Rethinking fundamental assumptions: SUPPORT's implications for future reform. Study to Understand Prognoses and Preferences and Risks of Treatment

The state of advance care planning: one decade after SUPPORT

The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT) was a landmark study regarding end-of-life decision making and advance care planning. Phase I of the study looked at the state of end of life in various hospitals, and phase II implemented a nurse-facilitated intervention designed to improve advance care planning, patient-physician communication, and the dying process. The observational phase found poor quality of care at the end of life and the intervention failed to improve the targeted outcomes. The negative findings brought public attention to the need to improve care for the dying and spawned a wealth of additional research on decision-making at the end of life. In the decade since SUPPORT, researchers have defined the attributes of a "good death," addressed the role of advance directives in advance care planning, and studied the use of surrogate decision-making at the end of life. This rekindled the discussion on advance care planning and challenged health care providers to design more flexible approaches to end of life care.

Integrating palliative and critical care: description of an intervention

A large proportion of deaths in the United States occur in the intensive care unit (ICU) or after a stay in the ICU, and there is evidence of problems in the quality of care these patients and their families receive. In an effort to respond to this problem, we developed a multifaceted, nurse-focused, quality improvement intervention that is based on self-efficacy theory applied to changing clinician behavior. We have called the intervention "Integrating Palliative and Critical Care." This five-component intervention includes: 1) critical care clinician education to increase knowledge and awareness of the principles and practice of palliative care in the ICU, 2) critical care clinician local champions to provide role modeling and promote attitudinal change concerning end-of-life care, 3) academic detailing of nurse and physician ICU directors to identify and address local barriers to improving end-of-life care in each ICU, 4) feedback of local quality improvement data, and 5) system supports including implementation of palliative care order forms, family information pamphlets, and other system supports for providing palliative care in the ICU. The goal of this report is to describe the conceptual model that led to the development of the intervention, and for each of the five components, we describe the theoretical and empirical support for each component, the content of the component, and the lessons we have learned in implementing the component. Future reports will need to examine the ability of the interventions to improve outcomes of palliative care in the ICU.

Assessment is not enough: a randomized controlled trial of the effects of HRQL assessment on quality of life and satisfaction in oncology clinical practice

The potential benefits of health-related quality of life (HRQL) assessment in oncology clinical practice include better detection of problems, enhanced disease and treatment monitoring and improved care. However, few empirical studies have investigated the effects of incorporating such assessments into routine clinical care. Recent randomized studies have reported improved detection of and communication about patients' concerns, but few have found effects on patient HRQL or satisfaction. This study examined whether offering interpretive assistance of HRQL results would improve these patient outcomes. Two hundred and thirteen participants with metastatic breast, lung or colorectal cancer were randomly assigned to one of three conditions: usual care; HRQL assessment or HRQL assessment followed by a structured interview and discussion. Interviews about patients' assessment responses were conducted by a research nurse, who then presented HRQL information to the treating nurse. HRQL and treatment satisfaction outcomes were assessed at 3 and 6 months. No significant differences were found between study conditions in HRQL or satisfaction. Results suggest that routine HRQL assessment, even with description of results, is insufficient to improve patient HRQL and satisfaction. It is suggested that positive effects may require supplementing assessment results with specific suggestions for clinical management changes.

Avoiding iatrogenic harm to patient and family while discussing goals of care near the end of life

BACKGROUND

Treatment of suffering is a core mission of medicine. Communication about treatment planning with the patient and family, called the goals of care discussion, offers the opportunity to provide effective relief. Such communication is particularly important near the end of life, because many medical decisions are determined then by emotional considerations and personal values.

OBJECTIVE

To define common unintended clinician behaviors, which impair discussion about goals of care near the end of life. To discuss the relationship between: (1) the medical decision-making responsibilities of patient and family, (2) clinician communication, (3) iatrogenic suffering, (4) the impact on medical decision-making, and (5) patient and family outcomes.

DESIGN

Thematic literature review.

RESULTS

The authors discuss how omission of the integral emotional and social elements of the goals of care discussion are reflected in five unintended clinician behaviors, each of which may impair medical decision-making and unknowingly induce patient and family suffering. We posit that such impaired decision-making and suffering may contribute to demands for ineffective, life-sustaining interventions made by the patient and family or, conversely, to requests for hastened death.

CONCLUSIONS

Understanding the challenges in the discussion about goals of care near the end of life will facilitate the development of more effective approaches to communication and shared decision-making. The authors hypothesize how decreased suffering through improved communication should diminish the occurrence of depression, anxiety disorders, and complicated grief in the patient and survivors, potentially improving medical outcomes. Proposed experiments to test this hypothesis will address important public health goals.

