Study Overview
Brief Summary
The goal of this study is to measure the prevalence and risks of hyperglycemia in surgical patients with prediabetes. The main questions it aims to answer are:
- What is the prevalence of hyperglycemia in surgical patients with prediabetes?
- What is the relative risk of postoperative complications associated with hyperglycemia?
To answer these questions, surgical patients with prediabetes will undergo universal glucose measurement in the perioperative period. Glucose data will be analyzed in conjunction with electronic health record (EHR) data describing patient outcomes.
Detailed Description
Background
Day-of-surgery and postoperative ('perioperative') hyperglycemia are modifiable risk factors for complications after non-cardiac surgery, including surgical site infections, 30-day readmissions, and mortality. Data from Alberta suggests perioperative hyperglycemia is common among people without diabetes, affecting about 13% of people with prediabetes on the day-of-surgery and 18% of people without diabetes after surgery. Paradoxically, the risks of perioperative hyperglycemia appear to be two-times greater for people with prediabetes than for people with diabetes and the reasons for this are unknown. Current estimates of the prevalence of perioperative for people with prediabetes are limited. Understanding the true prevalence would inform individual decision-making around surgery, the need for further research about the true association of hyperglycemia and adverse outcomes, and clinical decisions about the utility of measuring glucose for all people with prediabetes around the time of surgery.
Objectives
This prospective cohort study will establish the prevalence of perioperativehyperglycemia in people with prediabetes undergoing scheduled (elective and urgent) non-cardiac surgeries. This information will inform:
- Patients, to better understand their individual risks of elective surgery.
- Clinicians, on the need for perioperative glucose measurement for patients with prediabetes.
- Researchers, on the need for and design of further studies.
