The Assessment of Long-Term Care Environments for Wayfinding Design

OBJECTIVES

The purpose of this article is to compare three different methods to assess the complexity of a long-term care (LTC) environment for wayfinding before and after an environmental design intervention. The methods include space syntax (SS), the Wayfinding Checklist (WC), and the Tool to Assess Wayfinding Complexity (TAWC).

BACKGROUND

Wayfinding is important to maintain older adults' independent functioning. The design of environments can impact wayfinding ability by providing support; this can be via building structure or by environmental design features such as signage and landmarks. Few methods or tools have been scientifically validated to assess environments for wayfinding complexity. In order to compare environments in terms of complexity and to measure the impact of interventions, valid and reliable tools are necessary.

METHODS

This article discusses the results of the use of three wayfinding design assessment tools using three routes in one LTC environment. The results of the three tools are discussed.

RESULTS

SS analysis could quantitatively measure the complexity of routes using integration values, which indicates connectedness. The TAWC and the WC were able to measure differences in visual field scores pre- and postenvironmental intervention. There were limitations to each tool: the lack of psychometric properties for the TAWC and the WC, and the lack of ability to measure changes in design features within visual fields with SS.

CONCLUSIONS

Multiple tools to assess environments for wayfinding design may be needed in studies that test environmental interventions. Future research is needed to provide psychometric testing for the tools.

Wandering behavior in children with autism spectrum disorder and other developmental disabilities

PURPOSE OF REVIEW

Approximately one in four children with autism spectrum disorder (ASD) 'elope' or wander away from supervision each year; however, many caregivers do not receive adequate information on how to address wandering behavior. The purpose of this review is to summarize the available research on elopement frequency, wandering patterns, and interventions to provide pediatricians and other childcare professionals with appropriate strategies to address wandering behavior.

RECENT FINDINGS

Despite the high prevalence of wandering by children with ASD or other developmental disabilities, there is relatively limited research in this area. Recent research has identified common patterns and factors associated with risk of elopement and elopement frequency.

SUMMARY

Pediatricians should counsel families on the common issues and intervention strategies related to elopement. By increasing awareness of wandering in children with ASD, caregivers can feel better prepared to make informed decisions regarding their child's wellbeing and safety.

Night-Time Monitoring System (eNightLog) for Elderly Wandering Behavior

Wandering is a common behavioral disorder in the community-dwelling elderly. More than two-thirds of caregivers believe that wandering would cause falls. While physical restraint is a common measure to address wandering, it could trigger challenging behavior in approximately 80% of the elderly with dementia. This study aims to develop a virtual restraint using a night monitoring system (eNightLog) to provide a safe environment for the elderly and mitigate the caregiver burden. The eNightLog system consisted of remote sensors, including a near infra-red 3D time-of-flight sensor and ultrawideband sensors. An alarm system was controlled by customized software and algorithm based on the respiration rate and body posture of the elderly. The performance of the eNightLog system was evaluated in both single and double bed settings by comparing to that of a pressure mat and an infrared fence system, under simulated bed-exiting scenarios. The accuracy and precision for the three systems were 99.0%, 98.8%, 85.9% and 99.2%, 97.8%, 78.6%, respectively. With higher accuracy, precision, and a lower false alarm rate, eNightLog demonstrated its potential as an alternative to physical restraint to remedy the workload of the caregivers and the psychological impact of the elderly.

Wandering Behavior From the Perspectives of Older Adults With Mild to Moderate Dementia in Long-Term Care

Wandering is often described as aimless and disruptive in long-term care (LTC) facilities. Kitwood's Enriched Model of Dementia challenges one to focus on the person, not the behavior. The current exploratory study addressed a gap in knowledge of wandering behavior by gaining the perspectives of older adults with mild to moderate dementia residing in LTC. Walking interviews were conducted with eight older adults. Six themes emerged from their perspectives: Walking as Enjoyable, Walking for Health Benefits, Walking as Purposeful, Walking as a Lifelong Habit, Walking as a Form of Socialization, and Walking to Be With Animals. These results suggest a reconceptualization of wandering behavior from aimless walking and disruption to a purposeful and beneficial activity. [Res Gerontol Nurs. 2019; 12(5):239-247.].

