rockall_score_complete: Rockall Score for Upper GI Bleeding (Complete)

Description

Calculates the complete Rockall Score to predict the risk of mortality and rebleeding in patients with upper gastrointestinal bleeding. This version requires endoscopic findings (diagnosis and stigmata of recent hemorrhage).

Usage

rockall_score_complete(age, systolic_bp, heart_rate, comorbidity_category,
                       diagnosis_category, major_stigmata_present)

Value

A list containing:

Rockall_Score

The calculated score (Range 0-11).

Mortality_Risk

Estimated mortality risk percentage.

Rebleed_Risk

Estimated rebleeding risk percentage.

Arguments

age

Numeric. Patient age in years.

systolic_bp

Numeric. Systolic blood pressure in mmHg.

heart_rate

Numeric. Heart rate in beats per minute.

comorbidity_category

String. Major comorbidities. "none": No major comorbidity (0 pts). "cardiac_other": Heart failure, ischemic heart disease, or other major morbidity (2 pts). "renal_liver_metastatic": Renal failure, liver failure, or metastatic cancer (3 pts).

diagnosis_category

String. Diagnosis determined by endoscopy. "mallory_weiss_none": Mallory-Weiss tear or no lesion identified (0 pts). "all_other": All other diagnoses (e.g., ulcers, erosions, esophagitis) (1 pt). "malignancy": Malignancy of the upper GI tract (2 pts).

major_stigmata_present

Numeric (0 or 1). Presence of major stigmata of recent hemorrhage (blood in upper GI tract, adherent clot, visible or spurting vessel). (1 = Yes, +2 pts). Note: Clean base or dark spot only is 0 pts.
