Even modest numbers of critically ill patients with COVID-19 are rapidly exceeding existing hospital capacity. Although a minor or moderate surge can be accommodated by using conventional and contingency surge strategies such as conserving, substituting, adapting, and reusing existing resources, current experiences from other countries managing COVID-19 suggest that the magnitude of the surge will substantially exceed capacity, necessitating a crisis surge response.<xref rid="bib1" ref-type="bibr">1</xref>, <xref rid="bib2" ref-type="bibr">2</xref>, <xref rid="bib3" ref-type="bibr">3</xref>, <xref rid="bib4" ref-type="bibr">4</xref> The clinical demands will exceed the ability to provide one or more crucial resources essential to deliver basic critical care, therefore necessitating decisions regarding the reallocation of resources. This potential requires preparation of a triage system to best allocate available critical care resources to meet severe surge to maximize benefit for the greatest number of people.<xref rid="bib4" ref-type="bibr"><sup>4</sup></xref><sup>,</sup><xref rid="bib5" ref-type="bibr"><sup>5</sup></xref> Importantly, this triage system should only be deployed as a last resort and implemented as resources become limited and after all attempts to surge, move patients, or shift resources from regions with greater availability have been made.</p><p id="p0015">When implemented, triage must be applied to all current and new patients presenting with critical illness, regardless of the diagnosis of COVID-19 or another illness, while maintaining underlying ethical principles of social justice, beneficence, nonmaleficence, respect for people and their dignity, veracity and the need to uphold trust within society, and fidelity to one another within health systems. We must uphold our duty to care for all patients, even those unable to receive critical care interventions. To enact this triage plan, a triage decision support protocol, infrastructure, processes, legal and regulatory protections, and training<xref rid="bib5" ref-type="bibr"><sup>5</sup></xref> are required, all of which are currently lacking in most institutions and regions.</p><p id="p0020">Additionally, there is a need to ensure that patients who do not initially receive critical care resources are still provided the best supportive care possible and are reevaluated, at minimum daily, for consideration of resource allocation as supplies become available. This will result in a sliding scale from crisis to contingency, and flexibility should be anticipated. The absence of a triage system, consistently applied within and between hospitals, may lead to unnecessary deaths, increased moral distress for frontline physicians, and a lack of public confidence in the fairness of scarce resource allocation. It is important to recognize that the initiation of adult triage levels does not itself imply initiation of pediatric triage (or vice versa). However, dependent on the level of impact within the pediatric system, pediatric hospitals will need to consider lower-level triage initiation at a point when adult systems have reached crisis triage, to respect the principles of utility and fairness population-wide.</p><p id="p0025">With appropriate critical care surge planning, we hope that the use of a triage plan that limits the delivery of critical care should be rare, but the potential consequences of failing to prepare for this eventuality are serious.</p><p id="p0030"><xref rid="tbl1" ref-type="table">Table 1</xref>provides operational steps to implement a triage system within a state, county, or jurisdiction and highlights respective stakeholder responsibilities.<table-wrap position="float" id="tbl1"><label>Table 1</label><caption><p>Operational Steps to Implement a Triage System</p></caption><table frame="hsides" rules="groups"><thead><tr><th>Specific Actions Suggested</th><th>Stakeholders Responsible</th></tr></thead><tbody><tr><td>1.

