EVD Infection Prevention Bundles: Where the Catheter Fits

An EVD infection prevention bundle is a set of practices that a hospital applies to every drain, from insertion through daily maintenance to removal. Catheter choice is one element of that bundle. An antibiotic-impregnated catheter is designed to help reduce the risk of colonization, but it works alongside sterile insertion, closed-system handling and timely removal, not instead of them.

Drain-related ventriculitis is one of the complications neurocritical care teams work hardest to avoid, and most hospitals now manage it through bundles rather than individual measures. For distributors, understanding the structure of a bundle is essential: it explains why infection prevention teams ask the questions they do, and it places the catheter where it belongs in the conversation. This article maps a typical bundle and shows where the device fits.

What is an EVD bundle?

A bundle is a small group of evidence-informed practices that are applied together, consistently, to every patient. The idea is that reliable execution of several measures does more than any single measure on its own. EVD bundles typically follow the life of the drain in three phases: insertion, maintenance and removal. Consensus guidance on EVD insertion and management and infectious disease guidelines on healthcare-associated ventriculitis both inform the elements hospitals choose.

Each hospital writes its own bundle, adapted to its patients and resources. The elements below are common, but the specifics belong to the hospital.

What happens at insertion?

Insertion is the first opportunity for contamination and receives careful attention in most bundles. Common elements include:

• Hand hygiene and full sterile barrier precautions for the operator.
• Hair clipping rather than shaving at the insertion site.
• Skin antisepsis according to hospital policy.
• Tunneling the catheter under the scalp away from the entry point, according to surgeon practice.
• Periprocedural antimicrobial practice as set by hospital protocol.
• Secure fixation and a sterile dressing at the exit site.
• Selection of the catheter version according to the hospital’s protocol.

The device role at this stage is to arrive sterile, intact and complete, with packaging that opens cleanly onto a sterile field, and with both catheter versions available where drains are placed.

What happens during maintenance?

Maintenance covers the days or weeks the drain is in place, and it is where nursing practice matters most. Typical elements include keeping the system closed, minimizing access for sampling and flushing, using aseptic technique whenever the system is accessed, regular inspection and care of the dressing, consistent leveling, careful handling during transport and documentation of every access. Many hospitals also audit these practices regularly.

Device design influences maintenance through usability. A clear scale, a readable drip chamber, a drainage bag with sensible capacity and clearly identified clamps make correct handling easier. The EVD-010 Series, with its 30 cm measuring scale, 150 ml drip chamber and 800 ml drainage bag, is designed around these daily tasks.

What happens at removal?

Infection risk is linked to how long a drain stays in place, so many bundles include a daily review of whether the drain is still needed. When the clinical team decides the drain can come out, removal follows the hospital protocol, and some protocols include sending the catheter tip for culture in specific situations. When a patient needs permanent CSF diversion, the conversion to a shunt is planned as a separate procedure.

The removal phase also matters for documentation. Recording the catheter version and lot at placement, and the date of removal, gives infection prevention the information it needs to analyze its own data later. A supplier can help by making the catheter version easy to identify, as the orange color of DESU antibiotic-impregnated catheters does, and by printing lot numbers clearly on labels that can be transferred to the record.

Where does the catheter fit in?

Catheter choice is the bundle element where the device plays the most direct role. The DESU range offers a standard catheter and an orange antibiotic-impregnated catheter designed to release its agent in a controlled way over 28 days. The ventricular catheter kit, with its radiopaque silicone catheter and tantalum length marks from 5 to 15 cm, is available in both versions, as is the lumbar drainage catheter kit for external lumbar drainage.

Hospitals use the antibiotic-impregnated version in different ways: some for every drain, others for selected patients according to criteria the neurosurgery and infection prevention leads agree. The bundle document should state which approach applies, so that the selection is consistent and auditable.

How should a distributor talk about the catheter?

Infection preventionists are precise, and they expect suppliers to be precise too. Useful principles:

• Present the catheter as one element of the bundle, never as the solution on its own.
• Use careful verbs: “designed to” and “intended to help reduce the risk of colonization.”
• Avoid quoting infection rates unless they come from a published source the team can read.
• Do not name or discuss the agent in marketing conversations; route technical questions to the manufacturer.
• Support the hospital’s selection protocol rather than proposing your own.

How are bundles audited, and what helps?

A bundle only works if it is followed, so most hospitals audit compliance. Infection prevention or nursing quality teams observe insertions, review documentation and check maintenance practices at the bedside, then feed results back to the units. Typical audit questions ask whether the insertion checklist was completed, whether the catheter version matched the protocol, whether the dressing was intact and dated, whether every system access was documented and whether the need for the drain was reviewed each day.

Device-related information makes some of these questions easier to answer. A catheter version that is visually distinct, item codes that differ clearly between versions, and lot numbers that can be scanned or copied into the record reduce ambiguity during an audit. A distributor can also help by sharing usage data by catheter version, so the hospital can compare purchasing with its protocol. Those are modest contributions, but infection preventionists notice suppliers who make their work easier.

How else can a distributor support the bundle?

Beyond the catheter, a distributor contributes through training and supply. Short, IFU-based sessions on system handling help nurses maintain a closed system. Reliable stock of both catheter versions, in every location where drains are placed, means the protocol can be followed at three in the morning. Accurate lot recording supports traceability if a product question arises. And documented answers to technical questions give the infection prevention team confidence in the supplier.

DESU designs and manufactures its catheters and drainage systems in its own cleanrooms in Ankara, Türkiye, under ISO 13485, and its products carry the CE mark. Distributors can request documentation and written technical answers directly from the manufacturer to support infection prevention reviews.
