Abstract
Palliative care is expanding its role into the surgical intensive care units (SICU). Embedding palliative philosophies of care into SICUs has considerable potential to improve the quality of care, especially in complex patient care scenarios. This article will explore palliative care, identifying patients/families who benefit from palliative care services, how palliative care complements SICU care, and opportunities to integrate palliative care into the SICU. Palliative care enhances the SICU team’s ability to recognize pain and distress; establish the patient’s wishes, beliefs, and values and their impact on decision making; develop flexible communication strategies; conduct family meetings and establish goals of care; provide family support during the dying process; help resolve team conflicts; and establish reasonable goals for life support and resuscitation. Educational opportunities to improve end-of-life management skills are outlined. It is necessary to appreciate how traditional palliative and surgical cultures may influence the integration of palliative care into the SICU. Palliative care can provide a significant, “value added” contribution to the care of seriously ill SICU patients.

Background/Introduction
Palliative care is an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual.
1
Palliative care is a rapidly growing subspecialty involving expert assessment and treatment of the physical, psychological, social, and spiritual needs of patients and families with serious illnesses. 2 To date, palliative care has not predictably played a distinct or complementary role in caring for postoperative patients in a surgical intensive care unit (SICU). During the past 2 decades, the prediction of survival of ICU patients has been a subject of intensive research, and tools such as the Sequential Organ Failure Assessment (SOFA), the Acute Physiology and Chronic Health Evaluation (APACHE II/III), and the Simplified Physiology Score (SAPS II) model have been developed for this purpose. Despite the validation of these prospective scoring systems, determining with certainty which specific patients will live or die in the SICU remains challenging.3,4 Patients of advanced age and with significant comorbidities are increasingly undergoing major surgery and are being cared for in SICUs. As intraoperative anesthetic and surgical care improves, critical care physicians frequently encounter patients who have had technically successful surgery but whose multiple comorbidities greatly diminish their physiological reserve and render them less resilient to withstand postoperative complications.
Palliative care was initially developed as a specialty to care for end-stage cancer patients. 2 The traditional and more modern conceptual models of palliative care are illustrated in Figure 1. The traditional model of pitting palliative care as an alternative to curative care only once the latter has failed is not applicable to advanced current surgical practice. Alternatively, a multifaceted palliative care paradigm that is integrated at a much earlier stage into disease-directed treatments is evolving. 2 This new model of palliative care does not depend on prognostic certainty nor on a precise time to request palliative care consultation. Instead, referrals to palliative care reflect the unmet needs of the patient, their families, and the services caring for them after operative treatment of patients with multiple comorbidities and limited physiological reserve. This article will discuss how to identify patients who will benefit from palliative care participation and will highlight how the integration of palliative care models into the SICU can enhance the quality of care for postoperative patients with complex, multifaceted care issues.

Conceptual models depicting palliative care components and their relationship to cure-directed care: The top model (traditional) pits palliative care as an alternative to curative care once the latter has failed; the bottom model (new) conceptualizes palliative care as a multifaceted palliative care paradigm involving such services early and in various critical forms, both alongside disease-directed treatments.a
Identifying Patients/Families Who Will Benefit From Palliative Care Services
A practice model that permits the overlay of acute care and palliative care, as depicted in Figure 1, will best serve SICU patients with serious acute or chronic organ failure. A concise summary of when to consider a palliative care consult for ICU patients is as follows: pain and symptom management in complex patient care scenarios, the need to explore non-ICU care options, the occurrence of staff questioning the appropriateness of acute care support, difficult family dynamics or differing opinions regarding prognosis influencing decision making, and support for patients who are frequently readmitted to the ICU. 5 Patient referrals to the palliative care service can be determined on an individual patient basis or they may be identified through a set of “triggers” that will create an automatic referral at any time during their ICU stay. 6
The American College of Surgeons Surgical Palliative Care Task force highlighted the following “triggers” for a palliative care consult from a surgical perspective: family request, family disagreement with the team, decreased level of consciousness for over a week, futility, expected death in the SICU, SICU stay longer than 1 month, more than 3 admissions to the SICU during a single hospital admission, life expectancy less than 6 months, unresectable malignancy, advance directive authorizing withdrawal of life support, and multisystem organ failure. 7 In addition, we recommend that palliative care consultation be considered when the patient’s physical symptoms do not respond to ICU symptom management, or if the patient/surrogate or staff have questions regarding health care options other than the ICU, such as palliative hospice care.2 Under such circumstances, palliative care consultations may influence both the patient’s goals and plans of care. 8
Why Consult Palliative Care Services When the Palliative Principles of Care Are Inherent in SICU Care?
