Palliative care interventions in intensive care unit patients

Critical care nurses' experiences of ethical challenges in end-of-life care

BACKGROUND

In Swedish intensive care units, nine percent of patients do not survive despite receiving advanced life-sustaining treatments. As these patients transition to end-of-life care, ethical considerations may become paramount.

AIM

To explore the ethical challenges that critical care nurses encounter when caring for patients at the end of life in an intensive care context.

RESEARCH DESIGN

The study used a qualitative approach with an interpretive descriptive design.

RESEARCH CONTEXT AND PARTICIPANTS

Twenty critical care nurses from eight intensive care units in an urban region in Sweden were interviewed, predominately women with a median age of fifty-one years.

ETHICAL CONSIDERATIONS

This study was approved by The Swedish Ethics Review Authority.

FINDINGS

Critical care nurses described encountering ethical challenges when life-sustaining treatments persisted to patients with minimal survival prospects and when administering pain-relieving medications that could inadvertently hasten patients' deaths. Challenges also arose when patients expressed a desire to withdraw life-sustaining treatments despite the possibility of recovery, or when family members wanted to shield patients from information about a poor prognosis; these wishes occasionally conflicted with healthcare guidelines. The critical care nurses also encountered ethical challenges when caring for potential organ donors, highlighting the balance between organ preservation and maintaining patient dignity.

CONCLUSION

Critical care nurses encountered ethical challenges when caring for patients at the end of life. They described issues ranging from life-sustaining treatments and administration of pain-relief, to patient preferences and organ donation considerations. Addressing these ethical challenges is essential for delivering compassionate person-centered care, and supporting family members during end-of-life care in an intensive care context.

The impact of targeted nursing intervention on postoperative medication adherence, quality of life, and psychological flexibility of thyroid cancer patients

OBJECTIVE

To explore the effect of targeted nursing intervention on postoperative medication adherence, quality of life, and psychological flexibility of patients with thyroid cancer (TC).

METHODS

A total of 330 patients were randomly divided into a Control group and an Intervention group (cases in the Intervention group were given targeted nursing interventions and cases in the Control group were given routine health education), with 165 cases in each group. In the Intervention group, targeted dietary and psychological nursing interventions were conducted on TC patients, and the effects of targeted nursing interventions on the quality of life, medication adherence, and psychological flexibility were compared through the SF-36 Short Form Health Survey, Morisky Medication Adherence Scale and Psychological Resilience Scale with the Control group. Univariate analysis and multiple stepwise regression analysis were performed to analyze the influencing factors of psychological flexibility in patients after nursing intervention.

RESULTS

The Intervention group patients, after nursing intervention, in terms of life quality, scores of social function, physical function, and mental function were all higher than those of the Control group. Note that, 160 patients in the Intervention group (96.97%) had better treatment scores, which was significantly higher than that in the Control group (84.24%). The scores of mental resilience in the Intervention group reached 67.82 ± 13.85, and the two items of resilience, control, and optimism were significantly improved compared with the Control group (p < 0.05). Factors that had greater impacts on the psychological flexibility of TC patients were: age, education, per capita monthly income, and family residence.

CONCLUSION

Targeted nursing intervention had positive promoting effects on postoperative medication adherence, quality of life, and psychological flexibility of TC patients.

The Real-World Effect of Early Screening for Palliative Care Criteria in a Medical Intensive Care Unit: An Instrumental Variable Analysis

Rationale: Early identification of intensive care unit (ICU) patients likely to benefit from specialist palliative care could reduce the time such patients spend in the ICU receiving care inconsistent with their goals. Objectives: To evaluate the real-world effects of early screening for palliative care criteria in a medical ICU. Methods: We performed a retrospective cohort study in adults admitted to the ICU using a causal inference approach with instrumental variable analysis. The intervention consisted of screening ICU admissions for palliative care trigger conditions and, if present, offering specialist palliative care consultation, which could be accepted or declined by the ICU. We evaluated specialist palliative care use in pre and postimplementation cohorts from the year before and after screening implementation began (October 2022). In the postimplementation cohort, we compared use of specialist palliative care in those who received early screening versus not. We then estimated the effect of early screening on the primary outcome of days to do-not-resuscitate (DNR) code status or ICU discharge, with death without a DNR order placed at the 99th percentile of the days to DNR or ICU discharge distribution. Secondary outcomes included: DNR order, ICU and hospital lengths of stay, hospice discharge, and mortality metrics. To address unmeasured confounding, we used two-stage least-squares instrumental variables analysis. The instrument, which predicts early screening, comprised weekend versus weekday admission and number of patients meeting palliative care criteria on a patient's ICU Days 1 and 2. Results: Among 1,282 postimplementation admissions, 626 (45%) received early screening, and 398 (28%) received specialty palliative consultation. Early receipt of specialist palliative care was higher in patients who received early screening versus not (17% vs. 1%; P < 0.001), and overall use of specialty palliative care was higher after versus before screening implementation (28% vs. 15%; P < 0.001). In the postimplementation cohort, there were no statistically significant effects of early screening on the primary outcome of days to DNR or ICU discharge (15% relative increase; 95% confidence interval, -11% to +48%) or other secondary outcomes. Conclusions: Despite significantly increased specialty palliative care consultation, there was no evidence that early screening for palliative care criteria affected time to DNR/ICU discharge or other secondary outcomes.

Palliative Care and Intensivists' Different Perspectives on Specialist Palliative Care Engagement in Extracorporeal Membrane Oxygenation Care

Introduction: There is limited understanding of critical care (CC) and specialist palliative care (SPC) professionals' perceptions regarding the role and utility of SPC for patients on extracorporeal membrane oxygenation (ECMO). Methods: An 18-item survey was distributed via convenience sampling and snowballing strategies to CC and SPC attendings working with veno-venous ECMO patients. Results: A total of 75 surveys were completed. Many CC professionals indicated that SPC consultation was not routinely helpful (5% vs. 71%, p < 0.05). Responses varied on the appropriateness of discussing SPC with patients/families prognosis (81% SPC vs. 47% CC, p < 0.05), end-of-life preferences (100% vs. 62%, p < 0.05), goals of care (95% vs. 58%, p < 0.05), and code status (76% vs. 43%, p < 0.05). Conclusion: Most respondents indicated that psychosocial support and multidisciplinary team collaborations were within the SPC scope. CC professionals were less likely to indicate that discussion of the care trajectory with patients/families was within SPC scope.