Challenges to end of life care in the acute hospital setting

BACKGROUND

Research exploring patients' care and treatment preferences at the end of life (EOL) suggests they prefer comfort more than life-extension, wish to participate in decision-making, and wish to die at home. Despite these preferences, the place of death for many patients is the acute hospital, where EOL interventions are reported to be inappropriately invasive and aggressive.

AIM

This paper discusses the challenges to appropriate EOL care in acute hospitals in the UK, highlighting how this setting contributes to the patients' and families' care and treatment requirements being excluded from decision-making.

METHODS

Twenty-nine cancer nurse specialists from five hospitals participated in a grounded theory study, using observation and semi-structured interviews. Data were collected and analysed concurrently using the constant comparative method.

RESULTS

EOL interventions in the acute setting were driven by a preoccupation with treatment, routine practice and negative perceptions of palliative care. All these factors shaped clinical decision-making and prevented patients and their families from fully participating in clinical decision-making at the EOL.

Old age, life extension, and the character of medical choice

OBJECTIVES

This qualitative, ethnographic study explores the character and extent of medical choice for life-extending procedures on older adults. It examines the sociomedical features of treatment that shape health care provider understandings of the nature of choice, and it illustrates the effects of treatment patterns on patients' perspectives of their options for life extension.

METHODS

By using participant observation in outpatient clinics and face-to-face interviews, we spoke with a convenience sample of 38 health professionals and 132 patients aged 70 or older who had undergone life-extending medical procedures. We asked providers and patients open-ended questions about their understandings of medical choice for cardiac procedures, dialysis, and kidney transplant.

RESULTS

Neither patients nor health professionals made choices about the start or continuation of life-extending interventions that were uninformed by the routine pathways of treatment; the pressures of the technological imperative; or the growing normalization, ease, and safety of treating ever older patients. We found a difference among cardiac, dialysis, and transplant procedures regarding the locus of responsibility for maintaining and extending life.

DISCUSSION

Provider and patient practices together reveal how the standard use of medical procedures at ever older ages trumps patient-initiated decision making.

Managed death in a PACE: pathways in present and advance directives

OBJECTIVES

To test the effect of an innovative method of documenting present and advance health care wishes on the rates of completion and the qualitative choices of health care wishes.

DESIGN

Interventional prospective cohort (pre- and post-).

SETTING

Program for All-inclusive Care of the Elderly (PACE) site in St. Louis, MO.

PARTICIPANTS

Enrolled PACE participants.

INTERVENTION

A documentation tool that captures both present and advance directives in a framework of "pathways," blending goals of care with typical procedure-oriented directives.

MEASUREMENTS

Data from medical records to calculate rates of health care wishes (HCW) completion, proportions of qualitative choices, and compliance with wishes at death.

RESULTS

Baseline prevalences of present directives (PD) and advance directives (AD) were 77% and 36%, respectively, while Do Not Resuscitate (DNR) wishes were documented in 48% of PD and 26% of AD. After implementation of the Pathways Tool, completion rates increased to 99% for both PD and AD. Documented DNR wishes decreased to 38% of PD and increased to 66% of AD. Qualitative choices for care (Longevity vs Function vs Palliation) changed toward a palliation pathway for AD (from 9% to 53%). The rate of dying at home increased from 24% to 65%. Compliance with end-of-life wishes increased from 72% to 96%. These are statistically significant.

CONCLUSION

Introduction of a novel pathways method of documenting HCW in a PACE site was associated with increased completion, preferences toward less invasive levels of care at life's end, and increased compliance with participants' wishes and deaths at home. Future research to validate the methodology employed in this intervention should be conducted in other long-term care settings.

Progressive disease in patients with cancer presenting to an emergency room with acute symptoms predicts short-term mortality

GOALS

Patients with symptomatic, advanced cancer continue to be referred late or not at all for hospice or palliative care. We conducted a retrospective cohort study to determine whether evidence of cancer progression is an independent predictor of short-term mortality in acutely symptomatic cancer patients.

PATIENTS AND METHODS

We reviewed the records of 396 patients who visited the emergency center at a comprehensive cancer center in January 2000. Records were reviewed for clinical characteristics, including symptoms, type and extent of cancer, and whether the patient's cancer was stable or progressing (uncontrolled) at the time of the emergency center visit. Cox regression analysis was used to assess survival at 90 and 180 days, after controlling for patient characteristics.

