'Do not resuscitate' orders. Incidence and implications in a medical-intensive care unit

Assessment of Discordance Between Surrogate Care Goals and Medical Treatment Provided to Older Adults With Serious Illness

IMPORTANCE

An important aspect of high-quality care is ensuring that treatments are in alignment with patient or surrogate decision-maker goals. Treatment discordant with patient goals has been shown to increase medical costs and prolong end-of-life difficulties.

OBJECTIVES

To evaluate discordance between surrogate decision-maker goals of care and medical orders and treatments provided to hospitalized, incapacitated older patients.

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study included 363 patient-surrogate dyads. Patients were 65 years or older and faced at least 1 major medical decision in the medical and medical intensive care unit services in 3 tertiary care hospitals in an urban Midwestern area. Data were collected from April 27, 2012, through July 10, 2015, and analyzed from October 5, 2018, to December 5, 2019.

MAIN OUTCOMES AND MEASURES

Each surrogate's preferred goal of care was determined via interview during initial hospitalization and 6 to 8 weeks after discharge. Surrogates were asked to select the goal of care for the patient from 3 options: comfort-focused care, life-sustaining treatment, or an intermediate option. To assess discordance, the preferred goal of care as determined by the surrogate was compared with data from medical record review outlining the medical treatment received during the target hospitalization.

RESULTS

A total of 363 dyads consisting of patients (223 women [61.4%]; mean [SD] age, 81.8 [8.3] years) and their surrogates (257 women [70.8%]; mean [SD] age, 58.3 [11.2] years) were included in the analysis. One hundred sixty-nine patients (46.6%) received at least 1 medical treatment discordant from their surrogate's identified goals of care. The most common type of discordance involved full-code orders for patients with a goal of comfort (n = 41) or an intermediate option (n = 93). More frequent in-person contact between surrogate and patient (adjusted odds ratio [AOR], 0.43; 95% CI, 0.23-0.82), patient residence in an institution (AOR, 0.44; 95% CI, 0.23-0.82), and surrogate-rated quality of communication (AOR, 0.98; 95% CI, 0.96-0.99) were associated with lower discordance. Surrogate marital status (AOR for single vs married, 1.92; 95% CI, 1.01-3.66), number of family members involved in decisions (AOR for ≥2 vs 0-1, 1.84; 95% CI, 1.05-3.21), and religious affiliation (AOR for none vs any, 4.87; 95% CI, 1.12-21.09) were associated with higher discordance.

CONCLUSIONS AND RELEVANCE

This study found that discordance between surrogate goals of care and medical treatments for hospitalized, incapacitated patients was common. Communication quality is a modifiable factor associated with discordance that may be an avenue for future interventions.

Protocol for a randomised trial of an interprofessional team-delivered intervention to support surrogate decision-makers in ICUs

INTRODUCTION

Although shortcomings in clinician-family communication and decision making for incapacitated, critically ill patients are common, there are few rigorously tested interventions to improve outcomes. In this manuscript, we present our methodology for the Pairing Re-engineered Intensive Care Unit Teams with Nurse-Driven Emotional support and Relationship Building (PARTNER 2) trial, and discuss design challenges and their resolution.

METHODS AND ANALYSIS

This is a pragmatic, stepped-wedge, cluster randomised controlled trial comparing the PARTNER 2 intervention to usual care among 690 incapacitated, critically ill patients and their surrogates in five ICUs in Pennsylvania. Eligible subjects will include critically ill patients at high risk of death and/or severe long-term functional impairment, their main surrogate decision-maker and their clinicians. The PARTNER intervention is delivered by the interprofessional ICU team and overseen by 4-6 nurses from each ICU. It involves: (1) advanced communication skills training for nurses to deliver support to surrogates throughout the ICU stay; (2) deploying a structured family support pathway; (3) enacting strategies to foster collaboration between ICU and palliative care services and (4) providing intensive implementation support to each ICU to incorporate the family support pathway into clinicians' workflow. The primary outcome is surrogates' ratings of the quality of communication during the ICU stay as assessed by telephone at 6-month follow-up. Prespecified secondary outcomes include surrogates' scores on the Hospital Anxiety and Depression Scale, the Impact of Event Scale, the modified Patient Perception of Patient Centredness scale, the Decision Regret Scale, nurses' scores on the Maslach Burnout Inventory, and length of stay during and costs of the index hospitalisation.We also discuss key methodological challenges, including determining the optimal level of randomisation, using existing staff to deploy the intervention and maximising long-term follow-up of participants.

