Dying with lung cancer or chronic obstructive pulmonary disease: insights from SUPPORT. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments

Palliative care in lung cancer: ACCP evidence-based clinical practice guidelines (2nd edition)

GOALS/OBJECTIVES: To review the scientific evidence on symptoms and specific complications that are associated with lung cancer, and the methods available to palliate those symptoms and complications.

METHODS

MEDLINE literature review (through March 2006) for all studies published in the English language, including case series and case reports, since 1966 using the following medical subject heading terms: bone metastases; brain metastases; cough; dyspnea; electrocautery; hemoptysis; interventional bronchoscopy; laser; pain management; pleural effusions; spinal cord metastases; superior vena cava syndrome; and tracheoesophageal fistula.

RESULTS

Pulmonary symptoms that may require palliation in patients who have lung cancer include those caused by the primary cancer itself (dyspnea, wheezing, cough, hemoptysis, chest pain), or locoregional metastases within the thorax (superior vena cava syndrome, tracheoesophageal fistula, pleural effusions, ribs, and pleura). Respiratory symptoms can also result from complications of lung cancer treatment or from comorbid conditions. Constitutional symptoms are common and require attention and care. Symptoms referable to distant extrathoracic metastases to bone, brain, spinal cord, and liver pose additional problems that require a specific response for optimal symptom control. There are excellent scientific data regarding the management of many of these issues, with lesser evidence from case series or expert opinion on other aspects of providing palliative care for lung cancer patients.

CONCLUSIONS

Palliation of symptoms and complications in lung cancer patients is possible, and physicians who provide such care must be knowledgeable about these issues.

Advanced chronic obstructive pulmonary disease: innovative approaches to palliation

By the year 2020, chronic obstructive pulmonary disease (COPD) will be the third leading cause of death globally. While there have been consistent calls for increased palliative care involvement in the care of patients with advanced COPD, these calls should be based on empirical evidence that such an approach improves the symptom burden and poor quality of life associated with advanced COPD. Rather than reviewing the traditional treatments of airflow obstruction and palliative measures familiar to the palliative care community, we will focus on some novel approaches to the management of patients with advanced COPD from the perspective of clinicians involved in end of life care provision and research. By combining the clinical and research skills of pulmonologists and palliative medicine specialists we can advance the care of patients with this progressive and incurable disease.

The clinical management in extremely severe COPD

Chronic obstructive pulmonary disease (COPD) affects 6% of the general population and is the fourth-leading cause of death in the United States with severe and very severe disease accounting for 15% and 3% of physician diagnoses of COPD. Guidelines make few recommendations regarding providing the provision of care for the most severe stages of disease, namely Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages III and IV with chronic respiratory failure. The effectiveness of inhaled drug therapy in very severe patients has not been assessed yet. Health care systems in many countries include public funding of long-term oxygen therapy for eligible candidates. Currently, there is little evidence for the use of mechanical ventilatory support in the routine management of hypercapnic patients. Pulmonary rehabilitation should be considered as a significant component of therapy, even in the most severe patients. Although Lung Volume Reduction Surgery has been shown to improve mortality, exercise capacity, and quality of life in selected patients, this modality is associated with significant morbidity and an early mortality rate in the most severe patients. Despite significant progress over the past 25 years, both short- and long-term outcomes remain significantly inferior for lung transplantation relative to other "solid" organ recipients. Nutritional assessment and management is an important therapeutic option in patients with chronic respiratory diseases. Morphine may significantly reduce dyspnoea and does not significantly accelerate death. No consistent improvement in dyspnoea over placebo has been shown with anxiolytics. Supplemental oxygen during exercise reduces exertional breathlessness and improves exercise tolerance of the hypoxaemic patient. Non-invasive ventilation has been used as a palliative treatment to reduce dyspnoea. Hypoxaemic COPD patients, on long-term oxygen therapy, may show reduced health-related quality of life, cognitive function, and depression. Only a small proportion of patients with severe COPD discuss end-of-life issues with their physicians.

The early identification of palliative care patients: preliminary processes and estimates from urban, family medicine practices

Primary care providers are positioned to identify patients, well in advance of their deaths, who could benefit from palliative care services, but little is known about how to correctly identify these upstream palliative care patients. This article reports on efforts to devise a methodology for identifying such patients and to offer preliminary estimates of their prevalence in urban, primary care practices. The data presented here suggest 2 conclusions: (1) that electronic databases may be used to create a preliminary screen to assist clinicians in the early identification of patients in need of palliative care, and (2) that 1% to 3% of patients in primary care practices may benefit from palliative care services. Currently, there are no standards regarding the role of primary care providers in end-of-life care and it is hoped that this article will contribute to developing such standards.

Proactive palliative care in the medical intensive care unit: effects on length of stay for selected high-risk patients

OBJECTIVE

The purpose of this study was to examine the effect of proactive palliative care consultation on length of stay for high-risk patients in the medical intensive care unit (MICU).

DESIGN

A prospective pre/post nonequivalent control group design was used for this performance improvement study.

SETTING

Seventeen-bed adult MICU.

PATIENTS

Of admissions to the MICU, 191 patients were identified as having a serious illness and at high risk of dying: 65 patients in the usual care phase and 126 patients in the proactive palliative care phase. To be included in the sample, a patient had to meet one of the following criteria: a) intensive care admission following a current hospital stay of >or=10 days; b) age >80 yrs in the presence of two or more life-threatening comorbidities (e.g., end-stage renal disease, severe congestive heart failure); c) diagnosis of an active stage IV malignancy; d) status post cardiac arrest; or e) diagnosis of an intracerebral hemorrhage requiring mechanical ventilation.

INTERVENTIONS

Palliative care consultations.

