Background: To investigate abdominal hysterectomy surgical site infection (SSI) rates before and after implementation of an SSI care bundle.

Methods: An SSI bundle for abdominal hysterectomies was introduced in our hospital in April 2014 to reduce the SSI rate. The practices were divided into bundle elements around preoperative, intraoperative, and postoperative care. We conducted a retrospective cohort study around implementation of the SSI care bundle. Women were included if they underwent abdominal hysterectomy between 2012 and 2015. They were then divided into 2 study groups: prebundle and postbundle. The primary study outcome was SSI rate. The superficial SSI rate was the secondary outcome.

Results: The overall SSI rate was 6.18% in the prebundle group, with a median monthly SSI rate of 7.03%. After bundle implementation, the overall SSI rate declined to 2.51% (P = .02). The reduction remained significant after multivariate analysis (adjusted odds ratio 0.38; 95% confidence interval 0.15-0.88; P = .03) indicating a 62% reduction in SSI postbundle as compared to prebundle.When comparing rates based on infection classification, superficial SSIs declined significantly from 3.73% in the prebundle group to 0.90% in the postbundle group (P = 0.02). Patient demographics and pre-existing medical conditions were similar pre- and postbundle. Compliance with bundle elements was high.

Conclusions: A significant reduction in SSI rate in abdominal hysterectomies was seen following implementation of an infection prevention bundle.

Background: Prophylactic parenteral administration of antibiotics is strongly recommended to prevent surgical site infection (SSI). Cefoxitin is mainly administered intravenously in colorectal surgery. The current standard method for administering prophylactic antibiotics in adults is to administer a fixed dose quickly before skin incision.

Recent findings suggest that combining mechanical bowel preparation (MBP) and preoperative oral antibiotics (OAs) decreases the risk of incisional surgical site infections (iSSIs) in colorectal surgery; however, this finding remains controversial. This study examined the efficacy of OAs and MBP in colorectal surgery using propensity score matching (PSM). : Between January 2015 and December 2020, 559 patients with colorectal tumors underwent MBP followed by colorectal surgery.

To determine whether a closed dressing protocol reduces the surgical site infections (SSI) rate compared to conventional closing techniques. Patients who underwent lumbar spine surgery at two neurosurgical centers were retrospectively included from June 2015 to December 2019. Data on patients, general risk factors, and surgical risk factors for SSI were collected.

Background: Numerous studies have identified typical risk factors for surgical site infections (SSI) and fascial dehiscence (FD), but patients with gynecological cancer are often excluded. This study aimed to assess the key risk factors for SSI and FD in gynecological oncological patients undergoing median laparotomy.

Methods: We conducted a retrospective cohort study of patients who underwent median laparotomy for gynecological cancer between January 2017 and December 2020.

Introduction: Surgical site infection (SSI) is one of the most serious postoperative complications following instrumented spinal surgery. We previously reported the potential of continuous local antibiotic perfusion (CLAP) to retain implants for patients with SSI following instrumented spinal surgery. We conducted a retrospective multicenter study to elucidate the efficacy and limitations of CLAP for patients with SSI following instrumented spinal surgery.