ETHICS AND DISSEMINATION

We obtained ethics approval through the University of Pittsburgh, Human Research Protection Office. The findings will be published in peer-reviewed journals.

Limitation of Life-Sustaining Care in the Critically Ill: A Systematic Review of the Literature

When life-sustaining treatments (LST) are no longer effective or consistent with patient preferences, limitations may be set so that LSTs are withdrawn or withheld from the patient. Many studies have examined the frequency of limitations of LST in intensive care unit (ICU) settings in the past 30 years. This systematic review describes variation and patient characteristics associated with limitations of LST in critically ill patients in all types of ICUs in the United States. A comprehensive search of the literature was performed by a medical librarian between December 2014 and April 2017. A total of 1,882 unique titles and abstracts were reviewed, 113 were selected for article review, and 36 studies were fully reviewed. Patient factors associated with an increased likelihood of limiting LST included white race, older age, female sex, poor preadmission functional status, multiple comorbidities, and worse illness severity score. Based on several large, multicenter studies, there was a trend toward a higher frequency of limitation of LST over time. However, there is large variability between ICUs in the proportion of patients with limitations and on the proportion of deaths preceded by a limitation. Increases in the frequency of limitations of LST over time suggests changing attitudes about aggressive end-of-life-care. Limitations are more common for patients with worse premorbid health and greater ICU illness severity. While some differences in the frequency of limitations of LST may be explained by personal factors such as race, there is unexplained wide variability between units.

Duration of withdrawal of life support in the intensive care unit and association with family satisfaction

RATIONALE

Most deaths in the intensive care unit (ICU) involve withholding or withdrawing multiple life-sustaining therapies, but little is known about how to proceed practically and how this process affects family satisfaction.

OBJECTIVES

To examine the duration of life-support withdrawal and its association with overall family satisfaction with care in the ICU.

METHODS

We studied family members of 584 patients who died in an ICU at 1 of 14 hospitals after withdrawal of life support and for whom complete medical chart and family questionnaires were available.

MEASUREMENTS AND MAIN RESULTS

Data concerning six life-sustaining interventions administered during the last 5 days of life were collected. Families were asked to rate their satisfaction with care using the Family Satisfaction in the ICU questionnaire. For nearly half of the patients (271/584), withdrawal of all life-sustaining interventions took more than 1 day. Patients with a prolonged (>1 d) life-support withdrawal were younger, stayed longer in the ICU, had more life-sustaining interventions, had less often a diagnosis of cancer, and had more decision makers involved. Among patients with longer ICU stays, a longer duration in life-support withdrawal was associated with an increase in family satisfaction with care (P = 0.037). Extubation before death was associated with higher family satisfaction with care (P = 0.009).

CONCLUSIONS

Withdrawal of life support is a complex process that depends on patient and family characteristics. Stuttering withdrawal is a frequent phenomenon that seems to be associated with family satisfaction. Extubation before death should be encouraged if possible.

Prospective analysis of life-sustaining therapy discussions in the surgical intensive care unit: a housestaff perspective

BACKGROUND

Prospective data addressing end-of-life care in the surgical ICU are lacking. We determined factors surrounding life-sustaining therapy discussions (LSTDs) in our surgical ICU as experienced by housestaff.

STUDY DESIGN

Housestaff were interviewed daily about the occurrence of an LSTD between themselves and either a patient or surrogate. Patients for whom at least one LSTD occurred were compared with patients for whom an LSTD never occurred. Housestaff also completed a standardized questionnaire that captured events surrounding each LSTD.

