Natural disasters, industrial accidents, terrorism attacks, and pandemics all have the capacity to result in large numbers of critically ill or injured patients. This supplement provides suggestions for all of those involved in a disaster or pandemic with multiple critically ill patients, including front-line clinicians, hospital administrators, professional societies, and public health or government officials. The current Task Force included a total of 100 participants from nine countries, comprised of clinicians and experts from a wide variety of disciplines. Comprehensive literature searches were conducted to identify studies upon which evidence-based recommendations could be made. No studies of sufficient quality were identified. Therefore, the panel developed expert-opinion-based suggestions that are presented in this supplement using a modified Delphi process. The ultimate aim of the supplement is to expand the focus beyond the walls of ICUs to provide recommendations for the management of all critically ill or injured adults and children resulting from a pandemic or disaster wherever that care may be provided. Considerations for the management of critically ill patients include clinical priorities and logistics (supplies, evacuation, and triage) as well as the key enablers (systems planning, business continuity, legal framework, and ethical considerations) that facilitate the provision of this care. The supplement also aims to illustrate how the concepts of mass critical care are integrated across the spectrum of surge events from conventional through contingency to crisis standards of care.
Natural disasters, industrial accidents, terrorism attacks, and pandemics all have the capacity to result in large numbers of critically ill or injured patients.1 Depending on their magnitude, the response to these surges may vary from a conventional response, where critically ill patients are managed with no significant alterations in standards or process of care, to a crisis response, where resource limitations dictate significant alterations in both standards and process of care to provide minimal basic critical care to the maximum number of patients (Fig 1).2-6 This supplement provides suggestions for all of those involved in a disaster or pandemic with multiple critically ill patients, including front-line clinicians, hospital administrators, professional societies, and public health or government officials. Although it is important for all providers to be familiar with the aspects of critical care disaster/pandemic management, Table 1 provides an overview of the suggestions of most interest to each of the groups.
Figure Jump LinkFigure 1 – This figure depicts the spectrum of surge from minor through major. The magnitude of surge is illustrated by the alterations in the balance between demand (stick people) and supply (medication boxes). As surge increases, the demand-supply imbalance worsens. Conventional, contingency, and crisis responses are used to respond to the varying magnitude of surge. Varying response strategies are associated with each level of response. As the magnitude of the surge increases, the strategies used to cope with the response gradually depart from the usual standard of care (default defining the standards of disaster care) until such point that even with crisis care, critical care is no longer able to be provided.Grahic Jump Location

In 2008, the American College of Chest Physicians (CHEST) Task Force on Mass Critical Care published its first series of disaster critical care suggestions.1,5,7-9 Their published document reflected their consensus deliberations and proposed suggestions regarding the care of critically ill and injured patients from disasters. The supplement was received enthusiastically by both the medical and broader public health communities, becoming the second most frequently downloaded supplement from CHEST’s website, and papers from the supplement have been cited in 157 publications indexed on the Web of Science (http://thomsonreuters.com/web-of-science). The effort was timely, as many hospitals applied the suggestions to respond to regional crises related to the 2009 influenza A(H1N1) pandemic.10-16 Several recent disasters have brought new learning since the original documents were published. Also, the 2008 documents had minimal direction for the management of pediatrics, trauma, subspecialty ICU populations, or critical care outside of developed countries. Consequently, the Task Force for Mass Critical Care was reconvened with an expanded scope and expertise to provide a rigorously developed set of usable guidelines to critical care providers responding to disasters or pandemics throughout the world.
The assumptions1 upon which the first Task Force suggestions were based remain largely unchanged. Since 2008, the world has coped with the 2009 A(H1N1) pandemic as well as a myriad of other events that have either resulted in or have had the potential to create large numbers of critically ill patients or disrupt existing regional critical care infrastructure: Japan earthquake/tsunami 2011,17 Buenos Aires train crash 2012, Brazil night club fire 2013, Boston marathon bombing 2013,18,19 Spanish train crash 2013, super-storm Sandy,20,21 and the Westgate mall attack 2013 Nairobi. The horizon is studded with potential pandemics, such as H7N922 and MERS CoV23; in addition, conflicts and regional instability increase the risk of conventional and chemical weapons attacks.24-26 Clearly, hospitals and clinicians still need to be prepared to manage large numbers of critically ill or injured patients.
Cognizant of the burgeoning experience since the 2008 supplement, the Task Force for Mass Critical Care reconvened in 2012 and 2013 to review, update, and expand the suggestions presented in the 2008 supplement. In this iteration we have made a number of attempts to bolster the expertise of the Task Force itself as well as used a more rigorous methodology to develop the suggestions (see the “Methodology” article by Ornelas et al27 in this consensus statement). The current Task Force included a total of 100 participants (14 content experts, 68 panelists, and 18 topic editors) from nine countries, comprising clinicians and experts from disciplines including critical care, surgery, trauma, burn, pulmonary medicine, internal medicine, military medicine, disaster medicine, infectious diseases, hospital medicine, ethics, law, and public health, representing a diverse number of professions caring for both the adult and pediatric populations. Members of the Task Force were drawn from 15 different professional societies and organizations.
