensive geriatric assessment. METHODS Cross-sectional, multicenter study analyzing the feasibility, acceptability, reliability, and validity of the EQ-5D based on 251 self-administered questionnaires in a sample of nursing home residents with cognitive impairment. Reference scales were those from the comprehensive geriatric assessment, equivalent to the five dimensions of the EuroQol. RESULTS The EQ index was 0.31 (0.37) and the EQ VAS was 35.96 (29.86), showing adequate acceptability and feasibility. Cronbach's alpha was 0.723. The EQ index and EQ VAS, as outcome variables for multiple linear regression models including CGA titration scales, showed better validity for the EQ index than the EQ VAS. CONCLUSIONS As a self-administered generic scale, the EQ-5D-3L could be a good tool for QoL assessment in nursing home residents with cognitive impairment.

Abstract
Abstract
Background
For health professionals working with older adults with physical and cognitive impairments, improving or maintaining clients’ quality of life and well-being is of crucial importance. The aim of this study was to evaluate validity and utility of assessments of quality of life and well-being in German suitable for this group of clients.
Methods
In an initial literature search, we identified potentially viable assessments based on existing systematic reviews. We then conducted a systematic literature search in the databases Medline, CINAHL, and PsycINFO using keywords related to validity, utility, client group, and German. Assessments for which sufficient evidence was found were evaluated regarding their validity and utility when used with older adults with physical and cognitive impairments.
Results
For 14 of 27 initially identified assessments, sufficient evidence was found to evaluate validity and utility with this client group. WHOQOL-BREF, WHOQOL-OLD, WHO-5, EUROHIS-QOL 8, SF-36, SF-12, EQ-5D, NHP, SEIQOL-DW, SWLS, PANAS, DQOL, QOL-AD, and QUALIDEM were evaluated based on 82 studies. Of these, WHOQOL-BREF, WHO-5, SF-36, SF-12, EQ-5D, NHP, QUALIDEM, QOL-AD and DQOL are presented here.
Conclusion
Assessments differed widely in the way they operationalized quality of life/well-being, use of self-evaluation or evaluation-by-proxy, and amount of available evidence for their validity and utility. On the basis of our results in regard to the assessments’ validity, utility, and appropriateness of operationalization of quality of life/well-being to the client group, three assessments were recommended for use: WHOQOL-BREF for self-evaluation, QUALIDEM for evaluation-by-proxy in case of severe dementia, and EQ-5D for cost-utility analyses.

Quality of life in nursing home residents with pain: pain interference, depression and multiple pain-related diseases as important determinants. Qual Life Res 2019; 29:91-97. [PMID: 31542867 PMCID: PMC6962122 DOI: 10.1007/s11136-019-02290-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/28/2019] [Indexed: 11/27/2022]
Abstract
AIM Quality of life is an essential outcome parameter in geriatric research and presents an important indicator for the evaluation of care treatments. The present study analyses potential impact factors on health-related quality of life (HRQOL) of nursing home residents (NHR) who are in pain. METHODS Data came from the cRCT 'PIASMA'. Statistical analyses of 146 respondents were carried out by multiple linear regressions based on the EQ-5D index (Euroquol Quality of Life) as dependent variable. Potential impact factors were applied and categorised in five blocks: pain intensity and interference (according to the Brief Pain Inventory), intervention effect, sex and age, pain-related diagnoses, and scales regarding depressive symptoms and cognitive impairment (based on the Geriatric Depression Scale and the Mini-Mental State Examination). RESULTS On average, residents showed a pain intensity of 18.49, a pain interference of 29.61, a MMSE score of 22.84, a GDS score of 5.65 and an EQ-5D index of 0.52. Residents with more diagnoses, more depressive symptoms, and a higher pain interference showed a significantly reduced HRQOL. CONCLUSION Findings underline the importance of identifying and applying treatment options for both pain (especially interference) and depressive disorders to maintain HRQOL of NHR.

Watts RD, Li IW. Use of Checklists in Reviews of Health Economic Evaluations, 2010 to 2018. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2019; 21:471-481. [PMID: 30832977 DOI: 10.1016/j.jval.2017.09.005] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2017] [Revised: 08/31/2017] [Accepted: 09/09/2017] [Indexed: 05/17/2023]
Abstract
OBJECTIVE It is useful for reviewers of economic evaluations to assess quality in a manner that is consistent and comprehensive. Checklists can allow this, but there are concerns about their reliability and how they are used in practice. We aimed to describe how checklists have been used in systematic reviews of health economic evaluations. METHODS Meta-review with snowball sampling. We compiled a list of checklists for health economic evaluations and searched for the checklists' use in systematic reviews from January 2010 to February 2018. We extracted data regarding checklists used, stated checklist function, subject area, number of reviewers, and issues expressed about checklists. RESULTS We found 346 systematic reviews since 2010 that used checklists to assess economic evaluations. The most common checklist in use was developed in 1996 by Drummond and Jefferson, and the most common stated use of a checklist was quality assessment. Checklists and their use varied within subject areas; 223 reviews had more than one reviewer who used the checklist. CONCLUSIONS Use of checklists is inconsistent. Eighteen individual checklists have been used since 2010, many of which have been used in ways different from those originally intended, often without justification. Different systematic reviews in the same subject areas would benefit from using one checklist exclusively, using checklists as intended, and having 2 reviewers complete the checklist. This would increase the likelihood that results are transparent and comparable over time.

Reducing Implant Infection in Orthopaedics (RIIiO): a pilot study for a randomised controlled trial comparing the influence of forced air versus resistive fabric warming technologies on postoperative infection rates following orthopaedic implant surgery in adults. Trials 2018; 19:640. [PMID: 30454034 PMCID: PMC6245696 DOI: 10.1186/s13063-018-3011-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 10/21/2018] [Indexed: 11/30/2022] Open
Abstract
Background Approximately 70,000 to 75,000 proximal femoral fracture repairs take place in the UK each year. Hemiarthroplasty is the preferred treatment for adults aged over 60 years. Postoperative infection affects up to 3% of patients and is the single most common reason for early return to theatre. Ultraclean ventilation was introduced to help mitigate the risk of infection, but it may also contribute to inadvertent perioperative hypothermia, which itself is a risk for postoperative infection. To counter this, active intraoperative warming is used for all procedures that take 30 min or more. Forced air warming (FAW) and resistive fabric warming (RFW) are the two principal techniques used for this purpose; they are equally effective in prevention of inadvertent perioperative hypothermia, but it is not known which is associated with the lowest infection rates. Deep surgical site infection doubles operative costs, triples investigation costs and quadruples ward costs. The Reducing Implant Infection in Orthopaedics (RIIiO) study seeks to compare infection rates with FAW versus RFW after hemiarthroplasty for hip fracture. A cost-neutral intervention capable of reducing postoperative infection rates would likely lead to a change in practice, yield significant savings for the health economy, reduce overall exposure to antibiotics and improve outcomes following hip fracture in the elderly. The findings may be transferable to other orthopaedic implant procedures and to non-orthopaedic surgical specialties. Methods RIIiO is a parallel group, open label study randomising hip fracture patients over 60 years of age who are undergoing hemiarthroplasty to RFW or FAW. Participants are followed up for 3 months. Definitive deep surgical site infection within 90 days of surgery, the primary endpoint, is determined by a blinded endpoint committee. Discussion Hemiarthroplasty carries a risk of deep surgical site infection of approximately 3%. In order to provide 90% power to demonstrate an absolute risk reduction of 1%, using a 5% significance level, a full trial would need to recruit approximately 8630 participants. A pilot study is being conducted in the first instance to demonstrate that recruitment and data management strategies are appropriate and robust before embarking on a large multi-centre trial.

