Abstract：
BACKGROUND: Published in 2009, the German S3 guidelines on dementia define a milestone in quality improvement of the diagnostics and treatment of dementia. In clinical practice patients suffering from dementia are primarily treated by physicians in private practice; therefore, this study examined how the guidelines are implemented in outpatient clinical settings. Furthermore, it aimed at the identification of behavioral determinants that govern the actual diagnostic and therapeutic approach in clinical practice.
METHODS: Physicians involved in the primary care of dementia patients were asked to participate in a nationwide internet survey. The questionnaire covered aspects on the diagnostic and therapeutic care of dementia patients as recommended by the S3 guidelines. Behavioral determinants of the implementation of the guidelines (e. g. treatment decisions) were derived from an established psychological prediction model.
RESULTS: Out of a total of 2755 physicians contacted, the data of 225 participants could be used in this study. The diagnostic recommendations of the S3 guidelines were implemented in satisfactory measures (e.g. combined cognitive screening in at least 68%, cerebral neuroimaging in at least 93% and specific laboratory diagnostics in at least 27% of cases); however, only two thirds of the patients with indications for a guideline-conform therapy were treated in accordance with the S3 guidelines. There was a substantial prescription of non-recommended drugs and a notable long-term use of antipsychotic drugs (prescription by at least 14% of non-neurological medical specialists and by 8% of neurologists and psychiatrists). When considering the behavioral determinants in the implementation of the guidelines, normative assumptions (\"my colleagues and patients expect me to comply with the guidelines\") surprisingly had the highest impact, which was then followed by attitudes towards the behavior (\"utilization of the guidelines improves diagnostics and therapy\").
CONCLUSIONS: The German S3 guidelines on dementia were satisfactorily implemented in outpatient clinical practice; however, deficits existed in the frequency of the pharmaceutical treatment of patients with indications for therapy, the prescription of non-recommended drugs and the relatively common use of permanent neuroleptic medications. Interestingly, the motivation for implementation of the guidelines was not primarily influenced by the physicians\' personal convictions but mainly stimulated by the expectations of others.