Early experience with the virus in China and Italy suggests that the virus has a community symptomatic attack rate of COVID-19 of up to 30% (with approximately double that number of SARS-CoV-2 infections because up to one-half of cases appear to be asymptomatic or paucisymptomatic). Of these, as many as 5% to 25% may require hospital admission, 5% to 8% may require ICU admission, and 2% to 4% may require mechanical ventilation for acute respiratory failure. For example, in the greater New York City metropolitan area alone (with a population of 8.4 million people), a community attack rate of 35% (ie, a symptomatic attack rate of 17.5%), leading to 1.3 million people with varying levels of disease from now until midsummer, could generate approximately 88,000 total hospitalizations and 13,000 ICU admissions under a scenario in which 7% of all affected people require hospitalization and 14% of those require critical care beds. Under a more severe scenario (20% hospitalized and 24% to ICU, rates now seen during the week of March 23, 2020, at New York City hospitals), this could lead to up to 190,000 hospitalizations and 58,000 ICU admissions over the course of the pandemic, with a peak concurrent ICU census of approximately 22,000 before summer. At baseline, the United States has approximately 68,000 adult and 5,000 PICU beds, a per capita ICU bed availability that exceeds most other countries.<xref rid="bib6" ref-type="bibr"><sup>6</sup></xref> Clearly, either scenario is likely to vastly overwhelm any current health system, as is occurring in Italy and elsewhere.</p><p id="p0040">Triage is the course of action that we take when we have exhausted our ability to expand our critical care resources, that is, to surge. Surge capacity refers to the ability of a hospital or other health-care system to expand its normal operating capacity in the setting of an emergency. Surge capacity includes the key features of staff, space, supplies, and systems with communications as a critical fifth feature. All five of these elements are necessary to permit hospitals to surge effectively in disasters. The Task Force for Mass Critical Care<xref rid="bib3" ref-type="bibr"><sup>3</sup></xref> provided a classification system for differing levels of surge response in their 2014 guidelines on the management of the critically ill during disasters and pandemics.</p><sec id="sec2.1.1"><title>Conventional Capacity</title><p id="p0045">A hospital should be able to increase its critical care capacity by approximately 20% above its normal limitations. This level would be implemented in major mass casualty incidents that trigger activation of the hospital emergency operations plan. Most facilities should be able to achieve this level of response using existing staffing and resources, including strategies such as cancellation of elective procedures and transferring of appropriate patients out of ICUs.</p></sec><sec id="sec2.1.2"><title>Contingency Capacity</title><p id="p0050">This level would be used during a disaster whose medical demands significantly exceeded routine hospital and community resources. At this level, a hospital will expand its critical care capacity by up to 100%, in part through modification of existing spaces and expanding the use of certain staff members. For example, critical care services may be provided in a postanesthesia care unit, stepdown unit, or other high-dependency area with cross-training of staff under the direction of critical care team members. Ventilators intended for the operating room, noninvasive ventilation, or transport can be repurposed to augment the overall ventilator supply. At this level of surge response, it can be expected that medical care will be at or near the predisaster prevailing community standard.</p></sec><sec id="sec2.1.3"><title>Crisis Capacity</title><p id="p0055">This level would be implemented in catastrophic situations, such as suggested by the current COVID-19 modeling, that result in a significant impact on the standard of medical care that can be provided. Severe limitations of space, staff, and supplies would not allow hospitals to provide the usual standard of medical care. At this level, hospitals and communities will need to consider triage principles.</p><p id="p0060">The numbers provided are a construct, not absolute rules. As the balance of resources vs demand shifts over time during an emergency, the degree of the surge response and any necessary triage will shift as well (<xref rid="fig1" ref-type="fig">Fig 1</xref>). Shortages of trained staff, ventilators, or personal protective equipment (PPE) are very real threats in the current pandemic and will likely be triggers for shifting to triage and crisis standards of care if they should occur. As such, we need to have an accurate inventory of those resources, understanding that the limitations would likely be staff rather than ventilators or space; however, the ongoing experiences in New York suggest that all three may easily be in short supply. However, the early experience in Italy, which has roughly the same number of ICU beds and ventilators per capita as many other developed countries, indicates that our current critical care resources are insufficient to manage a similar outbreak.