The role of trust and habit in the adoption of mHealth by older adults in Hong Kong: a healthcare technology service acceptance (HTSA) model.

BACKGROUND: Evidence from the literature suggests that mobile health (mHealth) services can potentially improve healthcare outcomes among older adults. Hence, the government of Hong Kong has recently taken several community and information technology (IT) services initiatives to train older adults on how to enhance their abilities and interest in using mHealth technology. Although mHealth services have been widely implemented globally, their adoption and use by older adults are very low, including those in Hong Kong. This study aims to understand key factors influencing mHealth use intention among the older Chinese population in Hong Kong. METHODS: We extended the Unified Theory of Acceptance and Use of Technology (UTAUT2) as the basis of our conceptual framework. We applied Partial Least Squares path modeling method to conduct the Structural Equation Model (SEM) technique that allows measuring the theoretical validity of any conceptual framework. Convenience and snowball sampling methods were used to recruit participants aged 65 or above. In total, 201 valid responses were used for testing the theoretical validity of the proposed conceptual framework. RESULTS: The primary finding shows that the widely used UTAUT2 model falls short in explaining mHealth service acceptance behavior in the Chinese older population in Hong Kong. We further propose a simplified model, the Healthcare Technology Service Acceptance (HTSA) model, to understand the formation of mHealth service acceptance behavior. The findings show that trust is an important component of technology service acceptance intention behavior that was missing in the UTAUT2 model. The results also show that several antecedent factors (i.e., social influence, government policy, and service quality) are critical in forming technology trust beliefs. CONCLUSIONS: The study shows that the HTSA model can better explain mHealth acceptance behavior than the UTAUT2 model. This study advances knowledge in the mHealth technology adoption domain by proposing a simplified new version of the UTAUT2 model for understanding healthcare technology service acceptance and use intention among older adults. The findings of the study provide valuable information to the Hong Kong government and healthcare organizations for wider adoption of mHealth services, especially in older adults.

Dietary behaviour change intervention for managing sarcopenic obesity among community-dwelling older people: a pilot randomised controlled trial.

BACKGROUND: The effects of dietary intervention in managing sarcopenic obesity are controversial, and behavior change techniques are lacking in previous studies which are important for the success of dietary intervention. This study aimed to evaluate the feasibility and preliminary effects of a dietary behaviour change (DBC) intervention on managing sarcopenic obesity among community-dwelling older people in the community. METHODS: A two-armed, RCT was conducted. Sixty community-dwelling older adults (≥ 60 years old) with sarcopenic obesity were randomised into either the experimental group (n = 30), receiving a 15-week dietary intervention combined with behaviour change techniques guided by the Health Action Process Approach model, or the control group (n = 30), receiving regular health talks. Individual semi-structured interviews were conducted with 21 experimental group participants to determine the barriers and facilitators of dietary behaviour changes after the intervention. RESULTS: The feasibility of the DBC intervention was confirmed by an acceptable recruitment rate (57.14%) and a good retention rate (83.33%). Compared with the control group, the experimental group significantly reduced their body weight (p = 0.027, d = 1.22) and improved their dietary quality (p < 0.001, d = 1.31). A positive improvement in handgrip strength (from 15.37 ± 1.08 kg to 18.21 ± 1.68 kg), waist circumference (from 99.28 ± 1.32 cm to 98.42 ± 1.39 cm), and gait speed (from 0.91 ± 0.02 m/s to 0.99 ± 0.03 m/s) was observed only in the experimental group. However, the skeletal muscle mass index in the experimental group decreased. The interview indicated that behaviour change techniques enhanced the partcipants' compliance with their dietary regimen, while cultural contextual factors (e.g., family dining style) led to some barriers. CONCLUSION: The DBC intervention could reduce body weight, and has positive trends in managing handgrip strength, gait speed, and waist circumference. Interestingly, the subtle difference between the two groups in the change of muscle mass index warrants futures investigation. This study demonstrated the potential for employing dietary behaviour change interventions in community healthcare.

The Effects of Immersive Virtual Reality Applications on Enhancing the Learning Outcomes of Undergraduate Health Care Students: Systematic Review With Meta-synthesis.

