The aim of this study was to assess the relationship between haemoglobin A1c (HbA1c) values and operative wound infection


During the period from 2013–2016, consecutive patients with type 2 diabetes were prospectively evaluated. Data were retrospectively analysed. All included patients were admitted for an elective surgical procedure, requiring the use of prosthetic graft in a groin wound. The patients were divided into two groups according to their preoperative HbA1c values. The main outcome was groin wound infection. The association between preoperative long-term glycoregulation and wound infection was evaluated, as well as the impact of postoperative glycaemic values, regardless of the level of HbA1c.


Of the 93 participating patients, wound infection occurred in 20 (21.5%). Wound infection occurred in 28.2% of patients with uncontrolled diabetes (HbA1c >7%) and 16.7% of patients with controlled diabetes (HbA1c <7%); however, the difference did not reach statistical significance (p=0.181). In regression modelling, operative time (p=0.042) was a significant predictor of wound infection, while patients' age (p=0.056) was on the borderline of statistical significance. Females had a higher probability for wound infection (odds ratio (OR): 1.739; 95% confidence interval (CI):0.483–6.265), but there was no statistical significance (p=0.397). Patients with elevated levels of HbA1c had a higher chance of wound infection compared with patients with controlled diabetes (OR: 2.243; 95% CI: 0.749–6.716), nevertheless, this was not statistically significant (p=0.149).


We found no statistically significant correlation between elevated values of preoperative HbA1c and postoperative groin wound infection.
