INPATIENT
To determine the effects of a
way-finding intervention on
residents’ ability to find their
way in a new environment.
RCT
N=32
Intervention
Backward chaining rehearsal
of way-finding and use of an
individualized location map
Control
no intervention
Outcome Measures
Agitation, spatial orientation,
ability to find way to dining
room and bedroom
More residents in the intervention
group were able to
find their way to the dining
room compared with the
control group, but this was
not sustained at follow-up.
No differences were found
between groups in finding
their way to their bedrooms.
Both groups had decreased
agitation. Spatial orientation
scores were low for both
groups.
A possible attention bias may
have favoured the intervention
group. Despite sample
size calculation, a larger sample
would have been helpful
for further analyses.
RCT = randomized controlled trial.