Abstract
INTRODUCTION Quality of life of people with advanced dementia living in nursing homes is often suboptimal. Family caregivers can feel frustrated with limited contact with their relatives, which results in visits that are perceived as stressful and not very meaningful. Few psychosocial interventions are specifically developed for people with advanced dementia, and actively involve family caregivers or volunteers. Also, interventions usually stop when it becomes difficult for people to participate. The Namaste Care Family programme aims to increase the quality of life of people with advanced dementia, and improve family caregiving experiences through connecting to people and making them comfortable. METHODS AND ANALYSIS Our study will evaluate the effects of the Namaste Care Family programme on quality of life of people with advanced dementia living in nursing homes and family caregiving experiences using a cluster-randomised controlled trial. Longitudinal analyses will be performed taking into account clustering at the nursing home level. Both a cost-effectiveness and a cost-utility analysis from a societal perspective will be performed. We will modify the Namaste Care Family programme to increase family and volunteer involvement in ongoing and end-of-life care. Data collection involves assessments by family caregivers, nursing staff and elderly care physicians using questionnaires, and observations by the researchers at baseline and multiple times over 12 months. The last questionnaire will be sent up to month 24 after the death of the person with dementia. During semistructured interviews, the feasibility, accessibility and sustainability of the Namaste Care Family programme will be assessed. ETHICS AND DISSEMINATION The study protocol is approved by the Medical Ethics Review Committee of the VU University Medical Center in Amsterdam (protocol no. 2016.399) and registered with the Nederlands Trial Register (NTR5692). The findings will be disseminated via publications in peer-reviewed journals, conference presentations and presentations for healthcare professionals where appropriate. TRIAL REGISTRATION NUMBER NTR5692.

Abstract
Given the expected increase in the number of people with dementia in the coming years, it is anticipated that the resources necessary to support those with dementia will significantly increase. There will therefore likely be increased emphasis on how best to use limited resources across a number of domains including prevention, diagnosis, treatment and supporting informal caregivers. There has been increasing use of economic methods in dementia in the past number of years, in particular, cost-of-illness analysis and economic evaluation. This paper reviews the aforementioned methods and identities a number of methodological issues that require development. Addressing these methodological issues will enhance the quality of economic analysis in dementia and provide some useful insights about the best use of limited resources for dementia.

Abstract
INTRODUCTION An investigation into long-term cognitive impairment and Quality of Life (QoL) after severe burns. METHODS A proof of principle, cohort design, prospective, observational clinical study. Patients with severe burns (>15% TBSA) admitted to Burns ICU for invasive ventilation were recruited for psychocognitive assessment with a convenience sample of age and sex-matched controls. Participants completed psychological and QoL questionnaires, the Cogstate® electronic battery, Hopkins Verbal Learning, Verbal Fluency and Trail making tasks. RESULTS 15 patients (11M, 4F; 41±14 years; TBSA 38.4%±18.5) and comparators (11M, 4F; 40±13 years) were recruited. Burns patients reported worse QoL (Neuro-QoL Short Form v2, patient 30.1±8.2, control 38.7±3.2, p=0.0004) and cognitive function (patient composite z-score 0.01, IQR -0.11 to 0.33, control 0.13, IQR 0.47-0.73, p=0.02). Compared to estimated premorbid FSIQ, patients dropped an equivalent of 8 IQ points (p=0.002). Cognitive function negatively correlated with burn severity (rBaux score, p=0.04). QoL strongly correlated with depressive symptoms (Rho=-0.67, p=0.009) but not cognitive function. CONCLUSIONS Severe burns injuries are associated with a significant, global, cognitive deficit. Patients also report worse QoL, depression and post-traumatic stress. Perceived QoL from cognitive impairment was more closely associated with depression than cognitive impairment.

Abstract
BACKGROUND There is currently no disease-modifying treatment available to halt or delay the progression of the disease pathology in dementia. An agreed core set of the best-available and most appropriate outcomes for disease modification would facilitate the design of trials and ensure consistency across disease modification trials, as well as making results comparable and meta-analysable in future trials. OBJECTIVES To agree a set of core outcomes for disease modification trials for mild to moderate dementia with the UK dementia research community and patient and public involvement (PPI). DATA SOURCES We included disease modification trials with quantitative outcomes of efficacy from (1) references from related systematic reviews in workstream 1; (2) searches of the Cochrane Dementia and Cognitive Improvement Group study register, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Latin American and Caribbean Health Sciences Literature and PsycINFO on 11 December 2015, and clinical trial registries [International Standard Randomised Controlled Trial Number (ISRCTN) and clinicaltrials.gov] on 22 and 29 January 2016; and (3) hand-searches of reference lists of relevant systematic reviews from database searches. REVIEW METHODS The project consisted of four workstreams. (1) We obtained related core outcome sets and work from co-applicants. (2) We systematically reviewed published and ongoing disease modification trials to identify the outcomes used in different domains. We extracted outcomes used in each trial, recording how many used each outcome and with how many participants. We divided outcomes into the domains measured and searched for validation data. (3) We consulted with PPI participants about recommended outcomes. (4) We presented all the synthesised information at a conference attended by the wider body of National Institute for Health Research (NIHR) dementia researchers to reach consensus on a core set of outcomes. RESULTS We included 149 papers from the 22,918 papers screened, referring to 125 individual trials. Eighty-one outcomes were used across trials, including 72 scales [31 cognitive, 12 activities of daily living (ADLs), 10 global, 16 neuropsychiatric and three quality of life] and nine biological techniques. We consulted with 18 people for PPI. The conference decided that only cognition and biological markers are core measures of disease modification. Cognition should be measured by the Mini Mental State Examination (MMSE) or the Alzheimer's Disease Assessment Scale - Cognitive subscale (ADAS-Cog), and brain changes through structural magnetic resonance imaging (MRI) in a subset of participants. All other domains are important but not core. We recommend using the Neuropsychiatric Inventory for neuropsychiatric symptoms: the Disability Assessment for Dementia for ADLs, the Dementia Quality of Life Measure for quality of life and the Clinical Dementia Rating scale to measure dementia globally. LIMITATIONS Most of the trials included participants with Alzheimer's disease, so recommendations may not apply to other types of dementia. We did not conduct economic analyses. The PPI consultation was limited to members of the Alzheimer's Society Research Network. CONCLUSIONS Cognitive outcomes and biological markers form the core outcome set for future disease modification trials, measured by the MMSE or ADAS-Cog, and structural MRI in a subset of participants. FUTURE WORK We envisage that the core set may be superseded in the future, particularly for other types of dementia. There is a need to develop an algorithm to compare scores on the MMSE and ADAS-Cog.

