BackgroundLiving wills/advance directives (AD) are an important tool for specifying patient wishes regarding medical care in the case of future inability to consent. Since 2009, German legislation defines framework conditions for the creation and validity of such directives in § 1901a BGB.MethodsAn extensive literature search in an international and a German-language database was conducted to identify, analyze, and evaluate scientific articles on opportunities, risks, and problems in the creation and implementation of living wills.ResultsBetween 10 and 40% of patients have an AD. Among the stipulations in the AD, the demand for sufficient pain therapy is very important. However, numerous problems in the preparation and implementation of ADs reduce their value in everyday clinical practice. In particular, unclear conditions of validity, unspecific instructions for action, and lack of availability of the directives prevent practitioners from determining the patient's will. Other fundamental problems include frequent patient ambivalence and clinical ethical dissent. In addition, the framework condition of unlimited coverage set by the law carries the risk that changes of opinion in the course of life or disease are not taken into account.ConclusionPreparing an AD requires a high level of information, consultation, and time, as well as regular review or adjustment of its content. These factors are often not considered, thus complicating implementation and reducing the value of living wills. Possible solutions to these problems or alternative concepts for different patient settings are discussed in this review.© 2023.
