Resuscitation preferences among patients with severe congestive heart failure: results from the SUPPORT project. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments.

BACKGROUND: We sought to describe the resuscitation preferences of patients hospitalized with an exacerbation of severe congestive heart failure, perceptions of those preferences by their physicians, and the stability of the preferences. METHODS AND RESULTS: Of 936 patients in this study, 215 (23%) explicitly stated that they did not want to be resuscitated. Significant correlates of not wanting to be resuscitated included older age, perception of a worse prognosis, poorer functional status, and higher income. The physician's perception of the patient's preference disagreed with the patient's actual preference in 24% of the cases overall. Only 25% of the patients reported discussing resuscitation preferences with their physician, but discussion of preferences was not significantly associated with higher agreement between the patient and physician. Of the 600 patients who responded to the resuscitation question again 2 months later, 19% had changed their preferences, including 14% of those who initially wanted resuscitation (69 of 480) and 40% of those who initially did not (48 of 120). The physician's perception of the patient's hospital resuscitation preference was correct for 84% of patients who had a stable preference and 68% of those who did not. CONCLUSIONS: Almost one quarter of patients hospitalized with severe heart failure expressed a preference not to be resuscitated. The physician's perception of the patient's preference was not accurate in about one quarter of the cases. but communication was not associated with greater agreement between the patient and the physician. A substantial proportion of patients who did not want to be resuscitated changed their minds within 2 months of discharge.

Death in the hospital.

OBJECTIVE: To examine symptoms and treatments among hospitalized adults in the last 2 days of life. METHODS: Review of 72 consecutive medical records of patients who died at an academic medical center and 32 consecutive medical records of patients who died at an affiliated Veterans Affairs hospital. Medical records were examined for documentation of symptoms, treatment, and orders to limit the use of life-sustaining interventions. RESULTS: The 104 patients who died had an average age of 68.9 years and 70 (68%) were men. The majority had neoplasms or acquired immunodeficiency syndrome, cardiovascular disease, and end-stage lung disease; the remainder died of other acute or chronic illnesses. In the last 2 days of life, pain was noted in 49 patients (46%). Dyspnea (n=53) and restlessness or agitation (n=50) were documented in 51% of the patients. In the last 48 hours of life 12 patients (12%) underwent an attempt at resuscitation, 26 patients (27%) were receiving ventilatory support, and 18% were restrained. Nearly half of the patients (48%) had an order or progress note specifying "comfort measures only" (CMO). Patients with CMO, compared with those without such orders, had similar levels of pain, agitation, and dyspnea. Patients with CMO were less likely to be in an intensive care unit (P=.001), receive ventilatory support (P=.001), receive antibiotics (P=.009), or be weighed (P=.001). CONCLUSIONS: Baseline information with which to begin improvement of care for dying individuals was obtained through a brief retrospective chart review. While patients with CMO receive less aggressive care, no specific process was used to provide comfort care. The evaluation and testing of processes of care for dying patients are necessary to begin the improvement of care. We provide baseline data about processes and outcomes of care in our hospitals.

Relationship between cancer patients' predictions of prognosis and their treatment preferences.

CONTEXT: Previous studies have documented that cancer patients tend to overestimate the probability of long-term survival. If patient preferences about the trade-offs between the risks and benefits associated with alternative treatment strategies are based on inaccurate perceptions of prognosis, then treatment choices may not reflect each patient's true values. OBJECTIVE: To test the hypothesis that among terminally ill cancer patients an accurate understanding of prognosis is associated with a preference for therapy that focuses on comfort over attempts at life extension. DESIGN: Prospective cohort study. SETTING: Five teaching hospitals in the United States. PATIENTS: A total of 917 adults hospitalized with stage III or IV non-small cell lung cancer or colon cancer metastatic to liver in phases 1 and 2 of the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). MAIN OUTCOME MEASURES: Proportion of patients favoring life-extending therapy over therapy focusing on relief of pain and discomfort, patient and physician estimates of the probability of 6-month survival, and actual 6-month survival. RESULTS: Patients who thought they were going to live for at least 6 months were more likely (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.8-3.7) to favor life-extending therapy over comfort care compared with patients who thought there was at least a 10% chance that they would not live 6 months. This OR was highest (8.5; 95% CI, 3.0-24.0) among patients who estimated their 6-month survival probability at greater than 90% but whose physicians estimated it at 10% or less. Patients overestimated their chances of surviving 6 months, while physicians estimated prognosis quite accurately. Patients who preferred life-extending therapy were more likely to undergo aggressive treatment, but controlling for known prognostic factors, their 6-month survival was no better. CONCLUSIONS: Patients with metastatic colon and lung cancer overestimate their survival probabilities and these estimates may influence their preferences about medical therapies.

