Assessment for Perioperative Hyperglycemia Prior to Total Joint Replacement in Patients With and Without Diabetes

More than 1 000 000 total joint replacements (TJRs) are performed annually in the United States,¹ most of which are for osteoarthritis.² Diabetes is a frequent comorbidity in patients with osteoarthritis³ and suboptimal glucose control preoperatively is associated with poor TJR outcomes.^4,5 Despite the concern for hyperglycemia in the period before TJR, there is a paucity of data regarding the frequency of preoperative outpatient screening. We aimed to assess how frequently hemoglobin A_1c (HbA_1c) was measured 90 days prior to TJR among Medicare enrollees.
