Abstract
BACKGROUND Some hospital admissions of nursing home residents (NHRs) might be attributed to inadequate interprofessional collaboration. To improve general practitioner-nurse collaboration in nursing homes (NHs), we developed an intervention package (interprof ACT) in a previous study. OBJECTIVE To assess the impact of interprof ACT on the proportion of hospitalisation and other clinical parameters within 12 months from randomisation among NHRs. METHODS Multicentre, cluster randomised controlled trial in 34 German NHs. NHRs of the control group received usual care, whereas NHRs in the intervention group received interprof ACT. Eligible NHs had at least 40 long-term care residents. NHs were randomised 1:1 pairwise. Blinded assessors collected primary outcome data. RESULTS Seventeen NHs (320 NHRs) were assigned to interprof ACT and 17 NHs (323 NHRs) to usual care. In the intervention group, 136 (42.5%) NHRs were hospitalised at least once within 12 months from randomisation and 151 (46.7%) in the control group (odds ratio (OR): 0.82, 95% confidence interval (CI): [0.55; 1.22], P = 0.33). No differences were found for the average number of hospitalisations: 0.8 hospitalisations per NHR (rate ratio (RR) 0.90, 95% CI: [0.66, 1.25], P = 0.54). Average length of stay was 5.7 days for NHRs in the intervention group and 6.5 days in the control group (RR: 0.70, 95% CI: [0.45, 1.11], P = 0.13). Falls were the most common adverse event, but none was related to the study intervention. CONCLUSIONS The implementation of interprof ACT did not show a statistically significant and clinically relevant effect on hospital admission of NHRs.

Abstract
OBJECTIVES This study aims to validate the Japanese version of Quality of Life-Alzheimer's Disease for Nursing Homes (QOL-AD NH). This is the modified version of QOL-AD, initially developed for residents living with dementia in long-term care settings. METHODS Psychometric assessment was conducted in a sample of 101 residents and their professional care staff to obtain self-ratings and proxy-ratings of QOL, respectively. Residents' behavior was observed using Dementia Care Mapping (DCM) method, and their mood/engagement (ME) value was evaluated as a proxy measure of QOL. RESULTS Self-ratings were higher than proxy-ratings (t = 10.22, p<.001), with moderate correlation (r=.51, p<.001) and strong internal consistency (α=.87 for both). The exact agreement between the two groups was 38.23%. Convergent validity was confirmed with ME value and positive engagements of DCM. Exploratory factor analysis was performed for further validity testing. Three factors - self and life overall, social environment, and physical and psychological health, accounted for 85.9% of the total variance with Cronbach's α of .87, .73, .90, respectively. CONCLUSION Using a validated Japanese version of the QOL-AD NH may help assess the QOL of older residents living in long-term care settings to improve the continuum of care for dementia.

Comparing the psychometric properties of EQ-5D-3L and EQ-5D-5L proxy ratings by informal caregivers and a health professional for people with dementia. Health Qual Life Outcomes 2022; 20:140. [PMID: 36199138 PMCID: PMC9535990 DOI: 10.1186/s12955-022-02049-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 09/16/2022] [Indexed: 11/25/2022] Open
Abstract
Background Assessing health-related quality of life (HRQoL) among persons with dementia poses several challenges due to cognitive decline and limited perception. As a result, proxy ratings by family members or health professionals are used. The EQ-5D is the most commonly used generic and preference-based HRQoL instrument. Methodological drawbacks of the three-level version (EQ-5D-3L) prompted the development of the five-level version (EQ-5D-5L) by expanding the range in the domains. However, no comparison of the psychometric properties of both versions and different proxy ratings exist so far. Therefore, the objective of this study was to compare the psychometric properties of the EQ-5D-5L and EQ-5D-3L by application of different proxy ratings in dementia. Methods The EQ-5D-3L and -5L were completed by n = 52 family caregivers and one care manager at baseline and three and six months later. In total, 106 caregiver and 133 care manager proxy ratings were completed. The EQ-5D-3L and 5L were evaluated in terms of acceptability (missing values), agreement, ceiling effects, redistribution properties and inconsistency, and informativity (Shannon, H', and Shannon Evenness, J', indices) as well as convergent and discriminative validity. Results Mean proxy index scores were higher for the 5L than the 3L. Missing values occurred less frequently in both proxy ratings and versions (< 1%). Agreement between both measures was high but higher in caregiver than care-manager ratings (ICC 0.885 vs. 0.840). The relative ceiling effect decreased from the 3L to the 5L, more intensively in the care-manager (75%) than the caregiver rating (56%). Inconsistency between both versions was low. Informativity increased from the 3L to the 5L version, nearly equally in both proxy ratings. The 5L also demonstrated a better discriminative ability and convergent validity than the 3L, especially in the caregiver rating. Conclusion Compared to the EQ-5D-3L, the EQ-5D-5L had higher feasibility and acceptability and was slightly superior by a reduction of ceiling effects and an improvement in informativity, discriminative ability and convergent validity. Proxy ratings by informal caregivers overall demonstrated better psychometric properties than professional care-manager ratings.

