Research report
A research report is the sourced material a domain
dossier is synthesized from — generated on a plan and a cadence, one topic per file.
A report carries no confidence tags. Its bracketed markers say who might have
an incentive to shade a line; none of them says anyone checked it. To reach a score, a line has
to be drafted onto a candidate as unverified and pass the Verifier or the
Corroborator, like everything else.

Sourcing: Seven single-source, mostly peer-reviewed findings on companion-animal cost
The domain dossier's §3 already lays out the five user-group rows and flags two open gaps: no source separates veterinary-technician incentives from veterinarian incentives specifically for NPWT, and no source addresses clinic-side margin on a rented or purchased NPWT system. Neither gap closes in this pass — no device-specific literature exists for either — so this report instead works the surrounding structural economics that shape how each user group would receive any capital-equipment adjunct in this space: client cost sensitivity and its effect on prescriber behavior, veterinary-technician workforce strain, general small-animal pricing opacity, the thinness of the private pet-insurance market, and one revealed-behaviour data point on how insurance status changes real treatment decisions for costly surgical care in dogs. Every quantity below rests on exactly one source and carries that marker; none of it is NPWT-specific, and each line says so.
_Baseline (v1). No prior version; this establishes the starting point for future diffs._
A 2017 JAVMA cross-sectional survey of 1,122 US and Canadian small-animal practitioners (37,036 surveyed) found that 57% (620/1,088) reported client economic limitations affected their ability to provide desired care on a daily basis, and 49% (527/1,071) reported moderate-to-substantial burnout, with client economic limitations cited as a contributing factor. Only 31% of respondents routinely discussed veterinary costs with clients before a pet became ill, and only 23% routinely discussed pet insurance, with lack of time given as the reason for skipping both [single-source] [1]. That is the closest published measure of how a prescriber's incentive to recommend an added-cost adjunct (an NPWT device, versus continued bandaging) is already constrained by a client's ability to pay, independent of the device's own evidence.
A separate 2025 JAVMA modeling paper forecasting companion-animal veterinary labor markets to 2035 found "no statistically significant or consistent differences in either supply or demand growth" and stated the data "do not support an expectation of a continued shortage" in the US companion-animal veterinarian labor market, contrary to prior studies it cites [single-source] [2]. This bears on prescriber availability/bandwidth for adopting an adjunct technology and cuts against the popular "vet shortage" framing for the companion-animal side specifically — it says nothing about equine.
A 2026 JAVMA paper on structured onboarding states plainly that "workforce shortages and turnover among credentialed veterinary technicians impose substantial operational and financial costs on veterinary practices" and that "veterinary technician-specific transition-to-practice research remains limited" [single-source] [3]. No quantified turnover rate specific to US credentialed veterinary technicians was independently retrieved this pass — a widely repeated 23-25% annual turnover figure attributed to AAHA could not be traced to a retrievable AAHA primary document (aaha.org returned HTTP 403 on every attempt) and is not used here. The dossier's own §3 vendor-support finding (a paid line item for "seals, leaks, and dressing construction") is the only device-adjacent operator signal in this domain and is not repeated here as new.
A 2026 cross-sectional study of 177 US small-animal veterinary clinics (157 with a website) found only 3 clinics (1.91%, 3/157) published specific service pricing online, only 7 (4.46%) offered a "Wellness Plan," and only 2 (1.27%) mentioned insurance options on their sites [single-source] [4]. This is general small-animal pricing opacity, not wound-care- or NPWT-specific, but it is directly relevant to how a purchaser would even encounter or compare a price for an adjunct device before a treatment decision is made.
No federal or near-universal private payer for veterinary devices exists, consistent with the dossier's own §6 finding. Where insurance exists, it measurably changes spending: a 2020 US study using logit models on a dog-owner sample found pet health insurance "had a significant and positive impact on the amount spent at the veterinarian" [single-source] [5].
The dossier's §9 records "would owners pay several hundred dollars out of pocket for an adjunct veterinary NPWT device" as an unanswerable class-3 question with no available twin. The closest revealed-behaviour twin found this pass is not wound-specific: a retrospective study of 260 dogs with gastric dilatation-volvulus (GDV) across 24 US emergency clinics over a 2-year period found a pre-surgical euthanasia rate of 10% in insured dogs versus 37% in uninsured dogs (p<0.001); adjusted for age, deposit size, comorbidities and blood lactate, lacking insurance increased the odds of pre-surgical euthanasia by a factor of 7.4 (95% CI 2.0–37; p=0.002), and 80% of insured versus 53% of uninsured dogs survived to discharge (p<0.001) [single-source] [6]. GDV is an acute abdominal emergency, not a distal-limb wound, and this is not evidence about wound-care spending specifically — it is evidence that, for a different costly surgical condition in the same species, insurance/cost status measurably changes whether treatment is pursued at all rather than whether a specific device is chosen.
