Active management of the dying patient

Management of children with spinal muscular atrophy type 1 in Australia

AIMS

The study aims to: (i) estimate the prevalence of spinal muscular atrophy type 1 (SMA 1); (ii) describe what practices characterise end-of-life care of patients with SMA 1; and (iii) ascertain whether a consistent approach to the management of these patients exists in Australia.

METHODS

An audit of the Australasian pathology laboratories offering the diagnostic SMN1 deletion test was conducted for patients diagnosed with SMA in Australia for 2010 and 2011. In addition, a retrospective clinical audit was conducted in eight major Australian paediatric hospitals of the end-of-life care provided to children with confirmed SMA 1 from 2005 to 2010.

RESULTS

Thirty-five children were included in the clinical audit, accounting for an estimated 61% of children diagnosed with SMA 1 from 2005 to 2010. Twenty-six per cent were ventilated invasively, only two of whom were intubated after the diagnosis was confirmed. No children were ventilated long term (>90 days) or had a tracheostomy performed. Nasogastric tube feeding was a common measure to support adequate nutritional intake. Total parenteral nutrition, gastrostomy and fundoplication were not provided for any children. Conflict over end-of-life care decisions was documented in one instance, without the involvement of a guardianship tribunal.

CONCLUSION

There appears to be a consistent approach in the management of children with SMA 1 in Australia, which can be characterised as 'actively managed dying'. This study could contribute to the development of Australian consensus guidelines for the management of these children. These results also highlight a number of ethical issues related to the management of children with SMA 1.

Modified physiological and operative score for the enumeration of mortality and morbidity risk assessment model in general surgery

AIM: To establish a scoring system for predicting the incidence of postoperative complications and mortality in general surgery based on the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM), and to evaluate its efficacy.

METHODS: Eighty-four patients with postoperative complications or death and 172 patients without postoperative complications, who underwent surgery in our department during the previous 2 years, were retrospectively analyzed by logistic regression. Fifteen indexes were investigated including age, cardiovascular function, respiratory function, blood test results, endocrine function, central nervous system function, hepatic function, renal function, nutritional status, extent of operative trauma, and course of anesthesia. Modified POSSUM (M-POSSUM) was developed using significant risk factors with its efficacy evaluated.

RESULTS: The significant risk factors were found to be age, cardiovascular function, respiratory function, hepatic function, renal function, blood test results, endocrine function, nutritional status, duration of operation, intraoperative blood loss, and course of anesthesia. These factors were all included in the scoring system. There were significant differences in the scores between the patients with and without postoperative complications, between the patients died and survived with complications, and between the patients died and survived without complications. The receiver operating characteristic curves showed that the M-POSSUM could accurately predict postoperative complications and mortality.

CONCLUSION: M-POSSUM correlates well with postoperative complications and mortality, and is more accurate than POSSUM.

Communication of end-of-life decisions in European intensive care units

OBJECTIVE

To examine end-of-life (EOL) practices in European ICUs: who makes these decisions, how they are made, communication of these decisions and questions on communication between the physicians, nurses, patients and families.

DESIGN

Data collected prospectively on EOL decisions facilitated by a questionnaire including EOL decision categories, geographical regions, mental competency, information about patient wishes, and discussions with patients, families and health care professionals.

SETTING

37 European ICUs in 17 countries.

PATIENTS

ICU physicians collected data on 4,248 patients.

RESULTS

95% of patients lacked decision making capacity at the time of EOL decision and patient's wishes were known in only 20% of cases. EOL decisions were discussed with the family in 68% of cases. Physicians reported having more information about patients' wishes and discussions in the northern countries (31%, 88%) than central (16%, 70%) or southern (13%, 48%) countries. The family was more often told (88%) than asked (38%) about EOL decisions. Physicians' reasons for not discussing EOL care with the family included the fact that the patient was unresponsive to therapy (39%), the family was unavailable (28%), and the family was thought not to understand (25%).

