Ready or Not: A Conceptual Model of Organizational Readiness for Embedded Pragmatic Dementia Research.

The National Institute on Aging Alzheimer's Disease/Alzheimer's Disease and Related Dementias Research Implementation Milestones emphasize the need for implementation research that maximizes up-take and scale-up of evidence-based dementia care practices across settings, diverse populations, and disease trajectories. Organizational readiness for implementation is a salient consideration when planning and conducting embedded pragmatic trials, in which interventions are implemented by provider staff. The current article examines the conceptual and theoretical underpinnings of organizational readiness for implementation and the operationalization of this construct. We offer a preliminary conceptual model for explicating and measuring organizational readiness and describe the unique characteristics and demands of implementing evidence-based interventions targeting persons with dementia and/or their care partners.

Antimicrobial photodynamic therapy for the treatment of oral infections: A systematic review.

Oral infection is a common clinical symptom. While antibiotics are widely employed as the primary treatment for oral diseases, the emergence of drug-resistant bacteria has necessitated the exploration of alternative therapeutic approaches. One such modality is antimicrobial photodynamic therapy (aPDT), which utilizes light and photosensitizers. Indeed, aPDT has been used alone or in combination with other treatment options dealing with periodontal disease for the elimination of biofilms from bacterial community to achieve bone formation and/or tissue regeneration. In this review article, in addition to factors affecting the efficacy of aPDT, various photosensitizers, the latest technology and perspectives on aPDT are discussed in detail. More importantly, the article emphasizes the novel design and clinical applications of photosensitizers, as well as the synergistic effects of chemical and biomolecules with aPDT to achieve the complete eradication of biofilms and even enhance the biological performance of tissues surrounding the treated oral area.

Mealtime interactions between nursing home staff and residents with dementia: a behavioral analysis of Language characteristics.

BACKGROUND: Quality staff-resident communication is crucial to promote outcomes in nursing home residents with dementia requiring assistance during mealtimes. Better understanding of staff-resident language characteristics in mealtime interactions help promote effective communication, yet evidence is limited. This study aimed to examine factors associated with language characteristics in staff-resident mealtime interactions. METHODS: This was a secondary analysis of 160 mealtime videos involving 36 nursing staff and 27 residents with moderately severe to severe dementia in 9 nursing homes. Mixed-effects models was used to examine the relationships between factors and language characteristics in staff-resident mealtime interactions. The independent variables were speaker (resident vs. staff), utterance quality (negative vs. positive), intervention (pre- vs. post-communication intervention), and resident dementia stage and comorbidities. The dependent variables were expression length (number of words in each utterance) and addressing partner by name (whether staff or resident named their partner in each utterance). All models included staff, resident, and staff-resident dyad as random effects. RESULTS: Staff (utterance n = 2990, 99.1% positive, mean = 4.3 words per utterance) predominated conversations and had more positive, longer utterances than residents (utterance n = 890, 86.7% positive, mean = 2.6 words per utterance). As residents progressed from moderately severe to severe dementia, both residents and staff produced shorter utterances (z=-2.66, p = .009). Staff (18%) named residents more often than residents (2.0%; z = 8.14, p < .0001) and when assisting residents with more severe dementia (z = 2.65, p = .008). CONCLUSIONS: Staff-resident communication was primarily positive, staff-initiated, and resident-oriented. Utterance quality and dementia stage were associated with staff-resident language characteristics. Staff play a critical role in mealtime care communication and should continue to initiate resident-oriented interactions using simple, short expressions to accommodate resident declining language abilities, particularly those with severe dementia. Staff should practice addressing residents by their names more frequently to promote individualized, targeted, person-centered mealtime care. Future work may further examine staff-resident language characteristics at other levels of language using more diverse samples.

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.

Mealtime Interactions between Nursing Home Staff and Residents with Dementia: A Behavioral Analysis of Language Characteristics.

