An update on a persisting challenge: A systematic review and meta-analysis of the risk factors for surgical site infection post craniotomy. Am J Infect Control 2024; 52:650-658. [PMID: 37989412 DOI: 10.1016/j.ajic.2023.11.005] [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: 10/24/2023] [Accepted: 11/09/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND Surgical site infections (SSIs) postcraniotomy continue to impose a significant burden on health care systems and patient outcomes. It is, therefore, important to understand their risk factors in order to promote effective preventative measures. This meta-analysis aims to provide a comprehensive, up-to-date analysis of the risk factors associated with SSIs in neurosurgical procedures. METHODS A systematic review was conducted as per preferred reporting items for systematic reviews and meta-analysis guidelines to explore existing primary evidence on the risk factors for SSIs postcraniotomy. A comprehensive search of MEDLINE, EMBASE, and Pubmed was performed from database inception up to June 2023. 43 studies were included in the meta-analysis, encompassing a total of 68,881 patients. RESULTS The strongest predictor for SSIs was found to be cerebrospinal fluid (CSF) leak (OR: 8.91, CI: 4.30-18.44). Other significant factors included infratentorial surgery (OR: 0.43, CI: 0.31-0.61), emergency surgery (OR: 1.41, CI: 1.05-1.91), reintervention (OR: 3.19, CI: 1.77-5.75), prolonged operative time (mean difference: 33.25; CI: 18.83-47.67), hospital length of stay (mean difference: 0.60; CI: 0.23-0.98) and intracranial pressure monitor (ICPM) insertion (OR: 1.81; CI: 1.06-3.11). Contrarily, sex, body mass index (BMI), diabetes, antibiotic prophylaxis, immunosuppressive agents, trauma, use of artificial implants did not demonstrate statistical significance. CONCLUSIONS This meta-analysis provides an up-to-date and comprehensive evaluation of risk factors for SSIs postcraniotomy. It emphasizes the need for preventive strategies, particularly against CSF leaks, and calls for further research to elucidate the intricate relationships between these factors.

Development and Validation of a Nomogram Prediction Model for Multidrug-Resistant Organisms Infection in a Neurosurgical Intensive Care Unit. Infect Drug Resist 2023; 16:6603-6615. [PMID: 37840828 PMCID: PMC10573443 DOI: 10.2147/idr.s411976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 09/21/2023] [Indexed: 10/17/2023] Open
Abstract
Objective To develop a predictive model for assessing the risk of multidrug-resistant organisms (MDROs) infection and validate its effectiveness. We conducted a study on a total of 2516 patients admitted to the neurosurgery intensive care unit (NICU) of a Grade-III hospital in Nantong City, Jiangsu Province, China, between January 2014 and February 2022. Patients meeting the inclusion criteria were selected using convenience sampling. The patients were randomly divided into modeling and validation groups in a 7:3 ratio. To address the category imbalance, we employed the Synthetic Minority Over-sampling Technique (SMOTE) to adjust the MDROs infection ratio from 203:1558 to 812:609 in the training set. Univariate analysis and logistic regression analysis were performed to identify risk factors associated with MDROs infection in the NICU. A risk prediction model was developed, and a nomogram was created. Receiver operating characteristic (ROC) analysis was used to assess the predictive performance of the model. Patients and Methods Results Logistic regression analysis revealed that sex, hospitalization time, febrile time, invasive operations, postoperative prophylactic use of antibiotics, mechanical ventilator time, central venous catheter indwelling time, urethral catheter indwelling time, ALB, PLT, WBC, and L% were independent predictors of MDROs infection in the NICU. The area under the ROC curve for the training set and validation set were 0.880 (95% CI: 0.857-0.904) and 0.831 (95% CI: 0.786-0.876), respectively. The model's prediction curve closely matched the ideal curve, indicating excellent predictive performance. Conclusion The prediction model developed in this study demonstrates good accuracy in assessing the risk of MDROs infection. It serves as a valuable tool for neurosurgical intensive care practitioners, providing an objective means to effectively evaluate and target the risk of MDROs infection.

