This thesis presents an attempt to assess how prediction about patients' expected stay in the operating room, intensive care and postoperative surgical units could be used in the process of scheduling of patients for cardiac surgery. The study was carried out in the setting of the University of Ottawa Heart Institute (OHI) where current scheduling practices and the process of flow of patients through surgery were studied. Data were collected from all patients who underwent cardiac surgery at the University of Ottawa Heart Institute during the 1994 and 1995 calendar years. Information of interest is the relation of demographic, clinical and procedural factors for each patient to the time of operation, length of stay in the intensive care unit after surgery, length of postoperative stay until discharge from the hospital and in-hospital mortality after surgery. As a result of the analysis of the University of Ottawa Heart Institute surgical scheduling system and patient data we (i) understood how the current system is operating, (ii) developed and assessed models for predicting length of stay in ICU after cardiac surgery.