Mobile App-Facilitated Collaborative Palliative Care Intervention for Critically Ill Older Adults: A Randomized Clinical Trial

Importance

Few person-centered, scalable models of collaborative intensive care unit (ICU) clinician-palliative care specialist care exist.

Objective

To evaluate the effect of a collaborative palliative care intervention compared to usual care among family members of patients in the ICU.

Design, Setting, and Participants

This parallel-group randomized clinical trial with patient-level randomization was conducted between April 2021 and September 2023. The study was set at 6 medical and surgical ICUs in 1 academic hospital and 1 community hospital. The study participants included critically ill older adult patients with 1 of 11 poor outcome phenotypes, their family members with elevated palliative care needs, and their attending ICU physicians.

Intervention

An automated electronic health record-integrated, mobile application-based communication platform that displayed family-reported needs over 7 days, coached ICU attending physicians on addressing needs, and prompted palliative care consultation if needs were not reduced within 3 study days.

Main Outcomes and Measures

The primary outcome was change in the family-reported Needs at the End-of-Life Screening Tool (NEST) score between study days 1 and 3. The 13-item NEST score is a number between 0 and 130, with higher scores indicating a greater need. Secondary outcomes included quality of communication and goal of care concordance, as well as 3-month psychological distress.

Results

Of 151 family members, the mean (SD) age was 57.4 (12.9) years, and 110 (72.9%) were female. Of 151 patients, the mean (SD) age was 69.8 (9.7) years, and 86 (57.0%) were male. Thirty-five ICU physicians were male (68.6%). Seventy-six patients were randomized to the intervention group and 75 to the control group. Treatment group differences in estimated mean NEST scores were similar at 3 days between the intervention and control groups (-3.1 vs -2.0, respectively; estimated mean difference in differences, -1.3 points [95% CI, -6.0 to 3.5]) and 7 days (-2.3 vs -2.2, respectively; estimated mean difference in differences, 0 points [95% CI, -6.2 to 6.2]). Median (IQR) need scores were lower among individuals who remained in the ICU at day 3 for intervention participants vs controls (24.5 [16.5-34.5] vs 27.5 [13.0-40.0], respectively); median (IQR) need scores were also lower among those who remained in the ICU at day 7 for intervention vs controls (22.0 [11.0-35.0] vs 28.0 [14.0-35.0], respectively). Goal concordance, quality of communication, and psychological distress symptoms did not differ. Twenty-nine intervention participants (38.2%) had palliative care consultations, compared to only 3 (4.0%) among controls, (P < .001); 66 intervention participants (87.0%) had a family meeting, compared to 48 (64.0%) among controls (P = .001).

Conclusions and Relevance

In this randomized clinical trial, a collaborative, person-centered, ICU-based palliative care intervention had no effect on palliative care needs or psychological distress compared to usual care despite a higher frequency of palliative care consultations and family meetings among intervention participants.

Understanding Staff Needs for Improving End-Of-Life Care in Critical Care Units: A Qualitative Focus Group Analysis and Service Evaluation

Objectives: Critical care is a place of frequent death, up to a quarter of those admitted die during admission. Caring for dying people provides many challenges, practically, professionally and personally. The aim of this study was to better understand the perspectives of staff caring for dying people in critical care and identify their priorities for improvement. Method: Three multidisciplinary focus groups of critical care staff at a large central London hospitals trust were facilitated with a semi structured format and digitally transcribed. Inductive thematic analysis was conducted to extract themes. Results: N = 34 (18 nursing, 7 allied health professionals, 6 medical, 3 clerical/administrative). The five themes were structured as priority statements: "We need to recognise" included the subthemes of being "sick enough to die" and potential rapid deteriorations in this setting; "We need to understand" with subthemes of perspectives on dying and prioritising time for conversations; "We need to connect" with subthemes of therapeutic relationship and physical presence; "We need to collaborate" with subthemes of critical care working and empowerment, and cross teams working; "We need support" with themes of experiencing support and making time to support others. Conclusion: We present an approach to identifying critical care departmental priorities for an end-of-life care improvement programme. The themes extracted will be used to evaluate systems for dying in critical care, aiming to empower staff to provide excellent care every time they look after a dying person. Relevance to Practice: This service evaluation identifies key priorities among critical care staff regarding end-of-life care. The insights can guide service improvements, such as tailored training and enhanced support for staff, to ensure better communication, collaboration, and quality care for patients at the end of life.

SAFE-GOALS: a protocol for goals of care discussions in the intensive care unit

Summary

Introduction

In critical care, there is often a lack of understanding regarding patient preferences toward end-of-life care. Goals of care discussions are poorly defined and inhibited by clinician apprehension, prognostic uncertainty, and discomfort from both sides. In the delivery of bad news, protocol-based discussions have proven beneficial, yet no such protocol exists for goals of care discussions in the intensive care unit (ICU). We therefore assembled a multidisciplinary team to define a specific protocol dedicated to leading goals of care discussions in the ICU setting.

SAFE-GOALS protocol

S: set upA: acknowledgmentF: family understandingE: events of hospital courseG: get to know the patientO: optionsAL: active listening and discussionS: steps going forward.

Conclusion

This protocol provides a framework for leading goals of care conversations in the ICU. Specific training should be incorporated and better emphasized in the modern medical education.

What Helps or Hinders End-of-Life Care in Adult Intensive Care Units in Saudi Arabia? A Mixed-Methods Study Protocol

Background: In the intensive care unit, many patients are dying despite advanced therapeutic technology and optimized treatment. The critical care team is expected to deliver end-of-life care for the dying patient and their family. However, it is challenging to provide adequate support to families due to the ideas and emotions associated with the end of life. This can be influenced by different beliefs and cultures among patients and healthcare professionals. Added to this, research about end-of-life practices in intensive care units in Saudi Arabia is limited. Therefore, this study protocol aims to examine: (1) What end-of-life care is provided by healthcare teams in adult intensive care units in Saudi Arabia? (2) What helps or hinders effective end-of-life care in adult intensive care units in Saudi Arabia? Method: This study will use a mixed-methods, sequential, explanatory design consisting of two phases. Phase 1 will include a cross-sectional study design with a convenience sample of approximately 400 healthcare providers who will be invited from three military hospitals in Saud Arabia. the Palliative and End-of-Life Care Index (PEOL Care Index) will be used to assess palliative and end-of-life care education, practice, and perceived competence among the staff. Additionally, a questionnaire on the barriers to optimal end-of-life care and the perceived benefit of potential strategies to improve end-of-life care will be applied to obtain the views of managers. Phase 2 of the study will be a qualitative descriptive design involving semi-structured interviews with healthcare providers, managers, and bereaved family members. Conclusion: The study findings will contribute to understanding current practice in relation to palliative and end-of-life care in intensive care units in Saudi Arabia. It will provide valuable insight into barriers to and facilitators of care, which will help to develop strategies and interventions to improve the quality of end-of-life practices in ICUs. In addition, this research will provide significant information regarding family members' experiences of end-of-life care provided to their relatives.

