rapid_pleural_infection_score: RAPID Score for Pleural Infection

Description

Calculates the RAPID Score to predict 3-month mortality in patients with pleural infection. The acronym RAPID stands for Renal (BUN), Age, Purulence, Infection Source, and Diet (Albumin).

Usage

rapid_pleural_infection_score(bun, age, purulent_fluid, hospital_acquired,
                              albumin, bun_units = "mg/dL", albumin_units = "g/dL")

Value

A list containing:

RAPID_Score

The calculated total score (Range 0-7).

Risk_Category

Classification (Low 0-2, Medium 3-4, High 5-7).

Est_3_Month_Mortality

Estimated 3-month mortality percentage.

Arguments

bun

Numeric. Blood Urea Nitrogen level. <14 mg/dL: 0 pts. 14-23 mg/dL: 1 pt. >23 mg/dL: 2 pts.

age

Numeric. Patient age in years. <50: 0 pts. 50-70: 1 pt. >70: 2 pts.

purulent_fluid

Numeric (0 or 1). Is the pleural fluid purulent? (1 = Yes, 0 = No). Note: Non-purulent fluid adds 1 point.

hospital_acquired

Numeric (0 or 1). Is the infection hospital-acquired? (1 = Yes, +1 pt).

albumin

Numeric. Serum Albumin level. (<2.7 g/dL adds 1 point).

bun_units

String. Units for BUN. "mg/dL" (default) or "mmol/L".

albumin_units

String. Units for Albumin. "g/dL" (default) or "g/L".

Examples

# Example 1: Low Risk
# BUN 10, Age 40, Purulent(Yes), Community(0), Alb 3.5
# Score = 0 + 0 + 0 + 0 + 0 = 0
rapid_pleural_infection_score(10, 40, 1, 0, 3.5)

# Example 2: High Risk
# BUN 30 (+2), Age 75 (+2), Non-purulent (+1), Hospital (+1), Alb 2.0 (+1)
# Score = 7
