Surgical site infection reduction bundle in patients with gynecologic cancer undergoing colon surgery

Surgical site infections (SSIs) can lead to substantial morbidity, prolonged hospitalization, increased costs, and death in patients undergoing colorectal procedures. We sought to investigate the effect of using an SSI reduction bundle on the rate of SSIs in gynecologic cancer patients undergoing colon surgery.

We identified all gynecologic cancer patients who underwent colon resection at our institution from 2014 to 2016, during which time a service-wide SSI reduction bundle was introduced. The intervention included preoperative oral antibiotics with optional mechanical bowel preparation, skin preparation with antibacterial solution, and the use of a separate surgical closing tray. SSI rates were assessed within 30days post-surgery.

Of 233 identified patients, 115 had undergone colon surgery prior to (PRE) and 118 after (POST) the implementation of the intervention. A low anterior resection was the most common colon surgery in both cohorts. The incidence of SSI within 30days of surgery was 43/115 (37%) in the PRE and 14/118 (12%) in the POST cohorts (p≤0.001). Wound dehiscence was noted in 30/115 (26%) and 2/118 (2%) patients, respectively (p≤0.001). In patients whose operation took longer than 360min, 30-day SSI rates were 37% (28/76) and 12% (8/67), respectively (p≤0.001). In patients with an estimated blood loss >500cm³, SSI rates were 44% (27/62) and 15% (10/67), respectively (p≤0.001).

The implementation of an SSI reduction bundle was associated with a significant reduction in 30-day SSIs in these patients. The intervention remained effective in patients undergoing longer operations and in those with increased blood loss.
