Effects of Visual Aids for End-of-Life Care on Decisional Capacity of People With Dementia

A visual approach to facilitating conversations about supportive care options in the context of cognitive impairment

BACKGROUND

Persons with cognitive impairment may experience difficulties with language and cognition that interfere with their ability to communicate about health-related decision making.

OBJECTIVE

We developed a visual elicitation technique to facilitate conversations about preferences concerning potential future supportive care needs and explored the utility of this technique in a qualitative interview study.

METHODS

We conducted 15 online interviews with persons with mild cognitive impairment and mild to moderate dementia, using storytelling and a virtual tool designed to facilitate discussion about preferences for supportive care. Interviews were transcribed verbatim and analyzed using an inductive qualitative data analysis method. We report our findings with respect to several main themes. First, we considered participants' perspectives on supportive care. Next, we examined the utility of the tool for engaging participants in conversation through two themes: cognitive and communicative processes exhibited by participants; and dialogic interactions between the interviewer and the participant.

RESULTS

With respect to participants' perspectives on supportive care, common themes included considerations relating to informal caregivers such as availability and burden, and the quality of care options such as paid caregivers. Other themes, such as the importance of making decisions as a family, considerations related to facing these challenges on one's own, and the fluid nature of decision making, also emerged. Common communicative processes included not being responsive to the question and unclear responses. Common cognitive processes included uncertainty and introspection, or self-awareness, of one's cognitive abilities. Last, we examined dialogic interactions between the participant and the interviewer to better understand engagement with the tool. The interviewer was active in using the visualization tool to facilitate the conversation, and participants engaged with the interface to varying degrees. Some participants expressed greater agency and involvement through suggesting images, elaborating on their or the interviewer's comments, and suggesting icon labels.

CONCLUSION

This article presents a visual method to engage older adults with cognitive impairment in active dialogue about complex decisions. Though designed for a research setting, the diverse communication and participant-interviewer interaction patterns observed in this study suggest that the tool might be adapted for use in clinical or community settings.

Multi-colour reflective metagrating with neutral transparency for augmented reality

This paper presents the design and experimental validation of an all-dielectric and transparent metagrating-based metalens. Leveraging multiple guided mode resonances simultaneously, the metagrating enables the generation of two or more spectrally narrow reflection peaks. These peaks are achieved through the precise engineering of guided mode resonances, allowing for the reflection of a comb of vibrant and saturated colours. In addition to the investigation of underlying mechanisms, we introduce an analytical numerical method that facilitates rapid engineering of the spectral positions of the reflection peak comb. Experimental validation is provided for a bichromatic sample. Such metagrating can be promising for augmented reality systems, supporting individuals with mild to moderate cognitive impairments by delivering visual and textual stimuli that can improve indoor navigation, home safety, communication, and decision-making.

Identifying Components of a Person-Centered Augmentative and Alternative Communication Intervention for People With Dementia: Opinions of an International Expert Panel

PURPOSE

Despite general agreement on the importance of person-centered care in speech-language pathology, guidelines for developing person-centered interventions for those with dementia are limited. This study aimed to obtain expert opinion on the components of a person-centered augmentative and alternative communication (AAC) intervention for persons with dementia.

METHOD

A modified electronic Delphi technique was employed in a single round. A purposively sampled panel of experts was invited to provide their opinion on three open-ended questions related to (a) the elements of person-centered care, (b) communication supports, and (c) the interaction outcomes of a person-centered intervention. Thirty-one experts from nine countries participated on the panel. The majority were speech-language pathologists primarily involved in research. Qualitative written data were coded and analyzed using content analysis.

RESULTS

Nine components were identified across the three open-ended questions: (a) the unique characteristics of the person with dementia, (b) working with a person with dementia, (c) preserving personhood, (d) a different view on person-centered care, (e) a range of communication supports, (f) supportive conversational partners, (g) designing communication supports, (h) interaction outcome measure, and (i) meaningful interaction outcomes.

CONCLUSION

This study identified nine components that are useful in guiding speech-language pathologists in crafting future person-centered AAC interventions for people with dementia.

