Contextual factors in clinical decision making: national survey of Canadian family physicians.

OBJECTIVE: Many factors are at play in the process of clinical decision making, but to date, the interaction of these factors has not been well understood. Such information could have important implications for teaching and promoting evidence-based medicine (EBM) in primary care. This study was designed to explore the relationship between physician-related variables and management of patient-related contextual factors in clinical decision making. A secondary objective was to examine the extent to which this relationship varies by type of clinical decision. DESIGN: Cross-sectional randomized postal survey of 1134 Canadian primary care physicians stratified by age, sex, and practice location. Nonrespondents were sent reminders at 4 weeks and again at 8 weeks; at 12 weeks, all remaining nonrespondents were mailed replacement copies of the questionnaire. SETTING: Family practices in Canada. PARTICIPANTS: Of the final sample of 431 family physicians, 52% were men, 63% practised in urban locations, and 71% were in group practice. MAIN OUTCOME MEASURES: Self-reported likelihood of considering various contextual factors during the course of clinical decision making. RESULTS: Despite the three follow-up mailings, the final response rate was 42%; however, nonrespondents did not differ significantly from respondents on three important demographic factors: age, sex, and practice location. Using multinomial logistic regression analysis, the data showed that female family physicians and practitioners less strongly identified with EBM were more likely to consider contextual factors in clinical decision making. The effect was more obvious for ordering tests than for decisions about treatment. CONCLUSION: The evolving model of EBM should consider important physician-related variables in clinical decision making. Our data indicate that physicians' sex and identification with the tenets of EBM influence management of contextual factors. These results have important implications because they indicate that clinicians strongly identified with the EBM model of clinical practice are less sensitive to context, which might be an obstacle to efforts to integrate patient values and clinical circumstances into patient-centred care. We believe these findings support continued development of the model of "context-sensitive medicine" previously proposed as an alternative to EBM.

Impact of patient acuity on preference for information and autonomy in decision making.

OBJECTIVES: To test the hypotheses that ED patients' desires for medical information and for autonomy in decision making are inversely related to increasing acuity of illness, increasing age, and lower level of formal education. METHODS: The authors conducted a prospective study of ED patients who presented for care during seven nonconsecutive 24-hour periods. Of 804 patients approached, 665 completed a questionnaire that was administered by a trained research assistant. Patients rated their desire for medical information, and for participation in medical decision making, on two 10-cm visual analog scales. Patient acuity level was determined in routine fashion by trained triage nurses, who were unaware of the nature of this study. RESULTS: Desire for information was uniformly high, and did not vary statistically between triage groups (p = 0.41). The most acutely ill patients (level I) were more likely to be excluded by the research interviewer (p < 0.001). Of included level I patients, desire to participate was not decreased (p < 0.01). Higher level of formal education (p = 0.036) and younger age (p < 0.001) were associated with greater desire for autonomy in decision making. CONCLUSION: Among ED patients able to participate, higher acuity of illness was not associated with a decreased desire for medical information. Many very acutely ill patients preferred autonomy in medical decision making. Older patients and those with less formal education expressed a lesser desire for decision-making autonomy.

Decision-making in the diagnosis and treatment of leukemia.

OBJECTIVES: To review the precepts of decision-making for people diagnosed with leukemia. DATA SOURCES: Professional journals, research studies, review articles, and personal experience. CONCLUSION: Decision-making is one of the most complex and demanding tasks faced by people diagnosed with leukemia. There are multiple dimensions of decision-making, including access to information, psychosocial support, spiritual support, education options for treatment and participation in clinical trials. IMPLICATIONS FOR NURSING PRACTICE: Health care professionals are integral to the decision-making process for people diagnosed with leukemia and are involved in most situations where decisions must be made relative to treatment, research, and symptom management.

Applying the decision-making model: case study 1.

The options for decision making in this situation are reviewed in step 8. As you select one of these options or add one not listed, ask yourself the following questions: Why did I select that particular option? Is this option I selected consonant with my own personal and professional values? If not, where are the conflicts? Have I considered all the evidence in a logical sequence, or did I jump to my conclusion when I first read through the case? Have I had experience caring for a mother and infant in a similar situation? If so, to what extent did my previous experience influence my choice of action in this situation? Can I implement the decision? If not, why? This series of questions can assist the nurse or other health professional in actually making a decision and thinking about their personal reaction to implementing it (accountability). Critical thinking and taking time to analyze one's decision-making process are important tools that help each of us make morally appropriate decisions in clinical practice. The results are better patient care and the personal satisfaction of knowing you have done your best to promote the best interests of infants assigned to your care.

