Factors associated with use of cardiopulmonary resuscitation in seriously ill hospitalized adults

Racial differences in predictors of intensive end-of-life care in patients with advanced cancer

PURPOSE

Black patients are more likely than white patients to receive life-prolonging care near death. This study examined predictors of intensive end-of-life (EOL) care for black and white advanced cancer patients.

PATIENTS AND METHODS

Three hundred two self-reported black (n = 68) and white (n = 234) patients with stage IV cancer and caregivers participated in a US multisite, prospective, interview-based cohort study from September 2002 to August 2008. Participants were observed until death, a median of 116 days from baseline. Patient-reported baseline predictors included EOL care preference, physician trust, EOL discussion, completion of a Do Not Resuscitate (DNR) order, and religious coping. Caregiver postmortem interviews provided information regarding EOL care received. Intensive EOL care was defined as resuscitation and/or ventilation followed by death in an intensive care unit.

RESULTS

Although black patients were three times more likely than white patients to receive intensive EOL care (adjusted odds ratio [aOR] = 3.04, P = .037), white patients with a preference for this care were approximately three times more likely to receive it (aOR = 13.20, P = .008) than black patients with the same preference (aOR = 4.46, P = .058). White patients who reported an EOL discussion or DNR order did not receive intensive EOL care; similar reports were not protective for black patients (aOR = 0.53, P = .460; and aOR = 0.65, P = .618, respectively).

CONCLUSION

White patients with advanced cancer are more likely than black patients with advanced cancer to receive the EOL care they initially prefer. EOL discussions and DNR orders are not associated with care for black patients, highlighting a need to improve communication between black patients and their clinicians.

Frailty and type of death among older adults in China: prospective cohort study

OBJECTIVE

To examine the association between frailty and type of death among the world's largest oldest-old population in China.

DESIGN

Prospective cohort study.

SETTING

2002 and 2005 waves of the Chinese longitudinal healthy longevity survey carried out in 22 provinces throughout China.

PARTICIPANTS

13 717 older adults (aged >or=65).

MAIN OUTCOME MEASURES

Type of death, categorised as being bedridden for fewer than 30 days with or without suffering and being bedridden for 30 or more days with or without suffering.

RESULTS

Multinomial analyses showed that higher levels of frailty significantly increased the relative risk ratios of mortality for all types of death. Of those with the highest levels of frailty, men were most likely to experience 30 or more bedridden days with suffering before death (relative risk ratio 8.70, 95% confidence interval 6.31 to 12.00) and women 30 or more bedridden days with no suffering (11.53, 17.84 to 16.96). Regardless of frailty, centenarians and nonagenarians were most likely to experience fewer than 30 bedridden days with no suffering, whereas those aged 65-79 and 80-89 were more likely to experience fewer than 30 bedridden days with suffering. Adjusting for compositional differences had little impact on the link between frailty and type of death for both sexes and age groups.

CONCLUSIONS

The association between frailty and type of death differs by sex and age. Health scholars and clinical practitioners should consider age and sex differences in frailty to develop more effective measures to reduce preventable suffering before death.

Religious coping and use of intensive life-prolonging care near death in patients with advanced cancer

CONTEXT

Patients frequently rely on religious faith to cope with cancer, but little is known about the associations between religious coping and the use of intensive life-prolonging care at the end of life.

OBJECTIVE

To determine the way religious coping relates to the use of intensive life-prolonging end-of-life care among patients with advanced cancer.

DESIGN, SETTING, AND PARTICIPANTS

A US multisite, prospective, longitudinal cohort of 345 patients with advanced cancer, who were enrolled between January 1, 2003, and August 31, 2007. The Brief RCOPE assessed positive religious coping. Baseline interviews assessed psychosocial and religious/spiritual measures, advance care planning, and end-of-life treatment preferences. Patients were followed up until death, a median of 122 days after baseline assessment.

MAIN OUTCOME MEASURES

Intensive life-prolonging care, defined as receipt of mechanical ventilation or resuscitation in the last week of life. Analyses were adjusted for demographic factors significantly associated with positive religious coping and any end-of-life outcome at P < .05 (ie, age and race/ethnicity). The main outcome was further adjusted for potential psychosocial confounders (eg, other coping styles, terminal illness acknowledgment, spiritual support, preference for heroics, and advance care planning).

RESULTS

A high level of positive religious coping at baseline was significantly associated with receipt of mechanical ventilation compared with patients with a low level (11.3% vs 3.6%; adjusted odds ratio [AOR], 2.81 [95% confidence interval {CI}, 1.03-7.69]; P = .04) and intensive life-prolonging care during the last week of life (13.6% vs 4.2%; AOR, 2.90 [95% CI, 1.14-7.35]; P = .03) after adjusting for age and race. In the model that further adjusted for other coping styles, terminal illness acknowledgment, support of spiritual needs, preference for heroics, and advance care planning (do-not-resuscitate order, living will, and health care proxy/durable power of attorney), positive religious coping remained a significant predictor of receiving intensive life-prolonging care near death (AOR, 2.90 [95% CI, 1.07-7.89]; P = .04).

CONCLUSIONS

Positive religious coping in patients with advanced cancer is associated with receipt of intensive life-prolonging medical care near death. Further research is needed to determine the mechanisms for this association.

