Between Debridements: The Wound Care Infrastructure Problem Nobody Names

Mr. Gary Lane walked into the emergency department of Cabrolles Regional Hospital in rural Texas on a Tuesday night in late spring, leaning on a cane he didn't usually need, with a wound on the bottom of his right foot that had stopped looking like the kind of thing he could handle at home.
He was sixty-seven and had Type 2 diabetes, the way half of Cabrolles did. He had pulses in both feet that Dr. Alexander Blackwell could find with his fingers before he ever reached for a Doppler. By every clinical measure that matters, the wound on Gary's foot was a healable wound. The 2024 international Delphi consensus on wound bed preparation in resource-limited settings, developed by forty-one wound experts across fifteen countries and published in Advances in Skin & Wound Care, establishes the published benchmark for a wound like Mr. Lane's: 20-40% smaller by week four, fully healed by week twelve.¹
Wednesday morning, Dr. Blackwell performed a sharp debridement at the bedside. Judy Carter, the WOCN who covered wound care for the entire twenty-five-bed facility, assisted and dressed the wound when he was done. By Wednesday afternoon, Gary had a clean wound bed, an appropriate moist wound dressing, and a care plan that was clinically sound on paper. Cabrolles Regional, like every Critical Access Hospital in the United States, operates under a CMS requirement to maintain an annual average length of stay of ninety-six hours or less per patient.² Mr. Lane's case had no acute complication. There was no clinical reason to keep him beyond his initial recovery, and no regulatory room to do so even if there had been.
He was discharged Wednesday evening.
The regional durable medical equipment (DME) supplier — a small operation that doubled as the local healthcare supply store and was partially owned by his home health agency — did not have his orders specified. The substitute his home health nurse used was reasonable, but not identical. His home health authorization covered visits every three days; daily wound care was not reimbursable. The nearest wound clinic capable of repeat sharp debridement was ninety miles away, and the first available appointment was eighteen days out.
By the time anyone saw the wound bed again, the slough had reaccumulated, and this time not as passive debris. Research published earlier this month makes clear that slough is a biologically active inflammatory environment, dense with proteases, proinflammatory cytokines, and microbial elements that actively delay healing.³ Gary's wound wasn't waiting for the next appointment. Gary's wound was aggressive, and there was nobody in the care loop to fight back.
By week six, he had crossed the 30-day threshold that distinguishes acute wounds from chronic ones.⁴
Nobody made a clinical mistake. Dr. Blackwell did the work he had done for twenty-three years. Nurse Carter did the work her certification and facility's policies allowed. Every individual in the chain did the job their training, certification, and available resources permitted.
The wound failed in the spaces between them.
The 2024 Delphi consensus has a name for what happened to Mr. Lane. When adequate blood supply is present for wound healing — when, by every clinical measure, the wound should close — but the healthcare system does not have the required resources to support that closure, the consensus framework recognizes that the wound has been converted from healable to maintenance status. It is no longer a healable wound. It has become a maintenance wound.¹
Gary's wound didn't fail.
The system around it converted it.
What "Integral Debridement" Actually Means
In wound care, the phrase for what should have happened after Mr. Lane left the hospital is integral debridement.
A 2024 consensus published in the Journal of Wound Care defined integral debridement as "a synergistic and individualized approach that uses multiple debridement techniques, such as an initial, more aggressive primary technique followed by an adjunctive and continuous debridement technique."⁵ The definition matters because it names something the field has been moving toward for years without quite formalizing: that the moment a surgeon, physician, or appropriately certified clinician removes nonviable tissue from a wound bed is not the end of debridement. It is, at best, the beginning of it.
What Dr. Blackwell did at Gary Lane's bedside on Wednesday morning was the primary intervention: sharp debridement to bleeding tissue, the gold-standard first step for a wound like Gary's. What was supposed to follow was the continuous, adjunctive work of keeping the wound bed clean and biologically receptive to healing.
That ongoing work is the integral part of integral debridement: autolytic dressings, removal of newly accumulated slough, monitoring for early tissue deterioration, and adjustments to the dressing strategy as the wound changes over time.
A peer-reviewed article published this month in WoundSource by Dot Weir, RN, CWON, CWS, and Lindsay Kalan, PhD, put the shift in the clearest possible terms: "One of the most important shifts in modern wound care is the move away from episodic intervention toward continuous wound bed preparation."³ That is not industry marketing language. It is a peer-reviewed description of where modern wound care practice has been heading: away from isolated procedures and toward continuous wound bed management.
