Instructions:


Best use case: Score after initial encounter (HPI, PE, ECG) prior to further results.


A score of 3+ is considered a rule in for ACS anything less necessitates modifiers, which add additional points, for rule in.


Note: A score of 2 places highest priority of rapidly evaluating for potential modifiers


This tool is dynamic. Significant changes in ECG or Clinical Picture necessitate fresh scoring from step one.

Step 1

Clinical Picture

(DO YOU BUY IT?)


Your pretest probability: Is it the top differential, on your working differential, or not?

Yes,

MODIFIERS

(+1 each*)

  1. Troponin

Not simply a positive result.


  • Must support ACS or raise the probability of it on your differential.


*Bonus point w/ repeat lab

(+1 each for +2 total)


Not simply a rise in value.


  • Result must meaningfully increase the probability on your differential including if repeated and second result.

  1. Bedside Echo

RWMA, HFrEF, etc.


  1. Values

Shared decision making.


  • Patient prefers aggressive treatment strategy prior to further testing


  • Risk/Benefit favors aggressive treatment (baseline poor EF, rural ED, low risk for bleeding, etc.)
