Final answer:
A retrospective review is conducted when a patient is discharged, examining the care received and ensuring it met the required standards after services have been delivered.
Step-by-step explanation:
When a patient is discharged, the type of review completed is typically a retrospective review. This involves looking back at the medical care provided to assess the adequacy of care, adherence to care standards, and to evaluate the necessity of the services provided. The term retrospective is key because the review occurs after services have been delivered, as opposed to a prospective review, which occurs before or at the time of service, or a concurrent review, which happens while the patient is still receiving care.