Abstract
The purpose of this study is to evaluate the health-related quality of life (HrQoL) of patients with Alzheimer's disease (AD) in different care settings (institutionalized versus community-dwelling) across all severity stages of dementia. Patients were consecutively recruited with their primary caregivers (123 inpatients and 272 outpatients), and the impact of patient-related parameters such as behavioral and psychological symptoms of dementia (BPSD) (Geriatric Depression Scale [GDS] and Neuropsychiatric Inventory [NPI]) and functional capacity (Alzheimer's Disease Cooperative Study-Activities of Daily Living [ADCS-ADL]) on HrQoL was analyzed. Patients' HrQoL was assessed using self-reported and caregiver-rated generic (EuroQoL Instrument) and dementia-specific (Quality of Life-Alzheimer's Disease [Qol-AD]) scales. Patients reported a considerably higher HrQoL than their caregivers on the QoL-AD, EQ-5D, and EQ VAS (p < 0.001). Different dementia severity groups showed significantly worse results in HrQoL for patients with lower MMSE scores. The mean self-reported QoL-AD decreased from 32.3±5.7 in the group with the highest MMSE scores to 27.1±5.5 in patients with the lowest MMSE scores (p < 0.001). A considerably lower HrQoL was shown for institutionalized patients versus participants in outpatient settings (proxy-rated QoL-AD 19.7±4.6 versus 26.0±7.1, p < 0.001). Depressive symptoms (GDS), BPSD (NPI), and reduced functional capacity (ADCS-ADL) were evaluated for their impact on patients' HrQoL. Multivariate models explained between 22% and 54% of the variance in patients' HrQoL. To analyze the causative direction of the reported associations, further longitudinal studies should be conducted.

Abstract
BACKGROUND Families and nurses are important care-providers and proxies of older people. Their ability to assess the quality of life of elders in ways that align with how older people assess themselves has policy implications for allocating services and resources to older persons. AIM To investigate the alignment of perspectives of the quality of life held by older people, their families and nurses in China. METHODS Employing a survey design using concurrent EQ-5D-3L and WHOQOL-BREF surveys, responses from 72 matched stakeholder groups were compared and agreement tested using weighted kappa/one-way random intra-class correlations and paired Student's t-test. RESULTS On the more observable dimensions families and nurses were in close agreement with the older person in relation to quality of life reports. However, in the more subjective domains, family and especially nurses tended to estimate that the older person's suffering as more severe than they themselves thought. CONCLUSION The perspectives of older patients and their family are more closely aligned regarding the older person's quality of life than that of nurses caring for them, a finding inconsistent with international research. IMPLICATION FOR NURSING AND HEALTH POLICY The evidence suggests that nursing work assignment processes could influence the accuracy of nurses' perceptions of their patient's quality of life.

Abstract
OBJECTIVES To assess the independent association between health-related quality of life (HRQOL) at admission and mortality, functional decline, and institutionalization 3 and 12 months after admission in acutely hospitalized older adults. DESIGN Post hoc analysis of data from prospective cohort study, 2006 to 2009, 12-month follow-up. SETTING Eleven medical wards in three hospitals in the Netherlands. PARTICIPANTS Medical patients aged 65 and older acutely hospitalized for 48 hours or longer (N = 473). MEASUREMENTS OUTCOMES mortality, functional decline, and institutionalization, 3 and 12 months after admission. Main determinant was HRQOL (utility based on the EuroQol-5D at admission, reflecting the relative desirability of a particular health state and is measured on a scale from 0 (death) to 1 (full health). Some health states are regarded as being worse than death, resulting in negative utilities, with a minimum of -0.330). Participants were split into two groups based on median utility at admission. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using Cox and logistic regression analyses, adjusted for sociodemographic and health variables. RESULTS Median utility was 0.775 (interquartile range 0.399-0.861). Utility greater than 0.775, indicating high HRQOL, was associated with lower risk of mortality (hazard ratio = 0.38, 95% CI = 0.18-0.83) and functional decline (OR = 0.47, 95% CI = 0.28-0.79) at 3 months in the adjusted models. At 12 months, these associations were statistically significant in the crude models but not in the adjusted models. Utility was not associated with risk of institutionalization at 3 or 12 months. CONCLUSION Higher HRQOL at admission was associated with lower risk of mortality and functional decline 3 months after admission. In older, acutely hospitalized individuals, the EQ-5D may provide a means of risk stratification and may ultimately guide individuals, their families, and professionals in treatment decisions during hospitalization.

Abstract
OBJECTIVES The objective of this study was to analyse how hospitalisation after the age of 60 affected individuals' health-related quality of life (HRQoL). The main hypothesis was that a hospital admission in old age can be seen as a proxy of ill health and possibly as a health divider, separating life into a healthy and an unhealthy part. The extent to which this is true depends on which disease individuals face and how functional ability and HRQoL are affected. SETTINGS This was a longitudinal study, based on an older cohort of individuals who participated in the Stockholm Public Health Cohort (SPHC) survey in 2006; the survey took place in Stockholm, Sweden. Information regarding hospitalisations and deaths, which is available through Swedish administrative registers, was linked to the survey from the National Patient Register and Cause of Death Register. PARTICIPANTS 2101 individuals, 65+ years old at inclusion, with no previous hospitalisations at baseline (2006), were followed for 4 years until 2010 (end of follow-up). PRIMARY AND SECONDARY OUTCOME MEASURES HRQoL was assessed through a utility index derived from the EuroQol 5D questionnaire, at baseline and at 2010. The change in HRQoL after admission(s) to the hospital was estimated as the difference between the 2010 and 2006 levels using linear regression, also considering several covariates. RESULTS A single hospitalisation did not reduce individuals' HRQoL, either for men or women. On the other hand, multiple any-cause hospitalisations reduced HRQoL between 3.2% and 6.5%. When looking into hospitalisations for specific causes, such as hip fractures, a decrease in HRQoL was observed as well; however, conclusions regarding this were impeded by the small sample size. CONCLUSIONS Hospital admissions in old age may indicate a shift from a healthy life to a life of compromised health when considering their frequency and cause over a period of time.

Abstract
BACKGROUND Research on new treatments for dementia is gaining pace worldwide in an effort to alleviate this growing health care problem. The optimal evaluation of such interventions, however, calls for a practical and credible patient-reported outcome measure. OBJECTIVES To describe the refinement of the Dementia Quality-of-life Instrument (DQI) and present its revised version. METHODS A prototype of the DQI was adapted to cover a broader range of health-related quality of life (HRQOL) and to improve consistency in the descriptions of its domains. A valuation study was then conducted to assign meaningful numbers to all DQI health states. Pairs of DQI states were presented to a sample of professionals working with people with dementia and a representative sample of the Dutch population. They had to repeatedly select the best DQI state, and their responses were statistically modeled to obtain values for each health state. RESULTS In total, 207 professionals working with people with dementia and 631 members of the general population completed the paired comparison tasks. Statistically significant differences between the two samples were found for the domains of social functioning, mood, and memory. Severe problems with physical health and severe memory problems were deemed most important by the general population. In contrast, severe mood problems were considered most important by professionals working with people with dementia. DISCUSSION The DQI is a simple and feasible measurement instrument that expresses the overall HRQOL of people suffering from dementia in a single meaningful number. Current results suggest that revisiting the discussion of using values from the general population might be warranted in the dementia context.