Implementing palliative care in the intensive care unit: a systematic review and mapping of knowledge to the implementation research logic model

PURPOSE

The importance and effectiveness of palliative care (PC) in intensive care units (ICU) are known. Less is known about the implementation and integration of ICU-based PC interventions. This systematic review aims to use a modified implementation research logic model (IRLM) to identify, map, and synthesise evidence on implementation of ICU-PC (primary and/or specialist) interventions.

METHODS

This systematic review used an adapted Smith's IRLM to understand relationships between implementation factors-determinants (barriers and facilitators), strategies, and mechanisms-and report intervention characteristics and outcomes. Searches up to 2nd December 2023, of MEDLINE, Embase, Cochrane, CINAHL, and PsycINFO, combined PC, intensive care, and implementation terms.

RESULTS

84 studies (8 process evaluations, 76 effectiveness studies) were included. Published evidence on ICU-PC interventions is substantial, but reporting on implementation factors is variable and often lacking, especially for patient and family-related determinants and for all aspects of mechanisms. Main facilitators for implementation are adequate resources and collaboration between PC and ICU teams. Main barriers to implementation are lack of resources, negative perceptions of PC, and high ICU acuity. Implementation strategies include auditing resources, building stakeholder collaboratives, creating adaptable interventions, utilising champions, and supporting education. Mechanisms most commonly worked by facilitating collaborative working.

CONCLUSION

This review provides recommendations for ICUs when designing (stakeholder involvement, ICU-PC collaboration, assessment of culture and resources); implementing (targeted and adapted strategies, champions, and education); and evaluating/reporting (collect effectiveness and implementation data, including mechanisms) ICU-PC interventions. Use of implementation structures and patient/family involvement are both needed and important to be included.

Assessing palliative care practices in intensive care units and interpreting them using the lens of appropriate care concepts. An umbrella review

PURPOSE

Intensive care units (ICUs) have significant palliative care needs but lack a reliable care framework. This umbrella review addresses them by synthesising palliative care practices provided at end-of-life to critically ill patients and their families before, during, and after ICU admission.

METHODS

Seven databases were systematically searched for systematic reviews, and the umbrella review was conducted according to the guidelines laid out by the Joanna Briggs Institute (JBI).

RESULTS

Out of 3122 initial records identified, 40 systematic reviews were included in the synthesis. Six key themes were generated that reflect the palliative and end-of-life care practices in the ICUs and their outcomes. Effective communication and accurate prognostications enabled families to make informed decisions, cope with uncertainty, ease distress, and shorten ICU stays. Inter-team discussions and agreement on a plan are essential before discussing care goals. Recording care preferences prevents unnecessary end-of-life treatments. Exceptional end-of-life care should include symptom management, family support, hydration and nutrition optimisation, avoidance of unhelpful treatments, and bereavement support. Evaluating end-of-life care quality is critical and can be accomplished by seeking family feedback or conducting a survey.

CONCLUSION

This umbrella review encapsulates current palliative care practices in ICUs, influencing patient and family outcomes and providing insights into developing an appropriate care framework for critically ill patients needing end-of-life care and their families.

Health-related quality of life and participation after inpatient rehabilitation of sepsis survivors with severe sequelae: a cohort study

OBJECTIVE

To describe health-related quality of life and participation after rehabilitation of severely affected sepsis survivors.

DESIGN

Cohort study.

SUBJECTS/PATIENTS

Patients with severe sequelae after sepsis treated in a multidisciplinary rehabilitation pathway were included.

METHODS

Patient characteristics at the time of diagnosis, and the outcome 3 months after discharge from rehabilitation are described. At that time, health-related quality of life, social participation, and the rate of living at home were measured.

RESULTS

Of the 498 patients enrolled, 100 severely impaired patients were transferred for a multidisciplinary rehabilitation approach. Fifty-five of them were followed up at 3 months. Descriptive and inference statistics showed that 69% were living at home with or without care. Health-related quality of life and participation scores were 0.64 ± 0.32 for the EQ-5D utility index and 54.98 ± 24.97 for the Reintegration of Normal Living Index. A multivariate regression model explaining health-related quality of life at 3 months included age, lower limb strength, and walking ability during rehabilitation (r2 = 0.5511). Participation at 3 months was explained by age, body mass index, lower limb strength, and duration of tracheal intubation (r2 = 0.6229).

CONCLUSION

Patients who have experienced serious sepsis with severe sequelae can achieve a moderate level of quality of life and participation within a multidisciplinary pathway.

An update of palliative care in lung transplantation with a focus on symptoms, quality of life and functional outcomes

PURPOSE OF REVIEW

Palliative care (PC) in lung transplantation is increasingly acknowledged for its important role in addressing symptoms, enhancing functionality, and facilitating advance care planning for patients, families, and caregivers. The present review provides an update in PC management in lung transplantation.

RECENT FINDINGS

Research confirms the effectiveness of PC for patients with advanced lung disease who are undergoing transplantation, showing improvements in symptoms and reduced healthcare utilization. Assessment tools and patient-reported outcome measures for PC are commonly used in lung transplant candidates, revealing discrepancies between symptom severity and objective measures such as exercise capacity. The use of opioids to manage dyspnea and cough in the pretransplant period is deemed safe and does not heighten risks posttransplantation. However, the integration of PC support in managing symptoms and chronic allograft dysfunction in the posttransplant period has not been as well described.

SUMMARY

Palliative care support should be provided in the pretransplant and select peri-operative and posttransplant periods to help support patient quality of life, symptoms, communication and daily function.

