Incidence of Undiagnosed and Poorly Controlled Diabetes Mellitus Among Surgical Patients and Its Association With Perioperative Outcomes: a Single-centre Prospective Cohort Study

Brief Summary

Detailed Description

The study aims to determine the incidence of undiagnosed and poorly controlled diabetes among surgical patients in Singapore using preoperative HbA1c as a screening tool. The investigators aim to follow up on the incidence of perioperative complications in this cohort. In the longer term, the investigators hope to evaluate the role of a preoperative diabetic screening and intervention program as an opportunistic "teachable moment" for surgical patients. This may help to achieve greater control of the disease burden in Singapore. Specific aims: Specific Aim 1: To establish the incidence of undiagnosed diabetes/prediabetes among surgical patients in Singapore, based on HbA1c level ≥ 6.1% prior to surgery Specific Aim 2: To establish the incidence of poorly-controlled diabetes among surgical patients in Singapore, based on HbA1c level ≥ 8% prior to surgery Specific Aim 3: To identify and characterize any association between preoperative HbA1c level and postoperative outcomes
