System-wide Clinical Assessment of Functioning Based on the International Classification of Functioning, Disability and Health in China: Interrater Reliability, Convergent, Known Group, and Predictive Validity of the ICF Generic-6

  • Objective To validate the International Classification of Functioning, Disability and Health (ICF) Generic-6 in daily routine clinical practice in Mainland China. Specific objectives were to analyze (1) interrater reliability, (2) convergent validity, (3) known group validity, and (4) predictive validity of the ICF Generic-6. Design Multicenter prospective cohort study. Setting Fifty hospitals from 20 provinces of Mainland China. Participants A total of 4510 patients from departments of rehabilitation, orthopedics, neurology, cardiology, pneumology, and cerebral surgery of the participating hospitals with different health conditions were included in this study. Intervention Not applicable. Main Outcome Measures The assessment was undertaken by nurses with ICF Generic-6 in combination with a numeric rating scale. Interrater reliability was evaluated with intraclass correlation coefficients (ICC). Convergent validity was evaluated with Spearman correlation coefficients between ICF Generic-6 and Medical Outcomes Short Form (SF)-12 items. Known group validity was examined by comparing discharge scores between different discharge destinations. Predictive validity was determined by using ICF Generic-6 baseline scores for estimating length of hospital stay with a loglogistic survival model with gamma shared frailty and cost of in-hospital treatment with a mixed effects generalized linear regression model of the gamma family. Results The interrater reliability of items and score of ICF Generic-6 was good with ICCs ranging from 0.67-0.87. ICF Generic-6 items were further correlated with respective SF-12 items. Discharge scores of patients differed significantly by discharge destination. The ICF Generic-6 admission score was a significant predictor of length of stay and treatment cost. Conclusions The ICF Generic-6 administered in combination with a 0-10 numeric rating scale is a reliable and valid tool for the collection of minimal information on functioning across various clinical settings.