Our methodology had to recognize that there is still a paucity of high-quality evidence upon which to develop evidence-based recommendations for Mass Critical Care. The Task Force met in Chicago, Illinois in June 2012 to develop key questions. We then conducted comprehensive literature searches to identify evidence that could be used to answer the questions and provide evidence-based “recommendations.” Although some relevant studies were identified, none of the studies provided a sufficient quality of evidence upon which to make recommendations; therefore, expert opinion was solicited to provide answers (“suggestions”) to the key questions. To improve the rigor of the expert opinion, a modified Delphi process was used following the structure and guidelines established by the CHEST Guidelines Oversight Committee.27 All participants developing the Task Force’s suggestions (panelists and topic editors) were vetted through the CHEST conflict of interest policy.
The ultimate aim of the Task Force is to expand the focus to provide recommendations for the management of all critically ill adults and children resulting from a disaster or pandemic wherever that care may be provided, not solely the clinical management of critically ill patients within the walls of an ICU. Considerations for the management of critically ill patients include clinical priorities, logistics (supplies, evacuation, and triage), and the key enablers (systems planning, business continuity, legal framework, and ethical considerations) that facilitate the provision of this care. Finally, the supplement aims to illustrate how the concepts of mass critical care (MCC) are integrated across the spectrum of surge events from conventional through contingency to crisis standards of care (Figs 1, 2).2

The primary context for the Task Force’s suggestions remains health-care systems in the developed world. The language used throughout this supplement is not intended to refer to any one specific national context but rather should be viewed to be applicable in most large countries organized with a geographically based political structure incorporating a single national government with successive tiers of governments extending to local levels (Fig 3).28,29 Because the audience for these suggestions is those in resource-rich settings in developed countries, the Task Force has separately addressed the issue of mass critical care in resource-poor settings and provides suggestions to improve the provision of care in this context by strengthening existing systems and leveraging strategic relationships with world bodies and organizations from developed countries.

We provide a summary of the suggestions from the 13 articles included in the supplement. Please refer to the appropriate article for a detailed discussion of the suggestions.
Role of Critical Care in Disaster Planning
1. We suggest hospital and local/regional disaster committees include a critical care expert to optimize critical care surge capacity planning.
Surge Continuum: Conventional, Contingency, and Crisis Care
2. We suggest utilization of the existing framework for surge response that recognizes the shift in surge response across thresholds that distinguish conventional surge from contingency surge from crisis surge and delivery of crisis care is important in ensuring consistency in planning for critical care surge response.
Targets for Surge Response
3. We suggest in the presence of a slow onset, impending disaster/threat, targets for surge capacity and capability be focused, where possible, on projected patient loads.
4a. We suggest hospital critical care resources be able to expand immediately by at least 20% above the baseline ICU maximal capacity for a conventional response.
4b. In a contingency response, we suggest hospital critical care resources be able to expand rapidly by at least 100% above the baseline ICU capacity to meet patient demand using local and regional resources.
4c. We suggest hospital critical care resources be able to expand by at least 200% above baseline ICU capacity to meet patient demand in a crisis response using any combination of local, regional, national, and international resources.
5. We suggest more prolonged demands on critical care compared with the demands placed on other sections of the hospital (ie, days rather than hours) be taken into consideration when resuming routine hospital activities that may require ICU support.
Situational Awareness and Information Sharing
6. We suggest facilities, coalitions, and other components of the emergency response system, including those related to government entities, study how information about patients, events, and epidemiology are shared on a routine basis and during a major incident. Information technology (IT) should be leveraged to provide better indicators, more rapid alerting, and better patient data to facilitate decision-making.
7. We suggest the ability to provide dynamic forecasting of the functioning and sustainability of the supply chain be supported by hospitals.
Mitigating the Impact on Critical Care
8a. We suggest medically fragile patients be supported and protected by pre-event planning for ongoing medical support in the community to mitigate their reliance on hospital-based resources during a disaster event.
8b. We suggest local and regional authorities be responsible for integration of preventive community medical support in the plans to treat medically fragile patients during disasters.
8c. Given a situation where mitigation measures fail, medically fragile patients and victims of a disaster or pandemic should be given equal consideration for access to ICU resources.
Planning of Surge Capacity for Unique Populations
9a. We suggest regional planning include the expectation that the hospital be able to provide initial stabilization care to unique populations that they may not normally serve such as pediatrics, burn and trauma patients.
