According to a new Vital Signs report released by the Centers for Disease Control and Prevention (CDC), approximately 5 million Medicare Part D enrollees aged 65 and older are failing to take their blood pressure medication as directed, heightening their risk of heart disease, stroke, kidney disease, and death.
The Growing Public Health Challenge of Uncontrolled Hypertension
High blood pressure remains a pervasive danger across the United States. Data indicates that seven out of ten U.S. adults aged 65 and older live with hypertension, defined clinically as readings of 140/90 mmHg or higher. Yet, nearly half of this vulnerable population fails to keep their condition under control.
The consequences of leaving hypertension unmanaged are severe. The CDC and Centers for Medicare & Medicaid Services (CMS) analyzed data from more than 18.5 million individuals enrolled in Medicare Advantage or Original Medicare with Part D prescription drug coverage during 2014 to map these gaps in medication adherence.
“A simple action can avoid potentially deadly consequences: take your blood pressure medicine as prescribed,” stated CDC Director Tom Frieden, M.D., M.P.H.
In Plain English: The Clinical Takeaway
- Adherence Matters: Not taking blood pressure medicine as directed means patients may skip doses or stop taking it altogether.
- The Target Threshold: Control is defined as blood pressure less than 140/90.
- Systemic Support: Nationwide blood pressure control can be significantly enhanced through the combined efforts of health care systems, which encompass hospitals, insurers, practices, community health workers, nurses, doctors, and pharmacists.
Geographic and Demographic Disparities in Medication Adherence
The federal report highlights demographic and regional divides regarding who takes their prescribed medications. Medicare Part D enrollees belonging to specific racial and ethnic groups—including American Indian/Alaska Native, Black, and Hispanic populations—exhibit higher rates of non-adherence. This contributes to these groups’ higher risk of heart attack, stroke, kidney disease, and death.
Geographically, southern U.S. states, Puerto Rico, and the U.S. Virgin Islands report the highest overall rates of not taking blood-pressure medicines as directed. Conversely, states like North Dakota, Wisconsin, and Minnesota demonstrate the highest rates of people who do take their medicine as directed.
| Metric | Statistic |
|---|---|
| U.S. Adults Age 65+ with Hypertension | About 70% |
| Proportion Controlled (<140/90 mmHg) | Roughly 50% |
| Medicare Part D Enrollees Not Taking Meds as Directed | Approximately 5 million |
“While the Medicare prescription drug program has increased the affordability and accessibility of prescription drugs, more can be done to encourage Medicare beneficiaries to take their medications as directed,” noted Sean Cavanaugh, CMS deputy administrator and director of the Center for Medicare. Federal initiatives, including the Medicare Star Ratings program, continue to encourage prescription drug plans to improve medicine use.

Pathways Forward for Health Care Systems
Addressing this adherence crisis requires a coordinated response from the medical ecosystem. Insurers, nurses, pharmacists, and physicians must proactively connect with patients to convey why blood pressure management is vital and how following a healthy diet and exercise routine alongside proper medication usage diminishes the threat of stroke, kidney disease, and heart disease. Through targeted community interventions and federal resources provided to all states and Washington, D.C., clinical teams aim to bridge the gap between prescription and protection.
