Abstract: An apparatus for aiding successful outpatient orthopedic surgery includes a communication interface, a memory, and a processor. The memory stores data representative of a plurality of physiological characteristics that are considered in determining suitability of a patient for outpatient orthopedic surgery, and further stores data representative of a plurality of associated weighted values. Each associated weighted value corresponds to a respective physiological characteristic. The processor determines whether a particular patient is suitable for outpatient orthopedic surgery by calculating a suitability value based on one or more identified weighted values, from among the plurality of associated weighted values, corresponding to one or more identified physiological characteristics which the particular patient exhibits. The suitability value is compared with one or more predetermined standard values related to suitability of a patient for outpatient orthopedic surgery.