MEASUREMENTS AND MAIN RESULTS

Primary measures were patient lengths of stay a) for the entire hospitalization; b) in the MICU; and c) from MICU admission to hospital discharge. Secondary measures included mortality rates and discharge disposition. There were no significant differences between the usual care and proactive palliative care intervention groups in respect to age, gender, race, screening criteria, discharge disposition, or mortality. Patients in the proactive palliative care group had significantly shorter lengths of stay in the MICU (8.96 vs. 16.28 days, p = .0001). There were no differences between the two groups on total length of stay in the hospital or length of stay from MICU admission to hospital discharge.

CONCLUSIONS

Proactive palliative care consultation was associated with a significantly shorter MICU length of stay in this high-risk group without any significant differences in mortality rates or discharge disposition.

The quality of obstructive lung disease care for adults in the United States as measured by adherence to recommended processes

BACKGROUND

The extent to which patients with obstructive lung disease receive recommended processes of care is largely unknown. We assessed the quality of care delivered to a national sample of the US population.

METHODS

We extracted medical records for 2 prior years from consenting participants in a random telephone survey in 12 communities and measured the quality of care provided with 45 explicit, process-based quality indicators for asthma and COPD developed using the modified Delphi expert panel methodology. Multivariate logistic regression evaluated effects of patient demographics, insurance, and other characteristics on the quality of health care.

RESULTS

We identified 2,394 care events among 260 asthma participants and 1,664 events among 169 COPD participants. Overall, participants received 55.2% of recommended care for obstructive lung disease. Asthma patients received 53.5% of recommended care; routine management was better (66.9%) than exacerbation care (47.8%). COPD patients received 58.0% of recommended care but received better exacerbation care (60.4%) than routine care (46.1%). Variation was seen in mode of care with considerable deficits in documenting recommended aspects of medical history (41.4%) and use of diagnostic studies (40.1%). Modeling demonstrated modest variation between racial groups, geographic areas, insurance types, and other characteristics.

CONCLUSIONS

Americans with obstructive lung disease received only 55% of recommended care. The deficits and variability in the quality of care for obstructive lung disease present ample opportunity for quality improvement. Future endeavors should assess reasons for low adherence to recommended processes of care and assess barriers in delivery of care.

[Symptom control and ethics in final stages of COPD]

On the basis of a case study, the complex problems of the final stages of a COPD will be demonstrated and discussed. Dyspnea and anxiousness are the primary symptoms. If they can be adequately brought under control by opiates and benzodiazepines, a palliative sedation is then not necessary. The communicative and ethical demands on the team responsible are high. It is important to be aware of the specific needs of the patient and of his/her family members, and to competently accompany the patient throughout the decision-making process--such as the decision to end respiratory therapy, for example. Clarifying the situation with the patient and finding out his/her wishes, accompanied by the corresponding documentation, is advisable.

Outcome and Code Status of Lung Cancer Patients Admitted to the Medical ICU

OBJECTIVES

To determine the outcome of lung cancer patients admitted to the medical ICU (MICU), to examine their code status at MICU admission and prior to death, and to determine which subspecialty physician was responsible for the change in code status.

DESIGN

Retrospective chart review study.

SETTING

A 19-bed MICU in a tertiary-care university hospital.

PATIENTS

Consecutive patients with a diagnosis of lung cancer admitted to the MICU from July 2002 to June 2004.

MEASUREMENTS AND MAIN RESULTS

Forty-seven patients with a diagnosis of lung cancer accounted for 53 MICU admissions. Mean (+/- SD) age at MICU admission was 65 +/- 10 years. Sixty-six percent were male. Eighty-three percent had non-small cell lung cancer (NSCLC); 64% of these were stage IV NSCLC. The most common organ system implicated on MICU admission was pulmonary, with 38% of patients presenting with pneumonia. Overall MICU mortality was 43%, and in-hospital mortality was 60%. Patients who required mechanical ventilation or had more advanced lung cancer stage had the worst prognosis, with mortality rates of 74% and 68%, respectively. Seventy-four percent of patients were "full code" at MICU admission. Subsequently, the code status was changed to "do not resuscitate" in 49% of these cases. The pulmonary/critical care physician was involved in this change 96% of the time and was the sole physician in 65% of cases.

CONCLUSIONS

This study confirms that patients with lung cancer admitted to the MICU have a high mortality. Despite this, the majority of patients are full code on MICU admission. Pulmonary/critical care physicians play an important role in the end-of-life decision making of lung cancer patients admitted to the MICU, perhaps because of their availability in the MICU and also because of their sense of responsibility in maintaining and withdrawing life support.

Palliative care and pain management

Palliative care aims to improve quality of life and relieve suffering for patients with advanced illness and those close to them by specifically addressing communication, symptom management, coordination of care, psychosocial and spiritual realms, grief and bereavement support, and legal and ethical concerns. It has an interdisciplinary focus and may co-exist with curative and life-prolonging treatment. Palliative care is a key component of appropriate, routine medical care, especially for clinicians caring for older adults. In revisiting Mrs. B, the many needs of a typical elderly patient are apparent, as are the gaps in the current level of care. A discussion of prognosis and goals of care is a potential starting point. This includes obtaining input from an oncologist with regard to treatment options for Mrs. B's metastatic breast cancer and her pathologic hip fracture. Soliciting her treatment goals in the context of her chronic obstructive pulmonary disease and significant recent decline is the next challenge. Pain, dyspnea, constipation, anorexia, and anxiety could then be addressed with pointed assessment and symptom-specific management. Code status discussion, communication with her support network, and care coordination for her increased care needs would follow. Hospice should be introduced as a potential option. Advance care planning might also be initiated. Psychological and spiritual support needs could also be explored in time. Clearly, there is much to be done for Mrs. B and her loved ones in clarifying and coordinating whatever path comes to be. Older patients and their families face prolonged courses of chronic disease and gradual decline. Physicians caring for these patients need to be expert in the domains of palliative care so these patients and their families can receive the best quality of care while they are still living full lives and later as they approach the end of life.

