End-of-life issues in critically ill cancer patients

Evidence Guiding Withdrawal of Mechanical Ventilation at the End of Life: A Review

OBJECTIVE

Distress at the end of life in the intensive care unit (ICU) is common. We reviewed the evidence guiding symptom assessment, withdrawal of mechanical ventilation (WMV) process, support for the ICU team, and symptom management among adults, and specifically older adults, at end of life in the ICU.

SETTING AND DESIGN

Systematic search of published literature (January 1990-December 2021) pertaining to WMV at end of life among adults in the ICU setting using PubMed, Embase, and Web of Science. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed.

PARTICIPANTS

Adults (age 18 and over) undergoing WMV in the ICU.

MEASUREMENTS

Study quality was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

Out of 574 articles screened, 130 underwent full text review, and 74 were reviewed and assessed for quality. The highest quality studies pertained to use of validated symptom scales during WMV. Studies of the WMV process itself were generally lower quality. Support for the ICU team best occurs via structured communication and social supports. Dyspnea is the most distressing symptom, and while high quality evidence supports the use of opiates, there is limited evidence to guide implementation of their use for specific patients.

CONCLUSION

High quality studies support some practices in palliative WMV, while gaps in evidence remain for the WMV process, supporting the ICU team, and medical management of distress. Future studies should rigorously compare WMV processes and symptom management to reduce distress at end of life.

Gynecologic oncology patient perspectives and knowledge on advance care planning: A quality improvement intervention

•

Gynecologic oncology patients prefer advance care planning (ACP) communication outpatient with their gynecologic oncologist.

•

A quality improvement intervention offering advance care planning resources increased ACP discussions.

•

A quality improvement intervention offering advance care planning resources improved ACP document creation proficiency.

Objectives

Assess and improve advance care planning (ACP) awareness and uptake among gynecologic oncology patients.

Methods

Using a quality improvement Plan-Do-Check-Act framework, we completed a single institution needs assessment and intervention. The needs assessment was a 26-question survey assessing baseline ACP knowledge and preferences of gynecologic oncology patients. We used this survey to implement an outpatient intervention in which patients were offered ACP resources (pamphlet, discussion with their gynecologic oncologist, and/or social work referral). We conducted a post-intervention survey among patients who had and had not received ACP resource(s) to assess whether our intervention increased ACP knowledge, discussions, or uptake.

Results

Among 106 patients surveyed in the needs assessment, 33 % had ACP documents, 26 % had discussed ACP with a physician, and 82 % thought discussing ACP was important. The majority preferred these conversations in the outpatient setting (52 %) with their gynecologic oncologist (80 %) instead of nurses or trainees. In the intervention, 526 patients were offered ACP resources. Compared to women who did not receive resources (n = 324), patients who received ACP resource(s) (n = 202) were more likely to have ACP discussions with their gynecologic oncologist (38 % vs 68 %, P = 0.001) and had greater proficiency regarding how to create ACP documents (median score 5/10 vs 8/10, P = 0.048), although they were no more likely to have ACP documented in their electronic medical record (27 % vs 9 %, p = 0.08).

Conclusions

ACP uptake among gynecologic oncology patients is low, but ACP discussions with an oncologist during outpatient visits are important to patients and improve their knowledge regarding completing ACP documents.

Spiritual Care of Inpatients Focusing on Outcomes and the Role of Chaplaincy Services: A Systematic Review

OBJECTIVE

To identify demographic trends associated with patient utilization and healthcare provider request for spiritual care services and to describe the impact of spiritual care on the quality of life (QoL), spiritual well-being (SWB) and level of satisfaction (SAT) of hospitalized patients.

PATIENTS AND METHODS

A systematic search of Ovid MEDLINE, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, was combined with review of relevant bibliographies. A total of 464 titles and abstracts were reviewed. Data were independently extracted by reviewers according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data on the effects of spiritual interventions on QoL, SWB and SAT were extracted, along with demographic data reflecting chaplain services. The results of the studies are presented narratively and in a qualitative manner.