Health values of hospitalized patients 80 years or older. HELP Investigators. Hospitalized Elderly Longitudinal Project.

CONTEXT: Health values (utilities or preferences for health states) are often incorporated into clinical decisions and health care policy when issues of quality vs length of life arise, but little is known about health values of the very old. OBJECTIVE: To assess health values of older hospitalized patients, compare their values with those of their surrogate decision makers, investigate possible determinants of health values, and determine whether health values change over time. DESIGN: A prospective, longitudinal, multicenter cohort study. SETTING: Four academic medical centers. PARTICIPANTS: Four hundred fourteen hospitalized patients aged 80 years or older and their surrogate decision makers who were interviewed and understood the task. MAIN OUTCOME MEASURES: Time-trade-off utilities, reflecting preferences for current health relative to a shorter but healthy life. RESULTS: On average, patients equated living 1 year in their current state of health with living 9.7 months in excellent health (mean [SD] utility, 0.81 [0.28]). Although only 126 patients (30.7%) rated their current quality of life as excellent or very good, 284 (68.6%) were willing to give up at most 1 month of 12 in exchange for excellent health (utility > or =0.92). At the other extreme, 25 (6.0%) were willing to live 2 weeks or less in excellent health rather than 1 year in their current state of health (utility < or =0.04). Patients were willing to trade significantly less time for a healthy life than their surrogates assumed they would (mean difference, 0.05; P=.007); 61 surrogates (20.3%) underestimated the patient's time-trade-off score by 0.25 (3 months of 12) or more. Patients willing to trade less time for better health were more likely to want resuscitation and other measures to extend life. Time-trade-off score correlated only modestly with quality-of-life rating (r=0.28) and inversely with depression score (r=-0.27), but there were few other clinical or demographic predictors of health values. When patients who survived were asked the time-trade-off question again at 1 year, they were willing to trade less time for better health than at baseline (mean difference, 0.04; P=.04). CONCLUSION: Very old hospitalized patients who could be interviewed were able, in most cases, to have their health values assessed using the time-trade-off technique. Most patients were unwilling to trade much time for excellent health, but preferences varied greatly. Because proxies and multivariable analyses cannot gauge health values of elderly hospitalized patients accurately, health values of the very old should be elicited directly from the patient.

Outcomes, preferences for resuscitation, and physician-patient communication among patients with metastatic colorectal cancer. SUPPORT Investigators. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments.

PURPOSE: To describe characteristics, outcomes, and decision making in patients with colorectal cancer metastatic to the liver, and to examine the relationship of doctor-patient communication with patient understanding of prognosis and physician understanding of patients' treatment preferences. PATIENTS AND METHODS: The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) was a prospective cohort study conducted at five teaching hospitals in the United States between 1989 and 1994. Participants in this study were hospitalized patients 18 years of age or older with known liver metastases who had been diagnosed with colorectal cancer at least 1 month earlier. Data were collected by patient interview and chart review at study entry; patients were interviewed again at 2 and 6 months. Data collected by physician interview included estimates of survival and impressions of patients' preferences for cardiopulmonary resuscitation (CPR). Patients and physicians were also asked about discussions about prognosis and resuscitation preferences. RESULTS: We studied 520 patients with metastatic colorectal cancer (median age 64, 56% male, 80% white, 2-month survival 78%, 6-month survival 56%). Quality of life (62% "good" to "excellent") and functional status (median number of disabilities = 0) were high at study entry and remained so among interviewed survivors at 2 and 6 months. Of 339 patients with available information, 212 (63%) of 339 wanted CPR in the event of a cardiopulmonary arrest. Factors independently associated with preference for resuscitation included younger age, better quality of life, absence of lung metastases, and greater patient estimate of 2-month prognosis. Of the patients who preferred not to receive CPR, less than half had a do-not-resuscitate note or order written. Patients' self-assessed prognoses were less accurate than those of their physicians. Physicians incorrectly identified patient CPR preferences in 30% of cases. Neither patient prognostication nor physician understanding of preferences were significantly better when discussions were reported between doctors and patients. CONCLUSIONS: A majority of patients with colorectal cancer have preferences regarding end of life care. The substantial misunderstanding between patients and their physicians about prognosis and treatment preferences appears not to be improved by direct communication. Future research focused on enhancing the effectiveness of communication between patients and physicians about end of life issues is needed.

