CURB-65 and PLR Scores for Predicting 30-Day Mortality in Severe Pneumonia

A retrospective study of 214 adult patients with severe community-acquired pneumonia (SCAP) in an emergency department setting. The data was used to evaluate the predictive value of combining the CURB-65 clinical severity score with the platelet-to-lymphocyte ratio (PLR) for 30-day all-cause mortality. The dataset was authored by Chengtian Lv and last updated in June 2026.

Use Cases

• Developing mortality risk prediction models based on clinical scores and blood count ratios.
• Comparing the performance of combined biomarkers against established clinical scores like CURB-65.
• Conducting survival analysis for emergency department patients with severe pneumonia.
• Training classifiers for early risk stratification in clinical settings.

Strengths

• Includes data from 214 adult patients, providing a specific cohort size.
• Reports a 30-day mortality rate of 25.7%, offering a clear outcome metric.
• Compares model performance with specific AUC values (0.702 for CURB-65 alone vs. 0.772 for CURB-65+PLR).
• Identifies CURB-65 as an independent predictor with a specific odds ratio (OR 2.80, 95% CI 1.87–4.18).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is very small at 38.0 KB, indicating limited scope.
• Data may reflect temporal and geographic bias inherent to a single retrospective study.