Abstract
PURPOSE This study aimed to assess and compare the psychometric performance of the EQ-5D in relation to other dementia-specific measures, the QoL-AD and DEMQoL, within a psychosocial intervention study. METHODS Two hundred and seventy-two people with dementia completed the EQ-5D, DEMQoL and QoL-AD. Convergent and discriminant validity of the measures were assessed, and inter-rater reliability was tested by comparing the self-reported and proxy scores of the measures. Internal consistency was tested using Cronbach's alpha. RESULTS Results satisfy convergent validity amongst the three outcome measures. EQ-5D, DEMQoL and QoL-AD total scores were shown to be significantly correlated with each other (p < 0.001) in both participants with dementia and proxy reports. Results also satisfied discriminant validity for participant EQ-5D, DEMQoL and QoL-AD total scores. In relation to reliability between self and proxy scores, the EQ-5D showed higher reliability scores between participant and proxy total scores for mild and moderate level of cognitive impairment and performed better than the dementia-specific measures. Reliability assessed through Cronbach's alpha was satisfactory, indicating adequate internal consistency of all three measures. CONCLUSIONS The results suggest that the EQ-5D might have advantages over other dementia-specific measures, and it could be used routinely and as a stand-alone measure of quality of life in dementia research.

Abstract
BACKGROUND Current treatments for Alzheimer's disease (AD) provide modest symptomatic relief but do not slow the progression of the disease. Latrepirdine may modulate several targets involved in AD pathology, including lipid peroxidation, mitochondrial permeability, voltage-gated calcium ion channels as well as neurotransmitter receptor activity, and thus potentially represents both a symptomatic and disease-modifying intervention. Several randomized, placebo-controlled trials have sought to evaluate the effect of latrepirdine on cognition, function and behaviour in patients with AD. OBJECTIVES To evaluate the efficacy and safety of latrepirdine for the treatment of AD. SEARCH METHODS We searched the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group on 4 June 2014 using the terms: latrepirdine OR dimebon OR dimebolin OR 2,3,4,5-tetrahydro-2,8-dimethyl-5- (2-(6-methyl-3-pyridyl)ethyl)-1H-pyrido(4,3-b)indole. SELECTION CRITERIA We included all randomized, double-blind, placebo-controlled trials where latrepirdine was administered to patients with mild, moderate or severe AD. DATA COLLECTION AND ANALYSIS We assessed the quality of studies and two authors extracted data. We calculated mean difference (MD), risk ratio (RR) and 95% confidence interval (CI) on an intention-to-treat (ITT) basis for all relevant outcome measures. MAIN RESULTS Seven trials involving a total of 1697 participants were found and six were included in the quantitative analyses. No data were available from the seventh trial. Three trials involving 1243 patients were included in analyses of efficacy outcomes, and four trials involving 1034 patients were included in analyses of safety and tolerability outcomes. We judged five trials to be at high risk of bias due to selective outcome reporting and three to be at high risk of attrition bias. There was low quality evidence favouring latrepirdine on the Clinician's Interview - Based Impression of Change Plus Caregiver Input after 26 weeks (CIBIC-Plus) (MD -0.60, 95% CI -0.89 to -0.31, 1 study, P < 0.001). Due to imprecision in the results, it was not possible to determine whether latrepirdine had any effect on cognition measured with the Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-Cog) (MD -1.49, 95% CI -3.47 to 0.49, 3 studies, P = 0.14) or the Mini-Mental State Examination (MMSE) (MD 0.59, 95% CI -0.94 to 2.11, 3 studies, P = 0.45), or on function measured with the Alzheimer's Disease Co-operative Study - Activities of Daily Living scale (ADCS-ADL) (MD 1.00, 95% CI -1.15 to 3.15, 3 studies, P = 0.36) at study endpoint (26 or 52 weeks). We considered the evidence provided on these outcomes to be of overall low quality. However, there was some high quality evidence showing a very small benefit of latrepirdine on the Neuropsychiatric Inventory (NPI) (MD -1.77, 95% CI -3.09 to -0.45, 3 studies, P = 0.009) at study endpoint (26 or 52 weeks). Additionally, moderate quality evidence suggested that latrepirdine and placebo were comparable in adverse events (RR 1.03, 95% CI 0.93 to 1.14, P = 0.51), serious adverse events (RR 0.86, 95% CI 0.55 to 1.35, P = 0.52), dropouts (RR 0.91, 95% CI 0.65 to 1.27, P = 0.57) and dropouts due to adverse events (RR 0.98, 95% CI 0.57 to 1.67, P = 0.93). AUTHORS' CONCLUSIONS Our meta-analysis is limited by the small number of studies, imprecision, inconsistencies between studies and likelihood of bias. Nevertheless, the evidence to date suggests that while not associated with an increased risk of adverse events compared with placebo, there is no effect of latrepirdine on cognition and function in mild-to-moderate AD patients, though there appears to be a modest benefit for behaviour. Further studies should investigate the potential benefit of latrepirdine on neuropsychiatric symptoms in AD.

Abstract
BACKGROUND Older people with complex needs live mainly at home. Several types of gerontological coordinations have been established on the French territory to meet their needs and to implement social and primary health care services. But we do not have any information on the use of these services at home as a function of the coordination method used. METHODS We compared the use of home care services for older people with complex needs in three types of coordination with 12 months' follow-up. The three coordinations regrouped a gerontological network with case management (n=105 persons), a nursing home service (SSIAD) with a nurse coordination (n=206 persons) and an informal coordination with a non-professional caregiver (n=117 persons). RESULTS At t0, the older people addressed to the gerontological network had less access to the services offered at home; those followed by the SSIAD had the highest number of services and of weekly interventions. Hours of weekly services were two-fold higher in those with the informal coordination. At t12, there was an improvement in access to services for the network group with case management and an overall increase in the use of professional services at home with no significant difference between the three groups. CONCLUSION The use of social and primary health care services showed differences between the three gerontological coordinations. The one-year evolution in the use of home services was comparable between the groups without an explosion in the number of services in the network group with case management.

Abstract
There is a growing consensus that quality of life (QOL) is an important outcome for assessing the effectiveness of interventions for dementia, but there is no agreement about how to best measure it. Various approaches to QOL assessment have been employed to measure the QOL of persons with dementia, including patient self-report, caregiver proxy report and observational assessment by trained observers. Furthermore, several dementia-specific measures of QOL have been developed, and several generic measures of QOL have been used to assess QOL in dementia. However, to date, QOL has rarely been included as an outcome measure in clinical trials of pharmacotherapy for dementia. This manuscript reviews the current state of knowledge about QOL assessment in dementia.

Abstract
BACKGROUND AND PURPOSE There are obstacles for older people when reporting quality of life (QoL) in a survey format. The aim of this study was to explore the quality of data obtained on self-assessed QoL among older people with respect to modes of administration. METHOD AND RESULTS Approximately half of the QoL items showed significantly higher mean values in the mail sample than in the interview sample. Data suggest that there may be more vulnerability towards offering socially desirable answers. Problems with reduced energy and loss of memory affect both modes of administration. CONCLUSIONS This study demonstrates that investigating the mode of questionnaire administration among older people can be a valuable means by which to detect possible threats to data quality when interpreting QoL scores.

