Abstract
Objective
To determine whether a multidimensional computerized adaptive test, the Functional
Assessment in Acute Care Multidimensional Computerized Adaptive Test (FAMCAT), could
be administered to hospitalized patients via a tablet computer rather than being orally
administered by an interviewer.
Design
A randomized comparison of the responses of hospitalized patients to interviewer vs
tablet delivery of the FAMCAT and its assessment of applied cognition, daily activity,
and basic mobility.
Setting
Two quaternary teaching hospitals in the Upper Midwest.
Participants
A total of 300 patients (127 men, 165 women), average age 61.2 (range, 18-97) hospitalized
on medical services or rehospitalized on surgical services were randomly assigned
to either a tablet (150) or an interview (150) group.
Intervention
Electronic tablet vs interview.
Main Outcome Measures
Item response theory point estimates of the FAMCAT latent scales, their psychometric
standard errors, number of items administered per domain, the determinant (an indicator
of overall precision of the latent trait vector), as well as the time that patients
required to complete their FAMCAT sessions.
Results
Of the 300 patients, 292 completed their assessments. The assessments of 4 individuals
in each group was interrupted by clinical care and were not included in the analyses.
A significant (P=.009) mode effect (ie, interview vs tablet) was identified when all outcome variables
were considered simultaneously. However, the only outcome that was affected by the
administration mode was test duration: tablet administration reduced the roughly 6-minute
test time required by both approaches by only 20 seconds, which, though statistically
significant, was clinically insignificant.
Conclusions
The results of a FAMCAT assessment, at least for this cohort of hospitalized patients,
are independent of administration via tablet computer or interview.
