The impact of patient participation on adherence and clinical outcome in primary care of depression.

OBJECTIVE: Patient participation in shared treatment decision-making is hypothesized to improve depression treatment adherence and clinical outcomes in depressed patients. The study aim was to evaluate the impact of patient participation on these factors and to determine the variance of clinical outcome as the primary outcome variable. METHODS: A survey was administered to 30 general practitioners and 207 depressed patients, at initial consultation and 6-8 weeks later. General practitioners documented their clinical practice and patients completed questionnaires including Brief-PHQ for depression and clinical outcome, patient participation scale, and visual analogue scales for treatment adherence. Assessment of correlations was followed by the development of a structural equation model (as a latent variable analysis) to define a model to explain the entire set of the variables' relationships. RESULTS: Sixty percent of the variance in clinical outcome was attributable to patient adherence (beta=0.41) and baseline depression severity (beta=0.65). Depression severity predicted clinical outcome but not patient participation. Participation predicted adherence (beta=0.39) but did not directly affect clinical outcome. Adherence was explainable by physician- (beta=0.57) and patient-reported treatment adherence (beta=0.66). CONCLUSION: In a specific pathway via adherence, patient participation in decision-making influences clinical outcome in primary care of depression. PRACTICE IMPLICATIONS: The research findings reveal the significance of patient participation as a key factor to address for improving treatment adherence and clinical outcome. Quality improvement strategies for depression treatment should emphasize patient participation.

Treatment preference patterns during a videotape decision aid for benign prostatic hyperplasia (BPH).

OBJECTIVE: As part of a study of men's responses to a videotape decision aid [Rovner DR, Wills CE, Bonham V, Williams G, Lillie J, Kelly-Blake K, Williams MV, Holmes-Rovner M. Decision aids for benign prostatic hyperplasia: applicability across race and education. Med Decis Making 2004;24:359-66], preferences for BPH treatment options were assessed. METHODS: One hundred and sixty men stratified by race and education completed a semi-structured interview that included assessments of treatment preferences. RESULTS: Most men initially and ultimately favored watchful waiting over other options, and 56.6% never changed their preference rank orders while viewing the videotape. BPH severity in context of treatment risk avoidance, efficacy, and expert opinion factors were frequently cited reasons for preference orders. Lesser education was associated with higher likelihood of changing preferences (r = -.30, p < .001), and percent increase in BPH knowledge pre- to post-videotape was weakly associated with fewer non-dominant preference shifts (r = -.19, p < .05). CONCLUSION: Conservatism regarding BPH treatment is moderated by context-specific factors, including new information. PRACTICE IMPLICATION: Counseling in a provider-patient partnership model should address both sources of variance in men's treatment preferences.

Integrating Decision Making and Mental Health Interventions Research: Research Directions.

The importance of incorporating patient and provider decision-making processes is in the forefront of the National Institute of Mental Health (NIMH) agenda for improving mental health interventions and services. Key concepts in patient decision making are highlighted within a simplified model of patient decision making that links patient-level/"micro" variables to services-level/"macro" variables via the decision-making process that is a target for interventions. The prospective agenda for incorporating decision-making concepts in mental health research includes (a) improved measures for characterizing decision-making processes that are matched to study populations, complexity, and types of decision making; (b) testing decision aids in effectiveness research for diverse populations and clinical settings; and (c) improving the understanding and incorporation of preference concepts in enhanced intervention designs.

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.

Patient comprehension of information for shared treatment decision making: state of the art and future directions.

How does the way that information is presented potentially influence patients' consent for health treatments, in a shared decision making process? The goal of this paper is to present an overview of selected recent literature concerning patient health information presentation/use for treatment decision making. Recent work with patient populations has begun to extend early cognitive psychological work showing systematic biases in thinking. Key research findings are organized by type of format (probability, graphic, and qualitative/quantitative dimensions). The applied literature on this topic is amenable to only limited integration in regard to key findings, and relatively few novel approaches to improving information comprehension have been described in the health literature. Promising approaches being proposed, developed, and tested are described, such as enhanced-access computerized patient choice modules, "debiasing" techniques, and tailoring of information. Additional theoretical and practical issues are discussed, as well as selected policy implications of current knowledge.

Preliminary validation of the Satisfaction With Decision scale with depressed primary care patients.

