# Procedural risk factors for deep and organ/space surgical site infection post-coronary artery bypass graft surgery

## TL;DR

This study explores how surgical techniques and dressings affect infection risks after heart surgery.

## Contribution

The study identifies specific procedural factors linked to higher infection risks after coronary artery bypass graft surgery.

## Key findings

- Bilateral internal mammary artery grafts increase infection odds.
- Negative pressure wound therapy is associated with higher infection rates.

## Abstract

In this study, we examined the impact of the number and type of arterial grafts, and surgical dressing type, on deep and organ/space surgical site infection following coronary artery bypass graft procedures. Bilateral internal mammary artery grafts and negative pressure wound therapy were associated with higher odds of infection.
