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(More)
PURPOSE We wanted to determine the effect of promoting the effective communication of absolute cardiovascular disease (CVD) risk and shared decision making through disseminating a simple decision aid for use in family practice consultations. METHODS The study was based on a pragmatic, cluster randomized controlled trial (phase III) with continuing medical(More)
BACKGROUND/OBJECTIVE Chest pain is a common complaint and reason for consultation. We aimed to study the epidemiology of chest pain with respect to underlying aetiologies and to establish pre-work-up probabilities for the primary care setting. METHODS We included 1212 consecutive patients with chest pain, aged 35 years and older, attending 74 general(More)
BACKGROUND In patients with chest pain, GPs have to identify those with coronary heart disease (CHD) to arrange for further investigation and treatment. Previous studies have shown that only between 8% and 18% of patients have CHD. In primary care, the history is the most important diagnostic tool. However, there are only few studies exploring diagnostic(More)
BACKGROUND The correspondence of satisfaction ratings between physicians and patients can be assessed on different dimensions. One may examine whether they differ between the two groups or focus on measures of association or agreement. The aim of our study was to evaluate methodological difficulties in calculating the correspondence between patient and(More)

DESIGN Cross-sectional assessment of physician-patient interaction by two rater pairs and two experts in shared(More)

AIM In shared decision-making, patients are empowered to actively ask questions and participate in decisions about their healthcare based on their preferences and values. Decision aids should help patients make informed choices among diagnostic or treatment options by delivering evidence-based information on options and outcomes; however, they have rarely(More)
BACKGROUND Chest wall syndrome (CWS) is the most frequent aetiology of chest pain in a primary care setting. OBJECTIVE The aims of the study are to describe the epidemiology, clinical characteristics and prognosis of CWS and to provide a simple decision rule for diagnosis. METHODS We included 1212 consecutive patients with chest pain aged 35 years and(More)
