  "abstract": "Background and Objectives:: Surgical site infection (SSI) is an important complication following hysterectomy. Given the rising antimicrobial resistance in Iran, this multi-year cohort study aimed to identify independent predictors of SSI after hysterectomy.\n\nMaterials and Methods:: This retrospective cohort study included patients undergoing total abdominal hysterectomy (2019–2024). Independent risk factors were identified via multivariable binary logistic regression. Model performance was validated using receiver operating characteristic (ROC) curve analysis. Continuous variable cut-off points were determined using the Youden index.\n\nResults:: Among 690 patients, the SSI rate was 5.2%. Multivariable analysis identified obesity (BMI ≥ 30 kg/m2) (Adjusted Odds Ratio [aOR]: 4.11; 95% CI: 1.81–9.32; p < 0.001) and operative duration (aOR: 1.02 per minute; p < 0.001) as the strongest independent predictors. ROC analysis demonstrated excellent discrimination (AUC = 0.88). Infection risk increased critically when surgery exceeded 180 minutes or in obese patients. Preoperative non-standard antibiotic prophylaxis consisting solely of clindamycin was associated with a 7.5-fold increased SSI risk (P=.006). Microbiological analysis revealed a 30.6% prevalence of multidrug-resistant and ESBL-producing bacteria.\n\nConclusion:: Obesity and prolonged operative time are independent predictors of SSI. We recommend weight-based dosing, strict intraoperative re-dosing during prolonged procedures, and mandatory antimicrobial stewardship to mitigate risks associated with non-standard prophylaxis.",