People with chronic obstructive pulmonary disease at the end of life: A review of the literature

Based on 2004 data, chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the world, surpassed only by cardiovascular disease, pneumonia and HIV/AIDS. The terminal trajectory of patients with COPD is distinct from that of cancer patients. The unpredictability of prognosis for people with COPD poses different challenges in end-of-life decision-making from those faced by individuals with terminal cancer. The use of a traditional cancer-based service model to predict the need for palliative care services is not helpful for people with COPD. Drastic improvements in end of life care for the people with COPD are essential, especially with the projected rise in cases over the coming years.

Comparison of Medical Treatments for the Dying in a Hospice and a Geriatric Hospital in Japan

CONTEXT

Most older adults who die in Japan do so in the hospital without receiving hospice or palliative care. While there are some hospices in Japan, little is known about the care they provide to the elderly.

OBJECTIVE

To clarify how the care of dying patients differs in a hospice and a geriatric hospital in Japan.

DESIGN

Cohort study.

SETTING

A hospice and a geriatric hospital in Japan.

PARTICIPANTS

One hundred ninety-one inpatients aged 65 or older.

MAIN OUTCOME

Areas of our interest: (1) gender and age; (2) primary disease(s) and cause of death; (3) observed symptoms/conditions and medical treatment or care conducted within 48 hours prior to death; (4) the actual topics leading to disclosure; and (5) whether or not advance directives had been given.

RESULTS

The X2 test determined that there were statistically significant differences between a geriatric hospital and a hospice, with respect to mean age, diagnoses on admission, primary cause of death, symptoms/conditions, and the practice of medical interventions. However, controlling for patient characteristics and assuming a bivariate distribution between the probabilities of choosing a facility and of undergoing a medical procedure, we found that patients at the hospice were more likely to undergo treatment with opioids, urethral catheter, and oral medicine; such patients were less likely to undergo oxygen inhalation, total parenteral nutrition, and other intravenous drips.

CONCLUSION

The hospice examined in this study was similar to the approach regarding medical treatments observed at the geriatric hospital.

A comparison of symptom prevalence in far advanced cancer, AIDS, heart disease, chronic obstructive pulmonary disease and renal disease

Little attention has been paid to the symptom management needs of patients with life-threatening diseases other than cancer. In this study, we aimed to determine to what extent patients with progressive chronic diseases have similar symptom profiles. A systematic search of medical databases (MEDLINE, EMBASE, and PsycINFO) and textbooks identified 64 original studies reporting the prevalence of 11 common symptoms among end-stage patients with cancer, acquired immunodeficiency syndrome (AIDS), heart disease, chronic obstructive pulmonary disease, or renal disease. Analyzing the data in a comparative table (a grid), we found that the prevalence of the 11 symptoms was often widely but homogeneously spread across the five diseases. Three symptoms-pain, breathlessness, and fatigue-were found among more than 50% of patients, for all five diseases. There appears to be a common pathway toward death for malignant and nonmalignant diseases. The designs of symptom prevalence studies need to be improved because of methodological disparities in symptom assessment and designs.

Becky's legacy: personal and professional reflections on loss and hope

The author, a psychologist who has been specializing in end-of-life issues for over a decade, uses the death of his fiancée (Becky), following the withdrawal of a ventilator and the refusal to place her back on the machine, to discuss research and analysis of end-of-life care in the United States. After briefly discussing his own background, Becky's history, and their relationship, he details Becky's last weeks of life and the first weeks of his grieving process. This story provides a background for discussing end-of-life issues including what constitutes a "good death," concerns about aggressive treatment and the cost of care near the end of life, prognosis, advance directives, and demographic issues. There is also a major section on psychosocial issues that arise when a person is dying. The author concludes with a set of "lessons learned" as a result of his relationship with Becky and going through the dying process with her and her family.

Ethnic differences in pain among outpatients with terminal and end-stage chronic illness

OBJECTIVE

To explore ethnic and country of origin differences in pain among outpatients with terminal and end-stage chronic illness.

DESIGN

Cohort study within a year-long trial of a palliative care consultation.

SETTING

Outpatient general medicine practice in an academic medical center.

PATIENTS

Ninety patients with advanced congestive heart failure, chronic obstructive pulmonary disease, or cancer, and with a prognosis between 1 and 5 years.

OUTCOME MEASURES

Patients' report of pain using the Brief Pain Inventory and analgesic medications prescribed by primary care physicians. Differences in pain report and treatment were assessed at study entry, at 6 and 12 months.

RESULTS

The overall burden of pain was high. Patients of color reported more pain than white patients, including measures of least pain (P = 0.02), average pain (P = 0.05), and current pain (P = 0.03). No significant ethnic group differences in pain were found comparing Asian, black, and Latino patients. Although nearly all patients who were offered opioid analgesics reported using them, opioids were rarely prescribed to any patient. There were no differences in pain between patients born in the U.S. and immigrants.

CONCLUSIONS

Pain is common among outpatients with both terminal and end-stage chronic illness. There do not appear to be any differences in pain with regard to country of origin, but patients of color report more pain than white patients. Patients of all ethnicities are inadequately treated for their pain, and further study is warranted to explore the relative patient and physician contributions to the finding of unequal symptom burden and inadequate treatment effort.

Barriers and Facilitators to End-of-Life Care Communication for Patients with COPD

OBJECTIVE

Patients with COPD frequently do not discuss end-of-life care with physicians; therefore, we sought to identify the barriers and facilitators to this communication as a first step to overcoming barriers and capitalizing on facilitators.

DESIGN

Fifteen barriers and 11 facilitators to patient-physician communication about end-of-life care were generated from focus groups of patients with COPD. We subsequently conducted a cross-sectional study of 115 patients with oxygen-dependent COPD and their physicians to identify the common barriers and facilitators and examine the association of these barriers and facilitators with communication about end-of-life care.

PARTICIPANTS AND SETTING

Patients with oxygen-dependent COPD were recruited from clinics at a university, county, and Veterans Affairs teaching hospital, and an oxygen delivery company. We also recruited the physician identified by each patient as the doctor primarily responsible for their lung disease.

