Abstract:
Objective:To evaluate the self-assessed and proxy-assessed quality of life among disabled elderly individuals aged 60 and above in Chengdu,analyze the factors influencing these assessments,and assess the consistency between these two types of outcomes and the feasibility of proxy assessments.Methods:The quality of life for disabled elderly individuals is measured using the EQ-5D-5L for both self-assessments and proxy assessments.Consistency testing is conducted using weighted Kappa and Intraclass Correlation Coefficient(ICC).Univariate and differential analyses are performed with the Mann-Whitney/Wilcoxon and Kruskal-Wallis tests,respectively.The analysis of influencing factors employs generalized linear model regression.Results:The results of proxy assessments are slightly higher than those of self-assessments.The consistency between self-assessed and proxy-assessed health utility values and EQ-VAS scores is good(with ICC values exceeding 0.7),while the consistency across various dimensions is fair to moderate(with weighted Kappa values approximately between 0.4 and 0.5).The degree of disability,economic status,outdoor activities and sleep,the relationship between caregivers and the elderly,and whether caregivers possess relevant caregiving knowledge,all have a statistically significant impact on the quality of life of disabled elderly individuals and the differences between self-assessed and proxy-assessed outcomes(P＜0.05).Conclusion:The quality of life of disabled elderly individuals is significantly lower than that of the general population.It is essential to consider various related factors to enhance the quality of life for these individuals.The EQ-5D-5L proxy assessment results from their primary caregivers can serve as a supplement to the self-assessment results of disabled elderly individuals.However,individual dimensions should be applied with caution,taking into account the characteristics and individual differences of the evaluated population,types of proxies,and measurement tools used.
