Development and first validation of the shared decision-making questionnaire (SDM-Q).

OBJECTIVE: Due to a lack of valid German instruments measuring shared decision-making (SDM), a theory-driven questionnaire (SDM-Q) to measure the process of SDM was developed and validated. METHODS: As a theoretical basis steps of the SDM process were defined in an expert panel. Item formulation was then conducted according to the Delphi method. For the first validation on a mixed sample Rasch analysis was used to eliminate items not fitting the construct thus receiving a unidimensional scale. RESULTS: After eliminating 4 items the remaining 11 form a unidimensional scale with an acceptable reliability for person measures (0.77) and very good reliability for item difficulties (0.95). Analysis of subgroups revealed a different use of items in different conditions. Furthermore the scale showed high ceiling effects. CONCLUSION: A new theory-driven instrument to measure the process of SDM has been developed and validated by use of a rigorous method revealing first promising results. Yet the ceiling effects require the addition of more discriminating items, and the different use of items in different conditions demands an in depth analysis. PRACTICE IMPLICATIONS: While the concept of SDM is constantly receiving more attention in medical practice, its valid and reliable measurement remains challenging.

[Effects of a shared decision making model in psychiatric and neurologic practice].

Involving patients in medical decisions is increasingly being advocated in medical fields other than psychiatry and neurology. A model of shared decision making might prove to be an ideal way of bridging the gap between patient-centred and evidence-based medicine. This report provides a survey of this shared decision making model and a discussion of its implications in the fields of mental health and neurology.

Preferences for shared decision making in chronic pain patients compared with patients during a premedication visit.

BACKGROUND: There is some evidence that patients' outcomes improve if they are involved in shared decision making (SDM). A chronic pain clinic or premedication visit could be adequate settings for the implementation of SDM. So far, the patients' preference for involvement in decision making and their desire for information have not been tested in anesthesiological settings. METHODS: A group of chronic pain patients was compared with a group of patients in the premedication visit with respect to SDM, the desire for information and perceived involvement in care. The autonomy preference index (API, measuring preference for involvement and desire for information) and the perceived involvement in care scale (PICS, measuring patients' perception of easier involvement by doctors and information exchange) were administered. RESULTS: In total, 190 chronic pain patients and 151 patients of premedication were included in this study. Patient of the premedication visit had significantly higher SDM scores. Desire for information was high, but there were no differences between groups. Younger patients [B (estimate) =- 0.3; 95% CI (-0.4) - (-0.1)], women (B = 10.9; 95% CI 6.3-15.4) and patients with higher educational level (B = 10.1; 95% CI 5.6-14.6) had more desire for SDM. PICS scores were basically influenced by groups: chronic pain patients felt more facilitated by doctors [B =- 0.185; 95% CI (-0.4) - (-0.1)] and had more information exchange [B =- 19.5; 95% CI (-15.8) - (-2.4)] than patients in the premedication visit. CONCLUSION: In both anesthesiological settings, the desire for information was high, but patients in the premedication visit had higher SDM scores, especially young female patients with higher educational level. Real patient-physician interaction showed that premedication patients felt less involved by doctors and had less information exchange compared with the chronic pain patients. Therefore, premedication visits should be focussed more on adequate information exchange and involvement of the patient in the shared decision making process.

[Development and validation of assessment instruments for shared decision making].

The German Ministry for Health and Social Security is funding ten projects to introduce shared decision making into clinical practice. The medical problems the projects are focussing on were chosen from among various diseases (e. g. depression, multiple sclerosis, cancer). The ten projects achieved consensus on a core set of instruments for the measurement of process and outcome of the shared decision making. Instruments developed in German-speaking countries are currently not available. Thus, linguistic and cultural validation had to be performed for the core set instruments. The results of the data analysis as well as patient interviews demonstrate the need for improving these instruments. Therefore, the members of the methodological working group concentrated on the integration of these results in a new instrument. In a first step the construct of "shared decision making" was defined, followed by a definition of the process elements characterising shared decision making. Thereafter, items were developed on the basis of the process elements. The new instrument will now be validated for different diseases.

Intercurrent complications in chronic alcoholic men admitted to the intensive care unit following trauma.

OBJECTIVE: A chronic alcoholic group following trauma was investigated to determine whether their ICU stay was longer than that of a non-alcoholic group and whether their intercurrent complication rate was increased. DESIGN: Prospective study. SETTING: An intensive care unit. PATIENTS: A total of 102 polytraumatized patients were transferred to the ICU after admission to the emergency room and after surgical treatment. Of these patients 69 were chronic alcoholics and 33 were allocated to the non-alcoholic group. The chronic-alcoholic group. met the DSM-III-R and ICD-10 criteria for alcohol dependence or chronic alcohol abuse/harmful use. The daily ethanol intake in these patients was > or = 60 g. Diagnostic indicators included an alcoholism-related questionnaire (CAGE), conventional laboratory markers and carbohydrate-deficient transferrin. MEASUREMENT AND RESULTS: Major intercurrent complications such as alcohol withdrawal syndrome (AWS), pneumonia, cardiac complications and bleeding disorders were documented and defined according to internationally accepted criteria. Patients did not differ significantly between groups regarding age, TRISS and APACHE score on admission. The rate of major intercurrent complications was 196% in the chronic alcoholic vs 70% in the non-alcoholic group (p = 0.0001). Because of the increased intercurrent complication rate, the ICU stay was significantly prolonged in the chronic-alcoholic group by a median period of 9 days. CONCLUSIONS: Chronic alcoholics are reported to have an increased risk of morbidity and mortality. However, to our knowledge, nothing is known about the morbidity and mortality of chronic alcoholics in intensive care units following trauma. Since chronic alcoholics in the ICU develop more major complications with a significantly prolonged ICU stay following trauma than non-alcoholics, it seems reasonable to intensify research to identify chronic alcoholics and to prevent alcohol-related complications.
