Wound care experts evaluate whether the assessment, prevention, staging, treatment, and documentation of a wound met the accepted standard of care, and — critically — whether a wound that developed was avoidable. The staging framework itself is usually the first battleground. The National Pressure Injury Advisory Panel classification distinguishes Stage 1 (intact skin with localized non-blanchable erythema), Stage 2 (partial-thickness loss of epidermis and dermis presenting as a shallow open ulcer), Stage 3 (full-thickness loss with visible adipose tissue but no exposed fascia, muscle, or bone), and Stage 4 (deep full-thickness loss with exposed or palpable muscle, tendon, ligament, or bone), along with deep tissue injury and unstageable categories 1. Misstaging in the chart — recording a deep tissue injury as a Stage 1, or a Stage 3 as a Stage 2 — is a recurring point of dispute, and it often carries downstream consequences for what care was ordered.
The legal standard in the long-term care setting is unusually explicit. Federal regulation at 42 CFR 483.25(b)(1) requires that, based on a comprehensive assessment, a facility ensure that a resident "receives care, consistent with professional standards of practice, to prevent pressure ulcers and does not develop pressure ulcers unless the individual's clinical condition demonstrates that they were unavoidable," and that a resident with pressure ulcers "receives necessary treatment and services, consistent with professional standards of practice, to promote healing, prevent infection and prevent new ulcers from developing" 2. That regulation effectively places the burden of explaining unavoidability on the facility, and it is why the avoidable-versus-unavoidable analysis is the center of gravity in nearly every pressure injury case.
The underlying epidemiology explains why these cases recur. Pressure injuries affect up to three million American adults annually; prevalence in acute care runs roughly 10% to 18% and exceeds 25% among critically ill patients, and about two-thirds occur in adults aged 70 and older 1. In the acute setting, the Centers for Medicare & Medicaid Services operates a Hospital-Acquired Conditions program that ties payment to conditions acquired during an inpatient stay, which means hospitals maintain their own present-on-admission coding, incidence tracking, and prevention program documentation — records that are ordinarily obtainable in discovery 3. AHRQ's hospital pressure ulcer prevention toolkit supplies a widely referenced statement of what a functioning prevention program looks like, including risk assessment on admission and at intervals, skin inspection, repositioning, support surface selection, nutrition, and moisture management 4.
Beyond pressure injuries, wound care experts address diabetic foot ulcers and the offloading, debridement, vascular assessment, and infection-control decisions that precede a major amputation; venous and arterial leg ulcers and the compression-therapy decisions that govern them; surgical site infection and wound dehiscence; burns; skin tears and moisture-associated skin damage; and the appropriateness of advanced modalities such as negative pressure wound therapy, cellular and tissue-based products, and hyperbaric oxygen. In amputation cases the analysis typically turns on the timing of vascular referral and revascularization, whether osteomyelitis was diagnosed and treated, and whether the patient was ever offloaded in a way that could have permitted healing.
Credentialing in wound care spans several disciplines, and matching the expert to the defendant matters. The American Board of Wound Management certifies the CWCA, CWS, and CWSP designations, each requiring at least three years of wound care experience 5. The Wound, Ostomy and Continence Nursing Certification Board certifies nurses in wound, ostomy, and continence care, in foot care, at the advanced practice level, and as Wound Treatment Associates 6. A case against a nursing facility is usually best served by a certified wound care nurse who can speak to bedside assessment, turning schedules, and documentation, while a case involving surgical debridement, revascularization, or amputation typically requires a physician expert alongside.
Federal regulation requires that a nursing facility resident "does not develop pressure ulcers unless the individual's clinical condition demonstrates that they were unavoidable" — which is why the avoidable-versus-unavoidable question sits at the center of nearly every pressure injury case.

FAQ
A qualified expert should hold wound care certification through the American Board of Wound Management or the Wound, Ostomy and Continence Nursing Certification Board and be in active practice in a setting comparable to the one at issue. Discipline should track the defendant: a certified wound care nurse is usually the right expert on bedside assessment, turning schedules, and documentation in a nursing facility, while surgical debridement, revascularization, and amputation questions call for a physician expert.
Wound care experts are retained in pressure injury cases in nursing homes and hospitals, staging and documentation disputes, diabetic foot ulcer and amputation cases, surgical site infection and wound dehiscence claims, and disputes over the appropriateness or billing of advanced wound modalities. They are also engaged to assess damages, including the expected course of healing and long-term care needs.
Federal regulation at 42 CFR 483.25(b)(1) requires that a facility ensure a resident does not develop pressure ulcers unless the resident's clinical condition demonstrates they were unavoidable, and that a resident who has one receives treatment consistent with professional standards. In practice the expert reconstructs whether a risk assessment was performed on admission and repeated appropriately, whether skin was inspected and findings charted, whether repositioning actually occurred as ordered, whether the support surface and nutritional support matched the risk level, and whether the facility's own care plan was followed.
Because staging drives both the care that should have been ordered and the inference about how long the wound went unaddressed. The recognized classification separates Stage 1 non-blanchable erythema, Stage 2 partial-thickness loss, Stage 3 full-thickness loss with visible adipose, and Stage 4 loss with exposed muscle, tendon, or bone, plus deep tissue injury and unstageable wounds. A deep tissue injury charted as a Stage 1, or a Stage 3 charted as a Stage 2, frequently signals both a documentation problem and an undertreatment problem.
Risk assessment scores and their dates, complete skin assessment and wound documentation with measurements and photographs, turning and repositioning records, support surface and specialty bed orders and delivery records, nutrition and dietitian notes, wound care orders and treatment administration records, staffing and assignment sheets for the relevant shifts, and the facility's own prevention policy. In hospital cases, present-on-admission coding and hospital-acquired condition tracking are also relevant given CMS's hospital-acquired conditions program.
In general, medical expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are clinical experience, forensic experience, academic qualifications such as Fellowships, clinical settings, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
