The high volume of resources associated with the operating theatre of a hospital, makes the surgical centre a space of real importance in its organization. In this project we have determined the degree of variability associated with the duration of major surgeries of the mastology area of the Hospital de Câncer III of INCA (Instituto Nacional de Câncer), in order to reduce the uncertainty associated with the delay of the surgeries, and to make schedules (surgical maps) that possess greater robustness with later execution. We studied factors associated with the patient (IMC, hypertension, diabetes), surgeon (gender, age, trimester surgical team composition and time of day that begins the surgery) and the procedure itself (Linfonodo Biopsy Sentinel, expansion of margins and axillary lymphadenectomy) in order to establish a linear regression equation to predict more accurately the duration of future surgeries. For this we have obtained a random sample of medical files of the years 2010, 2011 and 2012. Some of the factors included rebelled as significant in exploratory data analysis, in tests of hypotheses and in selecting variables in the regression equation (Stepwise Selection). However, the amount of variability explained is moderate.
