RESCUE-IHCA Score for ECPR Survival

Description

Calculates the RESCUE-IHCA score to predict the probability of survival to hospital discharge in patients with in-hospital cardiac arrest (IHCA) who are being considered for Extracorporeal Cardiopulmonary Resuscitation (ECPR). The score stratifies patients based on age, renal history, time of arrest, initial rhythm, and etiology.

Usage

rescue_ihca_score(age, history_renal_insufficiency, time_of_arrest_day,
                  initial_rhythm_shockable, etiology_cardiac)

Arguments

age	Numeric. Patient age in years. <60: +6 pts. 60-74: +2 pts. >=75: 0 pts.
history_renal_insufficiency	Numeric (0 or 1). History of renal insufficiency (e.g., creatinine > 1.5 mg/dL or CKD). (1 = Yes, -2 pts).
time_of_arrest_day	Numeric (0 or 1). Did the arrest occur during daytime hours (08:00 to 16:59)? (1 = Yes, +2 pts).
initial_rhythm_shockable	Numeric (0 or 1). Was the initial rhythm shockable (VF or pVT)? (1 = Yes, +2 pts).
etiology_cardiac	Numeric (0 or 1). Is the etiology of the arrest primary cardiac (Medical-Cardiac or Surgical-Cardiac)? (1 = Yes, +4 pts). Note: Non-cardiac etiologies score 0.

Value

A list containing:

RESCUE_IHCA_Score	The calculated score (Range -2 to 16).
Est_Survival_to_Discharge	Estimated probability of survival to hospital discharge based on the derivation cohort.

Examples

# Example 1: Good Candidate
# 50yo (+6), No Renal, Day Arrest (+2), VF (+2), Cardiac Cause (+4)
# Score = 14
rescue_ihca_score(50, 0, 1, 1, 1)

# Example 2: Poor Candidate
# 78yo (0), Renal Hx (-2), Night Arrest (0), PEA (0), Non-Cardiac (0)
# Score = -2
rescue_ihca_score(78, 1, 0, 0, 0)