Palliative care principles include providing chronic pain and symptom management for those with life-threatening or life-limiting illness, acknowledging the concerns and expressed wishes of patients and families, and addressing psychological, social, and spiritual needs. This should be complemented with providing continuity of care and recognizing futile treatments. 9 These principles can assist surgeons in managing chronically ill patients, some who may have unrealistic expectations. 10
Many patients benefit from palliative care services that require lengthy amounts of time to sort through and that complement procedure-based modular surgical care. Patients, surrogates, and their health care teams have issues that are complex and require numerous discussions to optimize continuity of care and coordination of care during daytime hours. These demands may coincide with operating and surgical clinic hours, thus making it difficult for surgeons to consistently participate. Palliative care teams can collaborate with surgeons and intensivists to assess and manage symptom distress and prognosis; to review health care delivery options such as continued high-intensity ICU care, chronic complex care, and palliative hospice care; to optimize continuity of care; and to assist patients, families, and ICU staff in reframing the goals of care. 5
Models of Palliative Care for Integration Into SICU Care
A spectrum from integrative to consultant models of palliative care has been proposed to integrate palliative care into the ICU. 11 The integrative model of palliative care focuses on educating ICU staff of the principles and practices of palliative care. These principles then become embedded into the ICU staff’s practices, and a palliative care consult service is not required. However, this model requires sustainable maintenance of palliative care competence for ICU providers, which is dependent on the commitment of the ICU administration, resources, staff, and culture. 11
Palliative care consultant models directly bring palliative care services into the ICU. The ICU team refers the patients, and the components of care shared between these services include chronic pain and symptom management, assistance with decision-making conversations and family support, and, if indicated, transfer to a chronic respiratory support unit, palliative care unit, or hospice. The palliative care team should be supported by ICU nursing, physician, psychology, social work, ethicist, and spiritual care practitioners to achieve the above-noted common goals. 11
Components of Palliative Care Consultation to Enhance SICU Care
The components of a palliative care service in the ICU include enhanced communication strategies 12 when the prognosis is grave or uncertain, decision making from the patient/substitute decision maker (SDM) and team perspectives,12,13 and the reduction of physical, emotional, and social concerns.12 -14
Recognize Pain and Distress
It takes an abundance of time and high level communication skills to carefully identify, assess, and manage the symptoms of complex ICU patients with acute and chronic organ failure. Ventilated patients in the SICU have difficulty expressing their symptoms given their loss of voice, in concert with preexisting cognitive changes and ongoing sedation. In particular, pain, dyspnea, anxiety, restlessness, agitation, delirium, sleep disturbances, thirst/dry mouth, generalized weakness, and a sense of abandonment occur frequently in this patient group.15 -21 Recently, clinical practice guidelines were published for the management of adult ICU patients with pain, agitation, or delirium. 22 A palliative care team can focus on these symptoms, with the goal of improving the lived experience of the patient, with additional beneficial effects for the family and providers. A palliative care philosophy can strengthen patient symptom management in the SICU, regardless of the patient’s ultimate prognosis.
