I believe that if we know what time a person is going home from a skilled rehabilitation facility that the doctor should gradually take them off the pain medication before release. When the patient first arrives every 4 hours after surgery is fine, but as the release date comes closer the time between pain medications should be increasing. They need to be weaned off the medication or close to it before they leave. By the time they leave every 8-12 hours as needed for pain. I believe it would help.