NonPharmacological interventions for managing wandering in the community: A narrative review of the evidence base

Dementia-related wandering is exhibited by as many as 63% of people with dementia living in the community. There is strong evidence that people with dementia who wander are at risk of life-threatening outcomes including injury from falls, exhaustion, weight loss, and becoming lost. Furthermore, carers have reported that fear of a person with dementia becoming lost contributes to them taking extreme measures in an attempt to maintain safety at home and there are few guidelines to direct care practices. Previous literature reviews of interventions to manage wandering have been inconclusive as the quality of research resulted in most studies being excluded. This narrative review aimed to report on the current state of wandering intervention science for people with dementia cared for in the community. An extensive search of articles and grey literature published between January 1999 and November 2017 was conducted and included quantitative studies that reported findings of nonpharmacological interventions for people with dementia living in the community that reported outcome measures of wandering characteristics (e.g., frequent ambulation, pacing, and boundary transgression). Eleven papers met the inclusion criteria, the majority of which were small nonrandomised studies or case studies with interventions that focused on: engaging the person with dementia in an activity, improving safety with environmental modifications, and technology to improve navigation or to monitor movement. While the strength of the evidence was low, the review has identified some promising interventions that carers of people with dementia could trial to reduce risky aspects of wandering, as well as identifying potential directions for future research.

What do we know about technologies for dementia-related wandering? A scoping review: Examen de la portée : Que savons-nous à propos des technologies de gestion de l'errance liée à la démence?

BACKGROUND

Occupational therapists use technologies to manage wandering-related risks to promote safety and independence among individuals with dementia living in the community.

PURPOSE

The purpose of this review was to examine types of technologies used to manage wandering behaviour.

METHOD

Using a modification of Arksey and O'Malley's methodology, we systematically searched peer-reviewed and grey literature on technologies used in home or supportive care environments for persons with dementia at risk for wandering. Data from the studies were analyzed descriptively.

FINDINGS

The literature described 83 technologies. Nineteen devices were clinically tested. Interventions ranged from alarm products to mobile locator devices. Benefits included reductions in risk and caregiver burden.

IMPLICATIONS

Occupational therapy strategies include technologies to enhance function in persons with dementia. Technologies can also reduce risks of wandering and should be affordable. Ethical issues of the use of technology must be addressed. More research is needed to increase levels of evidence.

Who Is Responsible? A Man With Dementia Wanders From Home, Is Hit by a Train, and Dies

The impact of dementia and Alzheimer's disease extends far beyond the healthcare needs of the person with dementia. As the disease progresses, individuals with dementia often require ongoing formal or informal care for their basic daily routine because of behavior changes and continuing loss of cognitive function. Most of the care for people with dementia takes place at home, and the unpaid, informal caregivers are often spouses or other relatives. Providing long-term informal care at home for someone with dementia is psychologically, physically, and financially draining. The tragedy described in this case elucidates the far-reaching societal impact of dementia care and the implicit health policy considerations. In 2007, a 91-year-old Japanese man with dementia was in the care of his wife when he wandered from home, was hit by a train, and died, immediately affecting the Central Japan Railway Company operations and, subsequently, legal practice as well as Japanese elder care policy. The railway sued the man's wife and son for negligence and lost revenue, winning both trials at the local and district courts. This ruling shocked families and caregivers in Japan, where care for elderly parents traditionally falls on the oldest son, and brought attention to the complex issues related to dementia care. A decade later, we revisit this case to provoke a renewed dialogue about the matrix of responsibilities and liabilities associated with caregiving; to illuminate the unmet needs of the person with dementia, as well as his or her informal caregivers; and the financial implications related to long-term care policy. We close with 2 practical suggestions which preserve the dignity of the individual and provide reassurance for caregivers.

Effectiveness of Environment-Based Interventions That Address Behavior, Perception, and Falls in People With Alzheimer's Disease and Related Major Neurocognitive Disorders: A Systematic Review

OBJECTIVE

This systematic review evaluated the effectiveness of environment-based interventions that address behavior, perception, and falls in the home and other settings for people with Alzheimer's disease (AD) and related major neurocognitive disorders (NCDs).

