African American patients' perspectives on medical decision making.

BACKGROUND: The medical literature offers little information about how older African Americans view the medical decision-making process. We sought to describe the perspectives of older African American patients in a primary care clinic as they consider a medical decision. METHODS: We interviewed 25 African American patients older than 50 years who had discussed flexible sigmoidoscopy with their primary care provider. Interviews were analyzed using qualitative methods. RESULTS: Patients listed concerns about cancer and health, risks and benefits, their own understanding of the test, and the recommendation of the provider as the most important factors in their decision. Most patients wanted information about medical tests and procedures to increase their understanding and to provide reassurance rather than to guide decision making. Most patients explained that they wanted the provider to make medical decisions because of his or her training and experience. Despite this, many expressed a sense of ownership or control over one's own body. Patients thought trust was built by a health care provider's honesty, patience, kindness, interest, and continuity of care. CONCLUSIONS: Although traditional models of informed consent have emphasized providing patients with information to guide autonomous decision making, patients may want this information for other reasons. Fully informing patients about their medical condition increases understanding and provides reassurance. Because many of these patients want their provider to participate in making medical decisions, he or she should not only provide information but should also provide guidance to the patient.

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.

The effects of vagus nerve stimulation on decision-making.

Subcortical and brainstem structures are increasingly becoming recognized as important contributors to higher cognitive functioning. Decision-making is one such function, particularly as viewed within the framework of the somatic marker hypothesis (SMH). The SMH views the participation in decision-making by the body proper as integral to emotional biasing and hence key to choosing in an advantageous manner. This study focuses on the vagus nerves as a possible conduit for somatic afferent signals pertinent to decision-making. We tested eight epileptic patients with implanted left vagus nerve stimulators. To assess decision-making we used the gambling task, which is sensitive to real-life decision-making deficits. Using a counterbalanced design, each participant performed the gambling task under a condition in which low-level vagus nerve stimulation (VNS) was covertly delivered, and another condition in which no VNS was delivered. Participants showed improved performance, that is, made more advantageous choices, in the stimulated relative to the unstimulated condition. Although these results should be viewed as preliminary, they suggest that the vagus nerve is a conduit for afferent somatic signals that can influence decision-making.

Developmental status, gender, age, and self-reported decision-making influences on students' risky and preventive health behaviors.

This study used decision-making theory to analyze the developmental changes associated with children's and adolescents' health behavior. High school and elementary school children completed surveys concerning (1) the extent to which they engage in a variety of preventive and risky health behaviors, and (2) influence sources used in decision making concerning the enactment of these behaviors. Multiple regression analysis revealed that the sources of influence children and adolescents report considering in making health-related decisions change developmentally and as a function of gender. Moreover, within and across age, children's sources of influence with respect to health decision making are dependent on the health domains being considered. The findings are discussed in relation to decision-making theory and the implications for the content and timing of health education initiatives for adolescents.

Communication and decision-making about seeking inherited cancer risk information: findings from female survivor-relative focus groups.

Dramatic advances in cancer genetics and identification of germline mutations in cancer genes such as BRCA1 and BRCA2 have led to new options in genetic risk assessment for families with histories of breast and ovarian cancer. However, little research has been carried out with individuals and their families regarding how cancer risk information is communicated within families and factors that may affect individuals and family members making informed decisions about their health. This study explored participants' knowledge of cancer risk, their perceptions and concerns regarding inherited cancer risk information, family communication patterns, and factors that may affect their decision to learn about inherited cancer risk in their families. Nine focus groups of family dyads were conducted (N=39) consisting of breast or ovarian cancer patients and close female relatives. All transcribed interviews were analyzed using qualitative software. Key findings showed diversity in how families communicated and made decisions about their health, persistent worry for their families, lack of knowledge about inherited cancer, vigilance in watching their health, and barriers present in communicating about genetic risk. Results from this study support inclusion of family members in addressing inherited cancer risk information and contextual family factors critical to consider in potentially high risk families.

Decision-making in young adolescents and adults.

In two experiments, 13-year-olds and college students were asked to make "risky" decisions in a game format. Analyses focused on whether adolescents and adults (a) used similar strategies for evaluating their options, (b) were equally optimistic, (c) held similar beliefs about their ability to produce outcomes, (d) were equally likely to choose the best options, and (e) had equally accurate memories of their performance. Results showed that age differences emerged along each of these dimensions, especially when the game was made more complex.

Decision-making in amnesia: do advantageous decisions require conscious knowledge of previous behavioural choices?