Communication in end-stage cancer: review of the literature and future research

Concerns have been raised about the quality of life and health care received by cancer patients at the end of life (EOL). Many patients die with pain and other distressing symptoms inadequately controlled, receiving burdensome, aggressive care that worsens quality of life and limits patient exposure to palliative care, such as hospice. Patient-physician communication is likely a very important determinate of EOL care. Discussions of EOL with physicians are associated with an increased likelihood of the following (1) acknowledgment of terminal illness, (2) preferences for comfort care over life extension, and (3) receipt of less intensive, life-prolonging and more palliative EOL care; while this appears to hold for White patients, it is less clear for Black, advanced cancer patients. These results highlight the importance of communication in determining EOL cancer care and suggest that communication disparities may contribute to Black-White differences in EOL care. We review the pertinent literature and discuss areas for future research.

Advance care planning and health care preferences of community-dwelling elders: the Framingham Heart Study

OBJECTIVE

The study objective was to describe self-reported advance care planning, health care preferences, use of advance directives, and health perceptions in a very elderly community-dwelling sample.

METHODS

We interviewed surviving participants of the original cohort of the Framingham Heart Study who were cognitively intact and attended a routine research examination between February 2004 and October 2005. Participants were queried about discussions about end-of-life care, preferences for care, documentation of advance directives, and health perceptions.

RESULTS

Among 220 community-dwelling respondents, 67% were women with a mean age of 88 years (range 84-100 years). Overall, 69% discussed their wishes for medical care at the end of life with someone, but only 17% discussed their wishes with a physician or health care provider. Two thirds had a health care proxy, 55% had a living will, and 41% had both. Most (80%) respondents preferred comfort care over life-extending care, and 71% preferred to die at home; however, substantially fewer respondents said they would rather die than receive specific life-prolonging interventions (chronic ventilator [63%] or feeding tube [64%]). Many were willing to endure distressing health states, with fewer than half indicating that they would rather die than live out their life in a great deal of pain (46%) or be confused and/or forgetful (45%) all of the time.

CONCLUSIONS

Although the vast majority of very elderly community-dwellers in this sample appear to prefer comfort measures at the end of life, many said they were willing to endure specific life-prolonging interventions and distressing health states to avoid death. Our results highlight the need for physicians to better understand patients' preferences and goals of care to help them make informed decisions at the end of life.

Racial and ethnic differences in the treatment of seriously ill patients: a comparison of African-American, Caucasian and Hispanic veterans

BACKGROUND

No national data exist regarding racial/ethnic differences in the use of interventions for patients at the end of life.

OBJECTIVES

To test whether among 3 cohorts of hospitalized seriously ill veterans with cancer, noncancer or dementia the use of common life-sustaining treatments differed significantly by race/ethnicity.

DESIGN

Retrospective cohort study during fiscal years 1991-2002.

PATIENTS

Hospitalized veterans >55 years, defined clinically as at high-risk for 6-month mortality, not by decedent data.

MEASUREMENTS

Utilization patterns by race/ethnicity for 5 life-sustaining therapies. Logistic regression models evaluated differences among Caucasians, African Americans and Hispanics, controlling for age, disease severity and clustering of patients within Veterans Affairs (VA) medical centers.

RESULTS

Among 166,059 veterans, both differences and commonalities across diagnostic cohorts were found. African Americans received more or the same amount of end-of-life treatments across disease cohorts, except for less resuscitation [OR = 0.84 (0.77-0.92), p = 0.002] and mechanical ventilation [OR = 0.89 (0.85-0.94), p < or = 0.0001] in noncancer patients. Hispanics were 36% (cancer) to 55% (noncancer) to 88% (dementia) more likely to receive transfusions than Caucasians (p < 0.0001). They received similar rates as Caucasians for all other interventions in all other groups, except for 161% higher likelihood for mechanical ventilation in patients with dementia. Increased end-of-life treatments for both minority groups were most pronounced in the dementia cohort. Differences demonstrated a strong interaction with the disease cohort.

CONCLUSIONS

Differences in level of end-of-life treatments were disease specific and bidirectional for African Americans. In the absence of generally accepted, evidence-based standards for end-of-life care, these differences may or may not constitute disparities.

Health literacy not race predicts end-of-life care preferences

BACKGROUND

Several studies have reported that African Americans are more likely than whites to prefer aggressive treatments at the end of life.

OBJECTIVE

Since the medical information presented to subjects is frequently complex, we hypothesized that apparent differences in end-of-life preferences and decision making may be due to disparities in health literacy. A video of a patient with advanced dementia may overcome communication barriers associated with low health literacy.

DESIGN

Before and after oral survey.

PARTICIPANTS

Subjects presenting to their primary care doctors.

METHODS

Subjects were asked their preferences for end-of-life care after they heard a verbal description of advanced dementia. Subjects then viewed a 2-minute video of a patient with advanced dementia and were asked again about their preferences. For the analysis, preferences were dichotomized into comfort care and aggressive care. Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine (REALM) and subjects were divided into three literacy categories: low (0-45, sixth grade and below), marginal (46-60, seventh to eighth grade) and adequate (61-66, ninth grade and above). Unadjusted and adjusted logistic regression models were fit using stepwise algorithms to examine factors related to initial preferences before the video.

