HOPE Score for Hypothermia Outcome Prediction

Description

Calculates the HOPE score to estimate the probability of survival in patients with hypothermic cardiac arrest undergoing Extracorporeal Life Support (ECLS) rewarming. The score uses age, sex, hypothermia mechanism (asphyxia vs non-asphyxia), CPR duration, serum potassium, and core temperature.

Usage

hope_score_hypothermia(age, sex, mechanism_hypothermia, cpr_duration_min,
                       potassium_mmol_l, temperature_c)

Arguments

age	Numeric. Patient age in years.
sex	String. Patient sex ("Male" or "Female").
mechanism_hypothermia	String. Mechanism of hypothermia. "asphyxia" (e.g., submersion, avalanche) or "non-asphyxia" (e.g., exposure). Non-asphyxia is a positive predictor.
cpr_duration_min	Numeric. Duration of cardiopulmonary resuscitation in minutes.
potassium_mmol_l	Numeric. Serum potassium level in mmol/L.
temperature_c	Numeric. Core body temperature in degrees Celsius.

Value

A list containing:

HOPE_Score_Probability	The estimated percentage probability of survival to hospital discharge.
Recommendation	Guidance on ECLS utility based on the calculated probability.

Examples

# Example 1: Good Prognosis
# 30yo Male, Non-asphyxia (Exposure), CPR 60 min, K 4.0, Temp 28C
hope_score_hypothermia(30, "male", "non-asphyxia", 60, 4.0, 28)

# Example 2: Poor Prognosis
# 60yo Female, Asphyxia (Drowning), CPR 90 min, K 8.0, Temp 30C
hope_score_hypothermia(60, "female", "asphyxia", 90, 8.0, 30)