Establish Patient’s Wishes, Beliefs, and Values and Their Impact on Decision Making
Understanding patient preferences is a cornerstone in providing patient-centered care. These preferences are a blend of the patient’s expressed wishes, beliefs, and values. 23 It is important that the patient’s most recent applicable expressed wishes are incorporated into decision-making discussions. These wishes may be written or verbal. 23
Patient values can be considered from a treatment-specific or goal-oriented perspective. 23 These concepts overlap and may compete within decision making. For example, a patient may wish to have a peaceful death in a hospice devoid of interventions, yet when an untimely sudden event such as myocardial infarction occurs, they may express the wish to have acute interventions in an attempt to recover and subsequently participate in a highly valued family event. Given the uncertainty and complexity of each patient’s unique circumstances, it may take more than one meeting to understand an individual’s wishes, beliefs, and values. Culture significantly affects the patient’s/family’s attitudes and behaviors, and providers must demonstrate cultural competence to acknowledge and respect family values and dynamics. 23
Four clinical principles that are integral to ethical decision making are patient preferences (from the patient’s most recently expressed wishes, beliefs, and values), clinical factors (create a team-based treatment plan), cultural humility (respect individuals and cultures and understand diversity), and creating a moral community (follow commitments to health care). 23 The benefits of this principled approach include enhanced patient satisfaction by improving patient-centered care, the potential to reduce harm, and assistance in conflict resolution. 23 In addition, addressing ethical issues comprehensively improves employee morale and productivity while reducing the risk of litigation and conserving institutional resources. Participation of a clinical ethicist who is well versed in these principles may help with the integration of these principles in the SICU. 23
Develop Flexible Communication Strategies
Communication skills are central to palliative principles of practice. Communication affects quality of care, length of stay, and patient and family satisfaction. 12 End-of-life decisions and communication gaps create primary sources of conflict in ICUs. 24 Good communication likely reduces conflict by clarifying prognoses, patient preferences, family grief reactions, and communication gaps between all persons involved in the care plan. 12
Physicians play a key role in communicating during a patient/SDM decision-making meeting. During these meetings, if the physician depends on one communication style, it may only be effective in some situations but not in others. Therefore, it is important for physicians to develop various approaches to communicating with a variety of patient/SDMs and situations that are encountered in clinical practice. An intensive communication strategy for critically ill patients resulted in a significant increase in physician-led meetings and the early introduction of palliative care and reduced the ICU length of stay in the target group without increasing their likelihood of mortality. 25
There are four described methods physicians use during end-of-life decision-making family meetings: informative, facilitative, collaborative, and directive. 26 Developing the skill to shift between these communication styles as required to support the patient’s/surrogate’s needs is a valuable, advanced physician communication skill. In the facilitative role, providers give medical information, elicit patient values, clarify the role of surrogate decision making, enforce the importance of patient values in decisions, and summarize statements making a link between values and “hypothetical” recommendations. 26 These conversations permit the patient/surrogate the opportunity to contemplate and then participate in developing a treatment plan. Facilitative-type discussions may permit patients and families to gently link medical knowledge to their situation, thus aiding the transition from acute to end of life care. On other occasions, this style may be preferred when the physician or surgeon identifies potential interventions for a patient with considerable prognostic uncertainty. Alternatively, the collaborative role involves providing medical information, eliciting the patient’s values, and making a clear recommendation. 26 This method of participating in family meetings is helpful when the physician feels confident of the best treatment option and when the patient/surrogate asks the physician to provide a recommendation. Uncommonly, the patient/surrogate may want to be the sole decision maker without the advice of the physician. In these situations, the physician participates using an informative role, giving medical information while not engaging in deliberations or making recommendations. 26 The final described communication style is the directive role, in which the provider independently makes a treatment decision, requests acceptance of the plan, offers minimal medical information, and limits deliberation. Facilitative and collaborative roles are most often used. Physicians should be flexible in their approach and meet patients’ and surrogates’ needs during the decision making process. 26
Conduct Family Meetings and Establish Goals of Care
It is important to focus on and clarify the goals of care to improve care in critically ill patients. 27 Decision making conversations can be considered in stages prior to, during, and after the meeting. 28 Prior to the meeting, it is necessary to decide who should be present,29-31 understand fully the patient’s medical issues and investigations or treatments that they may benefit from, 32 determine the potential health care options to offer, review the patient’s social situation and advance care planning documents, and decide the goals of the meeting and the most suitable location for it to occur, During the meeting, after introductions are completed, the physician leader should determine the patient’s/SDM’s understanding and expectations,29,30,33 review the medical summary that was prepared prior to the meeting, support the participants if they have an emotional response, and provide information.29,34 Subsequently, the key therapeutic options should be highlighted, after which the patient’s/SDM’s expressed wishes23,29 and goals of care are definitively clarified. The next step is to “translate the goals into a care plan.” 28 This is a very significant time in the meeting and the need to actualize the care plan is worth stating openly. If consensus cannot be achieved with respect to a new care plan, then more information or time to comprehend the situation may be required to determine the best care plan. 35 Episodically, there are fixed discrepancies in opinions concerning the next steps in the care plan, and conflict resolution strategies are necessary.23,28 In this eventuality, the meeting leader should ensure that there is a follow-up plan and reassure the patient/SDM that care will continue regardless of the goals of care and care plan deliberations. After the meeting, the agreed upon goals of care and care plans should be clearly documented in the patient’s chart.
