Abstract Background The Prevention of Arrhythmia Device Infection Trial (PADIT) investigated whether intensification of perioperative prophylaxis could prevent cardiac implantable electronic device (CIED) infections. Compared with a single dose of cefazolin, the peri-operative administration of cefazolin, vancomycin, bacitracin and cephalexin did not significantly decrease the risk of infection. Our objective is to compare the microbiology of infections between study arms in PADIT. Methods Post-hoc analysis. Differences between study arms in the microbiology of infections were assessed at the level of individual patients and at the level of microorganisms using the Fisher’s exact test. Results Overall, 209 microorganisms were reported from 177 patients. The most common microorganisms were coagulase-negative staphylococci (CoNS, 82/209; 39.2%) and S. aureus (75/209; 35.9%). There was a significantly lower proportion of CoNS in the incremental arm compared with the standard arm (30.1% vs. 46.6%, p=0.04). However, there was no significant difference between study arms in the frequency of recovery of other microorganisms. In terms of antimicrobial susceptibility, 26.5% of microorganisms were resistant to cefazolin. CoNS were more likely to be cefazolin-resistant in the incremental arm (52.2% vs. 26.8%, respectively; p=0.05). However, there was no difference between study arms in terms of infections in which the main pathogen was sensitive to cefazolin (77.8% vs. 64.3%; p=0.10) or vancomycin (90.8% vs. 90.2%; p=0.90). Conclusions Intensification of the prophylaxis led to significant changes in the microbiology of infections, despite the absence of a decrease in the overall risk of infections. These findings provide important insight on the physiopathology of CIED infections.

Abstract Background Infection is a major complication following cerebral spinal fluid (CSF) diversion procedures for hydrocephalus. However, pediatric risk factors for surgical site infection (SSI) are currently not well defined. Because a SSI prevention bundle is increasingly introduced, the purpose of this study was to evaluate risk factors associated with SSIs following CSF diversion surgeries following a SSI bundle at a single quaternary care pediatric hospital. Methods We performed a retrospective cohort study of patients undergoing CSF diversion procedures from 2017 to 2019. SSIs were identified prospectively through continuous surveillance. We performed unadjusted logistic regression analyses and univariate analyses to determine an association between SSIs and patient demographics, comorbidities and perioperative factors to identify independent risk factors for SSI. Results We identified a total of 558 CSF diversion procedures with an overall SSI rate of 3.4%. The SSI rates for shunt, external ventricular drain (EVD) placement, and endoscopic third ventriculostomy (ETV) were 4.3, 6.9 and 0%, respectively. Among 323 shunt operations, receipt of clindamycin as perioperative prophylaxis and presence of cardiac disease were significantly associated with SSI (O.R. 4.99, 95% C.I. 1.27–19.70, p = 0.02 for the former, and O.R. 7.19, 95% C.I. 1.35–38.35, p = 0.02 for the latter). No risk factors for SSI were identified among 72 EVD procedures. Conclusion We identified receipt of clindamycin as perioperative prophylaxis and the presence of cardiac disease as risk factors for SSI in shunt procedures. Cefazolin is recommended as a standard antibiotic for perioperative prophylaxis. Knowing that unsubstantiated beta-lactam allergy label is a significant medical problem, efforts should be made to clarify beta-lactam allergy status to maximize the number of patients who can receive cefazolin for prophylaxis before shunt placement. Further research is needed to elucidate the mechanism by which cardiac disease may increase SSI risk after shunt procedures.

Introduction: Laparoscopic cholecystectomy is considered as the gold standard treatment for gallstone disease. There has remained a controversy on use of peri operative prophylactic antibiotics during laparoscopic cholecystectomy in reducing perioperative prophylaxis surgical site infections. Various studies has been done to evaluate whether single dose/ three doses or multiple doses are needed to decrease the incidence of surgical site infections. The objective of this study was to identify the incidence of postoperative surgical site infections with three doses of perioperative antibiotics after laparoscopic cholecystectomy. Materials and Methods: This is a retrospective observational study conducted at a private hospital from November 2017 to March 2020. All the patients received three doses of ceftriaxone 1 gram within the first 24 hours of surgery. The incidence of surgical site infection was noted. Results: A total of 449 patients who fulfilled the inclusion criteria were studied. The age ranged from 16 to 88 years. Male to female ratio was 1:4. Seven cases (1.55%) developed postoperative surgical site infections. Conclusion: Three doses of perioperative antibiotics are recommended in laparoscopic cholecystectomy to prevent postoperative surgical site infections.

Abstract Objectives Surgical antibiotic prophylaxis (SAP) represents a major indication of antibiotic consumption worldwide. The present study aims to report the results of an enabling, long-term AMS intervention conducted between 2013 and 2019 on an Italian University Hospital performing more than 40.000 surgical interventions per year. Methods SAP inappropriateness was defined according to the ASHP guidelines and divided in four main categories: indication, selection and dosing, duration, timing. Between 2013 and 2019, we conducted a continuative AMS intervention over 14 surgical departments that included enablement, review of selected clinical records and feedback. Results We collected a total of 789 SAP prescribed to 735 patients (mean age 56.7 ± 17.8y). Overall, guideline adherence improved from 36.6% (n = 149) at baseline to 57.9% (n = 221) post-intervention (P <  0.0001). A significant improvement (P <  0.001) was also detected for each category: indication (from 58.5 to 93.2%), selection and dosing (from 58.5 to 80.6%), timing (from 92.4 to 97.6%), duration (from 71 to 80.1%). Conclusions Though results cannot be generalized to all hospital populations, enabling AMS interventions may be effective in establishing a sustained improvement in SAP appropriateness rates. Once identified the main causes of SAP inappropriateness, tailored AMS interventions for each department may be beneficial. Further studies are needed to evaluate specific outcomes as incidence of surgical site infections and antimicrobial resistance.

Abstract Implementation of a perioperative allergy and antibiotic assessment tool in patients with reported beta-lactam allergy resulted in a pronounced and sustained increase in perioperative cefazolin use. This intervention could result in improved efficiencies surrounding perioperative antibiotic administration and possible reductions in surgical site infection rates.
