Population

200 patients discharged from the hospital

Comparison

Computerized adaptive testing based 18-item… vs Nonadaptive testing (NAT)

Design

Cross-sectional

Follow-up

at discharge

Overview

CAT may reduce survey burden for hospitalized patients; leaves open prospective validation for response rates and clinical utility.

Structured PICO

Does computerized adaptive testing (CAT) improve efficiency without compromising precision compared to nonadaptive testing (NAT) in assessing patient perception of hospitalization?

P
Population
200 patients discharged from the hospital
I
Intervention
Computerized adaptive testing (CAT) based 18-item inpatient perception questionnaire administered on wireless computers on wheels (COW)
C
Comparator
Nonadaptive testing (NAT)
O
Outcome
Relative efficiency (number of questions administered) and precision of measures of patient perceptionspatient reported

Computerized adaptive testing for patient perception surveys reduces the number of questions by 42% without compromising measurement precision.
