Key result
Preoperative prognostic nutritional index was significantly lower in patients who developed surgical site infection compared to controls (median 32 vs 36, p<0.001), with a PNI <35 predicting infection risk.
Why the study?
Does a low preoperative prognostic nutritional index (PNI) predict the development of surgical site infection in patients undergoing abdominal surgery?
Case-Control (n=514)
No
Does a low preoperative prognostic nutritional index (PNI) predict the development of surgical site infection in patients undergoing abdominal surgery?
Effect estimate: AUC 0.655 (95% CI 0.608-0.702)
Absolute Event Rate: 32% vs 36%
p-value: p=<0.001
Low preoperative prognostic nutritional index (PNI < 35) is a significant risk factor for the development of surgical site infections following abdominal surgery.

Hakan Balbaloĝlu (2024) conducted a case-control in Abdominal surgery (n=514). Preoperative prognostic nutritional index (PNI) vs. Patients without surgical site infection was evaluated on Development of surgical site infection (SSI) (AUC 0.655, 95% CI 0.608-0.702, p=<0.001). Preoperative prognostic nutritional index was significantly lower in patients who developed surgical site infection compared to controls (median 32 vs 36, p<0.001), with a PNI <35 predicting infection risk.
