Nature-themed video intervention may improve cardiovascular safety of psilocybin-assisted therapy for alcohol use disorder

Introduction

Psychedelic-assisted therapy with psilocybin has shown promise in Phase 2 trials for alcohol use disorder (AUD). Set and setting, particularly factors facilitating a connection with nature, may positively influence the psychedelic experience and therapeutic outcomes. But to date, randomized controlled trials of interventions to enhance set and setting for psychedelic-assisted therapy are lacking.

Methods

This was a pilot randomized, controlled trial of Visual Healing, a nature-themed video intervention to optimize set and setting, versus Standard set and setting procedures with two open-label psilocybin 25 mg dosing sessions among 20 participants with AUD. For the first session, participants randomized to Visual Healing viewed nature-themed videos during the preparation session and the "ascent" and "descent" phases of the psilocybin dosing session while participants randomized to the Standard condition completed a meditation during the preparatory session and wore eyeshades and listened to a music playlist throughout the dosing session. For the second session 4 weeks later, participants chose either Visual Healing or Standard procedures. Primary outcomes were feasibility, safety, and tolerability of Visual Healing. Secondary and exploratory outcomes were changes in alcohol use, psychedelic effects, anxiety and stress.

Results

Nineteen of 20 (95%) randomized participants (mean age 49 ± 11 years, 60% female) completed the 14-week study. During the first psilocybin session, participants viewed an average of 37.9 min of the 42-min video and there were no video-related adverse events. Peak increase in post-psilocybin blood pressure was significantly less for participants randomly assigned to Visual Healing compared to Standard procedures. Alcohol use decreased significantly in both Visual Healing and Standard groups and psychedelic effects, stress, and anxiety were similar between groups.

Discussion

In this open-label pilot study, viewing Visual Healing videos during preparation and psilocybin dosing sessions was feasible, safe, and well-tolerated among participants with AUD. Preliminary findings suggest that Visual Healing has potential to reduce the cardiovascular risks of psychedelic therapy, without interfering with the psychedelic experience or alcohol-related treatment outcomes. Studies to replicate our findings as well as studies of different set and setting interventions with other psychedelic medications and indications are warranted.

A Virtual Reality Intervention to Reduce Dementia-Related Agitation Using Single-Case Design

OBJECTIVES

The primary objective of this study was to use a single-case design to evaluate the utility of a VR intervention to reduce agitation behaviors in two female participants with a diagnosis of dementia.

METHODS

A single-case research design with an ideographic approach was selected given the novelty of this intervention. A blended single case experimental design was used combining the Multiple-baseline design across individuals with a reversal design to examine the effects of VR nature scenes on agitation. Visual analysis was used to determine changes in mean, level, and latency of the behaviors.

RESULTS

For both participants, a significant decrease in their respective agitation behaviors was observed during intervention phases.

CONCLUSIONS

This study provides preliminary evidence of the utility of VR as a brief and effective intervention to decrease agitation in individuals with dementia.

CLINICAL IMPLICATIONS

These initial, promising results may help caregivers improve the quality of life for dementia patients. Further, the brevity of the intervention makes this a practical tool for care providers working in clinical settings. The primary objective of this study was to use a single-case design to evaluate the utility of a VR intervention to reduce agitation behaviors in two female participants with a diagnosis of dementia.

Patients' Health & Well-Being in Inpatient Mental Health-Care Facilities: A Systematic Review

Background: Previous research indicates that the physical environment of healthcare facilities plays an important role in the health, well-being, and recovery outcomes of patients. However, prior works on mental healthcare facilities have incorporated physical environment effects from general healthcare settings and patient groups, which cannot be readily transferred to mental healthcare settings or its patients. There appears to be a specific need for evidence synthesis of physical environmental effects in mental healthcare settings by psychopathology. Purpose: This review evaluates the state (in terms of extent, nature and quality) of the current empirical evidence of physical environmental on mental health, well-being, and recovery outcomes in mental healthcare inpatients by psychopathology. Method: A systematic review (PRISMA guidelines) was performed of studies published in English, German, Dutch, Swedish, and Spanish, of all available years until September 2020, searched in Cochrane, Ovid Index, PsycINFO, PubMed, and Web of Science and identified through extensive hand-picking. Inclusion criteria were: Adult patients being treated for mental ill-health (common mental health and mood disorders, Cochrane frame); inpatient mental health care facilities; specifications of the physical and socio-physical environment (e.g., design features, ambient conditions, privacy); all types of empirical study designs. Quality assessment and data synthesis were undertaken. Results: The search retrieved 1,068 titles of which 26 met the inclusion criteria. Findings suggest that there is only indicative evidence of the impact of the physical healthcare environment on patients' mental health, well-being, and recovery outcomes. There is significant lack of pathology-specific evidence. Methodological shortcomings and empirical scarcity account for the poor evidence. Conclusion: This review highlights the need for more research using advanced study designs.

Pilot Study of a Digital Screen-Based Calming Device for Managing Resistance During Morning and Evening Care of Persons With Dementia

Resistance to care is among the most common behaviors exhibited by persons with dementia (PwD). Resistance to care is a barrier to safety and comfort of PwD and caregivers. Nonpharmacological interventions are recommended as first-line management. In the current study, 13 long-term care (LTC) residents aged 74 to 100 years with a history of behavioral and psychological symptoms of dementia (BPSD) were randomized to intervention (n = 7) and control (n = 6) groups. On Days 1 to 3, the intervention group received usual care plus exposure to MindfulGarden (MG), a novel digital calming device during morning and evening care, activities widely recognized as problematic for PwD and staff; the control group received usual care only. On Day 4, both groups were exposed to MG with verbal prompting. Trends in the data suggest that MG reduced BPSD and duration of care in the morning and may be a useful tool in management of resistance to routine care in PwD in LTC settings.