Abstract
PURPOSE To assess the acceptability, validity and inter-rater agreement of self- and family carer proxy ratings of the EQ-5D as a generic health-related quality of life (HRQOL) measure, in people with mild to moderate dementia (PwD) living in the community. A secondary aim was to identify the most important factors influencing self- and family carer proxy ratings of HRQOL, distinguishing between spouse and adult child caregiver ratings. METHODS Cross-sectional study of 488 dyads using the EQ-5D. Inter-rater agreement was examined using weighted kappa scores, and validity by investigating the association of self- and family carer ratings with clinical variables. Factors affecting HRQOL ratings were analysed using multivariate regression. RESULTS The response rate of the EQ-5D was satisfactory; however, agreement between self- and family carer ratings was poor. The most important predictors of PwD and carer ratings of the PwD's HRQOL were family carer ratings of activities of daily living and mood. Anxiety experienced by the PwD was a significant predictor of self-rated HRQOL, whereas depressive symptoms independently predicted family carer ratings. The type of the caregiving relationship influenced carer ratings of HRQOL, whereby sons and daughters rated HRQOL lower for the PwD compared with spousal caregivers. CONCLUSIONS People with mild to moderate dementia are able to rate their own HRQOL through a brief generic instrument; however, self-ratings consistently differ from family carer ratings, which should be acknowledged in cost-effectiveness analyses. Spouse caregivers rate HRQOL for the PwD more positively compared to adult children.

Abstract
BACKGROUND Health-related quality of life (HRQOL) in older adults is determined by personal conditions, as well as by the social and physical environment. The purpose of the present study was to describe the factors related to health conditions and residential environment that influence HRQOL of older adults. METHODS Data from 1815 cases came from three cross-sectional surveys on quality of life in older adults in Spain: non-institutionalized older adults (n = 1106), institutionalized older adults without dementia (n = 234) and institutionalized older adults with dementia (n = 475). Assessment instruments used were: Barthel Index, Short Portable Mental Status Questionnaire, Comorbidity Index, EQ-5D-3L (5 dimensions, EQ-index and EQ-VAS), and information about sociodemographic characteristics and social networks. Partial correlation and multivariate logistic regression analyses were carried out. RESULTS In group comparisons, institutionalized older adults showed a higher percentage of problems in the EQ-5D-3L dimensions than the non-institutionalized ones. Also, older adults with dementia presented less pain/discomfort and anxiety/depression than the other groups, but showed more problems in mobility, self-care and usual activities. EQ-Index showed a high association with functional independence, perceived health status and comorbidity. According to the logistic regression models, the Barthel Index was the most common determinant for most of EQ-5D-3L dimensions in all groups. CONCLUSION Institutionalized older adults with dementia presented lower HRQOL than the other groups. Functional independence, comorbidity and cognitive status were the main HRQOL determinants in all groups. Maintenance and improvement of the functional condition might be translated into a higher HRQOL of older adults.

Objective Proxy measures are an alternative source of data for care home residents who are unable to complete the health utility measure, but the agreement levels between residents and care home staff for the EQ-5D have not been investigated previously. The objective of the present study was to examine the inter-rater agreement levels for the reporting of EQ-5D by care home residents and staff, adjusting for the impact of clustering. Study Design and Setting The data consist of EQ-5D scores for 565 pairs of care home residents and proxies and quality-adjusted life-years (QALYs) for 248 pairs. Cluster-adjusted agreement was compared for the domains, index scores, and QALYs from the EQ-5D. Factors influencing index score agreement are also described. Results The results show poor to fair agreement at the domain level (cluster-adjusted Kappa −0.03 to 0.26) and moderate agreement at the score level (cluster-adjusted intra-class correlation coefficient [ICC] 0.44–0.50) and for QALYs (cluster-adjusted ICC 0.59). A higher likelihood of depression and lower cognitive impairment were both associated with smaller discrepancy between proxy and self-completed scores. Conclusion Proxies appear to be an acceptable source of data for index scores and QALYs but may be less reliable if individual domains are considered.

Abstract
BACKGROUND The EuroQoL-5D (EQ-5D) is a brief, multi-attribute, preference-based health status measurement. The objective of this study was to assess the validity and reliability of EQ-5D in older adults with and without dementia in Mexico City. METHODS The Study on Aging and Dementia in Mexico (SADEM) was a survey of 3101, Mexican adults (60 + years old). An in-home face-to-face interview was administered. EQ-5D using ranking to rate states on a 100-point visual analogue scale; Daily Living Activities (ADL), Instrumental Activities of Daily Living (IADL), Mini Mental State Examination (MMSE), Short Form of the quality of life survey (SF-36), and Charlson comorbility index were used for comparison. The validity and reliability of EQ-5D were tested. We identified states of health for direct valuation; state 11111 ("no problems") had to be included because it was essential to the reseating (onto a 0-1 scale) of the visual analogue scale data. We included all plausible combinations of levels across each of the five EQ-5D dimensions and evaluated any significant interaction effects and factorial designs, based on balanced complete blocks. RESULTS The EQ-5D was applied to 3101 older people, of whom 109 (3.4%) had dementia. The general reliability of EQ-5D for cases was 0.80 and for controls 0.76, for each dimension. We had a total of 103 combinations for controls and 45 for cases. The percentage for the state of health "no problems" (11111) for controls was 30.4%, and had the highest percentage of cases (8.8%). CONCLUSION The resulting valuations form the basis for clinical use and facilitate the interpretation and evaluation of health care.

Abstract
AIM To investigate the influence of health locus of control on physical function, quality of life, depression and satisfaction with care transition in a sample of older adults after a hospital admission. METHODS A total of 230 older adults referred for transition care after a hospital admission (mean length of stay 25.7 days, SD 17.2) were recruited into a randomized controlled intervention trial investigating the effect of specialized coaching compared with usual care. Older adults completed the multidimensional health locus of control (MHLC) survey at baseline. Self-rated quality of life, depression and physical function were assessed at baseline and 12 months using the EuroQol five-dimension, Geriatric Depression Scale (GDS) and Modified Barthel Index (MBI), respectively. RESULTS Results from hierarchical multiple regression analysis in 136 participants (70 usual care and 66 specialized care) with complete data showed that higher scores on the MHLC internal subscale were related to better quality of life, and better physical function in the usual care group at 12 months, but not depression or transition process satisfaction at 3 months. No relationships between MHLC subscales and outcome measures were observed in the specialized care group, where the coaching intervention might have precluded any relationship observed. CONCLUSIONS A stronger sense of personal control over health was associated with better maintenance of quality of life and physical function at 12 months in older adults undergoing usual care transition after acute hospitalization. Modification of control beliefs has the potential to promote resilience and impact on health outcomes in older adults during care transitions.

Abstract
Background Neuropsychiatric symptoms (NPS) frequently occur in patients with dementia. To date, prospective studies on the course of NPS have been conducted in patients with dementia in clinical centers or psychiatric services. The primary goal of this study is to investigate the course of NPS in patients with dementia and caregiver distress in primary care. We also aim to detect determinants of both the course of NPS in patients with dementia and informal caregiver distress in primary care. Methods/design This is a prospective observational study on the course of NPS in patients with dementia in primary care. Thirty-seven general practitioners (GPs) in 18 general practices were selected based on their interest in participating in this study. We will retrieve electronic medical files of patients with dementia from these general practices. Patients and caregivers will be followed for 18 months during the period January 2012 to December 2013. Patient characteristics will be collected at baseline. Time to death or institutionalization will be measured. Co-morbidity will be assessed using the Charlson index. Psychotropic drug use and primary and secondary outcome measures will be measured at 3 assessments, baseline, 9 and 18 months. The primary outcome measures are the Neuropsychiatric Inventory score for patients with dementia and the Sense of Competence score for informal caregivers. In addition to descriptive analyses frequency parameters will be computed. Univariate analysis will be performed to identify determinants of the course of NPS and informal caregiver distress. All determinants will then be tested in a multivariate regression analysis to determine their unique contribution to the course of NPS and caregiver distress. Discussion The results of this study will provide data on the course of NPS, which is clinically important for prognosis. The data will help GPs and other professionals in planning follow-up visits and in the timing for offering psycho-education, psychosocial interventions and the provision of care. In addition, these data will enlarge health professionals’ awareness of NPS in their patients with dementia.

