Integrating palliative care with intensive care for critically ill patients with lung cancer

Integrated palliative care: triggers for referral to palliative care in ICU patients

INTRODUCTION

Palliative care within intensive care units (ICU) benefits decision-making, symptom control, and end-of-life care. It has been shown to reduce the length of ICU stay and the use of non-beneficial and unwanted life-sustaining therapies. However, it is often initiated late or not at all. There is increasing evidence to support screening ICU patients using palliative care referral criteria or "triggers". The aim of the project was to assess the need for palliative care referral during ICU admission using "trigger" tools.

METHODS

Electronic record review of cancer patients who died in or within 30 days of discharge from oncology ICU, between 2016 and 2018. Patients referred to palliative care before or during ICU admission were identified. Three sets of palliative care referral "triggers" were applied: one that is being tested locally and two internationally derived tools. The proportion of patients who met any of these triggers during their final ICU admission was calculated.

RESULTS

Records of 149 patients were reviewed: median age 65 (range 20-83). Most admissions (89%) were unplanned, with the most common diagnoses being haemato-oncology (31%) and gastrointestinal (16%) cancers. Most (73%) were unknown to palliative care pre-ICU admission; 44% were referred between admission and death. The median time from referral to death was 0 day (range 0-19). On ICU admission, 97-99% warranted referral to palliative care using locally and internationally derived triggers.

CONCLUSION

All "trigger" tools identified a high proportion of patients who may have warranted a palliative care referral either before or during admission to ICU. The routine use of trigger tools could help streamline referral pathways and underpin the development of an effective consultative model of palliative care within the ICU setting to enhance decision-making about appropriate treatment and patient-centred care.

Patient preference for oral chemotherapy in the treatment of metastatic breast and lung cancer

OBJECTIVES

Although new therapies against metastatic cancer have been developed in recent decades, chemotherapy is still an important treatment option. Prolonged treatment and side-effects are often discouraging for patients, and in many cases, therapy is only palliative, not curative. This study explores patient preference for oral or intravenous (IV) chemotherapy in the treatment of metastatic breast or lung cancer.

METHODS

It is a descriptive, open label, multicentre, nation-wide study, in which a 16-item questionnaire consisting of single-choice questions scored on a 5-point Likert scale was administered to patients in a single visit, and another 11-item questionnaire was self-administered by the patient's oncologist.

RESULTS

A total of 131 breast and lung cancer specialists at 64 hospitals enrolled 412 patients (lung cancer = 161; breast cancer = 251). To be eligible, patients must have already received IV therapy and at least 2 cycles of oral chemotherapy. Most (77%) patients expressed preference for oral therapy. Most considered their daily life was less disrupted with tablets (70.4%), had no trouble swallowing them (86.9%), and were not concerned about forgetting to take them (56.8%). Half (56.3%) were worried about problems related to drug infusion with IV therapy, 61.7% were concerned about nurses failing to find a suitable vein, and 63.1% were dissatisfied with hospital waiting times. A uniform response was obtained from both samples of patients.

CONCLUSION

Convenience, ease of administration, fewer side effects and better quality of life tilt the balance towards oral drug administration.

Variability in triage practices for critically ill cancer patients: A randomized controlled trial

PURPOSE

Intensive care triage practices and end-user interpretation of triage guidelines have rarely been assessed. We evaluated agreement between providers on the prioritization of patients for ICU admission using different triage guidelines.

MATERIALS AND METHODS

A multi-centered randomized study on providers from 18 different countries was conducted using clinical vignettes of oncological patients. The level of agreement between providers was measured using two different guidelines, with one being cancer specific.

RESULTS

Amongst 257 providers, 52.5% randomly received the Society of Critical Care Prioritization Model, and 47.5% received a cancer specific flowchart as a guide. In the Prioritization Model arm the average entropy was 1.193, versus 1.153 in the flowchart arm (P = .095) indicating similarly poor agreement. The Fleiss' kappa coefficients were estimated to be 0.2136 for the SCCMPM arm and 0.2457 for the flowchart arm, also similarly implying poor agreement.

CONCLUSIONS

The low agreement amongst practitioners on the prioritization of cancer patient cases for ICU admission existed using both general triage guidelines and guidelines tailored only to cancer patients. The lack of consensus on intensive care unit triage practices in the oncological population exposes a potential barrier to appropriate resource allocation that needs to be addressed.