RESULTS

A total of 80 African Americans and 64 whites completed the interview. In unadjusted analyses, African Americans were more likely than whites to have preferences for aggressive care after the verbal description, odds ratio (OR) 4.8 (95% confidence interval [CI] 2.1-10.9). Subjects with low or marginal health literacy were also more likely than subjects with adequate health literacy to have preferences for aggressive care after the verbal description, OR 17.3 (95% CI 6.0-49.9) and OR 11.3 (95% CI 4.2-30.8) respectively. In adjusted analyses, health literacy (low health literacy: OR 7.1, 95% CI 2.1-24.2; marginal health literacy OR 5.1, 95% CI 1.6-16.3) but not race (OR 1.1, 95% CI 0.3-3.2) was an independent predictor of preferences after the verbal description. After watching a video of advanced dementia, there were no significant differences in the distribution of preferences by race or health literacy.

CONCLUSIONS

Health literacy and not race was an independent predictor of end-of-life preferences after hearing a verbal description of advanced dementia. In addition, after viewing a video of a patient with advanced dementia there were no longer any differences in the distribution of preferences according to race and health literacy. These findings suggest that clinical practice and research relating to end-of-life preferences may need to focus on a patient education model incorporating the use of decision aids such as video to ensure informed decision-making.

What accounts for differences or disparities in pediatric palliative and end-of-life care? A systematic review focusing on possible multilevel mechanisms

OBJECTIVE

The goal was to clarify potential mechanisms underlying differences/disparities in pediatric palliative and end-of-life care.

METHODS

We systematically searched online databases to identify articles relating to differences/disparities in pediatric palliative and end-of-life care, retaining 19 studies for evaluation. We then augmented this search with a broader review of the literature on the mechanisms of differences/disparities in adult palliative and end-of-life care, general pediatrics, adult medicine, and pain.

RESULTS

The concept of reciprocal interaction can organize and illuminate interacting mechanisms across 3 levels of human organization, namely, broader contextual influences on patients and clinicians, specific patient-provider engagements, and specific patients. By using this rubric, we identified 10 distinct mechanisms proposed in the literature. Broader contextual influences include health care system structures; access to care; and poverty, socioeconomic status, social class, and family structure. Patient-clinician engagements encompass clinician bias, prejudice, and stereotypes; concordance of race; quality of information exchange; and trust. Patient-specific features include perceptions of control; religion and spirituality; and medical conditions.

CONCLUSIONS

Differences and disparities in pediatric palliative and end-of-life care can be understood as arising from various mechanisms that interact across different levels of human organization, and this interactive multilevel model should be considered in designing studies or planning interventions to understand differences and to ameliorate disparities.

Using the medical record to evaluate the quality of end-of-life care in the intensive care unit

RATIONALE

We investigated whether proposed "quality markers" within the medical record are associated with family assessment of the quality of dying and death in the intensive care unit (ICU).

OBJECTIVE

To identify chart-based markers that could be used as measures for improving the quality of end-of-life care.

DESIGN

A multicenter study conducting standardized chart abstraction and surveying families of patients who died in the ICU or within 24 hrs of being transferred from an ICU.

SETTING

ICUs at ten hospitals in the northwest United States.

PATIENTS

Overall, 356 patients who died in the ICU or within 24 hrs of transfer from an ICU.

MEASUREMENTS

The 22-item family assessed Quality of Dying and Death (QODD-22) questionnaire and a single item rating of the overall quality of dying and death (QODD-1).

ANALYSIS

The associations of chart-based quality markers with QODD scores were tested using Mann-Whitney U tests, Kruskal-Wallis tests, or Spearman's rank-correlation coefficients as appropriate.

RESULTS

Higher QODD-22 scores were associated with documentation of a living will (p = .03), absence of cardiopulmonary resuscitation performed in the last hour of life (p = .01), withdrawal of tube feeding (p = .04), family presence at time of death (p = .02), and discussion of the patient's wish to withdraw life support during a family conference (p < .001). Additional correlates with a higher QODD-1 score included use of standardized comfort care orders and occurrence of a family conference (p < or = .05).

CONCLUSIONS

We identified chart-based variables associated with higher QODD scores. These QODD scores could serve as targets for measuring and improving the quality of end-of-life care in the ICU.

Nurses' involvement in 'do not resuscitate' decisions on acute elder care wards

AIM

This paper reports the involvement of nurses in 'do not resuscitate' decision-making on acute elder care wards and their adherence to such decisions in the case of an actual cardiopulmonary arrest.

BACKGROUND

Previous literature showed that nurses are involved in half or less than half of 'do not resuscitate' decisions in hospitals, but their involvement in this decision-making on acute elder care wards in particular has not been investigated.

METHOD

A questionnaire was sent in 2002 to the head nurses of all acute elder care wards in Flanders, Belgium (n = 94). They were asked whether nurses had been involved in the last 'do not resuscitate' decision-making process on their ward and whether nurses 'never', 'rarely', 'sometimes', 'often' or 'always' started resuscitation in case of cardiopulmonary arrest of patients with 'do not resuscitate' status and of those without.