OBJECTIVE: To conduct a preliminary validation of the Satisfaction With Decision (SWD) scale with depressed primary care patients. DESIGN: Cross-sectional observational pilot study using a postal survey. SETTING AND PARTICIPANTS: Depressed primary care patients (n = 97) who recently had made a new decision about antidepressant medication use completed surveys regarding their treatment decisions. MAIN VARIABLES: Measures included patient-reported satisfaction with decision, decisional conflict, knowledge about depression and treatment, decision involvement, pain and health status, antidepressant medication efficacy, and satisfaction with health services. RESULTS: The SWD scale had good internal consistency reliability (alpha = 0.85). Evidence for construct validity was confirmed via a hypothesized pattern of relationships between the SWD scale and other measures. Decision satisfaction was associated with several issues of relevance for designing patient-centred decision support interventions: (1) knowledge about depression and treatment; (2) involvement in health-related decisions; and (3) aiding evaluation of trade-offs among pros and cons of treatment. CONCLUSIONS: The results of this pilot study show that the SWD scale appears to be a psychometrically sound and practical measure for research with this population. Additional research is needed on the theoretical nature of decision satisfaction and developing and testing patient-centred decision support interventions for depression treatment.

Improving informed consent: insights from behavioral decision research.

BACKGROUND: With publication of The Belmont Report concerning ethical principles, informed consent gained explicit guidelines for the protection of human subjects of research. However, there is still little evidence about how well informed consent works to assist patients to reach informed decisions about research participation. OBJECTIVE: To review behavioral decision theory and research to identify implications for informed consent. RESEARCH DESIGN: Traditional literature review and hand search of literature were used. RESULTS: Psychological research on biases and heuristics identifies cognitive biases in information processing (selection and interpretation of risks and benefits) that have implications for improving the informing process. A growing literature on patient decision aids provides evidence for the feasibility of more fully informing patients, and includes examples of "debiasing" procedures (to improve information comprehension and consent). CONCLUSIONS: Informing and consenting involve conceptually different challenges concerning effectiveness versus values. Debiasing techniques need to be developed and empirically tested to determine their effectiveness in informing patients. Consenting involves both social and individual values. Appealing to altruism when summarizing the goals of research may increase research participation and does not necessarily violate voluntariness of informed consent. Additional research is needed to determine when information-processing biases occur problematically in health-related informed consent, and whether appealing to altruism increases research participation.

Graduate nursing students' precourse and postcourse perceptions and preferences concerning completely web-based courses.

Web-based nursing courses have proliferated rapidly in recent years, but few data are available about course outcomes. A pretest/posttest survey design of student perceptions and preferences was used to evaluate two graduate-level on-line nursing courses (required research and elective aging issues courses; N = 31 and N = 29, respectively) on the basis of Billings' outcomes evaluation framework for nursing Web-based courses. Students in both courses were favorable or at least neutral in their perceptions of outcomes at both pretest and posttest, but favorable shifts in perceptions also occurred from pretest to posttest. Most students remained stable in their preferences for format of instruction (on-line or classroom), and most favored an on-line format. Almost all students indicated they would take the course they took if they had the decision to make over again. Students who took the elective aging issues course had somewhat more favorable perceptions overall at posttest, compared to the required research course, but some differences were accounted for by pretest score differences between the groups. While outcomes were positive for both courses, the results also highlight specific needs for adequate socialization and support of students, particularly for first-year graduate students who are taking Web-based courses.

Navigating the course of scholarly productivity: the protégé's role in mentoring.

BACKGROUND: The importance of mentoring for professional success, including mentoring in writing, has become increasingly emphasized in academic nursing during the past decade. Although much has been published on how to write for publication, as well as the roles of mentors themselves, surprisingly little has been written about how protégés (those who are the recipients of mentoring) can take an active role in assisting themselves to obtain mentorship. How newer faculty can obtain adequate mentoring is often less straightforward. PURPOSE: The main goal of this article is to describe some ideas about how faculty can actively help themselves to obtain adequate mentoring, with a particular focus on mentoring in writing. METHOD/DISCUSSION: Five principles are illustrated as follows, with case examples of hypothetical new faculty members: know yourself, develop realistic expectations, reach out and get to know others, negotiate for what is needed, and learn from every experience. CONCLUSION: We hope that this discussion will foster further exchange among mentors, protégés, and administrators about approaches to seeking mentoring and high-level success in writing for publication along career journeys.

Decision aids for benign prostatic hyperplasia: applicability across race and education.

BACKGROUND/METHOD: Decision aids have not been widely tested in diverse audiences. The authors conducted interviews in a 2 x 2 race by education design with participants who were 50 years old (n = 188). The decision aid was a benign prostatic hyperplasia videotape. RESULTS: There was an increase in knowledge equal in all groups, with baseline knowledge higher in whites. The decision stage increased in all groups and was equivalent in the marginal-illiterate subgroup (n = 0.15). CONCLUSION: Contrary to expectations, results show no difference by race or college education in knowledge gain or increase in reported readiness to decide. The video appeared to produce change across race and education. The end decision stage was high, especially in less educated men. Results suggest that decision aids may be effective without tailoring, as suggested previously to enhance health communication in diverse audiences. Research should test findings in representative samples and in clinical encounters and identify types of knowledge absorbed from decision aids and whether the shift to decision reflects data/knowledge or shared decision-making message.
