Discussion Quotations are important for the message of the quoting paper. Therefore, quotation errors may be detrimental to scientific reasoning and may undermine public trust in medical science. The present investigation is a case study, and its results are exploratory. While it is plausible that the findings translate into other environments, independent replication is needed.Introduction In potentially curable non-small-cell lung cancer, different practice guidelines recommend invasive me-diastinal staging in tumors larger than 3 cm, central, or hy-permetabolic N1 lymph nodes. There is no consensus concerning the use of an endosonographic procedure or a mediastinoscopy in the first line in patients with a radiologically normal mediastinum, while in case of a mediastinal involvement, the latest European guidelines recommend the combination of endobronchial ultrasound (EBUS) and endoscopic ultrasound/endoscopic ultrasound with EBUS endoscope (EUS/EUS-B), using a systematic endosonographic procedure. This international survey was conducted to describe current medical practices in endoscopic mediastinal staging amongst interventional bronchoscopists. Methods A survey was developed and sent to all members of different interventional pulmonology societies, with the purpose to describe who, when and how an endoscopic mediastinal staging was performed. Results One hundred and fifty-threeers. A fellowship program appears to be associated with a higher rate of systematic endoscopic staging procedures.Background Addiction Consult Services care for hospitalized patients with substance use disorders (SUD), who frequently utilize costly medical services.