CONCLUSIONS

ICU patients typically lack decision-making capacity, and physicians know patients' wishes in only 20% of EOL decisions. There were regional differences in discussions of EOL decisions with families and other physicians. In European ICUs there seems to be a need to improve communication.

Limitation of life support: Frequency and practice in a Hong Kong intensive care unit*

OBJECTIVE

To examine the frequency and the decision-making processes involved in limiting (withdrawing and withholding) life support therapy in critically ill Chinese patients in the intensive care unit.

DESIGN

Prospective survey of patients who had life support limited between April 1997 and March 1999.

SETTING

Medical and surgical intensive care unit of a teaching hospital.

PATIENTS

All patients admitted to the intensive care unit of the Prince of Wales Hospital who subsequently died and/or had life support limited. Brain-dead patients were excluded from analysis.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of 490 patients who died in the intensive care unit, limitation of life support occurred in 288 (58.8%). Relatives or patients requested limitation of life support in 32 cases (11%). The family and/or patient concurred with limitation of life support in 273 occasions (95%). Therapy was withheld in 30.8% and withdrawn in 28.0% of deaths. Therapy limited included inotropes, additional oxygen, and renal replacement therapy.

CONCLUSIONS

Limitation of therapy in dying Chinese patients occurs frequently in intensive care patients, and both patients and relatives concur with medical decisions to limit therapy in these patients. Withholding therapy rather than withdrawing therapy occurs more frequently than in Western populations.

Attitudes regarding organ donation from non-heart-beating donors

PURPOSE

To determine the attitudes toward organ donation from non-heart-beating cadaver donors in a sample of the general public and health care workers.

MATERIALS AND METHODS

A moderator-administered questionnaire was completed by members of the general public, recruited randomly from a professional consumer research group's database, and health care workers recruited from the same database, family practice clinics, and local hospitals. Two primary scenarios were tested: (1) patient in coma, not going to survive intensive care unit (ICU), and (2) patient lapsing in and out of consciousness, lifetime institutional care.

RESULTS

Sixty members of the general public and 68 health care workers completed the questionnaire. The majority of both groups were aware life support could be withdrawn in Scenario 1, however, significantly fewer were aware life support could also be withdrawn in Scenario 2 (83% general public vs 34% general public, P <.001 and 94% health care workers vs 78% health care workers, P =.012). Uncertainty in prognosis was cited as the primary concern. The issue of organ donation was directly linked with withdrawal of life support. The majority of both groups believed that organ donation would be permissible if further life support were deemed to be not in the patient's best interest because of poor short-term prognosis (94% health care workers and 98% general public for Scenario 1 and 87% health care workers and 81% general public for Scenario 2). The greatest difficulty arose in defining futility of care. Expected quality of life, patient's and family's values, opinions, and religious beliefs were felt to be most important in determining decisions regarding futility and withdrawal of life support. Physician beliefs and values were felt to influence decisions more than they should.

CONCLUSIONS

Both the general public and health care workers support the use of non-heart-beating cadaver donors once a decision has been made to withdraw life support. However, both groups raised concerns regarding how the decision to withdraw life support is made.

Synthesis of research and evidence on factors affecting the desire of terminally ill or seriously chronically ill persons to hasten death

