Summary
Medication nonadherence significantly increases US healthcare costs, particularly for chronic conditions like diabetes and asthma. Addressing this requires understanding adherence impacts and exploring new strategies like e-prescribing.
Area of Science:
- Public Health
- Health Economics
- Pharmacoeconomics
Background:
- Medication nonadherence is a significant public health issue with substantial impacts on patient outcomes and healthcare expenditures.
- Understanding the economic burden of nonadherence is crucial for developing effective interventions within the US healthcare system.
Purpose of the Study:
- To review recent advancements in medication adherence research.
- To analyze the impact of medication adherence on healthcare costs in the US.
- To explore mechanisms linking nonadherence to increased costs and discuss trends like e-prescribing.
Main Methods:
- Literature review focusing on adherence research and healthcare costs.
- Analysis of nonadherence impact across chronic diseases (e.g., diabetes, asthma).
- Discussion of research study designs and future research directions.
Main Results:
- Medication nonadherence contributes significantly to overall healthcare costs.
- Specific chronic diseases like diabetes and asthma demonstrate substantial cost increases due to nonadherence.
- Various mechanisms link nonadherence to elevated healthcare expenditures.
Conclusions:
- Addressing medication nonadherence is essential for mitigating healthcare costs.
- Emerging trends such as pharmacist-led medication therapy management and electronic prescribing offer potential solutions.
- Further research is needed to optimize adherence strategies and reduce the economic burden.

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...