Background. Quality staff-resident communication is crucial to promote outcomes in nursing home residents with dementia requiring assistance during mealtimes. Better understanding of staff-resident language characteristics in mealtime interactions help promote effective communication, yet evidence is limited. This study aimed to examine factors associated with language characteristics in staff-resident mealtime interactions. Methods. This was a secondary analysis of 160 mealtime videos involving 36 staff and 27 residents with dementia (53 unique staff-resident dyads) in 9 nursing homes. We examined the associations of speaker (resident vs. staff), utterance quality (negative vs. positive), intervention (pre- vs. post-communication intervention), and resident dementia stage and comorbidities with expression length (number of words in each utterance) and addressing partner by name (whether staff or resident named their partner in each utterance), respectively. Results. Staff (utterance n = 2990, 99.1% positive, mean = 4.3 words per utterance) predominated conversations and had more positive, longer utterances than residents (utterance n = 890, 86.7% positive, mean = 2.6 words per utterance). As residents progressed from moderately-severe to severe dementia, both residents and staff produced shorter utterances (z=-2.66, p = .009). Staff (18%) named residents more often than residents (2.0%; z = 8.14, p < .0001) and when assisting residents with more severe dementia (z = 2.65, p = .008). Conclusions. Staff-resident communication was primarily positive, staff-initiated, and resident-oriented. Utterance quality and dementia stage were associated with staff-resident language characteristics. Staff play a critical role in mealtime care communication and should continue to initiate resident-oriented interactions using simple, short expressions to accommodate resident declining language abilities, particularly those with severe dementia. Staff should practice addressing residents by their names more frequently to promote individualized, targeted, person-centered mealtime care. Future work may further examine staff-resident language characteristics at word and other levels using more diverse samples.

Delirium and Behavioral Symptoms in Persons With Dementia at Hospital Admission: Mediating Factors.

BACKGROUND: Hospitalized persons with dementia are at risk of delirium with behavioral symptoms, predisposing them to a higher rate of complications and caregiver distress. The purpose of this study was to examine the relationship between delirium severity in patients with dementia upon admission to the hospital and the manifestation of behavioral symptoms, and to evaluate the mediating effects of cognitive and physical function, pain, medications, and restraints. METHODS: This descriptive study used baseline data from 455 older adults with dementia enrolled in a cluster randomized clinical trial that tested the efficacy of family centered function-focused care. Mediation analyses were conducted to determine the indirect effect of cognitive and physical function, pain, medications (antipsychotics, anxiolytics, sedative/hypnotics, narcotics, and number of medications), and restraints on behavioral symptoms, controlling for age, sex, race, and educational level. RESULTS: The majority of the 455 participants were female (59.1%), had an average age of 81.5 (SD=8.4), were either white (63.7%) or black (36.3%), and demonstrated one or more behavioral symptoms (93%) and delirium (60%). Hypotheses were partially supported in that physical function, cognitive function, and antipsychotic medication partially mediated the relationship between delirium severity and behavioral symptoms. CONCLUSION: This study provides preliminary evidence identifying antipsychotic use, low physical function, and significant cognitive impairment as specific targets for clinical intervention and quality improvement in patients with delirium superimposed on dementia at hospital admission.

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.

Gender differences in interactions and depressive symptoms among hospitalized older patients living with dementia.

Alzheimer's disease or a related dementia (ADRD) disproportionately affects women with two-thirds of individuals with ADRD comprised of women. This study examined gender-related differences in the quality of staff-patient interactions and depressive symptoms among hospitalized older patients living with dementia. This secondary analysis utilized baseline data of 140 hospitalized older patients with dementia who participated in the final cohort of a randomized controlled trial (ClinicalTrials.gov identifier: NCT03046121) implementing Family centered Function-focused Care (Fam-FFC). On average, the participants (male = 46.1%, female = 52.9%) were 81.43 years old (SD = 8.29), had positive interactions with staff and lower depressive symptoms based on Quality of Interaction Schedule (QUIS) scores and Cornell Scale for Depression in Dementia (CSDD) scores, respectively. Although males had more positive interactions (male = 6.06, SD = 1.13; female = 5.59, SD = 1.51) and lesser depressive symptoms (male = 7.52, SD = 4.77; female = 8.03, SD = 6.25) than females, no statistically significant gender differences were observed in linear models with appropriate covariates or multivariant analysis of covariant (MANCOVA). However, the multigroup regression conducted to further probe marginally significant moderation effect of gender and pain on staff-patient interactions demonstrated that greater pain was significantly related to lower quality or less positive staff-patient interactions for females compared to males (χ2diff (1) = 4.84, p = .03). Continued evaluation of gender differences is warranted to inform care delivery and interventions to improve care for hospitalized older patients with dementia.

Cognitive Exercise for Persons with Alzheimer's Disease and Related Dementia Using a Social Robot.

