Introduction:
There is minimal literature regarding when dressing changes should be performed. We present the dressing change protocol adopted by our institution. The purpose of this study was to provide an update of our experience with this dressing change protocol over a 15-year period.
Methods:
Effective January 2005, we implemented our universal protocol of no dressing changes for five days after surgery. Reviewing a health system administrative database, all spine surgery cases involving instrumentation performed at our institution were captured. Surgical site infection (SSI) cases: superficial, deep, and organ space as defined by the Centers for Disease Control and Prevention (CDC), were identified by reviewing an infection control database. Fisher exact test was used to compare SSI rates in all instrumented fusion cases from January 1999 to December 2004 (prior to implementation of the dressing change protocol) to those from January 2005 to December 2013 (after the protocol was initiated).
Results:
A total of 8,631 instrumented spine fusions were performed at a single institution from 1999 to 2013. Overall, after instituting our universal no-dressing-change protocol, SSI rates for all cervical, thoracic, and lumbar instrumented cases combined decreased from 3.9% (97/2473) to 0.93% (57/6158) (p < .0001). The reduction in SSI rates was most significant for posterior cervical and posterior lumbar surgeries. After our dressing change protocol was implemented, we saw an improvement in SSI rates for posterior cervical instrumented cases from 3.2% (6/186) to 0.50% (4/815) (p = .0041). Posterior lumbar instrumented fusion SSI rates dropped from 5.5% (65/1179) to 1.1% (32/2890) (p < .0001).
Conclusion:
Dressing changes in the immediate postoperative period are not necessary. Applying a sterile dressing in the operating room may serve as a barrier to nosocomial pathogens during hospitalization. Our data suggest this dressing change protocol may lead to reduced SSI risk. Leaving the original postoperative surgical dressing intact is safe, simple, and cost-effective.
Insights
Delaying dressing changes after spine surgery significantly reduces surgical site infection (SSI) rates. Leaving the initial sterile dressing intact for five days is a safe, cost-effective method to prevent infections.
Area of Science:
- Surgical Infection Prevention
- Postoperative Care Protocols
- Spine Surgery Outcomes
Background:
- Limited literature exists on optimal timing for surgical dressing changes.
- Postoperative wound management is crucial for preventing surgical site infections (SSIs).
- Standardizing dressing change protocols can impact patient outcomes and healthcare costs.
Purpose of the Study:
- To evaluate the impact of a universal no-dressing-change protocol on SSI rates in spine surgery.
- To update institutional experience with a 15-year dataset on postoperative dressing changes.
- To determine the safety and efficacy of leaving initial surgical dressings intact.
Main Methods:
- Implemented a protocol of no dressing changes for five days post-surgery starting January 2005.
- Reviewed administrative and infection control databases for instrumented spine surgery cases (1999-2013).
- Compared SSI rates (superficial, deep, organ space) before and after protocol implementation using Fisher exact test.
Main Results:
- Overall SSI rates in instrumented spine fusions decreased from 3.9% to 0.93% after protocol initiation (p < .0001).
- Significant reductions observed in posterior cervical (3.2% to 0.50%) and posterior lumbar (5.5% to 1.1%) surgeries.
- The no-dressing-change protocol demonstrated a marked decrease in surgical site infections.
Conclusions:
- Immediate postoperative dressing changes are unnecessary for spine surgery.
- A sterile initial dressing acts as a barrier against nosocomial pathogens.
- The protocol of leaving the original surgical dressing intact is safe, simple, cost-effective, and reduces SSI risk.