METHOD

Database searches were limited to outcomes studies published in English in peer-reviewed journals between January 2006 and April 2014.

RESULTS

A total of 1,854 articles were initially identified, of which 42 met inclusion criteria.

CONCLUSION

Strong evidence indicates that person-centered approaches can improve behavior. Moderate evidence supports noise regulation, environmental design, unobtrusive visual barriers, and environmental relocation strategies to reduce problematic behaviors. Evidence is insufficient for the effectiveness of mealtime ambient music, bright light, proprioceptive input, wander gardens, optical strategies, and sensory devices in improving behavior or reducing wandering and falls. Although evidence supports many environment-based interventions used by occupational therapy practitioners to address behavior, perception, and falls in people with AD and related major NCDs, more studies are needed.

Wandering behaviour prevents inter and intra oceanic speciation in a coastal pelagic fish

Small pelagic fishes have the ability to disperse over long distances and may present complex evolutionary histories. Here, Old World Anchovies (OWA) were used as a model system to understand genetic patterns and connectivity of fish between the Atlantic and Pacific basins. We surveyed 16 locations worldwide using mtDNA and 8 microsatellite loci for genetic parameters, and mtDNA (cyt b; 16S) and nuclear (RAG1; RAG2) regions for dating major lineage-splitting events within Engraulidae family. The OWA genetic divergences (0-0.4%) are compatible with intra-specific divergence, showing evidence of both ancient and contemporary admixture between the Pacific and Atlantic populations, enhanced by high asymmetrical migration from the Pacific to the Atlantic. The estimated divergence between Atlantic and Pacific anchovies (0.67 [0.53-0.80] Ma) matches a severe drop of sea temperature during the Günz glacial stage of the Pleistocene. Our results support an alternative evolutionary scenario for the OWA, suggesting a coastal migration along south Asia, Middle East and eastern Africa continental platforms, followed by the colonization of the Atlantic via the Cape of the Good Hope.

When walking becomes wandering: representing the fear of the fourth age

Dementia is linked to behavioural changes that are perceived as challenging to care practices. One such behavioural change is 'wandering', something that is often deeply feared by carers and by people with dementia themselves. Understanding how behavioural changes like wandering are experienced as problematic is critically important in current discussions about the behavioural and psychological symptoms of dementia. In this article we draw on our secondary analysis of qualitative interviews and focus groups with carers of people with dementia to critically question 'when does walking become wandering'? Drawing on theoretical perspectives from anthropology, sociology and human geography to explore experiences of carers and of people with dementia, we argue that a conceptual shift occurs in how pedestrian activity, usually represented as something purposeful, meaningful and healthy (walking) is seen as something threatening that needs managing (wandering). We demonstrate how this shift is connected to cultural assumptions about the mind-body relationship in both walking and in dementia. We further argue that the narratives of carers about wandering challenge the notion of 'aimless' walking in the fourth age. This is because, as these narratives show, there are often pronounced links to specific areas and meaningful places where people with dementia walk to.

Field Evaluations of Tracking/Locating Technologies for Prevention of Missing Incidents

BACKGROUND

Persons with dementia are at risk of a missing incident, which is defined as an instance in which a demented person's whereabouts are unknown to the caregiver and the individual is not in an expected location. Since it is critical to determine the missing person's location as quickly as possible, we evaluated whether commercially available tracking technologies can assist in a rapid recovery.

METHODS

This study examined 7 commercially available tracking devices: 3 radio frequency (RF) based and 4 global positioning system (GPS) based, employing realistic tracking scenarios. Outcome measures were time to discovery and degree of deviation from a straight intercept course.

RESULTS/CONCLUSION

Across all scenarios tested, GPS devices were found to be approximately twice as efficient as the RF devices in locating a "missing person." While the RF devices showed reasonable performance at close proximity, the GPS devices were found to be more appropriate overall for tracking/locating missing persons over unknown and larger distances.

