Interventions to Improve Care during Withdrawal of Life-Sustaining Treatments

Mechanical ventilation withdrawal as a palliative procedure in a Brazilian intensive care unit

Objective

To describe the characteristics and outcomes of patients undergoing mechanical ventilation withdrawal and to compare them to mechanically ventilated patients with limitations (withhold or withdrawal) of life-sustaining therapies but who did not undergo mechanical ventilation withdrawal.

Methods

This was a retrospective cohort study from January 2014 to December 2018 of mechanically ventilated patients with any organ support limitation admitted to a single intensive care unit. We compared patients who underwent mechanical ventilation withdrawal and those who did not regarding intensive care unit and hospital mortality and length of stay in both an unadjusted analysis and a propensity score matched subsample. We also analyzed the time from mechanical ventilation withdrawal to death.

Results

Out of 282 patients with life-sustaining therapy limitations, 31 (11%) underwent mechanical ventilation withdrawal. There was no baseline difference between groups. Intensive care unit and hospital mortality rates were 71% versus 57% and 93% versus 80%, respectively, among patients who underwent mechanical ventilation withdrawal and those who did not. The median intensive care unit length of stay was 7 versus 8 days (p = 0.6), and the hospital length of stay was 9 versus 15 days (p = 0.015). Hospital mortality was not significantly different (25/31; 81% versus 29/31; 93%; p = 0.26) after matching. The median time from mechanical ventilation withdrawal until death was 2 days [0 - 5], and 10/31 (32%) patients died within 24 hours after mechanical ventilation withdrawal.

Conclusion

In this Brazilian report, mechanical ventilation withdrawal represented 11% of all patients with treatment limitations and was not associated with increased hospital mortality after propensity score matching on relevant covariates.

Incidence and Risk Model Development for Severe Tachypnea Following Terminal Extubation

BACKGROUND

Palliative ventilator withdrawal (PVW) in the ICU is a common occurrence.

RESEARCH QUESTION

The goal of this study was to measure the rate of severe tachypnea as a proxy for dyspnea and to identify characteristics associated with episodes of tachypnea.

STUDY DESIGN AND METHODS

This study assessed a retrospective cohort of ICU patients from 2008 to 2012 mechanically ventilated at a single academic medical center who underwent PVW. The primary outcome of at least one episode of severe tachypnea (respiratory rate > 30 breaths/min) within 6 h after PVW was measured by using detailed physiologic and medical record data. Multivariable logistic regression was used to examine the association between patient and treatment characteristics with the occurrence of a severe episode of tachypnea post extubation.

RESULTS

Among 822 patients undergoing PVW, 19% and 30% had an episode of severe tachypnea during the 1-h and 6-h postextubation period, respectively. Within 1 h postextubation, patients with the following characteristics were more likely to experience tachypnea: no pre-extubation opiates (adjusted OR [aOR], 2.08; 95% CI, 1.03-4.19), lung injury (aOR, 3.33; 95% CI, 2.19-5.04), Glasgow Coma Scale score > 8 (aOR, 2.21; 95% CI, 1.30-3.77), and no postextubation opiates (aOR, 1.90; 95% CI, 1.19-3.00).

INTERPRETATION

Up to one-third of ICU patients undergoing PVW experience severe tachypnea. Administration of pre-extubation opiates (anticipatory dosing) represents a key modifiable factor that may reduce poor symptom control.

Levels of Intervention: How Are They Used in Quebec Hospitals?

In order to promote better practices and communication around end-of-life decision-making, several Canadian hospitals in the province of Quebec have developed a tool called "Levels of Intervention" (LOI). No work to date has been published demonstrating improvement since these forms were implemented. The purpose of the present study was to obtain information about the use of LOI forms across Quebec hospitals and to identify gaps in practice as well as areas for improvement. A retrospective study was undertaken of 299 charts of patients who had died in three Quebec hospitals with a LOI ordered. Results were analysed through a principlism ethical framework. High compliance with the level of intervention ordered at the time of death was recorded, as well as high involvement of patient and/or family, demonstrating the efficiency of LOI in promoting respect for autonomy. Other results show delays in end-of-life care discussions in the course of the hospitalization. Only a small proportion of patients who died had a palliative care consultation, which may reflect equity issues in access to care. This study highlights the importance of the LOI in Quebec and the role it is playing in respect for end-of-life preferences as well as in the involvement of patients and families in the decision-making process. Training specific to end-of-life decision-making conversations would help support the LOI form's use, as would developing provincial or national guidelines on the use of LOI to standardize organizational policies and practice around end-of-life care.

