Vancomycin Powder

Object Surgical site infection (SSI) is a serious and costly complication of spinal surgery. There have been several conflicting reports on the use of intrawound vancomycin powder in decreasing SSI in spine surgery. The purpose of this study is to answer the question: “Does intrawound vancomycin powder reduce the rate of SSIs in spine surgery?” Methods A comprehensive search of multiple electronic databases and bibliographies was conducted to identify clinical studies that evaluated the rates of SSI with and without the use of intrawound vancomycin powder in spine surgery. Independent reviewers extracted data and graded the quality of each paper that met inclusion criteria. A random effects meta-analysis was then performed. Results The search identified 9 retrospective cohort studies (Level III evidence) and 1 randomized controlled trial (Level II evidence). There were 2574 cases and 106 infections in the control group (4.1%) and 2518 cases and 33 infections (1.3%) in the treatment group, yielding a pooled absolute risk reduction and relative risk reduction of 2.8% and 68%, respectively. The meta-analysis revealed the use of vancomycin powder to be protective in preventing SSI (relative risk = 0.34, 95% confidence interval 0.17–0.66, p = 0.021). The number needed to treat to prevent 1 SSI was 36. A subgroup analysis found that patients who had implants had a reduced risk of SSI with vancomycin powder (p = 0.023), compared with those who had noninstrumented spinal operations (p = 0.226). Conclusions This meta-analysis suggests that the use of vancomycin powder may be protective against SSI in open spinal surgery; however, the exact population in which it should be used is not clear. This benefit may be most appreciated in higher-risk populations or in facilities with a high baseline rate of infection.

BACKGROUND: Intrawound treatments have been reported to have favorable efficacy for preventing surgical site infection (SSI); however, the best strategy remains unknown. OBJECTIVE: The aim of this systematic review and network meta-analysis was to evaluate the efficacy of intrawound treatments to prevent SSI after spine surgery. STUDY DESIGN: A systematic review and network meta-analysis. METHODS: We searched the Cochrane Library, EMbase, PubMed, Chinese Science and Technology Periodical Database (VIP), China National Knowledge Infrastructure (CNKI), and Wanfang Data from the date of inception to March 2, 2020. The randomized controlled trials (RCTs) and cohort studies were identified and extracted by 2 reviewers independently. We performed a traditional pairwise meta-analysis to evaluate overall efficacy of intrawound treatments. Meanwhile, a network meta-analysis was performed to compare and rank the treatment efficacy using frequentist approach. RESULTS: Thirty-three publications (6 RCTs and 27 retrospective cohort studies) were included, involving 22,763 patients. For pairwise meta-analysis, the combined results showed that the intrawound treatment had a significantly lower SSI rate than the control group (CG) (odds ratio [OR] = 0.41; 95% confidence interval [CI], 0.31–0.55). For network meta-analysis, the treatment of vancomycin (VA) (OR = 0.53; 95% CI, 0.39-0.71), povidone-iodine (PI) (OR = 0.10; 95% CI, 0.04 - 0.23), and vancomycin + povidone-iodine (VA+PI) (OR = 0.25; 95% CI, 0.11-0.58) were found to be significantly more efficacious than CG on reduction of SSI rate. PI ranked first on reducing SSI, followed by PI+HP, VA+PI, gentamicin (GM), VA, and hydrogen peroxide (HP); CG ranked last. LIMITATIONS: Firstly, only 6 RCTs are included in this systematic review. Retrospective cohort studies tend to exaggerate the real results, although most of them are high-quality according to the Newcastle-Ottawa Quality Assessment Scale (NOQAS). More high-quality RCTs need to be included to obtain convincing conclusions. Secondly, the population of this study involves both adult and pediatric cohorts, patients with tumor, congenital disease, or degenerative disease. There is no subgroup analysis for ages and type of diseases, which might have influence on the overall pooled analysis. Thirdly, we define the application of saline solution and no intrawound treatment as the control group, which might ignore their heterogeneity. Fourthly, follow-up periods are variable and the sample size of HP is small. Finally, additional research is needed to compare the complications of different treatments and the benefits of various dosages. CONCLUSION: We found that VA and PI show promising results on reducing SSI. PI is recommended as the most efficacious intrawound treatment to prevent SSI after spine surgery.

