Epidemiology, clinical profile, and outcomes of CSF-diversion catheter-related infections - Prospective cohort study results from a single quaternary neurosurgery referral centre. Indian J Med Microbiol 2024; 48:100534. [PMID: 38367805 DOI: 10.1016/j.ijmmb.2024.100534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 01/24/2024] [Accepted: 01/25/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND Device-associated CNS infections is a major subgroup of healthcare associated CNS infections. Healthcare-associated ventriculitis or meningitis differs considerably from community-acquired meningitis in its epidemiology, pathogenesis, clinical presentation and management. OBJECTIVES This study aimed to identify the infection rates, the associated risk factors, and outcomes of these life-threatening infections. METHODS This was a 2-year single center prospective cohort study. Patient's clinical data, laboratory parameters, treatment and their outcomes were collected using data collection tool, and device days were collected from the hospital information system (HIS). Patients were categorised using IDSA criteria as contamination or colonisation or infection. Cox regression model was used for multivariate analysis to estimate hazard risk. RESULTS A total of 578 CSF diversion catheters were inserted in 472 patients. The average rate for EVD and LD infection were 11.12 and 11.86 per 1000 device days respectively. The average infection rates for VP and LP shunts were 6% and 5.2% per procedure, respectively. The commonest etiological agent causing CSF diversion catheter-related infection (CDRI) was Klebsiella pneumoniae (n = 14, 40%). The risk factors which were independently associated with increased infection risk by cox regression analysis were drain insertion ≥7 days [HR:11.73, p -0.03], posterior approach of EVD insertion (occipital) [HR:9.53, p - 0.01], pre-OP ASA score>3 [HR:8.28, p - 0.013] presence of EVD/LD leak [HR: 17.24, p < 0.0001], male gender [HR:2.05, p-0.05] and presence of associated peri-operative scalp infections [HR:3.531, p-0.005]. Shift to narrow spectrum surgical prophylactic antibiotic [Coefficient: -1.284, p-0.03] and reduction in CSF sampling frequency [Coefficient: -1.741, p-0.02] were found to be negatively associated with CDRI. CONCLUSIONS The study demonstrated drain insertion ≥7 days, posterior approach of EVD insertion, presence of EVD/LD leak, male gender and presence of associated peri-operative scalp skin and soft tissue infections were associated with increased risk of infection.

Abstract
INTRODUCTION In the present study, neonates presenting with neural tube defects (NTDs) and undergoing observation within the confines of the neonatal intensive care unit (NICU) were subjected to a comprehensive assessment encompassing concurrent morbidities, clinical manifestations, laboratory parameters, and instituted interventions. MATERIALS AND METHODS A retrospective examination was conducted on the medical records of 135 neonates diagnosed with congenital NTD within the temporal span from 2008 to 2018. The study cohort was drawn from the NICU of the Health Sciences University Erzurum Regional and Research Hospital Health Practice and Research Center. DISCUSSION The current investigation encompasses a retrospective analysis of 135 patients diagnosed with NTD who received treatment at the NICU between the years 2008 and 2018. Among these, 74 individuals (54.2%) were male, while 61 (45.8%) were female. Maternal ages ranged from 17 to 46 years, with variations in the number of pregnancies, ranging from 1 to 10. Notably, 71 cases (52.6%) were delivered through normal spontaneous delivery, whereas 64 cases (47.4%) underwent cesarean section. The familial context revealed that five patients (3.6%) had siblings with a history of NTD, while no instances were noted where mothers had received antenatal folic acid support. Birth weights of the neonates ranged from 1425 to 4500 grams. Consanguinity was identified in the parental relationships of 17 cases (12.6%). The average diameter of the neural tube sac was determined to be 4.83 ± 1.94 cm (1-12 cm). Predominantly, the lumbosacral region emerged as the most common site of NTD, with meningomyelocele being the prevailing NTD type. Hydrocephalus coexisted in 67 cases, and notably, 44 instances exhibited the development of hydrocephalus post-sac operation. Eight patients were deemed inoperable, and the initial surgery transpired at an average age of 4.3 ± 2.6 (0-17) days. Flap closure constituted 32 of the surgical interventions, while primary closure was implemented in 95 cases. Neurogenic bladder antedated the operation in 14 patients, and 12 individuals developed neurogenic bladder postoperatively. Ventriculoperitoneal shunt placement was warranted in 47 patients. The average duration of hospitalization was 22.5 ± 14.4 days. Regrettably, three patients died due to complications and infections during their hospital stay. RESULT NTD represents a significant cohort of pathologies necessitating a comprehensive and interdisciplinary management strategy. These anomalies are characterized by elevated morbidity and mortality rates, not only exerting substantial financial strains on societal, familial, and state healthcare resources but also inflicting profound emotional distress upon affected families. Crucially, periconceptional strategies emphasizing balanced nutrition coupled with targeted multivitamin and mineral supplementation, particularly the inclusion of folic acid, assume paramount importance in the prophylaxis of this debilitating condition.