RESULTS

Eighty LSTDs occurred among 50 patients. Lack of decision-making capacity (p = 0.04), age (p = 0.02), and acuity (p = 0.01) predicted independently the occurrence of an LSTD. Housestaff were significantly more likely to both report recent clinical deterioration (p < 0.01) and to assign a worse prognosis (p < 0.01) to patients for whom an LSTD occurred. Housestaff initiated the majority of LSTDs (70.0%) and usually did so because of clinical deterioration (60.7%); patient surrogates were most commonly believed to initiate LSTDs because of lack of improvement (60.1%). In no instance did a patient initiate an LSTD. For 39 of 50 patients (78.0%), changes in end-of-life care plans were eventually enacted as proposed originally. Housestaff reported that the likelihood of enactment depended on both the preexisting end-of-life care plan and the proposed change in end-of-life care plan.

CONCLUSIONS

Age, acuity, and lack of decision-making capacity were the most important factors involved in the initiation of an LSTD. Housestaff reported that they initiated LSTDs for different reasons and proposed different end-of-life care plans relative to both patients and their surrogates. These disparities can contribute to failed enactment of proposed changes in end-of-life care plans.

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.

Studying communication about end-of-life care during the ICU family conference: Development of a framework

PURPOSE

Family-clinician communication in the intensive care unit (ICU) about withholding and withdrawing life support occurs frequently, yet few data exist to guide clinicians in its conduct. The purpose of this study was to develop an understanding of the way this communication is currently conducted.

METHODS

We identified family conferences in the ICUs of 4 Seattle-area hospitals. Conferences were eligible if the physician leading the conference believed that discussion about withholding or withdrawing life support or the delivery of bad news was likely to occur and if all conference participants consented to participate. Fifty conferences were audiotaped, transcribed, and analyzed by using the principles of grounded theory.

RESULTS

We developed 2 frameworks for describing and understanding this communication. The first framework describes communication content, including introductions, information exchange, discussions of the future, and closings. The second framework describes communication styles and support provided to families and other clinicians and includes a variety of techniques such as active listening, acknowledging informational complexity and emotional difficulty of the situation, and supporting family decision making. These frameworks identify what physicians discuss, how they present and respond to issues, and how they support families during these conferences.

CONCLUSIONS

This article describes a qualitative methodology to understand clinician-family communication during the ICU family conference concerning end-of-life care and provides a frame of reference that may help guide clinicians who conduct these conferences. We also identify strategies clinicians use to improve communication and enhance the support provided. Further analyses and studies are needed to identify whether this framework or these strategies can improve family understanding or satisfaction or improve the quality care in the ICU.

Sociodemographic factors and the assignment of do-not-resuscitate orders in patients with acute myocardial infarctions

OBJECTIVES

This study examined the impact of sociodemographic and clinical factors, measured at the individual or ecological (zip code) level, on the assignment of do-not-resuscitate (DNR) orders.

DESIGN

This was a retrospective study (analysis of secondary data).

SUBJECTS

We used a probability sample of 974 patients admitted to 30 medium to large California hospitals with acute myocardial infarctions in 1990 to 1991; the sample was originally designed to validate risk adjustment with administrative data.

METHODS

Multivariate logistic regression was used to adjust DNR assignment for age, gender, race, probability of death, functional impairments, payment source, hospital teaching status, and ecological measures of educational attainment, home ownership, and income.

RESULTS

DNR assignment was inversely associated with black race and positively associated with age, probability of death, cognitive impairment, and poor nutritional status. When the probability of death was very low, DNR orders were assigned less frequently to men than to women (odds ratio [OR], 0.4; 95% confidence interval [CI], 0.2 to 0.7 at probability of death = 0.10). However, men were significantly more likely to receive a DNR order than women when the probability of death was very high (OR, 4.4; 95% CI, 1.2 to 16.3 at probability of death = 0.90).

