| Objective: To evaluate the reliability, validity and advantage of the ICF Check list in elderly patients with chronic heart failure (CHF). Methods: One hundred and forty patients with CHF were recruited in this study. The health state of patients was assessed by the ICF Check-list, the 36-items short form health survey (SF-36) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). Reliability and validity of those scales were conducted to compare their clinical effects. The cut-off points of different age of the patients were evaluated by ROC curve. The characteristics of patients in different age groups were shown by the frequency of the ICF category. Results: The Cronbach’s α coefficients of the ICF Check-list were 0.933-0.906 and those for the population over the age of 75 were 0.962. The Cronbach’s α coefficients of the SF-36 were 0.904 0.906. Spearman correlation coefficients of the ICF Check-list were 0.411-0.944 (P<0.01), and its total score was also statistically significantly related to the SF-36 (r = 0.483 to 0.678, P=0.000). Areas under the ROC curve of the ICF Check-list and the SF-36 were 0.700-0.790 and 0.340-0.493 respectively, and the former boundary points have better sensitivity and specificity. There were various high frequency ICF categories in different age groups or dimensions. Relatively, in patients aged 60-74, b134 sleep function, d920 entertainment and leisure were the higher frequency categories. In patients over 75 years old, b440 respiratory function, d430 lifting and transporting objects, s440 respiratory structure and s110 brain structure category were the higher frequency categories. Conclusion: ICF Check-list has better reliability, validity and diagnostic value than the SF-36 and KCCQ. There are significant differences in the types of injury in different ages, and the clinical work should be targeted for evaluation and treatment in the future. |
