Mentation is one of the 4Ms of an Age-Friendly healthcare system.
In 2017, the Institute for Healthcare Improvement (IHI), the John A Hartford Foundation (JAHF), the American Hospital Association (AHA), and the Catholic Health Association (CHA) of the United States addressed the development of age-friendly health systems using a clinical framework to improve the complex care of older adults.
These organizations defined and operationalized age-friendly care following the guidelines of beneficence, evidence-based medicine, and patient/family aligned goals and concerns. The 4M Framework was the result: What Matters Most, Mentation, Mobility, and Medication. A 5th M is sometimes incorporated to include Multi-Morbidity, which calls attention to the multiple, often inter-related, health problems that many older adults face.