9b. We suggest access to regional expertise for care of all patients who require specialty critical care services including participation in the planning phase and access to just-in-time consultation for care coordination during a response.
Service Deescalation and Engineered Failure
10a. We suggest hospitals adopt a process of engineered systems cessation when the staff and/or material resources required for the ongoing critical care of a small number of patients could be used to save a greater number of lives.
10b. We suggest hospital cessation of the delivery of critical care services be considered if such endeavors are likely to entail significant personal risk to the treating team despite the availability of personal protective equipment and appropriate medical countermeasures.
10c. We suggest a hospital’s decision to restrict or expand the delivery of critical care be made as part of a local/regional decision-making process with consultation and input provided by hospital ICU leadership.
Stockpiling of Equipment, Supplies, and Pharmaceuticals
1. We suggest hospital support services, including pharmacy, laboratory, radiology, respiratory therapy, and nutrition services, also be included in the planning of critical care surge.
2. We suggest equipment, supplies, and pharmaceutical stockpiles specific to the delivery of mass critical care (MCC) be interoperable and compatible at the regional level and ideally at the state/provincial level, so as to ensure uniformity of response capabilities, coordinated training, and a mechanism for exchange of material among facilities.
3. We suggest facilities should ensure adequate availability of disaster supplies through facility-based caches, with vendor agreements and understanding of supply chain resources and limitations.
4. We suggest the existing MCC hospital target lists for basic equipment, supplies, and pharmaceuticals remain relevant for institutions seeking to plan for MCC response.
5. We suggest regional and hospital stockpiles include equipment, supplies, and pharmaceuticals that can be used to accommodate the needs of unique populations that are likely to require critical care in centers other than specialty care centers, including pediatric, burn, and trauma patients.
Staff Preparation and Organization
6. We suggest hospitals use adaptive measures to compensate for reduced staffing, such as additional shifts, workload, and changes in shift structure/time, should be planned in collaboration with the critical care staff representatives.
7. We suggest hospital staff preparation for response to a disaster is vitally important to the successful outcomes of such events and should include emphasis on role definition, integration with the incident command system, and the ability to perform cross-trained functions.
8. We suggest hospital staff preparedness to support critical care surge response include knowledge of the following: standard operating procedures, role definition, use of hospital incident command system, cross-training of additional staff, and training in the use of situational awareness tools, particularly those that can assist in decision-making regarding critical care surge planning, operations, response, and recovery.
9. We suggest once a disaster or pandemic has occurred, hospitals should implement measures to mitigate preventable causes of staff shortage, including sheltering of staff and their families, provision of mental health support, measures to mitigate fatigue, access to transportation services, and maintenance of a safe working environment.
10. We suggest critical care nurse-to-patient ratios in an event requiring critical care surge be determined by provider experience, available support (ancillary staff), and clinical demands.
11. During a disaster or pandemic, we suggest critical care physician oversight and direction of the clinical care teams who provide critical care services, including scheduled patient assessment and treatment plan evaluation. If direct oversight is unavailable, a means of remote consultation should be used.
12. Should expert consultation (eg, pediatrics, trauma, burn, or critical care) not be available locally, we suggest every effort be made by hospitals to ensure that such expertise be provided at a minimum through remote consultation.
13. We suggest hospitals consider the utilization of technology (eg, telemedicine) as an important adjunct to the delivery of critical care services in a disaster to serve as a force multiplier to support response to disaster events. Where no such systems are currently in place, development of a telemedicine or other electronic platform to support patient care delivery is suggested.
Patient Flow and Distribution
14. We suggest decisions regarding in-hospital placement of critically ill patients during an MCC (after initial survey and treatment) be performed by an experienced clinician who makes similar triage decisions on a daily basis.
15. Early discharge of ICU patients to the general ward is a complex process, requiring critical care expertise. To enable rapid admission of critically ill patients to the ICU immediately after termination of ED/operating room workup and treatment, we suggest discharge of ICU patients (when possible) during preparation for an impending MCC be given priority simultaneous to decisions made about initial ED patient distribution.
Deployable Critical Care Services
16. We suggest deployable critical care services be considered a temporary alternative to critical care when loss of hospital infrastructure limits provision of critical care.
17. We suggest deployable critical care services are not definitive critical care facilities but may be used as a temporizing measure for delivery of critical care in a disaster setting. Expansion of critical care resources in the hospital environment, with temporary facilities for lesser acuity patients, is preferred over provision of deployable critical care when possible.
18. We suggest deployable critical care services may serve as temporary critical care locations provided there is a clear plan for patient transfer, within a few hours to days, to a definitive treatment location.
19. In crisis surge response, we suggest less intensive treatment of moderately injured patients be prioritized over the deployment of temporary critical care services when it would result in improved outcomes for larger numbers of patients.
