Conclusions

3

Consider these questions

How would your hospital respond to an emergency involving radiation?

Would you know if a patient in your ER was contaminated with radioactivity?

Could you provide lifesaving patient care and also keep your staff and facility safe?

4

How should your staff to react to a radiological incident?

Like this? Or like this?

5

MOTIVATION

6

Motivation

The potential for an incident involving injured patients and radioactive materials is growing due to:

 industrial and medical use of radioisotopes

 worldwide increase in terrorist activities

 renewed interest in nuclear energy

7

Contaminated

Patients

Individuals involved in such incidents may be contaminated with radioactive materials and, if injured, will require emergency medical treatment.

D. Morse, Armed Forces Radiobiology

Research Institute (AFRRI)

8

Would you Know

Radiation is Involved?

First responders transporting patients may not know that the incident involved radiation.

Contaminated patients may self present for medical care.

Without independent radiation detection capability, a hospital emergency center won’t necessarily know if a radiation hazard exists.

9

What is Needed?

A Radiological Incident Response plan that includes the following:

 technical capabilities to detect, measure, and identify sources of radiation

 procedures for staff to follow

Demonstration

Project

The Division of Public Health solicited applications from hospitals to conduct a demonstration project implementing the recommendations of that report.

Gundersen Lutheran Health System was selected.

14

Gundersen Lutheran

Health System

Headquartered in

La Crosse, WI

Serves patients throughout 19 counties in western

Wisconsin, northeastern Iowa, and southeastern

Minnesota

15

Trauma & Emergency

Center (TEC)

Level II Trauma and Emergency

Center serves over 30,000 patients/yr

18-bed unit staffed by 11 emergency medicine physicians and 70 nurses, EMTs, paramedics, and other personnel

16

HAZARD VULNERABILITY ANALYSIS

(HVA)

17

First Step - HVA

Our first step was to conduct a Hazard

Vulnerability Analysis

Purpose of HVA: identify factors that could increase the risk of a radiological incident in the region

18

HVA Results

• location on a major interstate highway;

• proximity to a nuclear reactor currently being decommissioned

• proximity to U.S. Army’s Fort McCoy

• radioactive material use at local hospitals, universities, industrial facilities, and government facilities

Potential radiological incidents related to these factors include transportation accidents, worker injuries, and terrorist actions.

19

EVALUATION OF EXISTING SPACE AND

EQUIPMENT

20

What Were We Starting

With?

An evaluation of the existing space and equipment was conducted in collaboration with outside experts in chemical, biological, radiological, and nuclear (CBRN) response

21

Outside Experts

Exchange program conducted with Frimley Park

Hospital NHS Foundation Trust in the United

Kingdom.

Similar to Gundersen Lutheran in size, proximity to major transportation routes, and proximity to a large military base

Equipment Storage

Containers

Plastic storage containers that could be easily lifted and moved were used to store equipment and

PPE right in

Decontamination room.

Subsequently obtained wheeled storage unit to hold all containers. Easy to move out when Decon Rm needed.

71

TRAINING

72

Training

Key factors for selecting training materials and methods:

 cost

 time required ease of use in an emergency situation (“just in time” training)

73

Training Program

Selected

The 17-minute CDC video Radiological Terrorism: Justin-Time Training for Hospital Clinicians , was the primary training tool.

Intended for medical staff but found to be applicable to non-medical staff too.

Feedback indicated video made staff more comfortable with providing care to a contaminated patient and reduced their fear of radiation and radiation effects.

74

Training

Staff also received training on the specific steps and actions in our Radiological Incident

Response Plan.

Hands-on training provided to TEC staff in use of radiation survey meters and response if the alarms trigger on the area monitors at the TEC entrances.

Annual refresher training and updates done via intranet course and in-person inservices.

75

TESTING

76

Testing

Three exercises were performed to test the

Radiological Incident Response Plan.

 each exercise tested different parts of the plan.

 drill observer recorded observations and recommendations during exercise

 drill photographer

Post-drill recommendations implemented and retested in next exercise

77

Exercise 1: U.S. Army

Operation Red Dragon

2009

Operation Red Dragon conducted by U.S. Army

Reserve personnel.

• Focused on the military’s ability to deploy Army

Reserve chemical assets in a CBRN response environment in coordination with local community agencies and hospitals.

78

Red Dragon

Scenario

Terrorist group detonates improvised explosive device – shaped charge on a pressurized container aboard a barge near the La Crosse festival site, releasing anhydrous ammonia during a major morning concert and festival.

Terrorist group then targets the victims and the emergency responder community by releasing a radiologic agent from a nearby bridge.

Potential 28484 exposures, 1208 untreated fatalities, and

1342 total casualties, overwhelming medical and public health authorities and decimating emergency responders.

79

Operation Red Dragon

80

81

Exercise 2:

Radiopharmaceutical courier transportation accident

Scenario: A courier vehicle delivering nuclear medicine isotopes to area hospitals plunges over an embankment on the interstate highway.

• First responders observe the “Caution – Radioactive

Materials” signs on crushed and wet packages. Notify

TEC they will arrive in 30 min with one non-ambulatory patient with a fractured arm who may be contaminated with radioactive materials.

Limited drill. Ended when simulated patient brought into

Decontamination Room.

82

Radiopharmaceutical courier transportation accident

83

84

Exercise 3:

131

I patient

Scenario: Patient receives 100 mCi radioactive 131 I for treatment of thyroid carcinoma at another regional hospital.

An hour later, while returning home by car she develops a severe headache, nausea, and vomiting. Her husband pulls the car over and calls 9-1-1. First responders arrive.

Patient loses consciousness on the way to the hospital and is taken directly to a treatment room. Police officer from the scene is unaware that he is contaminated with

131 I and triggers the TEC entrance radiation detector.

87

STAFFING AND WORKLOAD

IMPLICATIONS

88

Staffing/Workload

Implications

Staff were used in their existing job roles, and no additional personnel were required for this project.

Staff time was required to:

• develop the plan and associated documents

• train staff

• develop and participate in the three exercises

89

Staffing/Workload

Implications

Concise training methods resulted in 1-4 hour training time for each participating TEC staff member including exercises

The most significant time burden was that of the facility’s Radiation Safety staff. 80-100 total hrs

90

CONCLUSIONS

91

Factors for Success

A plan champion (the Radiation Safety Officer) and the core group of individuals who took responsibility for developing and implementing the plan were critical to the success of this project.

Incorporating use of the ICS provided sufficient flexibility to adapt to any size of radiological emergency

92

Factors for Success

Combination of video training, hands-on training, and practicing actions in exercises was an effective system of education for individuals with differing learning styles.

Clear, concise Job Action Cards received very positive feedback from staff.

93

Challenge

Limitations in Gundersen Lutheran Health

System’s existing decontamination facilities were a challenge.

The lesson learned from this challenge is that hazardous materials incident response should be incorporated into planning new construction

94

Challenge

Conducting exercises was challenging because an ER is busy with real patients.

Consulting with emergency center staff to determine the best time to conduct a drill was useful.

Conducting limited exercises to test specific parts of the plan was better for ER staff than a 3-

4 hr full drill

95

.

Conclusions

Successfully demonstrated that the Wisconsin State

Expert Panel on Radiation Emergencies report entitled

The Management of Patients in a Radiological Incident issued in November 2007 provides a flexible template that can be customized to fit the needs of individual healthcare organizations.

Cost of implementation was approximately $25,000, not including staff time

Readiness for appropriate response to an actual radiological incident was substantially improved.