MAIN RESULTS

Patients who died within 14, 90, or 180 days were more likely to have disease progression than those who did not. Dyspnea on emergency center presentation and disease progression were independent predictors of death within 90 or 180 days, after controlling for patient age, symptoms, signs, and the presence of metastases. The odds ratios for death within 90 and 180 days were 3.97 and 4.34, respectively (95% confidence intervals: 1.44, 10.94 and 1.87, 10.09).

CONCLUSION

Cancer disease progression is a clinical measure of increased risk of short-term mortality in acutely symptomatic cancer patients. Future studies should examine whether the use of this characteristic enhances identification of patients who could benefit from timely referral to hospice or palliative care. Symptomatic cancer patients presenting to a cancer center emergency room were more likely to die within 14, 90, or 180 days if they had evidence of recent progression of their cancer. Among patients with disease progression, 47% died within 90 days and 61% within 180 days.

Interventions to Improve Care during Withdrawal of Life-Sustaining Treatments

Withdrawal of life-sustaining therapies is a common occurrence in the intensive care unit (ICU) setting and also occurs in other hospital settings, long-term care facilities, and even at home. Many studies have documented dramatic geographic variations in the prevalence of withdrawal of life-sustaining therapies, and some evidence suggests this variation may be driven more by physician attitudes and biases than by factors such as patient preferences or cultural differences. A number of studies of interventions in the ICU setting have provided some evidence that withdrawal of life-sustaining therapies is a process of care that can be improved. The interventions have included routine ethics or palliative care consultations, routine family conferences, and standardized order protocol for withdrawal of life support. For some of the interventions, for example, ethics consultations or palliative care consultations, the precise mechanisms by which the process of care is improved are not clear. Furthermore, many of these studies have used surrogate outcomes for quality, such as ICU length of stay. Emerging research suggests more direct outcome measures may be useful, including family satisfaction with care and assessments of the quality of dying. Despite these relative limitations, these studies provide convincing evidence that withdrawal of life-sustaining therapy is a process of care that presents opportunities for quality improvement and that interventions are successful at improving this care. Further research is needed to identify and test the most appropriate and responsive outcome measures and to identify the most effective and cost-effective interventions.

Becky's legacy: more lessons

In this commentary on Werth's (this issue) article, the author attempts to continue the work of "meaning making" by describing 10 lessons that were evident to him, based on 25 years of experience as an end-of-life researcher and clinician. He highlights the impact of stress, the importance of communication, the idiosyncratic definition of a "good death," the role of patient-centered care, the power of self-efficacy, the need to integrate theory and experience, the use of interdisciplinary teams, the impact of altruism and having a sense of purpose, the need to listen, and the healing effects of communicating about loss.

Predictors of social service staff involvement in selected palliative care tasks in nursing homes: an exploratory model

Little research has been conducted on nursing home social service staff and end-of-life care in nursing homes. To address this gap, a cross-sectional study on end-of-life issues for people with dementia in nursing homes was conducted in New York State, in which 138 nursing home social service staff participated. This exploratory study examined issues such as perceived confidence, perceived influence, and demographic variables in relation to self-reported frequency of tasks related to palliative care of nursing home residents with dementia. Results showed that participants in this survey who discussed specific treatment issues during advance directive discussions perceived themselves to have higher degrees of influence in their respective facilities, were directors or managers of their departments, and were more likely to engage in tasks related to palliative care.

Tube feeding, antibiotics, and hospitalization of nursing home residents with end-stage dementia: Perceptions of key medical decision-makers

This article discusses the literature supporting the limited use of tube feeding, antibiotics, and hospital transfers of nursing home residents with end-stage dementia. This article also presents the findings of a study that queried 138 nursing home social service staff members in New York State regarding positions taken by key medical decision makers regarding tube feeding, antibiotic use, and hospitalization of nursing home residents with end-stage dementia. Results are discussed in the context of positions taken by experts in palliative and dementia care. According to social service staff perceptions, the majority of these key decision-makers (e.g., administrators, directors of nursing, and medical directors) take positions inconsistent with palliative care experts. Instead, a majority of them were perceived as more likely to encourage tube feeding, antibiotics, and hospitalization of nursing home residents with end-stage dementia. These findings indicate a strong need for educating administrative staff in state-of-the-art care of residents with end-stage dementia.

Three principles to improve clinician communication for advance care planning: overcoming emotional, cognitive, and skill barriers

BACKGROUND

Medical care of patients with life limiting illness remains fraught with serious deficiencies, including inadequate advance care planning, delayed hospice referral, and continued delivery of aggressive treatment that is overtly counter to patients' preferences.

