Decision-making role preferences and information needs: a comparison of colorectal and breast cancer

Objective: An exploratory study has been carried out to examine decision-making role preferences and information needs for a sample of people with colorectal cancer (n = 48). The work replicated a larger study carried out for women with breast cancer (n = 150), and this paper compares and contrasts findings for both disease groups. Design: A cross-sectional design was employed, involving structured interviews. The main variables investigated were decision-making preference (using a decisional role preference card sort), perceived decisional role and information need (using an information needs questionnaire). Results: The majority (78%) of the colorectal cancer patients preferred to play a passive role in decision making, in contrast to 52% of women with breast cancer in previous work. Eighty per cent of the colorectal sample and 61% of the women with breast cancer perceived that the doctor had made treatment decisions. Priority information needs for both groups related to cure, spread of disease and treatment options. Conclusions: The two most striking findings from the comparison between the two disease groups relate to the differences in decision-making role preferences and the similarities in information needs. The process of involving people with colorectal cancer in treatment decision making warrants further investigation. The similarity in information needs of the two disease groups has implications for health care professionals providing information to people with cancer

Preferências pelas decisões compartilhadas em pacientes com depressão

Neste estudo, analisaram-se os processos psicológicos associados com as preferências dos pacientes com depressão na tomada de decisão sobre seu tratamento psiquiátrico. Participaram 462 pacientes diagnosticados com um transtorno depressivo agudo ou recorrente. A maior parte preferiu assumir um papel colaborativo-passivo ou totalmente passivo. Os resultados não mostraram diferenças significativas entre pacientes em função de sua cronicidade na preferência por tomada de decisões, embora um maior tempo de tratamento tenha sido associado com um estilo mais passivo. O MANCOVA aplicado ao total de participantes, controlando a idade, o nível educativo e o tempo de tratamento, indicou que os pacientes colaborativos e passivos mostraram maior lócus de controle centralizado na confiança no psiquiatra do que os ativos. Constataram-se diferenças de gênero que mostraram nos homens maior lócus de controle interno e reatância psicológica, e, nas mulheres, maior lócus centralizado no aleatório, o lócus centralizado no psiquiatra e uma percepção de menor autoeficácia. Os achados indicam a necessidade de estudar, sob uma perspectiva diferencial, a participação dos pacientes na tomada de decisão de acordo com os processos psicológicos e a repercussão que esta tem na aderência ao tratamento médico.En el presente estudio se analizaron los procesos psicológicos asociados con las preferencias de los pacientes con depresión en la toma de decisión sobre su tratamiento psiquiátrico.

Se encontraron diferencias de género mostrando en los hombres mayor locus de control interno y reactancia psicológica, y en las mujeres, mayor locus centrado en el azar. Los análisis de regresión indicaron que en el caso de los hombres, la preferencia pasiva por la toma de decisión es explicada por el locus centrado en el psiquiatra. Sin embargo, en las mujeres tuvo mayor peso la edad, seguida del locus centrado en el azar, el locus centrado en el psiquiatra y una percepción de menor autoeficacia. Los hallazgos señalan la necesidad de estudiar desde una perspectiva diferencial la participación de los pacientes en la toma de decisión de acuerdo con los procesos psicológicos, así como la repercusión que esta tiene en la adherencia al tratamiento médico.This study analyzed the role of psychological processes predicting depressed patients’ preferences in clinical decision-making about psychiatric treatment. 462 patients diagnosed with depressive disorders, acute or recurrent, participated in a crosssectional survey. Most participants preferred collaborative-passive or totally passive roles. Results showed no significant differences between acute and recurrent patients in their preference of participation in decision-making, but longer treatment duration was associated with a more passive style. MANCOVA, controlling age, educational level and treatment duration variables, showed that collaborative and passive patients had a greater locus of control focused on their psychiatrist than active patients. Gender differences were found. Men showed greater internal locus of control and psychological reactance, while women showed greater external locus of control focused on chance. Regression analysis indicated that, for men, passive preferred role was explained by external locus centered on their psychiatrist. However, age registered the highest weight for women’ passive decision-making, followed by the locus focused on chance, locus focused on the psychiatrist and lower self-efficacy. Our findings suggest the need to study shared decision-making from a differential perspective that involves psychological processes and the impact of these processes in adherence to medical treatments

New insights of the local immune response against both fertile and infertile hydatid cysts

Background Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm Echinococcus granulosus. Within the viscera of the intermediate host, the metacestode grows as a unilocular cyst known as hydatid cyst. This cyst is comprised of two layers of parasite origin: germinal and laminated layers, and one of host origin: the adventitial layer, that encapsulates the parasite. This adventitial layer is composed of collagen fibers, epithelioid cells, eosinophils and lymphocytes. To establish itself inside the host, the germinal layer produces the laminated layer, and to continue its life cycle, generates protoscoleces. Some cysts are unable to produce protoscoleces, and are defined as infertile cysts. The molecular mechanisms involved in cyst fertility are not clear, however, the host immune response could play a crucial role. Methodology/Principal findings We collected hydatid cysts from both liver and lungs of slaughtered cattle, and histological sections of fertile, infertile and small hydatid cysts were stained with haematoxylin-eosin. A common feature observed in infertile cysts was the disorganization of the laminated layer by the infiltration of host immune cells. These infiltrating cells eventually destroy parts of laminated layer. Immunohistochemical analysis of both parasite and host antigens, identify these cells as cattle macrophages and are present inside the cysts associated to germinal layer. Conclusions/Significance This is the first report that indicates to cell from immune system present in adventitial layer of infertile bovine hydatid cysts could disrupt the laminated layer, infiltrating and probably causing the infertility of cyst

