概要	The Medication Regimen Complexity Index (MRCI) is a clinician-administered quantitative measure that objectively assesses the complexity of a patient's medication regimen based on the number of medications, frequency of dosing, and form of administration. Developed by Morgado, Rolo, and Castelo-Branco in 2012, the MRCI quantifies an important adherence barrier—the complexity of taking multiple medications with different schedules and administration routes. The MRCI is unique among adherence tools in that it measures an objective regimen characteristic (not patient behavior or belief), making it useful for deprescribing decisions, medication reconciliation, and identifying high-risk patients for non-adherence due to complexity.	The Medication Understanding and Use Self-Efficacy Scale (MUSE-S) is a brief, patient-centered self-report measure assessing both knowledge and confidence regarding medication use. Developed by Kripalani and colleagues at Emory University in 2009, the MUSE-S evaluates whether patients understand their medications (what they are for, how to take them, important side effects) and feel confident managing them in daily life. This dual focus on knowledge and self-efficacy makes the MUSE-S particularly valuable for identifying education gaps, assessing health literacy barriers to medication adherence, and evaluating outcomes of medication counseling or education interventions.