OBJECTIVE

This paper describes clinicians' emotional, cognitive, and skill barriers to shared decision-making with seriously ill patients and their loved ones.

DESIGN

Thematic literature review.

RESULTS

Based on a literature review, as well as clinical and educational experience, we articulate three principles to address these barriers and guide future professional communication training for advance care planning.

CONCLUSIONS

We argue that these barriers must be overcome before deficiencies in end-of-life care can be fully ameliorated.

Patients' understanding of advance directives and cardiopulmonary resuscitation

OBJECTIVE

To describe understanding of end-of-life issues and compare characteristics of patients with and without advance directives.

SETTING

A 325-bed community teaching hospital.

MEASUREMENTS

Questionnaires were administered to all patients admitted to the medical-surgical wards.

RESULTS

Of 755 patients admitted during the study period, 264 patients participated in the study, and 82 (31%) had living wills. Patients with living wills were more likely to be white, Protestant, and highly educated. Most (76%) created them with a lawyer or family member, whereas only 7% involved physicians. Although these patients were able to identify some components of cardiopulmonary resuscitation (CPR), few (19%) understood the prognosis after CPR. After explaining CPR, 37% of those with living wills did not want it, which was not stated in their directive or hospital record. If life-sustaining therapies were already started, 39% of these patients stated that they would not want CPR or mechanical ventilation if the likelihood of recovery was < or =10%. Patients without living wills either had not heard (18%) or did not know enough (51%) about them. After education, 5% did not want CPR, and 32% would terminate life-sustaining therapies if the likelihood of recovery was < or =10%. Seventy percent of these patients expressed interest in creating a living will.

CONCLUSIONS

Patients with living wills understand poorly "life-sustaining therapies" and the implications of their advance directives. Most fail to involve physicians in creating directives. A significant number of those without living wills have end-of-life wishes that could be addressed by and appear open to the idea of creating advance directives.

Nursing home social worker skills and end-of-life planning

Little empirical information exists on nursing home social worker's involvement in advance care planning and end-of-life decision- making with nursing home residents and their family members. The purpose of this exploratory study was twofold: (1) to identify the frequency of skills associated with advance care planning that social workers use, and (2) to explore the factor structure of the scale used in the study. Results from 138 nursing home social worker respondents from New York State showed high frequency of advance directive discussions, care planning, and conflict resolution with families. The instrument factors clustered around administrative duties, and grief issues. There was substantial interest in continuing education in grief counseling with families.

Preferences in end-of-life care of older persons: after-death interviews with proxy respondents

This population-based study employing after-death interviews with proxies describes older persons' preferences regarding medical care at the end of life. Interviews were held with 270 proxy respondents of 342 deceased persons (age range 59-91) in the Netherlands, The deceased were respondents to the Longitudinal Aging Study Amsterdam. The prevalence of advance directives (ADs), preferences for medical decisions at the end of life (i.e. withholding treatment, physician-assisted suicide euthanasia) and preferences about the focus of treatment in the last week of life (i.e. comfort care versus extending life) were examined. Written ADs were present in 14% of the sample. A quarter had designated a surrogate decision-maker. Co-morbidity and perceived self-efficacy (PSE) were positively associated with ADs. About half the sample had expressed a preference in favour or against one or more medical decisions at the end of life. Predictors positively associated with expressing a preference were co-morbidity, dying from cancer, and PSE. Being religious was negatively associated with expressing a preference. The knowledge of the proxy regarding the older person's preference for the focus of treatment was dependent on the patient's symptom burden as perceived by the proxy. The majority of older persons had died without either an AD, or having expressed preferences for end-of-life care. Stimulating the formulation of ADs may help professionals who work with older people to understand these preferences better, especially in the case of non-cancer patients and those with low PSE.

An empirical analysis of the decision-making of limiting life-sustaining treatment for patients with advanced chronic obstructive pulmonary disease in Hong Kong, China

OBJECTIVES

To understand the prognostic and quality-of-life considerations surrounding life-sustaining treatment decisions for patients with advanced chronic obstructive pulmonary disease (COPD) in Hong Kong China.

METHODS

A documentary review of 49 COPD patients and 19 patient case studies from the medical departments of 2 hospitals were undertaken to examine the practices of DNI decision-making (do not perform mechanical ventilation and cardiopulmonary resuscitation). Statistical, event, and thematic analyses were conducted to delineate the prognostic and quality-of-life factors that shaped the not for intubation and mechanical ventilation (DNI) decisions.

