Periodic review on outpatient and inpatient medical records means that some tests need to be tested at intervals so that you can know whether your condition is getting better or progressing so that you can treat it in a timely manner. Many diseases are not completely better when they are discharged from the hospital, such as hypertension, hyperlipidemia, diabetes and other chronic diseases. These diseases need regular rechecks of blood pressure, blood lipids, and blood sugar indicators to see if they are up to standard after long-term medication, so that oral medications can be adjusted in a timely manner. At the same time, some diseases have a high recurrence rate, such as tumors and cardiovascular diseases. Tumor diseases often require a more comprehensive review every 3 to 6 months after treatment to observe whether recurrence and metastasis. Regular review of risk factors for cardiovascular diseases is also very important to prevent recurrence of cardiovascular diseases. Therefore, the review is of great significance in observing the progress of the disease and preventing recurrence. We hope that patients who need to undergo regular review will do so in accordance with their doctor’s recommendations.
