Does Intrawound Vancomycin Decrease Postoperative Surgical Site Infection in Spine Surgery: A Retrospective...

Area of Science:

• Orthopedic Surgery
• Infectious Disease Control
• Surgical Outcomes Research

Background:

• Surgical site infections (SSI) are a significant concern, comprising 22% of healthcare-associated infections.
• The efficacy of intrawound Vancomycin for preventing SSI in spine surgery remains inadequately studied.

Purpose of the Study:

• To determine the overall postoperative SSI rate in patients undergoing spine surgery.
• To evaluate the impact of intrawound Vancomycin on reducing postoperative infection rates.

Main Methods:

• Retrospective case-control study of 19,081 spine surgeries (2003-2013).
• Cases with verified SSI were matched 1:1 with controls based on demographics and surgery date.
• Analysis included patient factors, surgical details, and intrawound Vancomycin administration.

Main Results:

• An overall SSI rate of 1.7% (316 cases) was identified.
• Intrawound Vancomycin use was associated with a reduced odds ratio (OR) for SSI (0.44, P=0.019).
• Higher BMI (>30) was linked to an increased OR for SSI (1.63, P=0.03).

Conclusions:

• Intrawound Vancomycin administration demonstrated a significant association with reduced postoperative SSI in spine surgery.
• Further research is necessary to establish optimal dosing, application methods, and long-term safety profiles.