Reminiscence therapy (RT) can improve the mood and communication of persons living with Alzheimer's Disease and Alzheimer's Disease related dementias (PLWD). Traditional RT requires professionals' facilitation, limiting its accessibility to PLWD. Social robotics has the potential to facilitate RT, enabling accessible, home-based RT. However, studies are needed to investigate how PLWD would perceive a robot-mediated RT (RMRT) and how to develop RMRT for positive user experience and successful adoption. In this paper, we developed a prototype of RMRT using a humanoid social robot and tested it with 12 participants (7 PLWD, 2 with mild cognitive impairment, and 3 informal caregivers). The robot automatically displayed a memory trigger on its tablet and engaged participants in a relatable conversation during RMRT. A mixed-method approach was employed to assess its acceptability and usability. Our results showed that PLWD had an overall positive user experience with the RMRT. Participants laughed and sang along with the robot during RMRT and demonstrated intention to use it. We additionally discussed robot control method and several critical problems for RMRT. The RMRT can facilitate both verbal and nonverbal social interaction for PLWD and holds promise for engaging, personalized, and efficient home-based cognitive exercises for PLWD.

Well-Being Benefits of Horticulture-Based Activities for Community Dwelling People with Dementia: A Systematic Review.

Most people living with dementia in the early-to-middle stages live in the community or in their own homes and engagement in enjoyable activities is fundamental to maintaining quality of life and autonomy. Horticulture-based activities are beneficial for the health and well-being for people living with dementia ("PLWD") in residential care settings, yet evidence within community settings, where the majority live, has not been comprehensively synthesized. A mixed studies systematic review protocol was registered and a systematic search conducted to June 2022 across MEDLINE, COCHRANE, Web of Science, Embase, Psycnet, CINAHL, PsycINFO databases, using terms relating to dementia and horticulture. Original studies examining group or individual horticulture-based programs for community-dwelling PLWD were included. Forty-five articles were selected for full review, eight met inclusion criteria and were retained for data extraction. Evidence from three mixed methods, two quantitative, two qualitative, and one case study design, involving a total of 178 community dwelling PLWD, was narratively summarized. Findings revealed that involvement in horticulture-based activities led to positive impacts on engagement, social interactions, and mental and physical well-being in PLWD. No conclusive evidence was found from included studies for improvement in cognitive function. As most studies to date have concentrated on PLWD in long-term care settings, future research should evaluate the effect of these types of activities in a more rigorous intervention design in community settings.

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.

Prevalence and predictors of depressive symptoms in older adults with cancer.

INTRODUCTION: Older adults with cancer are at risk of developing depressive symptoms. However, little is known about the prevalence and predictors of depressive symptoms in older adults with cancer. MATERIALS AND METHODS: This study examined the prevalence and predictors of depressive symptoms among older adults with cancer in the United States using the data from the 2012 and 2014 wave of the Health and Retirement Study. This analysis included 1799 older adults aged 65 and over with a self-reported diagnosis of cancer. Multivariate regression analysis was used to examine the predictors of depressive symptoms. The main predictors included age, gender, race, education, marital status, chronic conditions, and functional limitations. RESULTS: Results revealed that the prevalence of depressive symptoms in older adults with cancer was 14.9%. Results of Poisson regression revealed that greater age, belonging to a race other than White or African American, not being married, presence of more chronic conditions, and higher levels of functional limitations were associated with higher levels of depressive symptoms. DISCUSSION: The prevalence of depressive symptoms is high in older adults with cancer and several factors predict depressive symptoms in this population. Individuals who are at high risk of developing depressive symptoms should be identified and appropriate timely interventions should be initiated to reduce the rates of depressive symptoms in older adults with cancer.

Chronic conditions and depressive symptoms in older adults: the mediating role of functional limitations.

BACKGROUND: Depressive symptoms, chronic conditions, and functional limitations are common in older adults. Several studies have examined the relationship between chronic conditions or functional limitations and depressive symptoms separately. However, little is known about how much of the effect of chronic conditions on depressive symptoms is due to the functional limitations resulting from such conditions. METHODS: This paper examined the longitudinal association of chronic conditions and functional limitations with depressive symptoms in older adults aged 65 and over in the USA using the data from the 2012 wave and 2014 wave of the Health and Retirement Study (HRS). Mediation analysis was used to examine the mediation effects of 2012 functional limitations on the relationship between 2012 chronic conditions and 2014 depressive symptoms controlling for other measures including gender, age, race, education, marital status, and BMI. RESULTS: Results revealed that chronic conditions and functional limitations were significantly associated with depressive symptoms. There was a 13.7% mediation effect when 2012 functional limitations were added as a mediator on the relationship between 2012 chronic conditions and 2014 depressive symptoms. CONCLUSION: Functional limitations mediate the relationship between chronic conditions and depressive symptoms. Preventing or managing functional limitations may help reduce depressive symptoms in older adults with chronic conditions.

Function-Focused Person-Environment Fit for Long-Term Care Residents With Dementia: Impact on Apathy.

