aims65_upper_gi_bleed: AIMS65 Score for Upper GI Bleeding Mortality

Description

Calculates the AIMS65 score to predict in-hospital mortality in patients with acute upper gastrointestinal bleeding (UGIB). The acronym stands for Albumin, INR, Mental status, Systolic blood pressure, and age 65.

Usage

aims65_upper_gi_bleed(albumin_g_dl, inr, altered_mental_status, sbp_mmhg, age_years)

Value

A list containing:

Total_Score

The calculated AIMS65 score (Range 0-5).

In_Hospital_Mortality_Risk

Estimated mortality percentage based on the validation study.

Risk_Stratification

General classification (High Risk if Score >= 2).

Arguments

albumin_g_dl

Numeric. Serum albumin level in g/dL. (< 3.0 g/dL adds +1 point).

inr

Numeric. International Normalized Ratio. (> 1.5 adds +1 point).

altered_mental_status

Numeric (0 or 1). Presence of altered mental status (GCS < 14 or disorientation). (1 = Yes, +1 point).

sbp_mmhg

Numeric. Systolic blood pressure in mmHg. (<= 90 mmHg adds +1 point).

age_years

Numeric. Patient age in years. (>= 65 years adds +1 point).

# Example 1: High Risk
# Albumin 2.5 (+1), INR 2.0 (+1), Alert (0), SBP 85 (+1), Age 70 (+1)
# Score = 4