Assessments of the Extent to which Health‐Care Providers Involve Patients in Decision Making: A Systematic Review of Studies Using the OPTION Instrument

Background: We have no clear overview of the extent to which health-care providers involve patients in the decision-making process during consultations. The Observing Patient Involvement in Decision Making instrument (OPTION) was designed to assess this. Objective: To systematically review studies that used the OPTION instrument to observe the extent to which health-care providers involve patients in decision making across a range of clinical contexts, including different health professions and lengths of consultation. We conducted online literature searches in multiple databases (2001-12) and gathered further data through networking

Implementing shared decision-making in nutrition clinical practice: A theory-based approach and feasibility study

<p>Abstract</p> <p>Background</p> <p>There are a growing number of dietary treatment options to choose from for the management of many chronic diseases. Shared decision making represents a promising approach to improve the quality of the decision making process needed for dietary choices that are informed by the best evidence and value-based. However, there are no studies reporting on theory-based approaches that foster the implementation of shared decision making in health professions allied to medicine. The objectives of this study are to explore the integration of shared decision making within real nutritional consultations, and to design questionnaires to assess dieticians' intention to adopt two specific behaviors related to shared decision making using the Theory of Planned Behavior.</p> <p>Methods</p> <p>Forty dieticians will audiotape one clinical encounter to explore the presence of shared decision making within the consultation. They will also participate to one of five to six focus groups that aim to identify the salient beliefs underlying the determinants of their intention to present evidence-based dietary treatment options to their patients, and clarify the values related to dietary choices that are important to their patients. These salient beliefs will be used to elaborate the items of two questionnaires. The internal consistency of theoretical constructs and the temporal stability of their measurement will be checked using the test-retest method by asking 35 dieticians to complete the questionnaire twice within a two-week interval.</p> <p>Discussion</p> <p>The proposed research project will be the first study to: provide preliminary data about the adoption of shared decision making by dieticians and theirs patients; elicit dieticians' salient beliefs regarding the intention to adopt shared decision making behaviors, report on the development of a specific questionnaire; explore dieticians' views on the implementation of shared decision making; and compare their views regarding the implementation of shared decision making in different clinical settings.</p> <p>It is anticipated that the results generated by the proposed research project will significantly contribute to the emergence of shared decision making in nutrition through a theory-based approach.</p

Feasibility of a randomised trial of a continuing medical education program in shared decision-making on the use of antibiotics for acute respiratory infections in primary care: the DECISION+ pilot trial

Abstract Background The misuse and limited effectiveness of antibiotics for acute respiratory infections (ARIs) are well documented, and current approaches targeting physicians or patients to improve appropriate use have had limited effect. Shared decision-making could be a promising strategy to improve appropriate antibiotic use for ARIs, but very little is known about its implementation processes and outcomes in clinical settings. In this matter, pilot studies have played a key role in health science research over the past years in providing information for the planning, justification, and/or refinement of larger studies. The objective of our study was to assess the feasibility and acceptability of the study design, procedures, and intervention of the DECISION+ program, a continuing medical education program in shared decision-making among family physicians and their patients on the optimal use of antibiotics for treating ARIs in primary care. Methods A pilot clustered randomised trial was conducted. Family medicine groups (FMGs) were randomly assigned, to either the DECISION+ program, which included three 3-hour workshops over a four- to six-month period, or a control group that had a delayed exposure to the program. Results Among 21 FMGs contacted, 5 (24%) agreed to participate in the pilot study. A total of 39 family physicians (18 in the two experimental and 21 in the three control FMGs) and their 544 patients consulting for an ARI were recruited. The proportion of recruited family physicians who participated in all three workshops was 46% (50% for the experimental group and 43% for the control group), and the overall mean level of satisfaction regarding the workshops was 94%. Conclusions This trial, while aiming to demonstrate the feasibility and acceptability of conducting a larger study, has identified important opportunities for improving the design of a definitive trial. This pilot trial is informative for researchers and clinicians interested in designing and/or conducting studies with FMGs regarding training of physicians in shared decision-making.

Patients' preferences for involvement in treatment decision making in Japan

BACKGROUND: A number of previous studies have suggested that the Japanese have few opportunities to participate in medical decision-making, as a result both of entrenched physician paternalism and national characteristics of dependency and passivity. The hypothesis that Japanese patients would wish to participate in treatment decision-making if adequate information were provided, and the decision to be made was clearly identified, was tested by interview survey. METHODS: The subjects were diabetic patients at a single outpatient clinic in Kyoto. One of three case study vignettes (pneumonia, gangrene or cancer) was randomly assigned to each subject and, employing face-to-face interviews, the subjects were asked what their wishes would be as patients, for treatment information, participation in decision-making and family involvement. RESULTS: 134 patients participated in the study, representing a response rate of 90%. The overall proportions of respondents who preferred active, collaborative, and passive roles were 12%, 71%, and 17%, respectively. Respondents to the cancer vignette were less likely to prefer an active role and were more likely to prefer family involvement in decision-making compared to non-cancer vignette respondents. If a physician's recommendation conflicted with their own wishes, 60% of the respondents for each vignette answered that they would choose to respect the physician's opinion, while few respondents would give the family's preference primary importance. CONCLUSIONS: Our study suggested that a majority of Japanese patients have positive attitudes towards participation in medical decision making if they are fully informed. Physicians will give greater patient satisfaction if they respond to the desire of patients for participation in decision-making