Resources to Support Decision-Making Regarding End-of-Life Nutrition Care in Long-Term Care: A Scoping Review

Resources are needed to aid healthcare providers and families in making end-of-life nutrition care decisions for residents living in long-term care settings. This scoping review aimed to explore what is reported in the literature about resources to support decision-making at the end of life in long-term care. Four databases were searched for research published from 2003 to June 2023. Articles included peer-reviewed human studies published in the English language that reported resources to support decision-making about end-of-life nutrition in long-term care settings. In total, 15 articles were included. Thematic analysis of the articles generated five themes: conversations about care, evidence-based decision-making, a need for multidisciplinary perspectives, honouring residents' goals of care, and cultural considerations for adapting resources. Multidisciplinary care teams supporting residents and their families during the end of life can benefit from resources to support discussion and facilitate decision-making.

Legal issues in end-of-life care for speech-language pathologists and social workers: A scoping review

PURPOSE

End-of-life law governs end-of-life decision-making in clinical practice. There has been little analysis of the specific legal issues relevant to allied health professionals working in end-of-life care.

METHOD

A scoping review was undertaken to identify and examine the extent, range, and nature of literature on the legal issues relevant to end-of-life practice for Australian speech-language pathologists and social workers, including current gaps. Literature was identified by searching six electronic databases, Google Scholar, the websites of relevant professional organisations and State/Territory health departments, scanning reference lists, and drawing on existing knowledge. Data charting and thematic analysis of findings was performed.

RESULT

Twenty documents were included, spanning various document types. Most focused on adult clinical practice. Documents demonstrated that the two professions encounter similar legal issues.

CONCLUSION

Key gaps exist in the literature. Findings will inform these professionals of the legal issues relevant to their clinical practice and inform the development of further resources.

Communication strategies for adults in palliative care: the speech-language therapists' perspective

BACKGROUND

Communication disorders are a challenge that many patients in palliative care (PC) may encounter. This intervention area is emerging for the speech-language therapist (SLT), the professional who works in preventing, assessing, diagnosing, and treating human communication disorders. This study aims to identify and classify the communication strategies considered most important by SLTs for use in PC and evaluate whether there are any differences in perception regarding the importance of strategies between SLTs with and without PC experience.

METHODS

This cross-sectional quantitative study was conducted using a survey, which employed a well-structured, self-completion questionnaire previously validated by a panel of experts with over six years of PC experience.

RESULTS

The strategies rated as most important within each group were the following: (i) adjust the patient's position and minimise environmental noise; (ii) establish eye contact and adjust the pace of speech; (iii) adjust the language level and raise one topic at a time; (iv) use images of the patient's interests and their personal objects; (v) use orality and multimodal form; (vi) use simplified language and structured pauses; and (vii) use tables with images and books with pictures.

CONCLUSIONS

Verbal and non-verbal strategies were rated as highly important. There was no evidence of differences in perception in terms of importance between the SLTs with or without experience in PC, but more studies are needed to support this aspect. The patient's communication ability is one of the cornerstones of PC quality. Through their actions, speech-language professionals could empower the patient with strategies so that they can autonomously and self-determinedly express their experiences and most significant needs.

Communicating Risks and Food Procedures through a Visual Poster for Caregivers of Patients with Dysphagia in Inpatient Care: Usability and Impact

Food-related procedures are a part of rehabilitation interventions for dysphagia. However, studies show that professional-caregiver communication is often lacking in dysphagia, risking caregivers' knowledge, understanding, and practice of those procedures, with negative consequences for patient safety and rehabilitation. The aim of this study was to evaluate caregivers' perspectives about the utility of a poster designed to communicate dysphagia-related risks and food procedures for caregivers of patients in inpatient care. The impact of caregivers' exposure to the poster on patients' dysphagia-related health was additionally explored. The poster was placed by the beds of a randomly assigned group of patients (n = 21). Their caregivers responded to a questionnaire about the poster's utility. In addition, to explore whether the caregiver exposure to the poster could already have some effect on patient dysphagia-related health, patient risk of aspiration, food swallowing capacity, nutritional status, and oral cavity health were assessed before and one month after placement of the poster, and the poster-exposed group was compared with a (randomly-assigned) non-exposed group (n = 21). Data were analyzed with descriptive statistics and generalized linear models based on analyses of covariance. All caregivers across various education levels reported noticing, reading, and understanding the poster (100%). Nearly all reported that the poster added new information to their knowledge (17 out of 21). In the additional analysis, the patients in the poster-exposed group showed greater improvements in the health outcomes, compared with the non-exposed group, although the effects were statistically non-significant within this study's one-month period. A poster with pictorial information was effective in increasing awareness about dysphagia-specific information among caregivers of patients in inpatient care and can be used as an augmentative means of information, with potential benefits for patient safety and rehabilitation.