BACKGROUND: Immersive virtual reality (IVR) applications are gaining popularity in health care education. They provide an uninterrupted, scaled environment capable of simulating the full magnitude of sensory stimuli present in busy health care settings and increase students' competence and confidence by providing them with accessible and repeatable learning opportunities in a fail-safe environment. OBJECTIVE: This systematic review aimed to evaluate the effects of IVR teaching on the learning outcomes and experiences of undergraduate health care students compared with other teaching methods. METHODS: MEDLINE, Embase, PubMed, and Scopus were searched (last search on May 2022) for randomized controlled trials (RCTs) or quasi-experimental studies published in English between January 2000 and March 2022. The inclusion criteria were studies involving undergraduate students majoring in health care, IVR teaching, and evaluations of students' learning outcomes and experiences. The methodological validity of the studies was examined using the Joanna Briggs Institute standard critical appraisal instruments for RCTs or quasi-experimental studies. The findings were synthesized without a meta-analysis using vote counting as the synthesis metric. A binomial test with P<.05 was used to test for statistical significance using SPSS (version 28; IBM Corp). The overall quality of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation tool. RESULTS: A total of 17 articles from 16 studies totaling 1787 participants conducted between 2007 and 2021 were included. The undergraduate students in the studies majored in medicine, nursing, rehabilitation, pharmacy, biomedicine, radiography, audiology, or stomatology. The IVR teaching domains included procedural training (13/16, 81%), anatomical knowledge (2/16, 12%), and orientation to the operating room setting (1/16, 6%). The quality of the 75% (12/16) of RCT studies was poor, with unclear descriptions of randomization, allocation concealment, and outcome assessor blinding procedures. The overall risk of bias was relatively low in the 25% (4/16) of quasi-experimental studies. A vote count showed that 60% (9/15; 95% CI 16.3%-67.7%; P=.61) of the studies identified similar learning outcomes between IVR teaching and other teaching approaches regardless of teaching domains. The vote count showed that 62% (8/13) of the studies favored using IVR as a teaching medium. The results of the binomial test (95% CI 34.9%-90%; P=.59) did not show a statistically significant difference. Low-level evidence was identified based on the Grading of Recommendations Assessment, Development, and Evaluation tool. CONCLUSIONS: This review found that undergraduate students had positive learning outcomes and experiences after engaging with IVR teaching, although the effects may be similar to those of other forms of virtual reality or conventional teaching methods. Given the identification of risk of bias and low level of the overall evidence, more studies with a larger sample size and robust study design are required to evaluate the effects of IVR teaching.

Groningen Frailty Indicator-Chinese (GFI-C) for pre-frailty and frailty assessment among older people living in communities: psychometric properties and diagnostic accuracy.

BACKGROUND: The early identification of pre-frailty and frailty among older people is a global priority because of the increasing incidence of frailty and associated adverse health outcomes. This study aimed to validate the Groningen Frailty Indicator-Chinese (GFI-C), a widely used screening instrument, and determine the optimal cut-off value in Chinese communities to facilitate pre-frailty and frailty screening. METHODS: This methodological study employed a cross-sectional and correlational design to examine the psychometric properties of GFI-C, namely, internal consistency, stability, and concurrent and construct validities. The appropriate cut-off values for pre-frailty and frailty screening in the receiver-operating characteristic (ROC) curve were determined through sensitivity and specificity analysis. RESULTS: A total of 350 community older people had been assessed and interviewed by a nurse. The GFI-C showed satisfactory internal consistency (Cronbach's α = 0.87) and two-week test-retest reliability (intra-class correlation coefficient = 0.87). Concurrent validity (r = 0.76, p < 0.001) showed a moderate correlation with Fried's frailty phenotype. The known-groups method, hypothesis testing and confirmatory factory analysis (three-factor model; χ2/df = 2.87, TLI = 0.92, CFI = 0.93, GFI = 0.92, RMR = 0.014; RMSEA = 0.073) were suitable for the establishment of construct validity. Based on the ROC and Youden's index, the optimal cut-off GFI-C values were 2 (sensitivity, 71.5%; specificity, 84.7%) for pre-frailty and 3 for frailty (sensitivity, 88.2%; specificity, 79.6%). CONCLUSIONS: The result indicated that GFI-C is a reliable and valid instrument for pre-frailty and frailty screening among older Chinese people in communities. For optimal diagnostic accuracy, the cut-off values of 3 for frailty and 2 for pre-frailty are recommended.

Sarcopenia and its association with objectively measured life-space mobility and moderate-to-vigorous physical activity in the oldest-old amid the COVID-19 pandemic when a physical distancing policy is in force.

