Development of a telemedicine protocol for the diagnosis of Alzheimer's disease.

We developed a telemedicine protocol for diagnosis of Alzheimer's Disease (AD). Assessments by video-conferencing (remote) were compared with face to face (direct) assessments. Eight physicians performed direct assessments and two physicians conducted remote assessments. There was alternate allocation of direct or remote initial assessment. The participants were 20 subjects over 65 years living in a rural area and referred by general practitioners (GPs) because of cognitive impairment. Each assessment included a Standardised Mini Mental State Examination, Geriatric Depression Scale, Katz assessment of Activities of Daily Living, Instrumental ADL assessment, and the Informant Questionnaire for Cognitive Decline in the Elderly. Laboratory results and radiological imaging were available from referring GPs. There was good agreement for diagnosing Alzheimer's disease between telemedicine and direct assessment, kappa = 0.8 (P<0.0001). However, because of the small sample size, the presence of systematic bias could not be completely excluded. We conclude that it is possible to diagnose AD at a distance using telemedicine, but this requires validation with a larger study.

A pilot randomized controlled trial of deprescribing.

OBJECTIVE: Polypharmacy and adverse drug reactions are frequent and important among older people. Few clinical trials have evaluated systematic withdrawal of medications among older people. This small, open, study was conducted to determine the feasibility of a randomized controlled deprescribing trial. METHODS: Ten volunteers living in the community (recruited by media advertising) and 25 volunteers living in residential aged-care facilities (RCFs) were randomized to intervention or control groups. The intervention was gradual withdrawal of one target medication. The primary outcome was the number of intervention participants in whom medication withdrawal could be achieved. Other outcomes measures were quality of life, medication adherence, sleep quality, and cognitive impairment. RESULTS: Participants were aged 80 ± 11 years and were taking 9 ± 2 medications. Fifteen participants commenced medication withdrawal and all ceased or reduced the dose of their target medication. Two subjects withdrew; one was referred for clinical review, and one participant declined further dose reductions. CONCLUSIONS: A randomized controlled trial of deprescribing was acceptable to participants. Recruitment in RCFs is feasible. Definitive trials of deprescribing are required.

Attitudes toward information and communication technology (ICT) in residential aged care in Western Australia.

OBJECTIVES: Determine why introduction of health consulting services via Telehealth video conference consultations failed in residential aged care facilities (RACF). DESIGN: Semistructured interview groups and quantitative survey. SETTING: Two participating not-for-profit RACF. PARTICIPANTS: Managers, employed carers, physiotherapist, occupational therapist, registered nurses, and residents from RACF. MEASUREMENTS: A survey initially followed by focus groups that centered on 4 questions. How can computers help improve care? What kind of electronic services and products could help improve care? Who should have access to the technology and why was the technology not used? RESULTS: The survey revealed there was awareness of information and communication technology (ICT) in RACF. However, respondents were uncertain of potential benefits provided to their clients. Only 43% of respondents thought a minority of clients would receive the benefits of ICT use. The focus groups revealed several themes regarding the attitudes toward ICT in RACF. Positive attitudes to ICT included themes of saving time, easier doctor access, cost saving, and improved communications. Negative attitudes included themes of loss of human contact, inadequate training, security barriers, not user friendly, limited ability to comply with suggestions, privacy issues, and capital cost. Residents were also concerned about confidentiality and loss of human interaction with the use of Telehealth in residential aged facilities. CONCLUSIONS: More training for staff is required to enable them to use ICT efficiently. ICT hardware and software at the user interface must be designed to maintain confidentiality with ease of access. Access to Telehealth services should not impede the routine delivery of personal care and human contact for residents. Studies are required as to where human input to residents is unable to be replaced by Telehealth services.
