The success of surgery for the patient depends fundamentally on the collaboration among the various professional groups involved. This encompasses not only cooperation between operating room nursing staff and the surgeon, but also includes numerous other professions such as anesthesia, cleaning staff, supply services, and laboratory personnel. Collaboration begins with the planning of the operation and extends through to the successful postoperative care of the patient. Organizational, diagnostic, hygienic, and legal aspects must all be taken into account. Optimized teamwork ensures a significant reduction in operating time and helps prevent complications. All of these factors contribute to the successful care of each individual patient. Clear and unambiguous communication among the different professional groups and departments is essential.
