Study design and patients

In a prospective multicentric interventional study, patients where endoscopic sinus procedures were planned at the Center for Otorhinolaryngology, Head and Neck Surgery, Klinik Hirslanden, Zurich, the Department of Otolaryngology, Head and Neck Surgery, Luzerner Kantonsspital, Lucerne and HNO-Klinik München-Bogenhausen, Munich, in the period between January 1st 2017 and December 31st 2018 were evaluated. Due to the structure of the health care system in these centers, patients were admitted with a minimal hospital stay of 24 h. Patients below the age of 18 were excluded. Patient specific data (patient age, gender), the type of the procedure, the preoperative risk score or “day surgery risk score”, postoperative complications during the first 14 days and the length of hospital stay were analyzed. Data collection was performed using “ENTstatistics” software (ENTstatistics, Innoforce, LI-9491 Ruggel, Liechtenstein).
