The Prevalence of Hyperglycemia in Surgical Patients With Pre-diabetes

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.
