CHOSEN Risk Score for COVID-19 Safe Discharge

Description

Calculates the CHOSEN (COVID Home Safely Now) score to predict the likelihood of a safe discharge for patients with COVID-19. The model uses Age, Sex, Respiratory Rate, Oxygen Saturation, and Albumin to estimate the probability of not requiring ICU admission, intubation, or dying (safe discharge).

Usage

chosen_covid_risk_score(age, sex, respiratory_rate, spo2, albumin,
                        albumin_units = "g/dL")

Arguments

age	Numeric. Patient age in years.
sex	String. Patient sex ("Male" or "Female").
respiratory_rate	Numeric. Respiratory rate in breaths per minute.
spo2	Numeric. Oxygen saturation on room air (%).
albumin	Numeric. Serum albumin level.
albumin_units	String. Units for albumin. "g/dL" (default) or "g/L".

Value

A list containing:

Probability_Safe_Discharge	The estimated percentage chance of a safe outcome (no ICU/Intubation/Death).
Risk_Category	Classification (Low/Safe, Intermediate, High/Unsafe).
Recommendation	Clinical guidance regarding discharge vs. admission.

Examples

# Example 1: Safe Candidate
# 40yo Female, RR 16, SpO2 98%, Alb 4.0

# Example 2: High Risk
# 75yo Male, RR 24, SpO2 92%, Alb 2.5
chosen_covid_risk_score(75, "male", 24, 92, 2.5)