Using Transportation Assets to Support Surge Response
20. We suggest surge capacity plans include predetermined standards that define minimal ongoing critical care capability in order to define the framework for decisions regarding patient transfer as the demands on the system gradually increase during a disaster or pandemic.
21. We suggest priority be given to transfer of assets to patients, particularly when transfer of patients to definitive care is limited by dangerous conditions (including considerable risk posed by available transportation options).
22. Transportation used for patient evacuations may also be used to bring in assets (eg, specialty providers and equipment), particularly when access/transport capacity is the limiting factor in patient movement.
Form Hospital and Transport Agreements
1a. We suggest local and regional mutual-aid agreements should be established with other appropriately staffed and resourced hospitals to redistribute critically ill and injured patients from an evacuating hospital(s), and these agreements should be integrated within the framework of disaster preparedness plans.
1b. We suggest creation of predisaster formal agreements between hospitals and transport agencies or between Health Coalitions or Regional Health Authorities and transport agencies for air or ground transport of critically ill patients during a disaster.
Prepare for and Simulate Critical Care Evacuation
2a. We suggest staffing requirements within disaster plans should take into account the staffing resources necessary for desired surge capability to both safely move patients and to provide continuous care for patients remaining in the ICU.
2b. We suggest developing a detailed vertical evacuation plan using stairs when applicable for critically ill and injured patients.
2c. We suggest hospital exercises should simulate a mass critical care event and include vertical evacuation when applicable that evaluates (1) patient movement using specialized evacuation equipment and (2) the ability to maintain effective respiratory and hemodynamic support while moving down stairs.
Prepare for and Simulate Critical Care Transport
3a. We suggest specialized care is resource intensive, and specialized ground and aeromedical teams may be required to ensure appropriate initial and ongoing care prior to and during evacuation.
3b. We suggest preidentifying unique transport resources that are required for movement of specific populations, such as critically ill neonates, children, and technology-dependent patients, at a regional level. This information can then be used in real time to match allocated resources to patients.
3c. We suggest conducting detailed and realistic exercises that require ICU evacuation with local and regional ground and air transport agencies.
Designate a Critical Care Team Leader
4a. We suggest the Incident Management System at the evacuating ICU hospital should support early and frequent communication between Incident Command and a designated Critical Care Team Leader (CCTL) during an impending evacuation to provide close coordination and support of ICU evacuation preparations.
4b. We suggest the CCTL coordinating the critical care evacuation should be responsible for (1) categorizing ICU patients by ICU resource requirement and (2) communicating these ICU patient resource requirements with the Hospital Incident Command and to any Regional or National Emergency Command Center supporting hospital evacuation.
4c. We suggest when preparing for and during an ICU evacuation, a primary role of the CCTL should be to categorize each candidate ICU patient evacuee by (1) ICU resources required and (2) skill set of transport staff required.
4d. We suggest CCTLs and staff should receive special training, education, and practice on patient categorization and transport requirements.
4e. Expert providers from evacuation teams and outside facilities, when possible through face-to-face communication on site, can help ensure appropriate transport planning and distribution based on available resources during transport and in receiving facilities.
Initiate Pre-Event ICU Evacuation Plan
5a. If pre-event hospital evacuation of critically ill patients might be required, then we suggest planning for patient evacuation or shelter in place using an Incident Command System should begin as early as possible. Possible strategies include shelter in place, partial evacuation, or early evacuation, depending on the circumstances.
5b. We suggest Hospital Incident Command during a threatened hospital evacuation should have a clear and direct mechanism for communication with local governing bodies that control the timing and issuance of regional evacuation orders. To prevent obstruction of ground medical transport during hospital evacuation, coordination with local government regarding timing of recommendations for evacuation of the general population may be required. Efficient ground medical transport of patients during a hospital evacuation may be facilitated by providing a time period for hospital evacuation prior to recommendations for evacuation of the general population.
Requesting Assistance for Evacuation
6a. We suggest during a disaster or pandemic that overwhelms local and regional resources and requires large-scale hospital evacuations assistance, from national and/or international government medical support and evacuation agencies should be requested.
6b. We suggest the CCTL should be aware of the process for requesting evacuation assistance and the resources available at a regional and national level.
Ensure Adequate Power and Transport Ventilation Equipment
7a. We suggest surge ventilators with flexible electrical power and oxygen requirements should be available to support patients with respiratory failure that can maintain function while either (1) sheltering in place or (2) evacuating to an outside facility. These ventilators should be portable, run on alternating current power with battery backup, and have the ability to run on low-flow oxygen without a high-pressure gas source. Surge ventilators may be of limited capability but should be able to ventilate and oxygenate patients with acute lung injury or ARDS as well as airflow obstruction. This requires capability to deliver a high minute ventilation, high flow, and high positive end-expiratory pressure. They should be safe (disconnect alarm) and relatively easy for staff to operate.