CONCLUSIONS

Older, white, sicker, or functionally impaired patients receive DNR orders more often than younger, black, healthier, or functionally intact patients do. Adjusting for these factors, DNR assignment is associated with gender through an interaction involving the probability of death. Future studies should reexamine the impact of these factors on DNR assignment and explore the role of patient values and patient-physician communication barriers.

Increased risk of death in patients with do-not-resuscitate orders

BACKGROUND

Whereas studies have shown higher mortality rates in patients with do-not-resuscitate (DNR) orders, most have not accounted for confounding factors related to the use of DNR orders and/or factors related to the risk of death.

OBJECTIVE

To determine the relationship between the use of DNR orders and in-hospital mortality, adjusting for severity of illness and other covariates.

DESIGN

Retrospective cohort study.

PATIENTS

There were 13,337 consecutive stroke admissions to 30 hospitals in 1991 to 1994.

MEASURES

To decrease selection bias, propensity scores reflecting the likelihood of a DNR order were developed. Scores were based on nine demographic and clinical variables independently related to use of DNR orders. The odds of death in patients with DNR orders were then determined using logistic regression, adjustment for propensity scores, severity of illness, and other factors.

RESULTS

DNR orders were used in 22% (n = 2,898) of patients. In analyses examining DNR orders written at any time during hospitalization, unadjusted in-hospital mortality rates were higher in patients with DNR orders than in patients without orders (40% vs. 2%, P<0.001); the adjusted odds of death was 33.9 (95% CI, 27.4-42.0). The adjusted odds of death remained higher in analyses that only considered orders written during the first 2 days (OR 3.7; 95% CI, 3.2-4.4) or the first day (OR 2.4; 95% CI, 2.0-2.9). In stratified analyses, adjusted odds of death tended to be higher in patients with lower propensity scores.

CONCLUSION

The risk of death was substantially higher in patients with DNR orders after adjusting for propensity scores and other covariates. Whereas the increased risk may reflect patient preferences for less intensive care or unmeasured prognostic factors, the current findings highlight the need for more direct evaluations of the quality and appropriateness of care of patients with DNR orders.

Changes over time in the use of do not resuscitate orders and the outcomes of patients receiving them

OBJECTIVES

Do not resuscitate (DNR) orders are increasingly common, though there has been little evaluation of their changing use. The authors contrasted the use and outcomes of DNR orders for nationally representative samples of Medicare patients hospitalized with specific diagnoses in 1981 to 1982 and 1985 to 1986.

METHODS

Using ordinary least squares regression to adjust for patient and hospital characteristics, the authors compared use, timing and predictors of DNR orders, and survival to hospital discharge of patients with DNR orders between the two time periods.

RESULTS

After adjustment for sickness at admission and for patient and hospital factors, more patients received DNR orders in 1985 to 1986 than in 1981 to 1982 (13% versus 10%, P < 0.001), with most of the increase among patients with the greatest sickness at admission. Disparity in DNR order use by age, diagnosis, functional status, preadmission residence, and gender found in 1981 to 1982 was still present in 1985 to 1986. DNR orders were written earlier in hospitalization during the latter time period. Patients with DNR orders were more likely to survive to hospital discharge in 1985 to 1986 than in 1981 to 1982 (44% versus 36%, P = 0.001), but their 30-day survival did not differ.

CONCLUSIONS

Although use increased, disparities in DNR order assignment persisted in these 1980s data. Examination is needed into whether these differences persist and whether they reflect patient preferences. Systems should be developed to preserve and review the preferences of the increasing number of patients discharged after in-hospital DNR orders.