INTRODUCTION: The oldest-old are highly vulnerable to sarcopenia. Physical distancing remains a common and effective infection-control policy to minimize the risk of COVID-19 transmission during the pandemic. Sarcopenia is known to be associated with impaired immunity. Moderate-to-vigorous physical activity (MVPA) and life-space mobility (LSM) are potential strategies for minimizing the risk of sarcopenia. However, a physical distancing policy might jeopardize the practice of MVPA and LSM. The purposes of this study were to identify the prevalence of sarcopenia and examine the association between MVPA and LSM with sarcopenia in the community-dwelling oldest-old during the COVID-19 pandemic. METHODS: This study employed a cross-sectional and observational design. The study was conducted in 10 community centres for older people in Hong Kong during the period of the COVID-19 pandemic (September to December 2020). Eligible participants were the oldest-old people aged ≥85 years, who were community-dwelling and had no overt symptoms of cognitive impairment or depression. Key variables included sarcopenia as measured by SARC-F, LSM as measured by a GPS built into smartphones, and MVPA as measured by a wrist-worn ActiGraph GT3X+. Variables were described by mean and frequency. A multiple linear regression was employed to test the hypotheses. The dependent variable was sarcopenia and the independent variables included LSM and MVPA. RESULTS: This study recruited 151 eligible participants. Their mean age was 89.8 years and the majority of them were female (n = 93/151, 61.6%). The prevalence of sarcopenia was 24.5% (n = 37/151) with a margin of error of 6.86%. MVPA was negatively associated with sarcopenia in older people (ß = - 0.002, SE = 0.001, p = 0.029). However, LSM was not associated with sarcopenia. CONCLUSION: The prevalence of sarcopenia in the community-dwelling oldest-old population is high. MVPA is negatively associated with sarcopenia. LSM is unrelated to sarcopenia. Sarcopenia should be recognized and the oldest-old with sarcopenia should be accorded priority treatment during the COVID-19 pandemic.

Gathering policymakers' perspectives as an essential step in planning and implementing palliative care services at a national level: an example from a resource-limited country.

BACKGROUND: Despite increasing recognition of the role played by palliative care (PC) services, the priorities of policymakers in supporting PC remain unclear and have sometimes engendered controversy. There are few studies exploring policymakers' perspectives towards PC services, with most shedding light on obstacles to PC development. Furthermore, no study has explored policymakers' perspectives towards providing PC at the national level in resource-limited countries. This study provides a platform for providing PC as part of the Palestinian healthcare system (HCS) by exploring policymakers' perspectives on PC, an essential step to developing a PC programme. METHODS: A descriptive qualitative study design was employed using semi-structured interviews. Participants were those identified as responsible for making executive and legislative decisions about health services (including PC) in the HCS. Data were analysed using qualitative content analysis. RESULTS: Twelve decision and policymakers participated in the study. Four categories were generated from the content analysis: (1) the nature of current PC healthcare services, (2) the potential benefits of PC, (3) challenges to providing PC, and (4) considerations in providing PC. The current PC services provided to Palestinian patients with life-limiting illnesses and their families are not comprehensive, and are limited to symptom management. There is a Palestinian national strategic plan for developing PC; however, the development goals are not clearly defined, and the plan's capabilities are inadequate. Several challenges to the provision of PC were found to relate to issues of education and training, the allocation of funding, and the availability of medications. CONCLUSIONS: Integrating PC into the Palestinian university curricula as a compulsory course and establishing higher degree programmes in PC to overcome the shortage of PC specialists is required. Developing policies aligned with national laws could help enhance health services to patients and their families and resolve several challenges. Cooperating with national and international institutions in seeking funding could boost PC development and medication availability.

A simplified 10-step Tai-chi programme to enable people with dementia to improve their motor performance: a feasibility study.

OBJECTIVE:: To evaluate the feasibility and preliminary effects of a simplified 10-step Tai-chi programme to improve the motor performance of people with dementia. DESIGN:: A two-arm, single-blinded cluster randomized controlled trial, registered with ClinicalTrials.gov (NCT03341091). SETTING:: Community health centres. PARTICIPANTS:: Twenty-six dyads of people with dementia and their family caregivers were recruited, with mean (SD) ages of 82.2 (7.43) and 51.3 (18.97), respectively. INTERVENTIONS:: The experimental group underwent a 16 week 10-step simplified Tai-chi training programme, with additional measures to enhance engagement. The control group joined recreational activities organized by the centres. MAIN OUTCOME MEASURE(S):: The feasibility assessment included recruitment, attrition, adherence to, and engagement in the Tai-chi programme. The preliminary effects were assessed by the participants' performance in mobility tests. RESULTS:: Preliminary feasibility was established, with an acceptable recruitment rate of 58% (26 out of 45 assessed dyads) and a high attendance rate of 81% (25.88 out of 32 Tai-chi sessions). There was positive engagement in the training sessions, and no adverse incidents. However, five participants withdrew from the Tai-chi group, for a high attrition rate of 38%, and the mean home practice time decreased between weeks 8 and 16. In most of the motor performance tests, a slight but insignificant improvement was observed in the Tai-chi group compared to the control group. CONCLUSION:: A tailored Tai-chi programme for people with dementia using a dyadic approach has been found to be feasible. However, stronger support must be provided to family caregivers to improve the participants' sustained participation.

Knowledge, Practice, and Attitude of Nursing Home Staff Toward the Use of Physical Restraint: Have They Changed Over Time?

