To date, there is no validated telephone version of the Kansas City Cardiomyopathy Questionnaire (KCCQ) available to collect data about health-related quality of life among patients with heart failure (HF). We assessed the reliability of the German KCCQ administered via telephone in comparison to the self-administered version. Patients with HF admitted to the outpatient clinic of the University Hospital Würzburg were consecutively identified and recruited. Patients completed (a) the self-administered version of the KCCQ, and (b) the telephone-based interview performed by trained raters. The sequence of both approaches was randomized. For the between-method agreement, the intraclass correlation coefficient (ICC) was calculated using a non-parametric, rank-based approach. We analysed data from sixty-one HF patients. The median KCCQ overall summary score was 84.8 (interquartile range (IQR) 71.6-76.9). The test-retest reliability between the self-administered and the telephone interview showed good agreement for the total symptom score, the clinical score and the overall summary core: ICC 0.75, 95 % confidence interval (CI) 0.72-0.79; ICC 0.80, CI 0.77-0.84; ICC 0.83, CI 0.80-0.86, respectively. The German KCCQ administered via telephone showed good test-retest reliability, indicating its applicability to collect data about health status among HF patients over the phone.
迄今为止，尚无经过验证的堪萨斯城心肌病问卷（KCCQ）电话版本可用于收集心力衰竭（HF）患者与健康相关的生活质量数据。我们评估了通过电话方式进行的德语版KCCQ与自行填写版本相比的可靠性。连续识别并招募了维尔茨堡大学医院门诊收治的HF患者。患者完成了（a）KCCQ自行填写版本，以及（b）由经过培训的评估人员进行的电话访谈。两种方式的顺序是随机的。对于方法间一致性，使用非参数、基于秩的方法计算组内相关系数（ICC）。我们分析了61例HF患者的数据。KCCQ总体总结得分的中位数为84.8（四分位间距（IQR）71.6 - 76.9）。自行填写和电话访谈之间的重测信度在总症状得分、临床得分和总体总结核心方面显示出良好的一致性：ICC分别为0.75，95%置信区间（CI）0.72 - 0.79；ICC 0.80，CI 0.77 - 0.84；ICC 0.83，CI 0.80 - 0.86。通过电话方式进行的德语版KCCQ显示出良好的重测信度，表明其适用于通过电话收集HF患者的健康状况数据。