7b. We suggest availability of adequate portable energy and medical gas flexible ventilators that can provide accurate small tidal volumes or pressure limits for the premature and neonatal patients expected at designated hospitals (for instance pediatric centers or hospitals with a neonatal ICU). Special consideration should be given to creating a standard, quickly accessible regional stockpile of mechanical ventilators for evacuation of neonatal patients as it may not be feasible for some nonpediatric centers to have adequate numbers of portable energy and gas flexible neonatal ventilators.
Prioritizing Critical Care Patients for Evacuation
8. We suggest evacuation order and identification of appropriate facility should be based on the following factors:
8a. In a time-limited evacuation, less critical patients can be evacuated faster and with fewer resources per patient and, thus, may be moved first in order to evacuate the most patients in the fastest time.
8b. When there is adequate time for evacuation, then more critically ill patients may be moved first and in parallel with less ill patients. Similar acuity patients often use similar transport resources and strain the same group of sending staff members. Thus, moving both the less critical and more critical patients simultaneously in parallel, as compared with sequentially in series (when there is adequate time to evacuate the entire hospital), may decrease the overall time to evacuation.
8c. In some situations, moving groups of similar-type patients to a single hospital entity may enable the sending hospital to provide staff to a single location to facilitate continuity of care and allow receiving hospitals to preplan to surge for specific types of patients and cluster disaster resources.
8d. The most critically ill patients dependent on mechanical devices for life support may, in some conditions, be safely cared for with a shelter-in-place strategy if it is deemed the risk of evacuation is too high.
Critical Care Patient Distribution
9a. We suggest during isolated, small, or pre-event ICU evacuations, CCTLs should coordinate with Hospital Incident Command and identify receiving hospitals for patient evacuation via the usual practice of provider-to-provider communication.
9b. We suggest during multiple-facility, large, or late ICU evacuations, the usual provider-to-provider system of communication for identification of receiving facilities should be augmented by other Regional or National Incident Management Systems.
9b.i. Every hospital should be specifically affiliated with (and drill evacuation with) a Regional or National Command Center for such events. Regional or National Command Centers may need to assume responsibility for designation of the receiving facilities for their patients.
9b.ii. We suggest when a Regional or National Emergency Command Center assumes responsibility for patient distribution, they should be responsible for identifying receiving facilities that match ICU patient resource requirements.
9b.iii. We suggest the Regional or National Emergency Command Center should enlist assistance of regional specialist experts to assist in the above matching process for distribution of patients requiring highly specialized care among receiving centers.
9c. We suggest assignment of transportation resources and lines of critical care patient evacuation should follow common existing referral patterns provided receiving facilities retain adequate capacity to care for these patients.
9d. We suggest patients who require advanced specialty care should be directed to high-volume centers and distribution take into account the capacity and resources required to provide ongoing care to these patients.
Preparing the Critical Care Patient for Evacuation
10a. We suggest standardized preparation of critically ill patients should be performed prior to hospital-to-hospital transfer, including initial stabilization, diagnostic procedures, damage control procedures, and medical interventions, to address anticipated physiologic changes during transport.
10b. We suggest the transport team should provide the equipment used for transport to ensure compatibility and familiarity during transport and retain important resources at the source institution for ongoing care of the remaining patients.
10c. We suggest evacuation planning and coordination should include the provision of additional expert providers, staff, and equipment to assist in the ongoing provision of care in situations where patient volume, acuity, or nature of illness or injury exceeds the capabilities of the CCTL and staff.
10d. We suggest utilizing a staging area for patients prepared and awaiting transport. This area should ideally be located near the point of embarkation and be staffed by medical personnel with training and experience in critical care evacuation. These personnel should be prepared to provide triage and perform ongoing medical care interventions prior to transport. The area should have the capability for additional surgical and medical stabilization pretransport if necessary.
Sending Critical Care Patient Information With Patient
11a. We suggest electronic transfer of patient information to the receiving hospital is optimal because a complete medical record can be included. Electronic transfer may be through an intranet or by copying patient information onto a USB flash memory drive or compact disk and transferring the information with the patient (see the “Business and Continuity of Operations” article in this consensus statement).
11b. We suggest a paper medical record be required to travel with the patient because there may be no ability to send an electronic copy of the medical record, or the receiving facility may not be able to read the electronic format of the medical record. A backup paper system may require (a) a printed copy of the electronic medical record or (b) a handwritten patient identification on a standardized patient tracking form. Any paper system should include basic patient identification, problem lists, and medications on forms that travel with the patient.
Transporting Critical Care Patients to Receiving Hospitals
12a. We suggest transportation methods should prioritize moving the greatest number of patients as rapidly and safely as possible to locations with adequate capacity and expertise where definitive care can be provided.