Patient empowerment and feedback did not decrease pain in seriously ill hospitalized adults.

We tested a nurse clinician-mediated intervention to relieve pain in a group of seriously ill hospitalized adults using a randomized controlled trial at five tertiary care academic centers in the US. The study included 4804 patients admitted between January 1992 and January 1994 with one or more of nine high mortality diagnoses; 2652 were allocated to the intervention and 2152 to usual care. Specially-trained nurse clinicians assessed patients' pain, educated them and their families about pain control, empowered patients to expect pain relief, informed patients' nurses and physicians about level of pain and suggested or used other pain management resources. Patients' pain was determined from hospital interviews with patients and surrogates. Pain 2 and 6 months later or after death and satisfaction with its control at all time periods were also assessed. All analyses were adjusted for baseline risk of being in pain and propensity to be in the intervention group. Overall, 50.9% of patients reported some pain. After adjustment for other variables associated with pain, comparing the intervention to the control group, there was not a statistically significant difference in level of pain (OR for higher levels of pain 1.15; CI 1.00-1.32) or satisfaction with control of pain during the hospitalization (OR for higher levels of pain 1.12; CI 0.91-1.39), 2 or 6 months after discharge, or during the last 3 days of life. A multifaceted intervention using information, empowerment, advocacy, counseling and feedback was ineffective in ameliorating pain in seriously ill patients. Control of pain in these patients remains an important problem. More intensive pain treatment strategies addressing the needs of seriously ill hospitalized adults must be evaluated.

Role of written advance directives in decision making: insights from qualitative and quantitative data.

OBJECTIVE: To understand the role of written advance directives (ADs) in medical decision making through examination of qualitative and quantitative data sources. We specifically wanted to address whether physicians unilaterally disregard advance directives. DESIGN: Block randomized controlled trial to improve decision making and outcomes of seriously ill patients. SETTING: Five academic medical centers. PATIENTS: Fourteen hospitalized, seriously ill adults were randomized to receive an intervention of patient-specific information on prognoses and specially trained nurse to facilitate decision making. To be included in this analysis, patients reported having an AD and also met one of these criteria of severity: were comatose, had objective estimate of prognosis for surviving 2 months of 40% or less, or died during this hospital admission. MEASUREMENTS AND MAIN RESULTS: Quantitative data sources consisted of medical record review and interviews with the patient (when possible), surrogate, and responsible physician about prognosis, symptoms, preferences, and decision making. Qualitative data consisted of narratives by the nurse responsible for counseling and facilitating decision making. Each element of the quantitative database was reviewed, and a timeline of communication and decision making was constructed. Qualitative data were analyzed using grounded theory and narrative summary analysis. We compared and contrasted qualitative and quantitative data to better understand the role of ADs in decision making. In each case, the patient had a period of diminished capacity in which ADs should have been invoked. Advance directives played an important role in decision making of 5 of 14 cases, but even in those cases, life-sustaining treatment was stopped only when the patient was "absolutely, hopelessly ill." In two of these cases, the family member wrongly reported that the patient had an AD, and in the remaining seven cases, ADs had a limited role. The limited role could not be traced to a single explanation. Rather, a complex interaction of several factors was identified: patients were not considered hopelessly ill, so the directive was never seen as applicable and a transition in the goals of care did not occur; family members or the designated surrogate were not available, were ineffectual, or were overwhelmed; or the content of the AD was vague, or not applicable to the clinical situation, and the intent in completing the AD was never clarified. A physician did not unilaterally disregard a patient's preference in any of the cases. Two factors that enhanced the role of the AD were an available surrogate who was able to advocate for the patient and open communication between the physician and the surrogate in which the patient's prognosis was reconsidered. CONCLUSIONS: Our findings indicate that physicians are not unilaterally disregarding patients' ADs. Despite the patients' serious illnesses, family members and physicians did not see them as "absolutely, hopelessly ill." Hence, ADs were not considered applicable to the majority of these cases. Cases in which ADs had an impact evidenced open negotiation with a surrogate that yielded a transition in the goals of care.