Neurofeedback and the Aging Brain: A Systematic Review of Training Protocols for Dementia and Mild Cognitive Impairment

Dementia describes a set of symptoms that occur in neurodegenerative disorders and that is characterized by gradual loss of cognitive and behavioral functions. Recently, non-invasive neurofeedback training has been explored as a potential complementary treatment for patients suffering from dementia or mild cognitive impairment. Here we systematically reviewed studies that explored neurofeedback training protocols based on electroencephalography or functional magnetic resonance imaging for these groups of patients. From a total of 1,912 screened studies, 10 were included in our final sample (N = 208 independent participants in experimental and N = 81 in the control groups completing the primary endpoint). We compared the clinical efficacy across studies, and evaluated their experimental designs and reporting quality. In most studies, patients showed improved scores in different cognitive tests. However, data from randomized controlled trials remains scarce, and clinical evidence based on standardized metrics is still inconclusive. In light of recent meta-research developments in the neurofeedback field and beyond, quality and reporting practices of individual studies are reviewed. We conclude with recommendations on best practices for future studies that investigate the effects of neurofeedback training in dementia and cognitive impairment.

Sounds in nursing homes and their effect on health in dementia: a systematic review

OBJECTIVES

Nursing home residents with dementia are sensitive to detrimental auditory environments. This paper presents the first literature review of empirical research investigating (1) the (perceived) intensity and sources of sounds in nursing homes, and (2) the influence of sounds on health of residents with dementia and staff.

DESIGN

A systematic review was conducted in PubMed, Web of Science and Scopus. Study quality was assessed with the Mixed Methods Appraisal Tool. We used a narrative approach to present the results.

RESULTS

We included 35 studies. Nine studies investigated sound intensity and reported high noise intensity with an average of 55-68 dB(A) (during daytime). In four studies about sound sources, human voices and electronic devices were the most dominant sources. Five cross-sectional studies focused on music interventions and reported positives effects on agitated behaviors. Four randomized controlled trials tested noise reduction as part of an intervention. In two studies, high-intensity sounds were associated with decreased nighttime sleep and increased agitation. The third study found an association between music and less agitation compared to other stimuli. The fourth study did not find an effect of noise on agitation. Two studies reported that a noisy environment had negative effects on staff.

CONCLUSIONS

The need for appropriate auditory environments that are responsive to residents' cognitive abilities and functioning is not yet recognized widely. Future research needs to place greater emphasis on intervention-based and longitudinal study design.

"Recovering With Nature": A Review of Ecotherapy and Implications for the COVID-19 Pandemic

Connection with nature has been considered beneficial for psychological well-being since times of evolution. Differences in Indian and Western thoughts have viewed natural elements in different lights, varying between eco-centrism to anthropocentrism. The intrusion of technology and digitalized lives as a result of globalization has decreased connectedness with nature. Ecotherapy is a novel form of psychotherapeutic technique based on explicit environmental or ecological interventions. Social and therapeutic horticulture, animal-assisted interventions, care farming, green exercise, environmental conservation and wilderness therapy are some of the ecosystem-based approaches used in mental health. Based on the principles of positive and client-centered psychology, ecotherapy-related techniques have been shown to be effective in medical disorders like hypertension, obesity, post-surgical recovery and psychosocial conditions like depression, stress reduction, post-traumatic stress disorder (PTSD), attention deficit hyperkinetic disorder (ADHD) and adjustment disorders. The principles of ecotherapy have been integrated into other psychotherapeutic techniques for better efficacy. This review attempts provides an overview of techniques, applications and challenges related to ecotherapy in psychology. The implications of its use during the ongoing Coronavirus 2019 (COVID-19) crisis, social isolation and consequent psychosocial aftermath are also discussed.

Implementation effectiveness of psychosocial and environmental care practices in assisted living

Psychosocial and environmental care practices are recommended to address behavioral expressions in persons with dementia, but their use has been limited partly because guidance is lacking regarding implementation. In response, we developed a simple "how-to" guide of evidence-based protocols for aromatherapy, natural light, familiar music, and robotic pets; trained staff in four assisted living (AL) communities to use the practices; provided materials; met with them regularly; and evaluated fidelity, facilitators and barriers to implementation, and staff knowledge, attitudes, and self-efficacy. After two months, staff reported more familiarity, confidence, and use; barriers such as difficulty locating supplies and task-focused staff with limited time; and staff "champion" facilitators. Notable differences were identified across communities, suggesting that just as care to individuals must be person-centered, practices embraced by communities must fit that community. Through strategic adoption, successful implementation is possible. The "how-to" guide is appropriate for AL, nursing homes, and persons' own homes.

Impacts of large-scale interior murals on hospital employees: a pharmacy department case study

Purpose

Trending in modern interior design frameworks is an integration of real and simulated (i.e. photographs, murals) elements of nature into buildings, and a number of interdisciplinary studies concern the effects of nature on various aspects of human functioning. The purpose of this paper is to measure employees’ self-reported levels of affective organizational commitment (AOC), perceived productivity, well-being, attention restoration and satisfaction at work to explore how each mural is conceptualized and to make recommendations to hospital administrators and facilities managers as they make decisions concerning mural design and placement. One hospital had a biophilic mural and the other had a bold abstract mural.

Design/methodology/approach

The research was carried out using post-occupancy evaluation and mixed-methods survey design.

