呼吸困难是心肺和神经肌肉疾病的一种常见的令人痛苦的症状，它被定义为“一种呼吸不适的主观体验，由不同强度的不同质量的感觉组成。”然而，日本重症监护病房（icu）没有常规筛查呼吸困难，因为没有经过验证的日本版呼吸窘迫观察量表（RDOS）可用。因此，我们的目的是将该问卷的英文版本翻译成日语，并评估其效度和信度。为了翻译RDOS，我们在一家综合性医院的12个床位的ICU进行了一项前瞻性观察研究，其中包括42名医疗保健专业人员，10个专家组和128名通气患者。英语版本被翻译成日语，并对医疗保健专业人员进行了几份基于网络的横断面问卷调查。完成翻译过程后，对通气患者进行效度和信度评估。评估者间信度采用科恩加权卡帕系数。根据RDOS与呼吸困难视觉模拟量表的相关性确定标准效度。使用受试者工作特征曲线下面积分析来评估RDOS识别自我报告的呼吸困难患者的能力。量表水平上的平均内容效度指数为0.95。收集并分析了128例患者的数据。两个量表的科恩加权kappa系数和相关系数分别为0.76和0.443（95%置信区间分别为0.70-0.82和0.23-0.62）。对于预测自我报告的呼吸困难，受试者工作特征曲线下面积为0.81（95%可信区间为0.67-0.97）。使用的最佳截止值为1，敏感性和特异性分别为0.89和0.61。我们的研究结果表明，日本版的RDOS在轻度镇静机械通气患者的面部效度、可理解性、标准效度和评分间信度方面是可以接受的，表明其临床实用性。
Dyspnea is a common, distressing symptom of cardiopulmonary and neuromuscular diseases and is defined as “a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity.” However, Japanese intensive care units (ICUs) do not routinely screen for dyspnea, as no validated Japanese version of the Respiratory Distress Observation Scale (RDOS) is available. Therefore, we aimed to translate the English version of this questionnaire into Japanese and assess its validity and reliability. To translate the RDOS, we conducted a prospective observational study in a 12-bed ICU of a universal hospital that included 42 healthcare professionals, 10 expert panels, and 128 ventilated patients. The English version was translated into Japanese, and several cross-sectional web-based questionnaires were administered to the healthcare professionals. After completing the translation process, a validity and reliability evaluation was performed in the ventilated patients. Inter-rater reliability was evaluated using Cohen’s weighted kappa coefficient. Criterion validity was ascertained based on the correlation between RDOS and the dyspnea visual analog scale. The area under the receiver operating characteristic curve analysis was used to evaluate the ability of the RDOS to identify patients with self-reported dyspnea. The average content validity index at the scale level was 0.95. Data from the 128 patients were collected and analyzed. Cohen’s weighted kappa coefficient and the correlation coefficient between the two scales were 0.76 and 0.443 (95% confidence intervals 0.70–0.82 and 0.23–0.62), respectively. For predicting self-reported dyspnea, the area under the receiver operating characteristic curve was 0.81 (95% confidence interval 0.67–0.97). The optimal cutoff used was 1, with a sensitivity and specificity of 0.89 and 0.61, respectively. Our findings indicated that the Japanese version of the RDOS is acceptable for face validity, understandability, criterion validity, and inter-rater reliability in lightly sedated mechanically ventilated patients, indicating its clinical utility.
