[Experience of a single-centre in the preparation of choosing wisely lists in Internal Medicine]

To identify areas for improvement, using a local list of interventions with low diagnostic and therapeutic usefulness for the 5 Related Diagnostic Groups, as well as the 5 main diagnoses most frequently seen in the hospital outpatient clinic.

A literature review method was used, supplemented with a Delphi process with 2 rounds. In the first round, participants in the selection process identified low-value interventions in relation to the most frequently observed diagnoses. In the second round, those interventions with lower usefulness were selected based on their frequency, cost, and risk to the patient.

Out of a total of 100 recommendations made by 19 scientific societies, 23 received the highest number of votes in the first round. In the second round, 5 recommendations were selected for inpatients and 5 recommendations for outpatients.

A simple method is described for developing a local guide to reduce the use of unnecessary medical interventions.