Palliative Care Utilization and Hospital Transfers in Veterans Treated in Telecritical Care-Supported Intensive Care Units Versus Non-Telecritical Care Intensive Care Units

Background: Although telecritical care (TCC) implementation is associated with reduced mortality and interhospital transfer rates, its impact on goal-concordant care delivery in critical illness is unknown. We hypothesized that implementation of TCC across the Veterans' Health Administration system resulted in increased palliative care consultation and goals of care evaluation, yielding reduced transfer rates. Methods: We included veterans admitted to intensive care units between 2008 and 2022. We compared palliative care consultation and transfer rates before and after TCC implementation with rates in facilities that never implemented TCC. We used generalized linear mixed multivariable models to assess the associations between TCC initiation, palliative care consultation, and transfer and subsequently used mediation analysis to evaluate potential causality in this relationship. Results: Overall, 1,020,901 veterans met inclusion criteria. Demographic characteristics of patients were largely comparable across groups, although TCC facilities served more rural veterans. Palliative care consultation rates increased substantially in both ever-TCC and never-TCC hospitals during the study period (2.3%-4.3%, and 1.6%-4.7%, p < 0.01). Admissions post-TCC implementation were associated with an increased likelihood of palliative care consultation (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.01-1.15). TCC implementation was also associated with a reduction in transfer rates (OR 0.90, 95% CI 0.84-0.95). Mediation analysis did not demonstrate a causal relationship between TCC implementation, palliative care consultation, and reductions in interhospital transfer rate. Conclusions: TCC is associated with increased palliative care engagement, while TCC and palliative care engagement are both independently related to reduced transfers.

An Evolutionary Concept Analysis of the "Fighter" in the Intensive Care Unit

The purpose of this article was to analyze the concept of "the fighter in the intensive care unit (ICU)" per the scientific literature and the impact this mentality has on care administered in the ICU. A literature review and a concept analysis based on Rodger's evolutionary method were performed to identify surrogate terms, antecedents, attributes, and consequences pertaining to the "fighter" in the ICU. Thirteen articles with a focus on "the fighter" were included in this analysis. There is a strong desire to remain optimistic and maintain high spirits as a coping mechanism in the face of extreme prognostic uncertainty. Themes that emerged from the literature were the need to find inner strength and persist in the face of adversity. The concept of "the fighter in the ICU" can serve as either adaptive or maladaptive coping, depending on the larger clinical picture. Patient experiences in the ICU are fraught with physical and psychological distress. How the patient and family unit cope during this anxiety-provoking time is based on the individual. Maintaining optimism and identifying as a fighter can be healthy ways to adapt to the circumstances. This concept analysis highlights the importance of holistic care and instilling hope particularly as patients may be nearing the end of life.

Intensive Care Unit Nurses' Attitudes Toward Truth-Telling, Life-Sustaining Treatment, and Decision-Making Intention for End-of-Life Patients: A Cross-sectional Survey

Truth-telling and life-sustaining treatment decisions are important elements of the quality of patients' care at the end of life. As the primary caregivers of patients at the end of life in intensive care units (ICUs), ICU nurses play an important role in patient decision making and hospice care. This study aimed to investigate and analyze ICU nurses' attitudes toward truth-telling, attitudes toward end-of-life life-sustaining treatment, and end-of-life decision-making behavioral intentions. One hundred twenty-two ICU nurses participated in this cross-sectional survey. Data were collected using a validated questionnaire. The results showed that ICU nurses' attitudes toward telling patients the truth and end-of-life life-sustaining treatment were both positive, but further improvement is needed. Nurses have a higher willingness to make palliative care decisions for patients at the end of life and to help patients achieve a good death. The truth-telling attitude, the life-sustaining treatment attitude, and whether they knew that cardiopulmonary resuscitation could be legally forgone at the end of life were factors influencing ICU nurses' behavioral intention toward decision making for patients at the end of life (all P s < .05). We conclude that nurses' participation in truth-telling and end-of-life decision making should be promoted, and timely hospice care should be provided to patients to help them achieve a good death.

Venoarterial extracorporeal membrane oxygenation in immunocompromised patients with cardiogenic shock: a cohort study and propensity-weighted analysis

PURPOSE

The outcomes of immunocompromised patients with cardiogenic shock treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) are seldom documented, making ECMO candidacy decisions challenging. This study aims (1) to report outcomes of immunocompromised patients treated with VA-ECMO, (2) to identify pre-ECMO predictors of 90-day mortality, (3) to assess the impact of immunodepression on 90-day mortality, and (4) to describe the main ECMO-related complications.

METHODS

This is a retrospective, propensity-weighted study conducted in two French experienced ECMO centers.

RESULTS

From January 2006 to January 2022, 177 critically ill immunocompromised patients (median (interquartile range, IQR) age 49 (32-60) years) received VA-ECMO. The main causes of immunosuppression were long-term corticosteroids/immunosuppressant treatment (29%), hematological malignancy (26%), solid organ transplant (20%), and solid tumor (13%). Overall 90-day and 1-year mortality were 70% (95% confidence interval (CI) 63-77%) and 75% (95% CI 65-79%), respectively. Older age and higher pre-ECMO lactate were independently associated with 90-day mortality. Across immunodepression causes, 1-year mortality ranged from 58% for patients with infection by human immunodeficiency virus (HIV) or asplenia, to 89% for solid organ transplant recipients. Hemorrhagic and infectious complications affected 39% and 54% of patients, while more than half the stay in intensive care unit (ICU) was spent on antibiotics. In a propensity score-weighted model comparing the 177 patients with 942 non-immunocompromised patients experiencing cardiogenic shock on VA-ECMO, immunocompromised status was independently associated with a higher 90-day mortality (odds ratio 2.53, 95% CI 1.72-3.79).

CONCLUSION

Immunocompromised patients undergoing VA-ECMO treatment face an unfavorable prognosis, with higher 90-day mortality compared to non-immunocompromised patients. This underscores the necessity for thorough evaluation and careful selection of ECMO candidates within this frail population.

Factors associated with healthcare providers' satisfaction with end-of-life care in the intensive care unit: A systematic review

BACKGROUND

We aimed to synthesize published data on and identify factors associated with healthcare providers' satisfaction with end-of-life care for critically ill adults.

