Pharmacists Improve Patient Health Through Medication Reviews

National Check Your Meds Day, observed on October 21, is an important annual reminder of the value of these pharmacist-led interventions.

In the evolving landscape of health care, pharmacists are increasingly being recognized not just as dispensers of medication but as vital health advocates. One of the most impactful, yet often overlooked, ways pharmacists contribute to patient safety and public health is through comprehensive medication reviews.

“Do you know what each of your prescriptions is for?” “Are you taking your medications as directed?” “Do you have access to reliable transportation to your pharmacy?”

These are common questions in our profession as pharmacists. These simple questions can make a real difference in spotting and closing gaps in care, increasing medication adherence, and improving the whole health of our patients. As pharmacists, we are key players within a patient’s health team, advocating for safer, smarter medication use.

The Centers for Disease Control and Prevention (CDC) reports that nearly 70% of adults ages 40-79 say in the past 30 days they’ve used at least 1 prescription medication, and in the past 30 days, more than 22% report using 5 or more, a concept known as polypharmacy.1 Polypharmacy can significantly raise the risk of adverse drug events and medication errors. In addition to prescribed medications, we know many people also take over-the-counter drugs, vitamins, or supplements, often without disclosing these to their health care provider.

To make matters more complex, approximately 41% of patients in the US use more than 1 pharmacy, increasing the likelihood of uncoordinated care and missed drug interactions.2

The risks are real: nonadherence alone is estimated to cause 125,000 deaths annually and costs the US health care system nearly $300 billion in avoidable expenses. It also accounts for about 10% of hospitalizations.3

A medication review is more than a safety check. It is a clinical service that allows pharmacists to identify potential drug interactions, streamline therapies, recommend discontinuation of expired or unnecessary medications, find cost-saving alternatives, and, most importantly, engage with patients in conversations that improve their understanding, adherence, and safety.

For health care leaders, investing in pharmacist-led medication reviews is not just a clinical best practice; it’s a strategic imperative to improve patient outcomes, reduce avoidable costs, and strengthen the safety net across the continuum of care, particularly for patients with multiple chronic conditions.

About The Author

Lisa Morris, RPh, vice president and chief clinical officer at CarelonRx, leads the development and execution of clinical and specialty pharmacy benefit management strategies—driving quality, cost management, and drug utilization programs across commercial, Medicaid, and Medicare lines of business.

Pharmacists are uniquely positioned to spot gaps in care through medication reviews, as they are one of the most accessible healthcare professionals.4 In fact, about 90% of Americans live within 5 miles of a pharmacy.5 For those receiving pharmacy benefits, pharmacists in settings like CarelonRx are just a phone call away, expanding access even further. That accessibility can, and should, translate into action. Whether practicing in a community pharmacy, health system, or pharmacy benefits management organization, we must continue to include and support pharmacists as key leaders in optimizing medication therapy and improving health outcomes in our communities.

National Check Your Meds Day, observed on October 21, is an important annual reminder of the value of these pharmacist-led interventions. Every patient interaction is an opportunity to initiate a conversation that could prevent hospitalization, reduce costs, or even save a life.
