Implementation Science and Opioid Overdose Prevention 

When the FDA approved OxyContin in 1995, it brought much-needed relief to people living with severe pain from injuries, surgeries, cancer and chronic illnesses. But this highly addictive medication also fueled an opioid crisis that continues to devastate communities across the United States. 

Understanding the Opioid Crisis: Why Overdose Education Matters 

Imagine someone collapses in front of you. Their skin is pale, lips are blue and they’re barely breathing — signs of a possible opioid overdose. In that moment, every second matters. 

American opioid overdose deaths increased by a staggering 400% between 1999 and 2013. Veterans in particular were at high risk, prompting the Department of Veterans Affairs (VA) to launch Overdose Education and Naloxone Distribution (OEND) programs at VA medical centers: first in pilot locations, and then in every VA facility. 

What Is Naloxone? 

Naloxone, better known by the brand name Narcan, is a medication that blocks the effects of opioids — like fentanyl, morphine, oxycodone and heroin — within minutes. It comes in a simple nasal spray form, making it easy for anyone to use. Naloxone is safe, requires no medical training and won’t harm someone who isn’t overdosing.  

How OEND Programs Use Implementation Science to Prevent Opioid Overdose 

Implementation science is the process of taking proven ideas — like naloxone education — and making sure they work in real-world settings. In 2013, the Department of Veterans Affairs began using this approach to teach healthcare providers, patients and community members how to recognize an overdose and use naloxone to save lives. 

What Are the Benefits of OEND Programs? 

Overdose Education and Naloxone Distribution programs can: 

• Train people to respond quickly to opioid overdoses. 
• Distribute naloxone kits to those at the highest risk for overdose. 
• Raise awareness about opioid safety and prevention. 

VA Connecticut’s OEND Pilot: One Opioid Overdose Prevention Success Story  

The VA Connecticut Healthcare System (VACT) was one of the first to pilot an OEND program. In 2015, a multidisciplinary team from the hospital trained staff and providers, educated veterans in substance use treatment programs and handed out naloxone kits with vials, syringes, atomizers and clear instructions. 

Even though it was a small start, the results were powerful, and the pilot program revealed key insights. 

Lessons From the VA Connecticut OEND Pilot 

• Some staff believed only mental health professionals should distribute Naloxone: an early barrier that had to be challenged. 
• More than 500 kits were distributed within a year, showing strong demand and engagement. 
• Not only was it possible to implement such a program, it could also be scaled to reach more people and save more lives. 

How OEND Expanded Beyond the VA 

Following the VA’s lead, OEND programs expanded to non-military populations across the country. Today, you can find these programs in state health departments and community outreach centers. The VA continues to support veterans with free naloxone kits, overdose prevention resources and training materials in multiple languages. 

In 2023, a major milestone was reached: Narcan was approved for over-the-counter sales, making it easier than ever to access. 

We’ve Come a Long Way — But the Crisis Isn’t Over 

Thanks to efforts like these, naloxone has saved many lives. It’s credited with a 24% decrease in U.S. drug overdose deaths from 2023-2024. 

A naloxone distribution program is believed to have saved more than 103,000 lives in Tennessee alone between 2017 and 2024. That’s a big win — especially in an area hit hard by opioid abuse. 

Still, the crisis continues, especially with the rise of synthetic opioids like fentanyl. Widespread education, access and awareness are now even more crucial. 

How You Can Help in an Opioid Overdose 

If you or someone you love uses high-dose opioids — prescribed or otherwise — carrying Narcan, just like someone with a severe allergy carries an EpiPen, could save a life. And with over 100,000 U.S. pharmacies carrying it (including generic versions), you can access it quickly when needed. 

Key Takeaways: 

• Prescription opioids helped spark the ongoing U.S. opioid crisis. 
• The VA’s OEND programs, backed by implementation science, paved the way for broader naloxone distribution. 
• Narcan’s over-the-counter approval in 2023 made it more accessible than ever. 
• Naloxone saves lives — but more outreach and education are needed to fight this epidemic.