Review of empirical studies indicates that suicide is more common in persons suffering from some physical illnesses (e.g., epilepsy, head injuries, Huntington's Chorea, gastrointestinal diseases, AIDS, and cancer), but other chronic diseases and disabilities have not been linked to increased suicide risk (e.g., blindness, senile dementia, multiple sclerosis, and other physical handicaps). The timing of increased suicide risk varies in different illnesses from early presymptomatic stages to the terminal phase. Difficulties in reliably determining when someone is “terminally ill” and problems of the competence of persons with a poor prognosis complicate empirical investigations of euthanasia, assisted suicide, and the desire to hasten death. The role of family and caregivers in end of life decisions needs further clarification. Researchers have found that pain and suffering and quality of life variables may be linked to the desire to die prematurely, particularly in cancer patients. Others find that clinical depression is a major factor. But, since depression is often present, we do not know why a small minority of depressed patients desire and choose to hasten death. Support for alternative hypotheses is examined, including the role of pre-morbid suicidality and depression, individual differences in coping strategies and indirect consequences of the illness. There is a need to clarify links between attitudes, which is the major variable studied, and actual behaviors and decisions. Furthermore, we need theoretical and empirical links between studies of suicide, which is linked to clinical depression and characterized by ambivalence and studies of euthanasia, which is often depicted as rational and with little ambivalence. Evaluative research should be conducted to determine if interventions to reduce the desire for a premature death by suicide, euthanasia, or assisted suicide are effective. In the light of this review, we present several considerations for those involved in proposing changes in public policy concerning euthanasia and assisted suicide.

Forgoing life support in western European intensive care units: the results of an ethical questionnaire

OBJECTIVE

To determine current views of European intensive care physicians regarding end-of-life decisions.

DESIGN

A questionnaire was sent to all physician members of the European Society of Intensive Care Medicine. All questionnaires were anonymous.

RESULTS

A total of 504 completed questionnaires from 16 western European countries were analyzed. Eighty-seven percent of the respondents were male. Forty-six percent of respondents said that intensive care unit admissions were generally or commonly affected by bed shortages, particularly in the south. Nevertheless, 73% of units frequently admit patients with no hope of survival, although only 33% of respondents felt that such patients should be admitted. Eighty percent of respondents felt that written do-not-resuscitate orders should be applied, but only 58% did so, with a wide variation according to country (from 8% in Italy to 91% in The Netherlands). Ninety-three percent of physicians sometimes withhold treatment from patients with no hope of a meaningful life, but withdrawal of treatment is less common. Forty percent of respondents said that they would deliberately administer large doses of drugs to such patients until death ensued. Forty-nine percent of respondents involved staff, patients, and family in end-of-life decisions. Forty-five percent of respondents felt that an ethics consultation was useful in such situations. Physicians in the countries of southern Europe were less likely than those in the north to apply do-not-resuscitate orders, withhold treatment, and discuss such issues with the patients. However, they were more likely to value the opinion of an ethics consultant.

CONCLUSIONS

Intensive care unit admissions are frequently limited by the availability of beds across Europe, particularly in the south and in the United Kingdom, yet 73% of intensivists still admit patients with no hope of survival. When treating patients with no hope of survival, 40% of intensivists will deliberately administer large doses of drugs until death ensues. There are interesting differences between what a physician actually does and what he or she believes should be done with regard to various ethical questions. Important differences in attitudes also exist between European countries.

Foregoing life-sustaining treatment in an Israeli ICU

OBJECTIVE

To determine whether physicians in Israel withhold and/or withdraw life-sustaining treatments.

DESIGN

A prospective, descriptive study of consecutively admitted patients. Patients were prospectively evaluated for diagnoses, types and reasons for foregoing life-sustaining treatment, mortality and times from foregoing therapy until mortality.

SETTING

A general intensive care unit of a university hospital in Israel.

RESULTS

Foregoing life-sustaining treatment occurred in 52 (13.5%) of 385 patients admitted and 5 (1%) had cardiopulmonary resuscitation. Withholding therapy occurred in 48 patients. Four patients with brain death had all treatments withdrawn. No patient had antibiotics, nutrition or fluids withheld or withdrawn. Time from foregoing therapy until death was 2.9 +/- 0.6 days. Thirty-one of 48 (65%) patients who had therapy withheld died within 48 h.

CONCLUSIONS

Withholding life-prolonging treatments is common in an Israeli intensive care unit whereas withdrawing therapy is limited to brain dead patients. Terminal patients die soon after withholding, even if the therapy is not withdrawn. Withholding treatments should be an option for patients and professionals who object to withdrawing therapies.