[Nighttime restlessness in people with dementia in residential care: an explorative field study]

Nighttime restlessness in dementia is an underestimated problem. Although little is known about the prevalence and not every person with dementia struggles with it, nighttime restlessness puts a heavy burden on the persons themselves and their caregivers.This field study explores nighttime restlessness in nursing homes based on two research questions: (1) What is nighttime restlessness according to professional caregivers? and (2) How is nighttime restlessness managed?Data were collected through diaries, interviews with caregivers and one night of observation in eight nursing homes.Wandering and screaming seem to be the most prevalent nighttime agitated behaviours. Caregivers identify many possible causes, but spatial and sensory factors, such as light or noise, were rarely mentioned spontaneously. The observations highlighted that a lot of light and noise is prominent and this might be causing nighttime restlessness.Caregivers try several strategies: for example talking with the resident, put on a light and apply medication or physical restraints.The management of nighttime restlessness requires a holistic approach. Caregivers' attention for and efforts to ameliorate the spatial and sensory environment in the management of nighttime restlessness are limited.

Preliminary results of using inertial sensors to detect dementia- related wandering patterns

We present a solution for detecting dementia-related travel patterns using only inertial sensors. The results and lessons learnt from the experiments on dementia and non-dementia subjects are reported.

French Validation of the Revised Algase Wandering Scale for Long-Term Care

OBJECTIVES

The aim of this study was to create a French equivalent of the revised Algase wandering scale for long-term care (RAWS-LTC).

METHODS

The RAWS-LTC French version (F-RAWS-LTC), Mini-Mental State Examination, and Neuropsychiatric Inventory were administered to a sample of 100 institutionalized patients from 12 specialized homes.

RESULTS

The mean of the overall F-RAWS-LTC was 2.32 (standard deviation [SD]=0.74, range 1-4), and the mean of each subscale was 2.48 for persistent walking, 1.62 for eloping behavior, and 2.30 for spatial disorientation. The correlation between the overall F-RAWS-LTC and each subscale was between 0.73 (for Spatial Disorientation) and 0.87 (for Persistent Walking). The correlation between the degree of behavioral disturbances and the overall F-RAWS-LTC is 0.42, and the correlation with the cognitive impairment is 0.50. Differences between the wanderers and nonwanderers are significant for the overall F-RAWS-LTC and for all the subscales.

DISCUSSION

Data demonstrate the statistical validity of the F-RAWS-LTC.

Energy Efficient Execution of POMDP Policies

Recent advances in planning techniques for partially observable Markov decision processes (POMDPs) have focused on online search techniques and offline point-based value iteration. While these techniques allow practitioners to obtain policies for fairly large problems, they assume that a nonnegligible amount of computation can be done between each decision point. In contrast, the recent proliferation of mobile and embedded devices has lead to a surge of applications that could benefit from state-of-the-art planning techniques if they can operate under severe constraints on computational resources. To that effect, we describe two techniques to compile policies into controllers that can be executed by a mere table lookup at each decision point. The first approach compiles policies induced by a set of alpha vectors (such as those obtained by point-based techniques) into approximately equivalent controllers, while the second approach performs a simulation to compile arbitrary policies into approximately equivalent controllers. We also describe an approach to compress controllers by removing redundant and dominated nodes, often yielding smaller and yet better controllers. Further compression and higher value can sometimes be obtained by considering stochastic controllers. The compilation and compression techniques are demonstrated on benchmark problems as well as a mobile application to help persons with Alzheimer's to way-find. The battery consumption of several POMDP policies is compared against finite-state controllers learned using methods introduced in this paper. Experiments performed on the Nexus 4 phone show that finite-state controllers are the least battery consuming POMDP policies.

Development of an image processing support system based on fluorescent dye to prevent elderly people with dementia from wandering

The wandering of elderly people with dementia is a significant behavioral problem and is a heavy burden on caregivers in residential and nursing homes. Thus, warning systems have been developed to prevent elderly people with dementia from leaving the premises. Some of these systems use radio waves. However, systems based on radio waves present several practical problems. For instance, the transmitter must be carried and may become lost; in addition, the battery of the transmitter must be changed. To solve these problems, we developed a support system that prevents elderly people with dementia from wandering. The system employs image processing technology based on fluorescent dye. The composition of the support system can be described as follows: fluorescent dye is painted in a simple shape on the clothes of an elderly person. The fluorescent color becomes visible by irradiation with a long wavelength of ultraviolet light. In the present paper, the relationship between the color of the dye and the cloth was investigated. A 3D video camera was used to acquire a 3D image and detect the simple shape. As a preliminary experiment, 3 colors (red, green and blue) of fluorescent dye were applied to cloths of 9 different colors. All fluorescent colors were detected on 6 of the cloths, but red and blue dye could not be detected on the other 3 cloths. In contrast, green dye was detectable on all 9 of the cloths. Additionally, we determined whether green dye could be detected in an actual environment. A rectangular shaped patch of green fluorescent dye was painted on the shoulder area of a subject, from the scapula to the clavicle. As a result, the green dye was detected on all 9 different colored cloths.

