This investigation examined the ability of a four-item Health-Related Quality of Life (HRQOL) scale to predict short-term (30-day) and long-term (1-year) physician visits, hospitalization, and mortality among older adults.
Subjects included 84065 individuals aged 65 and older who completed a mail version of the Centers for Diseases Control's Behavioral Risk Factor Surveillance System (BRFSS) Core HRQOL Module. HRQOL dimensions represented by the module include global self-rated general health, recent physical health, recent mental health, and recent activity limitation.
In analysis of covariance models controlling for demographic factors and comorbidity, the number of physician visits within 30 days and 1 year differed significantly across categories of each HRQOL item. In Cox regression models controlling for the same covariates, all four HRQOL questions were significant predictors of 30-day and 1-year hospitalization and mortality.
These results signify that all four dimensions of HRQOL represented by the BRFSS Core HRQOL Module are important predictors of both short-term and long-term adverse health events among older adults. This brief scale may be particularly useful for assessing the health of older adults in clinical settings and large-scale epidemiological studies.
本研究调查了一个包含四项内容的健康相关生活质量（HRQOL）量表预测老年人短期（30天）和长期（1年）看医生、住院及死亡情况的能力。
研究对象包括84065名65岁及以上的老年人，他们完成了疾病控制中心行为危险因素监测系统（BRFSS）核心HRQOL模块的邮寄版。该模块所代表的HRQOL维度包括总体自我评定的一般健康状况、近期身体健康状况、近期心理健康状况以及近期活动受限情况。
在控制了人口统计学因素和合并症的协方差分析模型中，30天内和1年内看医生的次数在每个HRQOL项目的类别之间存在显著差异。在控制了相同协变量的Cox回归模型中，所有四个HRQOL问题都是30天和1年住院及死亡情况的显著预测因素。
这些结果表明，BRFSS核心HRQOL模块所代表的HRQOL的所有四个维度都是老年人短期和长期不良健康事件的重要预测因素。这个简短的量表对于在临床环境和大规模流行病学研究中评估老年人的健康状况可能特别有用。