12b. We suggest local evacuation of highest acuity patients to hospitals with additional capacity by ground or rotary transport may be most appropriate to minimize risk and reduce ongoing critical care demands at the incident facility.
12c. We suggest alteration in the usual standards for modes of transport may be required during a disaster where transport resources are overwhelmed and evacuation and transport of critically ill patients to a receiving hospital ICU is required.
Tracking Critical Care Patients and Equipment
13a. We suggest tracking of patients should commence in the sending clinical unit, continue to the point of embarkation, and if possible, continue to the destination facility. Tracking of the patient and equipment should commence prior to being loaded onto the transportation. Minimum data sets for tracking should include the patient first and last name, date of birth, medical record number or tracking number or triage number, time leaving facility, transportation company name and transport vehicle number, and expected destination and next of kin.
13b. We suggest both the evacuating and receiving hospitals should track patients and equipment.
13c. We suggest tracking systems may be electronic or paper. In the event of complete power failure, however, a redundant paper system for tracking of patients and equipment should be performed by both sending and receiving hospitals, with communications provided to the sending hospital and/or a centralized coordinating center to confirm receipt of the patients.
13d. We suggest evacuation drills should test tracking of patients and equipment both by electronic and paper systems.
1. In the event of an incident with mass critical care casualties, we suggest all hospitals within a defined geographic/administrative region (eg, state), health authority, or health-care coalition should implement a uniform triage process and cooperate when critical care resources become scarce.
2. We suggest critical care only be rationed when resources have, or will shortly be, overwhelmed despite all efforts at augmentation and a regional-level authority that holds the legal authority and adequate situational awareness has declared an emergency and activated its mass critical care plan.
3. We suggest health-care systems provide oversight for any triage decisions made under their authority via activation of a mass critical care plan to ensure they comply with the prescribed process and include appropriate documentation.
4. We suggest health-care systems that have instituted a triage policy have a central process to update the triage protocol/system so that information that becomes available during an event informs the process in order to promote the most effective allocation of resources.
5. We suggest health-care systems establish in advance, a formal legal and systematic structure for triage in order to facilitate effective implementation of triage in the event of an overwhelming disaster.
6. We suggest health-care systems that have instituted a triage policy triage patients based on improved incremental survival rather than on a first-come, first-served basis when a substantial incremental survival difference favors the allocation of resources to another patient.
7a. We suggest health-care systems that have instituted a triage policy have clinicians with critical care triage training function as triage officers (tertiary triage) to provide optimum allocation of resources.
7b. We suggest triage officers should have situational awareness at both a regional level and institutional level.
7c. We suggest in trauma or burn disasters, triage be carried out by triage officers who are senior surgeons/physicians with experience in trauma, burns, or critical care and experience in care of the age-group of the patient being triaged.
7d. We suggest in environments where triage is not usual, individual triage officers or teams consisting of a senior intensive care physician and an acute care physician be designated to make mass critical care triage decisions in accordance with previously prepared, publicly vetted, and widely disseminated guidelines.
7e. We suggest in limited resource settings in which there is a limited need for expansion of critical care resources, a continuation of well-established systems is appropriate.
8. We suggest triage protocols (clinical decision support systems), rather than clinical judgment alone, be used in triage whenever possible.
9. We suggest in health-care systems that have instituted a triage policy, technology such as baseline ultrasound, oxygen saturation as measured by pulse oximetry, mobile phone/Internet, and telemedicine be leveraged in triage where appropriate and available to augment clinical assessment in an effort to improve incremental survival and efficiency of resource allocation.
10. We suggest triage decision processes, whenever possible, provide for an appeals mechanism in case of deviation from an approved process (which may be a prospective or retrospective review) or a clinician request for reevaluation in light of novel or updated clinical information (prospective).
11a. We suggest tertiary-care triage protocols for use during a disaster that overwhelms or threatens to overwhelm resources be developed with inclusion and exclusion criteria.
11b. We suggest the inclusion criteria for admission to intensive care.
11c. We suggest patients who will have such a low probability of survival that significant benefit is unlikely be excluded from ICUs when resources are overwhelmed.
11d. We suggest consideration be given to excluding patient groups that have a life expectancy < 1 year.
11e. We suggest if a physiologic (nondisease-specific) outcome prediction score can be demonstrated to reliably predict mortality in a specified population upon screening for ICU admission, it is reasonable to use this to exclude admission for patients with a predicted mortality rate > 90%. Similarly if a disease-specific score can be demonstrated to reliably predict mortality when used in the same manner for patients with the disease, we suggest it is reasonable to use this to exclude admissions for patients with a predicted mortality rate of > 90%.
