    Device Description

    Silver Hydrofiber® Reinforced with Nylon Wound Dressings is a soft, sterile, non-woven flat dressing composed of hydrocolloid fibers (sodium carboxymethylcellulose), that is reinforced with nylon stitching and that contain 1.2% ionic silver which allows for an average of 12mg of silver for a 4 inch x 4 inch dressing. The silver in the dressing kills wound bacteria held in the dressing and provides an antimicrobial barrier to protect the wound bed. This dressing absorbs high amounts of wound fluid and bacteria and creates a soft, cohesive gel that intimately conforms to the wound surface, maintains a moist environment and aids in the removal of nonviable tissue from the wound (autolytic debridement). The moist wound healing environment and control of wound bacteria supports the body's healing process and helps reduce the risk of wound infection.

    AI/ML Overview

    This document is a Premarket Notification (510(k)) for a medical device – a wound dressing. While it discusses the device's indications, substantial equivalence to a predicate device, and the general safety and effectiveness, it does not contain the specific details of a study that establishes acceptance criteria and then proves the device meets those criteria.

    The document states:

    "Extensive clinical testing, including controlled GCP studies, has been carried out with AQUACEL® Ag (the predicate). The results of these studies have consistently demonstrated that the products are safe and effective dressings in the treatment of a wide range of wound types. ... See 510(k) #K080383 for details."

    And also:

    "...extensive clinical investigations with Silver Hydrofiber® Dressings Reinforced with Nylon were not considered necessary to confirm the clinical safety and performance for all indications, however, a single study has been carried out in partial thickness burns, which is anticipated to be the major indication for this product..."

    Therefore, I cannot provide the requested information in the format of a table detailing acceptance criteria and reported device performance from this document because it is not present. The document defers to a previous 510(k) (K080383) for the predicate device's studies and mentions a single study for the current device without providing its details.

    To answer your request, I would need access to the K080383 submission and/or the details of the "single study...carried out in partial thickness burns" referenced in K090254.

    AI/ML Overview

    Based on the provided text, the document is a 510(k) Summary for the AQUACEL® Ag with Hydrofiber® Silver Impregnated Antimicrobial Dressing and AQUACEL® Hydrofiber® Wound Dressing. This type of regulatory submission demonstrates substantial equivalence to a legally marketed predicate device, rather than proving that the device meets specific acceptance criteria through a newly conducted study with detailed statistical analysis.

    The document discusses clinical studies, but these are literature reviews of existing studies on the predicate device (AQUACEL® Hydrofiber® Wound Dressing) or similar Hydrofiber® technology, used to support the safety and effectiveness for new indications or the new device (AQUACEL® Ag). It does not present a new, dedicated study designed to explicitly meet pre-defined acceptance criteria for the current 510(k) submission in the way one might assess a high-tech diagnostic algorithm.

    Therefore, many of the requested categories for a study proving device acceptance criteria cannot be directly answered from this regulatory summary. However, I can extract the relevant information that is present.

    Here's a breakdown of what can be inferred or explicitly stated:

    1. Table of Acceptance Criteria and Reported Device Performance

    This document does not present explicit acceptance criteria or target device performance values in a table format for a specific new study to demonstrate device capabilities against defined metrics. Instead, it relies on the established safety and effectiveness of the predicate device and the literature.

    The "performance" is reported in terms of clinical outcomes from existing studies, showing the benefits of Hydrofiber® dressings.

    Performance Metric (Based on Literature Review)Reported Device Performance (AQUACEL® / AQUACEL® Ag)ComparatorStatistical Significance / Effect Size
    Likelihood of no wound complications5.8 times more likely to result in no complicationsControl95% CI 2.8-12.5; p<0.00001
    Dressing pain scoreStatistically lowerControlp<0.001

    Other benefitsFewer dressing changes, less mechanical irritation/damage to woundConventional dressingsNot quantified in text.
    Antimicrobial barrier (AQUACEL® Ag)Kills wound bacteria held in dressing, protects wound bed, reduces risk of infection.Not directly compared in this summary for Ag version, but inferred from silver impregnation.Qualitative statement.

    2. Sample Size Used for the Test Set and Data Provenance

    The "test set" here refers to the patient cohorts involved in the summarized clinical trials, which are part of a literature review rather than a new standalone validation study for this 510(k).