Findings

Employees in both hospitals disagreed that their organizational commitment (OC), perceived productivity or well-being at work had improved since the new murals had been installed. Responses from both hospitals were also low concerning perceptions of attention restoration. Indeed, no significant differences between hospitals were found. Correlations among scales were found within hospitals that support published studies. More correlations occurred at the hospital where employees viewed the biophilic mural (e.g. between OC and perceived productivity, and between satisfaction with the physical environment and perceived productivity). At both sites, satisfaction with the physical environment correlated with OC.

Originality/value

The authors expected that those working within view of the biophilic mural would report stronger ratings of AOC, perceived productivity, well-being, attention restoration and satisfaction with the workplace than employees with a view of the abstract scene. No differences between groups were found; responses to psychosocial scale items asking about whether attitudes had improved after the retrofit were low or neutral for employees in either hospital. However, more correlations between scales that support existing literature were revealed for those working near the biophilic mural. Thus, the authors recommend architectural programming before a design change to gather insight on occupants’ preferences at work.

The Impact of Green Space on Violent Crime in Urban Environments: An Evidence Synthesis

Can the presence of green space in urban environments reduce the frequency of violent crime? To ascertain the evidence on this topic, we conducted an in-depth literature review using the PRISMA checklist. The search parameters included US articles written in English and published since 2000. More than 30,000 potential paper titles were identified and ultimately, 45 papers were selected for inclusion. Green spaces typically comprised tree cover, parks and ground cover. Criminal behaviors typically included murder, assault, and theft. The majority of the research reviewed involved quantitative methods (e.g., comparison of green space area to crime data). We extracted multiple mechanisms from the literature that may account for the impact of green space on crime including social interaction and recreation, community perception, biophilic stress reduction, climate modulation, and spaces expressing territorial definition. Recommendations are made for future research, such as meta-analysis of existing data and the development of grounded theory through qualitative data-gathering methods. By providing evidence that access to nature has a mitigating impact on violence in urban settings, city governments and communities are empowered to support these interventions.

Designing Urban Green Blue Infrastructure for Mental Health and Elderly Wellbeing

The main objective of this essay is to illustrate the state-of-the-art on ‘mental health-sensitive’ open space design in the built environment. Urban Green Blue Infrastructure can contribute to urbanites’ mental health and wellbeing as well as healthy aging, while providing co-benefits balancing the negative impacts of climate change, through the provision of integrated ecosystem services. There are a number of ways that exposure to and affiliation with Nature have shown to support mental health, but we are still missing the necessary evidence of the actual benefits achieved, as well as the key performance indicators and metrics to monitor and adapt our open space to the growing urban challenges. After introducing the key concepts of degenerative mental disorders as they are growing in the urban environment, and the emerging green blue infrastructure design approach, the authors present international case studies describing how evidence-based design and Nature-based Solutions have been found to be beneficial, especially to those diagnosed with mental disorders. Subsequently, in a comparative critical analysis, the authors look closer at a number of design solutions capable, at different scales, to support healthy aging through exposure to, and affiliation with, biodiversity.

Impact of Multisensory Environments on Behavior for People With Dementia: A Systematic Literature Review

Purpose of the Study

Behavioral and psychological symptoms of dementia (BPSD) affect quality of life for people with dementia. Nonpharmacological interventions are the preferred first line of treatment, and it is theorized that BPSD are directly influenced by sensory imbalance and improved by sensory equilibrium. The purpose of this article is to investigate the evidence regarding the use of multisensory environments (MSEs) as treatment for BPSD.

Design and Methods

A systematic literature review was performed using the PICO framework within PsycINFO, Web of Science, ERIC, PubMED, and Cinahl databases, as well as additional hand-searched documents. Included articles were published during 1990 to 2015 and report empirical studies of MSE BPSD interventions that include furniture, fixtures, and equipment to provide visual, auditory, tactile, and olfactory stimulation. Desired elements include ergonomic vibroacoustic furniture, bubble tubes, color-changing lights, and fiber optics.

Results

Twelve articles met the inclusion criteria for review. Evidence supports the positive impact of sensory stimulation as a nonpharmacological behavioral treatment for dementia. Many studies investigated both behavior and mood, and several investigated biomedical parameters including heart rate and cognition. Significant differences were not found in the between-group studies when MSE was compared with other one-to-one interventions. Results on long-term effects were mixed. Variations can be seen in terms of research methods, types of environmental interventions, duration, and specific characteristics of participants, thus confounding the reliability of findings.

Implications

Key findings and directions for future research are discussed including primary outcomes, study design, environmental intervention types, and relevant assessment tools.

Ecotherapy - A Forgotten Ecosystem Service: A Review

Natural ecosystems provide important services upon which humans depend. Unfortunately, some people tend to believe that these services are provided by nature for free; therefore, the services have little or no value. One nearly forgotten ecosystem service is ecotherapy – the ability of interaction with nature to enhance healing and growth. While we do not pay for this service, its loss can result in a cost to humans resulting in slower recovery times, greater distress and reduced well-being. Losses in these images of nature can diminish our basic happiness. Little is understood or, at least, appreciated concerning the potential ecotherapy benefits of the natural environment and its ecosystem services. The complex and interactive relationship of ecosystems, their services and human well-being is poorly acknowledged in the broad social, philosophical, psychological and economic well-being literature. In this article, we examine the role of nature and its ecosystem services in ecotherapy and its associated enhancement of recovery from physical and mental illness through a review of studies evaluating this ecosystem service-recovery connection.

Impact of the design of the built environment on people with dementia: an evidence-based review

OBJECTIVE

In this review the impact of the design of the built environment on people with dementia in long-term care settings is systematically analyzed and summarized. Architects and designers will be provided with credible evidence on which they can confidently base their design decisions. Researchers will be able to determine which environmental aspects have been well investigated and where there are gaps in the current state of the research.