MEASUREMENTS AND RESULTS

Patients were interviewed by trained research interviewers. Physician data collection was completed by mail survey. Participation rates were 40% for patients and 86% for physicians. Only 32% of patients reported having a discussion about end-of-life care with their physician. Two of 15 barriers and 8 of 11 facilitators were endorsed by > 50% of patients. The most commonly endorsed barriers were "I'd rather concentrate on staying alive," and "I'm not sure which doctor will be taking care of me." Two barriers were significantly associated with lack of communication, as follows: "I don't know what kind of care I want," and "I'm not sure which doctor will be taking care of me." The greater the number of barriers endorsed by patients, the less likely they were to have discussed end-of-life care with physicians (p < 0.01), suggesting the validity of these barriers. Conversely, the more facilitators, the more likely patients were to report having had end-of-life discussions with their physicians (p < 0.001).

CONCLUSION

Although patients endorsed many barriers and facilitators, few barriers were endorsed by most patients. Barriers and facilitators associated with communication are targets for interventions to improve end-of-life care, but such interventions will likely need to address the specific barriers relevant to individual patient-physician pairs.

End-of-life care: an agenda for policy improvement

Current arrangements for health care in the United States do not adequately address the needs of a growing population that has serious, eventually fatal chronic illness. New programs and policies are necessary to encourage coordination of care; better match services to the needs of patients; better provide education and incentives; and better support formal and informal caregivers. Models of end-of-life care, such as MediCaring, are described along with a research and policy agenda that focuses on modifying the health care system and building on new innovations.

The role of rehabilitation medicine and palliative care in the treatment of patients with end-stage disease

Rehabilitation medicine and palliative care share many common goals. They strive to maximize physical function and emotional well-being to the highest extent possible given the nature of the underlying disease process. Many patients with end-stage disease experience symptoms and functional losses that diminish their quality of life. This article outlines the benefits that active rehabilitation therapy can provide to patients in the terminal stages of their disease and some of the ethical and practical issues faced in the planning and provision of this care.

A conceptual framework for end-of-life care: A reconsideration of factors influencing the integrity of the human person

In this article, we examine emerging themes in the research and theoretical literature on care at the end of life to develop a conceptual framework to guide further research in this area. The integrity of the human person is the organizing concept, and the spiritual domain is at the core of the psychological, physical, and functional domains. This framework extends beyond previous frameworks for care at the end of life by including the relationship of the health professional and the health care organization to the integrity of the person. Also, outcomes in this framework extend beyond quality of life and comfort to include patient decision-making methods and achievement of life goals. Attention is given to the cultural dimension of personhood in our multicultural society, and the definition of end of life is expanded to include both the acute phase of terminal illness and the frailty of health associated with advanced age.

Living with severe chronic obstructive pulmonary disease (COPD): perceptions of patients and their carers. An interpretative phenomenological analysis

BACKGROUND

A study designed to explore the experiences of patients with severe chronic obstructive pulmonary disease (COPD) and their carers, particularly with regard to ongoing and palliative care needs.

METHODS

The participants were nine men and one woman with severe COPD and the carers of eight of the men, in East Devon, UK. Semi-structured interviews were undertaken, transcribed and analysed using interpretative phenomenological analysis (IPA).

RESULTS

The emergent themes were of losses, adaptation, relationships with health professionals and effect on carer. Losses reflected the loss of personal liberty and dignity and of previous expectations of the future. Adaptation included strategies to cope with the effects of the disease. Relationships related to both positive and negative aspects of contact with health professionals. There was appreciation for continuity of care and reassurance. The effect on the carer was evident particularly as they had to take on multiple roles. They also experienced some of the same losses as the patient and appeared enmeshed with the illness.

CONCLUSIONS

This study confirmed the inexorable decline in activities of daily life and social isolation for patients with severe COPD. Adaptive strategies were common and some positive aspects were identified. Support from the primary health care team was appreciated. The strain on carers was very apparent. The concept of a more structured sharing of information and a surveillance role mediated by health care professionals known to the patient and carer would be a pragmatic approach to improving care.

National questionnaire survey on what influences doctors' decisions about admission to intensive care

OBJECTIVE

To determine what influences doctors' decisions about admission of patients to intensive care.

DESIGN

National questionnaire survey using eight clinical vignettes involving hypothetical patients.

SETTING

Switzerland.

PARTICIPANTS

402 Swiss doctors specialising in intensive care.

MAIN OUTCOME MEASURES

Rating of factors influencing decisions on admission and response to eight hypothetical clinical scenarios.

RESULTS

Of 381 doctors agreeing to participate, 232 (61%) returned questionnaires. Most rated as important or very important the prognosis of the underlying disease (82%) and of the acute illness (81%) and the patients' wishes (71%). Few considered important the socioeconomic circumstances of the patient (2%), religious beliefs (3%), and emotional state (6%). In the vignettes, underlying disease (cancer versus non-cancerous disease) was not associated with admission to intensive care, but four other factors were: patients' wishes (odds ratio 3.0, 95% confidence interval 2.0 to 4.6), "upbeat" personality (2.9, 1.9 to 4.4), younger age (1.5, 1.1 to 2.2), and a greater number of beds available in intensive care (1.8, 1.2 to 2.5).

CONCLUSIONS

Doctors' decisions to admit patients to intensive care are influenced by patients' wishes and ethically problematic non-medical factors such as a patient's personality or availability of beds. Patients with cancer are not discriminated against.

Terminal dyspnea and respiratory distress

Dyspnea is a subjective experience that can be reported by the patient. Respiratory distress is an observable corollary, and represents the physical or emotional suffering that results from the experience of dyspnea. Recognizing and understanding this subjective phenomenon poses a challenge to intensive care unit (ICU) clinicians when caring for the patient who is dying in the ICU. Dyspnea and cognitive impairment are highly prevalent in the terminally ill ICU patient. A Respiratory Distress Observation Model may provide a theoretical foundation for the assessment of this phenomenon that is grounded in emotional and autonomic domains of neurologic function. Treatment of dyspnea and respiratory distress relies on nonpharmacologic interventions and opioids and sedatives. As with pain, the treatment of dyspnea and respiratory distress relies on close evaluation of the patient and treatment to satisfactory effect. Empirical evidence suggests that quality care with control of distressing symptoms does not hasten death. Withholding opioids or sedatives in the face of unrelieved dyspnea or respiratory distress has no moral foundation.