    • Study 1 (Ravenscroft et al.): 183 patients (85 patients randomized to AQUACEL® / Tegaderm™, 98 patients to control).
    • Study 2 (Abuzakuk et al.): 61 patients (30 patients allocated to AQUACEL® hydrofiber dressing group, 31 patients to control group).
    • Study 3 (Harle et al.): 100 hip replacement patients (50 patients randomized to AQUACEL® hydrofiber dressing, 50 patients to control).

    Data Provenance: The studies are clinical trials, implying prospective data collection. The countries of origin are not explicitly stated, but the journal publications cited (Ann R Coll Surg Engl; Int Wound J; Journal of Orthopedic Nursing) suggest an international origin, likely including the UK (Ann R Coll Surg Engl), given the author names.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts

    This question is not applicable in the context of wound care dressing clinical trials. "Ground truth" in this scenario would typically be established by clinical assessments made by healthcare professionals (e.g., surgeons, nurses) managing the patients in the trials, following established medical protocols for wound assessment and treatment. The document does not specify the number or qualifications of clinicians involved in making these assessments for the referenced studies.

    4. Adjudication Method for the Test Set

    The document describes the studies as "randomized controlled trials." This implies a systematic approach to patient assignment, but it does not specify any particular adjudication method (e.g., 2+1, 3+1) for evaluating outcomes. Outcomes were likely assessed by treating clinicians or independent researchers involved in the respective studies based on clinical measures (e.g., wound complications, pain scores, dressing change frequency).

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    This question is not applicable. The device is a wound dressing, not an AI-powered diagnostic or assistive technology for human readers. Therefore, an MRMC study or AI assistance is irrelevant to this submission.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

    This question is not applicable. The device is a physical wound dressing and does not involve an algorithm.

    7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

    The ground truth or clinical endpoints for the summarized studies were based on outcomes data directly observed in patients, such as:

    • Wound complications (e.g., presence/absence of complications)
    • Patient-reported pain scores
    • Frequency of dressing changes
    • Observations of blister formation, hematoma, and edema

    These are clinical outcomes directly measured or observed in patients during the course of their treatment.

    8. The Sample Size for the Training Set

    This question is not applicable. The device is a wound dressing, not a machine learning algorithm that requires a training set. The clinical data summarized are for demonstrating safety and effectiveness for regulatory clearance, not for training an AI model.

    9. How the Ground Truth for the Training Set was Established

    This question is not applicable, as there is no training set for a wound dressing.

    Device Description

    AQUACEL® dressing is a soft, sterile, non-woven pad or ribbon dressing composed of hydrocolloid fibers (sodium carboxymethylcellulose).

    AI/ML Overview

    Here's an analysis of the acceptance criteria and study information for the AQUACEL® Hydrofiber® Wound Dressing, based on the provided text:

    Acceptance Criteria and Device Performance for AQUACEL® Hydrofiber® Wound Dressing

    Unfortunately, the provided text does not explicitly state quantitative acceptance criteria for pain reduction. The studies described are comparative, aiming to show that AQUACEL® performs equally well or better than other dressings in terms of pain management. Therefore, the "acceptance criteria" are implied to be demonstrating comparable or superior performance to existing wound dressings.