<fig id="fig1"><label>Figure 1</label><caption><p>Impact of triage in crisis surge response to balance demand and capacity, demonstrating different levels of triage depending on the degree of demand in relation to system capacity.</p></caption><graphic xlink:href="gr1_lrg"></graphic></fig></p></sec></sec><sec id="sec2.2"><title>A Triage Plan Is Necessary to Ensure the Greatest Benefit to the Greatest Number, and to Reduce the Number of Patients Who Will Be Unable to Receive Critical Care Resources</title><p id="p0065">A number of pandemic triage plans have already been proposed for viral respiratory illness and are outlined in a recent overview on triage.<xref rid="bib7" ref-type="bibr"><sup>7</sup></xref> When the demand for critical care overwhelms the resources available, a resource allocation plan is essential to deliver both the greatest benefit to the greatest number of people, and to maintain the function of the health-care system and prevent random or otherwise inequitable distribution of scarce resources.</p><p id="p0070">Triage require us to accept that some individuals will not receive critical care resources which might have been dedicated to their care under normal circumstances, whereas some individuals will have critical care interventions withdrawn if they fail to improve. Although as yet untested in practice, modeling studies evaluating predicted mortality in pandemics have demonstrated that more people will die because of lack of critical care resources than would have died if triage systems were implemented.<xref rid="bib8" ref-type="bibr"><sup>8</sup></xref><sup>,</sup><xref rid="bib9" ref-type="bibr"><sup>9</sup></xref> Without a triage plan, patients will receive critical care resources by random chance or a first-come, first-serve basis, likely leading to overall worse outcomes across a population and more individuals being denied critical care.</p><p id="p0075">A triage system requires an ethical basis, which we summarize in <xref rid="fig2" ref-type="fig">Figure 2</xref>.<xref rid="bib10" ref-type="bibr"><sup>10</sup></xref> Limiting and withdrawing critical care resources are justified by the utilitarian principle of providing the greatest good to the greatest number of people. Although the general principle of saving the most lives possible holds true in any system, the decisions of identifying which patients to prioritize for access to critical care will be difficult. A first-come, first-served model of triage has the advantage of simplicity but will exclude patients who lack transportation or easy access to care. A system based on age alone, with mechanical ventilation denied to patients over a given age cutoff, does not account for differences in baseline mortality risk because of underlying health.<fig id="fig2"><label>Figure 2</label><caption><p>Ethical principles involved in triage systems.</p></caption><graphic xlink:href="gr2_lrg"></graphic><attrib>(Adapted with permission from the University of Toronto Joint Centre for Bioethics Pandemic Influenza Working Group.<xref rid="bib10" ref-type="bibr"><sup>10</sup></xref>)</attrib></fig></p><p id="p0080">Communities may choose to prioritize to key groups, to include health-care workers (HCWs), first responders, research volunteers, or others who are either perceived as risking their own safety for the public’s benefit or who have a special role in pandemic response; however, strict definitions of who is included in these key groups and the social utility of such preferences remain unresolved. Children and pregnant women may receive special priority in other schema, with the concept of saving not only the most lives but also the greatest number of years of life.<xref rid="bib11" ref-type="bibr"><sup>11</sup></xref><sup>,</sup><xref rid="bib12" ref-type="bibr"><sup>12</sup></xref> All of these must be taken in consideration, and different cultural priorities will vary between (and within) different countries. This paper is inadequate to answer these questions for a given community; sample triage protocols are available on the CHEST website for review and guidance.</p><p id="p0085">These decisions to implement a triage system should be driven by the inability of regional health systems to deliver care to all critically ill patients because of an overwhelming surge in demand that reaches crisis levels. The triage protocol we are referring to in this case is for tertiary triage, which takes place at an acute care hospital when deciding whether or not to admit for critical care services.