The G8 is a widely used frailty screening tool in patients with cancer that was designed to be completed by healthcare professionals. A patient-reported version would enable a broader application. Aim of this study was to develop a self-reported version of the G8 and to assess its agreement with the original G8.
A self-reported version of the G8 was developed with the aid of communication specialists. Patients aged ≥ 70 years from two different study populations were included: 1. Patients with cancer and 2. Patients visiting the geriatric outpatient clinic. The original G8 was completed by an oncology nurse or clinical research assistant and patients completed the self-reported G8. Patients were blinded to results of the original G8. Kappas were calculated to measure the agreement between the self-reported and original G8 for both the individual items as well as for the cut-off for potential frailty (≤14).
161 patients participated, of whom 104 had cancer (65%). Patients with cancer more frequently completed all items than geriatric patients (all items completed in 94% versus 72%, p < 0.001). The agreement for potential frailty was substantial for patients with cancer (Kappa 0.63) and poor for geriatric patients (Kappa 0.05).
Completion of the self-reported G8 is feasible and agreement of its outcome with the original G8 outcome is sufficient for patients with cancer but not for geriatric patients. The self-reported G8 may therefore be a useful alternative to the original G8 in older patients with cancer.
G8 是一种广泛应用于癌症患者的衰弱筛查工具，旨在由医疗保健专业人员完成。患者报告版本将能够更广泛地应用。本研究旨在开发 G8 的自评版本，并评估其与原始 G8 的一致性。
在沟通专家的帮助下，开发了 G8 的自评版本。纳入了来自两个不同研究人群的年龄≥70 岁的患者：1. 癌症患者和 2. 老年门诊就诊患者。由肿瘤护士或临床研究助理完成原始 G8，患者完成自评 G8。患者对原始 G8 的结果不知情。计算 Kappa 值以衡量自评 G8 和原始 G8 在单个项目以及潜在衰弱的截止值（≤14）之间的一致性。
共有 161 名患者参与，其中 104 名患有癌症（65%）。癌症患者比老年患者更频繁地完成所有项目（所有项目完成率为 94%比 72%，p<0.001）。癌症患者的潜在衰弱的一致性较高（Kappa 值为 0.63），而老年患者的一致性较差（Kappa 值为 0.05）。
自评 G8 的完成是可行的，其结果与原始 G8 结果的一致性对于癌症患者是足够的，但对于老年患者则不然。因此，自评 G8 可能是老年癌症患者替代原始 G8 的有用工具。
