GO-FAR Score for In-Hospital CPR Outcomes
Predicts survival with favorable neurological outcome after in-hospital cardiac arrest treated with CPR
Calculator
Why use it
Survival rates after in-hospital CPR are far lower than commonly perceived by patients and families (median survival ~20%). GO-FAR provides an individualized, evidence-based estimate of CPR survival probability, enabling more informed advance care planning and goals-of-care discussions. It is particularly useful for identifying patients for whom CPR has a very low probability of benefit, facilitating discussions about DNAR/DNR orders, palliative care, and alternative goals of care.
About
The GO-FAR (Good Outcome Following Attempted Resuscitation) Score was developed by Ebell and colleagues to predict the likelihood of survival to discharge with favorable neurological outcome following in-hospital cardiac arrest (IHCA) treated with CPR. Published in JAMA Internal Medicine in 2013, GO-FAR was derived from the Get With The Guidelines-Resuscitation (GWTG-R) registry including over 51,000 patients. The tool uses 13 pre-arrest clinical variables that can be assessed at any time before the cardiac arrest event. GO-FAR scores range from -15 to +28, with higher scores predicting worse outcomes. Four risk categories are defined, with survival rates ranging from approximately 27% (Very Good prognosis group) to less than 1% (Very Poor prognosis group). GO-FAR is used primarily as a communication and shared decision-making tool in goals-of-care discussions about CPR preferences.
When to use
- Goals-of-care conversations about CPR with patients or family members on hospital admission
- Identifying patients for whom the probability of CPR success is very low
- Informing advance directive discussions in seriously ill inpatients
- Multidisciplinary team discussions about appropriate resuscitation status
- ICU or oncology ward care planning discussions
- Not to be used to unilaterally withhold CPR — only as a decision-support and communication tool
Formula
Pearls & pitfalls
- GO-FAR predicts survival WITH GOOD NEUROLOGICAL OUTCOME — not just return of spontaneous circulation (ROSC). Overall ROSC rates are higher but mean little without functional recovery.
- The score was derived in the Get With The Guidelines-Resuscitation database — a US registry; generalizability to other settings (non-US, community hospitals) may vary.
- GO-FAR is a PRE-ARREST tool — it is used BEFORE cardiac arrest occurs to guide advance care planning, not to triage resuscitation after arrest begins.
- Even patients in the "Very Good" category (Score ≤-5) have only a ~27% survival rate — all CPR discussions should convey realistic expectations.
- GO-FAR should NEVER be used to unilaterally withhold resuscitation — it is a communication and shared decision-making tool, not a mandate.
- Age alone is a strong predictor — patients ≥70 years score higher (worse prognosis) than younger patients with similar clinical profiles.
- Non-shockable rhythms (PEA/asystole) have substantially worse outcomes than ventricular fibrillation/pulseless VT — rhythm at arrest is not in GO-FAR but is critical.
- Metastatic cancer adds the highest single point weight in GO-FAR (+11), reflecting the dramatically poor prognosis of IHCA in this population.
Next steps
Very Good (Score ≤-5): ~27% survival with favorable neurological outcome. Discuss realistic expectations — CPR may be beneficial. Good (Score -4 to 0): ~12% survival. Review CPR preferences with balanced discussion of risks and benefits. Average (Score 1–5): ~6% survival. Emphasize low survival probability. Explore patient values and goals. Initiate palliative care if not already involved. Poor (Score 6–13): ~3% survival. High probability of CPR futility. Comprehensive goals-of-care discussion. Consider DNAR. Very Poor (Score ≥14): <1% survival. CPR very unlikely to result in meaningful recovery. Palliative care consultation strongly recommended. DNAR discussion essential.