Abstract
BACKGROUND No specific scale to measure Quality of Life in Alzheimer's Disease in Nursing Homes (QoL-AD NH) exists in French. We aimed to translate and culturally adapt the QoL-AD NH participant scale into a French version and evaluate its psychometric properties with residents in French nursing homes (EHPAD). METHODS First, the QoL-AD NH was cross-culturally adapted into French according to guidelines. Secondly, a convenience group of residents with mild to moderate dementia answered the Folstein's test and the QoL-AD NH. They also answered the Dementia Quality of Life and the Geriatric Depression Scale to test convergent and divergent validity. Known-group validity was tested with a comparison group of residents without dementia. Exploratory Structural Equation Modeling (ESEM) was used after Exploratory Factor Analysis (EFA) to identify factors and measure invariance across age and mental state groups. Reliability (internal consistency, McDonald's omega and test-retest) were also measured. RESULTS Following successful adaptation of the QoL-AD NH, 174 residents (mean age 86.6) from 7 nursing homes with mild to moderate dementia participated in the validation study. We retained a 3-factor model of the scale after ESEM identifying: "Intra & interpersonal environment-related QoL", "Self-functioning-related QoL" and "Perceived current health-related QoL" that were invariant across age and mental state groups. The QoL-AD NH had acceptable convergent (ρ range 0.24-0.53) and divergent validity (ρ range - 0.43 to - 0.57) and good known-group validity with 33 residents without dementia (t(205) = 2.70, p = .007). For reliability, the results revealed very good and adequate internal consistency (α = 0.86 for total scale and ≥ 0.71 for subscales). All total omega values exceeded the threshold 0.70. The hierarchical omega was 0.50, supporting the multidimensionality of the scale. Hierarchical omega subscale values exceeded the minimal level 0.50 except for the third factor, although reliable, would deserve more items. Test-retest was good with ICC (3,1) = 0.76. CONCLUSIONS The QoL-AD NH French participant version has globally good reliability and validity for evaluating residents' quality of life. However, further studies must rework and confirm the factor structure, test sensitivity to change and responsiveness.

