Topic Collection: Pre-Hospital Patient Decontamination
Caring for patients on the scene of an incident who have been contaminated by a hazardous material calls for strict planning to protect both the patient and the responder. The resources in this Topic Collection include guidelines, courses, exercises, and lessons learned from past events that can help emergency healthcare providers better plan for, and respond to, hazardous materials incidents. In addition to these resources, providers are encouraged to contact local poison control centers during an event for real-time access to expertise and additional databases and information sources than are available in the field.
This Topic Collection was refreshed in 2022. Each resource in this Collection is placed into one or more of the following categories (click on the category name to be taken directly to that set of resources). Resources marked with an asterisk (*) appear in more than one category.

The authors evaluated the clinical and operational effectiveness of PRISM through an exercise and found that the triple combination of dry, ladder pipe system, and technical decontamination attained an average decontamination efficiency of approximately 100% on exposed hair and skin sites.

The Primary Response Incident Scene Management (PRISM) series is comprised of three volumes that can help ensure that patients exposed to potentially hazardous chemicals receive the most effective treatment possible during the initial stages of an incident (after prompt decontamination). Updated in 2019, PRISM incorporates new scientific evidence on emergency self-decontamination, hair decontamination, the interactions of chemicals with hair, and the effects of a combined decontamination strategy referred to as the “triple protocol.” The clinical research showed that these three steps, taken together, remove 99.9 percent of chemical contamination.

The authors summarize the emergency medical services response to the attack, including challenges and strengths. They recommend that responders have access to mobile decontamination facilities in similar events. Chemical effects on responders were significant. Though many effects were psychogenic in nature, the mere perception of harm rendered responders less effective (another reason why responder access to personal protective equipment for chemical events is so important).

This article discusses an exercise in Milan, Italy, in which buses and a tent were used by healthcare and emergency preparedness staff to simulate decontamination during a biological, chemical, or radiation incident. While the buses proved to be practical for several reasons, the authors listed challenges associated with limited capacity, non-ambulatory patients’ access to the buses, and other issues.

Event-Specific Lessons Learned
The authors reviewed field exercise data collected during a mass decontamination exercise. They found that the "bottleneck" in the process was the re-dressing or re-robing of patients after they had showered. They suggested strategies for addressing this challenge, including shorter showers and more people showering at one time. ASPR TRACIE subject matter expert reviewers suggest, however, that shorter showers may be less effective, and recommend additional space for re-dressing. This article does effectively convey that “real-world” decontamination will experience bottlenecks—some of which can be anticipated and some of which will require adaptation during the event. Availability of “dry decontamination” / redress kits for those with minimal/no symptoms may help prevent bottlenecks in the gross/technical decontamination process.

The authors reviewed the literature on chemical decontamination in a mass casualty scenario, based on research in vitro and in human volunteers. The authors emphasize the importance of beginning decontamination immediately/removing contaminated clothing and examine the effectiveness of wet and dry decontamination interventions. They also suggest several areas for future research, including chemical vapors, determining safe chemicals to use with human volunteers, and improving assessment of exposure and risk communication.