PURPOSE: Use of physical restraints is common in nursing homes, although empirical evidence has shown it to be a hazardous measure. This article aims to understand whether there were any changes in nursing home staff's knowledge, attitudes, and practices of using physical restraints in Hong Kong, after years of deliberation on this topic. METHODS: A questionnaire about the knowledge, attitude, and practice of using physical restraint was sent to all 298 staff members in four nursing homes in Hong Kong run by a nongovernmental organization. The results were compared with previous findings from 1999 using the same questionnaire. RESULTS: Overall, the staff had satisfactory knowledge of the daily application of physical restraints, such as the operational procedure and daily assessment. Concerning the conceptual knowledge of minimizing physical restraint use, their performance in the survey was less satisfactory. For example, only 6.6% of respondents were aware that residents had a right to reject the use of physical restraints, and 70% believed that there were no good alternatives to restraints. They showed appropriate attitudes in their practice of daily use of physical restraints. Compared with the previous study in 1999, a significant improvement was found in the attitudes (p = .0014) and practice (p = .0002) of using restraints, but there was no difference in their knowledge test results (p = .29). CONCLUSIONS: The results of this study show a significant improvement among the nursing home staff in terms of their attitudes and practice of using restraints. In-service training for nursing staff should focus more on their knowledge of ethical considerations and the hands-on practice of using alternative devices (e.g., motion detectors or anti-slip pads). CLINICAL RELEVANCE: The findings of this study suggest that in-service training for nursing staff should focus more on their knowledge of ethical considerations, the principles of using physical restraint, and the alternatives to restraint in order to fill the knowledge gaps of staff and improve the quality of care in nursing homes.

Pain Treatments for Nursing Home Residents with Advanced Dementia and Substantial Impaired Communication: A Cross-Sectional Analysis at Baseline of a Cluster Randomized Controlled Trial.

OBJECTIVES: This is a cross-sectional analysis at baseline of a cluster randomized controlled trial to identify factors associated with the use of pharmacological and nonpharmacological pain treatments by nursing home residents with dementia and impaired communication. METHODS: One hundred thirty-four residents with dementia and impaired communication were recruited. Nine of them were excluded because data on their pain treatments were missing, resulting in 125 for analysis. Hierarchical generalized estimating equations analyses controlling for the clustering effect of nursing homes were used to identify factors associated with the use of pharmacological and nonpharmacological pain treatments. RESULTS: Although all participants had a confirmed pain condition, only 23 (18.4%) and 45 (36%) had received pharmacological or nonpharmacological pain treatments, respectively. Participants with a higher ability to communicate ( P = 0.031) and fewer pain locations were found to be more likely to receive pain medications, with the impact of communication ability being greater among participants with better cognitive status than among those with poor cognitive status. Participants who had been living in the home longer and who were more dependent were less likely to receive nonpharmacological treatments. CONCLUSION: Suboptimal pain management was common among this population. Severe impairment in the ability to communicate is a major reason for the underuse of pain medications. Staff may become desensitized and fail to perceive subtle changes in the residents' behavior as indicative of pain, leading to the underadministering of nonpharmacological treatments. To improve this situation, it is suggested that observational pain assessments be systematically carried out in nursing homes.

The severity and associated factors of participation restriction among community-dwelling frail older people: an application of the International Classification of Functioning, Disability and Health (WHO-ICF).

BACKGROUND: The International Classification of Functioning, Disability, and Health (WHO-ICF) describes participation restriction as one aspect of disability. Participation restriction refers to health problems that can hinder people's involvement in different life events. It is rational to believe that the prevalence of participation restriction increases among a frail population. However, information about the level of participation restriction among older people, particularly the pre-frail or frail, remains scant. The aim of this study was to identify the prevalence and underlying risk factors associated with participation restriction among community-dwelling frail and pre-frail older people. METHODS: A cross-section of 299 community-dwelling frail older people with a mean age of 79.5 participated in this study. They had to have been identified as being either pre-frail or frail based on the five common characteristics of the frailty phenotype. Their level of participation restriction was assessed based on the Chinese Reintegration to Nursing Living Index (C-RNLI). All other independent variables were identified and systematically linked to different components in the WHO-ICF framework. RESULTS: Among all participants, 207 (69.2%) were identified as encountering participation restrictions in at least one aspect of their life, with a mean C-RNLI score of 68.3 (SD 19.43). A multivariate regression analysis showed that the participants' status of frailty, self-perceived social status, level of exhibited depressive mood, sleep quality, mobility, level of fear of falling, and physical activity levels had a significant association with participation restriction. When all of the variables, regardless of significance, were included, the factors together explained 67.1% of the variance in the participants' participation restriction. CONCLUSION: Participation restriction was prevalent among community-dwelling frail older people and was associated with factors across different components in the WHO-ICF. This finding supports the view that participation restriction is multifactorial in nature.

The psychometric properties of the Chinese version-reintegration to normal living index (C-RNLI) for identifying participation restriction among community-dwelling frail older people.

