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)

Arguments

age	Numeric. Patient age in years. <70: 0 pts. 70-74: +2 pts. 75-79: +5 pts. 80-84: +6 pts. >=85: +11 pts.
neurologically_intact_admission	Numeric (0 or 1). Neurologically intact (CPC 1) or minimal deficits at admission. (1 = Yes, -15 pts).
major_trauma	Numeric (0 or 1). Major trauma during current admission. (1 = Yes, +10 pts).
acute_stroke	Numeric (0 or 1). Acute ischemic or hemorrhagic stroke during current admission. (1 = Yes, +8 pts).
metastatic_hematologic_cancer	Numeric (0 or 1). Metastatic or hematologic malignancy. (1 = Yes, +7 pts).
septicemia	Numeric (0 or 1). Septicemia. (1 = Yes, +7 pts).
medical_noncardiac_diagnosis	Numeric (0 or 1). Medical non-cardiac diagnosis on admission. (1 = Yes, +7 pts).
hepatic_insufficiency	Numeric (0 or 1). Hepatic insufficiency. (1 = Yes, +6 pts).
skilled_nursing_facility	Numeric (0 or 1). Admission from a skilled nursing facility (SNF). (1 = Yes, +6 pts).
hypotension_hypoperfusion	Numeric (0 or 1). Hypotension or hypoperfusion within 4 hours prior to arrest. (1 = Yes, +5 pts).
renal_insufficiency_dialysis	Numeric (0 or 1). Renal insufficiency or dialysis. (1 = Yes, +4 pts).
respiratory_insufficiency	Numeric (0 or 1). Respiratory insufficiency. (1 = Yes, +4 pts).
pneumonia	Numeric (0 or 1). Pneumonia. (1 = Yes, +1 pt).

Value

A list containing:

GO_FAR_Score	The calculated score.
Probability_Neurologically_Intact_Survival	Estimated probability of survival with good neurological outcome.
Risk_Group	Classification (Very Low, Low, Average, Above Average).

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)
# Score = 24