METHODS

Electronic databases were searched from inception to January 23, 2023. We included trials involving adults admitted to intensive care units (ICUs) or high-dependency units to evaluate palliative care interventions.

STUDY SELECTION

The inclusion criteria were as follows: 1) Adult patients (age ≥18 years) or their family members admitted to the ICU or a high-dependency unit; 2) ICU palliative care interventions; 3) Randomized and non-randomized controlled trials; and 4) Full-text, peer-reviewed articles published in English. Two reviewers screened and extracted the data and assessed bias risk. The primary outcome was an improvement in the healthcare providers' satisfaction based on the validated scales.

RESULTS

Out of 12 studies, 9 investigated combined dimension intervention. Healthcare providers' satisfaction improved in 6/7 (85.7%) of the studies testing educational intervention, 5/7 (71.4%) studies testing the effectiveness of palliative care team involvement, 4/5 (80%) of studies testing communication interventions, while 0/2 (0%) study testing ethic consultations.

CONCLUSIONS

Most of the tested palliative care interventions were associated with improved healthcare provider satisfaction in intensive care units. The impacts of such intervention on mental health and burden remain to be investigated in this field.

Ethisch begründet entscheiden in der Intensivmedizin

The process recommendations of the Ethics Section of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) for ethically based decision-making in intensive care medicine are intended to create the framework for a structured procedure for seriously ill patients in intensive care. The processes require appropriate structures, e.g., for effective communication within the treatment team, with patients and relatives, legal representatives, as well as the availability of palliative medical expertise, ethical advisory committees and integrated psychosocial and spiritual care services. If the necessary competences and structures are not available in a facility, they can be consulted externally or by telemedicine if necessary. The present recommendations are based on an expert consensus and are not the result of a systematic review or a meta-analysis.

[Palliative aspects in clinical acute and emergency medicine as well as intensive care medicine : Consensus paper of the DGIIN, DGK, DGP, DGHO, DGfN, DGNI, DGG, DGAI, DGINA and DG Palliativmedizin]

The integration of palliative medicine is an important component in the treatment of various advanced diseases. While a German S3 guideline on palliative medicine exists for patients with incurable cancer, a recommendation for non-oncological patients and especially for palliative patients presenting in the emergency department or intensive care unit is missing to date. Based on the present consensus paper, the palliative care aspects of the respective medical disciplines are addressed. The timely integration of palliative care aims to improve quality of life and symptom control in clinical acute and emergency medicine as well as intensive care.

Integrating Palliative Care into Burn Care: A Retrospective Application of Criteria for Appropriate Referral

Burn injuries often require complex interdisciplinary care. Despite potential benefits, consultation with specialist palliative care typically occurs in 2% of burn admissions, due largely to lack of availability and misconceptions concerning palliative care. Criteria to guide consultation with specialist palliative care have been developed at this institution. The purpose of this study was to quantify the sensitivity and specificity of these criteria, and then optimize them. Retrospective examination of 388 admissions over 15 months at this adult and pediatric Burn Center were conducted. Chi-square or Fisher's exact test for categorical variables and Wilcoxon Rank Sum test for continuous variables were used to test for between-group differences in demographic and clinical characteristics. Logistic regression model was built to determine modified Baux cut-off score using Youden index (J) value. Criteria were sensitive (0.96) and specific (0.90), though with a low positive predictive value (0.43). Persons with lengths of stay greater than one week, advanced directives, Allow Natural Death orders, and/or deterioration events were significantly more likely to have had palliative care consulted. There were significant between-group differences (with/without palliative care consultation) based on burn surface area, modified Baux score, and mortality risk. Potential criteria revisions are proposed. Prospective adherence to revised criteria could provide useful guidance to providers and benefit to patients and families.

Early Integrated Palliative Care Within a Surgical Oncology Clinic

Importance

Advance directive (AD) designation is an important component of advance care planning (ACP) that helps align care with patient goals. However, it is underutilized in high-risk surgical patients with cancer, and multiple barriers contribute to the low AD designation rates in this population.

Objective

To assess the association of early palliative care integration with changes in AD designation among patients with cancer who underwent surgery.

Design, Setting, and Participants

This cohort study was a retrospective analysis of a prospectively maintained registry of adult patients who underwent elective surgery for advanced abdominal and soft tissue malignant tumors at a surgical oncology clinic in a comprehensive cancer center with expertise in regional therapeutics between June 2016 and May 2022, with a median (IQR) postoperative follow-up duration of 27 (15-43) months. Data analysis was conducted from December 2022 to April 2023.

Exposure

Integration of ACP recommendations and early palliative care consultations into the surgical workflow in 2020 using electronic health records (EHR), preoperative checklists, and resident education.

Main Outcomes and Measures

The primary outcomes were AD designation and documentation. Multivariable logistic regression was performed to assess factors associated with AD designation and documentation.

Results

Among the 326 patients (median [IQR] age 59 [51-67] years; 189 female patients [58.0%]; 243 non-Hispanic White patients [77.9%]) who underwent surgery, 254 patients (77.9%) designated ADs. The designation rate increased from 72.0% (131 of 182 patients) before workflow integration to 85.4% (123 of 144 patients) after workflow integration in 2020 (P = .004). The AD documentation rate did not increase significantly after workflow integration in 2020 (48.9% [89 of 182] ADs documented vs 56.3% [81 of 144] ADs documented; P = .19). AD designation was associated with palliative care consultation (odds ratio [OR], 41.48; 95% CI, 9.59-179.43; P < .001), palliative-intent treatment (OR, 5.12; 95% CI, 1.32-19.89; P = .02), highest age quartile (OR, 3.79; 95% CI, 1.32-10.89; P = .01), and workflow integration (OR, 2.05; 95% CI, 1.01-4.18; P = .048). Patients who self-identified as a race or ethnicity other than non-Hispanic White were less likely to have designated ADs (OR, 0.36; 95% CI, 0.17-0.76; P = .008). AD documentation was associated with palliative care consulation (OR, 4.17; 95% CI, 2.57- 6.77; P < .001) and the highest age quartile (OR, 2.41; 95% CI, 1.21-4.79; P = .01).

Conclusions and Relevance

An integrated ACP initiative was associated with increased AD designation rates among patients with advanced cancer who underwent surgery. These findings demonstrate the feasibility and importance of modifying clinical pathways, integrating EHR-based interventions, and cohabiting palliative care physicians in the surgical workflow for patients with advanced care.