<xref rid="bib5" ref-type="bibr"><sup>5</sup></xref> In a broad sense, patients who present for tertiary triage are going to fit into one of three categories: (1) too well to benefit from critical care, (2) too sick to benefit from critical care because of severe underlying illness or a poor likelihood of surviving their hospitalization, or (3) sick enough to benefit from critical care. The goal of triage protocols is not to exclude categories of patients based on age or underlying disease, and protocols that explicitly exclude patients based on a single criterion alone may run afoul of antidiscrimination laws in many jurisdictions. Rather, the goal of a triage protocol is to maximize the use of critical care resources for patients in the third category. These categories apply to all patients presenting with critical illness under crisis standards of care, not just those infected with SARS-CoV-2.<xref rid="bib13" ref-type="bibr"><sup>13</sup></xref> Although we must recognize that patients less likely to benefit from critical care may not be provided those services and interventions under a triage system, reallocation may occur as resources and demand change.</p><p id="p0090">The best available epidemiologic data, combined with expert input, will be required to create triage protocols that reflect COVID-19-specific mortality and resource utilization predictions. Although the use of acute illness scores, such as the Sequential Organ Failure Assessment (SOFA) score, were proposed for previous pandemic triage plans, a growing body of evidence suggests such scoring systems are unlikely to predict critical care outcomes with sufficient accuracy,<xref rid="bib14" ref-type="bibr"><sup>14</sup></xref><sup>,</sup><xref rid="bib15" ref-type="bibr"><sup>15</sup></xref> in particular patients suffering from COVID-19,<xref rid="bib16" ref-type="bibr">16</xref>, <xref rid="bib17" ref-type="bibr">17</xref>, <xref rid="bib18" ref-type="bibr">18</xref>, <xref rid="bib19" ref-type="bibr">19</xref> or be a useful basis for triage decisions based on the current protocol cut points.<xref rid="bib13" ref-type="bibr"><sup>13</sup></xref><sup>,</sup><xref rid="bib20" ref-type="bibr"><sup>20</sup></xref><sup>,</sup><xref rid="bib21" ref-type="bibr"><sup>21</sup></xref></p><p id="p0095">The prognostic accuracy of SOFA varies across its range of scores, with greater variability and less accuracy at lower scores than at higher scores, and is not immediately applicable to all disease states: a patient with sepsis may have a SOFA score of 4 and a low mortality risk, for example, whereas a patient with an intracranial hemorrhage and a Glasgow Coma Scale score of 3 could share this SOFA score of 4 but have a very high risk of death. Potentially subjective elements, such as the dose of vasopressor administered or the assessment of Glasgow Coma Scale during sedation breaks, are subject to physician judgment and are affected by drugs and other interventions.<xref rid="bib22" ref-type="bibr"><sup>22</sup></xref> Because outcomes at differing SOFA scores vary across studies and are generally absent in the context of crisis standards of care, system-level data are necessary to guide selection of threshold values.</p><p id="p0100">All of these factors combine to raise a number of logistical and ethical concerns regarding the use of the SOFA score in a triage algorithm. Therefore, we propose triage protocols that are not solely dependent on SOFA (or another single scoring tool) because SOFA is unlikely to be adequate in and of itself for triage decisions. It is important to mention that any scoring system at this stage of the pandemic will need to be pragmatic and combine other predictors of ICU mortality, such as disease-specific indicators for non-COVID-19 conditions, frailty scores, comorbidity indices, and physician judgment as best possible. This will need to be balanced against the need for a triage scoring tool that is actionable: complex enough to provide prognostic information with acceptable accuracy, but simple enough to be implemented in a timely manner.</p><p id="p0105">As our knowledge of COVID-19 increases, it is likely that better prognostic scoring tools will be developed; when this occurs, triage systems should incorporate these into their protocols to improve our prediction of critical care outcomes and mitigate the limitations of physiological indices in isolation.</p><p id="p0110">Periodic reassessment of patients is a necessary part of any triage algorithm, to assess for clinical improvement, deterioration, or any other changes that affect prognosis. COVID-19 illness seems to last longer than influenza, suggesting that reassessments at 48 and 120 h noted in earlier triage protocols<xref rid="bib5" ref-type="bibr"><sup>5</sup></xref><sup>,</sup><xref rid="bib13" ref-type="bibr"><sup>13</sup></xref> are too short to provide an adequate trial of therapy in patients with COVID-19. Therefore, any triage protocol will need to be reassessed and modified as clinical experience with SARS-CoV-2 infection grows.</p></sec><sec id="sec2.3"><title>Effective and Ethical Triage Requires Infrastructure, Oversight, Processes, and Training</title><p id="p0115">Triage criteria are one component of a three-part system designed to integrate clinical decisions with incident commanders at the facility and jurisdictional level.