A descriptive study of elderly patients with dementia who died wandering outdoors in Kochi Prefecture, Japan

This was a descriptive study of elderly persons with dementia who were found dead after becoming lost in the community. Nineteen forensic autopsy cases were performed at Kochi Medical School, Japan. The mean age of the patients (9 males and 10 females) was 82.1 ± 6.6 years. Causes of death were drowning (n = 8), trauma (n = 5), hypothermia (n = 2), and debilitation possibly due to fatigue (n = 1) or were unknown (n = 3). Thirteen (68%) individuals had been reported missing, most at least 6 hours after they had left. They moved on foot (n = 14), by car (n = 3), or by bicycle (n = 2). Distances from residences to spots of death ranged from 20 to 5800 m for 11 patients on foot. In 8 cases, it was less than 500 m. The study has potential implications for enabling their early discovery and protection.

Development of a Daily Life Support System for Elderly Persons with Dementia in the Care Facility

Taking care for dementia persons with BPSD is burdening on caregivers. To reduce caregivers' burdens and improve dementia persons' quality of life, monitoring and communication intervention system has been proposed. A part of the system, wandering and falling down detection system has been developed. It is designed based on the requirement of the caregivers working in the care facility. Functional test was carried out and had positive impressions from the caregivers.

A comprehensive profile of the sociodemographic, psychosocial and health characteristics of Ontario home care clients with dementia

INTRODUCTION

This study provides a comprehensive summary of the sociodemographic, psychosocial and health characteristics of a large population-based cohort of Ontario home care clients (aged 50 years and over) with dementia and examines the variation in these characteristics in those with co-existing neurological conditions.

METHODS

Clients were assessed with the Resident Assessment Instrument-Home Care (RAI-HC) between January 2003 and December 2010. Descriptive analyses examined the distribution of these characteristics among clients with dementia relative to several comparison groups, as well as clients with other recorded neurological conditions.

RESULTS

Approximately 22% of clients (n=104 802) had a diagnosis of dementia (average age 83 years, 64% female) and about one in four within this group had a co-existing neurological condition (most commonly stroke or Parkinson disease). About 43% of those with dementia did not live with their primary caregiver. Relative to several comparison groups, clients with dementia showed considerably higher levels of cognitive and functional impairment, aggression, anxiety, wandering, hallucinations/delusions, caregiver distress and a greater risk for institutionalization. Conversely, they showed a lower prevalence of several chronic conditions and lower levels of recent health service use. Depressive symptoms were relatively common in the dementia and other neurological groups.

CONCLUSION

Clients with co-existing neurological conditions exhibited unique clinical profiles illustrating the need for tailored and flexible home care services and enhanced caregiver assistance programs.

[How to avoid and how to react to the wandering behavior of a patient]

The consequences of the wandering off a patient can be serious, even irreversible, for the integrity of the person as well as that of third parties. Hence the importance of preventing these situations for which, when they occur, responsibilities are sought.

Safe home program: a suite of technologies to support extended home care of persons with dementia

OBJECTIVE

To report the implementation/adoption of the Safe Home Program to support caregivers of persons with dementia in (1) ongoing surveillance, (2) provision of care, (3) prevention of injuries, and (4) improving home safety.

METHODS

For this demonstration project 4 assessment questionnaires (Safety Assessment Scale, Vigilance Scale, Peace of Mind Scale, and Sleep Disorders Inventory) were administered to each dyad to understand their technological needs. After identification and installation of appropriate technologies and education of the caregiver, a final visit (at 3 months) determined whether technologies were useful and being used.