[Advanced care planing and end of life decisions - the geriatricians' view]

Medical progress and the increasing desire for self-determination, even in the most difficult life situations, as well as the associated increasing possibilities of influencing life and dying lead to possibilities but also obligations for individual treatment design. Especially at the end of life, the desire for provision is great and many decisions need to be made in advance or by proxy. In daily dealings with sick or seriously ill people at the end of their lives, it is very helpful if appropriate advance directives have been made and the patient's wishes can be implemented simply and clearly. With the possibility of advance planning for the end of life (Advance Care Planning (ACP)), there is a precautionary and planning concept that will hopefully be used more and more in the future.

Supporting families of patients who die in adult intensive care: A scoping review of interventions

BACKGROUND

Families who perceive themselves as prepared for an impending death experience reduced psychological burden during bereavement. Understanding which interventions promote death preparedness in families during end-of-life care in intensive care will inform future intervention development and may help limit the burden of psychological symptoms associated with bereavement.

AIM

To identify and characterise interventions that help prepare families for the possibility of death in intensive care, incorporating barriers to intervention implementation, outcome variables and instruments used.

DESIGN

Scoping review using Joanna Briggs methodology, prospectively registered and reported using relevant guidelines.

DATA SOURCES

A systematic search of six databases from 2007 to 2023 for randomised controlled trials evaluating interventions that prepared families of intensive care patients for the possibility of death. Citations were screened against the inclusion criteria and extracted by two reviewers independently.

RESULTS

Seven trials met eligibility criteria. Interventions were classified: decision support, psychoeducation, information provision. Psychoeducation involving physician-led family conference, emotional support and written information reduced symptoms of anxiety, depression, prolonged grief, and post-traumatic stress in families during bereavement. Anxiety, depression, and post-traumatic stress were assessed most frequently. Barriers and facilitators to intervention implementation were seldom reported.

CONCLUSION

This review provides a conceptual framework of interventions to prepare families for death in intensive care, while highlighting a gap in rigorously conducted empirical research in this area. Future research should focus on theoretically informed, family-clinician communication, and explore the benefits of integrating existing multidisciplinary palliative care guidelines to deliver family conference within intensive care.

IMPLICATIONS FOR CLINICAL PRACTICE

Intensive care clinicians should consider innovative communication strategies to build family-clinician connectedness in remote pandemic conditions. To prepare families for an impending death, mnemonic guided physician-led family conference and printed information could be implemented to prepare families for death, dying and bereavement. Mnemonic guided emotional support during dying and family conference after death may also assist families seeking closure.

Recommendations on palliative care aspects in intensive care medicine

BACKGROUND

The timely integration of palliative care is important for patients suffering from various advanced diseases with limited prognosis. While a German S-3-guideline on palliative care exists for patients with incurable cancer, a recommendation for non-oncological patients and especially for integration of palliative care into intensive care medicine is missing to date.

METHOD

Ten German medical societies worked on recommendations on palliative care aspects in intensive care in a consensus process from 2018 to 2023.

RESULTS

Based on the german consensus paper, the palliative care aspects of the respective medical disciplines concerning intensive care are addressed. The recommendations partly refer to general situations, but also to specific aspects or diseases, such as geriatric issues, heart or lung diseases, encephalopathies and delirium, terminal renal diseases, oncological diseases and palliative emergencies in intensive care medicine. Measures such as non-invasive ventilation for symptom control and compassionate weaning are also included.

CONCLUSION

The timely integration of palliative care into intensive care medicine aims to improve quality of life and symptom control and also takes into acccount the often urgently needed support for patients' highly stressed relatives.

Does Hospitalist Care Enhance Palliative Care and Reduce Aggressive Treatments for Terminally Ill Patients? A Propensity Score-Matched Study

BACKGROUND

Information on the use of palliative care and aggressive treatments for terminally ill patients who receive care from hospitalists is limited.

METHODS

This three-year, retrospective, case-control study was conducted at an academic medical center in Taiwan. Among 7037 patients who died in the hospital, 41.7% had a primary diagnosis of cancer. A total of 815 deceased patients who received hospitalist care before death were compared with 3260 patients who received non-hospitalist care after matching for age, gender, catastrophic illness, and Charlson comorbidity score. Regression models with generalized estimating equations were performed.

RESULTS

Patients who received hospitalist care before death, compared to those who did not, had a higher probability of palliative care consultation (odds ratio (OR) = 3.41, 95% confidence interval (CI): 2.63-4.41), and a lower probability to undergo invasive mechanical ventilation (OR = 0.13, 95% CI: 0.10-0.17), tracheostomy (OR = 0.14, 95% CI: 0.06-0.31), hemodialysis (OR = 0.70, 95% CI: 0.55-0.89), surgery (OR = 0.25, 95% CI: 0.19-0.31), and intensive care unit admission (OR = 0.11, 95% CI: 0.08-0.14). Hospitalist care was associated with reductions in length of stay (coefficient (B) = -0.54, 95% CI: -0.62--0.46) and daily medical costs.

CONCLUSIONS

Hospitalist care is associated with an improved palliative consultation rate and reduced life-sustaining treatments before death.

Enhancing end of life care on general internal medical wards: the 3 Wishes Project

BACKGROUND

Initially developed in the intensive care unit (ICU) at St. Joseph's Healthcare Hamilton (SJHH) the 3 Wishes Project (3WP) provides personalized, compassionate care to dying patients and their families. The objective of this study was to develop and evaluate 3WP expansion strategies for patients cared for on General Internal Medicine (GIM) wards in our hospital.

METHODS

From January 2020-November 2021, we developed a phased, multicomponent approach for program expansion. We enrolled patients on the GIM wards who had a high probability of dying in hospital, then elicited, implemented, and documented wishes for them or their families. Data were analyzed descriptively.

RESULTS

From March 2020 to November 2020, we implemented staff education and engagement activities, created an Expansion Coordinator position, held strategic consultations, and offered enabling resources. From March 2020 to November 2021, we enrolled 62 patients and elicited 281 wishes (median [1^st, 3^rd quartiles] 4 [4, 5] wishes/patient). The most common wish categories were personalizing the environment (67 wishes, 24%), rituals and spiritual support (42 wishes, 15%), and facilitating connections (39 wishes, 14%). The median [1^st, 3^rd] cost/patient was $0 [0, $10.00] (range $0 to $86); 91% of wishes incurred no cost to the program.