Strong, collaborative regional efforts are a cornerstone of effective response and must be implemented regardless of any competitive posture between health-care systems that may exist during usual operations. Hospitals must share information, adjust protocols, and balance resources and patient loads across the immediate surrounding region to ensure as consistent a standard of care as is possible. The regional structures should involve sharing information about available beds, ventilators, advanced care resources such as ECMO (a regional approach to ECMO allocation is found in the card set previously referenced), and staff, and a critical care working group to establish joint triage protocols and coordinate mass critical care planning, and potentially involve a central gatekeeping mechanism for regional referrals and critical care triage. A central triage committee should be appointed, with connections to local triage officers and teams at each hospital. A standardized documentation process (paper or electronic) should be used to allow efficient data collection and decision-making. The protocol should be made available to all triage personnel in advance to allow familiarization and feedback. A mechanism to revisit triage decisions that vary from conventional care practices should be strongly considered to reassess individual patient progress if clinical demand decreases or if capacity increases. <xref rid="fig6" ref-type="fig">Figure 6</xref>illustrates the structure of a triage system at the regional level and integration with a hospital incident command structure.<fig id="fig6"><label>Figure 6</label><caption><p>Triage infrastructure.</p></caption><graphic xlink:href="gr6_lrg"></graphic><attrib>(Reprinted with permission from Christian et al.<xref rid="bib5" ref-type="bibr"><sup>5</sup></xref>)</attrib></fig></p></sec></sec><sec id="sec2.5"><title>Many Current Legal and Regulatory Frameworks Preclude a Triage System Because of the Need to Withhold or Withdraw Artificial Life Support Without Consent</title><p id="p0170">Legislation in most states and provinces provides the framework for medical decision-making. Broadly speaking, these laws indicate that plans of treatment require consent of the patient or their surrogate. In some jurisdictions, courts have ruled that physicians do not require consent to withhold CPR (or other life-sustaining measures) that they thought to be outside the standard of care.<xref rid="bib23" ref-type="bibr"><sup>23</sup></xref> Even within a single country, there may be wide regional variation on the degree to which physicians may make unilateral decisions regarding the provision of resuscitative care.<xref rid="bib24" ref-type="bibr"><sup>24</sup></xref></p><p id="p0175">A published report from the Institute of Medicine<xref rid="bib25" ref-type="bibr"><sup>25</sup></xref> outlined some of the important considerations for medical and legal standards of care in a disaster. Key elements of this report include that (1) medical and legal standards of care are not always the same, (2) standards are flexible according to the context of the situation, and (3) authorities need to provide clarity and guidance about standards. Physicians who face uncertainty about how courts and regulatory agencies will assess the standard of care “may react negatively to actual or perceived risks of liability,”<xref rid="bib25" ref-type="bibr"><sup>25</sup></xref> which would result in worse outcomes for all patients, families, and providers alike whether infected with COVID-19 or not.</p><p id="p0180">To implement a triage system, many jurisdictions would need a modification or suspension of their health-care consent acts to the effect that in the situation of pandemic triage, consent would not be required for decisions about the withholding or withdrawal of artificial life support. In addition, medical licensing bodies should modify their policies to indicate that the standard of care in a pandemic is to triage patients according to an accepted plan, and that consent is not required for treatment decisions taken according to that plan.</p><p id="p0185">Although standards of care may change during a pandemic, crisis standards of care still represent standards; indeed, the need for oversight and review may be even more pressing in this context. If time and circumstances allow, a mechanism for appeal may be built into the system. Such an appeal system must be rapidly accessible and able to decide in a timely enough manner to provide actionable direction to physicians. All triage decisions should eventually be reviewed to allow for transparency and accountability.</p></sec><sec id="sec2.6"><title>Standards of Care</title><p id="p0190">Withholding critical care resources must not mean neglect, and it should not be considered tantamount to terminal care or medical assistance during the dying process. We must care for all patients.</p><p id="p0195">Patients who do not receive critical care because of a triage system must be supported, and the rationale for medical decision-making must be clearly communicated to them or their family members. Shifting the normal role that patients and their surrogates play in decision-making is a substantial deviation from normal medical practice, carrying with it a commensurately large obligation to ensure that these individuals will receive the best possible care given the crisis response.</p><p id="p0200">Studies of severe acute respiratory illness have suggested that many patients with respiratory failure can recover effectively without mechanical assistance, and opioids can be used to treat dyspnea without increasing mortality.<xref rid="bib26" ref-type="bibr"><sup>26</sup></xref> A patient unable to receive invasive mechanical ventilation may be able to receive supplemental oxygen through a noninvasive route as resources permit.

