Abstract

Objectives: To assess the incidence of infection following various cerebrospinal fluid (CSF) shunt procedures among patients with hydrocephalus and related conditions, based on the age of the patient, and to determine the types of pathogens responsible for shunt infections.

Methods: This retrospective single center study reviewed the records of patients with culture-confirmed CSF shunt infection diagnosed between January 2012 and December 2017. Cases without central nervous system imaging investigations were excluded.

Results: The incidence rate of shunt-related infections was 32.2%. Among the 189 patients whose records were included, Staphylococcus epidermidis (47.5%) and Acinetobacter baumannii (18%) were the most common causative organisms. The incidence of postoperative infection was higher among those who underwent external ventricular drain procedures (65%) than among those who underwent ventriculoperitoneal shunt procedures (24%). There were no intraoperative deaths. However, the postoperative death rate was 12.2% during hospital stay (mean duration = 9 days); 2% of these deaths occurred after shunt removal.

Conclusion: The incidence of infections after CSF shunt procedures was high in our tertiary academic hospital during the study period, compared to those reported in similar clinical settings and before developing a detailed standardized protocol for infection control. Although gram-negative organisms were the most prevalent cause of CSF infections, S. epidermidis (a gram-positive organism) was the most commonly encountered causative agent. Shunt protocols should be implemented to address perioperative shortcomings and to reduce overall mortality and morbidity.

Hydrocephalus is a commonly observed condition in neurosurgical practice; it requires cerebrospinal fluid (CSF) diversion. In Saudi Arabia, the incidence of hydrocephalus is higher than that in most other countries, because of the high rate of marriages and the prohibition of abortion.1 The national prevalence of congenital hydrocephalus is estimated to be 0.8 to 1.6 per 1,000 live births.1-3 Although the primary complications of shunt procedures include obstruction and drainage problems, postsurgical infections are the most common, immediate, life-threatening complications.1,4,5

Shunt infections are usually caused by nosocomial organisms as well as community-acquired pathogens; they cause clinically significant morbidity and mortality rates worldwide.6 The rate of infection following CSF diversion procedures ranges from 4% to 30%.7 In the United States, infection rates range from 4.1% to 17.4% of patients and from 2.5% to 12.3% based on the type of CSF diversion procedure conducted.8 In countries like the Arabian Peninsula, figures on the incidence of shunt infections are scarce and vary from 3% to 52%.1,4

Typically, shunt infections occur 15 days to 12 months following surgery. Most shunt infections are caused by gram-positive organisms, with coagulase-negative staphylococci causing 17-78% and Staphylococcus aureus causing 44-30% of shunt infections.9 The symptoms of postoperative shunt infections include the following: a mild or, rarely, severe fever; nausea; vomiting; malaise; and lethargy and a loss of appetite, especially when the infection develops into bacteremia. Shunt infections are often associated with wound dehiscence, which causes patients to revisit healthcare facilities.10

The type of surgery in which the surgical incision passes pathogens from the skin to internal body organs (such as the brain) is one of the essential causes of shunt infections. Furthermore, the infection might spread locally from one site to another via either hematogenous, airborne, or direct contact with the source.6 The use of ventriculoperitoneal shunt (VPS), external ventricular drain (EVD), or endoscopic third ventriculostomy (ETV) in patients with hydrocephalus divert CSF from the ventricles to the peritoneum and collecting system or to the basal tank. This allows for an opportunity for transmission of infections to the central nervous system (CNS), resulting in conditions such as meningitis and cerebral abscesses.11

This study aim to determine the incidence rate of shunt infections and the primary causative organisms among patients who underwent shunt surgery in a tertiary academic hospital in Saudi Arabia. Additionally, we aim to review the patients’ clinical, radiological, and microbiological features.

Methods

A cross-sectional retrospective review was conducted among patients treated for CSF shunt infections at, a 600-bed tertiary academic public hospital, King Fahd Hospital of the University, Dammam, Saudi Arabia, between January 2012 and December 2017. Ethical approval was obtained from the Institutional Review Board of Imam Abdulrahman Bin Faisal University. As a result of the retrospective nature of the study, the need for informed consent was waived. This study was conducted according to the principles of the Helsinki Declaration.

Our literature search was extensive, comprehensive, and was only influenced by study quality and suitability. Data were obtained from patients’ electronic medical records. The International Classification of Diseases (ICD-9) keyword “CNS infections” was used to identify the electronic medical files of patients treated for CNS infections. Next, we reviewed the hospital database to identify cases of shunt infection that occurred during the 6-year study period. Data on patient demographics, underlying conditions, causative microorganisms, type of shunt device, and the time between surgery and diagnosis were extracted. Infections were categorized as early (<1 month after shunt surgery), delayed (1 to 12 months after surgery), or late (≥12 months after surgery).

Patients were included in the study if they had a positive microbiological culture within 120 hours after surgery, a postoperative fever (temperature >38.2°C), and available CNS imaging data. Cases of shunt infection in which the shunt was removed before determination of the causative organism and cases in which the patients were diagnosed in different health facilities were excluded.

