Use of a Humanoid Robot in Supporting Dementia Care: A Qualitative Analysis.

Introduction: Cognitive impairment significantly affects independence in persons with dementia, and consistent supervision is often needed. While interest has arisen in using humanoid robots, such as Pepper, to assist with daily caregiving activities, little is known about the perceptions of using Pepper to assist people with dementia. Objective: This study aimed to explore the perceptions of nonhealthcare workers, care partners, and healthcare workers on the use of a Pepper robot in dementia care. Methods: This was a secondary qualitative analysis. Data were collected from a pilot study conducted from November 2020 to March 2021 using an online survey. The survey consisted of quantitative and qualitative questions; this study only focused on the qualitative responses. The detailed procedures and the quantitative results were published elsewhere. Participants included nonhealthcare workers, care partners, and healthcare workers. Results: A total of 194 participants responded to the open-ended question. Participants described potential benefits of Pepper including assisting with daily activities, monitoring safety and medication use, initiating reminders, and promoting activities and social interactions. Participants had concerns about privacy, cost, poor acceptance/trust, Pepper making mistakes, limitations in environmental navigation and responding to emergencies, misuse of Pepper, and Pepper replacing humans. Participants suggested that Pepper should be tailored to each individual's background, preferences, and functions and recommended improving the logistics of using Pepper, offering more emotional support and responses, and using a more natural appearance and voice. Conclusion: Pepper may support dementia care; yet some concerns need to be addressed. Future research should consider incorporating these comments when designing robots for dementia care.

A Systematic Review of Barriers and Facilitators of Pain Management in Persons with Dementia.

Approximately 50% of persons living with dementia experience pain, yet it is frequently undetected and inadequately managed resulting in adverse consequences. This review aims to synthesize evidence on the barriers and facilitators of pain management in persons living with dementia. PubMed, CINAHL, PsycINFO, and Web of Science datasets were used for article searching. Inclusion criteria were peer-reviewed original articles written in English that examined the barriers and facilitators of pain management for persons living with dementia. The Mixed Methods Appraisal Tool was used to evaluate the quality of the studies. A total of 26 studies were selected, including 18 qualitative and 3 quantitative (all high quality), as well as 5 mixed methods studies (low-to-high quality). Results were categorized into intrapersonal, interpersonal, environmental, and policy categories. Factors that impact pain management in dementia include cognitive and functional impairment, healthcare workers' knowledge, collaboration and communication, healthcare workers' understanding of patients' baseline behaviors, observation of behaviors, pain assessment tool use, pain management consistency, staffing level, pain guideline/policy, and training. Overall, pain management is challenging in persons living with dementia. The results indicate that there is a need for multi-component interventions that involves multidisciplinary teams to improve pain management in persons living with dementia at the intrapersonal, interpersonal, environmental, and policy levels. PERSPECTIVE: This review systematically synthesized barriers and facilitators of providing pain management in persons living with dementia. Results were presented in intrapersonal, interpersonal, environmental, and policy categories and suggests that multicomponent interventions involving multidisciplinary teams are needed to systematically improve pain management in persons living with dementia.

Prevalence and health outcomes in community-dwelling older adults with comorbid cancer and dementia: a longitudinal analysis.

OBJECTIVES: To examine health outcomes in community-dwelling older adults with: dementia only, cancer only, and comorbid cancer and dementia. METHODS: Longitudinal analysis was conducted using data from 2010 to 2016 waves of the Health and Retirement Study. Health outcomes included mortality, limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), nursing home utilization, hospital stay, homecare use, self-rated health, and out-of-pocket medical expenditure. Panel regression was used for statistical analysis. RESULTS: The prevalence of comorbid cancer and dementia ranged from 2.56% to 2.97%. Individuals with comorbid cancer and dementia demonstrated a higher likelihood of nursing home utilization and poorer self-rated health but a lower likelihood of hospital stay, homecare use, and out-of-pocket expenditures, compared to the cancer only or dementia only groups. The differences in mortality and ADL and IADL limitations were not statistically significant. CONCLUSION: Comorbid cancer and dementia predicted longer nursing home utilization and poorer self-rated health. The results help guide care planning for individuals with comorbid cancer and dementia.