Abstract
The objective of this study was to determine risk factors of pejorative evolution course in patients suffering from postoperative cranial infection. The data of patients who developed an intracranial infection after craniocerebral surgery in the neurosurgical intensive care unit of the First Affiliated Hospital of Nanjing Medical University in Nanjing, Jiangsu, China, from February 2018 to August 2019 were retrospectively analyzed. Logistic regression was used to analyze the factors influencing the prognosis of intracranial infection treatment. Sixty-four patients developed an infection after craniocerebral surgery, and 48 of them with negative CSF cultures received experimental anti-infectives. In 16 patients, cerebrospinal fluid culture showed pandrug-resistant pathogens, including 11 Acinetobacter baumannii (11), Klebsiella pneumoniae (3), Escherichia coli (1), and Candida glabrata (1). Nine patients received intraventricular or intrathecal injections of polymyxin B. The mean duration of infection treatment was 22.2 ± 9.9 days, and the clinical cure rate was 85.9% (55/64). Logistic multivariate regression analysis showed that inadequate CSF drainage (OR, 6.839; 95% CI, 1.130-41.383; P = 0.036) and infection with drug-resistant bacteria (OR, 24.241; 95% CI, 2.032-289.150; P = 0.012) were independent risk factors for postoperative intracranial infection. Intracranial infection with positive CSF culture and inadequate CSF drainage are factors contributing to the poor prognosis of intracranial infection. Moreover, early anti-infection treatment and adequate CSF drainage may improve patient outcomes. In particular, intraventricular or intrathecal injection of polymyxin B may be a safe and effective treatment strategy for MDR/XDR gram-negative bacilli infection.

Abstract
BACKGROUND Health care-associated infections (HAIs) in intensive care units (ICUs) specialized for neurocritical care (neurocritical care units [NCCUs]) are serious yet preventable complications that contribute significantly to morbidity and mortality worldwide. However, reliable data are scarcely available from the developing world. We aimed to analyze the incidence, epidemiology, microbial etiology, and outcomes of HAIs in an NCCU of a tertiary care teaching hospital in a high-income, developing country. METHODS In this 3-year retrospective cohort study, all patients admitted to the NCCU at the Ibn Sina Hospital in Kuwait for ≥ 2 calendar days were included. Patient demographics, hospitalization, and details of ICU-acquired infections were evaluated. Patient-related outcomes included hospital and ICU length of stay (LOS) and in-hospital mortality. RESULTS Among 913 patients with a total of 4921 ICU days, 79 patients had 109 episodes of HAIs. The overall incidence rate and incidence density of HAIs were 11.9/100 patients and 22.1/1000 ICU days, respectively. Multiple episodes of infection were documented in 29% of patients. The most prevalent infections were urinary tract infections (UTIs; 40/109 [37%]), bloodstream infections (30/109 [28%]), and pneumonia (16/109 [15%]). Seventy-six percent of infections were device-associated infections. A total of 158 pathogens were isolated, of which 109 were Gram-negative bacteria. Of the 40 Gram-positive bacteria, 22 were staphylococci. Seven infections were due to Clostridium difficile. There were 15 Staphylococcus aureus isolates, 47% of which were methicillin resistant. Two episodes of UTIs were due to Candida species. There were 84 Enterobacteriaceae isolates, 24% of which were extended-spectrum β-lactamase producers. All Pseudomonas aeruginosa isolates were susceptible to aminoglycosides and carbapenems. Klebsiella species were the most common pathogen (45/158 [28%]), causing pneumonia (11/33 isolates [33%]), bloodstream infections (12/37 isolates [32%]), and UTIs (16/52 isolates [31%]). One episode of bloodstream infection was due to multidrug resistant Acinetobacter baumanii which was susceptible only to colistin. Only pneumonia was independently associated with mortality, while all HAIs that occurred were significantly associated with a prolonged ICU LOS. CONCLUSIONS This is the first HAI surveillance study in an NCCU in Kuwait, and our results demonstrate the burden of HAIs on the neurologically injured patient, regardless of the site of infection. The high prevalence and resistant profile of HAIs in an NCCU in a developing country relative to a developed country has important implications for patient safety and emphasizes the need to strengthen collaboration between NCCU teams and infection control teams to prevent serious complications in this setting.