RESULTS

Observational or experimental studies investigating chaplain utilization demographics (n = 12), patient satisfaction (n = 9) and QoL/SWB (n = 3) were included. Perceived severity of illness, average length of stay and older age were consistently found to be predictors of higher need for spiritual care. Receipt of spiritual care was correlated with increased patient and family satisfaction, independent of clinical outcome. Chaplain interventions were associated with improvement in perceived QoL and SWB. In spite of this, healthcare workers rarely attempt to explore the patient's or family's need for spiritual care, with the majority of chaplaincy consults occurring in the final day of the patient's life, potentially leading to a failure to meet the spiritual needs of non-terminal patients who have spiritual trauma related to their resolving illnesses.

CONCLUSION

Attention to the spiritual needs of hospitalized patients is an essential yet often overlooked aspect of patient care. Chaplains serve as spiritual care specialists whose services can enhance the hospital experience, improve patient satisfaction and help to bridge potential gaps between the patient and medical providers.

How is life support withdrawn in intensive care units: A narrative review

PURPOSE

Decisions to withdraw life-sustaining therapy (WDLS) are relatively common in intensive care units across Canada. As part of preliminary work to develop guidelines for WDLS, we performed a narrative review of the literature to identify published studies of WDLS.

MATERIALS AND METHODS

A search of MEDLINE and EMBASE databases was performed. The results were reviewed and only articles relevant to WDLS were included. Any references within these articles deemed to be relevant were subsequently included.

RESULTS

The initial search identified 3687 articles. A total of 100 articles of interest were identified from the initial search and a review of their references. The articles were primarily composed of observational data and expert opinion. The information from the literature was organized into 6 themes: preparation for WDLS, monitoring parameters, pharmacologic symptom management, withdrawing life-sustaining therapies, withdrawal of mechanical ventilation, and bereavement.

CONCLUSIONS

This review describes current practices and opinions about WDLS, and also demonstrates the significant practice variation that currently exists. We believe that the development of guidelines to help increase transparency and standardize the process will be an important step to ensuring high quality care during WDLS.

"The Patient Is Dying, Please Call the Chaplain": The Activities of Chaplains in One Medical Center's Intensive Care Units

CONTEXT

Patients and families commonly experience spiritual stress during an intensive care unit (ICU) admission. Although most patients report that they want spiritual support, little is known about how these issues are addressed by hospital chaplains.

OBJECTIVES

To describe the prevalence, timing, and nature of hospital chaplain encounters in ICUs.

METHODS

This was a retrospective cross-sectional study of adult ICUs at an academic medical center. Measures included days from ICU admission to initial chaplain visit, days from chaplain visit to ICU death or discharge, hospital and ICU lengths of stay, severity of illness at ICU admission and chaplain visit, and chart documentation of chaplain communication with the ICU team.

RESULTS

Of a total of 4169 ICU admissions over six months, 248 (5.9%) patients were seen by chaplains. Of the 246 patients who died in an ICU, 197 (80%) were seen by a chaplain. There was a median of two days from ICU admission to chaplain encounter and a median of one day from chaplain encounter to ICU discharge or death. Chaplains communicated with nurses after 141 encounters (56.9%) but with physicians after only 14 encounters (5.6%); there was no documented communication in 55 encounters (22%).

CONCLUSION

In the ICUs at this tertiary medical center, chaplain visits are uncommon and generally occur just before death among ICU patients. Communication between chaplains and physicians is rare. Chaplaincy service is primarily reserved for dying patients and their family members rather than providing proactive spiritual support. These observations highlight the need to better understand challenges and barriers to optimal chaplain involvement in ICU patient care.

