Background: Surgical site infections (SSI) are a substantial concern for cesarean deliveries in which a surgical site complication is most unwelcome for a mother with a new infant. Steps taken pre- and post-operatively to reduce the number of complications may be of substantial benefit clinically, economically, and psychologically.
Methods: A risk-based approach to incision management was developed and implemented for all cesarean deliveries at our institution. A number of incremental interventions for low-risk and high-risk patients including pre-operative skin preparations, standardized pre- and post-operative protocols, post-operative nanocrystalline silver anti-microbial barrier dressings, and incisional negative pressure wound therapy (NPWT) were implemented sequentially over a 5-y period. A systematic clinical chart review of 4,942 patients spanning all cesarean deliveries between 2007-2012 was performed to determine what effects the interventions had on the rate of SSI for cesarean deliveries.
Results: The percentage of SSI was reduced from 2.13% (2007) to 0.10% (2012) (p<0.0001). There were no substantial changes in the patient population risk factors over this time. As a result of the changes in incision management practice, a total of 92 cesarean post-operative SSIs were avoided: A total cost saving of nearly $5,000,000.
Conclusion: Applying a clinical algorithm for assessing the risk of surgical site complication and making recommendations on pre-operative and post-operative incision management can result in a substantial and sustainable reduction in cesarean SSI.
