About

Our study aims to determine the incidence of undiagnosed and poorly controlled diabetes among surgical patients in Singapore using preoperative HbA1c as a screening tool.

Full 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

Cohort

Description:

We propose a prospective, observational single-centre pilot study in the PAC (SGH), on participants aged 21 years and above. A HbA1c test will be added to their routine preoperative blood tests. The incidence of newly-diagnosed DM/pre-diabetes (HbA1c ≥6.1%) and poorly controlled DM (HbA1c ≥ 8%), demographic details and presence of significant comorbidities will be analysed.

Treatment:

Other: HbA1C
