Risk assessment of wandering behavior in mild dementia

Pan-Canadian estimates of the prevalence and risks associated with critical wandering among home care clients

INTRODUCTION

We used clinical assessment records to provide pan-Canadian estimates of the prevalence and risks associated with recent (within the last 3 days) critical wandering among home care clients, with and without dementia.

METHODS

The data source is interRAI Home Care (interRAI HC) assessments. The population was all long-stay home care clients assessed between 2004 and 2021 in seven Canadian provinces and territories (N = 1,598,191). We tested associations between wandering and cognition and dementia diagnoses using chi-square tests and logistic regression.

RESULTS

Approximately 84% of the sample was over the age of 65. The overall rate of recent wandering was 3.0%. Dementia diagnosis was strongly associated with two to four times higher rates in the prevalence of recent critical wandering.

DISCUSSION

InterRAI HC offers insights into the wandering risk of home care clients. This information should be used to manage risks in the community and could be shared with first responders.

HIGHLIGHTS

In all the study regions combined, the rate of recent wandering is 3.0%. Dementia was associated with 18 times greater prevalence of recent critical wandering. Home care clients at risk of wandering have complex clinical profiles that pose important risks for their health and well-being. Collaboration and information sharing between search and rescue and health professions is essential for managing risks related to critical wandering.

Non-pharmacological management of wandering in persons with dementia: an integrative review

BACKGROUND

Wandering behaviour affects a significant portion of dementia patients, ranging from 15% to 80%, presenting a serious safety concern and adding to caregivers' burden. Recent studies emphasise the effectiveness of non-pharmacological interventions over pharmacological ones due to their minimal side effects. Consequently, in current literature there has been a surge of interest in exploring non-pharmacological methods for managing wandering.

PURPOSE

This integrative literature review aims to deepen comprehension of wandering behaviour, presents recent studies on non-pharmacological approaches, and inspires further research in this field.

METHODS

Electronic data collection spanned from 2019 to 2024, sourcing 20 relevant articles from PubMed and Scopus databases using search terms such as 'dementia', 'Alzheimer's disease', 'wandering', and 'management'. A thematic analysis methodology was employed to identify non-pharmacological treatment themes for managing wandering. This approach involves scrutinising and synthesising themes within the dataset. Qualitative data analysis focused on significant phrases and keywords, grouping them to derive relevant themes.

RESULTS

Recent literature extensively explores non-pharmacological methods for managing wandering. These include understanding behaviours, identifying and targeting high-risk groups, facilitating safe wandering, addressing environmental factors, promoting exercise and activity, and offering caregiver support.

CONCLUSIONS

This study significantly advances understanding of wandering behaviour and highlights recent research on non-pharmacological interventions. The findings suggest the potential for providing safe and effective treatment to wandering dementia patients, thereby alleviating stress for both patients and caregivers.

Risk assessment for people living with dementia: a systematic review

OBJECTIVE

This systematic review identified key components of risk assessment for people with dementia, examined attitudes toward risk identification and risk assessment, and appraised existing risk assessment tools.

METHODS

Systematic searches of five databases on two platforms (EBSCO, OVID) and gray literature databases (Open Grey, Base) were conducted. Studies were screened for inclusion based on predetermined eligibility criteria and quality assessed using the Mixed Methods Appraisal Tool. Findings were tabulated and synthesized using thematic synthesis.

RESULTS

Our review found people with dementia, their family carers, and healthcare professionals differed in how risk is conceptualized, with views being shaped by media perceptions, personal experiences, socio-cultural influences, dementia knowledge, and dementia severity. We found that mobilization (causing falls inside and getting lost outside) is the most frequently identified risk factor. Our findings show people with dementia are generally risk-tolerant, while healthcare professionals may adopt risk-averse approaches because of organizational requirements. We found factors that disrupt daily routines, living and caring arrangements, medication management, and unclear care pathways contribute toward adverse risk events. We discovered that most studies about risk and risk assessment scales did not consider insight of the person with dementia into risks although this is important for the impact of a risk. No risk instrument identified had sufficient evidence that it was useful.

CONCLUSION

Accurate risk assessment and effective communication strategies that include the perspectives of people with dementia are needed to enable risk-tolerant practice. No risk instrument to date was shown to be widely acceptable and useful in practice.

Risk Factors Associated with Missing Incidents among Persons Living with Dementia: A Scoping Review

Worldwide, over 55-million people have dementia, and the number will triple by 2050. Persons living with dementia are exposed to risks secondary to cognitive challenges including getting lost. The adverse outcomes of going missing include injuries, death, and premature institutionalization. In this scoping review, we investigate risk factors associated with going missing among persons living with dementia. We searched and screened studies from four electronic databases (Medline, CINAHL, Embase, and Scopus), and extracted relevant data. We identified 3,376 articles, of which 73 met the inclusion criteria. Most studies used quantitative research methods. We identified 27 variables grouped into three risk factor domains: (a) demographics and personal characteristics, (b) health conditions and symptoms, and (c) environmental and contextual antecedents. Identification of risk factors associated with getting lost helps to anticipate missing incidents. Risk factors can be paired with proactive strategies to prevent incidents and inform policies to create safer communities.

