AbstractOBJECTIVES:Our goal was to determine the optimal timing and choice of surgical antimicrobial prophylaxis (SAP) in patients having cardiac surgery.METHODS:The setting was the Swiss surgical site infection (SSI) national surveillance system with a follow-up rate of >94%. Participants were patients from 14 hospitals who had cardiac surgery from 2009 to 2017 with clean wounds, SAP with cefuroxime, cefazolin or a vancomycin/cefuroxime combination and timing of SAP within 120 min before the incision. Exposures were SAP timing and agents; the main outcome was the incidence of SSI. We fitted generalized additive and mixed-effects generalized linear models to describe effects predicting SSIs.RESULTS:A total of 21 007 patients were enrolled with an SSI incidence of 5.5%. Administration of SAP within 30 min before the incision was significantly associated with decreased deep/organ space SSI [adjusted odds ratio (OR) 0.73, 95% confidence interval (CI) 0.54–0.98; P = 0.035] compared to administration of SAP 60–120 min before the incision. Cefazolin (adjusted OR 0.64, 95% CI 0.49–0.84; P = 0.001) but not vancomycin/cefuroxime combination (adjusted OR 1.05, 95% CI 0.82–1.34; P = 0.689) was significantly associated with a lower risk of overall SSI compared to cefuroxime alone. Nevertheless, there were no statistically significant differences between the SAP agents and the risk of deep/organ space SSI.CONCLUSIONS:The results from this large prospective study provide substantial arguments that administration of SAP close to the time of the incision is more effective than earlier administration before cardiac surgery, making compliance with SAP administration easier. The choice of SAP appears to play a significant role in the prevention of all SSIs, even after adjusting for confounding variables.

Objective.To evaluate the effectiveness of an intervention based on training and the use of a protocol with an automatic stop of antimicrobial prophylaxis to improve hospital compliance with surgical antibiotic prophylaxis guidelines.Design.An interventional study with a before-after trial was conducted in 3 stages: a 3-year initial stage (January 1999 to December 2001), during which a descriptive-prospective survey was performed to evaluate surgical antimicrobial prophylaxis and surgical site infections; a 6-month second stage (January to June 2002), during which an educational intervention was performed regarding the routine use of a surgical antimicrobial prophylaxis request form that included an automatic stop of prophylaxis (the “automatic-stop prophylaxis form”); and a 3-year final stage (July 2002 to June 2005), during which a descriptive-prospective survey of surgical antimicrobial prophylaxis and surgical site infections was again performed.Setting.An 88-bed teaching hospital in Entre Ríos, Argentina.Patients.A total of 3,496 patients who underwent surgery were included in the first stage of the study and 3,982 were included in the final stage.Results.Comparison of the first stage of the study with the final stage revealed that antimicrobial prophylaxis was given at the appropriate time to 55% and 88% of patients, respectively (relative risk [RR], 0.27 [95% confidence interval {CI}, 0.25-0.30]; P < .01); the antimicrobial regimen was adequate in 74% and 87% of patients, respectively (RR, 0.50 [95% CI, 0.45-0.55]; P < .01); duration of the prophylaxis was adequate in 44% and 55% of patients, respectively (RR, 0.80 [95% CI, 0.77-0.84]; P < .01); and the surgical site infection rates were 3.2% and 1.9%, respectively (RR, 0.59 [95% CI, 0.44-0.79]; P < .01). Antimicrobial expenditure was US$10,678.66 per 1,000 patient-days during the first stage and US$7,686.05 per 1,000 patient-days during the final stage (RR, 0.87 [95% CI, 0.86-0.89]; P<.01).Conclusion.The intervention based on training and application of a protocol with an automatic stop of prophylaxis favored compliance with the hospital's current surgical antibiotic prophylaxis guidelines before the intervention, achieving significant reductions of surgical site infection rates and substantial savings for the healthcare system.