Previous work has reported that in the Iowa gambling task (IGT) advantageous decisions may be taken before the advantageous strategy is known [Bechara, A., Damasio, H., Tranel, D., & Damasio, A. R. (1997). Deciding advantageously before knowing the advantageous strategy. Science, 275, 1293-1295]. In order to test whether explicit memory is essential for the acquisition of a behavioural preference for advantageous choices, we measured behavioural performance and skin conductance responses (SCRs) in five patients with dense amnesia following damage to the basal forebrain and orbitofrontal cortex, six amnesic patients with damage to the medial temporal lobe or the diencephalon, and eight control subjects performing the IGT. Across 100 trials healthy participants acquired a preference for advantageous choices and generated large SCRs to high levels of punishment. In addition, their anticipatory SCRs to disadvantageous choices were larger than to advantageous choices. However, this dissociation occurred much later than the behavioural preference for advantageous alternatives. In contrast, though exhibiting discriminatory autonomic SCRs to different levels of punishment, 9 of 11 amnesic patients performed at chance and did not show differential anticipatory SCRs to advantageous and disadvantageous choices. Further, the magnitude of anticipatory SCRs did not correlate with behavioural performance. These results suggest that the acquisition of a behavioural preference--be it for advantageous or disadvantageous choices--depends on the memory of previous reinforcements encountered in the task, a capacity requiring intact explicit memory.

Evidence-based decision making: Guide to reading the dental materials literature.

Although potential links between materials data and clinical behavior are often implied, the status of such linkage is often left obscure. This paper provides clinicians a context within which to view materials information as evidence for clinical indications and to broaden readers' appreciation for the subject. Hierarchies of both clinical and nonclinical data are presented and discussed from the point of view of their predictive potential regarding clinical performance. Excellent sources of information are identified for the clinician making treatment decisions, and perspectives are offered on the value of other published materials data.

Drug abusers show impaired performance in a laboratory test of decision making.

A defining feature of drug addiction is persistent drug use despite long-term adverse consequences. This study examined the performance of drug abusers on a neuropsychological test that requires evaluation of long-term outcomes in the presence of a complex set of mixed reward/punishment contingencies (the Gambling Task). In order to control for generalized deficits related to choice and planning, subjects were also administered the Wisconsin Card Sorting Task. Thirty polysubstance abusers were compared to a comparison group of 24 subjects who did not use illicit drugs of abuse. Drug abusers performed much more poorly on the Gambling Task (net score = 10.2 +/- 4.7, mean +/- s.e.m.) than controls (26.0 +/- 5.3), but did not differ from controls on the Wisconsin Card Sorting Task. The results show that drug abusers are more likely to make maladaptive decisions in the Gambling Task that result in long-term losses exceeding short-term gains. These findings indicate that the Gambling Task may be a useful model in laboratory studies of cognitive dysfunctions associated with drug abuse.

Approaches to end-of-life decision-making in the NICU: insights from Dostoevsky's The Grand Inquisitor.

For many parents stopping life-sustaining medical treatment on their dying infant is psychologically impossible. Dostoevsky's insights into human behavior, particularly the fact that individuals do not want the anxiety and guilt associated with responsibility for making difficult decisions, might change the way physicians approach parents for permission to withdraw life-prolonging medical interventions on dying infants.

Facilitating informed decision making about breast cancer risk and genetic counseling among women calling the NCI's Cancer Information Service.

Despite increased interest among the public in breast cancer genetic risk and genetic testing, there are limited services to help women make informed decisions about genetic testing. This study, conducted with female callers (N = 279) to the National Cancer Institute's (NCI's) Atlantic Region Cancer Information Service (CIS), developed and evaluated a theory-based, educational intervention designed to increase callers' understanding of the following: (a) the kinds of information required to determine inherited risk; (b) their own personal family history of cancer; and (c) the benefits and limitations of genetic testing. Callers requesting information about breast/ovarian cancer risk, risk assessment services, and genetic testing were randomized to either: (1) standard care or (2) an educational intervention. Results show that the educational intervention reduced intention to obtain genetic testing among women at average risk and increased intention among high-risk women at 6 months. In addition, high monitors, who typically attend to and seek information, demonstrated greater increases in knowledge and perceived risk over the 6-month interval than low monitors, who typically are distracted from information. These findings suggest that theoretically designed interventions can be effective in helping women understand their cancer risk and appropriate risk assessment options and can be implemented successfully within a service program like the CIS.

Age and clinical decision making in oncology patients.

