Medication Appropriateness Index (MAI)
|
Background - using this tool
|
This tool requires the user to answer 10 questions regarding a particular
medication in order to determine its appropriateness for a patient. The
score is automatically calculated after submitting the responses.
The indication and effectiveness of a particular drug are given the most weight.
All 'yes' responses have a score of zero, while 'no' responses have values
ranging from 1 to 3 depending on its importance in assessing the appropriateness
of a particular drug. The maximum score is 18 which translates into
maximum inappropriateness. If a patient is on multiple drugs, this test
can be repeated for each drug in order to determine a total MAI score (simply
add the results for each drug reviewed). 1,2,3
