Feasibility study of the integrated circuit tag monitoring system for dementia residents in Japan.
ABSTRACT Videotaping, direct observation, and biomechanical devices have been used to measure the wandering behavior of institutionalized people with dementia and to identify patterns of movement. Owing to technical limitations, the variability in movement patterns or the distance traveled could not be examined. The present study examined the feasibility of an integrated circuit tag monitoring system to monitor the movement patterns of Japanese dementia residents. This system generated the following data: the frequency of detection by each receiver, the duration of stay in each location, the cumulative distance walked per day, and the graphic display of the movement pattern. This new system offers objective measurements of ambulation in time and space, which can be used to characterize demented patients and to evaluate the effects of treatment and care.

ABSTRACT: In this paper, published research studies addressing the phenomenon of wandering in dementia are reviewed. Empirical findings of 108 studies are categorized and summarized to reveal dimensions of wandering behavior, significance of wandering as a clinical phenomenon, correlates of wandering, and tested intervention strategies. Implications for improving methodological rigor of future studies are offered and gaps in the current knowledge base are identified.Annual review of nursing research 02/1999; 17:185-217.

ABSTRACT: Behavioural problems are an important feature of dementia and other neuropsychiatric conditions. This paper describes the development and performance of an investigator-based interview (the PBE) for the detailed assessment of the behaviour of subjects over the preceding four weeks. The interview is designed to be administered to carers. A test-retest reliability study was carried out on the penultimate edition of this interview; and the inter-rater reliability of the final edition was measured. These studies show that the reliability of the PBE is comparable with that of other investigator-based interviews.Psychological Medicine 03/1992; 22(1):223-30. · 5.59 Impact Factor

ABSTRACT: We developed a new instrument, the Neuropsychiatric Inventory (NPI), to assess 10 behavioral disturbances occurring in dementia patients: delusions, hallucinations, dysphoria, anxiety, agitation/aggression, euphoria, disinhibition, irritability/lability, apathy, and aberrant motor activity. The NPI uses a screening strategy to minimize administration time, examining and scoring only those behavioral domains with positive responses to screening questions. Both the frequency and the severity of each behavior are determined. Information for the NPI is obtained from a caregiver familiar with the patient's behavior. Studies reported here demonstrate the content and concurrent validity as well as between-rater, test-retest, and internal consistency reliability; the instrument is both valid and reliable. The NPI has the advantages of evaluating a wider range of psychopathology than existing instruments, soliciting information that may distinguish among different etiologies of dementia, differentiating between severity and frequency of behavioral changes, and minimizing administration time.Neurology 01/1995; 44(12):2308-14. · 8.25 Impact Factor