The effect of a family-centered advance care planning intervention for persons with cognitive impairment and their family caregivers on end-of-life care discussions and decisions

Advanced care planning (ACP) includes advance directives (AD), which can specify provisions for palliative care and types of life-sustaining treatments for an individual requiring end-of-life (EoL) care. ACP for persons in the early stages of cognitive decline can decrease anxiety and conflict for family members needing to make decisions about EoL-care, which is especially critical for family caregivers (FCGs) if they play a role as a surrogate regarding healthcare decisions. However, ACP for persons with cognitive impairment (PWCIs) is often overlooked. This study explored the effects of a family-centered ACP intervention on decisions about EoL-care, life-sustaining treatment decisions, and discussions of related topics among PWCIs and FCGs. The study was conducted in outpatient clinics of regional teaching hospitals in northern Taiwan. Participants were dyads consisting of persons diagnosed with mild cognitive impairment or mild dementia and their FCGs. The family-centered ACP intervention was provided by an ACP-trained senior registered nurse. A one-group, pretest–posttest design was used to evaluate the effect of the intervention on 44 dyads. Four structured questionnaires collected data regarding familiarity with ACP, intention to engage in ACP, participation in personal discussions between the dyads about ACP, and consistency between PWCIs and FCGs for decisions about life-sustaining treatments at EoL. Paired t, Kappa, and McNemar tests were used to compare differences between pre-intervention data (pretest) and post-intervention data (posttest). There were significant increases in familiarity with ACP, components of ACP, and the number of topics PWCIs and FCGs personally discussed surrounding EoL-care decisions. There was no change for either group in wanting to have a formal ACP consultation and only modest increases in consistency between PWCIs and FCGs for life-sustaining treatment decisions after completion of the family-centered ACP intervention. Clinicians caring for PWCIs should incorporate family-centered ACP interventions and support ongoing discussions about life-sustaining medical treatments to ensure their preferences regarding EoL-care are respected. The accessibility and availability of consultations about ACP should also be provided.

The use of visual methods to support communication with older adults with cognitive impairment: A scoping review

Older adults with cognitive impairment often face difficulties with comprehension and communication, which can impact other cognitive processes such as decision-making. This scoping review investigates how visual methods can support older adults with cognitive impairment. The review involved querying four databases. From these databases, eleven articles fit inclusion criteria. This paper examines the purposes, use contexts, types, and effectiveness of the visual methods described in each study. The two major use contexts were elicitation of thoughts, feelings, and preferences in everyday life and health/healthcare related uses. Studies that used visual methods for eliciting preferences generally employed static visualizations. Health-related contexts employed more complex and interactive visualizations. Three studies used visual tools to support older adults in understanding; six, communication; and three, decision-making. None addressed all three outcomes of interest. This study provides recommendations and future directions for visual communication research with older adults with cognitive impairment.

How Effective are Pictures in Eliciting Information from People Living with Dementia? A Systematic Review

OBJECTIVES

Decline in language and cognitive functioning often deprives people living with moderate-to-severe dementia of self-reporting their quality of life (QoL) on the written and verbal formats of questionnaires. This systematic review aimed to evaluate the effectiveness of pictorial tools as an alternative method for enabling people living with dementia to self-report their QoL.

METHODS

PubMed, PsycINFO, CINAHL, and EMBASE were searched. Primary research studies reporting on information elicitation from people living with dementia through pictures were deemed eligible. Six studies satisfied the inclusion criteria. Methodological quality of the studies was evaluated through Downs and Black checklist. Data was extracted according to population, intervention, comparator, and outcomes (PICO) and results were summarized and supplemented by narrative synthesis.