RESULTS

Three major treatment-limiting decision-making patterns existed in practice: 1) Patient-initiated and shared decision-making with physician (n = 14); 2) Physician-initiated and shared decision-making with the patient/family members (n = 24); and 3) Physician-initiated DNI decision-making with patient family, but without patient participation due to mental incapacity (n = 11). Prognostic considerations include physiological parameters, performance status, concomitant diseases, therapeutic regimens, and the utilization of medical services. Three major themes were delineated regarding the way in which the patients evaluated their life quality in the context of DNI status. They are prognostic awareness, illness burdens, and existential concerns.

DISCUSSION

A decision-making framework used by patients/families/physicians to limit life-sustaining treatments in patients with advanced COPD is delineated. Observations regarding how treatment limiting decision-making for patients with advanced chronic illnesses can be improved in Hong Kong are discussed.

"Getting Everyone on the Same Page": Nursing Home Physicians' Perspectives on End-of-Life Care

PURPOSE

To improve understanding of nursing home physicians' perspectives regarding end-of-life care, and to suggest directions for further research.

METHODS

An exploratory qualitative design based on interviews of 12 nursing home physicians, 10 of whom were medical directors. Medical students served as interviewers.

SAMPLE

A purposeful sampling strategy yielded interviews with 12 physicians. The sample was selected based on "intensity sampling," which seeks information-rich but not extreme cases. Ten of the 12 physicians were nursing home medical directors; all respondents practiced at least 4 years part-time or full-time in a nursing home setting. Respondents varied by age, gender, urban/rural location, and fellowship training (half the sample had completed a geriatrics fellowship). Seven physicians were affiliated with an academic medical center.

RESULTS

Four themes were identified in the analysis of the 12 interview transcripts: extensive familiarity with dying; consensus is integral to good end-of-life care; obstacles can interfere with consensus; and advance directives set the stage for conversations about end-of-life care. The importance of consensus, both in terms of prognosis and in developing a palliative care plan, emerged as the major finding.

CONCLUSIONS

For the 12 physicians in this study consensus about the resident's status and an appropriate care plan are important features of good end-of-life care. Further research is needed to determine if other members of the health care team (i.e., residents, family members, nursing staff, social worker, etc.) also value consensus highly. It will be important to determine what barriers to consensus other team members identify. Based on the understanding generated from this study, a refinement of the general Education for Physicians on End-of-Life Care (EPEC) model describing the relationship between curative and palliative care is proposed for nursing homes. The refinement underscores the points at which the team might consider revisiting consensus about the resident's status and care plan.

Evaluation of a standardized order form for the withdrawal of life support in the intensive care unit

OBJECTIVE

The intensive care unit remains a setting where death is common, and a large proportion of these deaths are preceded by withdrawal of life support. We describe a quality improvement project implementing and evaluating a "withdrawal of life support order form" to improve quality of end-of-life care in the intensive care unit.

DESIGN

Before-after evaluation.

SETTING

County-owned, university-operated, tertiary, level I trauma center.

SUBJECTS

Subjects were 143 nurses and 61 physicians.

INTERVENTIONS

We conducted a before-after evaluation of the order form's implementation. The order form has sections on preparations, sedation/analgesia, withdrawal of mechanical ventilation, and the principles of life support withdrawal. To evaluate the form, we surveyed intensive care unit clinicians regarding satisfaction with the form, measured nurse-assessed quality of dying and death with a 14-item survey (scored 0 for worst possible death to 100 for best possible), and performed chart review to assess narcotic and benzodiazepine use and time from ventilator withdrawal to death.

MEASUREMENTS AND MAIN RESULTS

We surveyed 143 nurses and 61 physicians about satisfaction with the form. Among nurses reporting that the form was used (n = 73), most (84%) reported that the order form was helpful and they were most satisfied with the sedation and mechanical ventilation sections. Almost all physicians found the form helpful (95%), and > 70% of physicians found three of the four sections helpful (sedation, mechanical ventilation, and preparations). We obtained quality of dying and death scores for 41 patient deaths before and 76 deaths after the intervention. These scores did not significantly change (mean preintervention score, 78.3; mean postintervention score, 74.2; p = .54) before and after the intervention. Total doses of narcotics and benzodiazepines increased after implementation of the order form in the hour before ventilator withdrawal, the hour after ventilator withdrawal, and the hour before death (p < or = .03). There was no change in the median time from ventilator withdrawal to death (preintervention 37 mins, postintervention 39 mins; p = .49).