Investigational tests and treatments performed in terminal stage cancer patients in two weeks before death: Turkish oncology group (TOG) study

Although more palliative care is necessary for terminally ill cancer patients, excess investigational tests, invasive procedures, and treatments are given instead. Between November 2009 and December 2013, six hundred and twenty-four patients with end-stage cancer who were died at inpatient setting evaluated retrospectively. Patients' characteristics, sites of tumor and metastasis, tests and invasive procedures, treatments performed in the last 2 weeks before death were collected from the hospital files and analyzed. Median age of 624 patients was 58 (range 16-96) years. More than half of the patients (370, 59.3%) were men. The most frequent cancer sites were gastrointestinal (GI) system (32.2%), lung (24.0%), and breast (11.1%). Frequent metastatic sites were liver (34.8%), bone (31.5%), lung (23.3%), and/or brain (16.9%). Causes of death were respiratory failure, infections, and/or liver failure in 49.9, 23.9, and 19.4% of patients, respectively. Radiological tests performed in the last 2 weeks before death were ultrasonography, computed tomography, magnetic resonance imaging, bone scan in 25.6, 16.3, 11.4, and 3.8% of patients, respectively. Treatments received were intravenous (i.v) serum infusion, blood transfusion, total parenteral nutrition (TPN), human albumin infusion in 55.9, 44.1, 34.9, and 9.5% of patients, respectively. Invasive procedures such as invasive pain relief, terminal sedation, and chemotherapy performed in 12.6, 4.4, and 10.0% of patients, respectively. Central venous catheter application, paracentesis, thoracentesis, and GI endoscopy were applied in 41.7, 9.8, 5.6, and 3.4% of the patients, respectively. Radiological tests, invasive procedures, TPN, and human albumin transfusion were used excessively in terminal stage cancer patients in our medical oncology inpatient clinics. Invasive pain relief and terminal sedation were still underused in our cancer clinics. There is an urgent need in developing national palliative care program to improve the understanding of end-of-life care in our medical oncology clinics.

Patterns of hospice use in patients dying from hematologic malignancies

BACKGROUND

Hospice brings substantial clinical benefits to dying patients and families but is underutilized by patients dying of hematologic malignancies (HM); nationwide, only 2% of HM patients use hospice. There are 70,000 deaths among U.S. patients with hematologic malignancies yearly.

OBJECTIVE

We measured the use and length of stay (LOS) in hospice among patients with HMs at a large academic cancer center.

DESIGN

This was a single center retrospective review of adult patients (≥18 years) with lymphoma, leukemia, myelodysplastic syndrome, aplastic anemia, and multiple myeloma referred for hospice.

MEASUREMENTS

Information included demographics, transplant, hospice type, LOS, and use of "expanded access" services.

RESULTS

Fifty-nine patients were referred to hospice, and 53 utilized hospice services, 25% of 209 HM decedents. Thirty-five received home hospice and 18 used inpatient hospice. The median home hospice LOS was nine days (SD 13) and inpatient hospice six days (SD 10). Nine patients with "expanded access" hospice received only a few blood transfusions, and none received radiation.

CONCLUSIONS

HM patients are referred late or never for hospice services. Studies evaluating earlier integration of palliative and hospice care with usual HM care are warranted. We present a one-page negotiation form that we have found useful in negotiations among HM physicians, hospice medical directors, and payers.

Assessment of patients' dignity in cancer care: preliminary psychometrics of the German version of the Patient Dignity Inventory (PDI-G)

CONTEXT

The Patient Dignity Inventory (PDI) is a valid and reliable instrument designed to measure different sources of dignity-related distress in cancer patients receiving palliative care.

OBJECTIVES

We investigated item characteristics, factor structure, reliability, and concurrent validity of the German version of the PDI (PDI-G) among patients with cancer.

METHODS

PDI was translated into the German language following state-of-the-art criteria. In a sample of 112 inpatients with mixed tumor types, principal component analysis, reliability analysis (Cronbach's coefficient alpha), and correlation analysis were performed. Concurrent validity was evaluated by validated measures of distress, demoralization, anxiety, depression, hopelessness, quality of life, sense of meaning and purpose, and supportive care needs.

