Certain embodiments provide systems and methods for self-updating procedure duration estimation for patient scheduling. A scheduling system for scheduling procedures in a clinical environment includes historical procedure data including stored duration values for a procedure. The scheduling system also includes a user interface providing scheduling and procedure duration information to a user for scheduling the procedure for a patient. The scheduling system further includes a scheduling engine estimating one or more duration values for the procedure for scheduling the procedure for a patient. The scheduling engine establishes a default duration value for a procedure and updating the default duration value based on the historical procedure duration data. The scheduling engine provides a plurality of procedure durations including the updated default duration value to the user for selection via the user interface. The scheduling engine schedules a procedure using a user selected value for procedure duration.
