在老年门诊人群中对Karnofsky行为量表（KPS）进行了以下三个方面的评价：其与广泛使用和验证的老年仪器的关联强度;其预测患者结局的能力;以及其作为高风险患者识别符的能力。134例患者样本进行了全面的老年评估，其中包括KPS，日常生活活动（ADL）量表，工具性日常生活活动（IADL）量表，以及其他心理和感觉测试。KPS、ADL和IADL之间存在显著相关性，KPS与其他功能指标的相关性最强。KPS对结果也具有高度预测性，表现更好或与ADL和IADL相当。高风险组和低风险组的KPS指定导致在统计学上显着的得分差异组之间的所有，但一个评估领域，表现出更好的能力比ADL或IADL的区分。因此，KPS被证明可以作为患者健康和功能状态的有效替代评分。它也是住院、生存时间、社区居住和机构化的重要预测因素。最后，KPS被证明能够充分区分风险群体，以帮助针对门诊老年患者提供服务。
The Karnofsky Performance Scale (KPS) was evaluated in a geriatric outpatient population with regard to three issues: its strength of association with widely used and validated geriatric instruments; its ability to predict patient outcomes; and its ability to serve as an identifier of high-risk patients. The 134-patient sample was given a comprehensive geriatric assessment which included the KPS, the Activities of Daily Living (ADL) scale, the Instrumental Activities of Daily Living (IADL) scale, and other psychosocial and sensory tests. The KPS, ADL, and IADL were significantly correlated with each other, and the KPS showed the strongest associations with other functional measures. The KPS was also highly predictive of outcomes, performing better or equally well as the ADL and IADL. The KPS designation of high- and low-risk groups resulted in statistically significant score differences between groups in all but one assessment area, demonstrating better ability to discriminate than either the ADL or IADL. Thus, the KPS was shown to serve as an effective proxy score for a patient's health and functional status. It also was a significant predictor of hospitalizations, survival time, community residence, and institutionalization. Finally, the KPS was shown to adequately distinguish risk groups to aid in the targeting of services to ambulatory geriatric patients.