CONCLUSIONS

Nurses and physicians found the withdrawal of life support order form helpful. The order form did not improve nurses' assessment of patients' dying experience. Medications for sedation increased during the postorder form period without evidence of significantly hastening death. Although the order form was helpful to clinicians and changed medication delivery, demonstrating clear improvements in quality of dying may require larger sample sizes, more sensitive measures, or more effective interventions.

Tube feeding in advanced Alzheimer's disease: when language misleads

For much of the late 20th century, feeding tubes were often considered essential in the treatment of people with advanced Alzheimer's disease (AD) who developed swallowing or eating problems. Increasingly, the use of feeding tubes (i.e., percutaneous endoscopic gastrostomy or PEG tubes), has been challenged by empirical research, which has not supported the rationales provided for this intervention. The purpose of this commentary is to explain why healthcare providers, in light of empirical evidence, should refrain from using the terms "life-sustaining" or "life-prolonging" when discussing tube feeding with older adults, their family members, or other surrogate decision-makers.

Improving care for patients dying in the intensive care unit

It is impossible for ICU clinicians to avoid caring for dying patients and their families. For many, this is an extremely rewarding aspect of their clinical practice. There is ample evidence that there is room to improve the care of patients who are near death in the ICU. Despite the considerable holes in our knowledge about optimal care of dying critically ill patients, there is considerable agreement on the general principles of caring for these patients and about how to measure the outcomes of palliative care in the ICU. Practical approaches to improving the quality of end-of-life care exist and should be implemented.

Results of a clinical trial on care improvement for the critically ill

OBJECTIVE

To develop, deploy, and evaluate an intervention designed to identify and mitigate conflict in decision making in the intensive care unit.

DESIGN

Nonrandomized, controlled trial.

SETTING

Seven intensive care units at four Boston teaching hospitals.

PATIENTS

A total of 1,752 critically ill patients, including 873 study cases analyzed here.

INTERVENTION

Social workers interviewed families of patients deemed at high risk for decisional conflict and provided feedback to the clinical team, who then implemented measures to address the problems identified.

MEASUREMENTS AND MAIN RESULTS

Patient or surrogate satisfaction with intensive care unit care and the probability of choosing a specific plan for treatment in the intensive care unit was studied. Inclusion criteria identified 873 patients at risk for decisional conflict. Thirty-nine percent of the patients in the intervention phase of the study (172 patients) received the intervention. In multivariate analyses, receiving the intervention significantly increased the likelihood of deciding to forgo resuscitation (odds ratio [OR] = 1.81, p =.017), the likelihood of choosing a treatment plan for comfort-care only (OR = 1.94, p =.018), and the likelihood of choosing an aggressive-care treatment plan (OR = 2.30, p =.002). Receiving the intervention did not significantly affect overall satisfaction with the care provided (OR = 0.68, p =.14), satisfaction with the amount of information provided (OR = 0.86, p =.44), or satisfaction with the degree of involvement in decision making (OR = 0.84, p =.54).

CONCLUSIONS

Although there was no impact on patient or surrogate satisfaction with care provided in the intensive care unit, the intervention did facilitate deliberative decision making in cases deemed at high risk for conflict. The lessons learned from the experience with this intervention should be helpful in ongoing efforts to improve care and to achieve outcomes desired by critically ill patients, their families, and critical care clinicians.

Changes in the use of do-not-resuscitate orders after implementation of the Patient Self-Determination Act

OBJECTIVE

To determine changes in the use of do-not-resuscitate (DNR) orders and mortality rates following a DNR order after the Patient Self-determination Act (PSDA) was implemented in December 1991.

DESIGN

Time-series.

SETTING

Twenty-nine hospitals in Northeast Ohio.

PATIENTS/PARTICIPANTS

Medicare patients (N = 91,539) hospitalized with myocardial infarction, heart failure, gastrointestinal hemorrhage, chronic obstructive pulmonary disease, pneumonia, or stroke.

MEASUREMENTS AND MAIN RESULTS

The use of "early" (first 2 hospital days) and "late" DNR orders was determined from chart abstractions. Deaths within 30 days after a DNR order were identified from Medicare Provider Analysis and Review files. Risk-adjusted rates of early DNR orders increased by 34% to 66% between 1991 and 1992 for 4 of the 6 conditions and then remained flat or declined slightly between 1992 and 1997. Use of late DNR orders declined by 29% to 53% for 4 of the 6 conditions between 1991 and 1997. Risk-adjusted mortality during the 30 days after a DNR order was written did not change between 1991 and 1997 for 5 conditions, but risk-adjusted mortality increased by 21% and 25% for stroke patients with early DNR and late DNR orders, respectively.

