Avoiding the futility of resuscitation

Area of Science:

• Emergency Medicine
• Critical Care Medicine
• Cardiology

Background:

• Cardiopulmonary resuscitation (CPR) is a critical intervention for patients experiencing cardiac arrest.
• Determining the futility of CPR is essential for appropriate patient care and resource allocation.

Purpose of the Study:

• To identify patient characteristics and circumstances associated with poor outcomes following CPR.
• To establish criteria for withholding or discontinuing resuscitation efforts.

Main Methods:

• A multi-disciplinary, prospective study of 200 consecutive patients with cardiopulmonary arrest.
• Data collected included age, sex, arrest location, CPR duration, recovery, hospital discharge, and 6-week survival.
• Factors analyzed included sepsis and co-morbid conditions.

Main Results:

• Overall, 12.0% of patients were discharged from the hospital, and 8.5% survived for 6 weeks.
• In-hospital arrests had a significantly higher 6-week survival rate (13.7%) compared to field/emergency room arrests (1.2%).
• Factors negatively impacting prognosis included arrest outside the hospital, sepsis, three or more co-morbid conditions, and asystole.

Conclusions:

• CPR survival rates are generally low, with particularly poor outcomes for out-of-hospital arrests.
• Resuscitation efforts may be futile in a majority of patients with specific negative prognostic indicators.
• Recommendations include terminating CPR for pulseless patients after communication with ER physicians and advising families on futility.
