Background: Assessing the built environment in nursing homes is part of several established instruments. Measurements are primarily published in English, so there is a need for cross-cultural adaptation to be able to use them in other countries. This procedure should be carried out alongside translation guidelines to ensure successful adaptation not only for assessments that capture complex constructs, such as the built environment, but also for assessments to be applied in healthcare in general. Objective: This article presents different approaches to adopt the Australian Environmental Assessment Tool—High Care (EAT-HC) based on the World Health Organization (WHO) guidelines for instrument translation. The comparison of these processes should provide implications for further adaptations of the instrument. Methods: The adaptation processes carried out in Germany, Japan, and Singapore were compared using thematic analysis. Steps taken to achieve linguistic validation and to adopt the tool were analyzed qualitatively in the context of overarching needs for adjustment. Results: Every perspective adapted the WHO guidelines for their respective purposes of applying the EAT-HC. The order of steps varied, but elements to validate the results with the instruments’ creators and to ensure validity were included in all three countries. For items that might be challenging, we detected possible reasons that might help future adaptors manage this process more efficiently. Conclusion: The EAT-HC benefits from adaptation alongside the WHO guidelines in terms of enhancing the quality of translation and feasibility of application. Individual supplementary adaptation steps allow the identification of culture-specific needs for application in other countries.

This study reports on the cultural adaptation of the Environmental Assessment Tool-Higher Care (EAT-HC) in Germany, Japan, and Singapore. The purpose is to compare the content validity assessment, focusing on common and unique challenges encountered by each nation. In Germany, the security through environmental safety features and segregation of residents is highly debatable. Japan's challenge is for gerontologists to work closely with facility directors and architects to balance the cultural aspects of design. In Singapore, there is a gap in dementia design literacy for healthcare practitioners and designers. Identifying culturally sensitive aspects benefits further adaptation of the EAT-HC worldwide.

Background: This article describes the development of the Singapore Environmental Assessment Tool (SEAT), a culturally appropriate, usable, reliable, and valid assessment tool designed to evaluate the extent to which the built environment in Singaporean aged care facilities is able to support the provision of high levels of care to people living with dementia. Methods: A multistage sequential mixed methods approach was carried out involving 16 raters in Stage 1 and six raters in Stage 2 using a culturally adapted English version of the Environmental Audit Tool–High Care (EAT-HC) in eight nursing homes. The first stage captured qualitative data on cultural sensitivities and usability of the tool. The SEAT was improved based on the findings, and in the second stage, the usability and psychometric properties of the modified tool were again assessed. Usability was determined by data collected via the System Usability Scale and the Questions to Assess Barriers and Facilitators survey. Psychometric properties were examined by the calculation of percentage agreement, item-level interrater agreement was measured using Fleiss’s κ, and Cronbach’s α was used to measure the internal consistency of the subscale scores. Results: The culturally adapted SEAT was found to have an acceptable level of usability and moderate level of reliability among subscales. Conclusion: The study indicated that the tool is reliable and valid when completed by users with knowledge of dementia-enabling environments. For the tool to be used with confidence education in the application of principles of design to the design of environments for people living with dementia is recommended prior to its use.

Objectives: This study investigated the level of acceptance in Singapore of the eight principles of design underpinning the Environmental Assessment Tool–High Care (EAT-HC), which is commonly used in Australia to evaluate environments for the care of people living with dementia. A secondary goal was to identify topics particularly relevant to the Singaporean context, which are not included in the Australian EAT-HC. Background: This study was undertaken in preparation for the development of a Singaporean version of the Australian EAT-HC. Methods: Discussions from 23 focus groups involving 150 family caregivers, aged care staff, administrators, and architects were recorded and thematically analyzed to identify the characteristics of the principles underpinning the EAT-HC that are unlikely to be relevant in a Singaporean version and to identify additional topics required to tailor it to reflect the Singaporean culture. The thematic analysis was supplemented with quantitative data obtained through the use of simple Likert-type scales measuring the appropriateness of each principle in the Singaporean context. Results: The principles of design that underpin the EAT-HC were highly accepted by participants and provided a framework for a systematic exploration of Singaporean residential care for people with dementia. Some topics of particular relevance to Singapore were identified. These can be subsumed by the principles without the need for the principles to be changed. Conclusion: The results support the use of the design principles underpinning the EAT-HC as the foundation of a tool for the evaluation of Singaporean dementia facilities.

Background:This scoping review explores the characteristics of the current built environment used to accommodate people with dementia in East and Southeast Asia. It is structured around the eight principles of design found in the Environmental Audit Tool High-Care. In addition, the review examines the level of knowledge and other influences contributing to the development of nursing homes in the region.Methods:The review was carried out utilizing the methodological framework recommended by Arksey and O'Malley. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses provided an overarching structural framework for the reporting process and the Population, Intervention, Comparison, Outcomes, and Context framework defined the scope of the review and focused on the research question. Six databases were accessed for the search, and 1,846 publications between 2001 and 2015 were retrieved.Results:A total of 48 articles from 9 countries met the inclusion criteria. All articles presented discussions that fundamentally included at least one principle of design and with some including all principles. The most prevailing principle discussed, found in 59% of all the articles was the need for familiarity for residents in the environmental design of facilities.Conclusions:The review found that the eight principles of design, when applied with cultural sensitivity in countries in East and Southeast Asia can identify gaps in knowledge of the design for dementia enabling environments and suggest areas for improvement. An assessment tool based on the principles of design will be able to provide a guide for stakeholders in the design, development, or modification of nursing home environments.

