Abdominal Subcutaneous Fat is Predictor of Surgical Site Infection, Study Shows

May 31, 2011

A study published online in the Journal of the American College of Surgeons on May 20, 2011 reveals that abdominal subcutaneous fat is an independent predictor of superficial incisional surgical site infections (SSI) after midline laparotomy procedures.

The researchers’ hypothesis was that morphometric measures of midline subcutaneous fat would be associated with an increased risk of SSI and would in fact be a better SSI predictor than conventional measures of obesity.

SSIs were observed in 12.5% of the study population which had 82 subjects. Patients with increased subcutaneous fat had significantly greater odds of experiencing a superficial incisional SSI.

The research also showed that when comparing the two model variables (body mass index (BMI) versus subcutaneous fat), subcutaneous fat was a significantly improved model predictor of superficial incisional SSI.