RESULTS

Compared to usual communication methods, pictorial tools were found to have a superior effect on comprehension of conversations and decision-making abilities, minimal effect on preference consistency, and an undeterminable effect on discourse features.

CONCLUSIONS

There is consistent evidence that pictures enhance comprehension and might facilitate decision-making abilities.

CLINICAL IMPLICATIONS

QoL information can be elicited more effectively through pictorial tools. Future studies warrant development of pictorial versions of standardized QoL tools which will assist the inclusion of people living with severe dementia.

Examining Face Validity of Visual Stimuli Used in Preference Assessments for Older Adults With Communication Impairments

PURPOSE

Preference assessment is integral to person-centered treatment planning for older adults with communication impairments. There is a need to validate photographs used in preference assessment for this population. Therefore, this study aimed to establish preliminary face validity of photographs selected to enhance comprehension of questions from the Preferences for Everyday Living Inventory-Nursing Home (PELI-NH) and describe themes in older adults' recommendations for revising photographic stimuli.

METHOD

This qualitative, cognitive interviewing study included 21 participants with an average age of 75 years and no known cognitive or communication deficits. Photographic stimuli were randomized and evaluated across one to two interview sessions. Participants were asked to describe what the preference stimuli represented to them. Responses were scored to assess face validity. Participants were then shown the PELI-NH written prompt and asked to evaluate how well the photograph(s) represented the preference. A semideductive thematic analysis was conducted on interview transcripts to summarize themes in participant feedback.

RESULTS

Forty-six (64%) stimuli achieved face validity criteria without revisions. Six (8%) stimuli achieved face validity after one partial revision. Twenty (28%) stimuli required multiple revisions and reached feedback saturation, requiring team review for finalization. Thematic analysis revealed challenges interpreting stimuli (e.g., multiple meanings) and participant preferences for improving photographs (e.g., aesthetics).

CONCLUSIONS

Cognitive interviewing was useful for improving face validity of stimuli pertaining to personal care topics. Abstract and subjective preferences (e.g., cultural traditions) may be more challenging to represent. This study provides a framework for further testing with older adults with cognitive, communication, and hearing impairments.

A Seat at the Table: Supporting Persons with Severe Dementia in Communicating Their Preferences

Objective: Persons with severe dementia are less likely to have a role in preference assessment due to communication challenges associated with the disease. Research is limited on how to support preference communication while using existing preference assessment tools (e.g., the Minimum Data Set 3.0).Methods: This study examined the effect of two assessment conditions (standard verbal; visual-and-text supported;) on residents' (N = 21) social and leisure preference consistency over 1-week and utterance types (acknowledgment, elaboration, off-topic, request for clarification) in response to preference questions. Residents with severe dementia were recruited from four nursing homes (n = 11) and three assisted living facilities (n = 10). As a preliminary measure of provider acceptability and social validity, a sample of 10 naïve judges (University students) listened to the interviews and rated residents' communication clarity and their confidence with understanding residents' preferences.Results: Neither assessment condition promoted significantly greater levels of consistency (i.e., the same preference rating at Time 1 and Time 2). Residents expressed significantly fewer requests for clarification in the visual-and-text supported condition. Naïve judges rated residents' communication positively, with no significant differences between conditions.Conclusions: This study addresses a gap in current research and holds important implications for enhancing care planning participation by residents with severe dementia.Clinical Implications: Residents with severe dementia can successfully participate in activity preference discussions without proxy participation. Residents may comprehend interview questions better when provided in a supported format.

Cognitive decline, sensory impairment, and the use of audio-visual aids by long-term care facility residents

BACKGROUND

Hearing and vision impairments and the use of audio-visual aids are associated with cognitive decline in community-dwelling older people, but effects in long-term care facilities (LFCF) are unclear. We hypothesize that visual and hearing impairment are associated with cognitive decline and these relationships are mediated by using visual and hearing aids.

METHODS

Secondary data analysis of a longitudinal study was conducted in the 7 government-subsidized LTCF operated by one of the largest non-governmental organizations in Hong Kong using data between 2005 and 2016. Eligible residents were ≥ 60 years of age without severe cognitive impairment at baseline who had stayed in the facilities for more than 3 years. All variables were measured by using the Minimum Data Set-Resident Assessment Instrument Version 2.0, Hong Kong version. The outcome was cognitive decline. Predictors were visual and hearing impairments. Mediators were the use of visual and hearing aids. General linear models were employed to test the hypotheses.