Quality of life of nursing home residents with dementia: validation of the German version of the ICECAP-O. PLoS One 2014; 9:e92016.

Abstract
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 bivariate and multivariate stepwise regression analysis, comparing ICECAP-O scores between subgroups varying in dementia severity, care dependency, ADL status and demographic characteristics. Results Convergent validity between the ICECAP-O, EQ-5D+C, ADRQL and Barthel-Index scores was moderate to good (with correlations of 0.72, 0.69 and 0.53 respectively), but differed considerably between dimensions of the instruments. Discriminant validity was confirmed by finding differences in ICECAP-O scores between subgroups based on ADL scores (0.58 below 65 points on the Barthel-index and 0.80 above 65 points) and other characteristics. The ICECAP-O scores based on available tariffs were related to proxy characteristics gender (0.52 males versus 0.65 females) and work experience (0.61 below 2 years of experience versus 0.68 above 2 years). Discussion The results of this study suggest that the ICECAP-O is a promising generic measure for general Qol and capability of people with dementia living in a nursing home. Validity tests generally yielded favorable results. Work experience and gender appeared to influence proxy response, which raises questions regarding appropriate proxies, especially since the ICECAP-O may be completed by proxies relatively often. Further research is necessary to validate the German version of the ICECAP-O, with specific attention to proxy completion for people with dementia.

Abstract
BACKGROUND The possibility of living well with a long-term condition has been identified as centrally relevant to the needs of people living with dementia. Growing numbers of people with early-stage dementia are contributing accounts that emphasise the benefits of actively engaging in managing the condition. Self-management interventions share the common objectives of educating about the condition, optimising well-being, enhancing control over the situation and enabling people to take more responsibility for managing the condition. Benefits of such an approach can include improved knowledge, self-efficacy, health status, and better performance of self-management behaviours. However, there is only preliminary evidence that people with early-stage dementia can benefit from such interventions. METHODS This feasibility study involves the development of a self-management group intervention for people with early-stage Alzheimer's disease, vascular dementia or mixed Alzheimer's and vascular dementia. This study is a single-site pilot randomised-controlled trial. Forty-two people with early stage dementia, each with a caregiver (family member/friend), will be randomised to either the self-management group intervention or to treatment as usual.The self-management group intervention will involve eight weekly sessions, each lasting 90 minutes, held at a memory clinic in North Wales. All participants will be re-assessed three and six months post-randomisation. This study is intended to supply an early evaluation of the self-management intervention so that a full scale trial may be powered from the best available evidence. It will assess the feasibility of the intervention, the study design and the recruitment strategies. It will estimate the parameters and confidence intervals for the research questions of interest. The primary outcome of interest is the self-efficacy score of the person with dementia at three months post-randomisation. Secondary outcomes for the person with dementia are self-efficacy at six months post-randomisation and cognitive ability, mood and well-being at three and six months post-randomisation. Secondary outcomes for caregivers are their distress and stress at three and six months post-randomisation. The cost-effectiveness of the intervention will also be examined. DISCUSSION This study will provide preliminary information about the feasibility, efficacy and cost-effectiveness of a self-management group intervention for people in the early stages of dementia. TRIAL REGISTRATION Current Controlled Trials, ISRCTN02023181.

Abstract
Background Institutionalization is the most important milestone in the care of dementia patients. This study was aimed at identifying relevant predictors of institutionalization in a broad empirical context and interpreting them on the basis of the predictor model proposed by Luppa et al. [Dement Geriatr Cogn Disord 2008;26:65-78]. Methods At the start of this study, 357 patients with mild to moderate dementia were examined by their general practitioners, and a telephone interview was conducted with their caregivers. Four years later, the outcomes ‘institutionalization’ and ‘death’ were determined from health insurance data. Forty-one variables were examined for their predictive influence by univariate and multivariate Cox regression. Results The risk of institutionalization increased significantly (p ≤ 0.05) with older ages of patients [hazard ratio (HR) = 1.05] and caregivers (HR = 1.03), a higher educational level of the caregiver (HR = 1.83), greater use of community health services (HR = 1.59), greater caregiver burden (HR = 1.02), and when the caregiver and patient lived apart (HR = 1.97). Conclusion The results show that there is a multifactorial influence on institutionalization of dementia patients by sociodemographic, health-related, and psychological aspects as well as the care situation, thus validating the predictor model by Luppa et al. [Dement Geriatr Cogn Disord 2008;26:65-78]. Caregiver burden was found to be the strongest predictor accessible to interventions.

Abstract
AIM Measurement of health-related quality of life in people with dementia is a challenge, because of their special characteristics and the difficulties that this term entails itself. The present study aimed at assessing the psychometric properties of the EQ-5D rated by a familiar or a professional caregiver of institutionalized older adults with dementia. METHODS We analyzed the EQ-5D psychometric properties from 525 questionnaires rated by proxy, in a sample of institutionalized older adults with dementia. RESULTS The mean EQ-5D index score was 0.11 ± 0.38, and 51.54 ± 21.47 for the visual analog scale. The intraclass correlation coefficient was 0.72. Regarding internal consistency, Cronbach's alpha was 0.64, and the item-total correlation ranged from 0.33 to 0.53. Exploratory factor analysis identified a functional and a subjective factor, accounting for 67.35% of the variance. Convergent validity of EQ-5D with Quality of Life Alzheimer's Disease by proxy and Quality of Life in Late-stage Dementia scales was satisfactory (r = 0.36-0.58). The EQ-5D showed appropriate discriminative validity among patients grouped into several categories. Multiple linear regression models, using EQ-index and visual analog scale as dependent variables, identified dependence level, proxy characteristics, leisure and comorbidity as determinants of quality of life. CONCLUSIONS Despite some limitations in the more subjective dimensions, the proxy-rated EQ-5D showed satisfactory psychometric properties in the present study, suggesting that it is a valid and alternative instrument to assess quality of life in institutionalized older people with dementia.

Abstract
OBJECTIVE To compare a complex nondrug intervention including actively approaching counseling and caregiver support groups with differing intensity against usual care with respect to time to institutionalization in patients with dementia. METHODS Within this three-armed cluster-randomized controlled trial, 390 community-dwelling patients aged 65 years or older with physician-diagnosed mild to moderate dementia and their caregivers were enrolled via 129 general practitioners in Middle Franconia, Germany. The intervention included general practitioners' training in dementia care and their recommendation of support groups and actively approaching caregiver counseling. Primary study end point was time to institutionalization over 2 years. In addition, long-term intervention effects were assessed over a time horizon of 4 years. Secondary end points included cognitive functioning, (instrumental) activities of daily living, burden of caregiving, and health-related quality of life after 2 years. Frailty models with strict intention-to-treat approach and mixed linear models were applied to account for cluster randomization. Health care costs were assessed from the societal perspective. RESULTS After 2 (4) years, 12% (24%) of the patients were institutionalized and another 21% (35%) died before institutionalization. No significant differences between study groups were observed with respect to time to institutionalization after 2 and 4 years (P 0.25 and 0.71, respectively). Secondary end points deteriorated, but differences were not significant between study groups. Almost 80% of the health care costs were due to informal care. Total annual costs amounted to more than €47,000 per patient and did not differ between study arms. CONCLUSION The intervention showed no effects on time to institutionalization and secondary outcomes.

