Description

The Mainz Emergency Evaluation Score (MEES) is a dynamic scoring system for prehospital emergency medical services. It is not intended to predict outcome but can be used to evaluate the efficacy and quality of the prehospital interventions.


NOTES: This score was recommended for inclusion by Dr Martin Dehler. A modification of the MEES to include capnometry can be used to evaluate patients who have had cardiopulmonary resuscitation in a prehospital setting.

 

Parameters:

(1) Glasgow coma scale

(2) heart rate

(3) respiratory rate

(4) cardiac rhythm

(5) pain

(6) blood pressure

(7) oxygen saturation

• I am not sure what ABSARRH means. It appears to mean "absolute arrhythmia".

• I am not sure of the translation for entfallt. 

 

Mainz emergency evaluation score =

= SUM(points for the 7 parameters)

 

Interpretation:

• minimum score: 7 (Hennes et al 1993 state that the minimum score is 8; the lowest score for pain is 2, since pain is not life-threatening).

• maximum score: 28

• The higher the score, the better the patient's condition.

• If a life-threatening score is present (1 point) for any parameter, then an "*" is added to the sum to indicate that the condition is life-threatening.

• Scoring is performed twice - first at the scene of the accident and again at the emergency department.

• If the second score is >= 2 points greater than the initial score, then the patient's condition is considered improved. If the second is more than 2 points less than the initial score, then the patient is considered to have deteriorated. Else (difference of -1 to +1) it is considered unchanged.