Pain experienced by lung cancer patients: a review of prevalence, causes and pathophysiology

BACKGROUND

Lung cancer is one of the commonest cancers to cause pain, but little is known regarding the extent of this complex problem in these patients.

METHODS

Medline (1966-June 2002) and Cancerlit (1975-May 2002) were searched to identify studies of lung cancer patients' experience of pain, its prevalence, causes and underlying pathophysiology.

RESULTS

Thirty-two studies were identified. Patients were recruited from diverse populations, and the prevalence varied according to study setting. Pain affected 27% of outpatients (range 8-85%), and 76% of patients cared for by palliative care services (range 63-88%). Pain was caused by cancer in 73% (range 44-87%), and cancer treatment in 11% (range 5-17%). Nociceptive pain was the major pathophysiological subtype in lung cancer pain, but neuropathic pain accounted for 30% (range 25-32%) of cases.

CONCLUSIONS

The overall weighted mean pain prevalence of pain was 47% (range 6-100%). Cancer patients should be asked about pain at all stages of management. Those with pain should be investigated for disease progression and considered for referral for specialist management.

A concept analysis of palliative care in the United States

PURPOSE

The purpose of this analysis is to trace the evolution of the concept of palliative in the United States, explicate its meanings, and draw comparisons with other related concepts such as hospice care and terminal care.

METHODS

Rodgers' evolutionary method was used as an organizing framework for the concept analysis. Data were collected from a review of CINAHL, MEDLINE, CANCERLIT, PsycINFO and Sociological Abstracts databases using 'palliative care' and 'United States' as keywords. Articles written in the English language, with an abstract, published between 1965 and 2003 were considered. Data were synthesized to identify attributes, antecedents and consequences of palliative care.

FINDINGS

There has been a significant evolution in understanding of the palliative care concept in the United States over the last few decades, which has resulted in the emergence of new models of palliative care. Four attributes of the current palliative care concept were identified: (1) total, active and individualized patient care, (2) support for the family, (3) interdisciplinary teamwork and (4) effective communication. Results reinforce that cure and palliation are not mutually exclusive categories.

CONCLUSIONS

The scope of palliative care has evolved to include a wide range of patient populations who may not be appropriately termed 'dying' but for whom alleviation of suffering and improvement of quality of life may be very relevant goals. The ultimate success of the new models of palliative care will eventually rest upon the commitment of health professionals to recognize and integrate the changing concept of palliative care into everyday practice.

Chronic obstructive pulmonary disease in geriatric critical care

COPD is a progressive disorder that is punctuated in its later stages with acute exacerbations that present a risk for respiratory failure. COPD has a disproportionate impact on older patients. In the ICU, therapy is directed toward unloading fatigued respiratory muscles, treating airway infection, and prescribing bronchodilatory drugs. Most patients survive hospitalization in the ICU for an episode of respiratory failure. The severity of the underlying lung disease, however, underlies the poor outcomes of patients in terms of postdischarge survival and quality of life.

Patient perceptions of an outpatient palliative care intervention: "It had been on my mind before, but I did not know how to start talking about death..."

Little is known about whether introducing palliative care to seriously ill outpatients continuing to pursue treatment of their disease is acceptable or beneficial to patients. Intervention patients in a trial of outpatient palliative care consultation completed structured exit interviews as part of a qualitative study. Participants had advanced heart or lung disease or cancer, and a life expectancy between 1 to 5 years as estimated by their primary care physician (PCP). Thirty-five of 50 intervention patients (70%) completed the final interview. Twenty-one patients (60%) reported that the team uncovered previously undiagnosed medical problems, 12 patients (34.3%) reported decreased primary care visits, and 8 (22.9%) reported avoiding emergency department visits. Most patients reported improved satisfaction with family caregivers (85.7%), PCPs (80%), and the medical center (65.7%). Most patients (68.6%) would have wanted the intervention even earlier in the course of their illness. Seriously ill outpatients found palliative care acceptable and helpful, reporting increased satisfaction and decreased health care utilization.

Prevalence of sub-threshold depression in elderly patients with chronic obstructive pulmonary disease

OBJECTIVES

We hypothesized that COPD patients with sub-threshold depression would have levels of disability and impaired quality of life approaching that for major depression and significantly greater than for non-depressed COPD patients.

SETTING

A university teaching hospital

METHOD

137 outpatients (69 men), with a mean age of 73 years (range 60-89 years) with symptomatic irreversible, moderate to severe COPD were recruited. Subjects were interviewed using the Geriatric Mental State Schedule (GMS), a structured psychiatric interview schedule, along with its diagnostic algorithm AGECAT. A GMS/AGECAT score of 3 or more is indicative of a case-level of depression, a GMS/AGECAT score of 1-2 indicates sub-threshold depression and GMS/AGECAT of 0, no depression. Physical disability was measured by the Manchester Respiratory Activities of Daily Living questionnaire (MRADL) and quality of life was assessed by the Breathing Problems Questionnaire (BPQ).

RESULTS

Mean (SD) one second forced expiratory volume was 0.89 (0.33) litres. The prevalence of GMS/AGECAT case-level depression (>or= 3) was 57 cases (42%); of GMS/AGECAT sub-threshold depression (1-2) 34 (25%); and GMS/AGECAT non-depression (0) 46 (33%). Comparison of MRADL score in the three groups (mean, 95% confidence intervals) revealed [GMS >or= 3 = 9.9 (8.4 to 11.3) vs GMS = 1-2, 12.9 (11.2 to 14.4) vs GMS = 0, 15.6 (14 to 16.6) p < 0.0001]. BPQ scores (mean, 95% confidence intervals) showed [GMS >or= 3 = 54 (50 to 57) vs GMS = 1-2, 40 (36.3 to 44) GMS = 0, 33 (30.6 to 36.7) p < 0.0001]. There was no significant difference in FEV(1) between the three groups.

