Abstract
Objective
To develop a system to guide interpretation of scores generated from the newly developed
item response theory (IRT)-based Functional Assessment in Acute Care Multidimensional
Computerized Adaptive Test (FAMCAT), which assesses 3 important domains of function:
Mobility, Daily Activities, and Applied Cognition.
Design
Cross-sectional data was used to inform a modified Delphi approach to establish FAMCAT
cutpoints delineating various functional ability levels.
Setting
Large midwestern academic teaching hospital.
Participants
Patients hospitalized to an inpatient medical service (N=2049).
Interventions
Not applicable.
Main Outcome Measures
FAMCAT Basic Mobility, Daily Activity, and Applied Cognition scores.
Results
IRT-based score estimation data was successfully integrated with expert clinical feedback
using a modified Delphi process to arrive at consensus yielding 4 functional level
strata (ranging from bed-based mobility to independent mobility) for both the FAMCAT
Mobility and Daily Activity scales; 1 cutpoint was supported to delineate 2 functional
strata for Applied Cognition.
Conclusions
Meaningful cutpoints were established for each FAMCAT domain using a data-informed,
modified Delphi process for achieving consensus. The resulting FAMCAT interpretation
guide may be used to develop an ability-matched mobility preservation program and
identify patients who may require a higher level of supervision based on the resulting
FAMCAT scores.