Client-caregiver-nurse coalition formation in decision-making situations during home visits.

AIMS: The purpose of this paper is to report the findings of an exploratory study designed to test a portion of the Theory of Collaborative Decision-Making in Nursing Practice for Triads by examining the relation between types of decisions and formation of coalitions during triadic interactions among older home healthcare clients, their caregivers and home healthcare nurses during seven admission visits for home health care. BACKGROUND: Although home healthcare nurses include clients and family members in decision-making about care, few publications address the nature of interactions among triads of clients, caregivers and nurses in home health care and the association between decision-making and those interactions. METHOD: The data presented in this paper are a secondary analysis of data originally collected in 1994. The sample included 157 decision-making situations identified from interactions of seven triads of older home healthcare clients, their caregivers and nurses. Qualitative data were collected by participant observation and audio-recording of admission visit interactions among clients, caregivers and nurses. Content analysis, augmented by Ethnograph software, was used to analyse the data. FINDINGS: Coalitions were evident in just eight of the 157 decision-making situations. All of the theoretically possible types of nursing care decisions (programme, operational control, agenda) were observed. Each coalition involved one nursing care decision; two coalitions formed in one triad. Seven coalitions formed between nurse and caregiver against client during two programme and five operational control decisions. One coalition formed between client and caregiver against nurse during an agenda decision. No coalitions formed between client and nurse against caregiver. CONCLUSIONS: Although the study sample was small, the findings expand understanding of the relation between types of decisions and formation of coalitions during triadic interactions in home health care, and provided empirical support for a portion of the Theory of Collaborative Decision-Making in Nursing Practice for Triads.

Impaired decision making following 49 h of sleep deprivation.

Sleep deprivation reduces regional cerebral metabolism within the prefrontal cortex, the brain region most responsible for higher-order cognitive processes, including judgment and decision making. Accordingly, we hypothesized that two nights of sleep loss would impair decision making quality and lead to increased risk-taking behavior on the Iowa Gambling Task (IGT), which mimics real-world decision making under conditions of uncertainty. Thirty-four healthy participants completed the IGT at rested baseline and again following 49.5 h of sleep deprivation. At baseline, volunteers performed in a manner similar to that seen in most samples of healthy normal individuals, rapidly learning to avoid high-risk decks and selecting more frequently from advantageous low-risk decks as the game progressed. After sleep loss, however, volunteers showed a strikingly different pattern of performance. Relative to rested baseline, sleep-deprived individuals tended to choose more frequently from risky decks as the game progressed, a pattern similar to, though less severe than, previously published reports of patients with lesions to the ventromedial prefrontal cortex. Although risky decision making was not related to participant age when tested at rested baseline, age was negatively correlated with advantageous decision making on the IGT, when tested following sleep deprivation (i.e. older subjects made more risky choices). These findings suggest that cognitive functions known to be mediated by the ventromedial prefrontal cortex, including decision making under conditions of uncertainty, may be particularly vulnerable to sleep loss and that this vulnerability may become more pronounced with increased age.

Treatment decision-making and the form of risk communication: results of a factorial survey.

BACKGROUND: Prospective users of preventive therapies often must evaluate complex information about therapeutic risks and benefits. The purpose of this study was to evaluate the effect of relative and absolute risk information on patient decision-making in scenarios typical of health information for patients. METHODS: Factorial experiments within a telephone survey of the Michigan adult, non-institutionalized, English-speaking population. Average interview lasted 23 minutes. Subjects and sample design: 952 randomly selected adults within a random-digit dial sample of Michigan households. Completion rate was 54.3%. RESULTS: When presented hypothetical information regarding additional risks of breast cancer from a medication to prevent a bone disease, respondents reduced their willingness to recommend a female friend take the medication compared to the baseline rate (66.8% = yes). The decrease was significantly greater with relative risk information. Additional benefit information regarding preventing heart disease from the medication increased willingness to recommend the medication to a female friend relative to the baseline scenario, but did not differ between absolute and relative risk formats. When information about both increased risk of breast cancer and reduced risk of heart disease were provided, typical respondents appeared to make rational decisions consistent with Expected Utility Theory, but the information presentation format affected choices. Those 11% - 33% making decisions contrary to the medical indications were more likely to be Hispanic, older, more educated, smokers, and to have children in the home. CONCLUSIONS: In scenarios typical of health risk information, relative risk information led respondents to make non-normative decisions that were "corrected" when the frame used absolute risk information. This population sample made generally rational decisions when presented with absolute risk information, even in the context of a telephone interview requiring remembering rates given. The lack of effect of gender and race suggests that a standard strategy of presenting absolute risk information may improve patient decision-making.