CONCLUSION

Sub-threshold depression accounted for 25% of the sample. In this study disability associated with sub-threshold depression in patients with COPD was intermediate to that associated with case-level depression and no with depression and significantly worse than in the latter group. Sub-threshold depression is associated with substantial morbidity in COPD.

Measuring the symptom experience of seriously ill cancer and noncancer hospitalized patients near the end of life with the memorial symptom assessment scale

The objectives of this study were twofold: (1) to explore and compare the symptom experience of seriously ill hospitalized cancer and noncancer patients near the end of life using the Memorial Symptom Assessment Scale (MSAS) and (2) to determine if the MSAS is a valid and useful measure of symptom distress for patients with noncancer conditions. This was a prospective cohort study of hospitalized patients with end-stage congestive heart disease, chronic pulmonary disease, cirrhosis, or metastatic cancer. Eligible patients were interviewed to ascertain symptom prevalence, severity and distress using the MSAS and levels of fatigue using the Piper Fatigue Scale (PFS). Sixty-six patients with metastatic cancer and 69 patients with end-stage disease were enrolled in the study. There was a significant difference in the prevalence of selected physical symptoms, but not psychological symptoms, between cancer and noncancer patients. There were no significant differences in symptom distress scores, a computed score of frequency, severity and distress, if the symptom was present. In both groups the principal components factor analysis with varimax rotation yielded one factor comprising psychological symptoms and a second factor comprising three subgroups of physical symptoms. Internal consistency was high for the psychological subscale (Cronbach alpha coefficients of 0.85 for the cancer group and 0.77 for the noncancer group) and for the physical subscale groupings, with coefficients ranging between 0.78 to 0.87. The symptom scores were significantly correlated with perceptions of fatigue. These findings show that both seriously ill cancer and noncancer patients experience symptom distress, and that the MSAS seems to be a reliable measure of symptom distress in noncancer patients, as well as with cancer patients.

Treatment of chronic obstructive pulmonary disease in older patients: a practical guide

Chronic obstructive pulmonary disease (COPD) is a common disability, largely encountered in the elderly population, in whom it causes significant morbidity and mortality. The general perception of health professionals is that COPD is often a self-inflicted disorder affecting the more socio-economically disadvantaged segment of the population with significant comorbidity. COPD is the least funded in terms of research in relation to illness burden compared with other chronic diseases. However, recently published guidelines of both the British Thoracic Society and the Global Initiative for Chronic Obstructive Lung Disease have highlighted best management strategies both of chronic symptoms and acute exacerbations in this patient group. The chronic management of COPD should, like asthma, involve a stepwise approach with smoking cessation being pivotal for all severities of COPD, regardless of patient age. The mainstay of therapeutic treatment remains regular bronchodilators, both beta(2)-adrenoreceptor agonists and anticholinergic agents. Current evidence suggests that long-acting beta(2)-adrenoreceptor agonists such as salmeterol and the new long-acting anticholinergic agent tiotropium bromide are more efficacious than their shorter acting equivalents such as salbutamol and ipratropium bromide in terms of bronchodilation, improved well-being and a reduction in acute exacerbation rates. Additionally since they are taken once or twice daily compliance should be improved. The role of long-term inhaled corticosteroids in the chronic management of COPD is contentious. Only those patients with COPD who have been shown to respond to a formal corticosteroid trial, preferably with a 2-week course of oral corticosteroid, should receive long-term inhaled corticosteroids. In the management of acute exacerbations in acidotic patients nasal ventilation is the treatment of choice in addition to conventional treatment with bronchodilators and oral corticosteroids. Antibacterials need not be prescribed universally in all exacerbations of COPD. Pulmonary rehabilitation classes either individually or in groups have been shown to be beneficial in the management of patients with COPD and their use in secondary care is to be encouraged. Most treatment modalities do not improve pulmonary function in patients with severe COPD. Therefore, pulmonary function including spirometry should be used to make the diagnosis of COPD but not as a monitor of efficacy of treatment. Assessment of severity of COPD and improvement with treatment modalities is best done with dynamic exercise testing such as 6-minute walk tests and incremental shuttle walk tests or with the administration of disease-specific physical disability and quality-of-life questionnaires. Most COPD research does not specifically target the older COPD patients and these patients may merit special consideration for their optimum assessment and management.

The last 2 years of life: functional trajectories of frail older people

OBJECTIVES

To characterize the functional trajectories during the last 2 years of life of patients with progressive frailty, with and without cognitive impairment, and to assess whether it was possible to identify discrete functional indicators that signal the end of life.

DESIGN

A retrospective analysis of functional trajectories during the last 24 months of life.

SETTING

Twelve demonstration sites of the Program of All-inclusive Care for the Elderly (PACE). PACE cares for frail older people who meet criteria for nursing home placement, with the goal of keeping the patient at home.

PARTICIPANTS

Nine hundred seventeen patients who died while enrolled in PACE.

MEASURES

At PACE entry and every 3 months thereafter, data were collected about the degree of dependence (none, partial, or full) in bathing, eating, and walking and the degree of incontinence (none, bladder, or bowel). Cognitive impairment was defined as six or more errors on the Short Portable Mental Status Questionnaire. To describe the end-of-life trajectories of patients, data were analyzed from observational windows of time, beginning with the patients' dates of death and extending backward in time to 24 months before death. Each analytical window was 3 months in duration. For each of the functional measures, the probability of functional deterioration in the last 2 years of life in patients with (64%) and without (36%) cognitive impairment was also compared.

