WP1.8 - No, we can’t repair your hernia: An audit to assess pre-operative optimisation for umbilical hernia repair

Abstract Aims The European Hernia Association recently published guidelines which clearly outline the importance of pre-operative optimisation for those undergoing elective umbilical/epigastric hernias. The main factors of importance are: smoking cessation and BMI <35. This audit aimed to identify if we are adequately optimising our patients. Methods We retrospectively evaluated all elective umbilical hernia repairs from 1st January 2022- 31st December 2022 within a district general hospital setting. Clinic letters and pre-operative records were used to ascertain smoking status, BMI and diabetic control (HbA1c). Results 60 umbilical hernias were performed in our district general hospital setting from 1st January 2022- 31st December 2022. Of these patients, 12% (N=7) were known smokers and 13% (N=8) had a BMI of over 35 documented. Additionally, only in 15 cases, was there clear documentation of the patient smoking status. Out of these patients, 9 were subsequently found to be non-smokers and 6 remained smokers despite being given smoking cessation advice. Furthermore, in 10% (N=6) of these cases, there was poor diabetic control (HbA1c > 48), which was not addressed in clinic pre-operatively. Conclusion Patient factors such as smoking, obesity and diabetic control have been shown to significantly increase the rate of post-operative wound infections and complications. Patients are not being adequately optimised for elective procedures which puts them at increased risk of complications and increases the burden on limited NHS resources.
