The main questions it aims to answer are:* To assess the effectiveness of CGM compared with conventional monitoring in reducing the comprehensive complication index (CCI) for patients with diabetes or impaired glucose tolerance (IGT) within 30 days after surgery.* To analyze the impact of different age groups, types of surgery, preoperative levels of HbA1c, and preoperative 24h glycemic variations on the improvement of surgical outcomes under the CGM model.Participants will receive CGM prescribed by the attending physician for at least 6 hours before surgery. Glucose monitoring should be continued until the 7th day after surgery or discharge.The investigators will compare conventional monitoring group to see if CGM could reduce the CCIs for patients with diabetes or impaired glucose tolerance within 30 days after surgery., conditionsModule conditions: Comprehensive Complication Index, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, whoMasked: OUTCOMES_ASSESSOR, enrollmentInfo count: 10168, type: ESTIMATED, armsInterventionsModule interventions name: Continuous glucose monitoring (CGM) device, outcomesModule primaryOutcomes measure: Comprehensive complication index, secondaryOutcomes measure: Postoperative complications, secondaryOutcomes measure: Morality, secondaryOutcomes measure: The length of the stay in the intensive care unit, secondaryOutcomes measure: The length of hospital stay, secondaryOutcomes measure: The overall hospitalization cost, secondaryOutcomes measure: Perioperative glucose level, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Zhifeng Gao, status: RECRUITING, city: Beijing, state: Beijing, zip: 102218, country: China, contacts name: Zhifeng Gao, MD, role: CONTACT, phone: 18756235568, email: btchgzf@hotmail.com, geoPoint lat: 39.9075, lon: 116.39723, hasResults: False
