Medication Safety Basics
The Medication Safety Program, housed in the Division of Healthcare Quality Promotion (DHQP), leads CDC’s national adverse drug events (ADEs) surveillance activities and seeks to translate population-based surveillance data into evidence-based policies and targeted, innovative and collaborative interventions.
Adverse drug events (ADEs) are a serious public health problem. It is estimated that:
- 82% of American adults take at least one medication and 29% take five or more 
- 700,000 emergency department visits and 120,000 hospitalizations are due to ADEs annually 
- $3.5 billion is spent on extra medical costs of ADEs annually 
- At least 40% of costs of ambulatory (non-hospital settings) ADEs are estimated to be preventable 
The numbers of adverse drug events will likely grow due to:
- Development of new medications
- Discovery of new uses for older medications
- Aging American population
- Increase in the use of medications for disease prevention
- Increased coverage for prescription medications