Abstract
Objectives: Neural tube defects are the second most common congenital malformation in humans. Despite significant decreases in neural tube defects and related mortality and morbidity with recent developments, infections remain an important problem. Research on the role of topical therapy for managing neural tube defects and associated infections in the neonatal period has been limited. This randomized controlled trial aimed to investigate the efficiency of topical Rifampin on infection control in paraplegic newborns with open neural tube defects.Methods: Thirty-seven patients who underwent an operation for neural tube defects were included. Topical Rifampin and cefotaxime were administered to 19 patients constituting the case group and local saline and cefotaxime were administered to a control group. Patients were examined for ventriculoperitoneal shunt infection/dysfunction, surgical site infection, urinary tract infection, and sepsis.Results: None of the patients using topical rifampin had ventriculoperitoneal shunt infection/dysfunction, surgical site infection, urinary tract infection, or sepsis. In the control group, ventriculoperitoneal shunt infection/dysfunction was found in 4 (22.2%) cases, surgical site infection in 3 (27.7%), urinary tract infection in 3 (27.7%), and sepsis in 5 (27.7%), with statistically significant differences between the groups (p = 0.01, p = 0.032, p = 0.032, and p = 0.002, respectively). No local or systemic side effect was observed regarding rifampin use.Conclusion: Topical Rifampin is effective in minimizing complications like sepsis, surgical site infection, urinary tract infection, and ventriculoperitoneal shunt infection due to neural tube defect operations. Further research with larger numbers of cases is needed to implement this practice routinely.

Abstract
BACKGROUND The pathogenesis of postsurgical pneumonia is a complicated and multifactorial process, in which elements like oral bacteria, orotracheal intubation, and dental hygiene play an important role. The objective of this study was to evaluate the efficacy of 2 types of oral hygiene interventions in decreasing cases of postsurgical pneumonia. METHODS In pediatric patients scheduled for surgery, a quasi-experimental study was carried out over a 2-year period to evaluate the efficacy of 2 types of oral hygiene interventions. There were 2 groups of intervention with 1 group for comparison. Intervention groups were tooth brushing by a dentist (intervention group 1) and dental brushing by parents + chlorhexidine gluconate (intervention group 2). Data from the year with no oral hygiene interventions were used as the baseline group. RESULTS A total of 2,535 surgical procedures were followed. Baseline group incidence of postoperative pneumonia was 10 per 1,000 surgeries, 0.2 per 1,000 surgeries in the intervention group 1 (P = .04), and 0.8 per 1,000 surgeries in the intervention group 2. Intervention group 1 was protective against postoperative pneumonia (odds ratio, 0.06; P = .02; 95% confidence interval, 0.033-0.079), but there was no benefit with intervention group 2 (odds ratio, 0.87; P = .599; 95% confidence interval, 0.52-1.46). CONCLUSIONS Dental brushing performed before surgery by a pediatric dentist was effective in reducing the incidence of postoperative pneumonia in pediatric patients.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E911. [PMID: 30871283 PMCID: PMC6466004 DOI: 10.3390/ijerph16060911] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 03/06/2019] [Accepted: 03/09/2019] [Indexed: 11/16/2022]
Abstract
Introduction: The objective of the analysis was to determine the epidemiology of healthcare-associated infections (HAIs) in neurosurgical patients, paying special attention to two time points, 2003 and 2017, in order to evaluate the effectiveness of a surveillance program introduced in 2003 and efforts to reduce infection rates. Materials and methods: Continuous surveillance during 2003⁻2017 carried out using the HAI-Net methodology allowed us to detect 476 cases of HAIs among 10,332 patients staying in a 42-bed neurosurgery unit. The intervention in this before⁻after study (2003⁻2017) comprised standardized HAI surveillance with regular analysis and feedback. Results: The HAI incidence during the whole study was 4.6%. Surgical site infections (SSIs) accounted for 33% of all HAIs with an incidence rate of 1.5%. The remaining infections were pneumonia (1.1%) and bloodstream infections (0.9%). The highest SSI incidence concerned spinal fusion (FUSN, 2.2%), craniotomy (1.9%), and ventricular shunt (5.1%) while the associated total HAI incidence rates were 4.1%, 8.0%, and 18.6%, respectively. A significant reduction was found in HAI incidence between 2003 and 2017 in regard to the most common surgery types: laminectomy (4.5% vs. 0.8%); FUSN (11.8% vs. 0.8%); and craniotomy (10.1% vs. 0.4%). Significant changes were also achieved in selected elements of the unit's work: pre-hospitalization duration, hospital stay, and surgery length reductions. Simultaneously, the general condition of patients became significantly worse: there was an increase in patients' age and decreases in their general condition as expressed by ASA scores (The American Society of Anesthesiologists physical status classification system). Conclusions: HAI epidemiology changed substantially during the study period. Among the main types of HAI, SSIs were slightly predominant, but non-surgical HAIs accounted for almost two thirds of all infections; this indicates the need for surveillance of infection types other than SSIs in surgical patients. The implementation of active surveillance based on regular analysis and feedback led to a significant reduction in HAI incidence.

