[Response to and further development of the Choosing wisely initiative]

The Choosing wisely initiative of the German Society of Internal Medicine ("Deutschen Gesellschaft für Innere Medizin," DGIM) and its 12 core focus area specialist societies were brought into being in 2014. The German initiative differs from the American campaign in that it not only considers overuse of diagnostic and therapeutic healthcare services, but also addresses procedures which are frequently not performed although they would bring benefits for patients. Furthermore, the recommendations were approved by an interdisciplinary consensus commission under consideration of all key internal medicine aspects. Since 2014, the initiative has received widespread attention. The 115 recommendations approved by the consensus commission have meanwhile been published in 20 articles. An array of measures were subsequently adopted to further promote the Choosing wisely recommendations ("Klug-entscheiden-Empfehlungen," KEE). These include the systematic incorporation of KEE symposia into DGIM annual congresses and the congresses of the core focus area specialist societies, as well as consideration of the KEE during establishment of future guidelines. Particular attention was paid to the importance of initiating and promoting a research project aimed at familiarizing medical students with the principles and content of the Choosing wisely initiative. The decision for or against specific diagnostic and therapeutic procedures represents an essential medical competence, which should therefore be trained prior to qualification.
