The role of critical care nurses in euthanasia and assisted suicide.
BACKGROUND: Euthanasia and assisted suicide has received considerable attention recently in medical literature, public discussion, and proposed state legislation. Almost all the discussion in this area has focused on the role of physicians. However, nurses--especially critical care nurses--may be in a special position to understand the wishes of patients and to act on this understanding. METHODS: I mailed a survey to 1600 critical care nurses in the United States, asking them to describe anonymously any requests from patients, family members or others acting for patients (surrogates), or physicians to perform euthanasia or assisted suicide, as well as their own practices. RESULTS: Of the 1139 nurses who responded (71 percent), 852 said they practices exclusively in intensive care units for adults in the United States. Of these 852 nurses, 141 (17 percent) reported that they had received requests from patients or family members to perform euthanasia or assist in suicide; 129 (16 percent of those for whom data were available) reported that they had engaged in euthanasia; and an additional 36 (4 percent) reported that they had hastened a patient's death by only pretending to provide life-sustaining treatment ordered by a physician. Some nurses reported engaging in these practices without the request for advance knowledge of physicians or others. The method of euthanasia most commonly described was the administration of a high dose of an opiate to a terminally ill patient. CONCLUSIONS: As public debate continues about euthanasia and assisted suicide, some critical care nurses in the United States are engaging in the practice.

Cost-effectiveness analysis in a setting of budget constraints--is it equitable?
BACKGROUND: One of the promises of cost-effective analysis is that it can demonstrate how to maximize health benefits attainable within a specific limited budget. Many people argue, however, that when there are budget limitations, the use of cost-effectiveness analysis leads to health care policies that are inequitable. METHODS: We asked prospective jurors, medical ethicists, and experts in medical decision making to choose between two screening tests for a population at low risk for colon cancer. One test was more cost effective than the other but because of budget constraints was too expensive to be given to everyone in the population. With the use of the more effective test for only half the population, 1100 lives could be saved at the same cost as that of saving 1000 lives with the use of the less effective test for the entire population. RESULTS: Fifty-six percent of the prospective jurors, 53 percent of the medical ethicists, and 41 percent of the experts in medical decision making recommended offering the less effective screening test to everyone, even though 100 more lives would have been saved by offering the more expensive test to only a portion of the population. Most of the study participants justified this recommendation on the basis of equity. A smaller number stated either that it was not politically feasible to offer a test to only half the population or that the additional benefit of the more expensive test (100 more lives saved) was too small to justify offering it to only a portion of the public. CONCLUSIONS: People place greater importance on equity than is reflected by cost-effectiveness analysis. Even many experts in medical decision making -- those often responsible for conducting cost-effectiveness analyses -- expressed discomfort with some of its implications. Basing health care priorities on cost effectiveness may not be possible without incorporating explicit considerations of equity into cost-effectiveness analyses or the process used to develop health care policies on the basis of such analyses.

Classifying general medicine readmissions. Are they preventable? Veterans Affairs Cooperative Studies in Health Services Group on Primary Care and Hospital Readmissions.
OBJECTIVES: To describe a new quality assessment method used to classify the preventability of hospitalization in terms of patient, clinician, or system factors. DESIGN: The instrument was developed in two phases. Phase 1 was a prospective comparison of admitting residents' and their attending physicians' classifications of the perceived preventability of consecutive admissions to one Veterans Affairs Medical Center (VAMC) excluding admissions to the intensive care unit (ICU). In phase 2, a panel of 10 physicians rated 811 abstracted records of readmissions from nine VAMCs. SETTING: Nine VAMCs across the United States with varying degrees of university hospital affiliation. PATIENTS: Phase 1, 156 patients admitted to the general medicine service at the Durham VAMC. Phase 2, 514 patients accounting for 811 readmissions within 6 months of a general medicine service discharge at nine VAMCs. MEASUREMENTS AND MAIN RESULTS: Physicians used a checklist to record the reason for hospitalization, the preventability of the hospitalization, and, if preventable, a reason defining preventability, which was classified in terms of system, clinician, and patient factors. In phase 2, two physician panelists assessed preventability for each chart. When two panelists disagreed on the preventability of hospitalization, a third panelist, blind to the original assessments, rated the chart. In phase 1, residents and attending physicians rated 33% and 34% of admissions as preventable (kappa = 0.41), respectively. In phase 2, 277 (34%) of 811 readmissions were deemed preventable. Intraobserver accuracy for the assessment of preventability was 96% (kappa = 0.89). interobserver accuracy was 73% (kappa = 0.43). Hospital system factors accounted for 37% of preventable readmissions, clinician factors for 38%, and patient factors for 21%. The nine hospitals differed markedly in their profile of reasons for preventable readmissions (p = .005). CONCLUSIONS: Using a new method of determining the preventability of hospitalizations, we identified several factors that might avert hospitalizations. Focusing efforts to identify preventable hospitalizations may yield better methods for managing patients' total health care needs; however, the content of those efforts will vary by institution.