Quality end of life care: the case for a MediCaring demonstration.

People in the last phase of life often need a very different care system than the one currently available. MediCaring extends the hospice model to a larger population with a wider array of services over a longer period of time with an emphasis on symptom management, maintenance of function, comfort and family counseling. This model requires simultaneous efforts to secure longer life and to make the patient and family ready for dying. Services range from psychological and spiritual counseling for the patient and family, to emergency care access, to inpatient respite care. MediCaring would accomplish these goals without increasing costs, primarily by diminishing the use of acute care interventions that may no longer serve the patient.

Physician experience caring for dying patients and its relationship to patient outcomes.

BACKGROUND: The quality of end-of-life care has become important to care systems and the public. No research has assessed how physician factors affect patient and family experience. OBJECTIVE: The objective of this study was to examine whether physicians' experience with dying is associated with differences in their patients' experiences while dying. METHODS: This was a prospective cohort study. Data were obtained from five geographically diverse teaching hospitals. The survey population was composed of 765 attending physicians who had at least one patient enrolled in a study of those with a high risk of dying. The patients were 8203 hospitalized adults who were at least 80 years of age or had one of nine serious illnesses. The physician survey provided information about physician characteristics. Physician experience with death was stratified into five groups according to self-reported rate of dying patients in the physician's practice. Patient outcomes included pain, anxiety, depression, satisfaction with pain relief, presence and timing of do-not-resuscitate orders, concordance with their physicians about cardiopulmonary resuscitation, and hospital resource use. RESULTS: Oncologists and pulmonologists or critical care physicians had more frequent contact with death. Physician characteristics other than specialty were not associated with death experience. Compared with the physician group having no experience with death, the adjusted odds ratios for accord on resuscitation preferences were 1.38 (95% confidence interval [CI], 0.96 to 1.98), 1.47 (95% CI, 1.03 to 2.11), 1.58 (95% CI, 1.10 to 2.26), and 1.64 (95% CI, 1.09 to 2.46) for the other four physician groups with progressively increasing experience. Other outcomes for patients were not associated with increasing physician experience. CONCLUSION: Most physicians have little experience with dying, and physicians' experience with death has little effect on patient outcomes. The concentration of experience in a small segment of physicians offers opportunities for targeting improvements in the care of dying patients, including physician education.

Capitated risk-bearing managed care systems could improve end-of-life care.

Capitated or salaried managed care systems offer an important opportunity to provide high quality, cost-effective end-of-life care. However, capitated healthcare delivery systems have strong incentives to avoid patient populations in need of such care. Care currently provided at the end of life in fee-for-service practice is commonly deficient, with high rates of avoidable pain and other burdens. Only hospice offers a better track record, yet access to hospice is limited, and length of stay is short. Traditional staff- or group-model managed care plans, with their emphasis on prevention, patient education, cost efficiency, service coordination, and integrated provider networks, present a dynamic set of conditions and organizational structures that would support real change. Advantages derived from managed care systems providing quality end-of-life care include coordinated care across delivery sites, interdisciplinary teams, integrated services, and opportunities to develop innovative care programs, service arrays, utilization controls, and accountability for care standards. We propose a special comprehensive system of managed care, which we call MediCaring, for seriously ill persons nearing the end of life. MediCaring would encompass the best elements of palliative care within a managed care structure: comprehensive, supportive, community-based services that meet personal and medical needs, a focus on patient preferences, symptom management, family counseling, and support. Other programs, such as hospice, have shown that continuity and coordinated care, financed through a capitated payment and directed at a special population, are both feasible and effective. There are obstacles to improving care at the end of life. Managed care systems, like most of medical care, have largely ignored the terminally ill patient. Current financing arrangements make it financially undesirable for insurers to recruit or retain the very sick; very ill patients can be costly over a prolonged time. In addition, inertia and habit inhibit change, and there are few criteria by which to judge whether care at the end-of-life is "good." Nevertheless, capitated or salaried managed care systems committed to enhanced end-of-life care seem well positioned to achieve it if payment reimbursements were revised to encourage this end.
