[Guidelines: leash or walking stick?]

Guidelines are undeniably of great value to practicing physicians, but there are also objections. Due to the multitude of guidelines, it is sometimes difficult to find the most appropriate and it is not always clear how well-founded recommendations are. In addition, guidelines can limit the freedom of action. Also, in individual patients - especially in the case of multimorbidity - recommendations from different guidelines can conflict with each other. Finally, drawing up guidelines takes a lot of time, which is at the expense of patient care, and conflicts of interest are difficult to avoid completely. It is therefore important to put the recommendations from guidelines into perspective: they are an aid to individual patient care, not a law. This perspective is also important in education, so that students are taught to use guidelines in a wise way. Finally, it is important to regularly evaluate recommendations and revise them if necessary.