The development of COMRADE--a patient-based outcome measure to evaluate the effectiveness of risk communication and treatment decision making in consultations.

Some instruments have been developed to evaluate 'decision effectiveness' such as the 'satisfaction with decision (SWD)' and 'decision conflict (DCS)' scales and are validated for the US context. Patients identify further outcome domains that are not fully covered in these scales. We developed a patient-based outcome measure to evaluate risk communication and decision making effectiveness, addressing these further domains and validated for use in the UK. Formulation of items was based on literature review and key informant interviews. The instrument was piloted and developed (including psychometric assessment) in the context of a trial of decision making and risk communication interventions in general practice. Patients were recruited to the trial with known atrial fibrillation, prostatism, menorrhagia or menopausal symptoms. High response rates (96% in first phase) indicated acceptability to patients. A 20 item patient-based outcome measure, with two sub-scales for 'risk communication' and 'confidence in decision', was produced. It allows for paternalistic, shared or informed choice decision making models. Usage in further studies will facilitate systematic reviews. Consequently, lessons for wider application of these interventions in practice, and policy implications regarding greater patient involvement should then be clearer.

How is medical decision-making shared? The case of haemophilia patients and doctors: the aftermath of the infected blood affair in France.

OBJECTIVE: This article looks at how users and doctors in France have rethought the question of shared decision-making in the clinical field of haemophilia following a major crisis - that of the infected blood affair. DESIGN: We did a qualitative survey based on semi-structured interviews in three regions of France. SETTING AND PARTICIPANTS: The interviews covered 31 clinical doctors of haemophilia and 31 users: 21 adult males with severe haemophilia (21/31), infected (14/21) or not (7/21) with HIV, the infected wife of one of the latter (1/31) and nine parents of young patients with severe haemophilia (9/31), either HIV positive (6/9) or negative (3/9). RESULTS AND CONCLUSIONS: The results show the infected blood affair to be a major individual and collective ordeal. It has caused users and doctors to rethink their roles within clinical relationships and to develop new ways of sharing medical decision-making. Prior to the crisis, the dominant model was based upon a distinction between the medical aspect, governed by the doctors, and the psychosocial aspect, which involved the patients and their families. Since the crisis, medicoscientific knowledge has been shared between users and doctors. This general trend nevertheless permits the existence of different patient, family and doctor profiles which in turn correspond to different notions of what a clinical decision should be. Some users remain attached to the idea of complementarity between doctors and patients (new partnership model), whilst others put doctors and patients on an equal footing (negotiation model). On the doctors' side, whilst some still prefer the initial model for therapeutic decision-making, the majority have reassessed their perceptions and viewpoints. A certain number believe that decisions should be made by both doctor and patient in accordance with scientific procedures (decision-making controlled by scientific standards) or regulatory procedures (decision-making controlled by legal standards). Yet others feel that multiple points of view are acceptable within the decision-making process (decision-making model as interactivity).

Assessing patients' participation and quality of decision-making: insights from a study of routine practice in diverse settings.

In the context of a qualitative study exploring patients' participation in decision-making, we investigated how people interpret and respond to structured questions about decision-making about their health care. Seventy-four participants who attended consultations in five clinical areas completed structured measures of decision-making and discussed their responses during interviews. They identified a range of decisions as having being made in their consultations. People who picked particular responses on measures of participation in and satisfaction with decision-making gave varied explanations for these, not all of which were consistent with the way their responses are usually interpreted. The interview data suggest that people's evaluations of decisions to follow a particular course of action were influenced by various factors including what they focused on as the alternative, their perceptions of constraints on choices, and their assessment of how good the best possible solution was. Responses to simple structured measures of participation in and satisfaction with decision-making should be interpreted with caution. They are not reliably attributable to health care providers' actions and are thus unsuitable for performance assessment purposes.