BACKGROUND: The Reintegration to Normal Living Index (RNLI) was developed to measure reintegration to normal living after major traumas/illnesses. Its psychometric properties remain unknown when used to measure participation restriction under the World Health Organization's International Classification of Functioning, Disability, and Health (WHO-ICF) framework. This study examines the psychometric properties of the Chinese version-RNLI to measure WHO-ICF participation restriction among community-dwelling pre-frail and frail older people. METHODS: A cross-sectional study was conducted in community and day-care centres in Hong Kong between May 2015 and January 2016. Through face-to-face interviews, information was collected on the participants' demographic background, medical history, frailty status, depressive mood, functional performance in daily activities, and participation restriction. The internal consistency, test-retest reliability, and construct and convergent validity of the C-RNLI were assessed. RESULTS: Two hundred and ninety-nine pre-frail or frail community-dwelling older people with a mean age of 79.53 were recruited. A confirmatory factor analysis showed that the C-RNLI has a two-factor structure comprised of "participation in physical activities" and "participation in social events". The test-retest coefficient was 0.71. The Cronbach's alpha of the total C-RNLI score, and those of the factors "participation in physical activities" and "participation in social events" were 0.88, 0.82 and 0.84, respectively. Pre-frail older people had significantly higher scores for the factors "participation in physical activities" (z = -5.05, <0.01) and "participation in social events" (z = -6.04, p < 0.01) than frail older people. Older people from community centres had significantly higher scores for the factors "participation in physical activities" (z = -4.48, <0.01) and "participation in social events" (z = -4.03, p < 0.01) than older people from day-care centres. The factors "participation in physical activities" and "participation in social events" of the C-RNLI were significantly convergent with depressive mood (rs = -0.25 and rs = -0.39, respectively) and functional performance in daily activities (rs = 0.28 and rs = 0.45, respectively). CONCLUSIONS: The C-RNLI is a two-factor structured scale with acceptable level of reliability and validity to measure WHO-ICF participation restriction among community-dwelling pre-frail and frail older people.

How the perspectives of nursing assistants and frail elderly residents on their daily interaction in nursing homes affect their interaction: a qualitative study.

BACKGROUND: Good support from and positive relations with institutional staff can enhance the psychosocial wellbeing of residents admitted to a nursing home. Nursing assistants (NAs) interact most frequently with residents and play an important role in developing good rapport with them. Most studies have described the daily interactions between NAs and residents as task oriented. Only few have attempted to explore the perspectives of NAs and residents on their daily interactions. Therefore, the aim of this study was to identify the types of daily interactions perceived by NAs and residents. We also investigated those intentions/beliefs held by NAs and residents that might direct their interactive behaviors. METHODS: A descriptive, exploratory, qualitative approach was used to explore the perspectives of 18 NAs (mean age: 51) and 15 residents (mean age: 84.4) on their daily interactions. Unstructured in-depth interviews were used to collect data. All of the interviews were conducted from July to December 2013. The collected data were transcribed verbatim and analyzed by content analysis. RESULTS: Three types of interactions were found that described the NAs' and residents' perspectives on their daily interactions: (1) physiologically-oriented daily interactions; (2) cordial interactions intended to maintain a harmonious atmosphere; and (3) reciprocal social interactions intended to develop closer rapport. One or more themes reflecting the participants' intentions or beliefs were identified from each group to support each type of interaction. CONCLUSIONS: An over-emphasis on the formal caring relationship and over-concern about maintaining a harmonious atmosphere contributed to a superficial and distant relationship between the two parties. Building close rapport takes time and involves repeated reciprocal social interactions. The findings showed that with good intentions to establish closer rapport, both NAs and residents did favors for each other. All of those favors were easily integrated in the care provided to the residents without increasing the workload of the NAs. Modifying the training given to NAs and adjusting institutional policies are crucial to raising the competence of the NAs in building good relationships with residents. Positive interactions improve the psychosocial wellbeing of the residents and encourage them to cooperate during the delivery of care, thereby improving their overall health and contributing to the NAs' job satisfaction.

Feasibility and preliminary effects of a mindfulness-based physical exercise (MBPE) program for community-dwelling older people with sarcopenia: A protocol for a parallel, two-armed pilot randomised controlled trial.