The molecular biology supports the framing. Slough — the soft, devitalized tissue that reaccumulates in a wound bed between debridements — is no longer understood as inert debris. Recent work published in Wound Repair and Regeneration characterized slough as a biologically active environment rather than inert debris. Researchers identified collagen fragments, fibrin, extracellular matrix proteins, neutrophils, proteases, microbial elements, and proinflammatory cytokines associated with prolonged inflammation.⁶ When slough reaccumulates in an unmaintained wound bed, the wound is not deteriorating passively. It is being actively held in an inflammatory phase by its own composition. The clinical task is not to wait for the next debridement appointment. The clinical task is to continuously prevent the reaccumulation that converts a healable wound bed into a non-healing one.
Which is precisely the work Mr. Lane's healthcare system could not sustain between the day Dr. Blackwell discharged him from Cabrolles Regional and the day, eighteen days later, someone next examined his foot.
When the Surgeon Isn't Down the Hall
The detail in Mr. Lane's case that hospital administrators should sit with longest is not what went wrong. It is what went right.
Cabrolles Regional had a surgeon on the medical staff who could do a bedside sharp debridement and had the clinical judgment to handle the wound at the level of care it required at admission. Cabrolles Regional had a WOCN who covered the entire facility — credentialed, competent, working within her scope under her facility's policies. That combination, at a twenty-five-bed Critical Access Hospital in rural Texas, is not the baseline. It is the better-than-average version.
Recent workforce data suggest the surgeon-less rural facility is the baseline rather than the exception. American College of Surgeons workforce analysis documented that 60% of rural counties in the United States were without surgical care as of 2019.⁷ For patients in those settings, presenting with a wound requiring sharp debridement may require transfer before that intervention is even possible.
The pipeline is also shrinking. At rural hospitals facing closure risk or service-line downgrades, general surgeon supply has been documented to decline by as much as 8.3% annually.⁸ The Dr. Blackwells of rural American medicine are retiring faster than many systems can replace them.
This is the gap the international wound care consensus was written to address. The 2024 Delphi consensus on wound bed preparation in resource-limited settings defined its operative category broadly: "low resource availability; lacking or restricted funding; remote, isolated, or rural settings... healthcare settings that may have challenges accessing supplies, equipment, specialists, and advanced wound care competencies and skills." The consensus authors were explicit on a point that should not be lost on American readers: "Low-resource settings can be present anywhere in the world and are not limited to lower-income or developing countries."¹
The CAH in rural Texas where Mr. Lane received care is a resource-limited setting under that definition. The CAH in rural Mississippi where another patient presented yesterday is a resource-limited setting under that definition. The CAH in rural Montana where a third patient will present tomorrow is a resource-limited setting under that definition. The consensus is not describing a foreign clinical reality. It is describing the operational baseline of a significant portion of American rural healthcare.
The consensus also acknowledges, in plain language, what the operational baseline means for debridement specifically. Statement 5A allows that active sharp surgical debridement of a healable wound "is undertaken with guidance from advanced wound care expertise only. If not available, consider conservative (sharp) debridement."¹ The consensus framework assumes that advanced wound expertise will often be unavailable and builds adapted protocols around that reality. Mr. Lane's case did not require that adaptation at admission — Cabrolles had Dr. Blackwell. But the consensus framework recognizes that most rural American patients are not so fortunate, and that the standard of care must be adjusted for the resources actually present.
The conversion of healable wounds to maintenance wounds in American CAHs is not primarily a story about negligence or undertrained clinicians. It is a story about clinicians and facilities operating within constraints they did not design and cannot, individually, resolve. The wound care nurse who improvises a dressing protocol because the specified product isn't available is not making a clinical error. The home health agency that cannot authorize daily visits is not failing to advocate. The CAH that discharges a patient within the 96-hour average it is required to maintain is not pushing patients out the door. Each is operating within the limits the regulatory and economic architecture permits.
SHS Insight: Shared Health Services partners with hospitals and physician practices to stabilize continuity across fragmented care settings before a healable wound biologically converts into a maintenance wound. In practice, that means supporting clinicians with standardized protocols, documentation guidance, cross-setting coordination, and accessible peer-to-peer expertise in facilities that lack dedicated wound care infrastructure internally.