A novel computer based expert decision making model for prostate cancer disease management.

PURPOSE: We propose a strategic, computer based, prostate cancer decision making model based on the analytic hierarchy process. We developed a model that improves physician-patient joint decision making and enhances the treatment selection process by making this critical decision rational and evidence based. MATERIALS AND METHODS: Two groups (patient and physician-expert) completed a clinical study comparing an initial disease management choice with the highest ranked option generated by the computer model. Participants made pairwise comparisons to derive priorities for the objectives and subobjectives related to the disease management decision. The weighted comparisons were then applied to treatment options to yield prioritized rank lists that reflect the likelihood that a given alternative will achieve the participant treatment goal. Aggregate data were evaluated by inconsistency ratio analysis and sensitivity analysis, which assessed the influence of individual objectives and subobjectives on the final rank list of treatment options. RESULTS: Inconsistency ratios less than 0.05 were reliably generated, indicating that judgments made within the model were mathematically rational. The aggregate prioritized list of treatment options was tabulated for the patient and physician groups with similar outcomes for the 2 groups. Analysis of the major defining objectives in the treatment selection decision demonstrated the same rank order for the patient and physician groups with cure, survival and quality of life being more important than controlling cancer, preventing major complications of treatment, preventing blood transfusion complications and limiting treatment cost. Analysis of subobjectives, including quality of life and sexual dysfunction, produced similar priority rankings for the patient and physician groups. Concordance between initial treatment choice and the highest weighted model option differed between the groups with the patient group having 59% concordance and the physician group having only 42% concordance. CONCLUSIONS: This study successfully validated the usefulness of a computer based prostate cancer management decision making model to produce individualized, rational, clinically appropriate disease management decisions without physician bias.

Nurses decision-making in clinical practice.

AIM: To identify what decisions nurses make in medical, surgical and critical care areas and compare the results. METHOD: A clinical decision-making questionnaire (CDMQ) consisting of 15 statements was developed. A total of 60 nurses completed the questionnaire: 20 from each of three clinical areas. RESULTS: Most nurses, in all specialties, regularly made clinical decisions on direct patient care, which included providing basic nursing care and psychological support, and teaching patients and/or family members. Although nurses in all specialties regularly managed the work environment, they did not make decisions on the ward or unit budget, supervise junior staff or mentor student nurses. Critical care nurses regularly made decisions on their extended roles, such as acting in emergency situations and deciding to change patient medication, while medical and surgical nurses only did this occasionally. Length of clinical experience is significantly related to the frequency of decision-making. CONCLUSION: The decisions nurses make are directly related to the clinical areas in which they work. However, it would be interesting to know if nurses showed particular aptitudes for different types and levels of decision-making and if this is related to other factors such as personality, education and experience in nursing.

Decision making and satisfaction with care in the pediatric intensive care unit: findings from a controlled clinical trial.

OBJECTIVE: To facilitate critical decision making and improve satisfaction with care among families of patients in a pediatric intensive care unit. DESIGN: Prospective observational study followed by a nonrandomized controlled trial of a clinical intervention to identify conflicts and facilitate communication between families and the clinical team. SETTING: The pediatric intensive care unit of a Boston teaching hospital. PATIENTS: A total of 127 patients receiving care in the pediatric intensive care unit in 1998-1999 and their families. INTERVENTIONS: Interviews were conducted with surrogates and decisionally capable older children concerning the adequacy of information provided, understanding, communication, and perceived decisional conflicts. Findings were relayed to the clinical team, who then developed tailored follow-up recommendations. MEASUREMENTS AND MAIN RESULTS: A survey administered to surrogates at baseline and day 7 or intensive care unit discharge measured satisfaction with care. Information on patient acuity and hospital stay were extracted from medical records and hospital databases. Wilcoxon rank-sum tests and incidence rate comparisons were used to assess the impact of the intervention on satisfaction and sentinel decision making, respectively. Incidence rates of care plan decision making, including decisions to adopt a comfort-care-only plan and decisions to forego resuscitation, were lower among families who received the intervention. The intervention did not significantly affect satisfaction with care. CONCLUSIONS: Prospectively screening for and intervening to mitigate potential conflict did not increase decision making or parental satisfaction with the care provided in this pediatric intensive care unit.