Statistical analysis

Statistical analyses were performed using Statistical Package for Social Sciences, version 21.0 (IBM Corp, Armonk, NY, USA). Descriptive results were reported as frequencies and percentages. Comparisons between groups were performed using analysis of variance, and the Kruskal-Wallis test was used to test the significance of differences between groups. P-values <0.05 were considered statistically significant.

Results

Of the 266 patients who underwent a CNS shunt procedure, 189 (71.1%) met the inclusion criteria. Of the patients with shunt infections, 32.3% had a positive CSF culture (Table 1).

Incidence of shunt infections based on age.

The incidence of infection was the highest among patients with an EVD (29/52, 56%), followed by patients with an VPS (31/131, 24%), and an ETV (1/6, 15%). The incidence of infection differed significantly based on the type of procedure conducted (p=0.02). The incidence of infection was the highest among patients with post-traumatic hydrocephalus (4/8, 50%). The rate of infection was also high among those with congenital hydrocephalus (29%), spina bifida with hydrocephalus (33%), and hydrocephalus secondary to a vascular abnormality (45%); however, the incidence of infection did not differ significantly based on the type of underlying condition (Table 2).

Incidence of shunt infections based on the diagnosis at admission.

The majority of shunt infections (52.8%) were caused by gram-negative microorganisms. Gram-positive bacterial caused 44% and fungal pathogens caused 3.3% of the infections. Among the 61 cases of bacterial infections, Staphylococcus epidermidis (S. epidermidis) was the most common cause of infection (29/61, 48%), followed by Acinetobacter baumannii (11/61, 18%) (Figures 1 & 2), (Table 3). Less frequently cultured microorganisms included group A beta-hemolytic Streptococci, group B Streptococci, group B Aspergillus, Proteus mirabilis, Pseudomonas species, and S. hominis.

There were no intraoperative deaths. However, the postoperative death rate was 12.2% during hospital stay; 2% of postoperative deaths occurred after the shunt was removed. The mean duration of hospital stay was 9 days.

Discussion

The burden of infantile hydrocephalus in Saudi Arabia, a developing country, is significantly higher than those in other developed countries, including Sweden, England, Wales, and Japan. The incidence of congenital hydrocephalus in Saudi Arabia is estimated to be 0.81 to 1.6 per 1000 live births.1-3

In this study, the incidence of shunt infections exceeded 32%, which is significantly higher than that reported in similar clinical settings.9,10 Additionally, the causative organisms differed from those found in previous studies conducted in Saudi Arabia, with some new pathogens, such as Serratia marcescens, being identified.3 Thus, management of the factors that contribute to the high rate of shunt infections; such as hygiene, wound care by the patient or the nursing staff, duration of hospital admission, experience of the surgeon, surgical technique used, duration of the procedure, and handling of the indwelling device during surgery; and the more frequent use of antibiotics than that in other countries are required. However, this may lead to the emergence of antibiotic resistance, thus limiting antibiotic choices and efficacy in the future.

Use of VPS is known to be associated with a higher rate of infection than the use of other methods of CSF diversion.11 However, in our study, the rate of infection was higher following EVD procedures, despite VPS procedures being the most commonly performed procedure. It has been reported that the incidence of postsurgical VPS infection ranges from 3% to 9% in Western countries and from 9% to 32% in African countries; the incidence is lower in developed countries.12 In countries in sub-Saharan Africa, especially in regions with endemic bacterial infections, it is advisable to use empirical broad-spectrum antibiotics to prevent postoperative infection.13 Until recently, the use and effects of prophylactic antibiotics have been a source of debate.12,13 For the best results, it is essential to target the most commonly implicated pathogens when administering prophylactic antibiotics before patients undergo surgery.

Sarguna and Lakshmi14 retrospectively analyzed the records of 226 patients who had undergone shunt procedures and found only 9 shunt infections (overall infection rate: 4%); the other CSF and blood cultures were sterile. Their study results indicated that CSF cultures may be negative even when the shunt device harbors infection.15

Staphylococcus species are mainly present on the skin and superficial areas; hence, it is difficult to prevent infections cause by these bacteria.10 This explains why surgical incisions are prone to staphylococcal infections. Staphylococcus epidermidis, which is a part of the normal skin flora, was the most commonly encountered organism in our study; this is in keeping with reported international figures. Staphylococcus epidermidis is a permanent and pervasive colonizer of human skin, and there is a high chance of device contamination during insertion through the scalp skin (Figure 2).16,17

Although most (90%) shunt infections occur within 20 days of surgery, some infections may not occur until many years after surgery.10 Viereck et al15 reported that symptoms of cryptococcal infection started 10 days to 15 months after shunt placement. They also reported a case involving a VPS procedure in which a cryptococcal infection was only detected 20 years after VPS placement. This type of infection is an infrequent complication of VPS, and only 9 cases of shunt-related cryptococcal infections have been reported to date.18 Having said that, our results did not reveal any cases of cryptococcal infection.

