Primary objective: The study aim is to explore the perceptions and expectations of seniors in regard to ‘smart home’ technology installed and operated in their homes with the purpose of improving their quality of life and/or monitoring their health status. Research design and methods: Three focus group sessions were conducted within this pilot study to assess older adults' perceptions of the technology and ways they believe technology can improve their daily lives. Themes discussed in these groups included participants' perceptions of the usefulness of devices and sensors in health-related issues such as preventing or detecting falls, assisting with visual or hearing impairments, improving mobility, reducing isolation, managing medications, and monitoring of physiological parameters. The audiotapes were transcribed and a content analysis was performed. Results: A total of 15 older adults participated in three focus group sessions. Areas where advanced technologies would benefit older adult residents included emergency help, prevention and detection of falls, monitoring of physiological parameters, etc. Concerns were expressed about the user-friendliness of the devices, lack of human response and the need for training tailored to older learners. Conclusions: All participants had an overall positive attitude towards devices and sensors that can be installed in their homes in order to enhance their lives.

The purpose of this study was to describe prevalence of technology use among adults ages 65 and older, particularly for those with disability and activity-limiting symptoms and impairments. Data from the 2011 National Health and Aging Trends Study, a nationally representative sample of community-dwelling Medicare beneficiaries (N = 7,609), were analyzed. Analysis consisted of technology use (use of e-mail/text messages and the internet) by sociodemographic and health characteristics and prevalence ratios for technology usage by disability status. Forty percent of older adults used e-mail or text messaging and 42.7% used the internet. Higher prevalence of technology use was associated with younger age, male sex, white race, higher education level, and being married (all p values <.001). After adjustment for sociodemographic and health characteristics, technology use decreased significantly with greater limitations in physical capacity and greater disability. Vision impairment and memory limitations were also associated with lower likelihood of technology use. Technology usage in U.S. older adults varied significantly by sociodemographic and health status. Prevalence of technology use differed by the type of disability and activity-limiting impairments. The internet, e-mail, and text messaging might be viable mediums for health promotion and communication, particularly for younger cohorts of older adults and those with certain types of impairment and less severe disability.

We conducted a systematic review of studies employing telehealth interventions which focused on family caregivers’ outcomes. The Embase, CINHAL, Cochrane and PubMed databases were searched using combinations of keywords including “telehealth,” “telemedicine,” “telecare,” “telemonitoring,” “caregiver” and “family.” The initial search produced 4205 articles, of which 65 articles met the inclusion criteria. The articles included 52 experimental studies, 11 evaluation studies, one case study and one secondary analysis. Thirty-three articles focused on family caregivers of adult and older patients, while 32 articles focused on parental caregivers of paediatric patients. The technologies included video, web-based, telephone-based and telemetry/remote monitoring. Six main categories of interventions were delivered via technology: education, consultation (including decision support), psychosocial/cognitive behavioural therapy (including problem solving training), social support, data collection and monitoring, and clinical care delivery. More than 95% of the studies reported significant improvements in the caregivers’ outcomes and that caregivers were satisfied and comfortable with telehealth. The review showed that telehealth can positively affect chronic disease care, home and hospice care.

Objectives: The goal of meeting the desire of older adults to remain independent in their home setting while controlling healthcare costs has led to the conceptualization of “smart homes.” A smart home is a residence equipped with technology that enhances safety of residents and monitors their health conditions. The study aim is to assess older adults’ perceptions of specific smart home technologies (i.e., a bed sensor, gait monitor, stove sensor, motion sensor, and video sensor). Methods: The study setting is TigerPlace, a retirement community designed according to the Aging in Place model. Focus group sessions with fourteen residents were conducted to assess perceived advantages and concerns associated with specific applications, and preferences for recipients of sensor-generated information pertaining to residents’ activity levels, sleep patterns and potential emergencies. Sessions were audio-taped; tapes were transcribed, and a content analysis was performed. Results: A total of fourteen older adults over the age of 65 participated in three focus group sessions Most applications were perceived as useful, and participants would agree to their installation in their own home. Preference for specific sensors related to sensors’ appearance and residents’ own level of frailty and perceived need. Specific concerns about privacy were raised. Conclusions: The findings indicate an overall positive attitude toward sensor technologies for nonobtrusive monitoring. Researchers and practitioners are called upon to address ethical and technical challenges in this emerging domain.

Summary: Objectives A “smart home” is a residence wired with technology features that monitor the well-being and activities of their residents to improve overall quality of life, increase independence and prevent emergencies. This type of informatics applications targeting older adults, people with disabilities or the general population is increasingly becoming the focus of research worldwide. The aim of this study was to provide a comprehensive review of health related smart home projects and discuss human factors and other challenges. MethodsTo cover not only the medical but also the social sciences and electronics literature, we conducted extensive searches across disciplines (e.g., Medline , Embase , CINAHL, PsycINFO, Electronics and Communications Abstracts, Web of Science etc.). In order to be inclusive of all new initiatives and efforts in this area given the innovativeness of the concept, we manually searched for relevant references in the retrieved articles as well as published books on smart homes and gerontechnology Results A total of 114 publications (including papers, abstracts and web pages) were identified and reviewed to identify the overarching projects. Twenty one smart home projects were identified (71% of the projects include technologies for functional monitoring, 67% for safety monitoring, 47% for physiological monitoring, 43% for cognitive support or sensory aids, 19% for monitoring security and 19% to increase social interaction). Evidence for their impact on clinical outcomes is lacking. Conclusions The field of smart homes is a growing informatics domain. Several challenges including not only technical but also ethical ones need to be addressed.
