The 4M’s of At-Home Senior Care

Health systems across the country are adopting more age-friendly care practices and principles. In 2020, according to the Centers for Disease Control (CDC), about 17% of the entire U.S. population was 65 or older. As more people age, improving care for older adults is integral to life quality and the care of this population of patients. However, an important setting has historically been less visible in this conversation: the home.

Seniors often spend most of their time at home, and non-medical in-home care providers spend more time with older adults than almost any other part of the care continuum. They observe daily routines, functional changes, successes and setbacks that rarely appear in medical charts.

We wanted to see how understanding and using the 4Ms framework and applying it to in-home care can improve outcomes for older adults. So, we tested it.

A Brief Overview of the 4Ms Framework

The 4Ms framework provides a simple but powerful structure for age-friendly care. Developed in 2016 by the Institute for Healthcare Improvement (IHI) and the John A. Hartford Foundation, the 4Ms framework is built around, of course, four components: what matters, medication, mentation and mobility.

While these are all separate areas of care, they are not intended to be used as separate programs, but rather as an integrated care model to guide all care interactions for older adults. Let’s define each of the 4Ms:

• What Matters: Before care can start, it’s important to understand what an older adult’s goals, values and preferences are so care providers can find solutions to meet them. For example, if an older adult has a goal of being able to walk more independently, it might be helpful for a caregiver to work with them on exercises to improve gait and balance prescribed by a physical therapist. By listening to and understanding what matters for each individual, providers can ensure that care aligns appropriately.
• Medications: Research published in the journal JAMA Internal Medicine reports that 40% of older adults take five or more prescriptions, and TIME reports that almost 20% of American seniors take 10 or more. This pillar of the 4Ms framework aims to ensure that medications do not interfere with the other Ms and that they are used safely and appropriately. It is an integral part of any care strategy. To go back to the first example: For a senior with a goal of walking more independently, certain medications may help or hinder that goal.
• Mentation: Assessing the mentation of a client or patient is an important part of care evaluation, especially with older populations. Mentation in this sense specifically addresses cognition, mood and emotional well-being, including risks such as depression and delirium. For example, an older adult in a late stage of Alzheimer’s will require a different kind of care than a senior with early signs of dementia—especially at home.
• Mobility: Returning to the senior with a goal of walking, mobility is a core component of independence and quality of life. This pillar of the 4Ms emphasizes maintaining safe movement and function to support independence and prevent decline.

When applied consistently and together, the 4Ms help care teams move beyond task completion and toward truly person-centered care.

Extending Age-Friendly Care Into the Home

While the 4M system originated in clinical settings, many of its most meaningful applications occur in everyday life. Whether it’s struggles with hydration, meal preparation, safe transportation or even managing daily routines, these challenges impact health outcomes but are rarely addressed in short clinical encounters.

Non-medical in-home care providers are uniquely positioned to use the 4M framework to support these care challenges slipping through the cracks. In-home caregivers can assist with activities of daily living (ADLs), reinforce care plans, observe changes in condition and more. When trained in age-friendly principles, caregivers can intentionally connect daily activities to the 4Ms—supporting mobility during routine movement, recognizing changes in mentation and aligning care tasks with what matters to the individual.

Remember the senior with the goal of walking more independently? A caregiver can help them meet their goal by helping them with their prescribed physical therapy exercises, going for walks with them, keeping up with medication reminders and ensuring they have the proper dress for an activity. That’s a real-world application of the 4Ms framework at home.

Proven Results

In a recent evaluation published in the Journal of Gerontological Nursing, Senior Helpers and CHAP examined outcomes among more than 11,000 older adults receiving non-medical in-home care. They wanted to see exactly how applying the 4Ms framework to homecare influenced older adults within Senior Helpers’ care.

Information was drawn from structured assessments conducted throughout 2024, along with client and family narratives collected with informed consent. The results, which you can see in the chart above, showed improvement across several practical domains closely tied to independence and quality of life. Among those receiving ongoing in-home support, they observed:

• 71% improvement in getting groceries and supplies
• 67% improvement in completing ADLs, hydration and nutrition
• 54% improvement in mobility and trips outside the home
• 40% improvement in medical condition management

While these percentages reflect functional change rather than clinical endpoints, they point to a meaningful pattern: Consistent support with everyday activities can help stabilize or improve factors closely linked to health, safety and autonomy. These observed improvements align naturally with the 4Ms framework—mobility gains, improvements in factors that affect mood, increased medication management and greater independence.

Looking Ahead

It is important to note that these findings are preliminary and descriptive. They do not establish causation, and further study is needed to better understand long-term impacts, particularly related to healthcare utilization. However, the data suggests that non-medical homecare can meaningfully extend age-friendly principles into the home—where older adults live their daily lives.

As age-friendly care continues to evolve, fully supporting older adults will require recognizing all contributors to their well-being. When the 4Ms are brought home, care becomes more continuous, more personal and more aligned with what matters most to the people we serve.