Japan is a super-ageing society that faces pressures on its aged care system from a growing population of older adults. Naturalistic observations were undertaken at eight aged care facilities in central and northern Japan to explore how aged care is configured. Four aspects of contemporary provision were identified that offer potential gains in quality of life and health. The Japanese government mandates that aged care facilities must employ a qualified nutritionist to oversee meal preparation, fostering optimal dietary intake. A concept of life rehabilitation seeks to maximise physical and cognitive performance, with possible longevity gains. Low staff to resident ratios are also mandated by the Japanese government to afford residents high levels of interpersonal care. Finally, Japanese facilities prioritise experiences of seasonality and culture, connecting frail older people to the world beyond their walls.

The purpose of this study is to investigate the mechanism of protein stabilization by sugars in the solid state. That is, explore whether the stabilization is controlled by "glass dynamics" or by native structure preservation through "specific interaction" between sugars and protein. The IgG1 antibody (150 kD) and recombinant human serum albumin (rHSA) (65 kD) were formulated with sorbitol, trehalose, and sucrose. Degradation of lyophilized formulations was quantified using size exclusion (SEC) and ion-exchange chromatography (IEX). The secondary structure of the protein in these formulations was characterized using Fourier Transform Infrared (FTIR) spectroscopy. The molecular mobility, as measured by the stretched relaxation time (tau(beta)) was obtained by fitting the modified stretched exponential (MSE) equation to the calorimetric data from the Thermal Activity Monitor (TAM). Compared with sucrose and trehalose, sorbitol could only slightly protect the protein against aggregation and had no effect on chemical degradation. The chemical degradation and aggregation rates of the protein decreased when the weight ratio of sucrose to protein increased from 0 to 2:1. Storage stability of the proteins showed a reasonably good correlation with the degree of retention of native structure of protein during drying as measured by the spectral correlation coefficient for FTIR spectra. The plots of tau(beta) as a function of fraction of sucrose passed through a maximum at 1:1 weight ratio of sucrose to protein. That is, the molecular mobility did not correlate with the stability of protein at high levels of sucrose content. Although the glass transition appears to be an important parameter for stability, protein stabilization by sugars in the solid state cannot be wholly explained by the glass dynamics mechanism, at least as measured by tau(beta). However, it is possible that the beta-relaxations rather than the alpha-relaxations (i.e., the tau we measured) are critical to stability. The data show that storage stability correlates best with "structure" as determined by FTIR spectroscopy. However, while a specific interaction between stabilizer and protein might be responsible for the preservation of native structure, the evidence supporting this position is not compelling.

Purpose To investigate the effect of plasticizers on the stability of protein formulations in the solid state and to apply these results to a study of mechanisms of protein stabilization by sugars in the solid sate. Methods The IgG1 antibody was formulated with either sucrose or trehalose alone or a mixture of sorbitol with sucrose or trehalose. After lyophilization, the pure protein and sucrose formulations were equilibrated at different relative humidities giving residual moistures from less than 1% to 5% for sucrose systems and up to 17% for pure protein systems. All the samples were stored at 50°C for up to1 month and at 40 and 25°C for up to 6 months. Aggregation and chemical degradation were monitored by size exclusion chromatography (SEC) and ion exchange chromatography (IEX), respectively. The secondary structure was characterized by FTIR using second derivative analysis of Amide I region. Structural relaxation times, τ, an indication of molecular mobility in the glassy matrix, were characterized using the thermal activity monitor (TAM). The τ values of the recombinant human monoclonal antibody (rhuMab) formulation with various water contents were also measured in this study and compared with stability data taken from the literature (Breen ED, Curley JG, Overcashier DE, Hsu CC, Shire SJ, 2001, Pharm Res 18:1345–1353). Results The structural relaxation time, τ, decreased sharply with increasing water content. However, the stability data suggest a minimum in degradation rate at 2%–3% water content. Addition of a small amount of sorbitol to a sucrose-based formulation resulted in greater retention of native structure, smaller relaxation time, but improved stability. However, with the trehalose-based formulations, addition of sorbitol had no effect on protein structure (FTIR), but the decrease in relaxation time and the improvement in stability were qualitatively similar to the corresponding data obtained with the sucrose-based formulation. Conclusion Glass dynamics as measured by τ could not explain the stability results. Stability correlated best with the preservation of native structure for sucrose-based formulations, but with the trehalose-based formulation, neither structural relaxation time nor extent of native structure was predictive of stability. However, it is possible that the β-relaxations rather than the α-relaxation (i.e., the τ we measured) is critical to the stability. Plasticizers like glycerol may decrease τ for “α-motion” but increase τ for “β-motion” and stabilize proteins (Cicerone MT, Tellington A, Trost L, Sokolov A, 2003, BioProcess Inter 1:1–9). © 2005 Wiley-Liss, Inc. and the American Pharmacists Association
