Research on case definitions for BioSense program Evaluation of BioSense Program Community assessment of non-pharmaceutical interventions to prevent influenza Training needs assessment of federal partners who may support quarantine efforts Health Security and Systems Research: Current Portfolio
Evaluation of the Medical Reserve Corps Rapid response team for public health research on disasters Focus of today’s talk: Patient Tracking & Locating Model Cyanide K/A/P among EMS providers Health Security and Systems Research: Current Portfolio (cont.)
Poll Question In disaster response, patient tracking and locating systems are: A. Very important B. Important C. Moderately important D. Not at all important
Role for Patient Tracking and Locating System • Identify persons in need • Locating missing persons • Allocating medical resources • Conducting public health interventions • Managing emergency shelters • Evacuating patients
Background on PTLocator • Agency for Healthcare Research and Quality (AHRQ) provides support • Conceived in 12/2004 • Work began 08/2005 • Review of extant products • EMSystem • Ratheon • Dept. of Defense projects
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
Issues Facing Use of PTLocator • Data exchange across systems using XML—need for standards • Deployment during emergencies • Duplicate entries • HIPPA • Other privacy protections, esp. with public searches
AHRQ Companion Projects • Patient Tracking and & Locating Model • HAvBED hospital bed tracking system • Facility evacuation tool for estimating time and resources needed to evacuate a hospital
Cyanide Knowledge, Attitudes, andPractices among EMS providers
Poll Question What is the highest risk of cyanide poisoning? A. Fire B. Industrial release C. Release in transport D. Terrorism
Cyanide Poisoning as a Public Health Issue • 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: 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
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.
Methods Design: • Cross-sectional survey • Questionnaire administered via the Internet, mail, or telephone Sample: • Target population: all advanced life support (ALS) emergency providers working with fire departments in the U.S. • Sample frame: 22,524 fire departments identified through US Fire Administration’s National Fire Department Census • Sample of 1,033 fire departments randomly selected from sampling frame • 832 ALS providers surveyed • 507 evaluable surveys completed

Criteria for Estimating Likelihood of Cyanide Exposure • Fire-smoke injury rates per 100,000 • No. CERCLIS (Superfund) sites • No. Au, Ag, Cu mines • No. EPA Toxic Release Inventory (TRI) facility counts (for select CN chemicals) • Max. amt. TRI select CN chemicals, in lbs.

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…
