Analysis of surgical procedures is an emerging domain of medical engineering aimed at advancing surgical assist systems. The term Surgical Workflows is used for describ- ing the methodicalframework for acquiringformal descrip- tions of surgical interventions. A formal model and a uni- form recording scheme of a surgical process are crucial for systematic accumulation of relevant data from running sur- gical instances in a form, appropriate for analysis. This pa- per describes the process of designing a data warehouse for surgical workflow analysis. Data warehousing technology, originally developed for quantitative business data analy- sis for the purpose of decision making, is adaptable to the requirements of surgical data and analysis. We describe a conceptual model of a surgical procedure obtained in ac- cordancewith the multidimensionaldata model. We demon- strate how a subject-oriented multidimensional perspective of a surgery and its components enables powerful analysis and exploration by defining the metrics of interests and ag- gregating those metrics along various dimensions and lev- els of details. Apart from its primary function, i.e. quantita- tive analysis, the data of the surgical data warehouse may serve as input for other data-intensive systems, e.g. visual- ization and data mining tools.