BACKGROUND

A great number of studies have established a relationship between the design of the physical environment of long-term care settings and outcomes of people with dementia. However, the methods employed are heterogeneous and the results are often conflicting. Consequently, the process of integrating the best evidence available into architectural designs may be hindered.

METHODS

A systematic literature search was conducted reviewing studies that meet certain inclusion criteria. Using an evidence-based approach, the methodical quality of the studies was rated.

RESULTS

One hundred sixty-nine studies were found. They were thematically summarized into four main categories: basic design decisions, environmental attributes, ambience, and environmental information. The effectiveness of the interventions on the behavior, cognition, function, well being, social abilities, orientation, and care outcomes on people with dementia was illustrated by matrices.

CONCLUSIONS

Results of this review indicate that, with the exception of cognition, specific design interventions are beneficial to the outcomes of people with dementia. Overall, the field of environmental design for people with dementia is well researched in many aspects and only few gaps in knowledge were identified.

Evidence-Based Nonpharmacological Practices to Address Behavioral and Psychological Symptoms of Dementia

Background and Objectives

To draw from systematic and other literature reviews to identify, describe, and critique nonpharmacological practices to address behavioral and psychological symptoms of dementia (BPSDs) and provide evidence-based recommendations for dementia care especially useful for potential adopters.

Research Design and Methods

A search of systematic and other literature reviews published from January 2010 through January 2017. Nonpharmacological practices were summarized to describe the overall conceptual basis related to effectiveness, the practice itself, and the size and main conclusions of the evidence base. Each practice was also critically reviewed to determine acceptability, harmful effects, elements of effectiveness, and level of investment required, based on time needed for training/implementation, specialized care provider requirements, and equipment/capital requirements.

Results

Nonpharmacological practices to address BPSDs include sensory practices (aromatherapy, massage, multi-sensory stimulation, bright light therapy), psychosocial practices (validation therapy, reminiscence therapy, music therapy, pet therapy, meaningful activities), and structured care protocols (bathing, mouth care). Most practices are acceptable, have no harmful effects, and require minimal to moderate investment.

Discussion and Implications

Nonpharmacological practices are person-centered, and their selection can be informed by considering the cause and meaning of the individual's behavioral and psychological symptoms. Family caregivers and paid care providers can implement evidence-based practices in home or residential care settings, although some practices require the development of more specific protocols if they are to become widely used in an efficacious manner.

Novel Cortical Thickness Pattern for Accurate Detection of Alzheimer's Disease

Brain network occupies an important position in representing abnormalities in Alzheimer's disease (AD) and mild cognitive impairment (MCI). Currently, most studies only focused on morphological features of regions of interest without exploring the interregional alterations. In order to investigate the potential discriminative power of a morphological network in AD diagnosis and to provide supportive evidence on the feasibility of an individual structural network study, we propose a novel approach of extracting the correlative features from magnetic resonance imaging, which consists of a two-step approach for constructing an individual thickness network with low computational complexity. Firstly, multi-distance combination is utilized for accurate evaluation of between-region dissimilarity; and then the dissimilarity is transformed to connectivity via calculation of correlation function. An evaluation of the proposed approach has been conducted with 189 normal controls, 198 MCI subjects, and 163 AD patients using machine learning techniques. Results show that the observed correlative feature suggests significant promotion in classification performance compared with cortical thickness, with accuracy of 89.88% and area of 0.9588 under receiver operating characteristic curve. We further improved the performance by integrating both thickness and apolipoprotein E ɛ4 allele information with correlative features. New achieved accuracies are 92.11% and 79.37% in separating AD from normal controls and AD converters from non-converters, respectively. Differences between using diverse distance measurements and various correlation transformation functions are also discussed to explore an optimal way for network establishment.

New Evidence on the Green House Model of Nursing Home Care: Synthesis of Findings and Implications for Policy, Practice, and Research

OBJECTIVE

To synthesize new findings from the THRIVE Research Collaborative (The Research Initiative Valuing Eldercare) related to the Green House (GH) model of nursing home care and broadly consider their implications.

DATA SOURCES

Interviews and observations conducted in GH and comparison homes, Minimum Data Set (MDS) assessments, Medicare data, and Online Survey, Certification and Reporting data.

STUDY DESIGN

Critical integration and interpretation of findings based on primary data collected 2011-2014 in 28 GH homes (from 16 organizations), and 15 comparison nursing home units (from 8 organizations); and secondary data derived from 2005 to 2010 for 72 GH homes (from 15 organizations) and 223 comparison homes.

PRINCIPAL FINDINGS

Implementation of the GH model is inconsistent, sometimes differing from design. Among residents of GH homes, adoption lowers hospital readmissions, three MDS measures of poor quality, and Part A/hospice Medicare expenditures. Some evidence suggests the model is associated with lower direct care staff turnover.

CONCLUSIONS

Recommendations relate to assessing fidelity, monitoring quality, capitalizing opportunities to improve care, incorporating evidence-based practices, including primary care providers, supporting high-performance workforce practices, aligning Medicare financial incentives, promoting equity, informing broad culture change, and conducting future research.

Dementia prevalence and care in assisted living

Assisted living residences have become prominent sites of long-term residential care for older adults with dementia. Estimates derived from national data indicate that seven out of ten residents in these residences have some form of cognitive impairment, with 29 percent having mild impairment, 23 percent moderate impairment, and 19 percent severe impairment. More than one-third of residents display behavioral symptoms, and of these, 57 percent have a medication prescribed for their symptoms. Only a minority of cognitively impaired residents reside in a dementia special care unit, where admission and discharge policies are more supportive of their needs. Policy-relevant recommendations from our study include the need to examine the use of psychotropic medications and cultures related to prescribing, better train assisted living staff to handle medications and provide nonpharmacological treatments, use best practices in caring for people with dementia, and promote consumer education regarding policies and practices in assisted living.

