Morisky Scale for Medication Adherence
This is a draft cheat sheet. It is a work in progress and is not finished yet.
The Morisky scale is a validated scale designed to estimate the risk of medication non-adherence. It has been cited in over 70 articles since its publication in 1986. It’s used for many different diseases such as hypertension, hyperlipidemia, asthma, and HIV. Scores are based on patient responses to four, Yes or No questions.

Scoring the Morisky Scale
Yes=0 and No=1
• Zero is the lowest level of medication adherence
• 4 is the highest level of medication adherence
• Patients scoring 0 or 1 would benefit most from pharmacist intervention
• Goal: screen for those in which your pharmacist time should be spent on enhancing adherence