The question raised by the Delphi consensus framework is not whether rural hospitals can function like a 500-bed medical center in a major metropolitan area. Most cannot, and most never will.
The real question is whether the infrastructure between care settings is intact enough to prevent wound classification conversion: between the CAH and the SNF, between the SNF and home health, between home health and the wound clinic ninety miles away.
For Mr. Lane, it was not.
The Transitions Problem — Where Debridement Strategies Die
The mechanism is not mysterious. The Delphi consensus framework identifies it directly.
Of the thirty-two substatements defining wound bed preparation in resource-limited settings, only one achieved unanimous strong agreement from all forty-one international experts involved in the process. It was not a recommendation about dressings, surgical technique, or advanced technology. It was Statement 10C, under the framework's Healthcare System Change category:
"Establish timely and effective communication that includes the patient and all interprofessional wound care team members for improved healthcare system wound outcomes."¹
Among thirty-two consensus substatements, the only point of unanimous agreement was not a dressing technology, debridement modality, or assessment tool. It was sustained communication across the interprofessional care team, with the patient included over time.
That is the diagnosis the consensus makes. It is also the single hardest deliverable to execute in the current American regulatory environment.
Consider what Mr. Lane's care plan was up against the moment Dr. Blackwell signed his discharge paperwork Wednesday evening. Cabrolles Regional's electronic record did not interface directly with the regional DME supplier's inventory system. The home health agency operated under a separate documentation architecture and a different reimbursement clock. The wound clinic ninety miles away — where Mr. Lane's next sharp debridement appointment was scheduled for eighteen days out — used a third charting system that the CAH had no read access to. Three care settings. Three documentation systems. No shared real-time view of the wound.
This is the architectural reality American wound care is trying to deliver continuous care through. And the architecture is becoming more restrictive, not less.
The CY 2026 Hospital Outpatient Prospective Payment System Final Rule expanded site-neutral payment reductions for outpatient drug administration services delivered in off-campus provider-based departments, while explicitly exempting Rural Sole Community Hospitals — a regulatory acknowledgment that many rural systems already operate near structural fragility.⁹
At the same time, CMS launched the Wasteful and Inappropriate Service Reduction Model, an AI-driven prior authorization program targeting cellular and tissue-based products. WISeR is currently active in six pilot states, including Texas, where Mr. Lane received care.¹⁰
The Medicare Advantage prior authorization environment has tightened in parallel. Kaiser Family Foundation reporting from January 2026 documents an overall Medicare Advantage prior authorization denial rate of 7.7%, with specialized service denials at certain large commercial payers ranging between 12.3% and 12.8%, and Traditional Medicare prior-authorization pilots producing non-affirmation rates as high as 22.9%.¹¹ For patients requiring advanced wound therapies, these denial rates are not abstract. They are the difference between a continuous wound bed preparation strategy sustained across settings and one interrupted by administrative delay
The clinicians involved in cases like Mr. Lane's see the architecture from inside it. In a recent WoundSource roundtable conversation on integral debridement, Allison Lachaine, MN, BScN, who oversees a provincial wound program for a home care agency in Toronto, named the operational reality her field navigates: "We tend to lose a lot in communication with the referrals and we miss a little bit of that care plan."¹² Lachaine was describing Ontario. The principle she named travels.
This is the operational layer where the international consensus and the American regulatory architecture do not currently align.
The consensus framework assumes continuous communication across the interprofessional wound care team. The healthcare infrastructure delivering that care remains fragmented across documentation systems, authorization timelines, reimbursement constraints, and organizational boundaries.
The clinician at the bedside is left to bridge the gap manually, in the time their patient panel allows, using the channels available to them.
There is a final observation worth making about the gap itself.
When clinical researchers attempt to study wound healing trajectories across transitions in care settings — the very phenomenon the Delphi consensus identifies as load-bearing for outcomes — the published literature becomes unexpectedly thin. Studies of multidisciplinary wound teams within single institutions are abundant. Studies following wound trajectories between institutions, however, are not.
The literature gap is itself revealing. The academic community has, by and large, studied what happens inside the institutions willing and able to fund the research.
What Continuous Wound Care Actually Requires
If the conversion of healable wounds to maintenance wounds is the diagnosis, the next question is operational: what does intact infrastructure actually look like in resource-limited American healthcare settings?