Withdrawal of life-sustaining treatment: a case study

Withdrawal of life support is an option for patients with prolonged mechanical ventilation when all attempts at weaning have failed and it is deemed futile to continue the therapy, when quality of life is unacceptable, or when it is perceived that the patient is suffering. The purpose of this article is to present the nursing aspects of managing an adult patient undergoing the withdrawal of mechanical ventilation as an end-of-life procedure. Withdrawal of mechanical ventilation is a complex and difficult process that requires meticulous planning and management. Conferences with the patient and the patient's family are critical to addressing emotional support and ensuring that everyone understands the process and is provided an opportunity to gather information. Clear communication with patients and their families can ensure that the process goes smoothly. Having an organized approach can ensure that patients experience a peaceful death and staff experience closure regarding the event.

Palliative critical care in the intensive care unit: A 2011 perspective

Pain relief and palliative care play an increasingly important role in the overall approach to critically ill and injured patients. Despite significant progress in clinical patient care, our understanding of death and the dying process remains limited. For various reasons, people tend to delay facing questions associated with end-of-life, and the fear of the unknown often creates an environment of avoidance and an atmosphere of taboo. The topic of end-of-life care is multifaceted. It incorporates medical, ethical, spiritual, and religious aspects, among many others. Our ability to sustain the lives of the critically ill may be complicated by continuing life support in medically futile scenarios. This article, as well as the remainder of the IJCIIS Symposium on End-of-Life in Trauma/Intensive Care Unit, will explore the most important issues in the field of modern end-of-life care and palliative medicine, with a focus on critically ill and injured patients.

Life-sustaining treatment decisions in the ICU for patients with ESLD: a prospective investigation

We conducted a prospective study in the ICU of life-sustaining treatment and comfort care decisions over time in patients with end-stage liver disease (ESLD) from the perspectives of patients, family members, and healthcare professionals. Six patients with ESLD, 19 family members, and 122 professionals participated. The overarching theme describing the decision-making process was "on the train." Four sub-themes positioned patients and family members as passengers with limited control, unable to fully understand the decision-making process. Findings suggest that including patients and family members in non-immediate life-saving decisions and verifying early on their understanding may help to improve the decision-making process.

Exploring the quality of dying of patients with chronic obstructive pulmonary disease in the intensive care unit: a mixed methods study

RATIONALE FOR THE STUDY

Improving the quality of end-of-life (EOL) care in critical care settings is a high priority. Patients with advanced chronic obstructive pulmonary disease (COPD) are frequently admitted to and die in critical care units. To date, there has been little research examining the quality of EOL care for this unique subpopulation of critical care patients.

AIMS

The aims of this study were (a) to examine critical care clinician perspectives on the quality of dying of patients with COPD and (b) to compare nurse ratings of the quality of dying and death between patients with COPD with those who died from other illnesses in critical care settings.

DESIGN AND SAMPLE

A sequential mixed method design was used. Three focus groups provided data describing the EOL care provided to patients with COPD dying in the intensive care unit (ICU). Nurses caring for patients who died in the ICU completed a previously validated, cross-sectional survey (Quality of Dying and Death) rating the quality of dying for 103 patients.

DATA ANALYSIS

Thematic analysis was used to analyse the focus group data. Total and item scores for 34 patients who had died in the ICU with COPD were compared with those for 69 patients who died from other causes.

RESULTS

Three primary themes emerged from the qualitative data are as follows: managing difficult symptoms, questioning the appropriateness of care and establishing care priorities. Ratings for the quality of dying were significantly lower for patients with COPD than for those who died from other causes on several survey items, including dyspnoea, anxiety and the belief that the patient had been kept alive too long. The qualitative data allowed for in-depth explication of the survey results.