Abstract
BACKGROUND Assessing health-related quality of life in dementia poses challenges due to patients' cognitive impairment. It is unknown if the newly introduced EQ-5D five-level version (EQ-5D-5L) is superior to the 3-level version (EQ-5D-3L) in this cognitively impaired population group. OBJECTIVE To assess the psychometric properties of the EQ-5D-5L in comparison to the EQ-5D-3L in patients living with dementia (PwD). METHODS The EQ-5D-3L and EQ-5D-5L were assessed via interviews with n = 78 PwD at baseline and three and six months after, resulting in 131 assessments. The EQ-5D-3L and EQ-5D-5L were evaluated in terms of acceptability, agreement, ceiling effects, redistribution properties and inconsistency, informativity as well as convergent and discriminative validity. RESULTS Mean index scores were higher for the EQ-5D-5L than the EQ-5D-3L (0.70 versus 0.64). Missing values occurred more frequently in the EQ-5D-5L than the EQ-5D-3L (8%versus 3%). Agreement between both measures was acceptable but poor in PwD with moderate to severe cognitive impairment. The index value's relative ceiling effect decreased from EQ-5D-3L to EQ-5D-5L by 17%. Inconsistency was moderate to high (13%). Absolute and relative informativity increased in the EQ-5D-5L compared to the 3L. The EQ-5D-5L demonstrated a lower discriminative ability and convergent validity, especially in PwD with moderate to severe cognitive deficits. CONCLUSION The EQ-5D-5L was not superior as a self-rating instrument due to a lower acceptability and discriminative ability and a high inconsistency, especially in moderate to severe dementia. The EQ-5D-3L had slightly better psychometric properties and should preferably be used as a self-rating instrument in economic evaluations in dementia.

Effects of strategies to improve general practitioner-nurse collaboration and communication in regard to hospital admissions of nursing home residents (interprof ACT): study protocol for a cluster randomised controlled trial. Trials 2020; 21:913.

Abstract
BACKGROUND In Germany, up to 50% of nursing home residents are admitted to a hospital at least once a year. It is often unclear whether this is beneficial or even harmful. Successful interprofessional collaboration and communication involving general practitioners (GPs) and nurses may improve medical care of nursing home residents. In the previous interprof study, the six-component intervention package interprof ACT was developed to facilitate collaboration of GPs and nurses in nursing homes. The aim of this study is to evaluate the effectiveness of the interprof ACT intervention. METHODS This multicentre, cluster randomised controlled trial compares nursing homes receiving the interprof ACT intervention package for a duration of 12 months (e.g. comprising appointment of mutual contact persons, shared goal setting, standardised GPs' home visits) with a control group (care as usual). A total of 34 nursing homes are randomised, and overall 680 residents recruited. The intervention package is presented in a kick-off meeting to GPs, nurses, residents/relatives or their representatives. Nursing home nurses act as change agents to support local adaption and implementation of the intervention measures. Primary outcome is the cumulative incidence of hospitalisation within 12 months. Secondary outcomes include admissions to hospital, days admitted to hospital, use of other medical services, prevalence of potentially inappropriate medication and quality of life. Additionally, health economic and a mixed methods process evaluation will be performed. DISCUSSION This study investigates a complex intervention tailored to local needs of nursing homes. Outcomes reflect the healthcare and health of nursing home residents, as well as the feasibility of the intervention package and its impact on interprofessional communication and collaboration. Because of its systematic development and its flexible nature, interprof ACT is expected to be viable for large-scale implementation in routine care services regardless of local organisational conditions and resources available for medical care for nursing home residents on a regular basis. Recommendations will be made for an improved organisation of primary care for nursing home residents. In addition, the results may provide important knowledge and data for the development and evaluation of further strategies to improve outpatient care for elderly care-receivers.

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 The Quality of Life-Alzheimer's Disease (QoL-AD) scale is a widely used measure of quality of life (QoL) in dementia. Although the instrument has been validated in several languages, the psychometric properties of the German self-report version have not yet been analyzed. OBJECTIVE This study examines the internal consistency, test-retest reliability, and construct validity of the German QoL-AD self-report scale. METHODS The sample included 30 patients suffering from mild to moderate Alzheimer's disease or vascular dementia (19 females; mean age 77.3 years; mean Mini-Mental State Examination (MMSE) score 19.7 points). To determine test-retest reliability, the QoL-AD self-report scale was re-administered four to seven days apart. For construct validity analysis, the Dementia Quality of Life instrument (DQoL), Geriatric Depression Scale (GDS), MMSE, and an adapted short form of the Neuropsychiatric Inventory (NPI) were used. RESULTS The German QoL-AD self-report scale shows an internal consistency of α= 0.79 and a test-retest reliability of r = 0.75 (p < 0.01). Regarding construct validity, there was a significant positive correlation between the total scores of the QoL-AD and DQoL (r = 0.47, p < 0.05). The analysis revealed no significant correlations with the GDS or the adapted NPI. No association could be observed between the QoL-AD and the MMSE (r = 0.01), confirming divergent validity. CONCLUSION The results indicate that the German QoL-AD self-report scale is a suitable instrument for assessing QoL in patients suffering from mild to moderate dementia, thus supporting its use in clinical practice and research.

