What is the follow-up record of health status?

What is the follow-up record of health status? This is a hospital with a registration form, which tracks the patient's number, the patient's health status and the recovery stage. For example, when a patient is hospitalized during the recovery period of surgery, she will basically go back. When she returns home and has a healthy condition, the follow-up records will say his health condition after surgery, his recovery condition after surgery, some repair conditions after surgery, and some problems left over from surgery. Therefore, health status follow-up records are needed.