CONCLUSIONS

Attention to the management of dyspnoea, anxiety and treatment decision-making are priority concerns when providing EOL care in the ICU to patients with COPD.

Metasynthesis: withdrawing life-sustaining treatments: the experience of family decision-makers

AIM

The present study was undertaken to synthesise findings from qualitative investigations of family participation in decisions to withdraw and/or withhold life-sustaining treatment from a seriously ill family member.

BACKGROUND

As a consequence of increasing effectiveness and sophistication of available medical interventions, death is commonly preceded by a decision to withdraw or withhold potentially life-sustaining treatments. These decisions take place in a bioethical context characterised by the pre-eminence of self-determination, but patients are typically too ill to make their own decisions. Thus, family members are called upon to participate in these morally consequential decisions on the patient's behalf.

DESIGN

Metasynthesis.

METHOD

Metasynthesis is a form of inquiry that provides for integration of qualitative studies' findings to strengthen knowledge for practice and advance theoretical development. This metasynthesis was conducted using the constant comparative methods of grounded theory.

RESULTS

Family members engage in a process of participation in decision-making that is comprised of three major categories: reframing reality, relating and integrating. Surrogates used both cues and information as they reframed their understanding of the patient's status. Relationships with providers and with other family members powerfully influenced the decision-making process. Integrating was characterised by reconciling and going forward. This part of the process has both intrapersonal and interpersonal aspects and describes how family decision-makers find meaning in their experience and move forward in their lives.

CONCLUSIONS

This synthesis provides a more comprehensive and empirically supported understanding of family members' experiences as they participate in treatment decisions for dying family members. Relevance to clinical practice. This metasynthesis provides evidence to improve family care during treatment withdrawal/withholding decision-making and a theoretical model that can be used to guide creation of clinical practice guidelines. Through increased understanding of family members' experiences, clinicians can more effectively support family decision-making processes.

Ethics review: end of life legislation--the French model

French law 2005-370 of April 22, 2005 (Leonetti's law) brings new rights to patients and clarifies medical practices regarding end of life care. This new law prohibits unreasonable obstinacy in investigations or therapeutics and authorizes the withholding or withdrawal of treatments when they appear "useless, disproportionate or having no other effect than solely the artificial preservation of life". Relief from pain is a fundamental right of patients. With regard to pain control, the law also allows doctors to dispense to patients "in an advanced or final phase of a serious and incurable affliction" anti-pain treatments as needed, even if these treatments, as a side effect, hasten their death. The drafting of advance directives regarding end of life constitutes a new right of patients. The decision to withdraw or withhold a treatment from a patient unable to express their will has to take into account the wishes they might have expressed through advance directives, and/or the wishes of a trusted person or, lastly, of the family. Before making any decision, physicians should respect a collegial medical procedure. Euthanasia defined as the act of terminating one's life on a patient's explicit request remains illegal.

Implementation of ICU palliative care guidelines and procedures: a quality improvement initiative following an investigation of alleged euthanasia

Ethical conflicts are commonly encountered in the course of delivering end-of-life care in the ICU. Some ethical concerns have legal dimensions, including concerns about inappropriate hastening of death. Despite these concerns, many ICUs do not have explicit policies and procedures for withdrawal of life-sustaining treatments. We describe a US Office of Inspector General (OIG) investigation of end-of-life care practices in our ICU. The investigation focused on care delivered to four critically ill patients with terminal diseases and an ICU nurse's concern that the patients had been subjected to euthanasia. The OIG investigation also assessed the validity of allegations that patient flow in and out of our ICU was inappropriately influenced by scheduled surgeries and that end-of-life care policies in our ICU were not clear. Although the investigation did not substantiate the allegations of euthanasia or inappropriate ICU patient flow, it did find that the policies that discuss end-of-life care issues were not clear and allowed for wide-ranging interpretations. Acting on the OIG recommendations, we developed a quality improvement initiative addressing end-of-life care in our ICU, intended to enhance communication and understanding about palliative care practices in our ICU, to prevent ethical conflicts surrounding end-of-life care, and to improve patient care. The initiative included the introduction of newly developed ICU comfort care guidelines, a physician order set, and a physician template note. Additionally, we implemented an educational program for ICU staff. Staff feedback regarding the initiative has been highly favorable, and the nurse whose concerns led to the investigation was satisfied not only with the investigation but also the policies and procedures that were subsequently introduced in our ICU.