RESULTS

The response rate was 86.2% (n = 81). In 74.7% of the last 'do not resuscitate' decisions on acute elder care wards in Flanders, a nurse was involved in the decision-making process. For patients with 'do not resuscitate' status, 54.3% of respondents reported that cardiopulmonary resuscitation was 'never' started on their ward, 'rarely' on 39.5% and 'sometimes' on 6.2%. For patients without 'do not resuscitate' status, nurses started cardiopulmonary resuscitation 'rarely' or 'sometimes' on 22.2% of all wards, and 'often' or 'always' on 77.8%.

CONCLUSION

To make appropriate 'do not resuscitate' decisions and to avoid rash decision-making in cases of actual cardiopulmonary arrest, nurses should be involved early in 'do not resuscitate' decision-making. If institutional 'do not resuscitate' guidelines were to stress more clearly the important role of nurses in all kinds of end-of-life decisions, this might improve the 'do not resuscitate' decision-making process.

Functional assessment of older patients in the emergency department: comparison between standard instruments, medical records and physicians' perceptions

Background

We evaluated the accuracy of physician recognition of functional status impairment in older emergency departments (ED) patients. In particular, we evaluated the accuracy of medical records (a comparison of the information in the medical record with the functional status based on proxy interviews), and the accuracy of physician knowledge (a comparison of the information obtained from the responsible physician with the functional status based on proxy interviews).

Methods

Cross-sectional study on 101 frail older patients selected at random from among those attending ED, their ED physicians, and respondents. The study was conducted at ED in four general university teaching hospitals in a city, from July through November 2003. Functional data shown on patients' medical records were compared against functional data obtained from respondents (family members), using Kendall's Tau-b statistic. In addition patients' Katz Indices (which assesses six basic activities of daily living – basic ADL) based on interviews with ED physicians were compared against those obtained from respondents, using the coefficient of concordance weighted kappa (κ). Each patient and his respondent were paired with a single physician.

Results

The correlation between information on dependence for basic ADL obtained from medical records and that furnished by respondents, was 0.41 (95% CI 0.27–0.55). Concordance between the respective Katz Indices obtained from physicians and respondents was 0.47 (95% CI 0.38–0.57).

Conclusion

Older subjects' functional status is not properly assessed by emergency department physicians.

Deferred decision making: patients' reliance on family and physicians for CPR decisions in critical care

The aim of this study was to investigate factors associated with seriously ill patients' preferences for their family and physicians making resuscitation decisions on their behalf. Using SUPPORT II data, the study revealed that, among 362 seriously ill patients who were experiencing pain, 277 (77%) answered that they would want their family and physicians to make resuscitation decisions for them instead of their own wishes being followed if they were to lose decision-making capacity. Even after controlling for other variables, patients who preferred the option of undergoing cardiopulmonary resuscitation (CPR) in the future were twice as likely, and those who had had ventilator treatment were four-fifths less likely, to rely on their family and physicians than those who did not want CPR (odds ratio (OR) = 2.28; 95% confidence interval (CI) 1.18-4.38) or those who had not received ventilator treatment (OR = 0.23; 95% CI 0.06-0.90). Psychological variables (anxiety, quality of life, and depression), symptomatic variables (severity of pain and activities of daily living) and the existence of surrogates were not significantly associated with patients' preferences for having their family and physicians make resuscitation decisions for them. Age was not a significant factor for predicting the decision-making role after controlling for other variables.

Focus group findings about the influence of culture on communication preferences in end-of-life care

BACKGROUND

Little guidance is available for health care providers who try to communicate with patients and their families in a culturally sensitive way about end-of-life care.

OBJECTIVE

To explore the content and structure of end-of-life discussions that would optimize decision making by conducting focus groups with two diverse groups of patients that vary in ethnicity and socioeconomic status.

DESIGN

Six focus groups were conducted; 3 included non-Hispanic white patients recruited from a University hospital (non-Hispanic white groups) and 3 included African-American patients recruited from a municipal hospital (African-American groups). A hypothetical scenario of a dying relative was used to explore preferences for the content and structure of communication.

PARTICIPANTS

Thirty-six non-Hispanic white participants and 34 African-American participants.

APPROACH

Content analysis of focus group transcripts.

RESULTS

Non-Hispanic white participants were more exclusive when recommending family participants in end-of-life discussions while African-American participants preferred to include more family, friends and spiritual leaders. Requested content varied as non-Hispanic white participants desired more information about medical options and cost implications while African-American participants requested spiritually focused information. Underlying values also differed as non-Hispanic white participants expressed more concern with quality of life while African-American participants tended to value the protection of life at all costs.

CONCLUSIONS

The groups differed broadly in their preferences for both the content and structure of end-of-life discussions and on the values that influence those preferences. Further research is necessary to help practitioners engage in culturally sensitive end-of-life discussions with patients and their families by considering varying preferences for the goals of end-of-life care communication.

