| Abstract | BACKGROUND Standard measures of dyspnea rely on self-report. Cognitive impairment and nearness to death may interfere with symptom distress reporting leading to underrecognition and overtreatment or undertreatment. Previous psychometric testing of the Respiratory Distress Observation Scale (RDOS) demonstrated internal consistency and convergent validity with dyspnea self-report and discriminant validity with pain and no dyspnea. Additional testing was needed with patients unable to self-report. The aim of this study was to establish further the reliability and construct validity of a revised RDOS. METHODS An observational design was used with 89 consecutive patients referred for inpatient palliative care consultation and at risk for dyspnea who had one or more of lung cancer, chronic obstructive pulmonary disease (COPD), heart failure, or pneumonia. Patients were observed and the RDOS scored once each day for up to three days after the initial consultation. Other measures included: dyspnea self-report, neurologic diagnoses, opioid or benzodiazepine use, peripheral oxygen saturation, end-tidal carbon dioxide level, consciousness, cognitive state, nearness to death, and patient demographics. RESULTS Perfect interrater reliability across data collectors was achieved. No differences in RDOS scoring were found by patient demographics. RDOS was associated with use of oxygen (p < 0.01), oxygen saturation (p < 0.01) and nearness to death (p < 0.01). A significant decrease in RDOS was found over time corresponding with treatment (p < 0.01). The reliability of this 8-item scale using Cronbach alpha is 0.64. CONCLUSIONS Declining consciousness and/or cognition are expected when patients are near death. The RDOS performed well when tested with terminally ill patients who were at risk for respiratory distress, most of whom could not self-report dyspnea. The tool is sensitive to detect changes over time and measure response to treatment. The RDOS is simple to use; scoring takes less than 5 minutes. The RDOS has clinical and research utility to measure and trend respiratory distress and response to treatment. |