11f. We suggest each patient’s condition be reassessed after a suitable time period (eg, 72 h) by the triage officer or triage team. If at that point the patient meets the criteria for exclusion from ICU, consideration should be given to withdrawal of therapy. If in the future a score is demonstrated to reliably predict high mortality when the patient is assessed during ICU stay, this should be used in preference to or as a supplement to clinical judgment.
Defining Special Populations for Mass Critical Care
1. We suggest the definition of special populations for mass critical care be those patients that may be at increased risk for morbidity and mortality outside a fully functional critical care environment or those patients that present unique challenges to providers when a full complement of supportive services is not available. We include the chronically ill and technologically dependent as the fragility of their baseline health puts them at significant risk for progression to a higher level of medical need.
Special Population Planning
2. We suggest critical care disaster planning include special populations.
3. We suggest professional societies, advocacy groups, governmental, and nongovernmental organizations be consulted when planning special population disaster preparedness and just-in-time care.
4. We suggest daily needs assessment of shelters include identification of those residents from special populations susceptible to decompensation to critical illness. A system to refer those identified to appropriate medical care should be in place.
5. We suggest disaster preparedness for special populations be part of their primary health-care maintenance. These patients should also be identified pre-event by their community (ie, nursing home facilities, health-care services, and social services providers) as an at-risk group for decompensation during a disaster and measures be taken to ensure they have a continuum of care during the event.
Planning for Access to Regionalized Services for Special Populations
6. We suggest identification of regionalized centers and establishment of communication be included in mass critical care planning.
7. We suggest regional specialized centers have mass disaster plans in place that include easily accessible, multidimensional, round-the-clock expertise available for consultation by local providers during mass critical care events.
8. Some special populations of mass critical care may require early transfer to specialized centers to maximize outcomes so should be identified early.
Triage and Resource Allocation of Special Populations
9. We suggest triage and resource allocation of special populations adhere to the same resource allocation strategy and process as the general population.
10a. We suggest local, regional, and national critical care pharmacists and resources be identified during disaster preparedness.
10b. We suggest access to critical care or specialist pharmacist and resources include consideration for special populations such as those with burns, cirrhosis, organ transplant, and need for dialysis.
10c. We suggest pharmacists, especially those with critical care and specialty training, be an integral part of any mass critical care disaster team.
Crisis Standards of Care for Special Populations
11. We suggest research be conducted in crisis standard of care triggers for special populations that includes clinical, planning, and ethical domains across the life cycle of a disaster.
12. We suggest experts in the care of technology- and resource-dependent special populations convene to discuss and determine the acceptable parameters for crisis standards of care for a disaster.
National Government Support of Health-care Coalitions/Regional Health Authorities—Policy
1a. We suggest political leadership at national levels should support health-care preparedness through financial assistance, support of market driven incentives, and preparedness requirements to health-care coalitions/regional health authorities (HC/RHAs).
1b. We suggest national governments should support the development of responsive and nimble disaster/pandemic research processes that can both organize and assess information from prior disasters/pandemics, acquire real-time data in an ongoing one to provide situational awareness, and which can also learn from and support international disaster relief efforts.
1c. We suggest national, state/province/regional, and city/district governments should:
• Working with health-care experts and leadership, develop formal legal disaster/pandemic activation mechanisms to initiate, implement, and support disaster/pandemic plans and standards of care for HC/RHAs and health-care professionals; and legally initiate step down termination procedures and processes as conditions and criteria warrant in the recovery phase
• Work with health-care experts and leadership in the greater health-care community to develop and refine specific “trigger” criteria for formal legal activation and step down termination procedures and processes of disaster/pandemic plans and standards of care.
1d. We suggest local governments and government agencies should be formal partners in their local health-care coalition(s), and be actively engaged with their ongoing preparedness and response activities.
Teamwork Within HC/RHAs—Foundational Principles
2. We suggest health-care coalition partners should work together, with the following objectives:
2a. HC/RHA clinical and administrative leaders from all partners meet together on a routine, scheduled basis. Clinician leaders must include critical care medicine experts.
2b. HC/RHA clinical and administrative leaders from all partners work together at least yearly with primary focus on developing and updating joint disaster/pandemic preparedness plans based on likely events (Hazard Vulnerability Analyses).
2c. HC/RHA clinical and administrative leaders from all partners jointly practice activation and implementation of disaster/pandemic plans and standards of care through exercises.
2d. HC/RHA partners activate their communication and collaboration mechanisms for virtually all actual or potential surge events, or unusual or large scale planned or unplanned events requiring cooperation, to ensure optimal responses and enable experience working together.
2e. HC/RHAs identify clinical experts to oversee and address the needs of specific populations, especially pediatrics, and also specialty populations such as trauma, burns, oncologic, etc.