A 2021 US choice-experiment survey of 306 uninsured dog owners found 44% willing to spend up to $1,000 and 46% willing to spend $3,000 or more to prolong their pet's life by a year, and average willingness to pay $24/month more for a preventive-care insurance feature after being shown treatment-cost and disease-risk information (pet insurance uptake itself rose 12.3% after that information was presented) [single-source] [7]. This is a stated-preference survey about insurance and life-extension generally, not a device-purchase decision, and is reported here as published survey content, not as this report's own answer to what an owner would pay.

Well established: Nothing in this report rests on ≥2 independent, non-affiliated primary sources — every line above is a single finding from a single source, marked as such. The structural fact that no federal or near-universal private veterinary payer exists is not re-derived here; it is the dossier's own §6 finding (independently sourced there to 21 CFR 807.65 and the connector-blindness argument) and is only referenced, not re-established, by this report.
Thin: All seven lines in §3 are [single-source] — none upgraded to plain fact by this report regardless of how authoritative the single source is. A widely repeated 23-25% veterinary-technician turnover figure attributed to AAHA was deliberately not used because no retrievable AAHA primary document could be reached this pass to check it against. Two findings this pass would otherwise have reported — a Brakke-Consulting-attributed corporate-consolidation percentage sourced only to a secondary pets.care page, and NAPHIA's 2026 State of the Industry Report figure for US pet-insurance penetration — were dropped rather than cited, because neither source carries a resolvable identifier (a PMID, an NCT number, a K-number, a CFR section, an HCPCS code, a DOI, a CELEX number, or an FR Doc number) that a reader could independently verify; a URL to a market-research page or PDF is not sufficient on its own. A third dropped finding, a 2022 EquiManagement trade-press account of AAEP equine-workforce attrition, was removed for the same reason.
Rescoped from class 3: "Would owners pay several hundred dollars out of pocket for an adjunct veterinary NPWT device?" (dossier §9, recorded there as having no available twin) was not answered here either, but this pass located a partial revealed-behaviour analog: "what fraction of dogs facing a different costly, acute surgical condition (GDV) are euthanized before surgery rather than treated, and does insurance status change that fraction?" — answered in §3 [6]. It is a partial twin, not a full one: GDV is a different condition from a distal-limb wound, and the underlying decision (treat-vs-euthanize for an acute emergency) is not the same decision as (add an adjunct device to an already-planned wound treatment). "Would veterinary surgeons or technicians adopt an NPWT-specific device over their current option?" was not asked or answered here, consistent with the dossier's own §9 treatment of the same question.
Out of scope: CPT descriptors, veterinary claims/EHR datasets, and a PatentsView-backed patent search were not attempted in this pass — none bears directly on user-group incentives and all three are already named out-of-scope in the domain dossier for other sections.
Not searched vs. not found: A quantified US veterinary-technician turnover/attrition rate from a primary AAHA source was searched for (web search and a direct aaha.org fetch attempt) and not found — the page returned HTTP 403 (Incapsula-style bot mitigation), consistent with this repo's known aaha.org/avma.org access limitation. A primary AVMA report quantifying corporate-consolidation share of US veterinary practices was similarly attempted (avma.org/news/veterinarians-report-increasing-price-sensitivity-decreasing-visits) and not retrieved — HTTP 403/blocked on every attempt, including a direct curl fetch with an alternate user agent. An AAVMC PDF projecting veterinarian/technician supply and demand to 2032 was fetched as a binary but its text could not be extracted with the tooling available this pass and is recorded as not retrieved, not as a finding. Equine-specific owner insurance/cost-decision literature was searched for directly (connectors literature, "horse owner insurance cost veterinary treatment decision economic") and returned zero PubMed records — recorded as found-and-negative for that specific query, not as unsearched. A NAIC 2019 "Regulator's Guide to Pet Insurance" white paper was retrieved and read in full as a candidate substitute for the dropped NAPHIA penetration figure; it carries no PMID, DOI, CELEX, CFR, or FR Doc identifier of its own (its only registry-style identifier, "Ch. 896," names a California statute reproduced in its appendix, not the NAIC document itself) and its own penetration data is nine years stale (2017), so it was not substituted in. No NPWT-specific, wound-care-specific, or distal-limb-specific user-group source was found for either species in any search this pass; every source in §4 is a general veterinary-economics finding applied by analogy, and that analogy is not evidence of the specific device-adoption behavior it stands in for.
