Plain English Summary
Background and study aims
A peripherally inserted central catheter (PICC) is a long, thin tube that goes into a vein in the upper arm. Babies in neonatal units often need to take medicines and fluids through PICCs for a long time. PICCs are inserted in order to avoid the need for repeated painful procedures and can stay in place for several weeks. However, very occasionally these PICCs can cause infections in the blood. There are currently two types of PICCs available. One type is coated with an antibiotic and an antifungal which might prevent infection by killing bacteria (AM-PICC), and the other type is not (a standard PICC). Although both are available, currently hospitals tend to use the standard PICC (S-PICC). We are currently investigating antimicrobial catheters in children, however, we also need to find out which catheter (PICC) is better in babies or if there is no difference between them. The study will help hospitals to decide which type of PICC to use for babies admitted to neonatal intensive care in the future.
Who can participate?
Babies who require the narrowest PICC.
What does the study involve?
Participating babies will be randomly allocated to be treated with either an AM-PICC or a S-PICC. The study will follow your baby using routine records and will use infection results from samples that need to be taken as part of your baby's routine clinical care. When your baby's PICC is removed, we will also test the tip for bacteria. Information will also be collected from the babies' hospital admission up till 6 months after they have entered the study.
What are the possible benefits and risks of participating?
Both PICCs are CE marked for use in babies which means they comply with EU legislation. Currently normal practise in hospitals is to use the standard PICCs; however, there is no evidence to support that these are better or worse than AM-PICC. For all PICCs there is a small risk that they may become infected and cause an infection in the blood. By using the antimicrobial PICCs this risk of infection may decrease. As the antimicrobial PICCs do contain a tiny amount of antibiotic and antifungal, there is a potential that instead of being beneficial they could be problematic. However, the main foreseeable disadvantage, that bacteria/fungi might become resistant to the antibiotic/antifungal, is very unlikely indeed to have any impact on a baby's care.
Where is the study run from?
The study will be run from 18 neonatal units in the UK. The lead centre will be Bradford Teaching Hospitals NHS Foundation Trust. The study will be co-ordinated through the Medicines for Children Clinical Trials Unit, University of Liverpool.
When is the study starting and how long is it expected to run for?
The study will run from December 2014 until August 2017.

| Scientific title | An unblinded, two-arm randomised controlled trial to determine the effectiveness and cost-effectiveness of antimicrobial impregnated (with rifampicin and miconazole) long lines (termed peripherally inserted central venous catheters, or AM-PICC) compared with standard PICC (S-PICC) for reducing blood stream infection (BSI) |
| Study acronym | PREVAIL |
| Study hypothesis | The overall aim of the study is to determine whether AM-PICC should be introduced across the NHS for preterm babies. In very preterm infants, does the use of antimicrobial impregnated PICC, compared to standard PICC, reduce blood stream infection and is it cost effective?

| Ethics approval(s) | NRES Committee -Yorkshire & The Humber - Sheffield, 31/10/2014, Ref: 14/YH/1202 |
| Condition | Infectious disease, preterm babies requiring a PICC |
| Intervention | 1. Antimicrobial impregnated (with rifampicin and miconazole) peripherally inserted central venous catheters (AM-PICC) 2. Standard PICC (S-PICC) |
| Intervention type | Device |
| Pharmaceutical study type(s) | |
| Phase | |
| Drug / device / biological / vaccine name(s) | |
| Primary outcome measure | Time to first blood stream infection based on a positive blood culture (including fungal BSI) taken between 24 hours after randomisation until 48 hours after removal. As part of the primary endpoint there will be two sensitivity analyses: 1. A sensitivity analysis confined to clinically serious BSI defined by positive culture and the baby is treated for more than 72 hours with intravenous antibiotics or dies during treatment 2. Time to first BSI based on a positive blood culture (including fungal BSI) taken between 24 hours after PICC insertion until 48 hours after removal |
| Secondary outcome measures | 1. Rifampicin or miconazole resistance in any isolate from blood culture 2. Rifampicin or miconazole resistance in any isolate from PICC tips 3. Death within 6 months of randomisation 4. Death before discharge 5. Rate of BSI per 1000 PICC-days (including recurrent BSI) 6. Rate of one or more BSI 7. Rate of catheter-related BSI 8. Time to a composite measure of BSI including culture-negative BSI (based on reason for antibiotic treatment beyond 72 hours after a negative blood culture sample) 9. Rate of blood culture sampling per 1000 PICC days 10. Duration of antimicrobial exposure from randomisation up to 48 hours after line removal 11. Rate of chronic lung disease 36 weeks postmenstrual age 12. Rate of necrotizing enterocolitis (NEC): Bells stage II or III 13. Rate for treatment for retinopathy of prematurity before NNU discharge 14. Rate of abnormalities on cranial ultrasound 15. Time to full milk feeds after randomisation 16. Breast milk intake at discharge from NNU 17. Total duration of parenteral nutrition from randomisation until discharge from NNU 18. Time to PICC removal |
