Current Version of PTL
Assumptions
Focus on identification of patient and location
Broad definition of patient/victim
System can serve at “national level” while also providing working model for “local” jurisdictions
Capabilities
Fully functional prototype accessible through Web
Manual Data Interface

![Page 20: RTI International is a trade name of Research Triangle Institute](https://reader030.vdocuments.mx/reader030/viewer/2022032709/56813039550346895d95d195/html5/thumbnails/20.jpg)
Poll Question
What is the highest risk of cyanide poisoning?
A. Fire
B. Industrial release
C. Release in transport
D. Terrorism
![Page 21: RTI International is a trade name of Research Triangle Institute](https://reader030.vdocuments.mx/reader030/viewer/2022032709/56813039550346895d95d195/html5/thumbnails/21.jpg)
Multiple, heterogeneous sources of human exposure
Fire smoke
Intentional poisoning: terrorism, genocide, murder, suicide
Industrial release
Occupational injuries
Transportation mishaps
Ingestion of cyanogenic foods, drugs
Mass casualties likely in either unintentional or intentional poisonings
Effective remediation possible through adequate preparedness, including ability to provide empiric prehospital treatment rapidly
Cyanide Poisoning as a Public Health Issue
![Page 22: RTI International is a trade name of Research Triangle Institute](https://reader030.vdocuments.mx/reader030/viewer/2022032709/56813039550346895d95d195/html5/thumbnails/22.jpg)
Cyanide Poisoning: Remediable Public Health Threat
Unlike toxicity associated with many other poisons,
cyanide poisoning can be effectively treated
Requires antidote and supportive care
Requires prompt intervention (within minutes to
hours) because of rapid progression of poisoning
![Page 23: RTI International is a trade name of Research Triangle Institute](https://reader030.vdocuments.mx/reader030/viewer/2022032709/56813039550346895d95d195/html5/thumbnails/23.jpg)
Study Objectives
To assess cyanide awareness, preparedness, and practices of emergency medical service (EMS) providers in the U.S.
To assess cyanide antidote stocking practices among EMS providers in the U.S.

Cyanide Study Conclusions
Fewer than half of EMS providers recognize fire smoke as the most likely source of CN exposure.
Only 15 percent report that an antidote is the standard treatment when cyanide poisoning is suspected.
Only 21 percent of ALS vehicles have cyanide antidote kits stocked.
There are only 25 antidote kits available per 100,000 persons, an inadequate number for a mass casualty event.

Closing Remarks
Working in public health preparedness at a not-for-profit institute:
Competitive, fast-paced environment
Mixture of investigator-initiated and contract work
Client satisfaction is high priority
Diverse activities—from software development to program evaluation to policy analysis
Multiple opportunities to make a difference
And finally…
