Yale observation scales score =

= SUM(points for the 6 observation items)

 

Interpretation:

• minimum score: 6

• maximum score: 30

• If the score is > 10, then the child is termed ill-appearing and the chance of serious illness is 40%.

• If the score is <= 10, then the child is termed well-appearing and the chance of serious illness is 2-3%.