A meta‐analysis examined the effect of intrawound vancomycin on surgical site wound infections in non‐spinal neurosurgical operation. Int Wound J 2022; 20:1584-1590. [PMID: 36424840 PMCID: PMC10088818 DOI: 10.1111/iwj.14014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 10/24/2022] [Accepted: 10/24/2022] [Indexed: 11/26/2022] Open
Abstract
To assess the impact of intrawound vancomycin on surgical site wound infections in non-spinal neurosurgical operations, we conducted a meta-analysis. A thorough review of the literature up to September 2022 showed that 4286 participants had a non-spinal neurosurgical operation at the start of the investigations; 1975 of them used intrawound vancomycin, while 2311 were control. Using dichotomous or contentious methods and a random or fixed-effect model, odds ratios (OR) and mean difference (MD) with 95% confidence intervals (CIs) were estimated to evaluate the impact of intrawound vancomycin on surgical site wound infections in non-spinal neurosurgical operation. The intrawound vancomycin had significantly lower surgical site wound infections (OR, 0.28; 95% CI, 0.19-0.40; P < .001) with low heterogeneity (I2 = 32%) compared with the control in non-spinal neurosurgical operation. The intrawound vancomycin had significantly lower surgical site wound infections compared with control in non-spinal neurosurgical operation. The low sample size of 2 out of 13 researches in the meta-analysis calls for care when analysing the results.

Abstract
INTRODUCTION The ventriculoperitoneal shunt is one of the most commonly performed neurosurgical procedures. One of the avoidable complications of shunt surgery is shunt infection. This PRISMA-compliant meta-analysis analysed the effectiveness of topical and/or intraventricular antibiotics in preventing shunt infections in patients undergoing shunt surgery. METHODS Four databases were searched from inception to 30th June 2021. Only original articles comparing the rate of shunt infection with and without antibiotics were included. Random-effects meta-analysis was used to compare the effect of the use of antibiotics in preventing infection and subgroup analysis for finding differences in various antibiotics. RESULTS The rate of shunt infection was 2.24% (53 out of 2362) in the topical antibiotic group in comparison to 5.24% (145 out of 2764) in the control group (p = 0.008). Subgroup analysis revealed that there is no significant difference between the antibiotics used. CONCLUSIONS Our meta-analysis found that the risk of shunt infection is significantly reduced with the use of topical and intraventricular antibiotics without any serious adverse effect. No side effects of topical or intraventricular antibiotics were reported in the included studies. Further prospective studies are required to establish the safety and optimal dosage of topical antibiotics for them to be used routinely in neurosurgical practice. They can be used in patients at high risk of developing shunt infections till such studies are available.

Abstract
OBJECTIVE To identify the best protective interventions against shunt infection and, hence, to find an appropriate protocol assumed to be associated with reduction of infection rates. METHODS A combined prospective-retrospective cohort study was conducted over a period of 5 years in 3 referral hospitals. Twelve interventions against infection practiced by blinded surgeons during ventriculoperitoneal shunt operations were surveyed and their association with the outcome of interest (i.e., shunt infection) was tested. Interventions proved to be associated with the outcome entered a multivariate logistic regression to identify the protective interventions. RESULTS Among a total of 392 cases, shunt infection was diagnosed in 11.5% with a median onset of 55 days. Patients' demographics, etiology of hydrocephalus, shunt-related factors, and type of preoperative antibiotics were not associated with shunt infection. Two-thirds of infected shunts revealed Staphylococcus species. Among the tested interventions, double-gloving and device and wound irrigation using vancomycin solution and the use of incision adhesive drapes proved to exhibit a significant protective effect against shunt infection, whereas operative time <40 minutes revealed a marginal protective benefit. CONCLUSIONS Shunt infection is a significant complication that occurs early during the first 2 months after surgery. According to the study findings, an appropriate protocol against shunt infection is assumed to be composed of double-gloving, device and wound irrigation using vancomycin solution, and the use of incision adhesive drapes. Reduced operative time had a beneficial effect against shunt infection, although it was of marginal significance in the current study.

