Zusammenfassung

In den letzten Jahren sind große wissenschaftliche Fortschritte bei der Entwicklung methodischer Ansätze zur Effizienzmaximierung von Operationseinrichtungen durch Zuweisung und Planung von Operationsraumkapazitäten gemacht worden. In diesem Beitrag wird eine solche Methode vorgestellt. Sie nutzt die Analyse historischer Daten zur chirurgischen Tätigkeit operativer Einrichtungen, um den zukünftigen Bedarf vorherzusagen und zu planen. Integraler Bestandteil der Methode sind Grundsätze und Regeln, die für die tägliche Organisation und das operative Management des Operationsbetriebes notwendig sind. Sie sind ebenfalls wissenschaftlich begründet und bieten so eine rationale und strukturierte Grundlage für alle notwendigen Entscheidungen. Dabei werden medizinische Aspekte wie die Patientensicherheit und freie Wahl des Operationstages gegenüber dem ökonomischen Ziel der Maximierung der Operationsraumeffizienz priorisiert.

Abstract

During the past decade many scientific advances have been made concerning the development of methodologies to maximize efficiency of surgical facilities through allocating and scheduling of operating rooms. In this article such a methodology is described. Using the analysis of historical data of surgical activity in a facility, future demand is predicted and planned. Part of the methodology includes principles and rules needed for the daily organization and operative management of surgical facilities. They are also derived from the same science and therefore the basis for rational and structured decision making. Medical aspects such as patient safety and free choice of day for surgery have higher priority than the economic goal of maximizing operating room efficiency.