Abstract
BACKGROUND Neurosurgical site infection (SSI) is a complication related to craniotomy, which may lead to severe morbidity and higher hospital costs during the postoperative period. METHODS Retrospective cohorts, case-control studies, or prospective investigations addressing risk factors of SSI updated until January 2017 were systematically searched in 2 databases (PubMed and Embase). The Newcastle-Ottawa Scale was used to evaluate quality of the included studies, heterogeneity was assessed by I2 tests, and a funnel plot and Egger test were used for the evaluation of publication bias. RESULTS There were 26 studies in total enrolled in this review. The results showed that the risk factors which had relation with SSI were other infection (odds ratio [OR], 5.42; 95% confidence interval [CI], 2.8-10.49), number of operations (>1) (OR, 2.352; 95% CI, 1.142-4.847), cerebrospinal fluid (CSF) leak (OR, 7.817; 95% CI, 2.573-23.751), CSF drainage (OR, 2.55; 95% CI, 1.58-4.11), duration of operation (>4 hours) (as for retrospective cohort studies) (OR, 1.766; 95% CI, 1.110-2.809), venous sinus entry (OR, 4.015; 95% CI, 1.468-10.982), American Society of Anesthesiologists score (>2) (OR, 1.398; 95% CI, 1.098-1.78), sex (male) (as for prospective investigations) (OR, 1.474; 95% CI, 1.013-2.145), and surgical reasons (nontraumatic) (OR, 2.137; 95% CI, 1.106-4.129). CONCLUSIONS According to the current analysis, all the factors mentioned were the risk factors for SSI after craniotomy. Patients with these risk factors should be paid more attention to prevent SSI. More evidence provided by high-quality studies is still needed to further investigate the risk factors of SSI.

Abstract
INTRODUCTION Health Care Associated Infections (HCAI) are frequent complications in neurosurgery. There is limited data available on the incidence and burden of HCAI in neurosurgical patients of Southeast Asian region. AIM To identify various HCAIs, associated aetiological agents and their antimicrobial susceptibility pattern among the patients admitted in the neurosurgery unit. MATERIALS AND METHODS An observational prospective study was carried out for three months duration on all neurosurgical patients admitted to a tertiary-care center. The site-specific nosocomial infection rates and device utilization ratios were calculated. Data on demographic profiles, invasive procedures, HCAI, isolated microorganisms and antimicrobial susceptibilities were recorded. Statistical analysis of all the variables was done. The association between categorical variables was assessed by Chi-square/Fisher-exact test. Continuous variables such as infected and non-infected were compared by Wilcoxon rank-sum test. A p-value of less than 0.05 was considered significant. RESULTS A total of 330 patients with 4054 patient-days were analysed for HCAI. Twenty-two HCAIs were identified in 21 patients. The overall rate of HCAI was 6.67% and 5.42 per 1000 patient-days. Urinary Tract Infection (UTI) was most common (71.4%) followed by Laboratory Confirmed Blood-Stream Infection (LCBI) (28.5%) and pneumonia (4.7%). No central line-associated blood stream infection was identified. Klebsiella pneumoniae and Escherichia coli were the most common organisms causing UTI and LCBI. All the isolates (100%) were found to be multidrug resistant. CONCLUSION This study generates a baseline data for records of device-associated infection in neurocritical care patients, which will further help monitoring its trend of infection and antimicrobial resistance pattern. Moreover, it will help in the formulation of the antibiotic policy and the preventive measures which may reduce morbidity and mortality.