BACKGROUND AND OBJECTIVES: Apathy is a common symptom in dementia and is associated with rapid cognitive decline, poor quality of life, and higher mortality. Lawton's Competence and Environmental Press model suggests that an individual's behavior and affect are influenced by the fit of their functional abilities with the environmental demands. Yet, empirical evidence on the association between person-environment (P-E) fit and apathy is lacking. Thus, this study examined the relationship between P-E fit and apathy in dementia. Specifically, this study focused on the extent the physical environment fits individual functional limitations. RESEARCH DESIGN AND METHODS: This is a cross-sectional study using the baseline data from long-term care residents with dementia. The sample included 199 residents with moderate-to-severe cognitive impairment from 4 assisted living and 4 nursing homes. Function-focused P-E fit was measured using the Housing Enabler scale. Apathy was measured using the Apathy Evaluation Scale. Multilevel linear models were used to analyze the relationship between P-E fit and apathy. RESULTS: Findings revealed that greater P-E fit, specifically indoor environment, was significantly associated with lower apathy after controlling for age, gender, and years living in the facility. Yet, the association became not significant after controlling for individual physical function. DISCUSSION AND IMPLICATIONS: Findings support the association between function-focused P-E fit and apathy, but the association is no longer significant after physical function is adjusted. Future research may explore other aspects of P-E fit and the impact of social and organizational environment on apathy in dementia.

Reliability and Validity Testing of the Assessment of the Environment for Person-Centered Management of BPSD and Assessment of Policies for Person-Centered Management of BPSD Measures.

The purpose of this study was to test the reliability and validity of the Assessment of the Environment for Person-Centered Management of BPSD and the Assessment of Policies for Person-Centered Management of BPSD. The sample included 35 long term care facilities. There was evidence of reliability based on internal consistency and test-retest reliability of both measures. There was some evidence of validity based on Rasch model testing and INFIT and OUTFIT statistics. Across both measures there were six items with that were endorsed as present by all facilities. The INFIT and OUTFIT statistics were all within the expected range of .5 to 1.5 with the exception of four high OUTFIT statistics for the Assessment of the Environment for Person-Centered Management of BPSD. For the Assessment of Policies for Person-Centered Management of BPSD there were two items that had high INFIT statistics and six with low OUTFIT statistics and one with high OUTFIT statistics. Measure revisions are suggested including removal of some poor fitting items, items with no variance, and adding items to differentiate those very high in evidence of environments and policies that manage BPSD.

Barriers to palliative and hospice care utilization in older adults with cancer: A systematic review.

The number of older adults with cancer and the need for palliative care among this population is increasing in the United States. The objective of this systematic review was to synthesize the evidence on the barriers to palliative and hospice care utilization in older adults with cancer. A systematic literature search was conducted using PubMed, CINAHL, PsycINFO, Embase, and Cochrane Library databases (from inception to 2018) in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Research articles that examined palliative or hospice care utilization in older adults with cancer were included in this review. Fineout-Overholt's Level of Evidence was used for quality appraisal. A total of 19 studies were synthesized in this review. Barriers to palliative and hospice care utilization were categorized into socio-demographic barriers, provider-related barriers, and health insurance-related barriers. Findings revealed that male, racial minority, unmarried individuals, individuals with low socio-economic status or residing in rural areas, and fee-for-service enrollees were less likely to use palliative or hospice care. Lack of communication with care providers is also a barrier of using palliative or hospice care. The factors identified in this review provide guidance on identification of high-risk population and intervention development to facilitate the use of palliative and hospice care in older adults with cancer. Larger prospective studies on this topic are needed to address this critical issue.

Factors influencing the pace of food intake for nursing home residents with dementia: Resident characteristics, staff mealtime assistance and environmental stimulation.

AIM: To examine the association of resident characteristics, staff mealtime assistance and environmental stimulation with the pace of food intake. DESIGN: A secondary analysis of 36 baseline eating videos involving 19 nursing assistants and 15 residents with dementia in eight nursing homes from a communication intervention study. METHODS: The outcome variable was the pace of food intake (the number of bites and drinks per minute). The exploratory variables were resident characteristics (age, gender, dementia stage and eating performance), staff mealtime assistance (frequency of verbal, visual, partial and full physical assistance) and environmental stimulation. Multi-level models were used to examine the association. RESULTS: A faster pace of food intake is associated with being male, better eating performance, staff provision of visual and physical assistance and better quality of environmental stimulation that involved interaction. The pace of food intake was not associated with resident age, staff verbal assistance or partial physical assistance.