INTRODUCTION: Physical exercise (PE) is essential for alleviating the symptoms of sarcopenia. Low motivation is a major barrier to PE. Mindfulness-based intervention (MBI) has the potential to improve motivation. However, few studies have used a mindfulness-based PE (MBPE) intervention among older people with sarcopenia. OBJECTIVES: To assess the feasibility, acceptability and preliminary effects of the MBPE program among community-dwelling older people with sarcopenia. METHODS AND ANALYSIS: A two-arm pilot randomised controlled trial will be conducted to assess the feasibility, acceptability and preliminary effects of an MBPE program among community-dwelling older people with sarcopenia. A total of 60 participants will be randomised into the intervention group, receiving the MBPE intervention twice a week over 12 weeks, or the control group, receiving health education with the same duration, number of sessions and frequency as the intervention group. Each session of the MBPE program will last about 60 min, including 5-10- min introduction, 20-min MBI, 30-min PE and 5-10-min sharing and discussion. The primary outcomes will be the feasibility (i.e., the time spent recruiting participants, the eligibility rate and the recruitment rate) and acceptability (i.e., the attendance rate, completion rate and attrition rate) of the MBPE program. The secondary outcomes will be the preliminary effects of the MBPE program on symptoms of sarcopenia, motivation for PE, psychological well-being, mindfulness level, physical activity level and quality of life. Individual interviews will be conducted to identify the strengths, limitations and therapeutic components of the intervention. The quantitative data will be analysed by generalised estimating equations. The qualitative data will be analysed by Braun and Clarke's thematic approach. CONCLUSION: The findings of this study will be able to provide evidence for the health professionals in adopting MBPE as a supportive intervention for the older adults with sarcopenia and the groundworks for the researchers in developing non-pharmacological intervention for older adults. The positive effects could facilitate healthy ageing and relief the burden of the medical system, especially in the countries facing the ageing population.

Reproducibility and Relative Validity of a Short Food Frequency Questionnaire for Chinese Older Adults in Hong Kong.

Changes in an individual's digestive system, hormones, senses of smell and taste, and energy requirement accompanying aging could lead to impaired appetite, but older adults may not notice their risk of nutrient deficiency. When assessing the dietary intake of older adults, it was found that they had more difficulties with short-term recall and open-ended recall and would experience greater fatigue and frustration when compared to younger individuals when completing a lengthy questionnaire. There is a need to develop a brief dietary assessment tool to examine the nutritional needs of older adults. In this study, we aimed to assess the diet of Hong Kong older adults using the short FFQ and examine its reproducibility and relative validity as a dietary assessment tool. Dietary data of 198 older adults were collected via FFQs and three-day dietary records. Correlation analyses, cross-tabulation, one-sample t-tests, and linear regression analyses were used to evaluate the relative validity of the short FFQ. In general, the short FFQ was accurate in assessing the intake of phosphorus, water, grains, and wine, as shown by a significant correlation (>0.7) between values reported in the FFQs and dietary records; good agreement (more than 50% of observations belonged to the same quartile) and insignificant differences detected with the one-sample t-tests and linear regression analyses were observed for the above four variables. Additionally, the intake of proteins, carbohydrates, total fat, magnesium, and eggs in terms of the values reported in the FFQs and dietary records showed good agreement.

The Effects of Immersive Virtual Reality-Assisted Experiential Learning on Enhancing Empathy in Undergraduate Health Care Students Toward Older Adults With Cognitive Impairment: Multiple-Methods Study.

BACKGROUND: Immersive virtual reality (IVR)-assisted experiential learning has the potential to foster empathy among undergraduate health care students toward older adults with cognitive impairment by facilitating a sense of embodiment. However, the extent of its effectiveness, including enhancing students' learning experiences and achieving intended learning outcomes, remains underexplored. OBJECTIVE: This study aims to evaluate the impacts of IVR-assisted experiential learning on the empathy of undergraduate health care students toward older people with cognitive impairment as the primary outcome (objective 1) and on their learning experience (objective 2) and their attainment of learning outcomes as the secondary outcomes (objective 3). METHODS: A multiple-methods design was used, which included surveys, focus groups, and a review of the students' group assignments. Survey data were summarized using descriptive statistics, whereas paired 2-tailed t tests were used to evaluate differences in empathy scores before and after the 2-hour IVR tutorial (objective 1). Focus groups were conducted to evaluate the impacts of IVR-assisted experiential learning on the empathy of undergraduate health care students toward older people with cognitive impairment (objective 1). Descriptive statistics obtained from surveys and thematic analyses of focus groups were used to explore the students' learning experiences (objective 2). Thematic analysis of group assignments was conducted to identify learning outcomes (objective 3). RESULTS: A total of 367 undergraduate nursing and occupational therapy students were recruited via convenience sampling. There was a significant increase in the students' empathy scores, measured using the Kiersma-Chen Empathy Scale, from 78.06 (SD 7.72) before to 81.17 (SD 8.93) after (P<.001). Students expressed high satisfaction with the IVR learning innovation, with a high satisfaction mean score of 20.68 (SD 2.55) and a high self-confidence mean score of 32.04 (SD 3.52) on the Student Satisfaction and Self-Confidence scale. Students exhibited a good sense of presence in the IVR learning environment, as reflected in the scores for adaptation (41.30, SD 6.03), interface quality (11.36, SD 3.70), involvement (62.00, SD 9.47), and sensory fidelity (31.47, SD 5.23) on the Presence Questionnaire version 2.0. In total, 3 major themes were identified from the focus groups, which involved 23 nursing students: enhanced sympathy toward older adults with cognitive impairment, improved engagement in IVR learning, and confidence in understanding the key concepts through the learning process. These themes supplement and align with the survey results. The analysis of the written assignments revealed that students attained the learning outcomes of understanding the challenges faced by older adults with cognitive impairment, the importance of providing person-centered care, and the need for an age-friendly society. CONCLUSIONS: IVR-assisted experiential learning enhances students' knowledge and empathy in caring for older adults with cognitive impairment. These findings suggest that IVR can be a valuable tool in professional health care education.