Background: Surgical site infection (SSI) after cerebrospinal fluids (CSF) shunt surgery is thought to be acquired intraoperatively. Biomaterial-associated infection can present up to 1 year after surgery, but many national systems have shortened follow-up to 90 days. We compared 3- versus 12-month follow-up periods to determine the nature of case ascertainment in the 2 periods. Methods: Participants of any age with placement of an internal CSF shunt or revision surgical manipulation of an existing internal shunt identified in the Canadian Nosocomial Infection Surveillance Program (CNISP) participating hospitals between 2006 and 2018 were eligible. We excluded patients with external shunting devices or culture-positive CSF at the time of surgery. Patients were followed for 12 months after surgery for the primary outcome of a CSF infection with a positive CSF culture by review of laboratory and health records. Patients were categorized as adult (aged ≥18 years) or pediatric (aged < 18 years). The infection rate was expressed as the number of CSF shunt-associated infections divided by the number of shunt surgeries per 100 procedures. Results: In total, 325 patients (53% female) met inclusion criteria in 14 hospitals from 7 provinces were identified. Overall, 46.1% of surgeries were shunt revisions and 90.3% of shunts were ventriculoperitoneal. For pediatric patients, the median age was 0.7 years (IQR, 0.2–7.0). For adult patients, the median age was 47.9 years (IQR, 29.6–64.6). The SSI rates per 100 procedures were 3.69 for adults and 3.65 for pediatrics. The overall SSI rates per 100 procedures at 3 and 12 months were 2.74 (n = 265) and 3.48 (n = 323), respectively. By 3 months (90 days), 82% of infection cases were identified (Fig. 1). The median time from procedure to SSI detection was 30 days (IQR, 10–65). No difference was found in the microbiology of the shunt infections at 3- and 12-month follow-ups. The most common pathogens were coagulase-negative Staphylococcus (43.6 %), followed by S. aureus (24.8 %) and Propionibacterium spp (6.5 %). No differences in age distribution, gender, surgery type (new or revision), shunt type, or infecting organisms were observed when 3- and 12-month periods were compared. Conclusions: CSF-SSI surveillance for 3 versus 12 months would capture 82.0% (95% CI, 77.5–86.0) of cases, with no significant differences in the patient characteristics, surgery types, or pathogens. A 3-month follow-up can reduce resources and allow for more timely reporting of infection rates.Funding: NoneDisclosures: None

Study Design: A retrospective study. Objectives: To investigate the incidence, management and outcome of delayed deep surgical site infection (SSI) after the spinal deformity surgery. Methods: This study reviewed 5044 consecutive patients who underwent spinal deformity corrective surgery and had been followed over 2 years. Delayed deep SSI were defined as infection involving fascia and muscle and occurring >3 months after the initial procedure. An attempt to retain the implant were initially made for all patients. If the infection failed to be eradicated, the implant removal should be put off until solid fusion was confirmed, usually more than 2 years after the initial surgery. Radiographic data at latest follow-up were compared versus that before implant removal. Results: With an average follow-up of 5.3 years, 56 (1.1%) patients were diagnosed as delayed deep SSI. Seven (12.5%) patients successfully retained instrumentation and there were no signs of recurrence during follow-up (average 3.4 years). The remaining patients, because of persistent or recurrent infection, underwent implant removal 2 years or beyond after the primary surgery, and solid fusion was detected in any case. However, at a minimum 1-year follow-up (average 3.9 years), an average loss of 9° in the thoracic curve and 8° in the thoracolumbar/lumbar curves was still observed. Conclusions: Delayed deep SSI was rare after spinal deformity surgery. To eradicate infection, complete removal of implant may be required in the majority of delayed SSI. Surgeons must be aware of high likelihood of deformity progression after implant removal, despite radiographic solid fusion.

Our report details an implant-associated outbreak of surgical site infections related to the adverse effects of treatment for hepatitis C virus infection administered to surgeon X. During the 12-month period of this outbreak, 14 (9.5%) of 148 of surgeon X's patients developed a surgical site infection, a rate of SSI that was 8-fold higher than the rate during the 14-month baseline period or the 14-month follow-up period (P = .001), and higher than the rate among peer surgeons (P = .02).