Dying in intensive care units of India: Commentaries on policies and position papers on palliative and end-of-life care

PURPOSE

This study critically examines the available policy guidelines on integration of palliative and end-of-life care in Indian intensive care units to appraise their congruence with Indian reality.

MATERIALS AND METHODS

Six position statements and guidelines issued by the Indian Society for Critical Care Medicine and the Indian Association of Palliative Care from 2005 till 2015 were examined. The present study reflects upon the recommendations suggested by these texts.

RESULT

Although the policy documents conform to the universally set norms of introducing palliative and end-of-life care in intensive care units, they hardly suit Indian reality. The study illustrates local complexities that are not addressed by the policy documents. This include difficulties faced by intensivists and physicians in arriving at a consensus decision, challenges in death prognostication, hurdles in providing compassionate care, providing "culture-specific" religious and spiritual care, barriers in effective communication, limitations of documenting end-of-life decisions, and ambiguities in defining modalities of palliative care. Moreover, the policy documents largely dismiss special needs of elderly patients.

CONCLUSION

The article suggests the need to reexamine policies in terms of their attainability and congruence with Indian reality.

ICU Deaths in Patients With Advanced Cancer

BACKGROUND

A significant number of advanced cancer admissions to the intensive care unit (ICU) are inappropriate in that they do not result in prolonged survival. No clear consensus criteria for reasonable admissions of advanced cancer patients have been developed.

METHOD

We established four criteria for reasonable admissions to ICU in patients who suffered from advanced, incurable cancer: post procedure complication, recent notification of cancer, ECOG performance status of 0-1, and life expectancy of more than 6 months. Based on these criteria, we reviewed the charts of all patients who died in the ICU at the University of Tennessee Health Science Center (UTHSC) affiliated Veteran's Affairs Medical Center between 10/2005 and 10/2010. We identified patients with advanced, incurable cancer and performed an in depth review of their charts.

RESULTS

In the 421 charts of patients who died in our ICU between October 2005 and October 2010 we identified 52 patients admitted to the ICU with advanced, incurable cancer. 14 patients were diagnosed with cancer one month or less prior to admission. 21 patients had ECOG performance status of 0-1. 14 patients had life expectancy of more than 6 months and 8 patients were admitted for post procedure complication. 47% of patients who did not satisfy any of our reasonable admission criteria had APDs.

CONCLUSIONS

Incorporating proposed admission criteria in ICU admission guidelines may prevent 37% of inappropriate, advanced cancer admissions to the ICU. A simple increase in numbers of APDs would not likely change significantly the numbers of inappropriate ICU admissions.

Palliative care in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is the only major worldwide cause of mortality that is currently increasing in prevalence. Furthermore, COPD is incurable, and the only therapy that has been shown to increase survival is oxygen therapy in selected patients. Compared to patients with cancer, patients with COPD experience similar levels of pain, breathlessness, fatigue, depression, and anxiety and have a worse quality of life but have comparatively little access to palliative care. When these patients do receive palliative care, they tend to be referred later than patients with cancer. Many disease, patient-, and provider-related factors contribute to this phenomenon, including COPD's unpredictable course, misperceptions of palliative care among patients and physicians, and lack of advance care planning discussions outside of crisis situations. A new paradigm for palliative care would introduce palliative treatments alongside, rather than at the exclusion of disease-modifying interventions. This integrated approach would circumvent the issue of difficult prognostication in COPD, as any patient would receive individualized palliative interventions from the time of diagnosis. These points will be covered in this review, which discusses the challenges in providing palliative care to COPD patients, the strategies to mitigate the challenges, management of common symptoms, and the evidence for integrated palliative care models as well as some suggestions for future development.

A Prospective Evaluation of Symptom Prevalence and Overall Symptom Burden Among Cohort of Critically Ill Cancer Patients

Background:

Gross physiological perturbations necessitating the Intensive Care Unit (ICU) admission might exacerbate the already existing or initiate bothersome symptoms among cancer patients. There is a lack of conclusive evidence concerning the symptomatic experience among this subgroup of cancer patients particularly so in the Indian population. The aim of this prospective observational study was to elucidate the symptom prevalence and overall symptomatic distress among critically ill cancer patients at the time of admission to a medical ICU.