Care for the patient with AIDS in the ICU: outcomes and ethics

HIV infection and AIDS are common diagnoses in many intensive care units (ICUs) in the United States. Although Pneumocystis carinii currently represents only one quarter of all diagnoses for which HIV-infected persons are admitted to the ICU, it is the disease with the most clinically applicable outcome data and, therefore, is a model for ethical decision-making regarding patients with HIV infection in the ICU. Despite advances in diagnosis and treatment of HIV-related P. carinii, recent studies show that only 20% to 25% of the patients with acute respiratory failure survive to hospital discharge. Although many clinical markers correlate with survival, none of the individual markers or prediction scoring systems have the accuracy needed in clinical practice. One goal of predicting outcome in the ICU is to aid both the patient and the physician in making decisions about when to pursue aggressive therapy and when to withhold or withdraw such therapy. Because our ability to predict outcome is limited, advance directives and communication with patients and families about end-of-life medical care are of utmost importance. Even though it is not always possible for patients to predict, in advance, what they would want done in various hypothetical health care scenarios, quality communication between physicians, patients, and families with realistic discussion of outcomes and maintenance of hope and dignity can facilitate decisions about the use of intensive care for patients with AIDS.

Ethics in treatment decisions during out-of-hospital resuscitation

Paramedics in Oslo are allowed to make decisions about withholding or terminating cardiopulmonary resuscitation (CPR). In order to elicit the criteria used, 35 paramedics and nine doctors were interviewed after 70 episodes of cardiac arrest outside-of-hospital. CPR was not attempted in 21 patients, and discontinued in the field in 28 patients. Spontaneous circulation was restored in 15 patients, and six patients were transported to hospital with ongoing CPR. Both prognostic and ethical criteria were used without a clear borderline. Signs considered to indicate good prognosis such as VF, gaps, contracted pupils, or normal skin color always led to start of CPR. Bystander CPR was continued even when the professional thought the effort was futile, partly to encourage the bystanders. The social status of the patient did not affect the decisions, and advanced age only when combined with important criteria such as arrest times or the relatives' wishes. The only apparent difference between paramedics and doctors was that the reputation of the EMS system influenced only the paramedics. All paramedics had long experience which influenced their decisions, which were based on a rapidly composed broad picture of the patient's situation. All presented serious ethical considerations about life and death indicating that they did not make these decisions lightly.

Contributions of empirical research to medical ethics

Empirical research pertaining to cardiopulmonary resuscitation (CPR), clinician behaviors related to do-not-resuscitate (DNR) orders and substituted judgment suggests potential contributions to medical ethics. Research quantifying the likelihood of surviving CPR points to the need for further philosophical analysis of the limitations of the patient autonomy in decision making, the nature and definition of medical futility, and the relationship between futility and professional standards. Research on DNR orders has identified barriers to the goal of patient involvement in these life and death discussions. The initial data on surrogate decision making also points to the need for a reexamination of the moral basis for substituted judgment, the moral authority of proxy decision making and the second-order status of the best interests standard. These examples of empirical research suggest that an interplay between empirical research, ethical analysis and policy development may represent a new form of interdisciplinary scholarship to improve clinical medicine.

Nurses' perceptions of the support of patient autonomy in do-not-resuscitate (DNR) decisions

This replication of Ott's study [Ott, B. (1986). An Ethical Problem Facing Nurses: The Support of Patient Autonomy in the Do Not Resuscitate Decision. University Microfilms International, Dissertation, Texas Women's University] and McLaughlin et al.'s study [McLaughlin, T., Brown, O. and Herman, J. (1988). Nurses' Perception of the Support of Patient Autonomy in Do Not Resuscitate Situations. Unpublished Research Report] explored hospital staff nurses' perceptions of their role in supporting patient autonomy in the do-not-resuscitate (DNR) decision. One-hundred and sixty-five registered nurses (RNs) participated: 93 from the Veterans Administration Medical Center and 72 from a private non-profit hospital. Ott's questionnaire had four hypothetical cases in which a DNR decision would probably be made with three questions about whose opinion would most support patient autonomy and whose opinion would actually be regarded as the most appropriate for making the DNR decision. Seventy per cent of perceptions of the person whose decision would be best able to support the patient's autonomy in the DNR decision and 51% of the people perceived to actually be deemed most appropriate to make the DNR decision were consistent with Ott's DNR Decision Model.