Abstract
OBJECTIVES To assess the acceptability and validity of the 3 levels of the EQ-5D (EQ-5D-3L) compared with the Quality of Life in Alzheimer's Diseases (QoL-AD) in patients living with dementia. METHODS The analysis was based on 560 dyads of persons with dementia and their caregivers of the multicenter observational study of dementia care networks in Germany (DemNet-D). Health-related quality of life was assessed by face-to-face interviews using the EQ-5D-3L (self-rating) and the QoL-AD (self- and proxy-rating). The number of missing values, the score ranges (observed vs possible range) and the floor and ceiling effects were used to assess the acceptability. We used one-way analyses of variance and multivariate linear regression models to evaluate the discriminative ability. The convergent validity was assessed using Spearman's correlation coefficient (rs) and multivariate regression models. RESULTS The EQ-5D index had a higher response rate (89% vs 84%) and a comparable floor (>1%) but a higher ceiling effect (18% vs >1%) compared with the QoL-AD. Both measures can significantly differentiate between different stages of general health, instrumental activities of daily living, and depression. The EQ-5D index and the visual analog scale self-rating scores strongly correlated with the QoL-AD self-rating (rs = 0.644 and 0.553, respectively) but not with the proxy-rating score (rs = 0.314 and rs = 0.170, respectively), which was confirmed by multivariate regression analyses. CONCLUSION The results satisfy acceptability, discriminative ability, and convergent validity for moderately cognitively and functionally impaired patients living with dementia. The EQ-5D-3L performed comparably with the QoL-AD, and could, therefore, be used in economic evaluations in dementia. The differences between self- and proxy-ratings should be evaluated and considered in the interpretation of health-related quality of life scores.

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.

Abstract
Previous studies showed that the Confusion Assessment Method based delirium severity evaluation tool (CAM-S) had good reliability and validity. However, there is no Chinese version of the CAM-S. Therefore, we set out to perform a prospective investigation in older Chinese patients who had total joint replacement surgery under general anesthesia in Tenth People's Hospital in Shanghai, P.R. China. A total of 576 participants, aged 60 years or older, were screened, 179 participants were enrolled, and 125 of them were included for the final analysis. Pre-operative evaluations were conducted one day before the surgery. Postoperative evaluations were conducted twice daily from postoperative day 1 to day 3. The incidence of postoperative delirium was 24.8%. The Chinese version of CAM-S [including a Short Form (CAM-S Short Form) and a Long Form (CAM-S Long Form)] had an optimal reliability reflected by internal consistency (Cronbach's α= 0.748 and 0.839 for CAM-S Short Form and CAM-S Long Form respectively), split-halves reliability (Pearson correlation coefficient = 0.372 and 0.384 for CAM-S Short Form and CAM-S Long Form respectively), and inter-rater reliability (intra-class correlation coefficients = 0.629 and 0.945 for CAM-S Short Form and CAM-S Long Form respectively). Additionally, the Chinese version of CAM-S also showed a good discriminate validity. The domain scores of CAM-S were inversely correlated with corresponding domain scores of the MMSE. Finally, a receiver operating characteristic (ROC) analysis obtained an optimal cutoff point of 2.5 for CAM-S Short Form and 3.5 for CAM-S Long Form in recognizing delirium diagnosed by CAM. The areas under the ROC were 0.989 (95% CI 0.972 - 1.000, p < 0.001) and 0.964 (95% CI 0.946 - 0.982, p < 0.001), respectively. These data suggest that the Chinese version of CAM-S has good reliability and validity in evaluating postoperative delirium in geriatric Chinese patients and may be a useful tool to assess the severity of delirium.