CONCLUSIONS

The formal expansion of the 3WP on GIM wards has been successful despite COVID-19 pandemic disruptions. While there is still work ahead, these data suggest that implementing the 3WP on the GIM wards is feasible and affordable. Increased engagement of the clinical team during the pandemic suggests that it is positively received.

Stakeholder engagement as a strategy to enhance palliative care involvement in intensive care units: A theory of change approach

BACKGROUND

Adult patients admitted to intensive care units in the terminal phase experience high symptom burden, increased costs, and diminished quality of dying. There is limited literature on palliative care engagement in ICU, especially in lower-middle-income countries. This study explores a strategy to enhance palliative care engagement in ICU through a stakeholder participatory approach.

METHODS

Theory of Change approach was used to develop a hypothetical causal pathway for palliative care integration into ICUs in India. Four facilitated workshops and fifteen research team meetings were conducted virtually over three months. Thirteen stakeholders were purposively chosen, and three facilitators conducted the workshops. Data included workshop discussion transcripts, online chat box comments, and team meeting minutes. These were collected, analysed and represented as theory of change map.

RESULTS

The desired impact of palliative care integration was good death. Potential long-term outcomes identified were fewer deaths in ICUs, discharge against medical advice, and inappropriate admissions; increased referrals to palliative care; and improved patient and family satisfaction. Twelve preconditions were identified, and eleven key interventions were developed. Five overarching assumptions related to contextual factors influencing the outcomes of interventions.

CONCLUSION

Theory of change framework facilitated the identification of proposed mechanisms and interventions underpinning palliative care integration in ICUs.

The 3 Wishes Program Improves Families' Experience of Emotional and Spiritual Support at the End of Life

BACKGROUND

The end-of-life (EOL) experience in the intensive care unit (ICU) is emotionally challenging, and there are opportunities for improvement. The 3 Wishes Program (3WP) promotes the dignity of dying patients and their families by eliciting and implementing wishes at the EOL.

AIM

To assess whether the 3WP is associated with improved ratings of EOL care.

PROGRAM DESCRIPTION

In the 3WP, clinicians elicit and fulfill simple wishes for dying patients and their families.

SETTING

2-hospital academic healthcare system.

PARTICIPANTS

Dying patients in the ICU and their families.

PROGRAM EVALUATION

A modified Bereaved Family Survey (BFS), a validated tool for measuring EOL care quality, was completed by families of ICU decedents approximately 3 months after death. We compared patients whose care involved the 3WP to those who did not using three BFS-derived measures: Respectful Care and Communication (5 questions), Emotional and Spiritual Support (3 questions), and the BFS-Performance Measure (BFS-PM, a single-item global measure of care).

RESULTS

Of 314 completed surveys, 117 were for patients whose care included the 3WP. Bereaved families of 3WP patients rated the Emotional and Spiritual Support factor significantly higher (7.5 vs. 6.0, p = 0.003, adjusted p = 0.001) than those who did not receive the 3WP. The Respectful Care and Communication factor and BFS-PM were no different between groups.

DISCUSSION

The 3WP is a low-cost intervention that may be a feasible strategy for improving the EOL experience.

Barriers and facilitators in the provision of palliative care in adult intensive care units: a scoping review

The provision of palliative care in the intensive care unit (ICU) is increasing. While some scholars have suggested the goals of palliative care to not be aligned with the ICU, some evidence show benefits of the integration. This review aimed to explore and synthesize research that identified barriers and facilitators in the provision of palliative care in the ICU. This review utilized Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review guidelines based on population, concept, and context. We searched for eligible studies in five electronic databases (Scopus, PubMed, ProQuest, Science Direct, and Sage) and included studies on the provision of palliative care (concept) in the ICU (context) that were published in English between 2005-2021. We describe the provision of palliative care in terms of barriers and facilitators. We also describe the study design and context. A total of 14 papers was included. Several barriers and facilitators in providing palliative care in the ICU were identified and include lack of capabilities, family boundaries, practical issues, cultural differences. Facilitators of the provision of palliative care in an ICU include greater experience and supportive behaviors, i.e., collaborations between health care professionals. This scoping review demonstrates the breadth of barriers and facilitators of palliative care in the ICU. Hospital management can consider findings of the current review to better integrate palliative care in the ICU.

Palliative and end-of-life care in intensive care units in low- and middle-income countries: A systematically constructed scoping review

PURPOSE

Death is common in intensive care units, and integrating palliative care enhances outcomes. Most research has been conducted in high-income countries. The aim is to understand what is known about the type and topics of research on the provision of palliative care within intensive care units in low- and middle-income countries MATERIALS AND METHODS: Scoping review with nine databases systematically searched for literature published in English on palliative care in intensive care units in low- and middle- income settings (01/01/1990 to 31/05/2021). Two reviewers independently checked search results and extracted textual data, which were analyzed and represented as themes.

RESULTS

Thirty papers reported 19 empirical studies, two clinical case reports and six discussion papers. Papers originated from Asia and Africa, primarily using observational designs and qualitative approaches, with no trials or other robust evaluative or comparative studies. No studies directly sought data from patients or families. Five areas of research focus were identified: withholding and withdrawing treatment; professional knowledge and skills; patient and family views; culture and context; and costs of care.

CONCLUSIONS

Palliative care in intensive care units in low-and middle-income countries is understudied. Research focused on the specific needs of intensive care in low- and middle-income countries is required to ensure optimal patient outcomes.

Implementation lessons learnt when trialling palliative care interventions in the intensive care unit: relationships between determinants, implementation strategies, and models of delivery-a systematic review protocol

BACKGROUND

Heterogeneity amongst palliative care interventions in the intensive care unit (ICU) and their outcomes has meant that, even when found to be effective, translation of evidence into practice is hindered. Previous evidence reviews have suggested that the field of ICU-based palliative care would benefit from well-designed, targeted interventions, with explicit knowledge translation research demonstrating valid implementation strategies. Reviewing effectiveness studies alongside process evaluations for these interventions will give insight into the implementation barriers or constraints identified, and the implementation strategies adopted.

