The proportion of patients with non-escalation of discharge of level of care will be assessed by comparing the level of care of the location that the patient was living preoperatively to the level care to the location that the patient is discharged and will be considered present if the discharge level of care is the same or lower. Levels of care from highest to lowest are: long term acute care hospital > skilled nursing facility > rehabilitation center > assisted living > unassisted home living.