Issues of death and dying: the perspective of critical care nurses

A major shift in the care of terminally ill people, due to advances in technology, and the development of legislation regarding patient self-determination and autonomy, has occurred over recent years. Critical care nurses (CCNs) are involved daily in issues of death and dying and are very aware of the needs, fears and psychosocial issues of patients and their families. Professional associations see a legitimate role for nurses in assisting the dying to achieve a dignified death. For legislation, policies and guidelines surrounding end-of-life issues to be effective, and to assist nursing staff with these sensitive, often difficult concerns, it is important that data on the opinions and perspectives of CCNs be objectively obtained. In a study by the Department of Social and Preventive Medicine at the University of Queensland, questionnaires were sent to 1100 randomly sampled community members and almost 1200 health professionals (nurses, general practitioners and specialists), including 299 CCNs. The response rate of CCNs to a 30-page postal questionnaire was 79 per cent (n = 231), indicating those nurses' high levels of interest in and/or concern regarding this area. CCNs supported the use of advance directives, the appointment of proxies and the need for doctors and nurses to give sufficient medication to relieve pain, even if this hastened the death of the patient. In addition, CCNs, more than any other professional group, supported the right of the terminally ill patient to physician-assisted suicide or euthanasia, their responses being very similar to those of community members. CCNs clearly face issues which, from legal, medical and ethical viewpoints, cause them concern. In sharing their personal experiences, CCNs stressed the need for more communication between doctors and patients, as well as between doctors and nurses. In addition, CCNs saw a clear role for themselves as advocates for patients/families in the decision-making process.

Influence of alterations in foregoing life-sustaining treatment practices on a clinical sepsis trial. The HA-1A Sepsis Study Group

OBJECTIVES

To evaluate the timing of foregoing life-sustaining treatments in patients enrolled in a sepsis trial and to determine their influence on patient outcome and trial results.

DESIGN

Subset of patients in a prospective, randomized, double-blind, placebo-controlled study.

SETTING

Twenty-three academic medical centers.

PATIENTS

Enrolled patients who had life-sustaining therapies withheld or withdrawn.

MEASUREMENTS AND MAIN RESULTS

The number of patients, types of disorders and interventions, reasons, and timing of withholding and withdrawing life-sustaining treatments and their effect on mortality and trial results were assessed. Foregoing of life-sustaining therapies took place in 117 (22%) of 543 patients and occurred within 72 hrs of study drug administration in 38 (32%) patients. Withholding treatment (60%) was more common than withdrawing treatment (40%), but withdrawing treatment was more frequent (51%) than withholding treatment (20%) in the first 72 hrs of the trial (p < .01). Sixty-one (52%) patients had severe underlying disorders with a poor prognosis. The hospital mortality rate was 94% (of the 117 patients). The mean time (SEM) from withholding or withdrawing of treatment until death was 2.83 +/- 0.57 and 0.32 +/- 0.13 days, respectively (p < .001). Patients who had therapies foregone in the first 24, 48, and 72 hrs after receiving the study drug had higher mortality rates in the first 72 hrs (p < .01).

CONCLUSIONS

A substantial number of patients enrolled in a sepsis trial had severe underlying diseases and had foregoing of therapies early in the course of the trial, which led to a higher early mortality rate. Enrollment of patients in clinical trials with severe underlying disorders with a high likelihood of having therapies foregone may bias the potential for showing the efficacy of new therapeutic modalities.

Limitation of life support: frequency and practice in a London and a Cape Town intensive care unit

OBJECTIVES

To examine the frequency of limiting (withdrawing and withholding) therapy in the intensive care unit (ICU), the grounds for limiting therapy, the people involved in the decisions, the way the decisions are implemented and the patient outcome.

DESIGN

Prospective survey. Ethical approval was obtained.