RESULTS

The majority of caregivers utilized technologies for ongoing surveillance; other technologies included an identification program and medication organizer.

CONCLUSION

Technologies focused on ongoing surveillance for persons with dementia at the home are needed. These technologies could be quickly adopted by caregivers to ameliorate some of the stress and burden associated with providing care for persons with dementia.

Programs to locate missing and critically wandering elders: a critical review and a call for multiphasic evaluation

As America ages, greater numbers of older adults will be living with Alzheimer's disease or a related dementia, leading to increased incidence of wandering. Currently there are several initiatives to assist older adults who go missing. We describe and critically examine three prominent and widespread programs: Safe Return, Project Lifesaver, and Silver Alert. Despite their emergence, there has been little research on their effectiveness. More fundamentally, the nature and scope of the missing elder problem is understudied. We call for further research into this issue, as well as assessments of how well such programs balance individual liberties with safety concerns.

A physical security evaluation tool for elopement prevention in a behavioural/mental health setting

The design of an elopement evaluation tool which enabled a physical security review of 53 Behavioural/Mental Health (BMH) units located in three stand-alone BMH facilities and within 14 acute care hospitals in the Alberta Health Services (AHS), the largest healthcare organization in Canada, is described in this article. The tool, according to the author, was successfully used to assess units for risk of elopement and deliver recommendations to address identified risks and deficiencies. It can be used, he says, across a broad spectrum of care environments, and be adapted by users to meet their specific needs.

A mobile-health application to detect wandering patterns of elderly people in home environment

Wandering is a common and risky behavior in people with dementia (PWD). In this paper, we present a mobile healthcare application to detect wandering patterns in indoor settings. The application harnesses consumer electronics devices including WiFi access points and mobile phones and has been tested successfully in a home environment. Experimental results show that the mobile-health application is able to detect wandering patterns including lapping, pacing and random in real-time. Once wandering is detected, an alert message is sent using SMS (Short Message Service) to attending caregivers or physicians for further examination and timely interventions.

Nonpharmacologic management of behavioral symptoms in dementia

Behavioral symptoms such as repetitive speech, wandering, and sleep disturbances are a core clinical feature of Alzheimer disease and related dementias. If untreated, these behaviors can accelerate disease progression, worsen functional decline and quality of life, cause significant caregiver distress, and result in earlier nursing home placement. Systematic screening for behavioral symptoms in dementia is an important prevention strategy that facilitates early treatment of behavioral symptoms by identifying underlying causes and tailoring a treatment plan. First-line nonpharmacologic treatments are recommended because available pharmacologic treatments are only modestly effective, have notable risks, and do not effectively treat some of the behaviors that family members and caregivers find most distressing. Examples of nonpharmacologic treatments include provision of caregiver education and support, training in problem solving, and targeted therapy directed at the underlying causes for specific behaviors (eg, implementing nighttime routines to address sleep disturbances). Based on an actual case, we characterize common behavioral symptoms and describe a strategy for selecting evidence-based nonpharmacologic dementia treatments. Nonpharmacologic management of behavioral symptoms in dementia can significantly improve quality of life and patient-caregiver satisfaction.

[Difference in sundowning of wandering behavior in patients with Alzheimer disease and frontotemporal dementia]

OBJECTIVES

To delineate the difference in sundowning of wandering behavior between patient with Alzheimer Disease (AD) and frontotemporal dementia (FTD).

METHODS

The study was conducted in a dementia care unit at A hospital in Osaka, Japan from September 2008 to September 2009. Twenty-four-hour movements of 27 ambulatory inpatients with AD and 7 with FTD were coded consecutively by the IC tag monitoring system.