The Impact of Simulated Nature on Patient Outcomes

Objective:

To examine whether incorporation of simulated nature, in the form of ceiling mounted photographic sky compositions, influences patient outcomes.

Background:

Previous studies have shown that most forms of nature exposure have a positive influence on patients. However, earlier studies have mostly focused on wall-hung nature representations. The emergence of simulated nature products has raised the question regarding the effects of the new product on patient outcomes.

Methods:

A between-subject experimental design was adopted, where outcomes from five inpatient rooms with sky composition ceiling fixture were compared to corresponding outcomes in five identical rooms without the intervention. Data were collected from a total of 181 subjects on 11 outcomes. Independent sample tests were performed to identify differences in mean outcomes.

Result:

Significant positive outcomes were observed in environmental satisfaction and diastolic blood pressure (BP). Environmental satisfaction in the experimental group was 12.4% higher than the control group. Direction of association for diastolic BP, nausea/indigestion medication, acute stress, anxiety, pain, and environmental satisfaction were consistent with a priori hypothesis. A post hoc exploratory assessment involving patients who did not self-request additional pain and sleep medication demonstrated confirmatory directions for all outcomes except Systolic BP, and statistically significant outcomes for Acute Stress and Anxiety—Acute Stress and Anxiety levels of the experimental group subjects was 53.4% and 34.79% lower, respectively, than that of the control group subjects.

Conclusion:

Salutogenic benefits of photographic sky compositions render them better than traditional ceiling tiles and offer an alternative to other nature interventions.

A best-evidence review of intervention studies for minimizing resistance-to-care behaviours for older adults with dementia in nursing homes

AIM

To conduct a best-evidence review of non-pharmacological interventions for resistance-to-care behaviours of nursing home residents with dementia in a personal-care context.

BACKGROUND

Resistance to care is a major source of staff burnout in nursing homes and it is also a safety issue for the staff.

DESIGN

Best-evidence review.

DATA SOURCES

We searched for non-pharmacological intervention studies published from 1990-2012, written in English.

REVIEW METHODS

The search identified 19 intervention studies that examined the effects of interventions to reduce the resistance-to-care behaviours of nursing home residents with dementia in a personal-care context. These 19 papers met the quality assessment requirements of the critical appraisal criteria for experimental studies, which were published by the Joanna Briggs Institute.

RESULTS

Only three studies were RCTs and the rest were quasi-experimental. The sample size ranged from 7-127. Nine music interventions, such as pre-recorded music played to a group or playing a resident's preferred music, during his or her personal care, resulted in significant reductions in resistance-to-care behaviours. Resistance-to-care behaviours also were significantly reduced in three of four bathing interventions that focused on person-centred care. In the ability-focused interventions, only two out of five studies reported significant reductions in resistance-to-care behaviours.

CONCLUSION

Non-pharmacological interventions are options to consider to reduce resistance-to-care behaviours in older people with dementia, even though the evidence level is low, given the lack of alternatives. More randomized controlled trials are recommended to confirm the effects of non-pharmacological interventions during personal care.

Measurement of aggressive behaviors in dementia: comparison of the physical aggression subscales of the Cohen-Mansfield Agitation Inventory and the Ryden Aggression Scale

One of the central issues in the development of research-based interventions for aggressive behavior (AB) in late-stage dementia is the provision of precise measurement of the major dependent variable, in this case, AB levels. To advance the nursing goal of evidence-based practice, this article presents the characteristics of two research instruments: the Cohen-Mansfield Agitation Inventory (CMAI) aggressive behavior subscale (CMAI-ABS) and the Ryden Aggression Scale (RAS) physically aggressive behavior subscale (RAS-PABS). A total of 282 shower bath events (which are most associated with AB) were observed for 107 nursing home residents with dementia in nine randomly selected nursing homes. Then, we compared the psychometric properties of the CMAI-ABS and the RAS-PABS. Moderate to substantial agreements between the two instruments were identified using Cohen's Kappa. A similar percentage of AB was found on both subscales. Similar items on both subscales, such as hitting and pushing, were moderately correlated. Overall, the study results support that the CMAI-ABS and RAS-PABS measure a single but multifaceted construct-physically aggressive behavior in dementia.

Strategies to promote safe medication administration in assisted living settings

Assisted living (AL) provides lower cost, less institutional environments than skilled nursing facilities, yet less professional oversight, despite the high prevalence of chronic conditions among residents. Unlicensed staff administer large quantities of medications daily, and medication management is one of the three top quality issues in AL, with error rates ranging from 10% to 40%. This qualitative study described AL provider views on medication safety and strategies used to promote safety in medication administration. The sample included 96 participants representing all parties involved in medication administration (i.e., medication aides, administrators, RNs, consulting pharmacists, primary care providers) in 12 AL settings in three states. Core themes were the importance of medication safety, unique contextual factors in AL, and strategies used to promote medication safety. This study has implications for research on interventions to improve medication safety at the individual, facility, and policy levels.

