Abstract


Background: Surgical site infections (SSI) are infections presents in any location along the surgical tract after a surgical procedure. Knowledge of predictive factors associated with SSI is important for planning remedial measures. Abdominal wall hernia repair is a common procedure in general surgery practice and knowing the predictors of SSI in these clean surgeries requiring placement of mesh is the aim of the present study.

Methods: In a hospital based longitudinal study the subjects were diagnosed cases of anterior abdominal wall hernias undergoing planned or emergency surgeries. Patients of either gender and age group of 18 to 80 years were included in the study. Patients undergoing laparoscopic hernia repair were excluded. The study factors were patient and the surgeon related factors like laboratory parameters, surgeon experience etc. The outcome was SSI assessed with up to 30 days post-operative follow up.

Results: Total 198 patients were enrolled with a mean age of 42.49±15.72 years and male preponderance. Overall SSI rate was 9.09% and in planned cases it was 7.07% and 50% in emergency cases. Pre-operative hospital stays of >5 days was the only patient factor associated with increased risk of SSI (p=0.0004) and operating surgeon’s experience was associated with increased risk if SSI i.e. cases operated by junior surgeons had a higher risk of SSI (p=0.013).

Conclusions: The only modifiable factor associated with SSI was pre-operative hospital stay of >5 days while high incidence of SSI with junior surgeons cannot be modified in a teaching institute.