An Integrative Review of the Feasibility and Effects of the Use of Location-Tracking Devices by Persons Living With Cognitive Impairment

OBJECTIVES

This study aimed to examine the effects of location-tracking devices on persons living with cognitive impairment, investigate facilitators of and barriers to using the devices, and provide future directions for the use of the devices.

METHODS

An integrative review was conducted using 5 databases: PubMed, Embase, Web of Science, CINAHL, and Scopus. From the 1429 initially identified studies, 10 were included in the review.

RESULTS

Location-tracking devices benefited persons living with cognitive impairment and their informal caregivers. The devices brought more independence to persons living with cognitive impairment, allowing them to go outside and feel safer there. Furthermore, the devices reduced the caregivers' worries about their loved ones being lost.

CONCLUSIONS

Location-tracking devices have the potential to increase independence in persons living with cognitive impairment and to decrease psychological stress in informal caregivers. In the future, ways to minimize the barriers to using location-tracking devices need to be determined.

Exploring a Novel Tool to Measure Wandering Behavior in the Early Childhood Classroom

Wandering, or random movement, affects cognitive and social skills. However, we lack methods to objectively measure wandering behavior. The purpose of this pilot study was to explore the use of the Ubisense real-time location system (RTLS) in an early childhood setting to explore wandering in typically developing (TD) children (n = 2) and children with or at risk for developmental disabilities (WA-DD; n = 3). We used the Ubisense RTLS, a tool for capturing locations of individuals in indoor environments, and Fractal Dimension (FD) to measure the degree of wandering or the straightness of a path. Results of this descriptive, observational study indicated the Ubisense RTLS collected 46,229 1-s location estimates across the five children, and TD children had lower FD (M = 1.36) than children WA-DD (M = 1.42). Children WA-DD have more nonlinear paths than TD children. Implications for measuring wandering are discussed.

Approach to Management of Wandering in Dementia: Ethical and Legal Issue

Wandering behavior is one of the most important and challenging management aspects in persons with dementia. Wandering behavior in people with dementia (PwD) is associated with an increased risk of falls, injuries, and fractures, as well as going missing or being lost from a facility. This causes increased distress in caregivers at home and in healthcare facilities. The approach to the comprehensive evaluation of the risk assessment, prevention, and treatment needs more strengthening and effective measures as the prevalence of wandering remains high in the community. Both the caregiver and clinicians need a clear understanding and responsibility of ethical and legal issues while managing and restraining the PwD. Ethical and legal issues especially in the light of the new Indian Mental Healthcare Act of 2017, related to confinement by family members in their homes by family caregivers, seclusion, physical or chemical restraints, other pharmacological and behavioral treatment, highlighting their effectiveness as well as adverse consequences are discussed. This article attempts to address an approach in managing wandering behavior in PwD in light of MHCA, 2017.

Detection of Wandering Behaviors Using a Body-Worn Inertial Sensor in Patients With Cognitive Impairment: A Feasibility Study

Patients with Alzheimer's disease (AD) and AD related dementias (ADRD) often experience spatial disorientation that can lead to wandering behavior, characterized by aimless or purposeless movement. Wandering behavior has been associated with falls, caregiver burden, and nursing home placement. Despite the substantial clinical consequences of wandering, there is currently no standardized approach to objectively quantify wandering behavior. In this pilot feasibility study, we used a lightweight inertial sensor to examine mobility characteristics of a small group of 12 older adults with ADRD and mild cognitive impairment in their homes. Specifically, we evaluated their compliance with wearing a sensor for a minimum of 4 days. We also examined the ability of the sensor to measure turning frequency and direction changes, given that frequent turns and direction changes during walking have been observed in patients who wander. We found that all patients were able to wear the sensor yielding quantitative turn data including number of turns over time, mean turn duration, mean peak turn speed, and mean turn angle. We found that wanderers make more frequent, quicker turns compared to non-wanderers, which is consistent with pacing or lapping behavior. This study provides preliminary evidence that continuous monitoring in patients with dementia is feasible using a wearable sensor. More studies are needed to explore if objective measures of turning behaviors collected using inertial sensors can be used to identify wandering behavior.

