Conclusion:
The Roth score, particularly the counting component, increased in patients who were discharged after AECOPD treatment, indicating its potential utility in aiding hospitalization or discharge decisions in the emergency department setting. The score could serve as a quick, non-invasive tool to assess the severity of AECOPD and guide clinical management.
Materials and Methods:
Conducted prospectively from March 1, 2023, to January 1, 2024, the study included 101 patients with Group E COPD, treated in the emergency department of a tertiary hospital. Patients were categorized based on whether they were hospitalized or discharged. The Roth score, which measures breath-holding time following forced inspiration, was recorded in seconds and rhythmic counts. The study also evaluated changes in arterial blood gas parameters and transcutaneous oxygen saturation before and after AECOPD treatment.
Results:
Among the 101 patients (57 males, 44 females), with an average age of 61.4 years, the Roth score demonstrated strong predictive value post-treatment:
- Roth Score Duration: Area under the curve (AUC) = 0.937, with a sensitivity of 92% and specificity of 75% at a cutoff of 9.5 seconds.
- Roth Score Count: AUC = 0.969, with a sensitivity of 97% and specificity of 70% at a cutoff of 10.5.