Cognitive processes and the decisions of some parents to forego pertussis vaccination for their children.
Public health analyses suggest that, in spite of the possibility that pertussis vaccine may cause rare cases of neurological injury, catastrophic risks to individual children are lower if they are vaccinated. A number of parents, however, choose not to vaccinate their children. The purpose of this study was to investigate the decision processes of some parents who choose to vaccinate and some parents who choose not to do so. Surveys were mailed to 500 randomly selected subscribers of Mothering magazine. Two hundred and ninety-four completed questionnaires were returned (59%). In addition to well-recognized factors in vaccination decisions, perceived dangers of the vaccine, and of the disease and susceptibility to the disease, several cognitive processes not previously considered in vaccination decision studies were found to be important predictors in this population of parents: perceived ability to control children's susceptibility to the disease and the outcome of the disease; ambiguity or doubts about the reliability of vaccine information; a preference for errors of omission over errors of commission; and recognition that if many other children are vaccinated, the risk to unvaccinated children may be lowered. Although perhaps most cases of undervaccination for pertussis reflect more general problems of health care access, some parents choose to forego vaccination for their children for other reasons. Traditional risk-benefit arguments alone will be unlikely to persuade these parents to reassess their decisions. Efforts to increase childhood vaccination must incorporate an understanding of the cognitive processes that help drive these decisions.

Why do physicians prefer to withdraw some forms of life support over others? Intrinsic attributes of life-sustaining treatments are associated with physicians' preferences.
Some physicians caring for critically ill patients have preferences for withdrawing some forms of life support over others, even after the decision to withdraw life support has already been made. Past research has attempted to explain these preferences by variations in clinical circumstances. The authors wondered whether differences in the forms of life support themselves might be important, and whether these differences would reveal implicit goals that physicians attempt to achieve. Four hundred fifty-six university-affiliated internists were surveyed and their rank-ordered preferences for withdrawing eight different forms of life support were assessed. The authors then sought to explain these preferences on the basis of intrinsic characteristics of the eight forms of life support determined by an expert panel of critical care physicians. In general, the physicians studied prefer to withdraw forms of life support that are scarce, expensive, invasive, artificial, unnatural, emotionally taxing, high technology, and rapidly fatal when withdrawn. They prefer not to withdraw forms of therapy that require continuous rather than intermittent administration, and forms of therapy that cause pain when withdrawn. Even when a decision has been made to withdraw life-sustaining treatment from a patient, many physicians have preferences for the manner in which this is accomplished. These preferences may reflect perceived intrinsic characteristics of different forms of life support that are consistent across physicians.

Individual choice in spending accounts. Can we rely on employees to choose well?
Flexible spending accounts (FSA) represent a current health care financing tool that may become an important component of incremental health care reform. Because FSAs require employees to make financial contributions based on anticipated health care needs, contribution decisions are likely to be subject to many of the errors made in other insurance decisions. The authors analyzed the benefits selections, benefits forms completion, and FSA contribution levels of approximately 9,500 employees of the University of Pennsylvania from 1987 to 1992. Default and repeat choice trends characterize the completion of benefits forms and the reselection of health insurance options by employees. Despite the economic benefits of contributing to an FSA, only 14% of employees contributed in any one year and 73% never made a contribution. Multivariate models of these contributions fail to demonstrate the importance of what ought to be relevant influences in contribution decisions (for example, age, income, family status, or underlying health insurance). Whereas most FSA decisions are characterized by default contributions of $0, employees who contribute in one year are most likely to contribute exactly the same amount the next year, even when other circumstances change. The pervasiveness of these patterns raises concerns that health care reform plans that rely on financial incentives at the consumer level--for example, proposed medical saving accounts--will be inefficient.

