Active Shooter and Intentional Mass-Casualty Events: The Hartford Consensus II

Concept to action

On April 2, representatives from a select group of public safety organizations including law enforcement, fire, pre-hospital care, trauma care, and the military convened in Hartford, CT, to develop consensus regarding strategies to increase survivability in mass-casualty shootings. A concept document resulted and became known as the Hartford Consensus. It includes an acronym to describe the needed response to active shooter and intentional mass-casualty events. The acronym is THREAT:

• Threat suppression
• Hemorrhage control
• Rapid Extrication to safety
• Assessment by medical providers
• Transport to definitive care

Within the framework of THREAT, there exists the opportunity to improve survival outcomes for the victims of active shooter and intentional mass-casualty events through mutual collaboration and reinforcing responses. The Hartford Consensus stipulates that medical training for external hemorrhage control techniques is essential for all law enforcement officers. They should play a key role as the bridge between the law enforcement phase of the operation and the integrated rescue response. The interval from wounding to effective hemorrhage control can be minimized by law enforcement officers trained in hemorrhage control. This principle is central to the findings of the first Hartford Consensus. The purpose of the Hartford Consensus Conference II, which took place July 11 in Hartford, was to develop strategies for focused actions to achieve the objectives of the first Hartford Consensus.

Fundamental concepts

To maximize survival from an active shooter or an intentional mass-casualty event there must be a continuum of care from the initial response to definitive care. The essence of this continuum involves the seamless integration of hemorrhage control interventions. This process starts with the actions of the uninjured public or minimally injured victims and extends to the first responding law enforcement officers, then to EMS/fire/rescue personnel, and ultimately to definitive trauma care. These concepts must be scalable to facilitate implementation in communities of all sizes. The law enforcement response has evolved from the original concepts of “surround and contain” to a more modern and aggressive response. EMS/fire/rescue must be involved earlier in the care of these victims. They should have direct contact with the law enforcement personnel on the scene.

Call to action

No one should die from uncontrolled bleeding. Preventable death after an active shooter or an intentional mass-casualty event should be eliminated through the use of a seamless, integrated response system. Each group in the following categories should perform the actions necessary to accomplish this goal:

Public: Uninjured or minimally injured victims can act as rescuers. Everyone can save a life.

• Recognize that the initial response to an intentional mass-casualty event will be from uninjured bystanders and minimally injured victims
• Design education programs and implement training for a public response to an active shooter or intentional mass-casualty event
• Pre-position necessary equipment in appropriate locations
• Recognize that in an active shooter event the education message should include the concept of “Run, Hide, Fight”

Law enforcement: External hemorrhage control is a core law enforcement skill.

• Identify appropriate external hemorrhage control training for law enforcement officers
• Ensure appropriate equipment, such as tourniquets and hemostatic dressings, is available to every law enforcement officer
• Ensure assessment and triage of victims with possible internal hemorrhage for immediate evacuation to a dedicated trauma hospital
• Train all law enforcement officers to assist EMS/fire/rescue in the evacuation of the injured

EMS/fire/rescue: The response must be more fully integrated and traditional role limitations revised.

• Train to increase awareness and operational knowledge about the initial response to an active shooter or intentional mass-casualty eventIncorporate Tactical Combat Casualty Care and Tactical Emergency Casualty Care concepts into EMS/fire/rescue training
  • It is no longer acceptable to stage and wait for casualties to be brought out to the perimeter.
  • Training must include hemorrhage control techniques, including the use of tourniquets, pressure dressings, and hemostatic agents.
  • Training must include assessment, triage, and transport of victims with potentially lethal internal hemorrhage and torso trauma to definitive trauma care.
• Modify the response doctrine to improve the interface between EMS/fire/rescue and law enforcement in order to optimize patient care
• Establish a common language for responders, permitting each community to improve coordination, develop concurrent response, and establish mutually acceptable levels of operational risk between all public safety professionals to enhance the defense, rescue, treatment, extrication, and definitive care of survivors

Definitive trauma care: Existing trauma systems should be used to optimize seamless care.

• Provide trauma care to victims of an active shooter or an intentional mass-casualty event based on available resources and the establishment of mitigation strategies that acknowledge community limitations
• Design, implement, and practice plans to handle a surge in patient care demand from an active shooter or an intentional mass-casualty event

Education

To achieve the goals of this call for action, education of all groups is required. The core Hartford Consensus concepts should not be limited to traditional public safety responders. Everyone can and should be an initial responder. Education should be tailored to the level of the responder. Everyone should be taught hemorrhage control. Professional first responders should also be taught airway management. Education for the patient care process should focus on THREAT and include:

• Rapid access to hemorrhage control
  • External hemorrhage control
    • Direct pressure
    • Tourniquet application
    • Hemostatic agents
  • Internal hemorrhage control
    • Rapid transportation and access to a trauma center
    • Prompt access to the operating room
    • Incorporation of new concepts in hemostatic resuscitation and damage control surgery that have been used successfully in recent military conflicts

Evaluation

With this significant change in approach to an active shooter or an intentional mass-casualty event, a carefully conceived evaluative process to determine the efficacy of THREAT is warranted. Scientific evaluation of the implementation of Hartford Consensus concepts must ensure that future efforts are focused on ideas that are effective.

The evaluation process should include measurement of the following:

• Accessibility of field hemorrhage control equipment for law enforcement, EMS/fire/rescue, and the general public
• Documentation of the use of hemorrhage control equipment by law enforcement, EMS/fire/rescue, and the general public
• Submission of relevant data to a national registry
• Analysis of the quantitative and qualitative aspects of the data submission process to a national registry
• Use of THREAT training guidelines by all relevant providers
• Integration of operational doctrine through policy development and enabling legislation across the country relevant to law enforcement, EMS/fire/rescue
• Compliance and efficacy of the after action report process
• Effectiveness of THREAT educationReduction of preventable death
  • Effectiveness of THREAT implementation
  • Effectiveness of threat suppression
  • Timelines and appropriateness of initial hemorrhage control
  • Timeliness and effectiveness of rapid extrication
  • Transportation to and interface with definitive care facilities
  • Readiness of definitive care facilities for control of internal hemorrhage
• Local, regional, and national performance to identify opportunities for improvement and gaps in funding for research and development

Coalition of stakeholders

To achieve the goals of this call to action, a coalition of stakeholders must be established. To do so, the following must be accomplished:

• Identify core national leaders
• Establish a communication plan for the widespread dissemination of THREAT
• Identify legislative priorities
• Engage in the legislative process at the national and state levels
• Engage in funding initiatives
• Implement pilot projects to demonstrate the effectiveness of the action principles of the Hartford Consensus
• Partner with relevant groups including national, federal, state, law enforcement, fire, EMS, medical, nursing, military, professional, and voluntary organizations (see sidebar)

Conclusion

The Hartford Consensus II has generated a call to action in order to enhance survival from active shooter or intentional mass-casualty events. The call to action engages the public, law enforcement, EMS/fire/rescue, and definitive care facilities. It embodies the principles of THREAT and calls for modification of the initial responses to these events. A broad educational strategy and a robust evaluation of the implementation of THREAT are needed to quantify the benefits of this approach to the management of active shooter and mass-casualty events.