Abstract
OBJECTIVE Myelomeningocele (MMC) is frequently complicated by symptomatic hydrocephalus, necessitating early permanent CSF diversion and revision surgeries. Shunt infections are a common cause of shunt malfunction. This study aims to characterize long-term shunt-related outcomes of patients undergoing MMC closure. METHODS A total of 170 patients undergoing MMC closure between the years of 1995 and 2017 were identified from a retrospective review of a prospectively populated surgical database at the Children's Hospital of Pittsburgh. Patients who underwent MMC closure and required ventriculoperitoneal (VP) shunt insertion met criteria and were included in the primary study analysis. Analysis with a Fisher exact test was performed for categorical variables, and Mann-Whitney U-tests were utilized for numerical data. RESULTS Of the 158 total patients undergoing MMC closure and meeting inclusion criteria, 137 (87%) required VP shunt insertion. These 137 patients demonstrated a shunt revision rate of 21.1% per person-year and a shunt infection rate of 2.1% per person-year over a mean follow-up of 10.8 years. Patients had a mean of 3.4 ± 0.6 shunt surgeries prior to their first infection. Patients undergoing immediate shunt removal, external ventricular drain placement, or shunt replacement after clearing the infection had lower rates of subsequent infections than patients who initially were managed with shunt externalization (p < 0.001). Placement of a shunt at the time of MMC closure was not found to be a risk factor for infection. Of patients with initial shunt placement after the implementation of the Hydrocephalus Clinical Research Network protocol in 2011, the authors' institution has had a shunt infection rate of 4.2% per person-year and a revision rate of 35.7% per person-year. CONCLUSIONS This study describes long-term outcomes of shunted MMC patients and factors associated with shunt infections. Most patients underwent multiple revisions prior to the first shunt infection. Shunt externalization may be ineffective at clearing the infection and should be avoided in favor of early shunt removal and external ventricular drainage, followed by shunt replacement once infection is demonstrated to have cleared.

Abstract
Background The need for external cerebrospinal fluid (CSF) drains in aneurysmal subarachnoid haemorrhage (aSAH) patients is common and might lead to additional complications. Objective A relation between the presence of an external CSF drain and complication risk is investigated. Methods A prospective complication registry was analysed retrospectively. We included all adult aSAH patients admitted to our academic hospital between January 2016 and January 2018, treated with an external CSF drain. Demographic data, type of external drain used, the severity of the aSAH and complications, up to 30 days after drain placement, were registered. Complications were divided into (1) complications with a direct relation to the external CSF drain and (2) complications that could not be directly related to the use of an external CSF drain referred to as medical complications Results One hundred and forty drains were implanted in 100 aSAH patients. In total, 112 complications occurred in 59 patients. Thirty-six complications were drain related and 76 were medical complications. The most common complication was infection (n = 34). Drain dislodgement occurred 16 times, followed by meningitis (n = 11) and occlusion (n = 9). A Poisson model showed that the mean number of complications raised by 2.9% for each additional day of drainage (95% CI: 0.6–5.3% p = 0.01). Conclusion Complications are common in patients with aneurysmal subarachnoid haemorrhage of which 32% are drain-related. A correlation is present between drainage period and the number of complications. Therefore, reducing drainage period could be a target for further improvement of care.

Ventriculoperitoneal shunt infection rates using a standard surgical technique, including topical and intraventricular vancomycin: the Children's Hospital Oakland experience.

Abstract
OBJECTIVE Ventriculoperitoneal (VP) shunt infections are common complications after shunt operations. Despite the use of intravenous antibiotics, the incidence of infections remains high. Though antibiotic-impregnated catheters (AICs) are commonly used, another method of infection prophylaxis is the use of intraventricular (IVT) antibiotics. The authors describe their single-institution experience with a standard shunt protocol utilizing prophylactic IVT and topical vancomycin administration and report the incidence of pediatric shunt infections. METHODS Three hundred two patients undergoing VP shunt procedures with IVT and topical vancomycin between 2006 and 2016 were included. Patients were excluded if their age at surgery was greater than 18 years. Shunt operations were performed at a single institution following a standard shunt protocol implementing IVT and topical vancomycin. No AICs were used. Clinical data were retrospectively collected from the electronic health records. RESULTS Over the 11-year study period, 593 VP shunt operations were performed with IVT and topical vancomycin, and a total of 19 infections occurred (incidence 3.2% per procedure). The majority of infections (n = 10, 52.6%) were caused by Staphylococcus epidermidis. The median time to shunt infection was 3.7 weeks. On multivariate analysis, the presence of a CSF leak (OR 31.5 [95% CI 8.8-112.6]) and age less than 6 months (OR 3.6 [95% CI 1.2-10.7]) were statistically significantly associated with the development of a shunt infection. A post hoc analysis comparing infection rates after procedures that adhered to the shunt protocol and those that did not administer IVT and topical vancomycin, plus historical controls, revealed a difference in infection rates (3.2% vs 6.9%, p = 0.03). CONCLUSIONS The use of a standardized shunt operation technique that includes IVT and topical vancomycin is associated with a total shunt infection incidence of 3.2% per procedure, which compares favorably with the reported rates of shunt infection in the literature. The majority of infections occurred within 2 months of surgery and the most common causative organism was S. epidermidis. Young age (< 6 months) at the time of surgery and the presence of a postoperative CSF leak were statistically significantly associated with postoperative shunt infection on multivariate analysis. The results are hypothesis generating, and the authors propose that IVT and topical administration of vancomycin as part of a standardized shunt operation protocol may be an appropriate option for preventing pediatric shunt infections.

