Ambulatory Surgery Centers and Neuro Products: Where EVD Fits

External ventricular drainage is generally not an ambulatory surgery center product. An EVD stays in place for days and needs neuro-ICU monitoring, while ASCs are built for planned procedures with same-day discharge. For a neuro distributor, ASCs matter for outpatient spine products such as dural grafts and bone grafts, and EVD effort belongs in hospitals.

What do ambulatory surgery centers do in neurosurgery and spine?

Ambulatory surgery centers, or ASCs, perform scheduled procedures for patients who are expected to go home the same day or, in some settings, after a short stay. Over recent years, a growing share of spine surgery has moved into this setting, particularly decompressions, discectomies and selected fusion procedures in carefully chosen patients. Pain management procedures are also common.

What ASCs do not do is emergency neurosurgery or care that requires an intensive care unit. Cranial surgery for hemorrhage, trauma or tumors, and the management of acute hydrocephalus, remain hospital activities. ASCs plan for the unexpected with transfer arrangements to nearby hospitals, but they are not designed to manage patients who need continuous neurological monitoring.

Why is EVD not an ASC product?

The reasons follow directly from how an EVD is used:

• It is placed for acute conditions, such as hemorrhage, trauma or obstructive hydrocephalus, that arrive as emergencies rather than scheduled cases.
• It stays in place for days, connected to a collection system that must be leveled, adjusted and monitored around the clock.
• It is managed by neuro-ICU nurses trained in drainage care, with neurosurgical and neurocritical care teams available at all times.
• Patients with an EVD are critically ill and need frequent neurological assessment and imaging.

None of this fits the ASC model. A distributor who spends time presenting the EVD-010 Series to an ASC is unlikely to find a buyer, and may lose credibility with administrators who know exactly what their center does and does not do.

Are there any edge cases?

Very few. Lumbar drainage, for example, is sometimes used after spine surgery to manage a CSF leak, but a patient who needs a lumbar drain is generally admitted to a hospital for monitoring. Shunt surgery is typically performed in hospitals as well, given the need for postoperative observation and the possibility of complications.

The closer connection between ASCs and CSF management is preventive. Outpatient spine surgeons encounter incidental durotomies, and their centers need a plan for repairing them. That is a dural graft and sealant question, not a drainage question, and it is where DESU's collagen products become relevant.

Which neuro products do fit an ASC?

The table below summarizes where DESU's neurosurgery and biomaterial products stand in the ASC setting.

For outpatient spine, DURASHEET is a dural graft matrix of pure Type I bovine collagen in four sizes, usable on both surfaces, suturable, ready to use and gamma sterilized. DECOLL is a collagen dura membrane of pure Type I bovine collagen in four sizes, intended for onlay use, also ready to use and gamma sterilized. DEBONE and XENOBONE are collagen bone grafts with β-TCP. Ready-to-use formats suit ASCs, where turnover is fast and staff want products that do not add preparation steps.

What ASC buyers ask about grafts

ASC buyers are usually close to the operating room and to the center's finances at the same time. Their questions are direct: which sizes do our surgeons actually need, how much storage space does the product take, what is the shelf life, how quickly can you replace stock, and can the product be opened only when it is needed? They also want simple documentation: product information, sterility and storage details, and lot information for their implant records. A distributor who arrives with a proposed size mix based on the center's case types, rather than the full catalogue, saves the buyer time and shows an understanding of how a small center operates.

How should a distributor split time between ASCs and hospitals?

A distributor with a neurosurgery bag that includes EVD, shunts and dural grafts should plan coverage by product, not by building. A simple approach:

• Hospitals with neurosurgery coverage: EVD and lumbar drainage, shunts and catheters, dural grafts for cranial and spine cases.
• Trauma and stroke centers: concentrated EVD effort, because that is where drains are placed most often.
• ASCs with spine programs: dural grafts and bone grafts, with attention to ready-to-use formats, simple storage and reliable delivery.
• Hospital outpatient departments: assess case by case, since they may share stock, staff and policies with the main hospital.

This keeps EVD effort where it can convert, and gives ASC visits a clear purpose.

Planning ASC visits around the schedule

ASCs run tight, predictable schedules, and staff have little time between cases. Visits work best when they are short, booked in advance and focused on one topic: a size review, a delivery issue, an in-service for new scrub staff. Unplanned visits during a busy block are rarely welcome. In hospitals, by contrast, EVD support often means being available when a unit needs help, including evenings for night-shift in-services. Recognizing these different rhythms helps reps plan a week that serves both.

Can ASC relationships still support an EVD line?

Yes, indirectly. The spine and neurosurgeons who operate in ASCs often also take call at hospitals, sit on hospital committees and influence product decisions there. A distributor who supports them well in the ASC, with reliable dural graft supply and prompt answers, builds credibility that carries over when the same surgeons discuss drainage systems at the hospital.

ASC ownership structures can also link centers to hospital systems. Where an ASC is part of, or affiliated with, a health system, the supply chain team may be the same people who manage hospital contracts. Knowing those connections helps a distributor plan conversations that cover both settings without confusing them.

What should an ASC conversation avoid?

Avoid leading with products the center cannot use. Do not position EVD, lumbar drainage or shunts as ASC items, and do not suggest that outpatient surgery reduces the need for hospital-based CSF management. Focus on what the center actually does: efficient, well-planned spine procedures where incidental durotomy repair and bone grafting need dependable, ready-to-use products. Respecting the boundaries of the ASC model is part of being taken seriously by its administrators and surgeons.

It also helps to avoid overloading the center with stock. Small facilities have limited storage, and a graft that sits on the shelf until it expires is a cost they remember. Propose modest quantities, agree a reorder point, and review usage after the first months rather than pushing volume at the start.

Talk to a DESU product specialist

If you cover both hospitals and ambulatory surgery centers, DESU's product specialists can help you decide which products to lead with in each setting, from EVD systems for neuro-ICUs to dural and bone grafts for outpatient spine.