METHODS

A systematic review to identify and synthesise knowledge on how models of integrating palliative care into the ICU have been implemented and provide critical recommendations for successful future development and implementation of complex interventions in the field. The search will be carried out using MEDLINE, Embase, Cochrane, CINAHL, and PsycINFO. The search strategy will combine terms related to palliative care, intensive care, and implementation. Only full-text articles will be considered and conference abstracts excluded. There will be no date or language restrictions. The Implementation Research Logic Model will be used as a framework for synthesis. Findings will be reported following the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

DISCUSSION

This review will provide understanding of implementation facilitators, barriers, and strategies, when employing palliative care interventions within the ICU. This will provide valuable recommendations for successful future development of complex interventions using implementation frameworks or theories. This can increase the potential for sustained change in practice, reduce heterogeneity in interventions, and therefore help produce measurable and comparable outcomes.

Collaboration between nurses and doctors in the decision-making process when considering ending the life-prolonging treatment of intensive care patients

AIMS

The aim of the study was to explore intensive care nurses' collaboration with doctors' when considering ending the life-prolonging treatment of patients in the intensive care unit.

DESIGN

A qualitative method with an explorative descriptive design was employed.

METHODS

Data were collected through semi-structured interviews with four intensive care nurses and four doctors working in three intensive care units at two university hospitals and one local hospital. The data were analysed using systematic text condensation. This study was reported according to the consolidated criteria for reporting qualitative research checklist.

RESULTS

Two categories were identified in the data analysis: listening to each other during the decision-making process and continuity and having time to facilitate regular discussions of prognosis and treatment plans.

ProPACC: Protocol for a Trial of Integrated Specialty Palliative Care for Critically Ill Older Adults

BACKGROUND

Each year, approximately one million older adults die in American intensive care units (ICUs) or survive with significant functional impairment. Inadequate symptom management, surrogates' psychological distress and inappropriate healthcare use are major concerns. Pioneering work by Dr. J. Randall Curtis paved the way for integrating palliative care (PC) specialists to address these needs, but convincing proof of efficacy has not yet been demonstrated.

DESIGN

We will conduct a multicenter patient-randomized efficacy trial of integrated specialty PC (SPC) vs. usual care for 500 high-risk ICU patients over age 60 and their surrogate decision-makers from five hospitals in Pennsylvania.

INTERVENTION

The intervention will follow recommended best practices for inpatient PC consultation. Patients will receive care from a multidisciplinary SPC team within 24 hours of enrollment that continues until hospital discharge or death. SPC clinicians will meet with patients, families, and the ICU team every weekday. SPC and ICU clinicians will jointly participate in proactive family meetings according to a predefined schedule. Patients in the control arm will receive routine ICU care.

OUTCOMES

Our primary outcome is patient-centeredness of care, measured using the modified Patient Perceived Patient-Centeredness of Care scale. Secondary outcomes include surrogates' psychological symptom burden and health resource utilization. Other outcomes include patient survival, as well as interprofessional collaboration. We will also conduct prespecified subgroup analyses using variables such as PC needs, measured by the Needs of Social Nature, Existential Concerns, Symptoms, and Therapeutic Interaction scale.

CONCLUSIONS

This trial will provide robust evidence about the impact of integrating SPC with critical care on patient, family, and health system outcomes.

Primary palliative care recommendations for critical care clinicians

Palliative care is an interdisciplinary care to optimize physical, psychosocial, and spiritual symptoms of patients and their families whose quality of life is impaired by serious, life-limiting illness. In 2021, the importance of providing palliative care in the intensive care unit (ICU) is well recognized by various studies to alleviate physical symptoms due to invasive treatments, to set patient-centered goals of care, and to provide end-of-life care. This paper summarizes the evidence known to date on primary palliative care delivered in the ICU settings. We will then discuss the potential benefits and harms of primary palliative care so that critical care clinicians are better equipped to decide what services might best improve the palliative care needs in their ICUs.

Derivation and performance of an end-of-life practice score aimed at interpreting worldwide treatment-limiting decisions in the critically ill

Background

Limitations of life-sustaining interventions in intensive care units (ICUs) exhibit substantial changes over time, and large, contemporary variation across world regions. We sought to determine whether a weighted end-of-life practice score can explain a large, contemporary, worldwide variation in limitation decisions.

Methods

The 2015–2016 (Ethicus-2) vs. 1999–2000 (Ethicus-1) comparison study was a two-period, prospective observational study assessing the frequency of limitation decisions in 4952 patients from 22 European ICUs. The worldwide Ethicus-2 study was a single-period prospective observational study assessing the frequency of limitation decisions in 12,200 patients from 199 ICUs situated in 8 world regions. Binary end-of-life practice variable data (1 = presence; 0 = absence) were collected post hoc (comparison study, 22/22 ICUs, n = 4592; worldwide study, 186/199 ICUs, n = 11,574) for family meetings, daily deliberation for appropriate level of care, end-of-life discussions during weekly meetings, written triggers for limitations, written ICU end-of-life guidelines and protocols, palliative care and ethics consultations, ICU-staff taking communication or bioethics courses, and national end-of-life guidelines and legislation. Regarding the comparison study, generalized estimating equations (GEE) analysis was used to determine associations between the 12 end-of-life practice variables and treatment limitations. The weighted end-of-life practice score was then calculated using GEE-derived coefficients of the end-of-life practice variables. Subsequently, the weighted end-of-life practice score was validated in GEE analysis using the worldwide study dataset.

Results

In comparison study GEE analyses, end-of-life discussions during weekly meetings [odds ratio (OR) 0.55, 95% confidence interval (CI) 0.30–0.99], end-of-life guidelines [OR 0.52, (0.31–0.87)] and protocols [OR 15.08, (3.88–58.59)], palliative care consultations [OR 2.63, (1.23–5.60)] and end-of-life legislation [OR 3.24, 1.60–6.55)] were significantly associated with limitation decisions (all P < 0.05). In worldwide GEE analyses, the weighted end-of-life practice score was significantly associated with limitation decisions [OR 1.12 (1.03–1.22); P = 0.008].

Conclusions

Comparison study-derived, weighted end-of-life practice score partly explained the worldwide study’s variation in treatment limitations. The most important components of the weighted end-of-life practice score were ICU end-of-life protocols, palliative care consultations, and country end-of-life legislation.
