An integrative model of shared decision making in medical encounters

Background The questions patients are asked about their preferences with regard to life-sustaining treatment usually focus on specific interventions, but the outcomes of treatment and their likelihood affect patients' preferences. Methods We administered a questionnaire about treatment preferences to 226 persons who were 60 years of age or older and who had a limited life expectancy due to cancer, congestive heart failure, or chronic obstructive pulmonary disease. The study participants were asked whether they would want to receive a given treatment, first when the outcome was known with certainty and then with different likelihoods of an adverse outcome. The outcome without treatment was specified as death from the underlying disease. Results The burden of treatment (i.e., the length of the hospital stay, extent of testing, and invasiveness of interventions), the outcome, and the likelihood of the outcome all influenced treatment preferences. For a low-burden treatment with the restoration of current hea...

Understanding the Treatment Preferences of Seriously Ill Patients

The notion of medical futility has quantitative and qualitative roots that offer a practical approach to its definition and application. Applying these traditions to contemporary medical practice, we propose that when physicians conclude (either through personal experience, experiences shared with colleagues, or consideration of published empiric data) that in the last 100 cases a medical treatment has been useless, they should regard that treatment as futile. If a treatment merely preserves permanent unconsciousness or cannot end dependence on intensive medical care, the treatment should be considered futile. Unlike decision analysis, which defines the expected gain from a treatment by the joint product of probability of success and utility of outcome, our definition of futility treats probability and utility as independent thresholds. Futility should be distinguished from such concepts as theoretical impossibility, such expressions as "uncommon" or "rare," and emotional terms like "hopelessness." In judging futility, physicians must distinguish between an effect, which is limited to some part of the patient's body, and a benefit, which appreciably improves the person as a whole. Treatment that fails to provide the latter, whether or not it achieves the former, is "futile". Although exceptions and cautions should be borne in mind, we submit that physicians can judge a treatment to be futile and are entitled to withhold a procedure on this basis. In these cases, physicians should act in concert with other health care professionals, but need not obtain consent from patients or family members.

Medical Futility: Its Meaning and Ethical Implications

The traditional objective of advance care planning has been to have patients make treatment decisions in advance so that clinicians can attempt to provide care consistent with their goals. The authors contend that the objective for advance care planning ought to be the preparation of patients and surrogates to participate with clinicians in making the best possible in-the-moment medical decisions. They provide practical steps for clinicians to help patients and surrogate decision makers achieve this objective in the outpatient setting. Preparation for in-the-moment decision making shifts the focus from having patients make premature decisions based on incomplete information to preparing them and their surrogates for the types of decisions and conflicts they may encounter when they do have to make in-the-moment decisions. Advance directives, although important, are just one piece of information to be used at the time of decision making.

Redefining the Planning in Advance Care Planning: Preparing for End-of-Life Decision Making

Background Studies suggest that a majority of elderly patients would want to undergo cardiopulmonary resuscitation (CPR) if they had a cardiac arrest. Yet few studies have examined their preferences after clinicians have informed them about the outcomes of CPR. Methods To study older patients' preferences regarding CPR, we interviewed as many ambulatory patients as possible in one geriatrics practice in Denver from August 1, 1991, through July 31, 1992. Results A total of 371 patients at least 60 years of age were eligible; 287 completed the interview (mean age, 77 years; range, 60 to 99). When asked about their wishes if they had cardiac arrest during an acute illness, 41 percent opted for CPR before learning the probability of survival to discharge. After learning the probability of survival (10 to 17 percent), 22 percent opted for CPR. Only 6 percent of patients 86 years of age or older opted for CPR under these conditions. When asked about a chronic illness in which the life expectancy was less than o...

The influence of the probability of survival on patients' preferences regarding cardiopulmonary resuscitation.

Medical ethics education is instruction that endeavors to teach the examination of the role of values in the doctor's relationship with patients, colleagues, and society. It is one front of a broad curricular effort to develop physicians' values, social perspectives, and interpersonal skills for the practice of medicine. The authors define medical ethics education as more clinically centered than human values education and more inclusive of philosophical, social, and legal issues than is interpersonal skills training. The authors review the history of the emergence of medical ethics education over the last 20 years, examine the areas of consensus that have emerged concerning the general objectives and premises for designing medical ethics programs, and describe teaching objectives and methods, course content, and program evaluation used in such programs on both preclinical and clinical levels. The four interrelated requirements for successful institutionalization of medical ethics education programs are defined and discussed, and the paper ends with an overview of the uncertain future of medical ethics education, an accepted but still not fully mature part of physician training in the United States. An extensive reference list accompanies the article.

Objective: To assess the relationship between cardiopulmonary resuscitation (CPR) information and desire for CPR in an elderly population and to determine the influence of outcome data on desire for CPR in older persons.

Resuscitation decision making in the elderly: the value of outcome data.

Should do-not-resuscitate (DNR) orders be routinely rescinded when terminally ill patients undergo palliative surgery? If so, patients will be forced to balance the benefits of palliative surgery against the risks of unwanted resuscitation If physicians are required to honor intraoperative DNR orders, they may feel unacceptably restrained from correcting adverse effects for which they feel responsible This dilemma has been overlooked by DNR policies This article argues for the permissibility of honoring intraoperative DNR orders The patient's right to refuse treatment outweighs physicians' concerns about professional scrutiny over intraoperative deaths Physicians' moral concerns about hastening patient death are important but may be assuaged by (1) emphasizing patients' acceptance of operative mortality risk; (2) viewing matters as analogous to surgery on Jehovah's Witnesses who refuse lifesaving transfusion; (3) viewing the patient's intraoperative death as a double effect, that is, an unintended negative effect that is linked to the performance of a good act (palliation); and (4) distinguishing this from assisted suicide (JAMA 1991;266:2407-2412)

DNR in the OR. Resuscitation as an operative risk

Current methods used clinically to assess myocardial perfusion are invasive and expensive. As the technology of ultrasound imaging improves, CE may provide a relatively inexpensive, noninvasive means of quantitating myocardial perfusion. Issues regarding stability of microbubble contrast agents must be studied more closely under physiologic conditions. As such, encapsulated microbubbles may provide more stability under physiologic pressures than free gas microbubbles. Introducing high concentrations of contrast, either by hyperconcentrating the contrast agent or by increasing the injection rate, may provide greater stability under physiologic conditions. Further, before quantitative statement of tissue perfusion can be made, the relationship between tracer concentration and system response must be established. Further, a "linear" postprocessing ultrasound setting does not eliminate this requirement as data must still undergo nonlinear transformation during log compression and time-gain compensation. Additionally, issues regarding "electronic thresholding" must be explored more extensively in vivo. Commercial ultrasound scanners, in their present form, may not offer adequate sensitivity for absolute quantitative studies. Further development of modified ultrasound systems may provide sufficient sensitivity for quantitative perfusion imaging. CE offers a potentially powerful tool in the clinical management of patients with ischemic heart disease. Conventional coronary angiography provides information on the size of a lesion, but accompanying tissue perfusion distal to the lesion cannot be determined. Doppler ultrasonography determines velocity of blood flow in large vessels but does not offer the potential to quantitate tissue perfusion. Clearly, CE has a place in the future of diagnostic imaging. The recent work of Ito et al. demonstrated the qualitative potential of CE in the identification of "areas at risk" in patients who had undergone thrombolysis or percutaneous transluminal coronary angioplasty after an acute myocardial infarction. With further improvement in the ultrasound imaging techniques and microbubble stability, CE may offer an inexpensive, noninvasive means of assessing myocardial perfusion.