    1. Table of Acceptance Criteria and Reported Device Performance:

    Acceptance Criteria (Implied)Reported Device Performance (AQUACEL®)
    Pain on Dressing Change:
    - Comparable/Superior to Kaltostat® for leg ulcersLeg Ulcers (Study 1): 76% no pain, 20% mild pain, 3% moderate pain on dressing change (Kaltostat®: 83% no pain, 13% mild pain, 4% moderate pain) - Comparable
    - Comparable/Superior to Alginate for leg ulcersLeg Ulcers (Study 2): 65% no pain, 16% mild pain, 3.4% moderate pain on dressing removal (Alginate: 62% no pain, 14% mild pain, 4% moderate pain) - Comparable
    - Superior to Saline Gauze for pressure ulcersPressure Ulcers (Study 3): 82% rated dressing removal as excellent or good (54% excellent, 28% good) (Gauze: 24% excellent or good (7% excellent, 17% good)) - Superior
    - Comparable/Superior to Alginate for acute surgical woundsAcute Surgical Wounds (Foster, et al.): 92% no or mild pain at first dressing change; 84% pain-free on post-operative day 7 (Alginate: 80% no or mild pain at first dressing change; 58% pain-free on post-operative day 7) - Superior
    - Superior to Paraffin Gauze for split-thickness donor sitesSplit-Thickness Donor Sites (Barnea, et al.): Significantly lower pain scores at all evaluation points (p-values 0.0001 (day 1) to 0.03 (day 15)) - Superior
    - Superior to Silver Sulphadiazine for partial-thickness burnsPartial-Thickness Burns (Kogan, et al.): At 30-min assessment: pain reduced to 6.1 (AQUACEL®) vs 6.9 (Silver Sulphadiazine) on day 1-2; pain reduced to 5.2 (AQUACEL®) vs 5.6 (Silver Sulphadiazine) on day 5. Authors concluded superior pain relief.
    Pain while Dressing in situ:Explicit quantitative data for "pain while dressing in situ" is not extracted as readily as "pain on dressing change." The studies generally support the claim that the gelling action "reduce wound pain while the dressing is in situ." The superior pain relief during dressing changes implies better patient comfort overall.
    Non-traumatic Removal:Implied by "ease of removal" and "without damaging newly formed tissue" due to gel formation. The pain reduction during removal directly supports this.
    Moist Wound Environment:Implied by Hydrofiber® technology forming a "clear, cool gel on contact with wound exudate."
    Patient Comfort:Generally supported by reductions in pain during wear and removal.

    2. Sample Sizes Used for the Test Set and Data Provenance:

    Study/ReportSample Size (Test Set)Data ProvenanceTest Set Description (if applicable)
    ConvaTec Studies:
    1. Leg Ulcers (moderately/heavily exudating)44 patientsProspective, controlled, randomized; ConvaTec study (manufacturer-sponsored). Location not specified, but ConvaTec is a US company.21 managed with AQUACEL®, 23 with Kaltostat®. Mean age 68.1 years, 82% venous etiology, 89% shallow ulcer depth, median duration 10 months.
    2. Leg Ulcers (multicenter)40 patientsProspective, controlled, randomized; ConvaTec study (manufacturer-sponsored). Location not specified.20 managed with AQUACEL® (269 dressing changes), 20 with alginate (227 dressing changes). Majority male (80%), average age 63 years.
    3. Pressure Ulcers (Stage III/IV)85 patientsProspective, controlled, randomized; ConvaTec study (manufacturer-sponsored). Location not specified.43 with AQUACEL® (536 dressing changes), 42 with moist saline dressing/gauze (500 dressing changes). Moderately or heavily exudating.
    Published Reports:
    1. Acute Surgical Wounds (Foster, et al.)100 patientsProspective, randomized, controlled; published in peer review journal. Location not specified.Randomized to receive either AQUACEL® or alginate dressing.
    2. Split-Thickness Donor Sites (Barnea, et al.)23 adult patientsProspective, comparative; published in peer review journal. Location not specified.Each patient used both AQUACEL® and paraffin gauze, with half the donor site covered by each.
    3. Partial-Thickness Burns (Kogan, et al.)22 patientsProspective; published in peer review journal. Location not specified.11 patients treated with AQUACEL®, 11 with silver sulphadiazine. Patients aged 1.5 to 41 years.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

    The ground truth for pain assessment in these studies is primarily patient-reported pain scores (e.g., "no pain, mild pain, moderate pain," "analogue scale," "visual analogue scales") and, in one instance, observation of behavior for non-verbal children.

    The text does not specify a number of "experts" used to establish ground truth in the traditional sense (e.g., radiologists interpreting images). Instead, the patients themselves provided the primary data for pain perception. Clinicians involved in the studies would have been healthcare professionals managing wounds, but their role was in administering the treatments and collecting patient data, not acting as independent adjudicators of the "truth" of pain.

    4. Adjudication Method for the Test Set:

    There is no explicit mention of an adjudication method (like 2+1 or 3+1 consensus) for the "test set" in the context of pain assessment. As noted above, the "ground truth" for pain is directly reported by the patient. For observational assessments (e.g., for non-verbal children), the text doesn't specify if multiple observers were used or if a consensus method was employed. The studies are described as "controlled" and "randomized," indicating rigorous design for comparing treatments.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

    Based on the provided text, there is no MRMC comparative effectiveness study described for human readers improving with AI vs. without AI assistance. The device is a wound dressing, and the studies focus on its clinical performance in pain management, not on AI-assisted diagnostic or interpretative tasks.