The influence of spiritual beliefs and practices on the treatment preferences of African Americans: a review of the literature

Spirituality is an important part of African-American culture and is often cited as an explanation for the more-aggressive treatment preferences of some African Americans at the end of life. This paper reviews the literature on spiritual beliefs that may influence the treatment decisions of African Americans. Medline 1966 to February 2003, Psych Info 1872 to February 2003, and CINAHL 1982 to February 2003 were searched for studies exploring spiritual beliefs that may influence the treatment preferences of African Americans. All candidate papers were examined for quality, and data were extracted on study population, design, analysis, and results to identify recurrent themes. Forty studies met inclusion criteria. Recurrent themes describing spiritual beliefs that may influence the treatment preferences of African Americans throughout the course of illness include the following: spiritual beliefs and practices are a source of comfort, coping, and support and are the most effective way to influence healing; God is responsible for physical and spiritual health; and the doctor is God's instrument. Spiritual beliefs specifically addressing treatment preferences at the end of life include: only God has power to decide life and death, there are religious prohibitions against physician-assisted death or advance directives limiting life-sustaining treatments, and divine intervention and miracles occur. For some African Americans, spiritual beliefs are important in understanding and coping with illness and may provide a framework within which treatment decisions are made. Given the growing ethnic diversity of the United States, some understanding of the complexities of culture and spirituality is essential for healthcare providers.

Quality of Dying and Death in Two Medical ICUs

OBJECTIVE

We compared perceptions of the quality of dying and death in the ICU across nurses, resident physicians, attending physicians, and family members. The aim was to obtain a surrogate assessment of the quality of the dying process and examine differences in the perceptions of different types of raters.

DESIGN

Cross-sectional survey of family members and ICU clinicians conducted following the death of enrolled patients.

SETTING

Two medical ICUs at academic tertiary care medical centers.

PATIENTS

Patients dying in the ICU (n = 68).

MEASUREMENTS AND RESULTS

The previously validated Quality of Dying and Death (QODD) instrument was modified for use in the ICU. Within 48 h of the time of death, the nurse, resident, and attending physician caring for the patient were asked to complete the QODD. One month following the death, a designated family member was contacted and the QODD was administered on the telephone. Family members and attending physicians gave the most favorable ratings of death, while nurses and residents provided less favorable ratings. Significant differences between these groups were notable (p < 0.01) on items related to patient autonomy: maintaining dignity, being touched by loved ones, and the overall quality of death.

CONCLUSIONS

The perception of dying and death in the ICU varies considerably between nurses, attending physicians, resident physicians, and family members. Further studies are needed to explain these differences and determine the utility of the ICU QODD instrument for assessing and improving the quality of end-of-life care in the ICU.

Predictors of do not resuscitate orders in the nursing home

BACKGROUND

The outcome of cardiopulmonary resuscitation of residents of long-term care facilities is poor. However, only about one half of residents of long term care facilities have a do not resuscitate (DNR) order. The remainder usually have resuscitation by order or by default policy. Understanding predictors of DNR may help clinicians address end-of-life issues with the older long-term care population.

OBJECTIVES

To determine (1) the prevalence of DNR orders, and (2) predictors of DNR orders in older institutionalized individuals in a large community teaching nursing home.

METHODS

A cross-sectional chart review study of 177 consecutively located older patients from an 899-bed academic long-term care facility.

RESULTS

The prevalence of a DNR order was 40%. The frequency of ordering DNR was greater in subjects who were 85 years or older compared with subjects who were younger than 85 years (57% vs. 30%, P < .05). Ordering DNR was associated significantly with race (49% of whites compared with 13% African Americans, P < .05) but not with sex. Subjects with a DNR order were more likely to have been diagnosed with depression (52% vs. 35%, P < .05) but not dementia, and overall had greater number of medical conditions (5.9 +/- 2 vs. 5.1 +/- 2, P < .05) compared with subjects without DNR orders. The frequency of DNR orders did not significantly differ between subjects who were able to ambulate (with or without assistance) compared with subjects who were wheelchair or bed bound. Using logistic regression analysis, only age (with a B of -1.04 and P of .017) and race (with a B of 1.4 and a P of .01) were independent predictors of DNR status.

CONCLUSION

Fewer than half of this sample of long-term care residents had a DNR order. Among seven factors studied, only age and race were independent predictors of DNR status in the nursing home.

The impact of a neurointensivist-led team on a semiclosed neurosciences intensive care unit*

OBJECTIVE

To evaluate the impact of a newly appointed neurointensivist on neurosciences intensive care unit (NICU) patient outcomes and quality of care variables.

DESIGN

Observational cohort with historical controls.

SETTING

Ten-bed neurointensive care unit in tertiary university hospital.

PATIENTS

Mortality, length of stay (LOS), and discharge disposition of all patients admitted to the NICU were compared between two 19-month periods, before and after the appointment of a neurointensivist. Data regarding these patients were collected using the hospital database and the University Hospitals Consortium database. Individual patient medical records were reviewed for major complications and important prognostic variable documentation.

INTERVENTIONS

Appointment of a neurointensivist.