2f. HC/RHA clinical and administrative leadership should be defined by position, not specific personnel, consistent with Incident Command System (ICS) nomenclature or equivalent, and designed with appropriate redundancy.
Systems-Level Communication—Foundational Principles
3a. We suggest HC/RHAs should have secure online and/or published directories for all partners’ clinical and administrative leadership, with emergency contact information (phone numbers, e-mail addresses, pagers, cell phone texting preferences, other means) and current call schedules.
3b. We suggest HC/RHA’s should have defined communication vehicles which may include (but are not limited to): dedicated secure health-care coalition web sites; conference call lines and teleconferencing technologies (eg, Skype, others); hospital phones (land lines and cell phones); pagers, hand held walkie-talkies, ham radios, or other similar means of communication; telemedicine technologies, such as E-ICU, integrated into their disaster plans.
3c. We suggest HC/RHA partners should attempt to routinely use those agreed upon communication vehicles when working together.
3d. We suggest all agreed upon communication vehicles should be tested on a scheduled basis, with objective criteria to validate the test.
3e. We suggest the choice of communication vehicles and testing may be based on likely disaster/pandemic events (Hazard Vulnerability Analyses), and/or other appropriate considerations.
3f. We suggest developing defined disaster/pandemic plans for monitoring and leveraging popular social media (eg, Twitter, Facebook, others) during all actual or potential surge events, or unusual or large scale planned or unplanned events requiring cooperation, as both a means for gathering and transmitting information, as appropriate.
3g. We suggest HC/RHAs should have defined communication tools designated for each level of organizational leadership, which should be consistent with ICS structure or equivalent.
System-Level Surge Capacity and Capability
4a. We suggest HC/RHA surge objectives should be consistent with individual hospital surge goals and include the capability to surge to:
• Up to 200% above routine maximal capacity based on the nature and severity of the disaster (contingency to crisis)
• Up to the limit of the total number of ventilators available to coalition partners.
• Up to projected patient loads in a slow onset, slow evolving disaster.
4b. We suggest HC/RHAs should be able to monitor and track their defined surge capacity supplies and equipment, ideally “real-time” and electronically, with the intent of being able to use all HC/RHA assets. These supplies and equipment may include identified caches of important medications or equipment, and bed availability among partners.
4c. We suggest HC/RHAs should have the ability to track the number of available ICU capable personnel (“force multipliers”) and other designated specialist “resources” (eg, pediatric and special populations) through their partner hospitals. Partners with telemedicine capability (such as tele-ICU’s) should have plans for how to use this resource to optimize the use of pediatric and specialty expertise across hospitals served by the telemedicine resource.
4d. We suggest HC/RHAs should have defined policies and procedures for emergency privileging for all health-care professionals designated as coalition resources.
4e. We suggest fair and adequate reimbursement for expenditures and loss of revenue related to delivery of acute critical care services during a disaster or pandemic must be ensured. This should include the guarantee of payments from governmental sources, as well as by insurance companies and other payers of health-care services.
Pediatric Patients and Specialty Populations
5a. We suggest HC/RHAs have identified, and be familiar with, the following pediatric disaster/pandemic designated resources including, but not limited to:
• Pediatric consultative specialists available by dedicated phone line support and/or dedicated video or telemedicine consultation.
• Designated pediatric surge personnel (eg, pediatric hospitalists, others) available to non-pediatric hospitals and health systems to support surge in contingency or crisis level events, with a defined plan for how to activate this resource when needed.
• Identified pediatric capable transport resources for allocation and matching of pediatric patients to available HC/RHA pediatric resources.
• Knowledge of available key supplies, medications, and other pediatric assets; location of these assets with a defined process for how they may be accessed urgently; and ability to monitor when asset reserves fall below a defined critical threshold.
• Pediatric educational resources. If web-based, they should be found on HC/RHA websites, or with links to appropriate resources. If published, resources should be readily available to all partners.
5b. We suggest HC/RHAs should have plans to provide care for specialty populations routinely found in their catchment area or region in parallel as described for pediatrics. Resources should include consultative services, potential surge personnel, transport resources, specialty supplies/medications, and educational resources. These populations include but are not limited to trauma, nephrology, burns, oncologic patients.
5c. Health-care coalitions, health systems, and hospitals identify patients with high-level chronic disease care needs, such as a home ventilator, home oxygen, chronic dialysis, and work to ensure their needs are met at home to help prevent these patients from having to seek assistance at hospitals.
6a. We suggest during a disaster requiring transfer of patients, whether from emergency medicine departments or inpatient areas, transferring partners may have initial choice of where patients are referred based on traditional referral patterns. However, HC/RHA leadership must oversee this process, and be able to intercede as both a resource and with the authority to redirect transfers based on anticipated or actual events. Defined health-care coalition coordination processes and transfer resources should be planned and identified ahead of time.