CONCLUSIONS

Overall use of DNR orders changed relatively little after passage of the PSDA, because the increase in the use of early DNR orders between 1991 and 1992 was counteracted by decreasing use of late DNR orders. Risk-adjusted mortality rates after a DNR order generally remained stable, suggesting that there were no dramatic changes in quality of care or aggressiveness of care for patients with DNR orders. However, the increasing mortality for stroke patients warrants further examination.

Time for non-cancer

At the European Association of Palliative Care congress (The Hague, April 2–5, 2003) it was clear that most of the delegates were talking about cancer. Palliative care in non-malignant disease is not yet a major priority in most European countries, although there are hopeful signs. First, those researchers and practitioners who presented studies on heart failure, respiratory diseases and renal failure were paid great interest by other delegates. Second, the American delegates made the application of palliative care to non-malignant diseases sound very straightforward. Although, there is considerable evidence that end-of-life care in America remains far from ideal (Lynn et al, 1997), it does seem that the services are applied equitably, rather than for one diagnostic group (cancer) as they are in much of Europe.

Beyond ethical dilemmas: improving the quality of end-of-life care in the intensive care unit

Consensus guidelines on providing optimal end-of-life care in the intensive care unit (ICU) are important tools. However, despite 30 years of ethical discourse and consensus on many of the principles that guide end-of-life care in the ICU, care remains inadequate. Although consensus on the most challenging ethical aspects of some cases will remain elusive, this need not deter clinicians from engaging in practical quality improvement, best practice, and educational interventions to provide compassionate care to all critically ill patients, including those who ultimately die.

Physicians' interactions with health care teams and systems in the care of dying patients: perspectives of dying patients, family members, and health care professionals

This study investigated the specific physician skills required to interact with health care systems in order to provide high quality care at the end of life. We used focus groups of patients with terminal diseases, family members, nurses and social workers from hospice or acute care settings, and physicians. We performed content analysis based on grounded theory. Groups were interviewed. Two domains were found related to physician interactions with health care systems: 1) access and continuity, and 2) team communication and coordination. Components of these domains most frequently mentioned included taking as much time as needed with the patient, accessibility, and respect shown in working with health team members. This study highlights the need for both physicians and health care systems to improve accessibility for patients and families and increase coordination of efforts between health care team members when working with dying patients and their families.

Ethical issues in the critically ill patient

Ethical issues have emerged in recent years as a significant component of care in the critically ill patient. Recently, the primary emphasis has been directed to care at the end-of-life. The factor that has been identified as the most important to patients and families and the one that is accomplished the least often is successful communication with the physicians. When communication does not take place or is inadequate physicians are left to try to determine what their patient's wishes would have been regarding end-of-life decisions. This leads to tremendous potential for conflict between the physician and the family, as the patients are often incapable of participating in any discussion regarding end-of-life care. Advance planning on the part of the patient in terms of making their wishes known and education of the health care professionals is essential in promoting effective communication, thereby avoiding conflict in these difficult end-of-life decisions.

Discussion of death and dying in surgical textbooks

BACKGROUND

Quality end-of-life care is an increasing concern for the public and the medical profession. Surgical textbooks could serve as an important educational and reference resource to improve this care.

METHODS

Four general surgical textbooks were scored for helpful information on death and dying for eight surgical diseases. For each disease, nine content domains related to care of the dying patient were evaluated. Three texts included a chapter on cancer that was evaluated separately.

RESULTS

Disease epidemiology, prognosis/prevention, progression, and medical interventions were generally well discussed in all textbooks. However, little helpful information was provided with regards to breaking bad news/advanced care planning, mode of death, treatment decision-making, effect on family/surgeon, and symptom management. Cancer chapters also addressed only a few of these concerns.

CONCLUSION

Death and the dying patient are sufficiently frequent in surgical practice that it would be appropriate to increase the amount of information provided.

Role of Ethics Committees, Ethics Networks, and Ethics Centers in Improving End-of-Life Care

This article chronicles the work of Midwest Bioethics Center, several community-state partnerships, and other local and national initiatives to determine their proper role and appropriate contribution. Professional education and development, institutional reform, and community engagement are areas of concern because ethics committees, networks, and centers sponsor workshops and conferences on palliative care for healthcare professionals, hold public forums, develop advance care planning projects, and provide expertise to legislators and other policymakers. The leading edge of the work being done by ethics committees, networks, and centers appears to be using continuous quality improvement methods, specifically the development of quality indicators, to promote accountability in end-of-life care reform efforts. This work is something that ethics committees can and should take on.