RESULTS

Cronbach's coefficient alpha for PDI-G was 0.96; factor analysis resulted in a four-factor solution, accounting for 71% of the overall variance, with factor loadings ranging from 0.49 to 0.86. Factor labels include Loss of Sense of Worth and Meaning, Anxiety and Uncertainty, Physical Symptom Distress and Body Image, and Loss of Autonomy, showing high internal consistencies ranging from Cronbach's α 0.80 to 0.95. Evidence for concurrent validity was established by significant associations between PDI-G scales and concurrent measures of distress.

CONCLUSION

Although we were unable to replicate the five-factor structure provided by Chochinov, this study gave strong support to an alternative four-factor solution of PDI-G, capturing all 25 items. We conclude that PDI-G is a psychometrically sound instrument assessing a broad range of dignity-related distress issues in patients with cancer.

Intensive care for the cancer patient - unique clinical and ethical challenges and outcome prediction in the critically ill cancer patient

With the rising number of cancer cases and increasing survival times, cancer patients with critical illness are increasingly presenting to the intensive care unit. This article considers the unique challenges they pose in terms of oncological-specific disease processes and treatment and reviews current trends in outcome prediction. We also consider the ethical standpoints surrounding the treatment of patients for whom there may be no cure and their subsequent transition to palliative care, should it become necessary.

Communication and advanced care planning in palliative and end-of-life care

Communication about and planning for the end of life has evolved with medical and technological changes. This article presents a focused literature review of Advance Directives (ADs), Advanced Care Planning (ACP), and communication in palliative and end-of-life care. Two focused Medline searches were conducted to locate articles that addressed ACP in the U.S. Content analysis was utilized to summarize and categorize the literature into five domains: (1) ADs, (2) ACP and communication, (3) Barriers to ACP, (4) Differential domains of ACP, and (5) Interventions to enhance the process. Policies and protocols for ACP and communication have been developed to facilitate the process in different patient populations and locations of care. Effective ACP is an essential component of person-centered end-of-life and palliative care.

Intensive care of the cancer patient: recent achievements and remaining challenges

A few decades have passed since intensive care unit (ICU) beds have been available for critically ill patients with cancer. Although the initial reports showed dismal prognosis, recent data suggest that an increased number of patients with solid and hematological malignancies benefit from intensive care support, with dramatically decreased mortality rates. Advances in the management of the underlying malignancies and support of organ dysfunctions have led to survival gains in patients with life-threatening complications from the malignancy itself, as well as infectious and toxic adverse effects related to the oncological treatments. In this review, we will appraise the prognostic factors and discuss the overall perspective related to the management of critically ill patients with cancer. The prognostic significance of certain factors has changed over time. For example, neutropenia or autologous bone marrow transplantation (BMT) have less adverse prognostic implications than two decades ago. Similarly, because hematologists and oncologists select patients for ICU admission based on the characteristics of the malignancy, the underlying malignancy rarely influences short-term survival after ICU admission. Since the recent data do not clearly support the benefit of ICU support to unselected critically ill allogeneic BMT recipients, more outcome research is needed in this subgroup. Because of the overall increased survival that has been reported in critically ill patients with cancer, we outline an easy-to-use and evidence-based ICU admission triage criteria that may help avoid depriving life support to patients with cancer who can benefit. Lastly, we propose a research agenda to address unanswered questions.

How I conduct the family meeting to discuss the limitation of life-sustaining interventions: a recipe for success

The meeting with the family of a hospitalized patient dying with advanced cancer or hematologic disease in which the limitation of life-sustaining interventions is discussed can be a challenge, particularly for junior physicians. A successful conclusion to this discussion involves an outcome in which the family, without coercion or manipulation, comes to accept that the appropriate care has been provided to their loved one, while the caregivers are enabled to provide care that is goal-directed and patient-centered. This type of result can be achieved through an approach in which patient-focused recommendations are offered in the context of diligent efforts to establish and sustain trust, thoughtful preparation, and respectful discussions with the family.
