Abstract
BackgroundThere has been little systematic research about the extent to which German physicians accept or reject the concept and practice ofa) clinical practice guidelines (CPG) andb) evidence based medicine (EBM)The aim of this study was to investigate German office-based physicians' perspective on CPGs and EBM and their application in medical practice.MethodsStructured national telephone survey of ambulatory care physicians, four thematic blocks with 21 questions (5 point Likert scale). 511 office-based general practitioners and specialists. Main outcome measures were the application of Clinical Practice Guidelines in daily practice, preference for sources of guidelines and degree of knowledge and acceptance of EBM. In the data analysis Pearson's correlation coefficient was used for explorative analysis of correlations. The comparison of groups was performed by Student's t-test. Chi2 test was used to investigate distribution of two or more categorical variables.ResultsOf the total study population 55.3% of physicians reported already using guidelines in the treatment of patients. Physicians in group practices (GrP) as well as general practitioners (GP) agreed significantly more with the usefulness of guidelines as a basis for patient care than doctors in single practices (SP) or specialists (S) (Student's t-test mean GP 2.57, S 2.84, p < 0.01; mean GrP 2.55, SP 2.80, p < 0.05). 33.1% of the participants demonstrated a strong rejection to the application of guidelines in patient care. Acceptance of guidelines from a governmental institution was substantially lower than from physician networks or medical societies (36.2% vs. 53.4% vs. 62.0%). 73.8% of doctors interpret EBM as a combination of scientific research and individual medical knowledge; 80% regard EBM as the best basis for patient care.ConclusionDespite a majority of physicians accepting and applying CPGs a large group remains that is critical and opposed to the utilization of CPGs in daily practice and to the concept of EBM in general. Doctors in single practice and specialists appear to be more critical than physicians in group practices and GPs. Future research is needed to evaluate the willingness to acquire necessary knowledge and skills for the promotion and routine application of CPGs.

Summary
There has been little systematic research about the extent to which German physicians accept or reject the concept and practice of a) clinical practice guidelines (CPG) and b) evidence based medicine (EBM)The aim of this study was to investigate German office-based physicians' perspective on CPGs and EBM and their application in medical practice. There has been little systematic research about the extent to which German physicians accept or reject the concept and practice of a) clinical practice guidelines (CPG) and b) evidence based medicine (EBM). Clinical decisions of everyday patient care are based on scientific medical knowledge as well as personal experience of the practicing physician. The concept of evidence based medicine (EBM) as "the conscientious, explicit, and judicious use of current best evidence" and "integration of individual clinical expertise" [3] offers a theoretical framework to combine scientifically generated knowledge and personal experience. Evidence based Clinical Practice Guidelines (CPG) are seen as a cornerstone and as important tools for the implementation and dissemination of the concept of EBM [8,9]. CPGs are promoted as key instruments for health care improvement in most industrialized countries