RESULTS

The mean age at death was 84; 69% of patients were women. For patients with and without cognitive impairment, a prolonged, steady increase in the rates of functional dependence that were evident at least 1 year before death, rather than sudden increases in functional dependence shortly before death, characterized the functional trajectories. It was not possible for any of the four measures to detect a time point before death at which there was an abrupt decline in function likely to signal impending death. For each measure, patients with cognitive impairment declined earlier, were more likely than patients without cognitive impairment to have the maximal level of dependence in the 0- to 3-month window before death (e.g., 56% vs 30% for mobility, P <.001), and were more likely to decline in the 2 years before death (e.g., 56% vs 36% for mobility, P <.001).

CONCLUSION

Patients with advanced frailty, with or without cognitive impairment, have an end-of-life functional course marked by slowly progressive functional deterioration, with only a slight acceleration in the trajectory of functional loss as death approaches. Patients with cognitive impairment have particularly high rates of functional impairment at the time of death. These results suggest that end-of-life care systems that are targeted toward patients with functional trajectories clearly suggesting impending death (such as the Medicare hospice benefit) are poorly suited to older people dying with progressive frailty.

End-of-life care in patients with lung cancer

Evidence-based practice guidelines for end-of-life care for patients with lung cancer have been previously available only from the British health-care system. Currently in this setting, there has been increasing concern in attaining control of the physical, psychological, social, and spiritual distress of the patient and family. This American College of Chest Physicians'-sponsored multidisciplinary panel has generated recommendations for improving quality of life after examining the English-language literature for answers to some of the most important questions in end-of-life care. Communication between the doctor, patient, and family is central to the active total care of patients with disease that is not responsive to curative treatment. The advance care directive, which has been slowly evolving and is presently limited in application and often circumstantially ineffective, better protects patient autonomy. The problem-solving capability of the hospital ethics committee has been poorly utilized, often due to a lack of understanding of its composition and function. Cost considerations and a sense of futility have confused caregivers as to the potentially important role of the critical care specialist in this scenario. Symptomatic and supportive care provided in a timely and consistent fashion in the hospice environment, which treats the patient and family at home, has been increasingly used, and at this time is the best model for end-of-life care in the United States.

Lung cancer. Palliative care

The majority of patients who acquire lung cancer will have troublesome symptoms at some time during the course of their disease. Some of the symptoms are common to many types of cancers, while others are more often encountered with lung cancer than other primary sites. The most common symptoms are pain, dyspnea, and cough. This document will address the management of these symptoms, and it will also address the palliation of specific problems that are commonly seen in lung cancer: metastases to the brain, spinal cord, and bones; hemoptysis; tracheoesophageal fistula; and obstruction of the superior vena cava.

Life-sustaining treatments in patients who died of chronic congestive heart failure compared with metastatic cancer

INTRODUCTION

Life-sustaining treatments such as cardiopulmonary resuscitation, mechanical ventilation, vasopressors, and admission to critical care units, if used when recovery chance was remote, may unnecessarily cause discomfort and increase cost of care. Outcomes of these treatments in chronic, refractory congestive heart failure (CHF) and metastatic cancer patients were poor. Although both conditions were the leading causes of death, previous studies indicated that hospice utilization and do-not-resuscitate orders were less common in CHF patients. To date, the use of life-sustaining treatments in these patients and the influence of do-not-resuscitate orders remains unknown.

METHOD

We conducted a retrospective medical record review of the patients who died in our hospital in 1999 and had discharge diagnoses of CHF or cancer. Medical records were screened for seriously ill patients according to the modified SUPPORT criteria, which included patients with CHF functional class IV or ejection fraction of 20% or less at baseline and with metastatic cancer not receiving any curative treatments. Analyses were performed using SPSS, version 9.0.

RESULTS

There were 58 and 82 patients in CHF and cancer groups, respectively. CHF patients were older (78.8 vs. 67.3 yrs, p < .001) and stayed in the hospital longer (11.9 vs. 7.9 days, p = .014). The majority of patients in both groups received do-not-resuscitate orders before death (84% and 72%, respectively). CHF patients received do-not-resuscitate orders later than did cancer patients (6.7 vs. 2.8 days, p = .006). However, there was no significant difference in prevalence of do-not-resuscitate orders. All studied life-sustaining treatments were more common in CHF patients than in cancer patients. A subgroup analysis between CHF patients with do-not-resuscitate orders and those without do-not-resuscitate orders revealed cardiopulmonary resuscitation to be the only treatment less common in those with do-not-resuscitate orders.

CONCLUSIONS

Patients who died of chronic, refractory CHF received more life-sustaining treatments than did patients who died of metastatic cancer.

Predictive factors for suicidal ideation in patients with unresectable lung carcinoma

BACKGROUND

Despite serious concern over the suicidality of cancer patients in clinical oncology practice, few studies have addressed this issue. The purpose of the current study was to investigate the prevalence and predictive factors of suicidal ideation in patients with unresectable lung carcinoma in a follow-up setting.

METHODS

Patients with newly diagnosed unresectable nonsmall cell lung carcinoma participated in this study. Their suicidal ideation was assessed 6 months after disclosure of the cancer diagnosis. Predictive factors for suicidal ideation were investigated by assessing a broad range of biomedical and psychosocial factors between the time of disclosure and start of cancer therapy (baseline) and 6 months after disclosure of the cancer diagnosis (follow-up).

RESULTS

Although strong suicidal ideation was rare in this population, 13 (15%) of the 89 subjects who completed the baseline and follow-up ratings had some degree of suicidal ideation 6 months after disclosure of the cancer diagnosis. Univariate analysis revealed that significant predictive factors for suicidal ideation were pain at baseline, declining physical function, and the development of a depressive disorder. Multivariate analysis indicated that pain at baseline (odds ratio [OR] = 3.72, 95% confidence interval [CI] = 1.12-14.69, P = 0.04) and the development of a depressive disorder (OR =27.97, 95% CI = 5.18-214.14, P = 0.0003) were the final significant predictive factors.