Gambling with your life: the process of breast cancer treatment decision making in Chinese women.

Treatment decision making (TDM) studies have primarily focused on assessing TDM quality and predominantly presume rational analytic processes as the gold standard. In a grounded theory study of 22 Hong Kong Chinese women following breast surgery who completed an in-depth interview exploring the process of TDM in breast cancer (BC), narrative data showed that discovery of a breast abnormality and emotional responses to BC diagnosis influence the TDM process. Lack of guidance from surgeons impaired TDM. Decisions were, for the most part, made using intuitive, pragmatic and emotionally driven criteria in the absence of complete information. The experience of TDM, which was likened to gambling, did not end once the decision was made but unfolded while waiting for surgery and the post-operative report. In this waiting period, women were emotionally overwhelmed by fear of death and the uncertainty of the surgical outcome, and equivocated over whether they had made the 'right' choice. This suggests that Chinese women feel they are gambling with their lives during TDM. These women are particularly emotionally vulnerable whilst waiting for their surgery and the post-surgical clinical pathology results. Providing emotional support is particularly important at this time when these women are overwhelmed by uncertainty.

A neurocognitive model of the ethical decision-making process: implications for study and practice.

The field of business ethics is entrenched in a cognitive approach that portrays the ethical decision-making process as a completely deliberate and reasoned exercise. In light of growing concerns about the veracity of this approach, I build upon current knowledge of how the brain functions to present a neurocognitive model of ethical decision making. The model suggests that ethical decision making involves 2 interrelated yet functionally distinct cycles, a reflexive pattern matching cycle and a higher order conscious reasoning cycle, and thereby describes not only reasoned analysis, but also the intuitive and retrospective aspects of ethical decision making. The model sparks research in new areas, holds significant implications for the study of ethical decision making, and provides suggestions for improving ethical behavior in organizations.

The effects of low doses of delta-9 tetrahydrocannabinol on reinforcement processing in the risky decision-making of young healthy adults.

Research suggests that risky decision-making is sensitive to neuromodulatory influences acting upon corticolimbic circuitry. However, while other evidence attests to effects of delta-9 tetrahydrocannabinol (THC) on the activity of reward pathways, relatively little is known about the possible involvement of cannabinoid activity in risky choice. In this experiment, we examined the effects of a single sublingual 5 mg dose of THC on a test of risky decision-making (requiring choices between simultaneously presented gambles differing in their magnitude of gains, magnitude of losses and the probability with which these outcomes were delivered). Tests of non-normative decision-making involving risk-aversion when deciding between gains and risk-seeking choices when deciding between losses were also included. In all, 15 healthy adults were administered 5 mg THC and placebo in a double-blind, placebo-controlled, within-subject, cross-over design. THC had three principal effects relative to placebo: (i) THC reduced choice of gambles with variable gains and losses, but increased choice of gambles with zero-expected value; (ii) THC reduced participants' attention towards losses when the probability of winning was low (and the probability of losing was high); and (iii) THC speeded participants' responses to gambles with large compared to small potential gains. These results suggest that THC mediates specific motivational processes and the processing of reinforcement cues during risky choice, perhaps reflecting altered CB1 receptor or catecholamine activity within corticolimbic pathways.

Psychiatric hospitalization decision making by CMHC staff.

The decision to recommend hospitalization for patients with psychiatric illness is often made on the basis of unknown reliability and validity. The purpose of this study was to examine the characteristics and reliability of self-reported psychiatric hospitalization decision making among staff at a Community Mental Health Center. Foremost among the results, the conditions that staff consider to be appropriate indicators of hospitalization show only modest reliability. Kappa interrater reliabilities of .10 to .60 persist across different staff types and different patient problems. Results from hypothetical cases support a micro-certainty, macro-uncertainty hypothesis: staff are highly confident in the appropriateness of their treatment recommendations, but the recommendations across staff are variable. The results empirically demonstrate the need to improve the reliability of the hospitalization decision, and to work towards valid outcomes-based hospitalization criteria.