Comparing responses to horticultural-based and traditional activities in dementia care programs

Engaging persons with dementia in meaningful activities supports well-being; however, care staff are challenged to implement age- and ability-appropriate activities in a group setting. We compared a randomly assigned treatment group, who received horticultural therapy-based (HT-based) programming to a comparison group, who engaged in traditional activities (TA) programming, on engagement and affect. Horticultural therapy-based programming was implemented twice weekly at 4 treatment sites for 6 weeks, while regular TA were observed at comparison sites. Results revealed no differences between groups on affective domains. Levels of adaptive behavior differed between the groups, with the treatment group demonstrating higher levels of active, passive, and other engagement and the comparison group demonstrating higher levels of self-engagement. Our results highlight the value of HT-based programs and the importance of simultaneously capturing participants' affective and behavioral responses. Theoretical and practical considerations about the facilitation of and context in which the programming occurs are discussed.

Wandering and the physical environment

BACKGROUND/RATIONALE

Guided by the need-driven dementia-compromised behavior (NDB) model, this study examined influences of the physical environment on wandering behavior.

METHODS

Using a descriptive, cross-sectional design, 122 wanderers from 28 long-term care (LTC) facilities were videotaped 10 to 12 times; data on wandering, light, sound, temperature and humidity levels, location, ambiance, and crowding were obtained. Associations between environmental variables and wandering were evaluated with chi-square and t tests; the model was evaluated using logistic regression.

RESULTS

In all, 80% of wandering occurred in the resident's own room, dayrooms, hallways, or dining rooms. When observed in other residents' rooms, hallways, shower/baths, or off-unit locations, wanderers were likely (60%-92% of observations) to wander. The data were a good fit to the model overall (LR [logistic regression] chi(2) (5) = 50.38, P < .0001) and by wandering type.

CONCLUSIONS

Location, light, sound, proximity of others, and ambiance are associated with wandering and may serve to inform environmental designs and care practices.

Management of behavioral problems in Alzheimer's disease

Alzheimer's disease (AD) is a complex progressive brain degenerative disorder that has effects on multiple cerebral systems. In addition to cognitive and functional decline, diverse behavioral changes manifest with increasing severity over time, presenting significant management challenges for caregivers and health care professionals. Almost all patients with AD are affected by neuropsychiatric symptoms at some point during their illness; in some cases, symptoms occur prior to diagnosis of the dementia syndrome. Further, behavioral factors have been identified, which may have their origins in particular neurobiological processes, and respond to particular management strategies. Improved clarification of causes, triggers, and presentation of neuropsychiatric symptoms will guide both research and clinical decision-making. Measurement of neuropsychiatric symptoms in AD is most commonly by means of the Neuropsychiatric Inventory; its utility and future development are discussed, as are the limitations and difficulties encountered when quantifying behavioral responses in clinical trials. Evidence from clinical trials of both non-pharmacological and pharmacological treatments, and from neurobiological studies, provides a range of management options that can be tailored to individual needs. We suggest that non-pharmacological interventions (including psychosocial/psychological counseling, interpersonal management and environmental management) should be attempted first, followed by the least harmful medication for the shortest time possible. Pharmacological treatment options, such as antipsychotics, antidepressants, anticonvulsants, cholinesterase inhibitors and memantine, need careful consideration of the benefits and limitations of each drug class.

Personalized dementia care: proven effectiveness of psychosocial interventions in subgroups

Many psychosocial intervention studies report effects in subgroups of people with dementia. Insight into the characteristics of these subgroups is important for care practice. This study reviews personal characteristics of people with dementia (living in the community or in an institution) that are related to positive outcomes of psychosocial interventions. Electronic databases and key articles were searched for effect studies published between January 1990 and February 2008. Outcome measures were clustered into categories such as cognitive functioning, behavioural functioning and mental health. Seventy-one studies showed positive outcomes on psychosocial interventions, such as decreased depression and less behavioural problems, related to personal characteristics of people with dementia, such as gender, type or severity of dementia, presence of behavioural or mental health problems, and living situation. For people with dementia living in the community positive effects were most frequently found in the persons with mild to severe dementia not otherwise specified and with mild to moderate Alzheimer's Disease. For people with dementia living in an institution positive effects were found most frequently in the subgroups moderate to severe dementia, severe to very severe dementia and in the subgroup with behavioural problems. This study provides a unique overview of characteristics that are related to effective intervention outcomes. It also suggests that more research will lead to a better understanding of which care and welfare interventions are effective for specific subgroups of people with dementia.

The importance of getting back to nature for people with dementia

As people age, the ability to interact with the outdoors may lessen. Frailty and mobility problems create barriers to engaging in outdoor activities or even experiencing the outdoors. The barriers are greater for people with dementia. As the disease worsens to the point of institutionalization, access to the outdoors may be completely barred and opportunities relinquished to the determination of facility personnel. This article will review current literature and some older seminal works on nature and nature-based stimuli for people with dementia, especially those living in nursing homes.

Aggression in persons with dementia: use of nursing theory to guide clinical practice

With approximately four million people in the United States today diagnosed with dementia, one of the most devastating problems faced by caregivers and patients is dealing with aggressive behavior. Aggression occurs in half of persons diagnosed with dementia and is associated with more rapid cognitive decline, increased risk of abuse, and caregiver burden. This paper uses the Need-driven Dementia-compromised Behavior (NDB) model to explain aggression and discusses therapeutic approaches to care that combines non-pharmacological and pharmacological interventions targeting both the management of aggression crisis and preventing its future recurrence. A clinical algorithm guided by the NBD model is provided for practitioners.

A Review of the Research Literature on Evidence-Based Healthcare Design

Objective:

This report surveys and evaluates the scientific research on evidence-based healthcare design and extracts its implications for designing better and safer hospitals.

Background:

It builds on a literature review conducted by researchers in 2004.

Methods:

Research teams conducted a new and more exhaustive search for rigorous empirical studies that link the design of hospital physical environments with healthcare outcomes. The review followed a two-step process, including an extensive search for existing literature and a screening of each identified study for the relevance and quality of evidence.