End-of-life decisions in pediatric intensive care. Recommendations of the Italian Society of Neonatal and Pediatric Anesthesia and Intensive Care (SARNePI)

End-of-life decisions represent one of the most complex and challenging issues in pediatric intensive care. These recommendations aim to offer Italian pediatric intensive care unit (PICU) teams a framework for the end-of-life decision-making process. The paper proposes a process based on the principle that the use of a diagnostic or therapeutic tool must comply with a 'criterion of proportionality'. Appropriately informed parents, as natural interpreters and advocates of the best interests of their child, can contribute in assessing the burdensomeness of the treatment and determining its proportionality. The decision to limit, withdraw or withhold life-sustaining treatments considered disproportionate represents a clinically and ethically correct choice. This decision should be made (a) collectively by PICU team and the other caregivers, (b) with the explicit involvement of parents, and (c) noting in the patient's clinical record the decisions taken and the reasons behind them. The withdrawing or withholding of life support can never entail the abandonment of the patient nor the withdrawal of any therapy aimed at treating any form of suffering. No action aimed at deliberately hastening the death of the patient is ever acceptable. These recommendations advocate a decision as far as possible shared by patient (whenever feasible), parents and caregivers. Ensuring that all involved are kept fully informed and that there is open and timely communication between them is the key to achieving this. It is the physician in charge of the patient's care and the head of the unit who bear the main responsibility for the final decision.

Integrating palliative and critical care: evaluation of a quality-improvement intervention

RATIONALE

Palliative care in the intensive care unit (ICU) is an important focus for quality improvement.

OBJECTIVES

To evaluate the effectiveness of a multi-faceted quality improvement intervention to improve palliative care in the ICU.

METHODS

We performed a single-hospital, before-after study of a quality-improvement intervention to improve palliative care in the ICU. The intervention consisted of clinician education, local champions, academic detailing, feedback to clinicians, and system support. Consecutive patients who died in the ICU were identified pre- (n = 253) and postintervention (n = 337). Families completed Family Satisfaction in the Intensive Care Unit (FS-ICU) and Quality of Dying and Death (QODD) surveys. Nurses completed the QODD. The QODD and FS-ICU were scored from 0 to 100. We used Mann-Whitney tests to assess family results and hierarchical linear modeling for nurse results.

MEASUREMENTS AND MAIN RESULTS

There were 590 patients who died in the ICU or within 24 hours of transfer; 496 had an identified family member. The response rate for family members was 55% (275 of 496) and for nurses, 89% (523/590). The primary outcome, the family QODD, showed a trend toward improvement (pre, 62.3; post, 67.1), but was not statistically significant (P = 0.09). Family satisfaction increased but not significantly. The nurse QODD showed significant improvement (pre, 63.1; post, 67.1; P < 0.01) and there was a significant reduction in ICU days before death (pre, 7.2; post, 5.8; P < 0.01).

CONCLUSIONS

We found no significant improvement in family-assessed quality of dying or in family satisfaction with care, we found but significant improvement in nurse-assessed quality of dying and reduction in ICU length of stay with an intervention to integrate palliative care in the ICU. Improving family ratings may require interventions that have more direct contact with family members.

Preparing Families of Intensive Care Patients for Withdrawal of Life Support: A Pilot Study

Background Most deaths in intensive care occur after withdrawal of life support. Although preparation of patients’ families is recommended, the specific information required has not been theoretically developed or tested.

Objective To assess the feasibility of testing 4 tailored messages to prepare families of patients having a planned withdrawal of life support, to assess barriers to conducting such a study, and to obtain preliminary data on measurable effects that could be used to compare such preparation with usual care. Self-regulation theory was used to structure the messages.