Provide Family Support During the Dying Process
Sudden critical illness is stressful for family members, and it is associated with heightened psychosocial needs and mental and physical illness. 12 Family members and lay team members are central to decision making and carry the living memory of the event over the long term. Therefore, many institutions are striving to more fully address family needs via lengthened visiting hours and by permitting spiritual care and death rituals prior to and after death.
There is a significant long-term impact on both the patient and family after prolonged critical illness. Family members’ lives are changed because of caregiving, leaving work, delaying education, delaying family members’ care needs, and loss of life savings. 36 Therefore, both patients and families should be supported during and after hospital stay. 36
Family members’ reactions to life-limiting, life-altering events are profound. Caring for the family in the SICU affects their long-term outcomes and their interactions with providers. 37 Grief begins prior to death and influences family actions and decision-making abilities in the ICU. Family members express grief through multiple emotions (despair, anxiety, guilt, anger, hostility, and loneliness), behaviors (agitation, fatigue, and crying), cognitive perceptions (helplessness, hopelessness, and self-blame), and physical changes (sleep loss, exhaustion, and increase in disease). Interactions with staff, conversations, and the methods of breaking news affect grief reactions and are important for providers to consider as quality improvement initiatives are developed.
Establish Reasonable Goals for Life Support and Resuscitation
Resuscitation preferences, advance care plans, prognosis, functional ability, and expected quality of life post–SICU stay are integral components in decision making. There are independent predictors of a do not resuscitate (DNR) status, such as increasing age, comorbidities, and organ failure prior to injury. 38 Patients living with chronic illness or a terminal diagnosis, for example cancer, are more likely to have a DNR status. 39 In contrast, the severity of illness as identified by APACHE scores did not correlate with a DNR order in a recent study in the SICU. 39
Palliative care practitioners recognize that DNR discussions can be more challenging than obtaining consent for intraoperative procedures. 40 DNR consent may be reversed because of an unforeseeable event or iatrogenic concern as a result of the physician’s sense of responsibility, potential litigation, and a belief that the advance directive did not apply in a particular circumstance. 41 Nonetheless, conversations considering withdrawal of life support 42 permit an open discussion recognizing that the patient has a grave and possibly terminal prognosis. This discussion should be followed by a balance of ordinary and medical language while explaining the situation and then an agreement on end-of-life care plans. If there are discrepancies in goals of care between physicians and families, one should explore what the family and providers hope to achieve, such as extending life, restoring health, relieving pain, and avoiding unnecessary suffering. At times, formal conflict resolution methods are required.
Example guidelines for withdrawal of life support policies/protocols are posted on the IPAL-ICU Web site under http://www.capc.org/ipal/ipal-icu/improvement-and-clinical-tools.