MEASUREMENTS AND MAIN RESULTS

We analyzed 1,087 patients before and 1,279 after the neurointensivist's appointment. The unadjusted in-hospital mortality decreased from 10.1% in the before to 9.1% in the after period (95% confidence interval, -1.3 to 3%, relative mortality reduction of 9.9%), but this decrease was significantly different than the expected increase of 1.4% in University Hospitals Consortium mortality during the same period (p = .048). The unadjusted mortality in the NICU decreased from 8% to 6.3% (95% confidence interval, -0.5 to 4, relative mortality reduction 21%) and mean NICU LOS from 3.5 to 2.9 days (95% confidence interval, 0.2 to 0.9, relative NICU LOS reduction 17%). A significant 42% reduction of the risk of death during the first 3 days of NICU admission (p = .003) and a 12% greater risk for NICU discharge (p = .02) were found in the after period in multivariate proportional hazard models. Discharge home increased from 51.7% in the before to 59.7% in the after period (95% confidence interval, 4 to 12, relative increase of 15%) and discharge to a nursing home decreased from 8.1% to 6.8% (95% confidence interval, -1 to 4, relative decrease of 16%). Although a higher total number of complications occurred in the after period, fewer of them occurred in the NICU (odds ratio, 0.2; 95% confidence interval, 0.08 to 0.54, p = .001); this may possibly be due to the better documentation by the NICU team in the after period.

CONCLUSIONS

The institution of a neurointensivist-led team model was associated with an independent positive impact on patient outcomes, including a lower intensive care unit mortality, LOS, and discharge to a skilled nursing facility and a higher discharge home.

Knowledge, attitudes, and beliefs about end-of-life care among inner-city African Americans and Latinos

OBJECTIVE

This project explored end-of-life care preferences and barriers among low-income, urban African Americans and Latino/Hispanic Americans (Latinos) to uncover factors that may influence hospice utilization.

METHODS

Focus groups were conducted separately for African Americans (4 groups, n = 26) and Latinos (4 groups, n = 27). Transcripts were coded and analyzed using consensus and triangulation to identify primary themes.

RESULTS

Four preference themes and four barriers were identified. Results were largely similar across the two groups. Both preferred having families provide care for loved ones but expressed desire to reduce caretaker burden. Groups emphasized spirituality as the primary means of coping and valued the holistic well-being of the patient and family. Barriers reported were closely tied to access to care. Participants reported low hospice utilization because of lack of awareness of hospice and the prohibitive cost of health care. Latinos were more likely to report language barriers, while African Americans were more likely to report mistrust of the system.

CONCLUSIONS

African Americans and Latinos in this study were highly receptive to end-of-life care that would provide relief for patients and caregivers and emphasize spirituality and family consensus. Improving awareness of hospice services would likely increase utilization.

Ethical issues in geriatrics: a guide for clinicians

Because of demographic trends, it is reasonable to expect that clinicians will care for an increasing number of elderly persons with challenging medical and psychosocial problems. These problems and issues, in turn, may lead to daunting ethical dilemmas. Therefore, clinicians should be familiar with ethical dilemmas commonly encountered when caring for elderly patients. We review some of these dilemmas, including ensuring informed consent and confidentiality, determining decision-making capacity, promoting advance care planning and the use of advance directives, surrogate decision making, withdrawing and withholding interventions, using cardiopulmonary resuscitation and do-not-resuscitate orders, responding to requests for interventions, allocating health care resources, and recommending nursing home care. Ethical dilemmas may arise because of poor patient-clinician communication; therefore, we provide practical tips for effective communication. Nevertheless, even in the best circumstances, ethical dilemmas occur. We describe a case-based approach to ethical dilemmas used by the Mayo Clinic Ethics Consultation Service, which begins with a review of the medical indications, patient preferences, quality of life, and contextual features of a given case. This approach enables clinicians to identify and analyze the relevant facts of a case, define the ethical problem, and suggest a solution.

Hospitalization of Hospice Patients with Cancer

OBJECTIVES

To identify factors associated with hospitalization of elderly hospice patients with cancer and to describe their hospital experiences.

DESIGN

Retrospective analysis of the last year of life.

SETTING

Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database.

PARTICIPANTS

Medicare beneficiaries dying of lung or colorectal cancer between 1988 and 1998 who enrolled in hospice.

MEASUREMENTS

Hospitalization after hospice entry. For hospitalized patients, we describe admission diagnoses, aggressiveness of care, and in-hospital death.

RESULTS

Of the 23608 patients, 1423 (6.0%) were hospitalized after hospice enrollment. Hospitalization declined over time by 7.0% per year of hospice enrollment. Factors associated with higher hospitalization rates were younger age, male gender, black race/ethnicity, local cancer stage at diagnosis, and hospice enrollment within 4 months of cancer diagnosis. The most common reasons for hospital admission were lung cancer, metastatic disease, bone fracture, pneumonia, and volume depletion. Of the 1423 patients hospitalized, 34.6% received aggressive care and 35.8% died in the hospital.

CONCLUSION

The rates of hospitalization for elderly hospice patients with lung or colorectal cancer appear to be declining. However, patients who are hospitalized undergo aggressive care and often die in the hospital rather than at home. This aggressive care may be consistent with changes in patients' care preferences, but could also reflect the current culture of acute care hospitals, which focuses on curative treatment and is ill-equipped to provide palliative care.

Hospice usage by minorities in the last year of life: results from the National Mortality Followback Survey

OBJECTIVES

To examine racial/ethnic variations in rates of hospice use in a national cohort and to identify individual characteristics associated with hospice use.

DESIGN

Secondary analysis of the 1993 National Mortality Followback Survey (NMFS), a nationally obtained sample using death certificates and interviews with relatives (proxy respondents) to provide mortality, social, and economic data and information about healthcare utilization in the last year of life for 23,000 deceased individuals.

