AbstractHbA1c testing provides average blood glucose control, an elevated result may be associated with adverse post-operative outcomes. Our objective was to evaluate the association between elevated pre-operative HbA1c and post-operative complications in patients undergoing major gynaecological oncology surgery. HbA1c was measured pre-operatively in 364 patients. We identified 65 (16%) patients at risk of developing diabetes with borderline HbA1c measurements.Patients with borderline HbA1c (42-47 mmol/mol) had almost double the incidence of infections compared to patients with normal HbA1c (15.8% vs. 6.5%, p=.038). There were significantly less infections between patients with a normal HbA1c (<42 mmol/mol) and those with an HbA1c of over 42 mmol/mol (6.5% vs. 22.8%, p<.05). There was an association between elevated HbA1c and infective complications especially in patients with a borderline HbA1c. It is suggested that knowing HbA1c status, intervention can be made to prevent post-operative infective complications and improve outcomes.Impact statementWhat is already known on this subject? Obesity is a common risk factor for gynaecological cancer and elevated HbA1c. Chronically elevated HbA1c may lower immunity. An association has been shown previously between elevated HbA1c and post-operative complications.Whatthe results of this study add? This study examined infective complications in patients undergoing gynaecological surgery; showing that patients with a borderline HbA1c (42-47 mmol/mol), especially those with a diagnosis of diabetes to be most at risk. This suggests that pre-operative HbA1c should be used routinely to guide care rather than diabetic status alone to prevent post-operative infections.Whatthe implicationsareof these findings for clinical practice and/or further research? More research needs to be carried out to find the optimal pre-operative HbA1c targets to reduce post-operative infection rates. Work needs to be done in conjunction with general practitioners to help patients to reduce their HbA1c prior to treatment.