Genetic screening for reproductive planning: methodological and conceptual issues in policy analysis.
OBJECTIVES: This paper explores several critical assumptions and methodological issues arising in cost-effectiveness analyses of genetic screening strategies in the reproductive setting. METHODS: Seven issues that arose in the development of a decision analysis of alternative strategies for cystic fibrosis carrier screening are discussed. Each of these issues required a choice in technique. RESULTS: The presentations of these analyses frequently mask underlying assumptions and methodological choices. Often there is no best choice. In the case of genetic screening in the reproductive setting, these underlying issues often touch on deeply felt human values. CONCLUSIONS: Space limitations for published papers often preclude explaining such choices in detail; yet these decisions determine the way the results should be interpreted. Those who develop these analyses need to make sure that the implications of important assumptions are understood by the clinicians who will use them. At the same time, clinicians need to enhance their understanding of what these models truly mean and how they address underlying clinical, ethical, and economic issues.

The role of employee flexible spending accounts in health care financing.
Employee flexible spending accounts for health care represent one component of the current health care financing system that merits serious reform. These accounts create a system of undesirable incentives, force employees and employers to take complicated gambles, reduce tax revenues, and fail to meet their purported policy objectives. This paper describes shortcomings in these accounts from both a theoretical and an empirical perspective. Some proposed alternatives; including medical spending accounts and zero balance accounts, resolve many of these concerns but not all of them.

Use of a coded postcard to maintain anonymity in a highly sensitive mail survey: cost, response rates, and bias.
In a survey about euthanasia, 1,600 critical care nurses were randomly assigned to receive either three complete, anonymous mailings of the questionnaire or, with each mailing, a coded postcard to be returned separately from the questionnaire to reduce subsequent mailings to previous responders. The response rate in these two groups was 76.5% [95% confidence interval (CI) = 73.6-79.4%] and 69% (95% CI = 65.7-72.4%), respectively. The two strategies yielded similar responses, and costs were much lower for the postcard group. Using coded postcards to be returned separately from completed instruments appears to lower the response rate to anonymous mail surveys, but it also lowers cost and may not introduce additional bias.

Why some health policies don't make sense at the bedside.
Cost-effectiveness analysis and other forms of decision analysis are becoming more common in the medical literature and are increasingly influential in the development of health policy. Nevertheless, many clinicians find it difficult to apply policies developed from these analyses to individual encounters with patients. We examine the assumptions behind these analyses and argue that the perspective they embody can make clinical strategies appear to be less risky in theory than they are at the bedside. We believe that this problem underlies the intuitive concern many physicians have about policy analyses and calls into question the value of these analyses in shaping clinical practice. These analyses aggregate the benefits and burdens of alternative interventions across different individual persons. Thus, overall population risk appears blunted, as it would in a diversified portfolio of stocks that react differently to financial forces or in a herd of cattle that react differently to veterinary interventions. The assumptions behind these analyses make sense if aggregate outcome is what matters, but not if one cares about each individual investment or animal. Because such aggregation tends to understate individual risk, when applied to human health policy, it may misrepresent the interests of patients and cannot be assumed to provide useful guidelines for decision making at the bedside.

Medical specialists prefer to withdraw familiar technologies when discontinuing life support.
OBJECTIVE: To assess how members of different specialties vary in their decisions about which form of life support to withdraw. The hypothesis was that each specialty would be more comfortable withdrawing its "own" form of life support relative to other forms and other specialties. DESIGN: Mail survey. SETTING: 24 medical centers. PARTICIPANTS: 225 specialists in six specialties and 225 comparison physicians randomly matched according to percentage of time devoted to clinical practice. MEASUREMENTS: The six specialties were linked with six life-sustaining technologies related to their special expertise: 1) pulmonologists with mechanical ventilation, 2) nephrologists with hemodialysis, 3) gastroenterologists with tube feedings, 4) hematologists with blood products, 5) cardiologists with intravenous vasopressors, and 6) infectious disease specialists with antibiotics. The subjects ranked different forms of life support in the order in which they would prefer to withdraw them. They also expressed their preferences in response to hypothetical clinical vignettes. RESULTS: In five of the six specialties, the specialists had a relative preference for withdrawing their "own" form of life support, compared with the preferences of the comparison physicians. Overall, the physicians tended to prefer withdrawing a form of life support closely linked with their own specialty. CONCLUSIONS: Just as some specialist physicians tend to reach for different technologies first in treating patients, they also tend to reach for different technologies first when ceasing treatment. Specialists' preferences for different ways to withdraw life support not only may reflect a special understanding of the limits of certain technologies, but also may reveal how ingrained are physicians' patterns of practice.

