Preoperative Hypoglycemia and Hyperglycemia Are Related to Postoperative Infection Rates in Implant-Based Breast Reconstruction.
Diabetic patients undergoing surgery are known to have a higher risk for infection. However, current literature does not adequately investigate the effects of preoperative hypoglycemia or hyperglycemia on postoperative infection risk. A retrospective review of a national private payer database within the PearlDiver Supercomputer application (Warsaw, IN) for patients undergoing breast reconstruction with implant/expander (BR) was conducted. These patients were identified by Current Procedural Terminology (CPT) and International Classification of Disease (ICD-9) ninth revision codes. Glucose ranges were identified by filtering for Logical Observation Identifiers Names and Codes ranging from 25 to 219 mg/dL, in 15 mg/mL increments. Patients with preexisting diabetes diagnoses were excluded. These patients were longitudinally tracked for infection at the 90 d and 1-y postoperative period using ICD-9 codes. The search query yielded 13,237 BR procedures with preoperative glycemic levels ranging from 25 to 219 mg/mL. Most procedures (34.6%) were performed on patients with preoperative glycemic levels ranging from 70 to 99 mg/dL. Of the total procedures performed (n = 13,237), 19.4% (n = 2564) resulted in infections documented at the 90-d interval, and 24.8% (n = 3285) resulted in infections documented at the 1-y interval. BR patients within the 40-54 mg/dL range had the highest rate of infection (90 d: 30.1%; 1 y: 53.4%). There was a statistically higher incidence of infection among patients with preoperative hypoglycemia (<70 mg/dL). The incidence of infection remains high in preoperatively hyperglycemic patients undergoing breast reconstruction procedures. However, our results show that preoperatively hypoglycemic patients also have an increased incidence of infection.