Abstract
Hydrocephalus is among the most common pediatric conditions treated by neurosurgeons. An antibiotic-impregnated shunt (AIS) was designed to reduce the rate of shunt infections. The objective of this systematic review and meta-analysis was to assess the efficiency of AIS in reducing the rate of shunt infection compared with standard shunts (SSs). A systematic search of PubMed, EMBASE, Medline, Cochrane Library, TRIP Database, CINAHL and Google Scholar databases was performed. Eligible studies included observational studies and randomized controlled trials (RCT) that compared the effects of AIS and SS for preventing shunt infections in pediatric patients. Twelve observational studies and one RCT conducted from January 2005 through October 2019 involving 7,952 pediatric patients were included in the analysis. The use of AIS significantly decreased the risk of CRI [risk ratio (RR) 0.42; 95% confidence interval: 0.33 to 0.53; P<0.00001] with no statistical heterogeneity across the included studies (I2=42%). This analysis demonstrates that the use of AIS significantly reduces the risk of shunt infection in pediatric patients.

Abstract
PURPOSE Posthaemorrhagic ventricular dilatation in preterm infants is primarily treated using temporising measures, of which the placement of a ventricular access device (VAD) is one option. Permanent shunt dependency rates are high, though vary widely. In order to improve the treatment burden and lower shunt dependency rates, we implemented several changes over the years. One of these changes involves the setting of the surgery from general anaesthesia in the OR to local anaesthesia in bed at the neonatal intensive care unit (NICU), which may seem counterintuitive to many. In this article, we describe our surgical technique and present the results of this regimen and compare it to our previous techniques. METHODS Retrospective study of a consecutive series of 37 neonates with posthaemorrhagic ventricular dilatation (PHVD) treated using a VAD, with a cohort I (n = 13) treated from 2004 to 2008 under general anaesthesia in the OR, cohort II (n = 11) treated from 2009 to 2013 under general anaesthesia in the NICU and cohort III (n = 13) treated from December 2013 to December 2017 under local anaesthesia on the NICU. RESULTS The overall infection rate was 14%; the VAD revision rate was 22% and did not differ significantly between the cohorts. Procedures under local anaesthesia never required conversion to general anaesthesia and were well tolerated. After an average of 33 tapping days, 38% of the neonates received a permanent ventriculoperitoneal (VP) shunt. The permanent VP shunt rate was 9% with VAD placement under local anaesthesia and 52% when performed under general anaesthesia (p = 0.02). CONCLUSION Bedside placement of VADs for PHVD under local anaesthesia in neonates is a low-risk, well-tolerated procedure that results in at least equal results to surgery performed under general anaesthesia and/or performed in an OR.

Topical Vancomycin for Surgical Prophylaxis in Pediatric Craniofacial Surgeries. J Craniofac Surg 2019; 30:2163-2167.

Abstract
Topical vancomycin has been demonstrated to be safe and effective for reducing surgical site infections (SSIs) following spine surgery in both adults and children, however, there are no studies of its efficacy in reducing SSIs in craniofacial surgery. The SSIs are one of the most common complications following craniofacial surgery. The complexity of craniofacial procedures, use of grafts and implants, long operative durations and larger surgical wounds all contribute to the heightened risk of SSIs in pediatric craniofacial cases. A retrospective review of all open and endoscopic pediatric craniofacial procedures performed between May 2014 and December 2017 at a single children's hospital was conducted to examine SSI rates between patients receiving topical vancomycin and a historical control group. The treatment group received topical vancomycin irrigation before wound closure. An ad-hoc cost analysis was performed to determine the cost-savings associated with topical vancomycin use. A total of 132 craniofacial procedures were performed during the study period, with 50 cases in the control group and 82 cases in the vancomycin group. Overall, SSI rate was 3.03%. Use of topical vancomycin irrigation led to a significant reduction in SSIs (4/50 SSI or 8.0% in control group vs 0/82 or 0% in vancomycin group, P = 0.04). No adverse events were observed with topical vancomycin use. The potential cost-savings associated with the use of topical vancomycin as SSI prophylaxis in this study was $102,152. Addition of topical vancomycin irrigation as routine surgical infection prophylaxis can be an effective and low-cost method for reducing SSI in pediatric craniofacial surgery.

