Clinical Performance of Prediction Rules and Nasogastric Lavage for the Evaluation of Upper Gastrointestinal Bleeding: A Retrospective Observational Study

Scoring algorithms.

(a) Tamarro score

Clinical parameter	Score
	1	2	3
General conditions	Poor	Intermediate	Good
Pulse (beats/min)	>110	90–110	<90
Systolic blood pressure (mmHg)	<90	90–110	>110
Hemoglobin level (g/dL)	≤8	9-10	>10

T-score is sum of the corresponding values for each clinical parameters.
≤6 corresponds to T1 (high-risk), 7–9 to T2 (intermediate-risk), and ≥10 to T3 (low-risk).

(b) Adamopoulos score

---

Total points = [6 (if fresh blood in NGT) + 4 (if hemodynamically unstable) + 4 (if hemoglobin < 8 g/dL) + 3 (if WBC > 12,000/µL)].

Score <7 = low risk, score ≥11 = high risk.

(c) Clinical Rockall score (before endoscopy)

Clinical parameter	Score
	0	1	2	3
Age (years)	<60	60–79	≥80
Shock	“No shock” SBP ≥ 100 mmHg, pulse < 100/min	“Tachycardia” SBP ≥ 100 mmHg, pulse ≥ 100/min	“Hypotension” SBP < 100 mmHg
Comorbidity	No major comorbidities		CHF, ischemic heart disease, any major comorbidity	Renal failure, liver failure, disseminated malignancy
