BACKGROUND
The Respiratory Distress Observation Scale (RDOS) is a means for assessing respiratory distress when a patient is unable to give a dyspnea self-report. Cut-point determination was needed to guide clinical application.
METHOD
A Receiver Operating Characteristic (ROC) curve analysis was conducted in a prospective, observation study with inpatients ranked by nurse practitioners (NP) into levels of respiratory distress. A research assistant simultaneously measured RDOS blinded to NP ranking.
RESULTS
Participants were 84 adults: mean age of 72.6 (SD = 15.2) years, 53.6% male, 77.4% African-American. NP ranking was distributed: none (30%), mild (26%), moderate (31%), and severe (13%) distress. RDOS scores ranged 0-13 (M = 4.8, SD = 3). NP ranking was significantly correlated with RDOS (rho = .91, p < .01). ROC curve analyses yielded cut-points: none = 0-2, any = 3, mild-moderate = 4-6, and severe ≥7 (p < .01).
CONCLUSIONS
Intensity cut-point enhances the clinical utility of the RDOS.
背景
呼吸窘迫观察量表（RDOS）是一种在患者无法进行呼吸困难自我报告时评估呼吸窘迫的方法。需要确定切点以指导临床应用。
方法
在一项前瞻性观察研究中进行了受试者工作特征（ROC）曲线分析，由执业护士（NP）将住院患者按呼吸窘迫程度进行分级。一名研究助理在对NP分级不知情的情况下同时测量RDOS。
结果
参与者为84名成年人：平均年龄72.6（标准差=15.2）岁，男性占53.6%，非裔美国人占77.4%。NP分级分布如下：无（30%）、轻度（26%）、中度（31%）和重度（13%）窘迫。RDOS评分范围为0 - 13（中位数=4.8，标准差=3）。NP分级与RDOS显著相关（rho = 0.91，p < 0.01）。ROC曲线分析得出切点：无=0 - 2，有=3，轻度至中度=4 - 6，重度≥7（p < 0.01）。
结论
强度切点提高了RDOS的临床实用性。