BACKGROUND: Ageism is a cultural bias that might inappropriately steer oncologists away from recommending aggressive treatments for older patients. The extent to which older patients might prefer less aggressive cancer therapies is unknown. Our lack of knowledge about patients' personal preferences for therapy may perpetuate this bias. PURPOSE: We conducted a study to determine 1) if age influences patient acceptance of cancer therapy and 2) if the older patients would be more or less likely to trade increased survival for maintaining quality of life than their younger counterparts. METHODS: Using an interview format, 244 cancer patients of all ages treated at a tertiary care cancer center read two sets of hypothetical vignettes. The first set consisted of four vignettes that varied in terms of stage of disease and treatment toxicity. Patients were asked to make hypothetical decisions about treatment given with respect to varying levels of either increasing cure or extending survival. The second set of vignettes presumed acceptance of cancer therapy. Within each vignette, two hypothetical treatments (mild versus severe) with different probabilities of 1-year survival were contrasted. The point at which patients shifted preferences from a treatment with mild versus severe side effects was the dependent measure. Mixed analysis of variance (ANOVA) procedures (F test) assessed the impact of age (< 65 years versus > or = 65 years) and patient disease stage (early versus advanced) on hypothetical decisions about treatment. All P values are two sided. RESULTS: In the treatment-preference vignettes, there was no effect of either age [F(1,239) = 2.14; P = .14] or patient stage [F(1,239) = .40; P = .53] on treatment acceptance. Older adults were as likely as their younger counterparts to agree to chemotherapy for both curative and control purposes. In the switch-point vignettes, younger adults switched to a more toxic treatment to gain survival advantage at an earlier point than the older patients in both the early-disease vignette [F(1,232) = 3.88; P = .05] and the advanced-disease vignette [F(1,232) = 4.43; P = .036]. There was neither an effect of disease stage on treatment decisions nor an interaction between disease stage and age. CONCLUSIONS AND IMPLICATIONS: In a tertiary care setting, older adults do not differ from their younger counterparts in terms of acceptance of chemotherapy. However, when treatment is presumed, they differ in terms of willingness to trade survival for current quality of life. Generalization of findings is limited by the relatively small sample of older adults (n = 43) and the referral population from which the sample was drawn. Replication with a larger older adult sample in a community setting is needed.

Data collection in decision-making: a study in general practice.

In a study of simulated consultations with patients suffering from dyspepsia, the amount and nature of information required by 20 general practitioners to make management decisions about these simulated patients were analysed. The number of items of information required to complete all eight cases ranged from 23 to 128 (median 66). Doctors who consulted more rapidly in actual surgeries required less information in the simulations (P less than 0.01). Two-way analysis of variance showed that both cases and doctors independently influenced the number of items of information collected, but that doctors were a more powerful influence (P less than 0.05). The nature of the information collected by doctors varied widely between individuals. There was no correlation between the professional experience of the doctors studied and the amount or nature of data collected; this is at odds with previous studies and requires an alternative explanation.

Making decisions for incapable adults 1: Capacity and best interest.

The Mental Capacity Act 2005 is expected to come into force in April 2007. It will change the way decisions are made for incapable adults in England and Wales. District nurses, along with other health professionals, will be required to abide by the provisions of the Act when providing care and treatment to incapable adults. In a short series of articles, case studies will be used to illustrate how the new law will affect district nurse practice, beginning with the assessment of capacity and best interests. District nurse Mary Holt regularly visits a patient, 78-year-old Jane Harris, in her home to treat a chronic leg ulcer. Jane has been diagnosed with Alzheimer's dementia but is managing well with support from the local authority. However, Mary has noticed recently that Jane's behaviour has become a little strange. She looks unkempt and she is continually washing dishes that are not dirty. On her last visit, Jane refused to allow Mary to remove the dressing on her leg and treat the ulcer, which has become infected. Mary is concerned that Jane's wound needs to be treated to prevent further complications.

Decision-making in state lotteries: half now or all of it later?

Many state lotteries offer players a choice between receiving roughly half of the jackpot immediately and receiving the entire jackpot over 25 annual payments. This requires players to make a decision that involves uncertainty, delay, and large amounts of real money. Archival data on lottery players' jackpot payment decisions were collected from seven state and three multistate lotteries. Players' jackpot payment preferences were assessed at the time of ticket purchase and after winning a jackpot. Preference for the annuity payment option significantly decreased as jackpot size increased, both at the time of ticket purchase and after winning. Furthermore, a significant proportion of winners who selected the annuity payment option at ticket purchase switched to the cash payment option after winning, whereas no winners switched from the cash to the annuity option after winning. These findings suggest that real-world choices involving large sums of money may be subject to diminishing marginal utility and probability and delay discounting.

The effects of accountability on bias in physician decision making: going from bad to worse.

Members of the Iowa Academy of Family Physicians participated in a survey study in which they were asked to make hypothetical decisions in either high- or low-conflict treatment conditions. In the low-conflict treatment condition the options were a common medication with a referral or a referral only. In the high-conflict treatment condition the same two options were given plus another attractive medication. In addition, we manipulated accountability by asking half of the participants to provide a written defense of their treatment options, which they would then agree to discuss at a later time. The results showed that physicians in the high-conflict condition chose the referral-only option significantly more than the physicians in the low-conflict condition, thus violating the normative rule of regularity. Moreover, that pattern was significantly amplified for physicians who were held accountable for their treatment decisions. These findings replicate and extend previous research and are discussed within the framework of reason-based choice.