Effect of Ambient Bright Light on Behavioral and Psychological Symptoms in People With Dementia: A Systematic Review.

Background and Objectives: Behavioral and psychological symptoms of dementia (BPSD) commonly occur in persons living with dementia. Bright light (BL) interventions have shown some positive impact on BPSD. Ambient lighting is a more efficient approach to delivering BL with better compliance and less staff workload than individual-based lighting interventions. Yet, its effect has not been systematically reviewed. This review synthesized research evidence on the effect of ambient BL on BPSD. Research Design and Methods: This review searched literature from PubMed (Medline), CINAHL, Scopus, Web of Science, and Cochrane in February 2021. Original research testing the effect of ambient BL on BPSD in persons with dementia was included. Two reviewers independently screened, extracted data, and assessed the quality of each article. Results: Nine studies were reviewed with 1 randomized controlled trial and 8 quasi-experimental studies. The sample size ranged from 14 to 89 participants across care settings. While not all studies showed positive results, evidence from multiple studies revealed the positive effect of ambient BL on depressive symptoms and agitation in persons with dementia. The ambient BL that showed a positive effect targeted at approximately 350-750 lux, 4,500-9,325 K, and/or circadian stimulus = 0.375-0.4 for 10-12 hr a day for 4 weeks or longer. Evidence on other BPSD was mixed or too limited to draw conclusions. Discussion and Implications: A preponderance of evidence suggests that, when properly designed and implemented, ambient BL shows promise in reducing depressive symptoms and agitation. Future research, using more rigorous designs, is needed to further test the effect of ambient BL on BPSD with attention to lighting parameters, measurement approaches, and intervention fidelity.

Non-pharmacological interventions for pain in people with dementia: A systematic review.

CONTEXT: Pain commonly occurs in people living with dementia but is often undertreated. Non-pharmacological interventions are a safer first-line option for pain management, but evidence-based interventions for people living with dementia have not been established. An increasing number of studies have examined the effect of non-pharmacological interventions in pain management. However, the evidence that specifically focuses on people living with dementia has not been systematically reviewed. OBJECTIVES: This review aimed to systematically synthesize current evidence on non-pharmacological interventions to manage pain in people living with dementia. METHODS: A comprehensive search of the literature was conducted in PubMed, CINAHL, Scopus, and Web of Science databases. Studies were included if they were 1) peer-reviewed original quantitative research, 2) tested the effect of non-pharmacological interventions on pain in people with dementia, and 3) English language. Studies were excluded if they 1) included both pharmacological and non-pharmacological interventions and did not report separate results for the non-pharmacological interventions; 2) enrolled participants with and without dementia and did not have separate results reported for individuals with dementia; 3) tested dietary supplements as the intervention; and 4) were not original research, such as reviews, editorials, commentaries, or case studies. Title, abstract, and full text were screened. Quality assessment was conducted using the Cochrane Risk of Bias tool and Johns Hopkins Level of Evidence. Pain assessment tools, participant characteristics, study designs, intervention condition, and results were extracted. Results were synthesized through grouping the type of the interventions and weighting evidence based on quality and design of the studies. RESULTS: A total of 11 articles and 12 interventions were identified. A total of 486 participants were included. Interventions that have shown a positive impact on pain include ear acupressure, music therapy, reflexology, tailored pain intervention, painting and singing, personal assistive robot, cognitive-behavioral therapy, play activity, and person-centered environment program. Nevertheless, a majority of the interventions were only evaluated once. Moreover, most studies had similar sample characteristics and setting. CONCLUSION: Overall, the quality of included studies were mostly low to mixed quality and most participants only had mild to moderate baseline pain, which limits detection of the intervention's effect. Hence, these findings need to be duplicated in studies with a greater sample size, a more diverse population (race, gender, and settings), and a more rigorous design to validate the results.
