rescue_ihca_score: 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)

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.

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.

Examples

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

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