RESULTS

Results for 2,233 residents were analyzed, with a mean age of 82.1 ± 8.2 years and a mean follow-up period of 4.4 ± 0.8 years. Results showed that those who had visual impairment (p = 0.004) and hearing impairments (p = 0.022) had a higher risk of cognitive decline. Using hearing aids (coefficient = 0.0186, p < 0.05) positively mediates the effect of hearing impairment on cognitive decline. Using visual aids (coefficient = -0.0881, p < 0.05) negatively mediates the effects of visual impairment on cognitive decline.

CONCLUSION

In LTCF, hearing and visual impairments are associated with a higher risk of cognitive decline. Hearing aids often-users were associated with a higher risk of cognitive decline. LTCF residents with visual impairment did not use visual aids. Use of visual aids demonstrated potential effects in slowing cognitive decline. A future study with a larger and more diverse sample with attention to quality of devices is proposed to confirm its effects.

Feasibility and acceptability of a web-based advance care plan for dementia

While advance care planning (ACP) can help elicit preferences and is associated with improved end-of-life outcomes, persons living with dementia (PLWD) in nursing homes are rarely included in ACP. Web-based decision aids are a readily available tool to engage PLWD in ACP, but none are designed for the unique needs of PLWD, particularly those residing in nursing homes. Our Memory Care Wishes (OMCW) was adapted from a publicly available web-based ACP tool in collaboration with dementia care experts. This study aimed to explore the acceptability of OMCW. We used a convergent, mixed methods design to describe PLWD and surrogates' experiences using the OMCW website. Participants described ease of use, comfort with viewing, helpfulness for planning, and likelihood to recommend. Overall, OMCW is acceptable, however, PLWD continue to have difficulties understanding and engaging with some website content. Modifications were incorporated based on these findings, setting the stage for implementation and effectiveness testing.

The "Counseling+" Roles of the Speech-Language Pathologist Serving Older Adults With Mild Cognitive Impairment and Dementia From Alzheimer's Disease

Purpose

Persons with dementia and mild cognitive impairment (MCI) are major consumers of services provided by speech-language pathologists (SLPs). These services include not only direct assessment and treatment of communication and swallowing but also counseling, collaboration, prevention, and wellness. These "counseling+" activities can be especially challenging for SLPs to deliver because of the lack of evidence, as well as the complex nature of Alzheimer's disease (AD) and other conditions that cause MCI and dementia.

Method

This tutorial is written by a speech-language pathologist, a neuropsychologist, and a geriatric psychiatrist to provide education, resources, and recommendations for SLPs delivering counseling+ activities to patients with MCI and dementia from AD and related disorders.

Results and Conclusions

We describe counseling+ activities across the continuum of care ranging from educating and conducting cognitive screenings with adults experiencing age-related cognitive decline to supporting end-of-life wishes. Because of their expertise in communication, SLPs can provide an array of important leading and supporting services to patients, their family, and other health care professionals on the care team, such as providing patients with appropriate feedback following a cognitive screening and helping caregivers identify the communicative intent of a responsive behavior. The demand for SLP services for patients with MCI and dementia will grow significantly over the next few decades, necessitating more systematic research and clinical evidence in this area.

Effects of multimedia-based fall prevention education on the knowledge, attitudes, or behaviors of patients

OBJECTIVES

Patient safety is regarded as a critical quality monitoring indicator for medical institutions. The effects of a multimedia-based patient education intervention on knowledge, attitudes, and behaviors regarding fall prevention were observed.

METHODS

The study had a quasi-experimental research design and enrolled 140 participants. Seventy participants in the experimental group received multimedia-based patient education and a health education leaflet, while those in the control group received only the health education leaflet. A structured questionnaire was used for data collection at baseline, and a posttest was applied after the intervention.

