Outpatient Procedure

A medical or surgical intervention completed in a single day with the patient discharged home, without an overnight stay. Advances in anesthesia and minimally invasive technique have shifted many procedures, from cataract surgery to arthroscopy, into ambulatory surgery centers for lower cost and faster recovery.

What is an outpatient procedure?

An outpatient procedure is a medical or surgical intervention that is completed in a single day, with the patient discharged home afterward and no overnight stay. It can range from minor interventions to fairly involved surgeries, as long as recovery does not require inpatient admission.

What makes a procedure outpatient is the same-day discharge rather than the nature of the operation itself. Improvements in anesthesia and minimally invasive techniques have steadily expanded the set of procedures that can be safely performed this way.

Why does this matter for ambulatory surgery centers?

The shift of procedures such as cataract surgery and arthroscopy into the outpatient setting has been a major driver of growth for ambulatory surgery centers. These cases can be done at lower cost and with faster recovery than the equivalent hospital admission.

Because outpatient procedures are the entire business of a surgery center, the ongoing migration of cases from inpatient to outpatient settings expands what these centers can offer. Each procedure that becomes safe to perform on a same-day basis represents potential new volume.