RESULTS

Repeated measures ANOVA after the adjustment of Huynh-Feldt Epsilon (H-F) showed no significant difference in 24 h standardized activity level between two groups (F = 3.74, P = 0.06), and there was no interaction between diagnosis and time (F = 1.42, P > 0.05). The standardized activity levels gradually increased from late afternoon to evening and then reached the highest point at 18:00 in AD group and 19:00 in FTD group. Test of within-subjects contrasts for order 17 was significant (F = 5.24, P < 0.05) and for order 9 was a tendency of significant (F = 4.26; P = 0.05) between two groups. AD group was significant greater active at 5:00, 6:00 and 7:00 (0.75 ± 0.08 vs 0.35 ± 0.16, F = 4.91; 1.13 ± 0.13 vs 0.49 ± 0.26, F = 5.06; 1.24 ± 0.15 vs 0.56 ± 0.28, F = 4.47 respectively, P < 0.05), and less active at 16:00 (1.65 ± 0.11 vs 2.22 ± 0.22, P < 0.05) comparing to FTD group by Bonferroni's multiple comparison test. Meanwhile, the time of peak value of hourly distance moved per day (PV-time) was delayed in FTD group comparing to AD by circular χ² test (14:12 ± 5:12 vs 15:47 ± 4:19, χ² = 87.31, P < 0.01).

CONCLUSIONS

The study suggests great possibility of sundowning of wandering behavior in both two subtypes with different temporal pattern of wandering behavior. Comparing to FTD patients, AD patients showed an advanced PV-time and prolonged active phase.

Hospital security and patient elopement: protecting patients and your healthcare facility

Regulatory and financial consequences of adverse events associated with patient elopements are bringing new challenges to healthcare security to develop policies and procedures to prevent and respond to such incidents. This article provides an overview of the problem of elopement in healthcare and what it means to the security function; gives a working knowledge of healthcare related standards and guidelines aimed at reducing patient elopement; and reviews the elements of an elopement prevention and response plan for your organization.

An approach to geotracking patients with Alzheimer's disease

Recently, numerous systems for geo-tracking Alzheimer's patients with dementia have been developed and reported to be functional for the purposes of security and data collection. However, studies stated possible loss of freedom and autonomy for patients, along with violations of their privacy, which may lead to loss of prestige/dignity. In this study, a geotracking system that aims to balance patients' security and their need for privacy and autonomy is proposed. The system introduces a personalized, four-level temporal geofence based tracking, warning and notification protocol that incorporates a safety check mechanism operating over Global System for Mobile Communications network.

[Alzheimer's disease and geolocation: initial results of the Estima study]

Geolocation devices for patients suffering from Alzheimer's disease constitute an improvement in their care. However, this system arouses debate. The Estima study offers a series of results and recommendations concerning the use of these devices. It consists of three complementary sections: a sociological study, an observational retrospective study and an ethical analysis.

The informal caregivers' perception of wandering

Although the term wandering is routinely used by clinicians, researchers, and informal caregivers (ICs), the meaning of this term varies depending on the source of the definition and the context in which it is used. The purpose of this study was to examine the terms ICs used to describe different scenarios that have been identified in literature as "wandering," determine their perception of risk, and compare their definitions of wandering with the perspectives of researchers. Structured interviews were conducted with 128 ICs of older adults with dementia. Informal Caregivers rarely used the term wandering to label different scenarios that had been previously identified in the literature as wandering. Responses to a survey of 17 wandering experts did not reflect agreement on a definition for wandering. These findings suggest that a broad set of terms should be used to describe this potentially dangerous behavior when health care providers communicate with ICs.

Families' and professional caregivers' views of using advanced technology to track people with dementia

in this study we examined the ethical aspects of the use of the Global Positioning Systems (GPS) to track people with dementia. The findings are based on qualitative data gathered from focus groups of family and professional caregivers. The most important theme was the need to balance patients' need for safety with the need to preserve their autonomy and privacy. The main potential benefit of the use of GPS was related to the peace of mind of the caregivers themselves. The findings also suggest that caregivers' views change according to the locus of responsibility of the caregivers for the safety of people with dementia. The caregivers give preference to patients' safety more than autonomy when they are responsible for the patients. When the patients are under the responsibility of other caregivers, they give preference to patients' autonomy more than their safety. Overall, the variety and the depth of the views of different stakeholders toward the use of electronic tracking for people with dementia presented in this article provide a meaningful contribution to the ethical debate on this topic.

