CREST score

Q: How many features are there in CREST score?

 Answer: Five 

 There are two scores available to predict outcomes in out of hospital CPR. One is the NULL PLEASE score and the other is the CREST score. NULL PLEASE has 10 features in it which was presented yesterday at this site. To simplify it further CREST score has only five features. Moreover, CREST score is solely concentrated towards cardiac features. This is validated via a study from the registry of the International Cardiac Arrest Registry (INTCAR).

•  Coronary artery disease history
• Rhythm found to be unshockable
• Ejection fraction less than 30%
• Shock at presentation 
• Time (prior to ROSC) >25 minutes 

 The risk of circulatory death increased with every additional point, from 10 percent mortality with CREST = 0 up to 50 percent mortality with CREST = 5.
