total score =
= SUM(points for all of the parameter)
Interpretation:
• minimum score: 0
• maximum score with complementary drug: 30
• The higher the score the more appropriate the drug therapy.
• If no complementary drug is given, or if more than 1 is given, then the point assignment is adjusted.
The above score is combined with a demerit score for problems in the prescription.
