- ItemDefining obtrusiveness in home telehealth technologies: a conceptual framework.(2006-07-24) Hensel, Brian K; Demiris, George; Courtney, Karen LThe literature of home telehealth technology recommends that systems be designed to minimize their obtrusiveness to end users However this term is neither explicitly defined nor consistently used This paper presents a definition of the concept of obtrusiveness Within this definition twenty two categories of what may be perceived as obtrusive in home telehealth technology are proposed based on a review of the literature These categories are grouped into eight dimensions This effort represents an initial step toward developing measures of obtrusiveness associated with home telehealth technology A validated and reliable instrument would allow for evaluation of individual applications as well as theory building across applications
- ItemEthical considerations for the utilization of tele-health technologies in home and hospice care by the nursing profession.(2006-02-01) Demiris, George; Oliver, Debra Parker; Courtney, Karen LHome care including hospice care is a growing component of the current healthcare system and pertains to care services that are provided to individuals their family members and caregivers in their own residence Both domains face funding limitations as life expectancy and the segment of the population older than 65 years increase Tele health defined as the use of advanced telecommunication technologies to enable communication between patients and healthcare providers separated by geographic distance is perceived as a concept that can enhance both home and hospice care and address some of the current challenges This article discusses ethical challenges associated with the utilization of tele health technologies by the nursing profession in the home setting These factors form a framework for the ethical considerations that result from the introduction of these technologies in nursing practice Specifically the article discusses the issue of privacy and confidentiality of patient data informed consent equity of access promoting dependency versus independence the lack of human touch and the impact of technology on the nurse patient relationship and the medicalization of the home environment These issues constitute a road map both for nursing practitioners who are aiming to provide an efficient delivery of services in the home and for nursing administrators who are asked to make judgments about the use of tele health technology as a supplement to traditional care and as a cost saving tool
- ItemFactors to weigh when considering electronic data collection.(2005-11-04) Courtney, Karen L; Craven, Catherine KResearchers are increasingly considering the adoption of electronic data collection methods which entail the use of the Web e mail and desktop and handheld computers for surveys diaries research instruments and focus groups Based on prior research findings on electronic data collection the authors delineate the key factors which incorporate population data and resource characteristics that guide researchers in selecting the data collection method most appropriate for their research question Population factors to consider in data collection decisions are age gender socio economic status and access to technology Key data factors influencing the selection of collection method include sensitivity of the topic time sensitivity longitudinal data and contextual data Data collection decisions are also based on financial time and technological resources Technology and demographics will continue to change and affect data collection methods and possibilities By examining these key factors however researchers will be able to reach data collection decisions that are appropriate for each project
- ItemInformation technology: changing nursing processes at the point-of-care.(2005-11-01) Courtney, Karen L; Demiris, George; Alexander, Greg LChanging societal demographics increasing complexity in healthcare knowledge and increasing nursing shortages have led healthcare strategists to call for a redesign of the healthcare system Embedded within most redesign recommendations is the increased use of technology to make nursing practice more efficient However information technology IT has the potential to go beyond simple efficiency increases If IT is perceived truly as a part of the redesign of healthcare delivery rather than simply the automation of existing processes then it can change nursing processes within institutions and furthermore change the point of care between nurses and patients Nursing adoption of technology within the workplace is a result of the interactions between technical skills social acceptance and workplace culture Nursing needs for information not only influence their adoption of particular technologies but also shape their design The objective of this article is to illustrate how IT can change not only nursing practice and processes but also the point of care A case study of the use of IT by nurses in telehomecare is presented and administrative implications are discussed
- ItemObtrusiveness of information-based assistive technologies as perceived by older adults in residential care facilities: a secondary analysis.(2007-08-16) Courtney, Karen L; Demiris, George; Hensel, Brian KWith the anticipated growth in the older adult population in the next few years information designers are examining new ways for assistive technologies to support independent living and quality of life for adults as they age Central to the role of assistive technology to support and enhance quality of life is the development of non obtrusive technologies Despite the importance of non obtrusiveness to the design of assistive technologies there remains no standard definition of obtrusiveness or measurement instrument A conceptual framework for obtrusiveness in home telehealth technologies has recently been proposed but has not yet been tested empirically This project performed a secondary analysis of focus group and interview data to explore the presence of the dimensions of the obtrusiveness framework in older adults responses to information based assistive technologies in residential care facilities We found the existing data contained examples of each dimension physical usability privacy function human interaction self concept routine and sustainability and 16 of the 22 subcategories proposed by the obtrusiveness framework These results provide general support for the framework although further prospective validation research is needed Potential enhancements to the framework are proposed
- ItemPatient-centered applications: use of information technology to promote disease management and wellness. A white paper by the AMIA knowledge in motion working group.(2007-12-14) Demiris, George; Afrin, Lawrence B; Speedie, Stuart; Courtney, Karen L; Sondhi, Manu; Vimarlund, Vivian; Lovis, Christian; Goossen, William; Lynch, CecilAdvances in information technology IT enable a fundamental redesign of health care processes based on the use and integration of electronic communication at all levels New communication technologies can support a transition from institution centric to patient centric applications This white paper defines key principles and challenges for designers policy makers and evaluators of patient centered technologies for disease management and prevention It reviews current and emerging trends highlights challenges related to design evaluation reimbursement and usability and reaches conclusions for next steps that will advance the domain
- ItemUse of technology as a support mechanism for caregivers of hospice patients.(2006-02-17) Demiris, George; Parker Oliver, Debra R; Courtney, Karen L; Porock, Davina
