Surgical Site Infection Risk Based on Patient's Percent Body Fat

Purpose: To identify the risk of surgical site infection in a patient based on the percent body fat measured by bioelectrical impedance analysis (BIA).

Description

Waisbren et al correlated the risk of surgical site infection (SSI) with the percent body fat. This correlates better with the risk of infection than does the body mass index (BMI). The authors are from Brigham and Women's Hospital and Children's Hospital Boston.


Analysis: percent body fat by bioelectrical impedance analysis (BIA)

 

Percent Body Fat

Risk of Surgical Site Infection

20.1 to 25%

8.8%

25.1 to 30%

9.7%

30.1 to 35%

11.7%

35.1 to 40%

15.5%

40.1 to 45%

15.7%

45.1 to 50%

19.9%

 

The relationship between percent body fat and the risk of surgical site infection is somewhat linear. The relationship with body mass index and surgical site infection was highly variable.
