“…An IC tag was attached to each patient's shirt with adhesive tape so that it could be easily re‐attached after a change of clothing. When a patient with an IC tag moved under an antenna, the tag sent information regarding tag identification, time and place, which was received by the antenna …”

Aim: Although wandering is one of the major research focuses of the behavioural psychological symptoms of dementia, assessment of wandering has mostly relied on caregiver-administered questionnaires. The purpose of this study was to compare staff-administered Algase Wandering Scale outcomes with objective temporal and spatial movement indicators obtained from the Integrated Circuit (IC) tag monitoring system. Methods: Patients with dementia were recruited from a dementia care unit in Osaka, Japan in 2007. Primary nurses administered the Algase Wandering Scale, and the temporal and spatial movements of the subjects were monitored by the IC tag. Written informed consent was obtained from each subject's proxies. Results: Nurses' assessments of wandering were in agreement with the IC tag outcomes only during the day shift. Spatial movements assessed by the staff did not reflect those measured by the IC tag. Conclusion: This objective measurement of wandering showed the limitations in the assessment of spatial and temporal movement by the staff.

Background: Pharmacological and non-pharmacological approaches are commonly used to treat patients' institutionalised for nighttime wandering. Actigraphy and other scales have been used to evaluate the efficacy of these treatments. However, in clinical settings, nursing records are often the sole source of daily observation of nighttime wandering. Thus, physicians rely on nursing records to evaluate pharmacological and non-pharmacological treatments. This study examined nighttime movements of patients with dementia, comparing the results of integrated circuit tag monitoring with hourly nighttime nursing records. We tested which factors were associated with agreement rates between the two data sources. Methods: The study hospital was a general hospital in Osaka, Japan. Monitoring was conducted in a closed 60-bed dementia care unit. An integrated circuit tag monitoring system was used to monitor the movement of institutionalised dementia patients for over half a year. The distance moved per hour by subjects was measured using the monitoring system, and the data were compared with hourly nighttime nursing records. Agreement rates were calculated between the two data sources. Results: Thirty-five patients were monitored. Between 10-30% of subjects moved at any given hour during the night. The overall agreement rate between sources of movement data was 39%. Agreement rates were significantly correlated with the interquartile of the distance moved, changes in medication, physical conditions, and behavioural and psychological symptoms of dementia measured during the day. Conclusions: Although the agreement rate was low, staff appeared to pay more attention to patients associated with notable events during the day and patients exhibiting variability in distance moved.
