Strategies to support safe wandering in care homes for older adults – what works, for whom, and in which circumstances?: A realist synthesis

Objectives

Wandering is a common behaviour among people with dementia living in care homes, driven by various factors such as enjoyment, a sense of purpose, lifelong habits, and social interaction. These elements can bring both physical and mental benefits, highlighting the need for strategies that enable safe wandering while respecting individual autonomy. This realist synthesis aimed to explore these strategies and the conditions under which they lead to successful outcomes.

Methods

This realist synthesis involved scoping the literature to develop initial theoretical explanations for how different strategies could support safe wandering. From this literature, we developed context-mechanism-outcome configurations, which we combined into initial programme theories. Systematic searches were then used to test and refine these programme theories. Studies were prioritised for inclusion based on criteria of relevance and richness. We extracted data pertinent to the initial programme theories and documented relevance, richness, and rigour. We synthesised data into five refined programme theories. At each stage of the process, we collaborated with stakeholders to develop and validate the strategies.

Results

The review included 79 evidence sources, leading to five refined programme theories. 1) Personalised Care: Emphasising the importance of staff practicing person-centred care by understanding residents, their reasons for wandering, and their life histories. 2) Monitoring: Effective monitoring requires good visual access or technological solutions that enable staff to observe residents, and detect when residents need support to walk while also enabling resident freedom and independence. 3) Navigation: Navigation is facilitated by dementia-friendly design features and environmental cues, which help minimise the challenges residents face due to diminished orientation and wayfinding abilities. 4) Managing access: Involving balancing residents' safety and autonomy. Strategies may include restricting access to unsafe areas by locking doors or using technology and camouflage, while ensuring access to safe spaces. 5) Hydration and nutrition: Hydration and nutrition (e.g., suitable snacks) is provided to prevent weight loss for residents who wander and may not stay seated during meals. These theories provide insight into supporting safe wandering, leading to improved wellbeing for both residents and staff, enhanced safety and autonomy for residents, and reduced staff anxiety.

Discussion

Strategies that create a supportive environment, provide physical assistance, and support hydration and nutrition enabled residents to wander safely. Identified strategies improved wellbeing for both residents and staff. However, the same strategies also led to ethical concerns around digital monitoring, deception, and access restrictions.