SETTING

Hospice care.

PARTICIPANTS

Individuals aged 15 and older who died in 1993. Subjects were included in this analysis if they died of nontraumatic causes (N = 11,291).

MEASUREMENTS

Hospice use was dichotomized by proxy responses indicating use or nonuse of home or inpatient hospice services. The percentage of individuals using hospice services in the last year of life was calculated.

RESULTS

Unadjusted bivariate results found that African Americans were less likely to use hospice than whites (odds ratio (OR) = 0.59; P <.001) and that those without a living will (LW) (OR = 0.23; P <.001) and without a cancer diagnosis (OR = 0.28; P <.001) were less likely to use hospice. The negative relationship between African Americans and hospice use was unaffected when controlled for sex, education, marital status, existence of a LW, income, and access to health care. Logistic models revealed that presence of a LW diminished the negative relationship between African Americans and hospice use, but the latter remained significant (OR = 0.83; P =.033). A subanalysis of subjects aged 55 and older showed a significant interaction between access to care and race/ethnicity with respect to hospice use (P =.044). Inclusion of income in this multivariable logistic model attenuated the relationship between African-American race/ethnicity and hospice use (OR = 0.77), and the difference between whites and African Americans became only marginally statistically significant (P =.060).

CONCLUSION

In the 1993 NMFS, hospice use was negatively associated with African-American race/ethnicity independent of income and access to healthcare. The relationship is not independent of age, insurance type, or history of stroke. For subjects aged 55 and older, access to healthcare may be an important confounder of the negative relationship between African-American race/ethnicity and hospice use. Consistent with previous studies, this analysis found that African Americans were less likely to use LWs than whites. The reduced importance of African-American race/ethnicity on hospice use with the inclusion of presence of a LW in logistic models suggests that similar cultural processes may shape differences between African Americans and whites in advance care planning and hospice use.

Do-not-resuscitate order after 25 years

BACKGROUND

In 1976, the first hospital policies on orders not to resuscitate were published in the medical literature. Since that time, the concept has continued to evolve and evoke much debate. Indeed, few initials in medicine today evoke as much symbolism or controversy as the Do-Not-Resuscitate (DNR) order.

OBJECTIVE

To review the development, implementation, and present standing of the DNR order.

DESIGN

Review article.

MAIN RESULTS

The DNR order concept brought an open decision-making framework to the resuscitation decision and did much to put appropriate restraint on the universal application of cardiopulmonary resuscitation for the dying patient. Yet, even today, many of the early concerns remain.

CONCLUSIONS

After 25 yrs of DNR orders, it remains reasonable to presume consent and attempt resuscitation for people who suffer an unexpected cardiopulmonary arrest or for whom resuscitation may have physiologic effect and for whom no information is available at the time as to their wishes (or those of their surrogate). However, it is not reasonable to continue to rely on such a presumption without promptly and actively seeking to clarify the patient's (or surrogate's) wishes. The DNR order, then, remains an inducement to seek the informed patient's directive.

Barriers to hospice care among older patients dying with lung and colorectal cancer

PURPOSE

To identify factors associated with hospice enrollment and length of stay in hospice among patients dying with lung or colorectal cancer.

METHODS

We used the Linked Medicare-Tumor Registry Database to conduct a retrospective analysis of the last year of life among Medicare beneficiaries diagnosed with lung or colorectal cancer at age > or = 66 years between January 1, 1973, and December 31, 1996, in the Surveillance, Epidemiology, and End Results Program who died between January 1, 1988, and December 31, 1998. Our outcomes of interest were time from cancer diagnosis to hospice enrollment and length of stay in hospice care. We used Cox proportional hazards regression to adjust for demographic and clinical information.

RESULTS

We studied elderly patients dying with lung cancer (n = 62,117) or colorectal cancer (n = 57,260). Overall, 27% of patients (n = 16,750) with lung cancer and 20% of patients (n = 11,332) with colorectal cancer received hospice care before death. Median length of stay for hospice patients with lung and colorectal cancer was 25 and 28 days, respectively. Overall, 20% of patients entered hospice within 1 week of death, whereas 6% entered more than 6 months before death. Factors associated with later hospice enrollment include being male; being of nonwhite, nonblack race; having fee-for-service insurance; and residing in a rural community. Many of these factors also were associated with shorter stays in hospice.

CONCLUSION

Although use of hospice care has increased dramatically over time, specific patient groups, including men, patients residing in rural communities, and patients with fee-for-service insurance continue to experience delays in hospice enrollment.

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.

"Choice" in end-of-life decision making: researching fact or fiction?

PURPOSE

The contribution of bioethics to clinical care at the end of life (EOL) deserves critical scrutiny. We argue that researchers have rarely questioned the normative power of autonomy-based bioethics practices. Research on the ethical dimensions of EOL decision making has focused on an idealized discourse of patient "choice" that requires patients to embrace their dying to receive excellent palliative care.

DESIGN AND METHODS

Our critique is based on a comprehensive review of empirical research exploring bioethics practices at the EOL. In addition we will provide a brief review of our own ethnographic, longitudinal study of the decision-making experience of dying patients, their families, and their health care providers.