Results:

This review found a growing body of rigorous studies to guide healthcare design, especially with respect to reducing the frequency of hospital-acquired infections. Results are organized according to three general types of outcomes: patient safety, other patient outcomes, and staff outcomes. The findings further support the importance of improving outcomes for a range of design characteristics or interventions, including single-bed rooms rather than multibed rooms, effective ventilation systems, a good acoustic environment, nature distractions and daylight, appropriate lighting, better ergonomic design, acuity-adaptable rooms, and improved floor layouts and work settings. Directions for future research are also identified.

Conclusions:

The state of knowledge of evidence-based healthcare design has grown rapidly in recent years. The evidence indicates that well-designed physical settings play an important role in making hospitals safer and more healing for patients, and better places for staff to work.

Bathing: A framework for intervention focusing on psychosocial, architectural and human factors considerations

The process of bathing is usually pleasurable and relaxing for most persons and, although it serves hygienic needs, it is often individualized to a person's preferences in order to enhance the pleasurable experience. In contrast, the bathing process for elderly people suffering from dementia is often a traumatic experience for both the persons with dementia and their caregivers. Agitated behaviors are manifested more often during bathing than at other times. Factors influencing the experience of the bathing process and resulting in agitated behaviors can be categorized into four broad groups: the needs of the person with dementia, the needs of the caregiver, the physical environment in which bathing takes place and institutional factors. A number of approaches have been employed to treat agitated behaviors during bathing; however, a comprehensive approach addressing all of the above factors has not been developed. This paper presents preliminary findings on the effectiveness of the Treatment Routes for Exploring Agitation (TREA) approach for non-pharmacological interventions within a larger framework of human factors, addressing the needs of residents and staff members, environmental factors as well as human factors analysis to improve the process of bathing. A case study demonstrates the efficacy of this approach in reducing agitated behaviors during bathing.

Preserved implicit memory in dementia: a potential model for care

A growing body of evidence supports the presence of a preserved implicit memory (PIM) system for persons with Alzheimer's disease (AD). This article describes a new approach to dementia care, the PIM model, which translates evidence from implicit memory research into a practice model of dementia care. The PIM model predicts that function can be sustained longer for persons with AD through interventions and environments that activate an individual's PIM. Activation of PIM can occur with perceptual priming of familiar objects and reinforcement of learned motor skill memories within tasks. This practice model provides a new framework for planning and implementing dementia care that may preserve function for persons with Alzheimer's dementia.

Behavioural symptoms of dementia in residential settings: a selective review of non-pharmacological interventions

For people with dementia living in residential settings, behaviours such as aggression, screaming, restlessness, agitation and wandering are a frequent reason for referral to specialist mental health services for older people. Psychosocial models of dementia have grown in prominence and non-pharmacological interventions have been recommended in professional and government policy statements, either as a first line of treatment or alongside medication. Studies of their effectiveness have been criticised for being poorly controlled, focusing on milder behaviour problems and for requiring a disproportionate use of resources. The recent ruling that risperidone and olanzepine should not be used to control behavioural symptoms in dementia makes it timely to review the evidence for alternative treatments. The current review is a selective one of different types of studies including studies of staff training and liaison interventions, studies of a range of different therapeutic interventions and individualized interventions within a single-case methodology. It is argued that different types of research methodology are appropriate for different studies and that there is still too little evidence to provide firm guidelines. In conclusion, a structured decision-making process for selection of interventions is proposed, in which the limited available evidence can be drawn together to provide a basis for targeting clinical resources while the research evidence is strengthened.

Effect of the BACE intervention on agitation of people with dementia

PURPOSE

This study tests the effectiveness of the theoretically driven BACE (i.e., Balancing Arousal Controls Excesses) intervention in decreasing agitation in residents of long-term care with moderate or severe dementia.

DESIGN AND METHODS

A pretest-posttest double-blinded experimental design with random assignment was used with a sample of 78 participants. The BACE intervention controls the daily activity schedule so that there is a balance between a person's high-arousal and low-arousal states. The outcome measure was observed agitation.

RESULTS

When time spent in arousal imbalance at pretest was controlled for, a repeated measures analysis of covariance revealed a statistically significant Group x Time interaction, F(1, 69) = 4.26, p =.043, with a partial eta(2) =.06. The average change in agitation for the treatment group was a decrease of 8.43 points (SD = 12.01) from pretest to posttest, an effect size of.7.

IMPLICATIONS

The results of this study support the theory that balancing arousal states by using an individualized approach is effective in decreasing agitation levels of people with dementia.

A randomized, controlled, clinical trial of activity therapy for apathy in patients with dementia residing in long-term care

BACKGROUND

Apathy is a common symptom in patients with dementia and has adverse consequences for patients and caregivers. Most treatments for apathy, particularly non-pharmacologic interventions, have not been evaluated in controlled trials.

OBJECTIVES

This study evaluated the efficacy of a kit-based activity intervention, compared to a time and attention control (one-on-one meetings with an activity therapist) in reducing apathy and improving quality of life in 37 patients with dementia.

METHODS

The design was a randomized, controlled, partially masked clinical trial. All outcome measures were administered at baseline and follow-up. The primary outcome measure was the apathy score of the Neuropsychiatric Inventory (NPI). Other outcome measures were the NPI total score, the Alzheimer Disease Related Quality of Life scale(ADQRL), and the Copper Ridge Activity Index (CRAI).