Based on imaging findings, the majority of CNS infections can be classified based on their MR sequences T1 and T2 weighted imaging and contrast enhancement characteristics. Ring enhancing lesions, basal ganglia space-occupying lesions, and gray and white matter hyperintensities are common patterns. Imaging is of substantial importance to detect the signs of infection caused by pyogenic bacteria in the subarachnoid space, brain parenchyma, ventricles (ventriculitis or pyocephalus), and the potential extra-axial spaces (epidural or subdural empyema). Similar to parenchymal abscesses, pus in the ventricles (occipital horns) or epidural or subdural space shows restricted diffusion, a useful finding for distinguishing simple effusion from empyema in the context of acute bacterial meningitis (Figures 1 & 2). Magnetic resonance spectroscopy is useful to evaluate necrotic masses; for example, infections with a central necrotic cavity lacking normal brain metabolites (choline, creatine, and n-acetyl aspartate) can be evaluated using this technique. Restricted diffusion or periventricular enhancement depends on whether the patient can mount an inflammatory response against pathogens (Table 3).19-26

Cerebrospinal fluid shunt infections caused by Candida albicans (C. albicans) are rare because this fungal agent only thrives well among individuals in immunosuppressed states.18 Cancer patients, those receiving chemotherapy, or individuals with HIV infection are at higher risk of these CSF shunt infections.12 In this study, C. albicans was identified in CSF cultures from immunocompetent patients (2.5%), even though it is difficult to isolate C. albicans from immunocompetent patients in the laboratory.27

The incidence of CSF shunt infections varies with age; it has been reported to be the highest among infants and to decline with increasing age.12,14 However, this was not the case in our study. The rate of infection was the highest in elderly patients, adults, and pre-school children. This observation concurs with the proposed factors attributing to postoperative infections, including patient age, immune status, environmental exposure, and nutritional status.28 Environmental exposure is the presence of microorganisms that can cause infection. Age is closely related to the immune status. This explains why the least virulent organisms affect children and elderly patients more frequently than the rest of the population.

Cerebrospinal fluid infection is a major concern in the neurosurgical field due to the following reasons: i)adverse cognitive outcomes; ii) high rates of morbidity and mortality; ii) need for prolonged courses of antibiotics following hospitalization; iv) negative psychosocial impact on patients and families; and v)need for shunt revisions. The fact that there is a foreign shunt placed in the body significantly contributes to the development of CSF infections among patients undergoing procedures involving incisions in the ventricular system.28 Insertion of shunt devices requires proper diagnosis and handling; therefore, only sterilized hardware (sterilized by steam, ethylene oxide, and other low-temperature sterilizers) should be used.

Precautions are needed to reduce the rate of CSF infections. Bacteremia must be ruled out based on results of complete white blood cell count, inflammatory markers, and other laboratory procedures. Additionally, if patients and physicians adhered to infection control, bacteremia is less likely to occur. Additionally, attempts should be made to minimize the number of operative room personnel, shorten the operative time, and ensure proper instrument sterilization.28 Recently, a detailed standardized protocol was published for use during CSF shunt surgeries to prevent postoperative infection regardless of the patient’s age.29 The protocol includes guidance on the control of the surgical environment to minimize contamination from air, double gloving, local injection of antibiotics, and detailed postoperative management. The protocol also provides guidance on immersion of devices, optimal timing of skull x-ray, and detailed postoperative management.

Furthermore, at our facility, we advise strict follow-up at the outpatient clinic within 2 weeks of discharge, to assess the surgical wound margins, CSF culture results from the shunt aspirate, blood test, and culture results. Patient attendance at the clinic is significantly influenced by their health-seeking behaviors, which may influence the development of postoperative complications. Thus, we employed a number of strategies to ensure that patients attended their follow-up appointments, such as scheduling in-person follow-up care appointments at the patient’s convenience. Additionally, we attempted to adhere to the core principle of providing the patient or the patient’s parents’ with comprehensive health education, including information on the health condition and possible complications.

Study limitations

This was a retrospective study conducted at a single center, with a small sample size. As this retrospective study relied on accurate data collection and documentation, interpretation may have been limited by the validity and generalizability of our findings either by information or election bias. Also, this limited our ability to assess the age-specific incidence of infection. Additionally, we did not investigate some confounding factors that may influence our findings, such as the incidence of multiple infections in the same patient.

In conclusion, the incidence of infection after CSF shunt procedures was high in our hospital during the study period, and was significantly higher than the rate observed in other similar clinical settings before developing a detailed standardized protocol for infection control. Although gram-negative organisms were the most common cause of CSF infections, S. epidermidis (a gram-positive organism) was the single most frequently encountered organism. The postoperative infection rate was higher following EVD procedures than following VPS procedures, despite the fact that the VPS procedure was more commonly used. Shunt protocols should be implemented to address perioperative shortcomings and to reduce overall hospital stay, mortality and morbidity.

Emphasizing and encouraging the surgeons on giving the patients clear instructions and educating them on infection control measures might help in decreasing the infection rate. Further study is needed to be conducted in order to formulate an optimal management strategy for these patients.
