Existing video surveillance systems in long-term care facilities can be used to monitor such behaviours of risk to alert the staf to prevent potential injuries or death in some cases. However, these behaviours of risk events are heterogeneous and infrequent in comparison to normal events. Moreover, analysing raw videos can also raise privacy concerns.
Purpose: In this paper, we present two novel privacy-protecting video-based anomaly detection approaches to detect behaviours of risks in people with dementia.
Methods: We either extracted body pose information as skeletons or used semantic segmentation masks to replace multiple humans in the scene with their semantic boundaries. Our work difers from most existing approaches for video anomaly detection that focus on appearance-based features, which can put the privacy of a person at risk and is also susceptible to pixel-based noise, including illumination and viewing direction. We used anonymized videos of normal activities to train customized spatiotemporal convolutional autoencoders and identify behaviours of risk as anomalies.
Results: We showed our results on a real-world study conducted in a dementia care unit with patients with dementia, containing approximately 21 h of normal activities data for training and 9 h of data containing normal and behaviours of risk events for testing. We compared our approaches with the original RGB videos and obtained a similar area under the receiver operating characteristic curve performance of 0.807 for the skeleton-based approach and 0.823 for the segmentation mask-based approach.
Conclusions: This is one of the frst studies to incorporate privacy for the detection of behaviours of risks in people with dementia. Our research opens up new avenues to reduce injuries in long-term care homes, improve the quality of life of residents, and design privacy-aware approaches for people living in the community KITE Research Institute at University Health Network, Toronto Rehab Institute, University Health Network | Scientific Excellence - Advancing Knowledge | 2023-01-21 | | | Artificial Intelligence in Geriatric Mental Health: Recent Advances in Clinical ResearchArtificial intelligence in geriatric mental health: Recent advances in clinical research .Abstract published in International Psychogeriatrics, Volume 33, Issue S1, October 2021, pp. 1

The aim of this study was to investigate the relationship between gait features extracted from repeated, frequent gait assessments and future falls in older people with dementia. We found that gait instability, and increased neuropsychiatric symptoms, and fall history were independently associated with falls in people with dementia Toronto Rehab Institute, The KITE Research Institute at University Health Network, KITE Research Institute at University Health Network | Scientific Excellence - Advancing Knowledge | 2019-07-24 | | | Using Kinect camera to quantify gait variables that can predict falls in older adults with dementiaOur study demonstrated that a gait monitoring system comprising of a single Kinect camera can successfully quantify and monitor gait stability and fall risk of older people with dementia which makes it feasible to be used in the clinical settings.

This technology has clinical applications for locating residents within a care unit and as a nurse call system, and can also be used to gather information about movement, location, and activity over time. RTLS thus provides health data to track markers of health and wellbeing and augment healthcare decisions. To date, no reviews have examined the potential use of RTLS data in caring for older adults with cognitive impairment living in a residential care setting.
Objective: This scoping review aims to explore the use of data from real-time locating systems (RTLS) technology to inform clinical measures and augment healthcare decision-making in the care of older adults with cognitive impairment who live in residential care settings.
Methods: Embase (Ovid), CINAHL (EBSCO), APA PsycINFO (Ovid) and IEEE Xplore databases were searched for published English-language articles that reported the results of studies that investigated RTLS technologies in persons aged 50 years or older with cognitive impairment who were living in a residential care setting. Included studies were summarized, compared and synthesized according to the study outcomes.
Results: A total of 27 studies were included. RTLS data were used to assess activity levels, characterization of wandering, cognition, social interaction, and to monitor a resident’s health and wellbeing. These RTLS-based measures were not consistently validated against clinical measurements or clinically important outcomes, and no studies have examined their effectiveness or impact on decision-making.
Conclusion: This scoping review describes how data from RTLS technology has been used to support clinical care of older adults with dementia. Research efforts have progressed from using the data to track activity levels to, most recently, using the data to inform clinical decision-making and as a predictor of delirium. Future studies are needed to validate RTLS-based health indices and examine how these indices can be used to inform decision-making.AWCRP-2020-02 Toronto Rehab Institute, University Health Network, University of Toronto, Toronto Rehab Institute/University of Toronto, KITE Research Institute at University Health Network | Scientific Excellence - Advancing Knowledge | 2022-11-10 | |
