Abstract

Introduction: The disposition decision is a great challenge for clinicians in managing patients with Chronic Obstructive Pulmonary Disease (COPD) exacerbation. This study aimed to evaluate the accuracy of Ottawa COPD Risk Scale (OCRS) in predicting the short-term adverse events in the mentioned patients. Methods: This prospective diagnostic accuracy study was conducted on COPD exacerbation cases who were referred to the emergency department (ED). Patients were followed up for 30 consecutive days for adverse events including the need for intubation, non-invasive ventilation, myocardial infarction, readmission, and death from any cause, and finally the accuracy of OCRS in predicting the outcome was evaluated. Results: 362 patients with the mean age of 65. 55 ±,10. 65 (6-95) years were evaluated (58. 0% male). Among the patients, 164 (45. 3%) cases were discharged from ED, and 198 (54. 7%) were admitted to the hospital. 136 (37. 6%) cases experienced at least one of the studied short-termadverse events. The mean OCSD score of this series was 1. 96 ±,2. 39 (0 –,10). The area under the curve of OCRS in predicting the outcome of COPD patients was 0. 814 (95%CI: 0. 766 –,0. 862). The best cut-off point of the scale in predicting the outcome was 1. 5. The Sensitivity and Specificity of the scale were 75. 75% (95%CI: 69. 6% –,81. 42%) and 89. 63% (95%CI: 83. 67% –,93. 66%), respectively. By employing this threshold, 48 (13. 25%) cases would have unnecessary hospitalization, and 17 (0. 04%) would be discharged incorrectly. Conclusion: The OCRS has acceptable level of prediction accuracy in predicting the short-term adverse event of COPD patients. The use of this scoring in the routine practice of ED clinicians can lead to a reduction in unnecessary admissions and unsafe discharge for these patients.