Abstract
BACKGROUND The main complication of cerebrospinal fluid (CSF) shunt surgery is shunt infection. Prevention of these shunt infections consists of the perioperative use of antibiotics that can be administered in five different ways: orally; intravenously; intrathecally; topically; and via the implantation of antibiotic-impregnated shunt catheters. OBJECTIVES To determine the effect of different routes of antibiotic prophylaxis (i.e. oral, intravenous, intrathecal, topical and via antibiotic-impregnated shunt catheters) on CSF-shunt infections in persons treated for hydrocephalus using internalised CSF shunts. SEARCH METHODS We conducted a systematic electronic search without restrictions on language, date or publication type. We performed the search on the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and Embase, with the help of the Information Specialist of the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Group. The search was performed in January 2018. SELECTION CRITERIA All randomised and quasi-randomised controlled trials that studied the effect of antibiotic prophylaxis, in any dose or administration route, for the prevention of CSF-shunt infection in patients that were treated with an internal cerebrospinal fluid shunt. Patients with external shunts were not eligible. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from included studies. We resolved disagreements by discussion or by referral to an independent researcher within our department when necessary. Analyses were also performed by at least two authors. MAIN RESULTS We included a total of 11 small randomised controlled trials, containing 1109 participants, in this systematic review. Three of these studies included solely children, and the remaining eight included participants of all ages. Most studies were limited to the evaluation of ventriculoperitoneal shunts. However, five studies included participants with ventriculoatrial shunts, of which one study contained four participants with a subduroperitoneal shunt. We judged four out of 11 (36%) trials at unclear risk of bias, while the remaining seven trials (64%) scored high risk of bias in one or more of the components assessed.We analysed all included studies in order to estimate the effect of antibiotic prophylaxis on the proportion of shunt infections regardless of administration route. Although the quality of evidence in these studies was low, there may be a positive effect of antibiotic prophylaxis on the number of participants who had shunt infections (RR 0.55, 95% CI 0.36 to 0.84), meaning a 55% reduction in the number of participants who had shunt infection compared with standard care or placebo.Within the different administration routes, only within intravenous administration of antibiotic prophylaxis there may be evidence of an effect on the risk of shunt infections (RR 0.55, 95% CI 0.33 to 0.90). However, this was the only route that contained more than two studies (8 studies; 797 participants). Evidence was uncertain for both, intrathecal administration of antibiotics (RR 0.73, 95% CI 0.28 to 1.93, 2 studies; 797 participants; low quality evidence) and antibiotic impregnated catheters (RR 0.36, 95% CI 0.10 to 1.24, 1 study; 110 participants; very low quality evidence) AUTHORS' CONCLUSIONS: Antibiotic prophylaxis may have a positive effect on lowering the number of participants who had shunt infections. However, the quality of included studies was low and the effect is not consistent within the different routes of administration that have been analysed. It is therefore uncertain whether prevention of shunt infection varies by different antibiotic agents, different administration routes, timing and doses; or by characteristics of patients, e.g. children and adults. The results of the review should be seen as hypothesis-generating rather than definitive, and the results should be confirmed in adequately powered trials or large multicentre studies in order to obtain high-quality evidence in the field of ventricular shunt infection prevention.

Abstract
PURPOSE Surgical antibiotic prophylaxis (SAP) in pediatric neurosurgery has poorly been characterized until now. This review gives an overview on the current literature extracting recommendations and guidelines. METHODS The current literature on SAP with special forcus on pediatric neurosurgerical procedures was reviewed. Further, available recommendations in online databases were checked. Clean neurosurgical, shunt, and implant surgeries are considered separately. RESULTS To date, evidence-based data on SAP in pediatric neurosurgery remain sparse and there are no standardized approaches to an adequate use of antimicrobial agents for SSI prevention for this age group. CONCLUSION Due to statistical needs, multi-center surveillance studies are needed for implementing SAP recommendations in pediatric neurosurgery.