Advance care planning: pitfalls, progress, promise

We now have a decade of experience with advance directives since the Patient Self-Determination Act was signed into law in November 1990. With few exceptions, empirical studies have yielded disappointing results. Advance directives are recorded by medical personnel more often but are not completed by patients more frequently. The process of recording them does not enhance patient-physician communication. When available, advance directives do not change care or reduce hospital resources. The most ambitious study of advance care planning, the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments, failed to show any change in outcomes after an extensive intervention. Investigators have attempted to identify the reasons why the optimism about the Patient Self-Determination Act has not been realized. Many interventions to facilitate advance care planning were focused on specific treatment decisions. Recent research suggests that preferences for care are not fixed but emerge in a clinical context from a process of discussion and feedback within the network of the patient's most important relationships. Clinical trials emphasizing this approach have been successful. The approach that emphasizes communication, building trust over time, and working within the patient's most important relationships offers a hopeful model for clinicians working in intensive care units.

Communication and decision-making in seriously ill patients: findings of the SUPPORT project. The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments

OBJECTIVES

The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) represents one of the largest and most comprehensive efforts to describe patient preferences in seriously ill patients, and to evaluate how effectively patient preferences are communicated. Our objective was to review findings from SUPPORT describing the communication of seriously ill patients' preferences for end-of-life care.

METHODS

We identified published reports from SUPPORT describing patient preferences and the communication of those preferences. We abstracted findings that addressed each of the following questions: What patient characteristics predict patient preferences for end of life care? How well do physicians, nurses, and surrogates understand their patients' preferences, and what variables are correlated with this understanding? Does increasing the documentation of existing advance directives result in care more consistent with patients' preferences?

RESULTS

Patients who are older, have cancer, are women, believe their prognoses are poor, and are more dependent in ADL function are less likely to want CPR. However, there is considerable variability and geographic variation in these preferences. Physician, nurse, and surrogate understanding of their patient's preferences is only moderately better than chance. Most patients do not discuss their preferences with their physicians, and only about half of patients who do not wish to receive CPR receive DNR orders. Factors other than the patients' preferences and prognoses, including the patient's age, the physician's specialty, and the geographic site of care were strong determinants of whether DNR orders were written. In SUPPORT patients, there was no evidence that increasing the rates of documentation of advance directives results in care that is more consistent with patients' preferences.

CONCLUSIONS

SUPPORT documents that physicians and surrogates are often unaware of seriously ill patients' preferences. The care provided to patients is often not consistent with their preferences and is often associated with factors other than preferences or prognoses. Improving these deficiencies in end-of-life care may require systematic change rather than simple interventions.

Ineffectiveness of the SUPPORT intervention: review of explanations

BACKGROUND

The aim of the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments -- SUPPORT -- was to improve the care of seriously ill patients by improving decision-making for patients with life-threatening illnesses. Several theories have been proposed to explain why the SUPPORT intervention was unsuccessful at improving outcomes.

OBJECTIVE

To review and discuss explanations offered by others regarding why the SUPPORT intervention failed to have a discernible impact on its prespecified outcome measures.

DESIGN

A descriptive review of published articles and book chapters, with synthesis of data-based and conceptual insights.

METHODS

The Medline, Bioethicsline, and Ethx databases were searched for citations to SUPPORT articles between 1994 and the end of 1998. This search was supplemented by other published materials that had come to the authors' attention.

RESULTS

The critiques and explanations regarding the reasons the SUPPORT intervention did not improve outcomes were catalogued and organized into 11 major categories, the first 10 of which are explored in the present study: (1) the inception cohort was biased against an effect of the intervention, (2) the intervention was not implemented as designed, (3) the intervention failed because nurses were too readily ignored, (4) the intervention was too polite, (5) the intervention presented information ineffectively, (6) the intervention did not focus on primary care physicians, (7) the intervention falsely dichotomized do not resuscitate (DNR) decisions, (8) the intervention needed more years on site or an earlier start with each patient, (9) the intervention required more appropriate outcome measures, (10) the intervention was irrelevant because usual care is not seriously flawed, (11) the conceptual model behind SUPPORT was fundamentally flawed in aiming to improve individual, patient-level decision-making as the way to improve seriously ill, hospitalized patients' experiences.

CONCLUSIONS

Although some of the critiques were found to raise important concerns, we conclude in each case that the explanation offered is inadequate to explain the failure of the intervention. We urge further reflection on the fundamental assumptions that informed the design of that intervention and refer the reader to a more comprehensive treatment of that issue in the companion paper in this volume.