Abstract BACKGROUND Surgical site infection (SSI) is a common complication following spinal surgery. Prevention is critical to maintaining safe patient care and reducing additional costs associated with treatment. OBJECTIVE To determine the efficacy of preoperative chlorhexidine (CHG) showers on SSI rates following fusion and nonfusion spine surgery. METHODS A mandatory preoperative CHG shower protocol was implemented at our institution in November 2013. A cohort comparison of 4266 consecutive patients assessed differences in SSI rates for the pre- and postimplementation periods. Subgroup analysis was performed on the type of spinal surgery (eg, fusion vs nonfusion). Data represent all spine surgeries performed between April 2012 and April 2016. RESULTS The overall mean SSI rate was 0.4%. There was no significant difference between the pre- (0.7%) and postimplementation periods (0.2%; P = .08). Subgroup analysis stratified by procedure type showed that the SSI rate for the nonfusion patients was significantly lower in the post- (0.1%) than the preimplementation group (0.7%; P = .02). There was no significant difference between SSI rates for the pre- (0.8%) and postimplementation groups (0.3%) for the fusion cohort (P = .21). In multivariate analysis, the implementation of preoperative CHG showers were associated with significantly decreased odds of SSI (odds ratio = 0.15, 95% confidence interval [0.03-0.55], P < .01). CONCLUSION This is the largest study investigating the efficacy of preoperative CHG showers on SSI following spinal surgery. In adjusted multivariate analysis, CHG showering was associated with a significant decrease in SSI following spinal surgery.

Objective This study aimed to systematically analyze the effectiveness and safety of the local application of vancomycin powder to prevent surgical site infection (SSI) after spinal surgeries and provide guidance for clinical practice. Methods Two researchers independently searched PubMed, Web of Science, Elsevier, and China National Knowledge Infrastructure using the MeSH terms “spinal surgery,” “vancomycin,” “local,” “topical,” “prophylactic,” “surgical site infection,” and “SSI” to identify studies published between January 2010 and January 2020 on the local application of vancomycin powder for preventing SSI after spinal surgeries. The outcome assessment indicators were analyzed using RevMan 5.3 software. Results Three randomized controlled trials, two prospective studies, and 26 retrospective studies were included in the current research. The results of the meta-analysis revealed significant differences between the vancomycin and control groups (non-vancomycin group) concerning the incidence of SSI (risk ratio = 0.39, 95% confidence interval = 0.28–0.55, Z = 5.46), indicating that local application of vancomycin powder can significantly reduce the incidence of SSI. Conclusion Local application of vancomycin powder is an effective and safe method to prevent SSI after spinal surgeries.

Abstract Background Patients with prolonged and intense neutrophilia after spinal surgery are at high risk of developing surgical site infection (SSI). To date, there is no standard method for the objective assessment of the intensity and duration of neutrophilia. Thus, this retrospective observational study aimed to test a new index (I-index), developed by combining the duration and intensity of neutrophilia, as a predictor of SSI. Methods I-index was calculated based on the postoperative neutrophil percentage. A total of 17 patients with SSI were enrolled as cases, and 51 patients without SSI were selected as controls. The groups were matched at a ratio of 1:3 by age, sex, and surgery type. The differences in the I-index were compared between the groups. Moreover, we checked the cumulative I-index (c-I-index), which we defined as the area under the neutrophil curve from postoperative day 1 until the first clinical manifestation of SSI in each case. Furthermore, a cutoff for SSI was defined using the receiver operating characteristic curve. Results The median I-index-7, I-index-14, and c-I-index were significantly higher in the SSI group than those in the control group. For a cutoff point of 42.1 of the I-index-7, the sensitivity and specificity were 0.706 and 0.882, respectively. For a cutoff point of 45.95 of the I-index-14, the sensitivity and specificity were 0.824 and 0.804, respectively. For a cutoff point of 45.95 of the c-I-index, the sensitivity and specificity were 0.824 and 0.804, respectively. Conclusion We devised a new indicator of infection, i.e., the I-Index and c-I-index, and confirmed its usefulness in predicting SSI.
