Plain English Summary
Background and study aims:
Two new devices have been introduced to try to reduce shunt infection; Bactiseal and Silverline shunts. This study will compare these new shunts to standard shunts. Our goal is to establish which provides most protection against infection and to ensure standardisation of care.
Who can participate?
Children and adults with newly diagnosed hydrocephalus.
What does the study involve?
Patients will be randomly chosen to receive either standard, Bactiseal or Silverline shunts. The patient will have a follow up every three months via the telephone and a questionnaire by post.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part. But there should be benefits to future patients requiring this treatment as they will potentially have reduced shunt infection.
The main risk of infection is complications for the patients which can leads to prolonged hospital stay, multiple operations and reduced IQ.
Where is the study run from?
Alder Hey Childrens Hospital NHS Foundation Trust.
When is study starting and how long is it expected to run for?
Recruitment will start in early 2013, for 2 years. Patients will be followed up for a maximum of 2.5 years.
Who is funding the study?
National Institute of Health Research Health Technology Assessment Programme

Study information
Scientific title
National three-arm, double blind multi-centre randomised controlled trial comparing Bactiseal (antibiotic-impregnated), Silverline (silver-impregnated) and standard (non-impregnated) VPS in patients with newly diagnosed hydrocephalus undergoing insertion of their first permanent shunt.

BASICS
Study hypothesis
Shunt failure due to infection has plagued this neurosurgical advance ever since it was developed. The incidence of shunt infection varies markedly in the literature from 3-27% (2-6) and is higher in certain groups, e.g. neonates and children under 1 year old, patients treated with a previous temporary external ventricular drain (EVD). Episodes of shunt infection have a significant impact on patients and the NHS and require prolonged inpatient hospitalisation, additional surgery to remove the infected hardware, placement of a temporary EVD, intravenous and intrathecal antibiotics, and further surgery to place a new shunt once the infection has been treated. Other clinical consequences of infection including epilepsy, reduced IQ and loculation have often been reported but never formally studied in the context of a prospective clinical trial. This trial thus addresses the primary question of which shunt catheter is most effective in reducing shunt infection and also has secondary questions addressing the consequences of infection in a clinical and financial context.

Condition
Newly diagnosed hydrocephalus
Intervention
We will randomly allocate patients to a standard non impregnated ventriculoperitoneal shunt (VPS), a
Silverline (Silver impregnated) VPS or a Bactiseal (antiobiotic impregnated) VPS on a ratio of 1:1:1. All VPS
used for the trial are CE marked medical devices being used for their intended purpose.

Primary outcome measures
To determine whether antibiotic or silver impregnated ventriculoperitoneal shunt (VPS) reduce early infection (within 6 months) compared to standard VPS in newly diagnosed hydrocephalus following insertion of the first de novo VPS
Secondary outcome measures
1. To determine the proportion of delayed VPS infections (occurring > 6 months following de novo insertion)
2. To determine which organisms and their resistance / sensitivities, subsequently infect these three alternative VPS
3. To assess the clinical impact of each VPS infection
4. To determine the infection rate following the first (non-infected) clean VPS revision for mechanical failure
5. To assess the cost-effectiveness and health economics of antibiotic and silver impregnated VPS compared to standard VPS
6. To improve the diagnostics of suspected shunt infections through molecular diagnostic approaches
