Hoe denken ouderen over automatische contactloze monitoring? Een systematische literatuurstudie

INTRODUCTION Technologies for contactless monitoring are increasingly used in order to contribute to qualitative and cost-effective care for older persons. The purpose of this systematic literature review is to explore the attitudes and perceptions of older persons towards the use of systems for contactless monitoring. METHODOLOGY Relevant studies were identified through an extensive search strategy in Medline, Embase and Cinahl for studies published between January 1990 and August 19 2012; using a reference list offered by a group of experts in this field of research and through the exploration of the reference lists of all relevant studies. RESULTS Nine studies with a qualitative study design and one study with a combined study design were included in this literature review. Various aspects of the attitudes, perceptions and needs of older persons as potential or actual end-users of contactless monitoring are discussed in five themes. This refers to the perceptions of older persons on the potential usefulness of contactless monitoring, the communication of information obtained through monitoring, several concerns when contactless monitoring is used and the participation and involvement of the person who is monitored. All these facets can influence the willingness of older people to accept these monitoring systems. CONCLUSIONS This review can offer technology developers and care providers useful information to promote acceptance and successful integration of systems for contactless monitoring into daily practice by ensuring that they meet the needs, concerns and wishes of older persons as their end-users. Further exploration of the attitudes and perceptions of older people towards contactless monitoring through qualitative and quantitative research with a good methodological quality is required.

Automated in-home gait transfer time analysis using video cameras

Previous studies have shown that gait speed is an important measure of functional ability in the elderly. Continuous monitoring of the gait speed of older adults in their home environment may therefore allow the detection of changes in gait speed which could be predictive of health changes of the monitored person. In this study, a system consisting of multiple wall-mounted cameras that can automatically measure the time an older adult needs to cross a predefined transfer zone in the home environment is presented. The purpose of this study is the preliminary validation of the algorithm of the camera system which consists of several preprocessing steps and the automatic measurement of the transfer times. This validation is done through data collection in the homes of four older adults for periods varying from eight to twelve weeks. Trends in the measured transfer times are visualised and subsequently compared with the results of clinical assessments obtained during the acquisition period such as Timed-Get-Up-and-Go tests. The results indicate that it is possible to identify long-term trends in transfer times which can be indicative of adverse health-related events.

P146: Attitudes and perceptions of adults of 60 years and older towards in-home monitoring of the activities of daily living with contactless sensors: an explorative study

Background and objectives: Contactless monitoring is increasingly used to enhance qualitative and cost-effective care for older persons. Succesful integration of this technology in older peoples’ daily lives, depends on their acceptance of these systems. The primary purpose was to explore attitudes and perceptions of adults of 60 years and older towards contactless monitoring of the activities of daily living. Design, participants and methods: A questionnaire was developed, validated and used in a cross-sectional survey with a convenience sample (n = 245). The results were presented using descriptive statistics and bivariate analyses to explore variables associated with willingness to install the technology. Results: Descriptive statistics indicate that adults of 60 years and older find contactless monitoring useful for various purposes (e.g. to remain living at home longer, safely and independently; for timely detection of emergency situations and gradually emerging health problems). They agree to share collected information with professional caregivers and own access to the data is valued. Respondents like to take part in diverse decisions about the monitoring (e.g. about the rooms in which it is installed, the type of sensors used and access of third parties to collected information). However, several concerns were expressed related to the functioning and financing of contactless monitoring. Bivariate analyses show that both socio-demographic factors (e.g. age, receiving professional home care) and attitudes and perceptions towards contactless monitoring (e.g. on its potential usefulness, on the availability of collected information, on the functional requirements and financial costs of the system and on the use of video cameras) can promote or impede acceptance of the technology. Conclusions: This explorative study indicates that older adults are willing to incorporate contactless monitoring in later life or when their health declines. They agree to share collected information with professional caregivers and clearly demand for participation in decisions about the technology. Various concerns and requirements provide implications for clinical practice and future research. Thereby, technology developpers, policy makers and professional caregivers can promote the implementation of contactless monitoring in the care for older adults. 2014 Elsevier Ltd.