It may be possible, depending on the capabilities of a given institution, to provide some forms of critical care monitoring and therapy in a crisis situation outside of the traditional ICU. Protocols to support the use of opioids for dyspnea, other key supportive and palliative interventions, and the conscientious use of therapies subject to shortages (eg, bronchodilators, antimicrobial agents, fluid therapy) can be of service for bedside physicians. Similarly, clear and standardized communication tools, such as information sheets, can inform the public about crisis standards of care, can inform about triage criteria, and may offer the wider community opportunities for feedback as a means of increasing public trust.</p></sec><sec id="sec2.7"><title>Family and Societal Support</title><p id="p0210">An effective triage system must help physicians maintain transparency in their decision-making. The transition of health-care systems to crisis care delivery requires a systematic communication strategy at the community level to explain the situation and ongoing efforts to maintain the best possible level of care. Patients and families have the right to expect that those with similar critical care needs will be treated fairly and equitably, with no preference to any particular group. A hotline and electronic communication platform may help gauge community response and concerns during the event and will inform leaders regarding the emotional reassurances needed by members of the society.<xref rid="bib30" ref-type="bibr"><sup>30</sup></xref></p><p id="p0215">Many centers have limited the number of caregivers at the bedside, reduced family movement in the hospital, and required the use of PPE for all visitors to the bedside. This use of PPE by visitors and caregivers will become increasingly problematic considering worldwide shortages, with some centers reportedly only permitting their use by visitors at crucial contact times, such as the end of life. These limitations in family contact can only increase the burden of suffering, and new methods will be needed to reduce this burden, to include the use of technologic solutions (eg, video conferencing via tablets and smartphones) to attempt to preserve as much intrapersonal contact as possible.<xref rid="bib31" ref-type="bibr"><sup>31</sup></xref></p><p id="p0220">With the use of triage algorithms in crisis care, even the most transparent systems of decision- making may lead to prolonged feelings of guilt from lack of personal preparedness, an inability to assist, or frustration toward the government and the medical system. Ancillary team members (including palliative care, psychiatrists, psychologists, other mental health workers, and social workers) will need to assist with the burden of communication with ICU families. These professionals should remain in regular communication with family via telephone, text message, or other means as best possible. It is additionally important to anticipate and plan for supporting these professionals, who themselves will require support because of secondary moral distress.</p></sec><sec id="sec2.8"><title>HCW Support</title><p id="p0225">The term moral injury has been increasingly suggested to describe the distress that HCWs can experience from the excessive demands of energy, strength, and resources often experienced within current health-care systems.<xref rid="bib32" ref-type="bibr"><sup>32</sup></xref> The resulting constellation of symptoms—fatigue, frustration, cynicism, and inefficiency—has historically been defined as burnout, but this term fails to capture the similarities that this syndrome may share with posttraumatic stress disorder or the severity of the associated psychological injury.<xref rid="bib33" ref-type="bibr"><sup>33</sup></xref></p><p id="p0230">Beyond the issues of fatigue and burnout, however, there are the very real threats of infection and personal harm because of workplace exposure to COVID-19. Shortages of PPE in the United States and other countries have exacerbated this threat; reports of hospitals curtailing PPE use and sanctioning HCWs for using their own personal PPE in the presence of shortages have only made these issues more acute.</p><p id="p0235">The principles of beneficence and nonmaleficence are core to the practices of medicine and nursing, and the impact of asking physicians to shift their perspective during a crisis surge response should not be underestimated.<xref rid="bib6" ref-type="bibr"><sup>6</sup></xref> Feelings of social isolation are common in times of crisis and are further exacerbated by current recommendations for social distancing, infection control practices, and prolonged use of PPE. Disruptions in normal routines, concern for personal welfare, and fear for the safety of loved ones all add additional stress. A significant number of physicians in active practice already exhibit signs and symptoms of moral injury, with higher self-reported rates of poor patient safety habits, more medical errors in their practice, and increased rates of suicidal ideation.<xref rid="bib34" ref-type="bibr"><sup>34</sup></xref> The personal risk to bedside physicians during the COVID-19 pandemic, especially in light of international shortages of PPE, only increases this strain on the workforce. This can be a significant threat to both the quality and efficiency of care in a crisis.</p><p id="p0240">Providing members of the health-care team with structured opportunities to debrief after critical events and ongoing opportunities for engagement and input to improve the inevitably dynamic work environment have also been shown to be effective to promote community, connectedness, and meaning. Incorporating these principles thoughtfully during triage system activation requires a systematic leadership communication plan to explain the reasons for its use; formal training to ensure consistent implementation; and collaborative, team-based approaches to decision-making led by the designated triage officers and including physicians directly caring for patients with the strong support of hospital ethics and palliative care experts.