Timing payments to subjects of mail surveys: cost-effectiveness and bias.
Although mailed surveys are an important component of epidemiological research, results from mailed surveys are often suspect because of poor response rates and the potential for nonresponse bias. Previous work has demonstrated that paying subjects to complete questionnaires increases response rates, but this work has not well addressed the impact of the timing of incentives on total cost, cost effectiveness, and response bias. We surveyed 400 university employees about health benefits. By random allocation, half received a check for $5 along with the mailed survey, and the other half received the promise of $5 on return of a completed survey. The response rates for both groups were about the same (64 and 59%, respectively), but prepayment was less expensive in aggregate and less expensive per response. In addition, we found that subjects with lower salaries were more likely to respond when paid in advance. We conclude that prepayment may actually be less expensive and more cost effective than payment on completion, but that the timing of payment may influence the profile of respondents.

Decisions to limit or continue life-sustaining treatment by critical care physicians in the United States: conflicts between physicians' practices and patients' wishes.
We surveyed a national sample of 879 physicians practicing in adult intensive care units in the United States, in order to determine their practices with regard to limiting life-sustaining medical treatment, and particularly their decisions to continue or forgo life support without the consent or against the wishes of patients or surrogates. Virtually all of the respondents (96%) have withheld and withdrawn life-sustaining medical treatment on the expectation of a patient's death, and most do so frequently in the course of a year. Many physicians continue life-sustaining treatment despite patient or surrogate wishes that it be discontinued (34%), and many unilaterally withhold (83%) or withdraw (82%) life-sustaining treatment that they judge to be futile. Some of these decisions are made without the knowledge or consent of patients or their surrogates, and some are made over their objections. We conclude that physicians do not reflexively accept requests by patients or surrogates to limit or continue life-sustaining treatment, but place these requests alongside a collection of other factors, including assessments of prognosis and perceptions of other ethical, legal, and policy guidelines. While debate continues about the ethical and legal foundations of medical futility, our results suggest that most critical care physicians are incorporating some concept of medical futility into decision making at the bedside.

Physician characteristics associated with decisions to withdraw life support.
OBJECTIVE: This study was undertaken to identify attributes of physicians associated with physicians' decisions to withdraw life support. METHODS: Of the 862 Pennsylvania internists surveyed and asked to make decisions in response to hypothetical vignettes and to report their actual experience with the withdrawal of life support, 485 (56%) responded. The data were analyzed with regression models. RESULTS: With other factors controlled, physicians were more willing to withdraw life support if they were young, practiced in a tertiary care setting, or spent more time in clinical practice; they were less willing if they were Catholic or Jewish. Physicians reported a higher frequency of actually withdrawing life support if they were young, had more contact with ICU patients, spent more time in clinical practice, or were specialists. Physicians with a greater willingness to withdraw were more likely to report having done so. CONCLUSIONS: Physicians' personal characteristics are associated with both their preferences and their practice in the withdrawal of life support, and a greater willingness to withdraw is associated with a higher frequency of withdrawal. The influence of physician characteristics demonstrates that patient preferences and clinical circumstances do not exclusively govern such ethical decisions.

Conflicts over post-exposure testing for human immunodeficiency virus: can negotiated settlements help?
Health care workers with needlestick exposures to patients' blood often request a test of the patient for evidence of infection with human immunodeficiency virus. If the patient refuses the test, a conflict develops between the interests of the health care worker and those of the patient. Traditional approaches to this dilemma attempt to balance the rights or utilities of abstract patients and health care workers. While these approaches have the advantage of offering clear guidelines in advance of conflict, the interests of the actual participants may differ from those used to create the guidelines. In nonmedical settings, conflicts are often resolved efficiently through negotiation and monetary exchanges. Although negotiated monetary settlements between health care workers and patients may be an impractical way to resolve medical conflicts, models developed from these perspectives provide insights into the individual interests of physicians and patients. Changing existing rules about medical record documentation, or increasing the penalties for the misuse of medical information, may satisfy the interests on both sides of the conflict and so represent integrative bargaining solutions. Even so, as the relationship between health care workers and their patients evolves, more explicit strategies for negotiation may become a reasonable solution to the problem of conflict.