The negotiation of death: clinical decision making at the end of life

The ability of medical science to prolong biological life through the use of technology raises the question of how far physicians should go in treating the terminally ill patient. In clinical decision making involving the dying patient, physicians, patients and families bring various perceptions and interpretations to the situation. These different realities must be negotiated in order to define the meaning of the situation and the meaning of various medical technologies. The patient's demise becomes a negotiated death, a bargaining over how far medical technology should go in prolonging life or in prolonging death. A case study of the process of ethical decision making in the foregoing of life-supporting therapy in an intensive care setting is presented and analyzed. The decision making process in this case follows a 'cascade' pattern rather than a controlled, reflective model. While ethicists view the withholding and withdrawing of life-supporting treatment as morally equivalent, physicians tend to make a distinction based on the perceived locus of moral responsibility for the patient's death. In the author's interpretation the moral responsibility for the patient's death by withdrawing treatment is shared with family members, while the moral responsibility for the patient's death by withholding treatment is displaced to the patient. The author suggests that an illusion of choice in medical decision making, as offered by the physician, begins a negotiation of meanings that allows a sharing of moral responsibility for medical failure and its eventual acceptance by patient, family and physician alike.

Shades of blue: the negotiation of limited codes by medical residents

One of the most difficult decisions facing physicians in contemporary medical practice is whether to initiate or withhold cardiopulmonary resuscitation (CPR) for patients who are critically ill. Because of the problems surrounding these decisions, hospital guidelines have recently been developed for the appropriate use of do-not-resuscitate (DNR) orders. Despite the establishment of these guidelines, problems with the application of DNR orders remain. This study examines one strategy used by internal medicine resident physicians to cope with the problematic nature of decisions regarding resuscitation--the use of partial or slow resuscitation attempts, known as 'limited codes.' It analyzes how these code efforts play a role within the context of resident work by enabling residents to circumvent ethical and practical dilemmas created by the circumstances of their clinical practice.

Perception of "No Code" and the Role of the Nurse

CPR is now the rule rather than the exception and death is often viewed as the ultimate failure in modern medicine, rather than the final event of the natural life process (Stevens, 1986). The "No Code" concept has created a major dilemma in health care. An interagency collaborative study was conducted to ascertain the perceptions of nurses, physicians, and laypersons about this issue. This article deals primarily with the nurse's role and perceptions of the "No Code" issue. The comparison of nurses' perceptions with those of physicians and laypersons is unique to this study. Based on this research, suggestions are presented that will assist nursing educators and health care professionals in managing this complex dilemma.

Discussions regarding aggressive care with critically ill patients

Protocols concerning orders not to resuscitate have come into existence recently in order to facilitate decisions regarding resuscitation and to ensure that patient's rights to participate in such decisions are preserved. Prior to the do-not-resuscitate (DNR) decision is the decision whether to discuss the issue of resuscitation with the patient at all. To determine how frequently physicians discuss this issue with their patients, the authors gathered information on all 611 patients admitted to the medical intensive care unit (MICU) or the cardiac care unit (CCU) at a tertiary care teaching hospital over a nine-month period. They found that the issue was discussed with only 10.8% of patients or their families on admission of the patients to these units. Such discussions occurred more frequently with older patients, those who were more severely ill or were estimated to have worse prognoses, those with poor intellectual function, and those admitted to the MICU rather than the CCU.

Consultation-liaison psychiatry and the teaching of ethics

Medicine has undergone a technological explosion which presents physicians with an increased need to make difficult ethical decisions. This has been met by an equivalent development in American medical schools of efforts to teach the ethics of medical practice. The courses vary widely from school to school. It is recommended that a core curriculum of basic theory be taught in preclinical years, followed by case-centered teaching in clinical years and residency. Only with real cases can the influence of the doctor-patient relationship be appreciated. Teaching of ethics cannot be divorced from the clinical reality of the doctor-patient relationship. The emotional needs of both enter into all decisions. It is offered that consultation-liaison psychiatry, which addresses the needs of both, is an ideal focus for such teaching.