RESULTS

The participants were predominantly treated in the gastroenterology department (45.7%), followed by the pulmonology department (33.6%). A total of 86.4% of patients had not experienced a fall within 3 months. After the intervention, the average scores for all variables in the experimental group were higher than those in the control group. The results indicate that attitudes, knowledge, and behaviors regarding fall prevention among patients in the pulmonology department were higher than those among patients in the gastroenterology department; the differences were statistically significant.

CONCLUSION

The individualized health education content was of substantial significance for patients with different disease backgrounds and facilitated changes in their knowledge, attitudes, and behaviors regarding falls.

RELEVANCE TO CLINICAL PRACTICE

Multimedia-based patient education influenced inpatients' knowledge, attitudes, and behaviors for preventing falls.

Integration of Health Information Technology and Promotion of Personhood in Family-Centered Dementia Care: Intervention Trial

Alzheimer's disease and related dementias (ADRD) often result in communication deficits that can lead to negative health outcomes as well as complications for caregiving and clinical care. Although augmentative and alternative communication (AAC) devices have demonstrated efficacy in assisting persons living with dementia (PLWD) in communicating, few devices offer customization for the person's care preferences (e.g., clothing, food, activities) or are designed for integration into clinical care and caregiving. To address this issue, our research team is developing a novel electronic AAC prototype with a touchscreen to promote communication and personhood for PLWD. The current article describes the development of this technology and uses the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 Statement to describe the clinical trial that is planned to test its efficacy.

TARGETS

PLWD and their care partners.

INTERVENTION DESCRIPTION

Use of AAC Plus to promote communication and personhood for PLWD.

MECHANISMS OF ACTION

AAC Plus will provide PLWD and care partners a way to communicate PLWD's daily preferences and provide clinical data for health care providers.

OUTCOMES

Determine whether enhanced communication of daily preferences of PLWD will improve quality of life of PLWD and their care partners.

Dental informed consent challenges and considerations for cognitively impaired patients

Because the US population is living to an older age, the number of individuals with cognitive impairment and periodontitis is increasing, as both conditions/diseases increase with age. Dental informed consent best practices for dental/periodontal treatment of individuals with cognitive impairment have not been explored, yet warrant consideration, because complex dental treatments to address periodontal needs/edentulism raise challenges for informed consent in the elderly with cognitive impairment. The purpose of this review is to help practitioners better understand this topic and develop best practices in dentistry for informed consent of patients with cognitive impairment that need extensive dental treatment, including surgical and implant therapy.

Advance care planning information intervention for persons with mild dementia and their family caregivers: Impact on end-of-life care decision conflicts

Persons with dementia are at high risk for loss of decision-making ability due to increased cognitive decline as the disease progresses. Participation in advance care planning (ACP) discussions in the early stages of dementia is crucial for end-of-life (EoL) decision-making to ensure quality of EoL care. A lack of discussions about ACP and EoL care between persons with dementia and family caregivers (FCGs), can lead to decisional conflicts when persons with dementia are in the later stages of the disease. This study explored the effects of a family-centered ACP information intervention among persons with dementia and FCGs. The study was conducted in outpatient clinics in Taiwan. Participants were dyads (n = 40) consisting of persons diagnosed with mild cognitive impairment or mild dementia and their FCGs. A one-group, pretest–posttest, pre-experimental design was employed. The intervention was provided by an ACP-trained senior registered nurse and was guided by ACP manuals and family-centered strategies. Outcome data were collected with four structured questionnaires regarding knowledge of end-stage dementia treatment, knowledge of ACP, attitude towards ACP, and EoL decisional conflict about acceptance or refusal of cardiopulmonary resuscitation, ventilators, and tracheostomy. Paired t tests compared differences between pre-intervention data and 4-weeks’ post-intervention data. The intervention resulted in significant improvements among persons with dementia and FCGs for knowledge of end-stage dementia treatment (p = .008 and p < .001, respectively), knowledge of ACP (both p < .001), and significant reductions in decisional conflicts (both p < .001). Scores for positive and negative attitude toward ACP did not change for persons with dementia; however, there was a reduction in negative attitude for FCGs (p = .001). Clinical care for persons with dementia should incorporate ACP interventions that provide knowledge about EoL dementia care using family-centered care strategies that facilitate regular and continuous communication between FCGs, persons with dementia, and medical personnel to reduce decisional conflicts for EoL care.