Methods Families were randomly assigned to usual care (n=10) or to an intervention group (n=10) that received 1 of 4 tailored messages to prepare them for withdrawal of life support. They were contacted 2 to 4 weeks later to complete the Profile of Mood States and to give their evaluation of the experience, inclusive of the information received.

Results Compared with the usual-care group, the intervention group was significantly more satisfied with the information they received and understood better what was to happen. The intervention group had lower negative mood scores and higher positive mood scores than did the usual-care group, although the difference was not significant. Unsolicited comments by the usual-care participants were requests for the specific information that had been received by the intervention group.

Conclusions The information provided was considered helpful. A larger sample might yield more significant differences. Further work is needed on other aspects of preparation such as healthcare support, spiritual issues, and preparation for funeral arrangements.

Family support at end of life

Much of the literature for end of life in the intensive care unit focuses on patients and their treatment. Families are usually present and should be a focus, as well as a resource, in end-of-life plans. Using categories from a recently published Society of Critical Care Medicine guideline on family support during an intensive care unit stay and 7 end-of-life domains, literature retrieved since 2000 was summarized. Topics addressed are decision making, spiritual and cultural support, emotional and practical support of families, including visitation and family preparation for death, and continuity of care.

Surviving Sepsis Campaign: international guidelines for management of severe sepsis and septic shock: 2008

OBJECTIVE

To provide an update to the original Surviving Sepsis Campaign clinical management guidelines, "Surviving Sepsis Campaign guidelines for management of severe sepsis and septic shock," published in 2004.

DESIGN

Modified Delphi method with a consensus conference of 55 international experts, several subsequent meetings of subgroups and key individuals, teleconferences, and electronic-based discussion among subgroups and among the entire committee. This process was conducted independently of any industry funding.

METHODS

We used the GRADE system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations. A strong recommendation indicates that an intervention's desirable effects clearly outweigh its undesirable effects (risk, burden, cost), or clearly do not. Weak recommendations indicate that the tradeoff between desirable and undesirable effects is less clear. The grade of strong or weak is considered of greater clinical importance than a difference in letter level of quality of evidence. In areas without complete agreement, a formal process of resolution was developed and applied. Recommendations are grouped into those directly targeting severe sepsis, recommendations targeting general care of the critically ill patient that are considered high priority in severe sepsis, and pediatric considerations.

RESULTS

Key recommendations, listed by category, include: early goal-directed resuscitation of the septic patient during the first 6 hrs after recognition (1C); blood cultures prior to antibiotic therapy (1C); imaging studies performed promptly to confirm potential source of infection (1C); administration of broad-spectrum antibiotic therapy within 1 hr of diagnosis of septic shock (1B) and severe sepsis without septic shock (1D); reassessment of antibiotic therapy with microbiology and clinical data to narrow coverage, when appropriate (1C); a usual 7-10 days of antibiotic therapy guided by clinical response (1D); source control with attention to the balance of risks and benefits of the chosen method (1C); administration of either crystalloid or colloid fluid resuscitation (1B); fluid challenge to restore mean circulating filling pressure (1C); reduction in rate of fluid administration with rising filing pressures and no improvement in tissue perfusion (1D); vasopressor preference for norepinephrine or dopamine to maintain an initial target of mean arterial pressure > or = 65 mm Hg (1C); dobutamine inotropic therapy when cardiac output remains low despite fluid resuscitation and combined inotropic/vasopressor therapy (1C); stress-dose steroid therapy given only in septic shock after blood pressure is identified to be poorly responsive to fluid and vasopressor therapy (2C); recombinant activated protein C in patients with severe sepsis and clinical assessment of high risk for death (2B except 2C for post-operative patients). In the absence of tissue hypoperfusion, coronary artery disease, or acute hemorrhage, target a hemoglobin of 7-9 g/dL (1B); a low tidal volume (1B) and limitation of inspiratory plateau pressure strategy (1C) for acute lung injury (ALI)/acute respiratory distress syndrome (ARDS); application of at least a minimal amount of positive end-expiratory pressure in acute lung injury (1C); head of bed elevation in mechanically ventilated patients unless contraindicated (1B); avoiding routine use of pulmonary artery catheters in ALI/ARDS (1A); to decrease days of mechanical ventilation and ICU length of stay, a conservative fluid strategy for patients with established ALI/ARDS who are not in shock (1C); protocols for weaning and sedation/analgesia (1B); using either intermittent bolus sedation or continuous infusion sedation with daily interruptions or lightening (1B); avoidance of neuromuscular blockers, if at all possible (1B); institution of glycemic control (1B) targeting a blood glucose < 150 mg/dL after initial stabilization ( 2C ); equivalency of continuous veno-veno hemofiltration or intermittent hemodialysis (2B); prophylaxis for deep vein thrombosis (1A); use of stress ulcer prophylaxis to prevent upper GI bleeding using H2 blockers (1A) or proton pump inhibitors (1B); and consideration of limitation of support where appropriate (1D). Recommendations specific to pediatric severe sepsis include: greater use of physical examination therapeutic end points (2C); dopamine as the first drug of choice for hypotension (2C); steroids only in children with suspected or proven adrenal insufficiency (2C); a recommendation against the use of recombinant activated protein C in children (1B).