CONCLUSIONS

Suicidal ideation among unresectable lung carcinoma patients should not be neglected because it is not rare. Comprehensive care consisting of at least earlier pain management and appropriate psychiatric intervention is indispensable to prevent subsequent suicidal ideation.

Patients' perspectives on physician skill in end-of-life care: differences between patients with COPD, cancer, and AIDS

OBJECTIVES

Patients' views of physician skill in providing end-of-life care may vary across different diseases, and understanding these differences will help physicians improve the quality of care they provide for patients at the end of life. The objective of this study was to examine the perspectives of patients with COPD, cancer, or AIDS regarding important aspects of physician skill in providing end-of-life care.

DESIGN

Qualitative study using focus groups and content analysis based on grounded theory.

SETTING

Outpatients from multiple medical settings in Seattle, WA.

PATIENTS

Eleven focus groups of 79 patients with three diseases: COPD (n = 24), AIDS (n = 36), or cancer (n = 19).

RESULTS

We identified, from the perspectives of patients, the important physician skills for high-quality end-of-life care. Remarkable similarities were found in the perspectives of patients with COPD, AIDS, and cancer, including the importance of emotional support, communication, and accessibility and continuity. However, each disease group identified a unique theme that was qualitatively more important to that group. For patients with COPD, the domain concerning physicians' ability to provide patient education stood out as qualitatively and quantitatively more important. Patients with COPD desired patient education in five content areas: diagnosis and disease process, treatment, prognosis, what dying might be like, and advance care planning. For patients with AIDS, the unique theme was pain control; for patients with cancer, the unique theme was maintaining hope despite a terminal diagnosis.

CONCLUSIONS

Patients with COPD, AIDS, and cancer demonstrated many similarities in their perspectives on important areas of physician skill in providing end-of-life care, but patients with each disease identified a specific area of end-of-life care that was uniquely important to them. Physicians and educators should target patients with COPD for efforts to improve patient education about their disease and about end-of-life care, especially in the areas defined above. Physicians caring for patients with advanced AIDS should discuss pain control at the end of life, and physicians caring for patients with cancer should be aware of many patients' desires to maintain hope. Physician understanding of these differences will provide insights that allow improvement in the quality of care.

Managing dyspnea and cough

Dyspnea, like pain, is a subjective experience that incorporates physical elements and affective components. Management of breathlessness in patients with cancer requires expertise that includes an understanding and assessment of the multidimensional components of the symptom, knowledge of the pathophysiologic mechanisms and clinical syndromes that are common in cancer, and familiarity with the indications and limitations of the available therapeutic approaches. Relief of breathlessness should be the goal of treatment at all stages of cancer. Good control of dyspnea will improve the patient's quality of life.

Can we do better in end-of-life care? The mixed management model and palliative care

The increasing duration of life from disease diagnosis to death in cancer and chronic non-malignant illnesses argues for a revised approach to end-of-life care that incorporates the principles of palliative care from an earlier stage (ie, a stage at which curative and/or life-prolonging treatments are still being provided). The provision of active treatment and comfort measures/death preparation in parallel has been called the "mixed management model" of end-of life care.

Photodynamic Therapy for Patients with Advanced Non–Small-Cell Carcinoma of the Lung

Patients with advanced non-small-cell lung carcinoma (NSCLC) have poor prognoses and experience negative sequelae of disease. Patients often suffer from dyspnea and/or hemoptysis, with overall pulmonary compromise. Patients with advanced, inoperable disease have limited options for treatment. This study summarizes our early experience and findings using photodynamic therapy (PDT) as an effective modality in the palliation of hemoptysis, dyspnea, and physical airway obstruction in cases of inoperable lung cancer. A retrospective review was conducted for the first 10 patients diagnosed with stage III/IV obstructive NSCLC who underwent PDT at our institution. Endobronchial lesions were identified by bronchoscopy. Treatments were initiated 48 hours after intravenous injection of 2 mg/kg of the photosensitizing agent porfimer sodium (Photofrin, QLT PhotoTherapeutics, Vancouver, BC). The porfimer sodium was then activated by illumination with a 630 nm wavelength light using a Coherent argon ion laser through a flexible bronchoscope. Repeated bronchoscopies were performed 1-3 days following initial PDT for evaluation and airway debridement. In 8 cases, a second treatment of PDT was administered within 72 hours of the first injection. One patient received a third treatment several months later. Three patients also received endobronchial stents after PDT. Overall, all 10 patients responded to PDT. Physical airway obstruction was reduced in all patients, with a noted improvement in bronchoscopic luminal diameter. Acute hemoptysis resolved in all 7 symptomatic patients. Median survival was 5.5 months post-PDT, while median survival postdiagnosis was 10.5 months. Three patients are alive at the time of this review at 5-21 months following therapy. Patients with unresectable late-stage NSCLC have few options for treatment. Our early experience with PDT indicates effective relief of hemoptysis, dyspnea, and airway obstruction and improves their quality of life.

Behavioral interventions for lung cancer-related breathlessness

PURPOSE

The purpose of this report is to present behavioral interventions to assist persons with lung cancer in the management of feelings of breathlessness and, thus, also to enhance their quality of life.

OVERVIEW

Breathlessness is a serious symptom that adversely affects the quality of life of persons with lung cancer. A review of the literature points to the value of exercises in assisting patients to breathe more effectively and to manage related anxiety. However, the professional literature frequently does not describe these basic interventions in enough detail to enable oncology professionals to learn them. Instructional materials, found in the popular wellness and self-help literature, are included in this article to more easily facilitate acquisition of these skills. Interventions described include exercises that enhance the use of the diaphragm when breathing and those that help to alter the breathing rhythm and to exhale more effectively.

CLINICAL IMPLICATIONS

All oncology professionals should be aware of the importance of breathlessness as a problem that diminishes the quality of life for patients with lung cancer. Addressing breathlessness through the use of psychosocially oriented behavioral interventions can act as an adjunct to the medical management of this debilitating symptom.