RESULTS

There is little or no empirical evidence to support the autonomy paradigm of patient "choice" in EOL decision making. What we found is that (a). prognostication at the EOL is problematic and resisted; (b). shared decision making is illusory, patients often resist advance care planning and hold other values more important than autonomy, and system characteristics are more determinative of EOL care than patient preferences; and (c). the incommensurability of medical and lay knowledge and values and the multifaceted and processual nature of patient and family decision making are at odds with the current EOL approach toward advance care planning.

IMPLICATIONS

It is exceedingly difficult to identify, study, and critique normative assumptions without creating them, reproducing them, or obliterating them in the process. However, a fuller account of the morally significant domains of end-of-life care is needed. Researchers and policy makers should heed what we have learned from empirical research on EOL care to develop more sensitive and supportive programs for care of the dying.

Barriers to optimum end-of-life care for minority patients

Although major efforts are underway to improve end-of-life care, there is growing evidence that improvements are not being experienced by those at particularly high risk for inadequate care: minority patients. Ethnic disparities in access to end-of-life care have been found that reflect disparities in access to many other kinds of care. Additional barriers to optimum end-of-life care for minority patients include insensitivity to cultural differences in attitudes toward death and end-of-life care and understandable mistrust of the healthcare system due to the history of racism in medicine. These barriers can be categorized as institutional, cultural, and individual. Efforts to better understand and remove each type of barrier are needed. Such efforts should include quality assurance programs to better assess inequalities in access to end-of-life care, political action to address inadequate health insurance and access to medical school for minorities, and undergraduate and continuing medical education in cultural sensitivity.

Cardiopulmonary resuscitation directives on admission to intensive-care unit: an international observational study

BACKGROUND

Resuscitation directives should be a sign of patient's preference. Our objective was to ascertain prevalence, predictors, and procurement pattern of cardiopulmonary resuscitation directives within 24 h of admission to the intensive-care unit (ICU).

METHODS

We enrolled 2916 patients aged 18 years and older from 15 ICUs in four countries, and recorded whether, when, and by whom their cardiopulmonary resuscitation directives were established. By polychotomous logistic regression we identified factors associated with a resuscitate or do-not-resuscitate directive.

FINDINGS

Of 2916 patients, 318 (11%; 95% CI 9.8-12.1) had an explicit resuscitation directive. In 159 (50%; 44.4-55.6) patients, the directive was do-not-resuscitate. Directives were established by residents for 145 (46%; 40.0-51.3) patients. Age strongly predicted do-not-resuscitate directives: for 50-64, 65-74, and 75 years and older, odds ratios were 3.4 (95% CI 1.6-7.3), 4.4 (2.2-9.2), and 8.8 (4.4-17.8), respectively. APACHE II scores greater than 20 predicted resuscitate and do-not-resuscitate directives in a similar way. An explicit directive was likely for patients admitted at night (odds ratio 1.4 [1.0-1.9] and 1.6 [1.2-2.3] for resuscitate and do-not-resuscitate, respectively) and during weekends (1.9 [1.3-2.7] and 2.2 [1.5-3.2], respectively). Inability to make a decision raised the likelihood of a do-not-resuscitate (3.7 [2.6-5.4]) than a resuscitate (1.7 [1.2-2.3]) directive (p=0.0005). Within Canada and the USA, cities differed strikingly, as did centres within cities.

INTERPRETATION

Cardiopulmonary resuscitation directives established within 24 h of admission to ICU are uncommon. As well as clinical factors, timing and location of admission might determine rate and nature of resuscitation directives.

Ethical and legal issues in palliative care

As palliative care emerges as a respected and important component of contemporary health care, ethical issues will arise that confront and contest the provision of medical care. The basic principles of medical ethics, embodied in beneficence, nonmaleficence, autonomy, and justice, guide primary care physicians in dealing with dying patients. This article will discuss the basic ethical principles and the principle of double effect, decision-making capacity, advance directives, withholding and withdrawing life-sustaining therapy, futility, artificial nutrition and hydration, do-not-resuscitate orders, and physician-assisted suicide and euthanasia.

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

BACKGROUND

The intervention in SUPPORT, the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments, was ineffective in changing communication, decision-making, and treatment patterns despite evidence that counseling and information were delivered as planned. The previous paper in this volume shows that modest alterations in the intervention design probably did not explain the lack of substantial effects.

OBJECTIVE

To explore the possibility that improved individual, patient-level decision-making is not the most effective strategy for improving end-of-life care and that improving routine practices may be more effective.

DESIGN

This paper reflects our efforts to synthesize findings from SUPPORT and other sources in order to explore our conceptual models, their consistency with the data, and their leverage for change.

RESULTS

Many of the assumptions underlying the model of improved decision-making are problematic. Furthermore, the results of SUPPORT suggest that implementing an effective intervention based on a normative model of shared decision-making can be quite difficult. Practice patterns and social expectations may be strong influences in shaping patients' courses of care. Innovations in system function, such as quality improvement or changing the financing incentives, may offer more powerful avenues for reform.

CONCLUSIONS

SUPPORT's intervention may have failed to have an impact because strong psychological and social forces underlie present practices. System-level innovation and quality improvement in routine care may offer more powerful opportunities for improvement.

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.