Evaluation of antecedent behaviors of dementia-related wandering in community and facility settings

Aim: To understand antecedent behaviors to critical wandering among persons living with dementia in or outside of a facility. Materials & methods: Caregivers were asked to write down the type and number of antecedent behaviors they observed in persons with dementia that were about to critically wander for 2-4 weeks. Observations were made through a developed questionnaire. Results: Six antecedent behaviors were observed: stating intent to leave, door lingering/tampering, preparing to go outside, packing up belongings, calling to be picked up and draw to outside stimuli. Conclusion: Information from this study can be used in the education of wander-management strategy adoption among caregivers of persons with dementia at risk of getting lost.

Neuropsychiatric Symptoms as Predictors of Falls in Long-Term Care Residents With Cognitive Impairment

OBJECTIVES

Falls and neuropsychiatric symptoms (NPS) are common among long-term care residents with cognitive impairment. Despite the high prevalence of falls and NPS, little is known about their association. The aim of our study was to explore how NPS, particularly the severity of NPS and specific NPS subgroups, are associated with falls and how psychotropics modify this association.

DESIGN

Longitudinal cohort study.

SETTING AND PARTICIPANTS

In total, 532 long-term care residents aged 65 years or older in Helsinki, Finland.

METHODS

NPS were measured with Neuropsychiatric Inventory (NPI) at baseline. Participants were grouped into 3 groups: no significant NPS (NPI points 0‒3), low NPS burden (NPI 4‒12), and high NPS burden (NPI >12). The number of falls, injuries, fractures, and hospitalizations were collected from medical records over 12 months following baseline assessment.

RESULTS

Altogether, 606 falls occurred during the follow-up year. The falls led to 121 injuries, 42 hospitalizations, and 20 fractures. Falls and injuries increased significantly with NPS burden (P < .001): 330 falls in the high NPS group (n = 184), 188 falls in the low NPS group (n = 181), and 88 falls in the no significant NPS group (n = 167). The risk of falling showed a curvilinear association with NPI total score. Of NPS subgroups, psychosis and hyperactivity were associated with a higher incidence rate ratio of falls, whereas apathy had a protective association even after adjustment for age, sex, and mobility. Affective symptoms were not associated with falls. Psychotropics did not modify the association between NPS burden and falls.

CONCLUSIONS AND IMPLICATIONS

The results of this study show that NPS, especially NPS severity, may predict falls and fall-related negative consequences. Severity of NPS should be taken into account when assessing fall risk in long-term care residents with cognitive impairment.

Gender differences in presentation and management of behavioral and psychological symptoms associated with dementia among nursing home residents with moderate to severe dementia

Lack of identification and management of behavioral and psychological symptoms of dementia (BPSD) can negatively impact female residents. The purpose of this secondary data analysis was to explore gender differences in presentation and management of BPSD and quality of interactions between residents and staff. A total of 553 residents from 55 nursing homes were included. Males exhibited more apathy and sexually inappropriate behavior and females exhibited more anxiety and sadness. Anxiety and sexually inappropriate behavior were more likely to be addressed in care plans for males than females. There was no difference in how staff interacted with males or females.

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.].

Differences Between Moderate to Severely Cognitively Impaired Fallers Versus Nonfallers in Nursing Homes

INTRODUCTION

The purpose of this study was to test differences in psychotropic medication, function, physical activity, agitation, resistiveness to care, comorbidities, and depression among moderate to severely cognitively impaired nursing home residents who were fallers versus nonfallers.

METHODS

This was a secondary data analysis using baseline data from a randomized controlled trial testing the Function and Behavior Focused Care intervention across 12 nursing homes. The sample included 336 older adults, the majority of whom were female and white.

RESULTS

There was a significant difference in the total number of comorbidities, agitation, the total number of psychotropic medications, depressive symptoms, and physical activity between those who fell and those who did not fall (Pillai-Bartlett trace = 4.91; P < .001).

DISCUSSION

Findings support prior work except with regard to medication use, cognition, and function. Due to inconsistent findings, additional research is recommended particularly with regard to the use of specific drug groups and medications.

Wandering Behaviors and Activities of Daily Living Among Older Adults With Cognitive Impairment

PURPOSE

The aim of the study was to examine the characteristics of wandering associated with preserved versus worsened activities of daily living (ADL) function.

DESIGN

Longitudinal prospective design. Twenty-two cognitively impaired residents of an assisted living facility with over 450 observations were followed up to 8 months.

METHODS

Hierarchical linear modeling techniques examine how wandering activity (episodes, distance traveled, gait speed), measured by a real-time locating system, may affect ADL (the Barthel index, the Functional Independence Measure [FIM]).

FINDINGS

Wandering episodes were associated with increased ADL (B = 0.11, p ≤ .05, FIM); wandering distance (B = -4.52, p ≤ .05, the Barthel index; B = -2.14, p ≤ .05, FIM) was associated with decreased ADL.

CONCLUSION

Walking an average of 0.81 miles per week with 18 or fewer wandering episodes is associated with decreased ability to perform ADL.

