Development of the comprehensive inpatient transfer tool: initial reliability and validity

A new patient transfer assessment scale for use in inpatient rehabilitation facilities (IRFs) is warranted to assess level of assistance, adaptations needed for success, and movement strategies. This study presents initial psychometric analyses for the Comprehensive Inpatient Transfer Tool (CITT). CITT items were developed through interdisciplinary team discussions. Interrater reliability was assessed between blinded pairs of raters administering the CITT for each subject on the same day. Intrarater reliability was assessed with one rater administering the CITT for each subject twice within the same day. Thirty-six subjects in an IRF completed the CITT four times during their rehabilitation stay; three times at admission and once at discharge. Intraclass correlations (mixed models) were used in reliability and minimal detectable change (MDC) analyses. Spearman correlations of CITT and CITT change scores with their respective Functional Independence Measure (FIM) and Inpatient Rehabilitation Facility - Patient Assessment Instrument (IRF-PAI) transfer scores were performed for concurrent validity. Responsiveness was assessed using paired t-tests on change scores. Interrater and intrarater reliability ranged from 0.90 to 0.98. Correlations between the CITT and FIM/IRF-PAI ranged from 0.6 to 0.8. The MDC for CITT was 7.11 pts. Differences between admission and discharge CITT were significant (P < 0.001). The CITT, developed by an interdisciplinary team, addresses limitations of existing transfer measures utilized in IRFs. The CITT demonstrated excellent inter and intrarater reliability. Concurrent validity demonstrated modest agreement between existing transfer measures and the CITT. The CITT is a reliable, useful scale for evaluating transfer skills in patients admitted to an IRF.