CONCLUSION

There was strong agreement among a large cohort of international experts regarding many level 1 recommendations for the best current care of patients with severe sepsis. Evidenced-based recommendations regarding the acute management of sepsis and septic shock are the first step toward improved outcomes for this important group of critically ill patients.

Attitudes and behaviors of Japanese physicians concerning withholding and withdrawal of life-sustaining treatment for end-of-life patients: results from an Internet survey

BACKGROUND

Evidence concerning how Japanese physicians think and behave in specific clinical situations that involve withholding or withdrawal of medical interventions for end-of-life or frail elderly patients is yet insufficient.

METHODS

To analyze decisions and actions concerning the withholding/withdrawal of life-support care by Japanese physicians, we conducted cross-sectional web-based internet survey presenting three scenarios involving an elderly comatose patient following a severe stroke. Volunteer physicians were recruited for the survey through mailing lists and medical journals. The respondents answered questions concerning attitudes and behaviors regarding decision-making for the withholding/withdrawal of life-support care, namely, the initiation/withdrawal of tube feeding and respirator attachment.

RESULTS

Of the 304 responses analyzed, a majority felt that tube feeding should be initiated in these scenarios. Only 18% felt that a respirator should be attached when the patient had severe pneumonia and respiratory failure. Over half the respondents felt that tube feeding should not be withdrawn when the coma extended beyond 6 months. Only 11% responded that they actually withdrew tube feeding. Half the respondents perceived tube feeding in such a patient as a "life-sustaining treatment," whereas the other half disagreed. Physicians seeking clinical ethics consultation supported the withdrawal of tube feeding (OR, 6.4; 95% CI, 2.5-16.3; P < 0.001).

CONCLUSION

Physicians tend to harbor greater negative attitudes toward the withdrawal of life-support care than its withholding. On the other hand, they favor withholding invasive life-sustaining treatments such as the attachment of a respirator over less invasive and long-term treatments such as tube feeding. Discrepancies were demonstrated between attitudes and actual behaviors. Physicians may need systematic support for appropriate decision-making for end-of-life care.

End-of-life care in the intensive care unit: State of the art in 2006

Evidence suggests that change is occurring in end-of-life care in the intensive care unit (ICU). There is a growing need and appreciation for the importance of education for the multidisciplinary team, but particularly for physicians, in gaining communication skills to improve the quality of end-of-life care and provide palliative care in the ICU. Studies have indicated that families are unhappy with the communication they receive when a family member is in the ICU. Evidence also suggests that families want to be involved in decisions about their loved one's care. Interventions have been tested in numerous ICUs that others can evaluate for application to their own facility in an attempt to create a global standard for end-of-life care in the ICU. Quality indicators have been defined, and an audit tool can help assess levels of performance.
