Safe Medication Practices in Senior Care: What You Need to Know About 42 CFR 483.45

Share this post

As a senior care provider, your top priority is the safety, dignity, and well-being of your residents.

One of the most critical aspects of achieving this goal is ensuring safe and effective medication use.

That's why 42 CFR 483.45, a federal regulation enforced by the Centers for Medicare & Medicaid Services (CMS), deserves your full attention.

This regulation mandates Medication Regimen Reviews (MRRs) in long-term care facilities, reviews that go beyond compliance and serve as a frontline defense against adverse drug events, hospitalizations, and declining quality of life.

What Does 42 CFR 483.45 Require?

Under this regulation, a licensed pharmacist must review each resident’s medication regimen at least once a month. The goal is to identify:

• Unnecessary medications

• Adverse drug reactions

• Drug-drug interactions

• Particular concerns for residents on antipsychotics or with complex medication needs

These findings must be communicated promptly to the attending physician, medical director, and director of nursing.

Just as importantly, the facility must either implement the pharmacist’s recommendations or provide documented, clinically justified reasons for not doing so.

Why It Matters to Your Facility

Medication errors and overuse in senior care aren’t just regulatory red flags, they’re serious safety risks. Poor medication management can lead to:

• Emergency hospital visits

• Increased morbidity

• Accelerated cognitive or functional decline

• Rising care costs

By adhering to MRR requirements, you protect residents and strengthen your facility’s reputation for delivering evidence-based care.

Key Focus Areas During Reviews

During the monthly medication reviews, pharmacists should assess:

• Duplicative therapies

• Incorrect duration or dosage

• Lack of monitoring for lab abnormalities or side effects

• Consistency between prescribed medications and documented diagnoses

These reviews should be aligned with the resident’s care plan and coordinated with other tools such as the Minimum Data Set (MDS).

Best Practices for Compliance and Quality Improvement

To stay ahead of regulatory scrutiny and improve care quality, senior care decision-makers should:

• Foster interdisciplinary communication between pharmacists, nurses, and physicians

• Implement integrated electronic health records (EHRs) for transparency and efficiency

• Invest in ongoing staff education on CMS medication standards

Final Thoughts

42 CFR 483.45 isn’t just another checklist item, it’s a strategic opportunity to prevent harm, promote better outcomes, and demonstrate your facility’s commitment to high-quality, person-centered care.

Ensuring proper implementation of Medication Regimen Reviews is more than regulatory, it’s the right thing to do for the seniors entrusted to your care.