Abstract
Background Expectations held by patients and health professionals may affect treatment choices and participation (by both patients and health professionals) in therapeutic interventions in contemporary patient-centered healthcare environments. If patients in rehabilitation settings overestimate their discharge health-related quality of life, they may become despondent as their progress falls short of their expectations. On the other hand, underestimating their discharge health-related quality of life may lead to a lack of motivation to participate in therapies if they do not perceive likely benefit. There is a scarcity of empirical evidence evaluating whether patients’ expectations of future health states are accurate. The purpose of this study is to evaluate the accuracy with which older patients admitted for subacute in-hospital rehabilitation can anticipate their discharge health-related quality of life. Methods A prospective longitudinal cohort investigation of agreement between patients’ anticipated discharge health-related quality of life (as reported on the EQ-5D instrument at admission to a rehabilitation unit) and their actual self-reported health-related quality of life at the time of discharge from this unit was undertaken. The mini-mental state examination was used as an indicator of patients’ cognitive ability. Results Overall, 232(85%) patients had all assessment data completed and were included in analysis. Kappa scores ranged from 0.42-0.68 across the five EQ-5D domains and two patient cognition groups. The percentage of exact correct matches within each domain ranged from 69% to 85% across domains and cognition groups. Overall 40% of participants in each cognition group correctly anticipated all of their self-reported discharge EQ-5D domain responses. Conclusions Patients admitted for subacute in-hospital rehabilitation were able to anticipate their discharge health-related quality of life on the EQ-5D instrument with a moderate level of accuracy. This finding adds to the foundational empirical work supporting joint treatment decision making and patient-centered models of care during rehabilitation following acute illness or injury. Accurate patient expectations of the impact of treatment (or disease progression) on future health-related related quality of life is likely to allow patients and health professionals to successfully target interventions to priority areas where meaningful gains can be achieved.

Abstract
Alzheimer's disease (AD) is a chronic, progressive, neurodegenerative disease that places a heavy burden on people with the condition, their families and carers, health care systems and society in general. Health-related quality of life (HR-QOL) in patients deteriorates as the cognitive, behavioural and functional symptoms of AD develop. The human and financial cost of AD is forecast to grow rapidly as populations age, and those responsible for planning and financing health care face the challenge of allocating increasingly scarce resources against current and future interventions targeted towards AD. These include calls for early detection and diagnosis, preventative strategies, new medications, residential care, supportive care, and meeting the needs of carers as well as patients. Health care funders in many health systems now require a demonstration of the value of new interventions through a comparison of benefits in terms of improvements in HR-QOL and costs relative to those of competing or existing practices. Changes in HR-QOL provide the basis for the calculation of the quality-adjusted life-year (QALY), a key outcome used in economic evaluations to compare treatments within and between different disease conditions. The objective of this systematic review was to provide a summary of the published health state values (utilities) for AD patients and their carers that are currently available to estimate QALYs for use in health economic evaluations of interventions in AD. The health care literature was searched for articles published in English between 2000 and 2011, using keywords and variants including 'quality-adjusted life years', 'health state indicators', 'health utilities' and the specific names of generic measures of HR-QOL and health state valuation techniques. Databases searched included MEDLINE, EMBASE, NHS EED, PsycINFO and ISI Web of Science. This review identified 12 studies that reported utility values associated with health states in AD. Values for AD health states categorized according to cognitive impairment (where 1 = perfect health and 0 = dead) ranged from mild AD (0.52-0.73) to moderate AD (0.30-0.53) to severe AD (0.12-0.49). Utility values were almost all based on two generic measures of HR-QOL: the EQ-5D and Health Utility Index mark 2/3 (HUI2/3). There were no health state values estimated from condition- or disease-specific measures of HR-QOL. The review also identified 18 published cost-utility analyses (CUAs) of treatments for AD. The CUAs incorporated results from only three of the identified health state valuation studies. Twelve CUAs relied on the same study for health state values. We conclude that the literature on health state values in AD is limited and overly reliant on a single symptom (cognition) to describe disease progression. Other approaches to characterizing disease progression in AD based on multiple outcomes or dependency may be better predictors of costs and utilities in economic evaluations. Patient and proxy ratings were poorly correlated, particularly in patients with more advanced AD. However, proxy ratings displayed the validity and reliability across the entire range of AD severity needed to detect long-term changes relevant to economic evaluation. Further longitudinal research of patient and carer HR-QOL based on multidimensional measures of outcome and utilities is needed.

[PMID: 22229093 PMCID: PMC3250621 DOI: 10.4061/2011/682470] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2011] [Accepted: 10/11/2011] [Indexed: 11/20/2022] Open
Abstract
Objectives. The objectives of this study were to elicit health utility scores for moderate Alzheimer's disease (AD) using members of the general public. Methods. Five-hundred Canadians were chosen randomly to participate in a telephone interview. The EQ-5D was administered to estimate the health utility score for respondents' current health status (i.e., no AD) and for a hypothetical moderate AD health state. Regression analyses were conducted to explain the perceived utility decrement associated with AD. Results. The mean age of the respondents was 51 years, 60% were female, and 42% knew someone with AD. Respondents' mean EQ-5D scores for their current health status and a hypothetical moderate AD were 0.873 (SD: 0.138) and 0.638 (SD: 0.194), respectively (P < 0.001). Age, gender, and education were significant factors explaining this decrement in utility. Conclusion. Members of the general public may serve as an alternative to patients and caregivers in the elicitation of health-related quality of life in AD.

Abstract
BACKGROUND The study investigated the change in proxy rated quality of life (QoL) of a large cohort of home living patients with Alzheimer's disease (AD) over a period of 36 months. METHODS The sample consisted of 102 patients with mild AD and their primary caregivers from the Danish Alzheimer's Disease Intervention Study. QoL was assessed with the proxy-rated (primary caregivers) Quality of Life in Alzheimer Disease scale (QOL-AD) and the EuroQuol Visual Analogue Scale (EQ-VAS) scale. The Cornell Scale for Depression in Dementia (CSDD), Alzheimer's Disease Cooperative Study, Activities of Daily living Inventory (ADCS-ADL), Mini-Mental State Examination (MMSE) and Neuropsychiatric Inventory (NPI-Q) were also applied. Evaluations were conducted at baseline and at 12 and 36 months follow-up. RESULTS There was a significant decline in mean QoL assessed by both the QOL-AD and the EQ-VAS (p < 0.001). There were vast individual differences in the QoL scores on both scales at 12 and 36 months' follow-up. Mean change from baseline in QOL-AD was significantly associated with change in CSDD, ADCS-ADL and MMSE scores at 12 months and with ADCS-ADL score at 36 months. CONCLUSION QoL is a subjective concept and may not be influenced by the degree of cognitive dysfunction. Future studies should investigate the factors for individual variations in order to understand the nature of change of QoL in AD and the wide variation in QoL scores over time.

Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) are common manifestations of Alzheimer' s disease (AD). OBJECTIVE To examine the prevalence and significance of NPS in very mild and mild AD patients with emphasis on their influence on the well-being of the patients and their caregivers. METHODS The participants were 240 patient-caregiver dyads who participated in a prospective, controlled rehabilitation study (ALSOVA). Three Quality of Life (QoL) instruments were used; generic 15D, disease-specific QoL-AD and Visual Analog Scale (VAS). The disease-specific QoL-AD was both self-rated and caregiver rated. Other scales used were Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), ADCS-ADL, Neuropsychiatric Inventory (NPI) and Beck Depression Inventory (BDI). RESULTS NPS were present in 76.5% of patients with very mild AD (CDR 0.5) and in 84.9% of patients with mild to moderate AD (CDR 1). The most frequent symptoms were apathy, depression, irritability, and agitation. The strongest predictor of self-reported QoL-AD scores was depressive symptoms whereas functional decline and presence of NPS predicted poor caregiver ratings of patients' QoL. However, caregiver depression also influenced significantly their ratings. CONCLUSION NPS are common even in the early stages of AD. NPS were significantly associated with caregiver assessment of the patient's QoL but not with patients' self-assessed QoL. Depression decreases QoL, but may remain unrecognized in AD patients, emphasizing the need for careful and structured assessment of NPS before deciding on the appropriate treatment.

Abstract
OBJECTIVES This article analyzes published studies on the application of the EQ-5D for the assessment of quality of life in patients with dementia and their carers. The EQ-5D, a generic instrument for measuring health-related quality of life, is widely used for economic evaluation in many areas of health research. However, there is considerable debate about the appropriateness of the EQ-5D for people with impaired cognition. METHODS We conducted a systematic review of research studies published in the past 10 years that either used the EQ-5D as an outcome measure or investigated different aspects of the performance of the EQ-5D in studies of dementia. RESULTS This study demonstrates that despite good feasibility and reliability of the EQ-5D instrument, there are problems with the validity of self-rated data because of a lack of association between patient and proxy ratings. There is a substantial ceiling effect for patient ratings. The visual analogue scale has poor reliability, even in patients with mild and moderate dementia. Different proxies (e.g., family carers, institutional carers, and health-care professionals) provide different ratings for patients' health. CONCLUSION Careful selection of assessment mode and appropriate proxies is important to ensure the EQ-5D validity in studies of patients with dementia. Because the cost of informal patient care represents a significant proportion of total costs of dementia treatment, the impact of dementia on carer's quality of life should be included in economic evaluation.

Abstract
BACKGROUND Quality of life in dementia has been studied in clinical settings. There is less population-based research on life satisfaction and cognition. OBJECTIVES (1) To compare the overall life satisfaction (LS), LS with material circumstances (LS (material)), and LS with social circumstances (LS (social)) of older adults with no cognitive impairment, with cognitive impairment no dementia (CIND), and with dementia; (2) To examine the effect of cognition on LS across a broad spectrum of cognition; and (3) To explore the effect of factors such as depressive symptoms, functional impairment, education, and social support. POPULATION 1620 community-dwelling older adults with a mini-mental state examination (MMSE) score > 10, sampled from a representative list were interviewed. MEASURES Age, gender, education, social networks, and social supports were all self-reported. The MMSE, the Centre for Epidemiologic Studies-Depression (CES-D), and the Older Americans Resource Survey (OARS) were used. Dementia was diagnosed by clinical examination using DSM-IIIR criteria. LS was measured using the Terrible-Delightful Scale. Factor analysis identified two factors: LS (material), and LS (social). A global item measuring overall LS was also used. RESULTS Those with dementia and CIND had lower LS than those with normal cognition, but the effect was relatively small. There was a gradient in LS which extended into the normal range of cognition. Depressive symptoms and functional status were strongly associated with LS. CONCLUSIONS Cognition is associated with LS, but the effect is fairly small. Most older adults are satisfied with life.

Abstract
PURPOSE Due to their cognitive impairment, the health-related quality of life (HRQoL) of patients with dementia is often rated by proxies. This study aims to analyse the psychometric properties of the EQ-5D applied to patients with mild to moderate dementia and their family caregivers. METHODS Three hundred and ninety patients and their caregivers were asked to assess the patients' HRQoL using the EQ-5D. The German population-based time trade-off values were used to calculate utility weights. Acceptance, discriminative ability, construct validity, inter-rater agreement and responsiveness were tested. Factors that could have an impact on inter-rater agreement were analysed using a multivariate regression. RESULTS Five per cent of patients did not fill out the EQ-5D. The response rate of caregivers and of patients with mild dementia was higher than that of patients with moderate dementia. There were no floor or ceiling effects. The test results of the caregivers concerning construct validity and responsiveness were better than those of the patients. The inter-rater reliability was not satisfactory either on the dimension level or on the utility score level. Caregivers gave the patients' HRQoL significantly lower ratings than did the patients themselves. Better abilities of the patient to perform activities of daily living and a lower subjective burden of the caregiver were associated with a higher inter-rater agreement. CONCLUSIONS The study showed that the EQ-5D is especially applicable to patients with mild dementia and their caregivers as proxies. However, there are important differences between patient and proxy ratings, even in cases of mild dementia, at the dimension level as well as utility score level, which should be considered in the interpretation of quality of life scores.

Abstract
Chronic diseases have a long-term negative impact on quality of life (QOL). Decreased QOL is associated with increased financial burden on healthcare systems and society. However, few publications have investigated the impact of glaucoma on patients' QOL in comparison with other chronic diseases observed in patients with similar demographic characteristics. To this end, a systematic literature search to assess QOL in glaucoma and three other chronic diseases (osteoporosis, type 2 diabetes mellitus and dementia) was performed. A total of 146 publications were identified that reported QOL using six commonly used generic QOL instruments: 36-, 12- and 20-item Short-Form Health Surveys (SF-36, -12 and -20), EuroQoL (EQ-5D), Sickness Impact Profile (SIP) and the Health Utilities Index-Mark III (HUI-III). The publication breakdown was as follows: glaucoma (10%), osteoporosis (26%), diabetes (52%) and dementia (12%); one publication assessed QOL in glaucoma, diabetes and dementia. QOL was affected to a similar or slightly lesser degree by glaucoma than by osteoporosis, diabetes or dementia. Among the publications reporting SF-36, -12 and -20 evaluations, physical component scores were generally lower than mental component scores across all diseases. QOL was affected more in patients with glaucoma than in demographically matched non-glaucomatous controls according to SF-20 assessment. EQ-5D and SIP results showed that QOL decreased as the severity of glaucoma increased. Patients with glaucoma had the lowest scores on the SIP instrument, indicating better QOL than patients with osteoporosis or diabetes (no data were available on dementia). The HUI-III instrument identified poorer QOL in patients with dementia than other diseases, probably due to cognitive deficits. However, for some of the instruments, data were scarce, and interpretation of the results should be conservative. Although there are limited published QOL studies in glaucoma, its impact on QOL appears to be broadly similar to that of other serious chronic diseases. Development of a QOL instrument that measures vision-specific and general health aspects would better document the impact of glaucoma on QOL and would facilitate comparisons with other chronic disease states.