RESULTS

There was a significant reduction in NPI apathy scores in both treatment groups. The only significant difference between the two treatment groups was a modest advantage for the control intervention on the CRAI cueing subscale (p = 0.027), but not on the other CRAI subscales. There was also a greater within group improvement in quality of life ratings in the control intervention (p=0.03).

CONCLUSIONS

Despite the substantial improvement in apathy scores during the course of the study, there was no clear advantage to the reminiscence-based intervention over the time and attention, one-on-one control intervention. More research is needed to develop specific behavioral interventions for apathy in patients with dementia.

The relationship between self-destructive behaviour and nursing home environment

The aim of this study was to explore the relationship between self-destructive behaviour and nursing home environment. We performed a cross-sectional study comprising 647 residents in 11 nursing homes in Sydney, Australia using the Harmful Behaviours Scale (HBS), Abbreviated Mental Test Scale and the Resident Classification Index. The Directors of Nursing completed a questionnaire that rated physical design, staff and resident characteristics and demographics were obtained from nursing home records. On regression analysis a greater number of design features for frail and residents with dementia in general, and increased security measures were associated with greater HBS total score and risk-taking and passive self-harm subscales. A residential environment in which the residents were more functionally dependent and more likely to be in a shared room, managerial policies less geared towards managing difficult behaviour and less staff availability and training were associated with the 'uncooperativeness' factor. There were no significant predictors of the other two factors. The relationship between nursing home environment and self-destructive behaviours and the environment is complex and there needs to be an individualized approach to placement.

Assessment and treatment of nursing home residents with depression or behavioral symptoms associated with dementia: a review of the literature

Depression and the behavioral symptoms associated with dementia remain two of the most significant mental health issues for nursing home residents. The extensive literature on these conditions in nursing homes was reviewed to provide an expert panel with an evidence base for making recommendations on the assessment and treatment of these problems. Numerous assessment instruments have been validated for depression and for behavioral symptoms. The Minimum Data Set, as routinely collected, appears to be of limited utility as a screening instrument for depression but is useful for assessing some behavioral symptoms. Laboratory evaluations are often recommended, but no systematic study of the outcomes of these evaluations could be found. Studies of nonpharmacological interventions out-number those of pharmacological interventions, and randomized, controlled trials document the efficacy of many interventions. Antidepressants are effective for major depression, but data for minor depressive syndromes are limited. Recreational activities are effective for major and minor depression categories. Neither pharmacological nor nonpharmacological interventions totally eliminate behavioral symptoms, but both types of interventions decrease the severity of symptoms. In the absence of comparison studies, it is unclear whether one approach is more effective than another. Despite federal regulations limiting their use, antipsychotics are effective and remain the most studied medications for treating behavioral symptoms, whereas benzodiazepines and antidepressants have less support. Structured activities are effective, but training interventions for behavioral symptoms had limited results. There are sufficient data to formulate an evidenced-based approach to treatment of depression and behavioral symptoms, but more research is needed to prioritize treatments.

Deriving interventions from the NDB model. Using natural environment and implicit memory theories

By drawing on theoretical propositions developed outside nursing, and by modifying and synthesizing these with nursing experiential data, useful statements for practice may be developed for further examination. Because practice theory for the care of patients with dementia is not well-developed or well-examined yet, the process described here to develop meaningful interventions for practice should be further explored and evaluated.

Effects of behavioral interventions on disruptive behavior and affect in demented nursing home residents

BACKGROUND

Disruptive behaviors are prevalent in nursing home residents with dementia and often have negative consequences for the resident, caregiver, and others in the environment. Behavioral interventions might ameliorate them and have a positive effect on residents' mood (affect).

OBJECTIVES

This study tested two interventions-an activities of daily living and a psychosocial activity intervention-and a combination of the two to determine their efficacy in reducing disruptive behaviors and improving affect in nursing home residents with dementia.

METHODS

The study had three treatment groups (activities of daily living, psychosocial activity, and a combination) and two control groups (placebo and no intervention). Nursing assistants hired specifically for this study enacted the interventions under the direction of a master's prepared gerontological clinical nurse specialist. Nursing assistants employed at the nursing homes recorded the occurrence of disruptive behaviors. Raters analyzed videotapes filmed during the study to determine the interventions' influence on affect.

RESULTS

Findings indicated significantly more positive affect but not reduced disruptive behaviors in treatment groups compared to control groups.

CONCLUSIONS

The treatments did not specifically address the factors that may have been triggering disruptive behaviors. Interventions much more precisely designed than those employed in this study require development to quell disruptive behaviors. Nontargeted interventions might increase positive affect. Treatments that produce even a brief improvement in affect indicate improved quality of mental health as mandated by federal law.

The agitation-activity interface of people with dementia in long-term care

The purpose of this study was to examine agitated behaviors of people with dementia relative to time and activity variables. This descriptive study involved a sample of 420 units of 30-minute time periods collected in a long-term care setting. The highest agitation scores occurred during the evening (F = 3.93, p = 0.009). Agitation scores were significantly higher when the same level of activity was sustained for 1.5 hours or longer (p = 0.000). This study suggests that future examination is needed of an intervention to control activity schedules so that there is a balance between sensory-stimulating and sensory-calming activities.

Assessment and management of behavioral disturbances in nursing home patients with dementia

Behavioral disturbances among nursing home patients with dementia are common and substantially affect patients and caregivers. Assessing the environmental, medical, and psychiatric causes of problematic behaviors and implementing a plan of behavioral, medical, and psychiatric management can reduce difficult target behaviors. This article presents a multifaceted approach to assessing patients with dementia who have behavioral problems, reviews medical and pharmacological management of these problems, and presents a multidisciplinary approach to developing treatment plans aimed at reducing such behaviors among nursing home patients with dementia.