Virtual reality-based simulation intervention for enhancing the empathy of informal caregivers of people with dementia: A mixed-methods systematic review.

Dementia is a long-term and progressive syndrome that not only influences the person with dementia (PWD) but also the caregiver. However, informal caregivers are not always empathic and understand the symptoms of dementia, leading to destructive caregiving relationships and poor quality of caregiving. VR-based simulation interventions can provide a more realistic and memorable learning experience for caregivers to walk in PWDs' shoes. This review aimed to provide practitioners and researchers with insights on developing and/or adopting an effective VR-based simulation intervention for enhancing the empathy of informal caregivers of PWD. A mixed-methods systematic review was conducted. Quantitative, qualitative, and mixed-methods studies were searched from MEDLINE, PsycINFO, CINAHL, Scopus, Embase, and Cochrane Library updating. Standard JBI critical appraisal instruments were used for the quality appraisal. A convergent segregated approach was used to synthesize and integrate the data. A total of seven studies were included. Inconsistent quantitative results were reported on the effects of VR-based simulation on empathy enhancement. Significant effects were reported on knowledge of dementia and emotion-focused coping strategies. Two themes were generated from the qualitative studies, including "Informal caregivers gained better insight into problems encountered by older people with dementia" and "Thinking from the perspective of older people with dementia, leading to changes in attitudes and behaviours towards dementia". The qualitative synthesized evidence showed that informal caregivers gained better insight into problems encountered by PWD, but the quantitative synthesized results are inconsistent. Yet, informal caregivers experienced a change in attitude by thinking from the perspective of PWD.

An AI-empowered indoor digital contact tracing system for COVID-19 outbreaks in residential care homes.

An AI-empowered indoor digital contact-tracing system was developed using a centralized architecture and advanced low-energy Bluetooth technologies for indoor positioning, with careful preservation of privacy and data security. We analyzed the contact pattern data from two RCHs and investigated a COVID-19 outbreak in one study site. To evaluate the effectiveness of the system in containing outbreaks with minimal contacts under quarantine, a simulation study was conducted to compare the impact of different quarantine strategies on outbreak containment within RCHs. The significant difference in contact hours between weekdays and weekends was observed for some pairs of RCH residents and staff during the two-week data collection period. No significant difference between secondary cases and uninfected contacts was observed in a COVID-19 outbreak in terms of their demographics and contact patterns. Simulation results based on the collected contact data indicated that a threshold of accumulative contact hours one or two days prior to diagnosis of the index case could dramatically increase the efficiency of outbreak containment within RCHs by targeted isolation of the close contacts. This study demonstrated the feasibility and efficiency of employing an AI-empowered system in indoor digital contact tracing of outbreaks in RCHs in the post-pandemic era.

A distress thermometer with a cutoff score of ≥ 6 is the optimal point to identify highly distressed patients with advanced cancer stages in resource-limited countries without palliative care services.

Purpose: Although the distress thermometer (DT) scale has been widely validated and used in different cancer types and settings, an optimal cutoff score of DT is not defined to screen advanced cancer patients. The study aimed to define the optimal DT's cutoff score among advanced cancer patients in resource-limited countries without palliative care services and to assess the prevalence and factors associated with psychological distress among this population. Methods: A secondary analysis was performed. Three hundred seventy-nine patients were recruited from Palestine. Participants completed the DT and the Hospital Anxiety and Depression Scale (HADS). Receiver operating characteristic analysis (ROC) was used to define the optimal cutoff score for the DT against HADS-Total ≥15. Multiple logistic regression was utilized for identifying the factors associated with psychological distress of the DT. Results: A DT cutoff score ≥ 6 correctly identified 74% of HADS distress cases and 77% of HADS non-distress cases, with a positive predictive value (PPV) and negative predictive value (NPV) of 97% and 18%, respectively. The prevalence of distress was found to be 70.7%, and the major sources of distress were related to physical (n = 373; 98.4%) and emotional problems (n = 359; 94.7%). Patients with colon (OR = 0.44, 95% CI: 0.31 - 0.62) and lymphoid cancers (OR = 0.41, 95% CI: 0.26 - 0.64) were less likely to have psychological distress than patients with other types of cancer, whereas patients with lung (OR = 1.80, 95% CI: 1.20 - 2.70) and bone cancers (OR = 1.75, 95% CI: 1.14 - 2.68) were more likely to experience it. Conclusion: A cutoff DT score of 6 appeared acceptable and effective for screening distress in patients with advanced cancer stages. Palestinian patients exhibited a high level of distress, and the high prevalence supports the argument of using a DT within the standard delivery of cancer care to identify highly distressed patients. These highly distressed patients should then be involved in a psychological intervention programme.