Pacing and lapping movements among institutionalized patients with dementia

Wandering is a complex behavior, and defining wandering has been challenging. The current study used the integrated circuit (IC) tag monitoring system to describe the distance moved per day and the spatial movements of patients with dementia. The study was conducted in a 60-bed semiacute dementia care unit in a general hospital in Japan over a 3-month period in 2006. The distance moved per day, the numbers of pacing and lapping movements, and the proportions of the distance moved that was paced or lapped were tabulated in 23 patients diagnosed with dementia. The distance moved per day and the numbers of pacing and lapping movements varied greatly within and among study participants. The median distance moved per day was inversely correlated with participants' age and Mini-Mental State Examination (MMSE) scores (adjusted r(2) = .34, P = .01). Consecutive lapping and pacing movements were rare patients with in Alzheimer's disease (AD), while 2 patients with frontotemporal dementia paced or lapped repeatedly.

Dementia-friendly architecture: environments that facilitate wayfinding in nursing homes

Spatial disorientation is a prime reason for institutionalization. The autonomy of the residents and their quality of life, however, is strongly linked with their ability to reach certain places within their nursing home. The physical environment has a great potential for supporting a resident's wayfinding abilities. For this study, data were collected from 30 German nursing homes. Skilled nurses rated the resident's ability to perform 5 wayfinding tasks. The architectural characteristics of the homes were analyzed and their impact on the resulting scores was tested for statistical significance using the Mann-Whitney U test (P < .05). Results confirm that people with advancing dementia are increasingly dependent on a compensating environment. The significant factors include a small number of residents per living area, the straight layout of the circulation system without any changes in direction, and the provision of only 1 living/dining room. These and additional results were transformed into architectural guidelines.

Treatment of elopement in individuals with developmental disabilities: a systematic review

We reviewed studies involving the treatment of elopement in individuals with developmental disabilities. Systematic searches of three electronic databases, journals, and reference lists identified 10 studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participants, (b) procedures used to assess elopement, (c) intervention procedures, (d) results of the intervention, and (e) certainty of evidence. Across the 10 studies, intervention was provided to a total of 53 participants aged 3-47 years. Assessment procedures included anecdotal staff reports, participant interviews, direct observation, and modified analog functional analysis. Intervention approaches included differential reinforcement, extinction, functional communication training, response blocking, non-contingent reinforcement, shaping, and scheduled exercise. Positive outcomes were reported in 80% of the reviewed studies. The evidence base suggests that function-based assessment (e.g. functional analysis procedures) and function-based treatments (e.g. functional communication training) may be most effective in the treatment of elopement in this population. Directions for future research are offered.

A framework for managing wandering and preventing elopement

PURPOSE OF THE STUDY

A framework aids choice of interventions to manage wandering and prevent elopement in consideration of associated risks and mobility needs of wanderers.

DESIGN AND METHODS

A literature review, together with research results, published wandering tools, clinical reports, author clinical experience, and consensus-based judgments was used to build a decision-making framework.

RESULTS

Referencing a published definition of wandering and originating a clinical description of problematic wandering, authors introduce a framework comprising (1) wandering and related behaviors; (2) goals of wandering-specific care, (3) interpersonally, technologically, and policy-mediated wandering interventions, and (4) estimates of relative frequencies of wandering behaviors, magnitudes of elopement risk, and restrictiveness of strategies.

IMPLICATIONS

Safeguarding wanderers from elopement risk is rendered person-centered and humane when goals of care guide intervention choice. Despite limitations, a reasoned, systematized approach to wandering management provides a basis for tailoring a specialized program of care. The need for framework refinement and related research is emphasized.

Improving caregivers' well-being by using technology to manage nighttime activity in persons with dementia

This article reports the qualitative arm of a mixed-methods study designed to test an in-home nighttime monitoring system (NMS) that tracks the nighttime activity of persons with dementia. Fourteen caregiver interviews were analyzed using grounded theory/full conceptual description methods to determine the issues associated with providing care at night and to explore the benefits of using the NMS. Caregivers not using the NMS experienced sleep disruption, overwhelming worry, and loss of personal space, leading to decreased energy and changes in mood. When the NMS was used, caregivers reported improved "peace of mind." The fear and uncertainty associated with worry was alleviated by reliable alerts regarding the whereabouts of the person with dementia. Some caregivers were able to better balance needs for personal space with needs to remain in contact with the person with dementia. Generally, caregivers reported improved quality of sleep, although some caregivers reported more awakenings due to the system alerts.
