Insights
The pre-endoscopic Rockall Score (pRS) best predicts mortality and readmission in upper gastrointestinal bleeding (UGIB) patients. This score aids in identifying high-risk individuals for better emergency management and discharge planning.
Area of Science:
- Gastroenterology
- Emergency Medicine
- Clinical Risk Stratification
Background:
- Upper gastrointestinal bleeding (UGIB) is a common emergency requiring accurate risk assessment.
- Evaluating pre-endoscopic scoring systems is crucial for timely patient management.
Purpose of the Study:
- To compare the predictive accuracy of the pre-endoscopic Rockall Score (pRS), Glasgow-Blatchford Score (GBS), and AIMS65 for 30-day mortality and hospital readmission in UGIB patients.
- To assess the utility of these scoring systems in Iranian tertiary hospitals.
Main Methods:
- A prospective observational study involving 290 adult UGIB patients.
- Assessment using pRS, GBS, and AIMS65 at admission.
- Statistical analysis including ROC curves and AUC comparisons to evaluate prognostic accuracy.
Main Results:
- The pre-endoscopic Rockall Score (pRS) demonstrated the highest predictive accuracy for both mortality (AUROC=0.815) and readmission (AUROC=0.605).
- High sensitivity and NPV were observed for all scores at low-risk thresholds, with pRS offering the best prognostic balance.
- Shock, tachycardia, syncope, altered mental status, and severe comorbidities were significantly linked to adverse outcomes.
Conclusions:
- The pre-endoscopic Rockall Score (pRS) is highly effective for identifying high-risk UGIB patients and guiding early management.
- pRS's strong sensitivity and NPV support its use in discharge planning and risk stratification in emergency settings.
- Further validation in diverse settings is recommended to optimize UGIB management strategies.
Background:
Upper gastrointestinal bleeding (UGIB) is a frequent emergency requiring prompt risk stratification for effective management. This study evaluates the predictive accuracy of three pre-endoscopic scoring systems-Glasgow-Blatchford Score (GBS), AIMS65, and pre-endoscopic Rockall Score (pRS)-in forecasting 30-day mortality and hospital readmission among UGIB patients in Iranian tertiary hospitals.
Methods:
A prospective observational study was conducted at Al-Zahra and Khorshid Hospitals (Isfahan, Iran) between April 2024 and April 2025. Adult patients presenting with UGIB symptoms were assessed using pRS, GBS, and AIMS65. Data were collected prospectively at the time of admission and during hospitalization using standardized clinical forms and patient records. Statistical analyses-including receiver operating characteristic (ROC) curves, area under the curve (AUC) comparisons, sensitivity, specificity, and predictive values-were performed to determine each system's prognostic utility.
Results:
Among 290 enrolled patients, 30-day mortality occurred in 23.4%, with shock, tachycardia, syncope, altered mental status, and severe comorbidities significantly associated with adverse outcomes (p < 0.001). pRS exhibited the highest predictive accuracy for mortality (AUROC = 0.815) and readmission (AUROC = 0.605), outperforming GBS and AIMS65, though the difference between pRS and AIMS65 was not statistically significant (p = 0.924). At low-risk thresholds (pRS < 1, GBS < 2, AIMS65 < 1), all three systems demonstrated high sensitivity and negative predictive value (NPV), with pRS showing the best balance of prognostic performance.
Conclusion:
The pre-endoscopic Rockall Score proved most effective for identifying high-risk UGIB patients and guiding early management. Its strong sensitivity and negative predictive value support its role in safe discharge planning and risk stratification in emergency settings. Further validation in diverse clinical contexts is recommended to enhance UGIB management strategies.