SETTING

ICUs in tertiary centres in London and Cape Town.

PATIENTS

All patients who died or had life support limited.

INTERVENTIONS

Data collection only.

RESULTS

There were 65 deaths out of 945 ICU discharges in London and 45 deaths out of 354 ICU discharges in Cape Town. Therapy was limited in 81.5% and 86.7% respectively (p = 0.6) of patients who died. The mean ages of patients whose therapy was limited were 60.2 years and 51.9 years (p = 0.014) and mean APACHE II scores 18.5 and 22.6 (p = 0.19) respectively. The most common reason for limiting therapy in both centres was multiple organ failure. Both medical and nursing staff were involved in most decisions, which were only implemented once wide consensus had been reached and the families had accepted the situation. Inotropes, ventilation, blood products, and antibiotics were most commonly withdrawn. The mean time from admission to the decision to limit therapy was 11.2 days in London and 9.6 days in Cape Town. The times to outcome (death in all patients) were 13.2 h and 8.1 h respectively.

CONCLUSIONS

Withdrawal of therapy occurred commonly, most often because of multiple organ failure. Wide consensus was reached before a decision was made, and the time to death was generally short.

The clinical management of dying patients receiving mechanical ventilation. A survey of physician practice

OBJECTIVE

Despite mechanical ventilation's widespread use, there is scant literature to guide the management of patients receiving mechanical ventilatory assistance who are foregoing life-sustaining treatment. This survey was conducted to characterize physician treatment of such patients.

DESIGN

Surveys were mailed to 513 randomly selected critical care physicians and returned by 308 (60 percent); 273 respondents were involved in ventilator management; all others were excluded.

PARTICIPANTS

Forty percent of respondents were internists, 28 percent were surgeons, 16 percent were pediatricians, and 11 percent were anesthesiologists; 85 percent of physicians were board eligible/certified in a critical care subspecialty.

RESULTS

Fifteen percent of respondents almost never withdrew ventilators from dying patients foregoing life-sustaining treatment; 37 percent did so less than half the time. Twenty-six percent of physicians believed there was a moral difference between withholding and withdrawing ventilators. Of physicians who withdrew ventilators, 33 percent preferred terminal weaning, 13 percent preferred extubation, and the remainder used both methods. Reasons for preferring extubation included the directness of the action (72 percent), family perceptions (34 percent), and patient comfort (34 percent). Reasons for preferring terminal weaning included patient comfort (65 percent), family perceptions (63 percent), and the belief that terminal weaning was less active (49 percent). Morphine and benzodiazepines were used frequently by 74 percent (morphine) and 53 percent (benzodiazepines) of physicians when withdrawing ventilators; 6 percent used paralytics at least occasionally.

CONCLUSIONS

There is significant variation in the care of dying patients receiving mechanical ventilatory assistance, with 15 percent of respondents almost never withdrawing ventilators from such patients. Two very different methods of ventilator withdrawal each have advocates, yet rationales of patient comfort and family perceptions are matters of individual experience, absent published studies. The occasional use of paralytics during ventilator withdrawal raises concern about current practice.

The significance for critical care nurses of the "dying with dignity" legislation

This paper examines the potential contribution of the critical care nurse to ethical decisions made with respect to the dying with dignity legislation. The literature to date on ethics in nursing has largely focused on increasing nurses awareness thereby encouraging their contribution to the ethical decision-making process. By accentuating the 'art of nursing' where forms of knowing encompass an understanding of the patient's experience, this article describes the unique contribution that the nurse can make to the specific area of 'dying with dignity' in the acute care setting. On a theoretical level this knowledge is invaluable as it ensures a range of constituents are accommodated in this decision-making process, however, in practice this ideal is not readily attainable. Firstly, tradition seeks to curtail the value of this form of nursing knowledge in the decision-making process and secondly, nurses need to recognise their own prejudices in order to make an appropriate contribution to this legitimate body of knowledge.