Methods:

We prospectively evaluated 110 consecutive cancer patients at the time of admission to our medical ICU for the presence and intensity of symptoms using a modified Edmonton Symptom Assessment Scale (ESAS). The patients/caregivers were also enquired regarding the most bothersome symptom in the past 1 week and the presence of “symptom associated sleep disturbance.” The primary outcome was the prevalence of patients with moderate (ESAS ≥ 40) and severe (ESAS ≥ 70) symptomatic distress.

Results:

The average age was 52.49 years with 75.45% of the respondents in the economically productive age group (21–60 years). Carcinoma breast (19.35%) and lung (14.58%) were the most common cancers among females and males, respectively. 87.27% and 60% of the patients had advanced cancer and multi-organ dysfunction, respectively. About 76.36% patients were able to complete ESAS either by themselves or with caregiver's assistance within first 24 h of ICU admission. The mean ESAS distress score was 48.04 (0–81) with 72.72% of the patients having moderate-severe symptomatic distress. Loss of appetite (92.73%) and nausea (54.55%) were the most common and the least common reported symptoms, respectively. Pain was the most common and “most distressing symptom” reported by 40% of patients with 64.55% patients reporting one or more symptoms severe enough to interfere with their sleep.

Conclusion:

ESAS is a user-friendly cognitive aid to make the healthcare team cognizant of the symptom existence and overall symptomatic burden among cancer patients with gross physiological perturbations. The high prevalence of moderate-severe symptom distress requires the concomitant provision of palliative and intensive care among this group of cancer patients.

Management of intra-abdominal hypertension and abdominal compartment syndrome: a review

Patients in the intensive care unit (ICU) are at risk of developing of intra abdominal hypertension (IAH) and abdominal compartment syndrome (ACS).

AIM

This review seeks to define IAH and ACS, identify the aetiology and presentation of IAH and ACS, identify IAP measurement techniques, identify current management and discuss the implications of IAH and ACS for nursing practice. A search of the electronic databases was supervised by a health librarian. The electronic data bases Cumulative Index of Nursing and Allied Health Literature (CINAHL); Medline, EMBASE, and the World Wide Web was undertaken from 1996- January 2011 using MeSH and key words which included but not limited to: abdominal compartment syndrome, intra -abdominal hypertension, intra-abdominal pressure in adult populations met the search criteria and were reviewed by three authors using a critical appraisal tool. Data derived from the retrieved material are discussed under the following themes: (1) etiology of intra-abdominal hypertension; (2) strategies for measuring intra-abdominal pressure (3) the manifestation of abdominal compartment syndrome; and (4) the importance of nursing assessment, observation and interventions. Intra-abdominal pressure (IAP) and abdominal compartment syndrome (ACS) have the potential to alter organ perfusion and compromise organ function.

Palliative care in the ICU: relief of pain, dyspnea, and thirst--a report from the IPAL-ICU Advisory Board

PURPOSE

Pain, dyspnea, and thirst are three of the most prevalent, intense, and distressing symptoms of intensive care unit (ICU) patients. In this report, the interdisciplinary Advisory Board of the Improving Palliative Care in the ICU (IPAL-ICU) Project brings together expertise in both critical care and palliative care along with current information to address challenges in assessment and management.

METHODS

We conducted a comprehensive review of literature focusing on intensive care and palliative care research related to palliation of pain, dyspnea, and thirst.

RESULTS

Evidence-based methods to assess pain are the enlarged 0-10 Numeric Rating Scale (NRS) for ICU patients able to self-report and the Critical Care Pain Observation Tool or Behavior Pain Scale for patients who cannot report symptoms verbally or non-verbally. The Respiratory Distress Observation Scale is the only known behavioral scale for assessment of dyspnea, and thirst is evaluated by patient self-report using an 0-10 NRS. Opioids remain the mainstay for pain management, and all available intravenous opioids, when titrated to similar pain intensity end points, are equally effective. Dyspnea is treated (with or without invasive or noninvasive mechanical ventilation) by optimizing the underlying etiological condition, patient positioning and, sometimes, supplemental oxygen. Several oral interventions are recommended to alleviate thirst. Systematized improvement efforts addressing symptom management and assessment can be implemented in ICUs.

CONCLUSIONS

Relief of symptom distress is a key component of critical care for all ICU patients, regardless of condition or prognosis. Evidence-based approaches for assessment and treatment together with well-designed work systems can help ensure comfort and related favorable outcomes for the critically ill.