CLINICAL RELEVANCE

Tailored protocols that allow productive wandering with ongoing assessment for fatigue/other physiological needs to appropriately limit distance walked within wandering episodes are needed for this population.

Factors Associated With Wandering Behaviors in Veterans With Mild Dementia: A Prospective Longitudinal Community-Based Study

OBJECTIVE

To investigate baseline factors associated with caregiver-reported wandering among community-dwelling veterans with mild dementia.

METHODS

Veterans with mild dementia (N = 143) and their caregivers participated in a 2-year prospective longitudinal study. Measures assessed wandering, daily function, behavior, cognition, and personality features. Wandering was dichotomized as present or absent across study periods, and associations with baseline characteristics were examined.

RESULTS

One-quarter of participants demonstrated caregiver-reported wandering at 1 or more study visits, with 14% to 15% wandering at any 1 visit. Wandering was associated with significantly lower baseline scores in performance of daily function, behavioral response to stress, gait, and balance, and conscientiousness.

CONCLUSIONS

This novel study evaluated wandering in a community-dwelling sample of veterans with mild dementia. Wandering was associated with a specific personality trait, poorer behavioral response to stress as well as greater functional and gait/balance impairment. These findings may assist in developing community-based interventions for caregivers.

Systematic review of evidence underpinning non-pharmacological therapies in dementia

Objective Dementia is one of the most common illnesses worldwide, and is one of the most important causes of disability in older people. Currently, dementia affects over 35 million people around the globe. It is expected that this number will increase to 65.7 million by 2030. Early detection, diagnosis and treatment to control the principal behaviour symptoms may help reduce these numbers and delay the progression to more advanced and dangerous stages of this disorder with resultant increase quality of life for those affected. The main goal of the present systematic literature review was to examine contemporary evidence relating to non-pharmacological therapy in the treatment of dementia. Methods To achieve the study goal, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used. Results This study identified the five most common behaviours in patients with dementia as aggression, wandering, agitation, apathy and sleep disturbances. Two non-pharmacological therapies were the most studied treatment: music therapy and aromatherapy. Ten other non-pharmacological therapies were also identified, but these lack a sufficient evidence-base. Conclusion Although all the therapies identified could be used as part of the treatment of behavioural symptoms, there is insufficient evidence relating to the indications, appropriate use and effectiveness of these therapies to apply in each behavioural treatment. Thus, the present study has demonstrated a significant research gap. What is known about the topic? Despite the widespread use of many different types of therapies, there is limited evidence regarding the efficacy of non-pharmaceutical therapies deployed in the management of behaviours of concern manifested by some people who suffer with dementia in all its forms. What does this paper add? This systematic review examines contemporary evidence from the literature to determine whether there is an evidence base available that would underpin the use of these therapies. This report on a PRISMA systematic review of the available literature demonstrates that only two therapies have some evidence to underpin the use of these non-pharmaceutical therapies and that a significant research gap is exists. What are the implications for practitioners? The implications for practitioners is that significant research effort is required to determine the efficacy of many of the therapies that are currently deployed, and thus many of the therapies used lack an evidence base at this time.

Development and validation of the Korea Dementia Comorbidity Index (KDCI): A nationwide population-based cohort study from 2002 to 2013

This study develop and validate a simple and accessible measure of comorbidity, named the Korean Dementia Comorbidity index (KDCI), to assist in predicting the onset of dementia. This study used the National Health Insurance Service-Cohort Sample Database from 2002 to 2013 (n=23,856). Cox proportional hazard model was used to estimate incident dementia (International Classification of Disease, 10th edition (ICD-10) codes: F00-F03, G30, G311), with a hazard ratio higher than 1.05 for each comorbid condition being assigned a score. Scores ranging from 1 to 4 were assigned based on the magnitude of the hazard ratio (HR): 1 (1.050≤HR≤1.099), 2 (1.100≤HR≤1.149), 3 (1.150≤HR≤1.199), and 4 (HR≥1.200) Summated scores of comorbidities for each individual constituted the Korean Dementia Comorbidity Index (KDCI). Five patterns were extracted: (1) disease of the eye and adnexa; (2) endocrine and metabolic disease, and disease of circulatory system; (3) disease of the musculoskeletal system and connective tissue; (4) disease of the respiratory system; and (5) disease of the nervous system, and mental and behavioral disorders through factor analysis. Fitting performance by Akaike information criterion (AIC) of CCI by Charlson, CCI by Quan and KDCI adjusting for age and sex was 29,486, 29,488 and 29,444, respectively. Our analysis results on discriminatory abilities provided evidence that KDCI is superior to other comorbidity indices on incident dementia in terms of comorbidity adjustment. Therefore, KDCI can be a useful tool to identify incident dementia. This has implications for clinical management of patients with multimorbidity as well as risk adjustment for database studies.