Seek Educational Opportunities to Improve End-of-Life Management Skills
Advanced education is necessary to appreciate, learn, and then provide the principles of palliative care practice. Surgeons have opportunities to learn palliative principles of care. An online resource titled Surgical Palliative Care: A Resident’s Guide 43 is endorsed by the American College of Surgeons. It covers fundamental palliative principles, including the following: pain and symptom management (dyspnea, delirium, depression, nausea, and constipation), managing specific patient circumstances (malignant bowel obstruction, artificial hydration, and nutrition), palliative surgery, pediatric palliative care, communication skills (breaking bad news, code status discussions, cultural aspects of care), and referral to specialist palliative care and hospice. 43
Another clear opportunity in the United States is the potential to train leaders in the field of surgical palliative medicine through subspecialty certification in hospice and palliative medicine for surgeons. There are 2 routes of entry: a practice pathway and a training pathway. 44 For those interested in learning more details the overview can be found online at http://www.absurgery.org/default.jsp?certhpm. An additional resource for advancing education and the integration of palliative medicine in critical care is available via the Centre to Advance Palliative Care. 45
Appreciate How Traditional Palliative and Surgical Cultures May Influence Integration of Palliative Care in the SICU
Integrating palliative care into a SICU has unique challenges. 46 Mosenthal et al 46 published a recent article on this issue in Critical Care Medicine, supported by the National Institutes of Health. 46 Table 1 highlights some surgical routines of providing care that may have an impact on the integration of common palliative principles.41,46 -48

Schwarze et al. 47
As an understandable consequence to the concepts outlined in Table 1, many surgeons prefer to retain ownership of the patient, thus controlling principal decision making regarding goals of care and care planning. 46 Preoperatively, surgeons may develop a contractual patient relationship for the acceptance of postoperative life support called surgical buy-in. 47 End-of-life decisions and communication issues among caregivers themselves or caregivers and families are the primary sources of conflict in the ICU. 48 Surgeons may experience significant distress if new information, for example, an advance directive requesting limitation to acute postoperative care, is presented postoperatively. 47 They may feel personal responsibility and emotional distress for poor outcomes, especially for elective procedures when success is expected. 47 If the patient requests unacceptable postoperative limitations, the surgeon may refuse to operate, negotiate for more time, or refuse to consent to withdrawal of life support despite patient/family requests to do so. 47
The Society of Thoracic Surgery has created a national US database that provides detailed risk-prediction models for various cardiac surgical procedures. 49 The purpose of this database includes the benchmarking of performance measures, the provision of feedback on patient care guidelines, and quality improvement. In addition, several states (eg, New York) publish surgeon-specific and institutional-specific mortality rates after cardiac surgery. 50 Unfortunately “shame and blame” public reporting may have a negative impact on the acceptance of dying as a phase of life and on the integration of palliative principles into SICUs. A recent cross-sectional survey has identified components of surgical practice that create conflict and challenges, including deciding goals of care, emphasis on physician profiling, communicating poor outcomes, managing personal discomfort with poor outcomes, and managing the patient’s fears and clinical needs regarding complications. 51
The traditional palliative care culture also demonstrates potential limitations to the integration of palliative care practice in SICUs. The foundational assumptions of the surgical and palliative cultures are illustrated in Table 2. These surgical and palliative care foundational perspectives may complicate the intentions of both the surgical and palliative services and add to the complexity of the situation. A local collaborative multidisciplinary team should consider each service’s unique perspectives as it creates a shared model of care for SICU patients/families.

Helping Resolve Team Conflicts
In our personal experience in the SICU there can be a “creative tension” between the surgical team who performs high-risk operations and the multidisciplinary critical care team who play a major role in postoperative care. We are not unique because surgeons reporting conflict with ICU physicians and nurses is common when determining goals of care for patients with poor postsurgical outcomes. 51 As noted above, most surgeons seek “buy-in” from high-risk surgical patients before they agree to perform complex procedures. 47 If such patients develop serious postoperative complications, it is not uncommon for surgeons to insist on continuing life-sustaining interventions in the ICU, which may not be in line with the patient’s and the family’s preferences. 47 In such instances, the critical care team may be “caught in the cross-fire between patient preferences and the surgical rescue effort,” without having had the opportunity to have witnessed or participated in the preoperative “buy-in” negotiations. 47 Improving practice relationships through building trust, respectful interactions, and accepting diversity has been shown to improve quality of care delivery. 54 Our experience is similar to that described in the literature,10-12,14-16,46,52 which highlights the fact that palliative care physicians have the training and mindset to assist surgical and critical care teams in resolving these conflicts. As a result of palliative collaboration with all team members, the critically ill patient, and the patient’s family, the team is more likely to achieve congruence with respect to the goals of care and resuscitation preferences.
Summary
In conclusion, palliative care consultation can provide a significant, value-added contribution to the care of seriously ill SICU patients with uncertain postoperative outcomes. The principles and cultures of palliative care are complementary to those of surgery and critical care. Palliative care consultants can help both teams provide chronic pain and symptom management to critically ill SICU patients and can help clarify the patient’s and family’s wishes, beliefs, and values, which have an enduring impact on clinical decision making. In addition, by participating in meetings with a critically ill patient’s family, palliative care providers can help establish the goals of care and achieve consensus as to whether or not aggressive resuscitative care is appropriate. Finally, we believe that palliative care consultants can be very helpful in resolving conflicts between surgical and critical care team members, thus providing long-term benefits to SICU patients, their families, and the overall functioning and culture of the unit.
