Abstract: Background The operating room (OR) is characterized by highly specialized processes and high demands on quality and safety concerning patient treatment. This makes the OR the most expensive department of a typical hospital. As at the same time, the OR generates the biggest revenue stream, efficiency is of paramount importance. While this need for both quality and efficiency has already led to Lean initiatives in hospital wards over the last number of years, the Lean optimizations in OR settings are rarely discussed. Objectives The aim of this paper is to assess the current state of knowledge on OR improvement approaches to highlight research gaps within the field of Lean health research and thus determine future research opportunities. Method We conducted an extensive literature research on OR improvement and categorized the relevant literature according to research approaches. Further, we applied the Proficiency-Willingness-Empowerment (PWE) framework to understand the topics discussed. Finally, we categorized the Lean tools/principles found and compared them to the ones used in Lean optimizations outside the OR. Results The majority of papers shows methodological deficits, as they often lack robust generalizable evidence or are purely mathematical models without real evidence of applicability in practice. Further, many papers focus on the hard factors of OR optimizations, while very few deal with soft factors like change management and team culture. The single most discussed tool/principle of OR optimization concerns scheduling, while other typical aspects of Lean optimizations such as standardization and security procedures receive minor attention. Research Proposition Based on the review, we identified three research propositions. First, researchers should combine deductive and inductive approaches to better understand practitioners’ challenges in OR settings. Second, the management research community should emphasize more the soft factors of OR transformations and focus on leadership’s role and required competences in OR optimization settings. Third, as the research on OR optimization tools/principles is still in its early stages, we need to develop a Lean-OR specific toolbox and transformation concept to facilitate future OR improving initiatives.