    6. Standalone (Algorithm Only) Performance:

    This question is not applicable as AQUACEL® is a physical wound dressing and not an algorithm or AI-powered device.

    7. Type of Ground Truth Used:

    The primary type of ground truth used is patient-reported outcomes, specifically:

    • Subjective pain assessment: Rated by patients as "no pain, mild pain, moderate pain," or using "analogue scales" and "visual analogue scales."
    • Behavioral observation: For non-verbal children, pain was assessed by observation of behavior.

    8. Sample Size for the Training Set:

    The provided text does not describe a "training set" in the context of machine learning or AI. The studies are clinical trials comparing the dressing's performance against other dressings or standard care. Therefore, there's no distinction between a "training set" and "test set" in the AI sense for this product. The sample sizes mentioned above (e.g., 44, 40, 85 patients in ConvaTec studies, 100, 23, 22 in published reports) represent the total patient cohorts for these clinical performance studies.

    9. How Ground Truth for the Training Set Was Established:

    As there is no "training set" in the AI sense, this question is not applicable. The ground truth for pain assessment in the clinical studies was established directly from patient reporting or observation, as described in point 7.

    For over-the-counter use, Absorbent Antimicrobial Wound Dressing may be used for minor abrasions, lacerations, minor cuts, minor scalds and burns.

    Under the supervision of a health care professional, Absorbent Antimicrobial Wound Dressing is an effective barrier to bacterial penetration, which may help reduce infection in partial thickness (second degree) burns, diabetic foot ulcers (venous stasis ulcers, arterial ulcers and leg ulcers of mixed aetiology) and pressure ulcers/sores (partial & full thickness), surgical wounds left to heal by secondary intent, traumatic wounds, wounds that are prone to bleeding such as wounds that have been mechanically or surgically debrided and oncology wounds with exudate such as fungoides-cutaneous tumors, fungating carcinoma, cutaneous metastasis, Kaposi's sarcoma and angiosarcoma.

    Absorbent Antimicrobial Wound Dressing may be used on minimally exuding, non-exuding and dry wounds as stated in the DIRECTIONS FOR USE.

    Device Description

    Absorbent Antimicrobial Wound Dressing is composed of sodium carboxymethylcellulose and ionic silver. In contact with wound exudate, the highly absorbent dressing creates a soft, cohesive gel that forms an intimate contact with the wound surface and maintains a moist woundhealing environment.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a medical device called "Absorbent Antimicrobial Wound Dressing." This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the device meets specific acceptance criteria through a clinical study with detailed performance metrics.

    Therefore, many of the requested sections regarding acceptance criteria, study design, sample sizes, expert ground truth, and comparative effectiveness studies are not applicable or available in this document. The submission relies on comparative bench testing and biocompatibility testing to establish substantial equivalence.

    Here's a breakdown of the available information:

    1. A table of acceptance criteria and the reported device performance

    This information is not provided in the document. The 510(k) process for this device focuses on demonstrating substantial equivalence to a predicate device rather than meeting specific quantifiable performance criteria against a predefined standard. The document mentions "comparative bench testing" and "biocompatibility testing," but does not detail the acceptance criteria or specific performance results from these tests in a table format.

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    This information is not provided in the document. The document mentions "comparative bench testing" but does not specify the sample sizes or data provenance (country of origin, retrospective/prospective). It also mentions "biocompatibility testing."

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    This information is not applicable or provided. For bench testing and biocompatibility testing, "ground truth" as it relates to expert consensus for diagnostic or prognostic devices is not relevant. The ground truth for such tests typically relies on established laboratory standards and measurement protocols rather than expert human interpretation.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    This information is not applicable or provided. Adjudication methods are typically relevant for studies involving human interpretation or clinical endpoints, not for bench testing or biocompatibility testing as described.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    This information is not applicable or provided. The device in question is a wound dressing, not an AI-powered diagnostic or assistive technology. Therefore, an MRMC study or evaluation of human reader improvement with AI assistance is not relevant.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    This information is not applicable or provided. The device is a wound dressing, not an algorithm. Standalone algorithm performance is not relevant.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    For the biocompatibility testing, the ground truth would be established through laboratory standards and measurements as defined by relevant ISO or ASTM standards for biocompatibility (e.g., cytotoxicity, sensitization, irritation indices).