Health maintenance through home-based interventions for community-dwelling older people with sarcopenia during and after the COVID-19 pandemic: A systematic review and meta-analysis.

BACKGROUND: The COVID-19 pandemic has greatly impacted people's lifestyles and changed the delivery of health interventions, especially interventions for community-dwelling older people with sarcopenia. OBJECTIVE: To summarize the components and explore the effectiveness of home-based interventions for improving sarcopenia and other health-related outcomes among community-dwelling older people with sarcopenia. DESIGN: Systematic review and meta-analysis. METHODS: The Cochrane Library, Scopus, EMBASE, Web of Science, CINAHL, Medline (via PubMed), and PsycINFO were searched for relevant papers published from January 1, 2010 to March 29, 2022. Only papers written in English were included. The modified version of Cochrane's risk-of-bias tool was used to assess the risks of bias in the included studies. The template for intervention description and replication checklist was used to summarize the intervention components. The mean difference (MD) or standard mean difference with a 95 % confidence interval (CI) was used to determine the effect size of studies using the same or different measuring methods. Random-effects models were in meta-analyses to pool the effects of home-based interventions on the included outcomes. RESULTS: After detailed screening and exclusion, 11 randomized controlled trials including 1136 older people with sarcopenia were included in our analyses. Three categories of home-based interventions were identified: exercise interventions, nutritional interventions, and combined exercise and nutritional interventions. The overall analysis of the outcomes (e.g., appendicular skeletal muscle mass index, lean mass, body fat mass, handgrip strength, and gait speed), showed that the effects of home-based exercise interventions were inconclusive. Compared with passive controls, home-based exercise interventions significantly improved knee extension strength (MD = 0.56 kg, 95 % CI: 0.09, 1.03, p = 0.020) and reduced the time required to complete the Timed Up and Go Test (MD = -1.41 s, 95 % CI: -2.28, -0.54, p = 0.001). Home-based nutritional interventions were effective in improving appendicular skeletal muscle mass (MD = 0.25 kg, 95 % CI: 0.02, 0.49, p = 0.030), gait speed (MD = 0.06 m/s, 95 % CI: 0.03, 0.09, p = 0.0001), and quality of life in terms of both the physical component summary (MD = 13.54, 95 % CI: 0.73, 26.34, p = 0.040) and mental component summary scores (MD = 8.69, 95 % CI: 2.98, 14.41, p = 0.003). CONCLUSION: Home-based exercise interventions have the potential to improve muscle strength and physical function, while home-based nutritional interventions are effective in increasing muscle mass, physical function, and quality of life. Both of these can be applied at home during and after the COVID-19 pandemic to alleviate sarcopenia and improve health-related outcomes in community-dwelling older people.

Long-term effects of e-Health secondary prevention on cardiovascular health: a systematic review and meta-analysis.

AIMS: Despite the well-documented short-to-medium-term effectiveness of e-Health (electronic health) secondary prevention interventions on patients with cardiovascular disease (CVD), there is limited empirical evidence regarding long-term effectiveness. This review aims to evaluate the long-term effects of e-Health secondary prevention interventions on the health outcomes of patients with CVD. METHODS AND RESULTS: This systematic review and meta-analysis followed Cochrane Handbook for Systematic Reviews of Interventions. EMBASE, Medline, Web of Science, and Scopus were searched from 1990 to May 2022. Randomized controlled trials investigating the effects of e-Health secondary prevention on health outcomes of CVD patients that collected endpoint data at ≥ 12 months were included. RevMan 5.3 was used for risk of bias assessment and meta-analysis. Ten trials with 1559 participants were included. Data pooling suggested that e-Health programmes have significantly reduced LDL cholesterol [n = 6; SMD = -0.26, 95% confidence interval (CI): (-0.38, -0.14), I2 = 17%, P < 0.001]; systolic blood pressure [n = 5; SMD = -0.46, 95% CI: (-0.84, -0.08), I2 = 90%, P = 0.02]; and re-hospitalization, reoccurrence, and mortality [risk ratio = 0.36, 95% CI: (0.17, 0.77), I2 = 0%, P = 0.009]. Effects on behavioural modification, physiological outcomes of body weight and blood glucose, and quality of life were inconclusive. CONCLUSION: e-Health secondary prevention is effective in improving long-term management of risk factors and reducing the reoccurrence of cardiac events in patients with CVD. Results are inconclusive for behaviour modification and quality of life. Exploring, implementing, and strengthening strategies in e-Health secondary prevention programmes that focus on maintaining behaviour changes and enhancing psychosocial elements should be undertaken.
