The informal caregivers' perception of wandering

Influence of perspectives on user adoption of wander-management strategies

Sixty-percent of Canadians with dementia will wander and become lost. Strategies, such as wall murals that camouflage doors, and locator devices, offer proactive options for keeping persons with dementia who wander safer. Information that describes available strategies to mitigate this issue is diverse and inconsistent, creating challenges for caregivers and persons living with dementia when choosing helpful strategies. This project aimed to describe the spectrum of risks and risk mitigation strategies associated with dementia-related wandering. Thirty-eight phone interviews from across Canada were conducted with stakeholders including persons with dementia, paid and family caregivers, health professionals, law enforcement, and Alzheimer societies. Interviewees were asked about strategies that they have used to manage dementia-related wandering, and how their perceptions of risk, culture, stigma and geographical location may influence strategy adoption. Overall, a wide range of high- and low-tech solutions were used or suggested by participants, and factors such as risk, culture, geography and stigma were considered essential elements to successful adoption of these strategies. Results from this study highlight the need for unique combinations of strategies based on the type of stakeholder and influencing factors involved.

Risk assessment of wandering behavior in mild dementia

OBJECTIVE

This prospective longitudinal study aims to determine the risk factors of wandering-related adverse consequences in community-dwelling persons with mild dementia. These adverse consequences include negative outcomes of wandering (falls, fractures, and injuries) and eloping behavior.

METHODS

We recruited 143 dyads of persons with mild dementia and their caregivers from a veteran's hospital and memory clinic in Florida. Wandering-related adverse consequences were measured using the Revised Algase Wandering Scale - Community Version. Variables such as personality (Big Five Inventory), behavioral response to stress, gait, and balance (Tinetti Gait and Balance), wayfinding ability (Wayfinding Effectiveness Scale), and neurocognitive abilities (attention, cognition, memory, language/verbal skills, and executive functioning) were also measured. Bivariate and logistic regression analyses were performed to assess the predictors of these wandering-related adverse consequences.

RESULTS

A total of 49% of the study participants had falls, fractures, and injuries due to wandering behavior, and 43.7% demonstrated eloping behaviors. Persistent walking (OR = 2.6) and poor gait (OR = 0.9) were significant predictors of negative outcomes of wandering, while persistent walking (OR = 13.2) and passivity (OR = 2.55) predicted eloping behavior. However, there were no correlations between wandering-related adverse consequences and participants' characteristics (age, gender, race, ethnicity, and education), health status (Charlson comorbidity index), or neurocognitive abilities.

CONCLUSION

Our results highlight the importance of identifying at-risk individuals so that effective interventions can be developed to reduce or prevent the adverse consequences of wandering.

The Concept of Missing Incidents in Persons with Dementia

Behavioral symptoms of dementia often present the greatest challenge for informal caregivers. One behavior, that is a constant concern for caregivers, is the person with dementia leaving a designated area such that their whereabouts become unknown to the caregiver or a missing incident. Based on an extensive literature review and published findings of their own research, members of the International Consortium on Wandering and Missing Incidents constructed a preliminary missing incidents model. Examining the evidence base, specific factors within each category of the model were further described, reviewed and modified until consensus was reached regarding the final model. The model begins to explain in particular the variety of antecedents that are related to missing incidents. The model presented in this paper is designed to be heuristic and may be used to stimulate discussion and the development of effective preventative and response strategies for missing incidents among persons with dementia.