The consensus framework identifies three load-bearing requirements: equitable evidence-informed care across patient populations (10A), provider competency adequate to the wounds presenting (10B), and timely communication across the interprofessional team (10C).¹
None of these are novel science or technologically exotic. The international consensus position is that wound outcomes in resource-limited settings depend primarily on equitable care delivery, clinical competency, and sustained coordination across the patient's care trajectory.
The proof-of-concept evidence is well-documented. Research conducted by Dr. David G. Armstrong and colleagues on multidisciplinary "Toe and Flow" wound care teams — integrated programs that combine podiatric surgery and vascular expertise within a coordinated clinical and operational model — has demonstrated reductions in lower-extremity amputation rates of over fifty percent compared with fragmented, single-discipline care.¹³ The clinical interventions delivered by Toe and Flow teams are not, in their individual components, mysterious. The interventions themselves are familiar: integral debridement, vascular assessment, wound bed preparation, systemic disease management, and patient education. These are not unknown techniques withheld from resource-limited settings. What differs is the infrastructure that allows those interventions to be coordinated, sustained, reassessed, and adjusted across the patient's care trajectory.
This is the gap between consensus best practice and operational reality that the conversion problem lives inside. The clinical knowledge already exists. The consensus framework already exists. The outcomes data already exists. What is missing in most resource-limited American settings is the infrastructure that translates the knowledge, the consensus, and the data across a patient's care trajectory and setting boundaries.
The framework the international consensus calls for is not aspirational. It is descriptive. Forty-one wound experts across fifteen countries documented what intact wound care continuity looks like in resource-limited settings. The Toe and Flow outcomes data demonstrate what can happen when that continuity is operationally sustained.
In practice, the distinction is straightforward: the difference between hoping a wound heals after discharge and maintaining enough visibility across settings to intervene before deterioration accelerates.
For Mr. Lane, the system was not positioned. The wound was healable. The clinicians involved were competent. The consensus benchmark — 20% to 40% reduction by week four, closure by week twelve — remained clinically achievable. What was absent was the connective tissue between settings that translates clinical capability into clinical outcome.
There is a version of Mr. Lane's case where the infrastructure is intact.
When the Infrastructure Holds
Mr. Gary Lane walks into the same emergency department on the same Tuesday night. He is still sixty-seven. He still has the same diabetes, the same wound on the bottom of his right foot, the same cane he didn't usually need. Dr. Blackwell still finds his pulses with his fingers before he reaches for a Doppler. Nurse Carter still meets him at admission and assists at the bedside Wednesday morning when Dr. Blackwell performs the sharp debridement. By Wednesday afternoon Mr. Lane still has a clean wound bed, an appropriate moist wound dressing, and a clinically sound care plan.
He is still discharged Wednesday evening. The ninety-six-hour rule has not changed.
What changes is what travels with him.
The dressing strategy initiated at Cabrolles Regional is the dressing strategy the regional DME supplier has been trained on and stocks. The home health nurse arriving for the first scheduled visit does not improvise — she executes a protocol the agency reviewed with the CAH the week the partnership was structured. The wound clinic ninety miles away has read access to the same wound assessment Dr. Blackwell documented at admission. The eighteen-day appointment window has not changed either; the eighteen-day window with maintained wound bed preparation behind it is not the same eighteen-day window. By the time anyone next sees the wound bed in person, the slough has not reaccumulated, because the dressing protocol was sustained continuously through three care settings. By week four, the wound is twenty to forty percent smaller — the benchmark the consensus framework predicted for a wound like Mr. Lane's. By week twelve, it is healed.
The clinicians involved have not done different work. Dr. Blackwell did the debridement he has done for twenty-three years. Nurse Carter did the assessment and dressing within her certification and her facility's policies. The home health nurse did her every-three-days visits. The wound clinic specialist did the follow-up examination at week three.
What changed is that someone owned the spaces between them.
The international consensus framework describes this kind of continuity explicitly. The multidisciplinary outcomes data demonstrates that it is achievable. The operational challenge for resource-limited American healthcare settings is not discovering new wound science. It is building systems capable of sustaining known best practices across fragmented care environments.
Organizations like Shared Health Services operate inside that gap: helping hospitals, physician practices, and post-acute partners coordinate the protocols, communication pathways, and clinical continuity that wound healing trajectories require.
For patients like Mr. Lane, the difference is not theoretical. It is the difference between a wound that remains healable and a wound that becomes chronic because continuity failed before the biology did.