Prophylaxis for Stress Ulcers With Proton Pump Inhibitors Is Not Associated With Increased Risk of Bloodstream Infections in the Intensive Care Unit. Clin Gastroenterol Hepatol 2017; 15:1030-1036.e1. [PMID: 28110095 PMCID: PMC5474142 DOI: 10.1016/j.cgh.2016.12.035] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2016] [Revised: 12/05/2016] [Accepted: 12/15/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Proton pump inhibitors (PPIs) have been associated with increased risk of infection, likely because of changes in intestinal epithelial permeability and the gastrointestinal microbiome. PPIs are frequently given to patients in the intensive care unit (ICU) to prevent stress ulcers. These patients are at risk for bloodstream infections (BSIs), so we investigated the relationship between PPI use and BSIs among patients in the ICU. METHODS We performed a retrospective cohort study of adults (≥18 years) admitted to 1 of 14 ICUs within a hospital network of 3 large hospitals from 2008 through 2014. The primary exposure was PPI use for stress ulcer prophylaxis in the ICU. The primary outcome was BSI, confirmed by culture analysis, arising 48 hours or more after admission to the ICU. Subjects were followed for 30 days after ICU admission or until death, discharge, or BSI. Multivariable Cox proportional hazards modeling was used to test the association between PPIs and BSI after controlling for patient comorbidities and other clinical factors. RESULTS We analyzed data from 24,774 patients in the ICU, including 756 patients (3.1%) who developed BSIs while in the ICU. The cumulative incidence of BSI was 3.7% in patients with PPI exposure compared with 2.2% in patients without PPI exposure (log-rank test, P < .01). After adjusting for potential confounders, PPI exposure was not associated with increased risk of BSI while in the ICU (adjusted hazard ratio, 1.08; 95% confidence interval, 0.91-1.29). Comorbidities, antibiotic use, and mechanical ventilation were all independently associated with increased risk for BSIs. CONCLUSIONS In a retrospective study of patients in the ICU, administration of PPIs to prevent bleeding was not associated with increased risk of BSI. These findings indicate that concern for BSI should not affect decisions regarding use of PPIs in the ICU.

Abstract
BACKGROUND Data on nosocomial bloodstream infections (NBSI) in neurosurgery is limited. This study aimed to analyze the epidemiology, microbiology, outcome, and risk factors for death in neurosurgical patients with NBSI in a multidrug resistant setting. METHODS Neurosurgical patients with a confirmed NBSI within the period 2003-2012 were retrospectively analyzed. NBSI was diagnosed when a pathogen was isolated from a blood sample obtained after the first 48 h of hospitalization. Patients' demographic, clinical, and microbiological data were recorded and analyzed using univariate and multivariate analysis. RESULTS A total of 236 patients with NBSI were identified and 378 isolates were recovered from blood cultures. Incidence of NBSI was 4.3 infections/1000 bed-days. Gram-negative bacteria slightly predominated (54.5 %). The commonest bacteria were coagulase-negative staphylococci (CoNS, 26 %), Klebsiella pneumoniae (15.3 %), Pseudomonas aeruginosa (14.8 %), and Acinetobacter baumannii (13.2 %). Carbapenem resistance was found in 90 % of A. baumannii, in 66 % of P. aeruginosa, and in 22 % (2003-2007) to 77 % (2008-2012) of K. pneumoniae isolates (p < 0.05). Most CoNS and Staphylococcus aureus isolates (94 and 80 %, respectively) were methicillin-resistant. All Gram-negative isolates were sensitive to colistin and all Gram-positive isolates were sensitive to vancomycin and linezolid. Antimicrobial consumption decreased after 2007 (p < 0.05). Overall mortality was 50.4 %. In multivariate analysis, advanced age and stay in an Intermediate Care Unit (IMCU) were independent risk factors for in-hospital mortality (p < 0.05). CONCLUSIONS Overall, high incidence of NBSI and considerable resistance of Gram-positive and particularly Gram-negative bacteria were noted in neurosurgical patients. Mortality was high with advanced age and stay in IMCU being the most important death-related factors.

Abstract
OBJECTIVE To define the relationships between age, sex and hospital-acquired infection (HAI) rates in a national cohort of hospitalized patients. METHODS Analysis of chart-abstracted Medicare Patient Safety Monitoring System data from randomly selected medical records of patients hospitalized between January 1, 2009, and December 31, 2011, for acute cardiovascular disease, pneumonia, or major surgery associated with 1 of 6 HAIs. Patients were stratified into 6 groups. We then analyzed the association of age, sex, and 2 outcomes; the rate of occurrence of HAI for patients who were at risk and the rate of patients having at least 1 HAI. RESULTS Among 85,461 patients, all groups except younger female surgical patients had higher catheter-associated urinary tract infection (CAUTI) rates than male patients. After adjustment for comorbidities, there was no overall evidence of higher HAI rates among elderly patients. In patients with acute cardiovascular disease, women had higher rates of HAIs. Among patients with pneumonia, there was no significant difference in the rate of HAIs among most age and sex groups. Among surgical patients, all age and sex groups had a significantly higher adjusted rate of developing at least 1 HAI except females 65 years of age or older. Similar results were seen for the outcome of the occurrence rate of HAIs. CONCLUSIONS There was not an overall increased risk of HAIs among older patients hospitalized for acute cardiovascular disease, pneumonia, and major surgery after adjustment for comorbidities. The relationship between sex and the rate of HAIs varied depending upon the underlying acute reason for hospitalization.
