go_far_cardiac_arrest_score: GO-FAR Score for In-Hospital Cardiac Arrest Outcome

Description

Calculates the Good Outcome Following Attempted Resuscitation (GO-FAR) score to predict the likelihood of survival to discharge with good neurological outcome (CPC 1) after an in-hospital cardiac arrest (IHCA). The score uses pre-arrest variables available at admission or shortly before the event to stratify patients into risk categories.

Usage

go_far_cardiac_arrest_score(age, neurologically_intact_admission, major_trauma,
                            acute_stroke, metastatic_hematologic_cancer, septicemia,
                            medical_noncardiac_diagnosis, hepatic_insufficiency,
                            skilled_nursing_facility, hypotension_hypoperfusion,
                            renal_insufficiency_dialysis, respiratory_insufficiency,
                            pneumonia)

Examples

# Example 1: Low Probability of Survival
# 85yo (+11), SNF (+6), Renal (+4), Neuro Intact (-15)
# Score = 11 + 6 + 4 - 15 = 6 (Average Probability? No wait, +6 is Average range -5 to 13)
# Let's check risk group: Score 6 -> Average Probability (3-15%)

# Example 2: Very Low Probability
# 75yo (+5), Metastatic Cancer (+7), Sepsis (+7), Hypotension (+5), Not Neuro Intact (0)
