Table 1 Table of metritis score definitions and examples of present usage in practice.

From: Veterinary decision making in relation to metritis - a qualitative approach to understand the background for variation and bias in veterinary medical records

Scores Clinical signs - vaginal examination Cases
   Practical scoring Decision making on treatment
0 None or very small amount of clean mucous discharge - no odour L elaborates on the use of score 0: "Well, some should maybe have been 1 or 2. The score 1 I have never used." L scores all cows with a normal puerperal discharge 0.  
1 A very small amount of bloody mucous discharge - no odour   
2 Small amount of bloody mucous/grey discharge - no odour   
3 Large amounts of bloody seromucous/grey-yellow discharge - scabs on tail - no odour J: "I use 2 - which means I will not treat, but I would like to see the cow again for control [...] I could use 3-4. But I just use 2, and the farmer knows what it means". J uses 0 for cows that are immediately characterized as non metritic.  
4 Large amounts of grey/yellow seromucous discharge - no abnormal odour K: "My metritis score 4. It is when there is plenty of discharge, that smells and there is no temperature".
J: "I can not differentiate as sharp as it is suggested by the system, so I only use 5-7-9".
A uses 4 and rectal temperature as a minimum threshold for metritis treatment.
5 Little to medium amounts of purulent discharge - difference in consistency and colour - smell abnormal   L uses the combination of score 4 and a flaccid uterus by rectal examination to initiate treatment with prostaglandin.
6 Medium amounts of discharge - difference in texture and colour - smell abnormal   K, I, E, J & B are explicitly using 5 as a minimum threshold for treatment.
7 Medium to large amounts of discharge - beginning to look red-brownish - stinks I: "I have never given a cow score 9 if she was not very ill. We saw a cow I gave 8 [...]If she had had sunken eyes I had probably given her 9 with the same vaginal findings" D, C, L, & H using a variable threshold for treatment and makes individual decision on individual cows based on multiple clinical criteria (incl. metritis score).
8 Large amounts of greyish discharge - stinks K's scoring is influenced by rectal temperature: the higher temperature, the higher metritis score. H attempts to exclude score 8-9 from the scale: "If they have a cow there is as sick as 8-9 they should call in advance. "
9 Large amounts of brown-yellow/brown discharge- typically a retained placenta - "smells like h...!"   
  1. The table explains the metritis scores with definitions. Cases from the interviews are given to demonstrate how the scores are used in a practice context, and how they are used during decision making for determining treatment threshold for metritis. Capital letters refer to specific veterinarians.