</p><p id="p0245">Similarly, institutions and governments must prevent the sanctioning of HCWs for attempting to protect their own (and their families’) safety through nonstandard PPE usage; instead, health-care organizations need to redouble efforts to expand PPE availability, be it through innovative reusage methods, adoption of acceptable alternative forms of PPE (eg, the use of industrial respirators), and governmental and industry support for increased manufacturing.</p><p id="p0250">Existing resilience measures and support programs will need to be strengthened to protect the psychological well-being of patients, families, and the HCWs treating them both during and after these events.<xref rid="bib5" ref-type="bibr"><sup>5</sup></xref> It is wise to consider a structured schedule of opportunities within each work unit and the hospital at large to encourage staff to learn about and use these measures, especially in the setting of anticipated prolonged periods of modified work practices that the current COVID-19 pandemic threatens to create.</p><p id="p0255">Institutions may refer to existing resources in implementing plans, such as the National Academy of Medicine in the United States (<ext-link ext-link-type="uri" xlink:href="https://nam/edu/clinicianwellbeing" id="intref0015">https://nam/edu/clinicianwellbeing</ext-link>) and the Intensive Care Society in the United Kingdom (<ext-link ext-link-type="uri" xlink:href="http://www.ics.ac.uk" id="intref0020">www.ics.ac.uk</ext-link>), which has put a free Wellbeing Resource Library online with specific content relevant to COVID-19.</p><p id="p0260">A personal connection with the patients is perhaps the most important and powerful tool to maintain our sense of purpose and best care for their ongoing needs, and structured opportunities to develop and maintain a human connection with the individuals whose needs we serve will also help to combat feelings of depersonalization in the critical care environment that are only exacerbated by the current crisis.<xref rid="bib35" ref-type="bibr"><sup>35</sup></xref></p></sec><sec id="sec2.9"><title>Pediatric Considerations</title><p id="p0265">Any triage system must balance the need to save the most lives possible with the need to save total life-years. Critically ill children therefore are usually considered separately from adults when triage considerations are made. The fundamental precepts of crisis critical care—including care and attention to the health of the entire family as a unit and respect for the role of parents—remain critical to the success of disaster management. Institutions must balance the needs of family-centered care vs the risk of disease transmission. One or more caregivers usually accompany pediatric patients; these caregivers are likely to be close contact with a patient and should be treated as presumably exposed; however, they may be asymptomatic at the time, and will require monitoring for symptomatic disease and potential quarantine.</p><p id="p0270">Incorporating children into a regional triage algorithm is complicated for a disease process such as COVID-19 that largely affects adults, at least in terms of critical illness. Much of pediatric critical care is separated into very few pediatric centers, with only some pediatric resources being applicable to adult groups. To prevent any hospital from needing to use crisis standards of care, pediatric-only hospitals in an affected region have a duty to surge to prevent adult and mixed adult/pediatric hospitals going into crisis as regional capacity needs require. In such a scenario, pediatric-only hospitals should consider the steps outlined in <xref rid="tbl1" ref-type="table">Table 1</xref>.</p><p id="p0275">Pediatric care should preferably be concentrated in pediatric centers to preserve necessary pediatric systems. Given the low mortality of most conditions with which children are admitted to intensive care (< 5%), patients < 18 years of age who meet the mortality criteria associated with the adult triage levels will be very rare, such that the adoption of the same triage system in pediatrics is unlikely to mobilize further resources. An entirely different algorithm that is pediatric-specific would be necessary in considering pediatric-specific triage policies. Some centers have modeled situations where a certain mortality rate or predicted ventilator-days could preclude the offering of invasive ventilator support to some children at a time of significantly increased short-term ventilator needs,<xref rid="bib8" ref-type="bibr"><sup>8</sup></xref> but there is a paucity of pediatric-specific data to guide such triage. Medical specifics aside, the guiding ethical principles remain the same for pediatric triage and should still be applied.</p><p id="p0280">Pediatric centers should regionally activate pediatric triage when shared pediatric resources (accounting for transportation capacity) are exhausted, with mortality predictions subject to expert opinion, which should be agreed on and documented by at least two members of the treating team. Prior to movement to higher triage levels, especially considering such steps being unlikely to mobilize resources, discussions should be held regarding movement of ventilators to pediatric centers from adult sites if there is a difference in resource demand.</p></sec></sec><sec id="sec3"><title>Conclusions</title><p id="p0285">This framework can provide the essential tools to rapidly assist communities to establish the infrastructure necessary to equitably meet the clinical needs of the greatest number of patients with COVID-19 during a time of scarce resources.