    For the comparative bench testing, the ground truth would be based on physical and chemical measurements comparing the Absorbent Antimicrobial Wound Dressing's properties (e.g., absorbency, silver release) against those of the predicate device (Acticoat™ Silver Coated Wound Dressing) using defined laboratory protocols. The document does not specify what specific parameters were measured or how ground truth for those parameters was established, other than implying standard laboratory methods.

    8. The sample size for the training set

    This information is not applicable or provided. The development of a wound dressing does not typically involve a "training set" in the context of machine learning. The product development would involve iterative design, formulation, and testing, but not a training set as understood in AI systems.

    9. How the ground truth for the training set was established

    This information is not applicable or provided, as there is no "training set" in the context of this traditional medical device submission.

    2. Sample Size Used for the Test Set and Data Provenance:

    The provided document does not describe a "test set" in the context of an algorithm or AI system evaluation. This submission is for a physical medical device (wound dressing), and its clearance is based on substantial equivalence to predicate devices and biocompatibility testing, not on clinical performance data in a "test set" as understood for AI/ML devices. Therefore, these categories are not applicable.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:

    Not applicable. As above, there is no "test set" or "ground truth" establishment for an algorithm in this submission.

    4. Adjudication Method for the Test Set:

    Not applicable.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

    Not applicable. This is not an AI/ML device.

    6. Standalone (Algorithm Only) Performance:

    Not applicable. This is not an AI/ML device.

    7. Type of Ground Truth Used:

    Not applicable in the context of an algorithm. For the physical device, the "ground truth" or basis for acceptance relies on:

    • Predicate Device Equivalence: The established safety and effectiveness of the legally marketed predicate devices.
    • Biocompatibility Standards: Pre-defined standards for biological safety testing of medical devices.

    8. Sample Size for the Training Set:

    Not applicable. This is not an AI/ML device.

    9. How the Ground Truth for the Training Set Was Established:

    Not applicable. This is not an AI/ML device.


    Summary for the HA Absorbent Wound Dressing (K984388):

    This submission is for a physical medical device (a wound dressing), not an AI/ML-driven device. As such, the concept of "acceptance criteria" and "study" as typically applied to AI performance (e.g., sensitivity, specificity, F1-score on a test set) is not directly applicable.

    The "study" in this context refers to biocompatibility testing and the comparison to predicate devices to demonstrate substantial equivalence and safety. The acceptance criteria for clearance were primarily based on:

    • Demonstrating the HA Absorbent Wound Dressing is substantially equivalent to legally marketed predicate devices (FIBRACOL Collagen-Alginate Wound Dressing and Knitted Wound Dressing) in terms of materials, intended use, and fundamental function.
    • Passing a series of biocompatibility tests to ensure the material is safe for its intended use (non-toxic, non-hemolytic, negligible irritant, non-cytotoxic, 0% sensitization potential).

    The FDA's decision letter (K984388) confirms the device's substantial equivalence and outlines specific labeling limitations, which effectively become part of the modified acceptance criteria for its marketing.

    Intended Use

    Knitted Wound Dressing Standard, WCL and Ribbon can be used in the management of acute and chronic wounds, including diabetic ulcers. The design of Standard makes it suitable for shallow or cavity wounds and Ribbon as a packing strip for cavity wounds, fistulae and sinuses.

    Device Description

    Knitted Wound Dressing is a sterile gelling gauze. The warp (fibers running top to bottom) consist of viscose yarn, while the wefts (fibers running left right) are a co-spun alginate and viscose.

    AI/ML Overview

    The provided text describes a 510(k) Premarket Notification for a "Knitted Wound Dressing." This document focuses on demonstrating substantial equivalence to predicate devices based on intended use, design, and performance through comparative bench testing and biocompatibility testing. It is not a study proving device performance against specific clinical acceptance criteria, especially not for an AI/ML device.

    Therefore, the requested information regarding acceptance criteria, study details, sample sizes, expert involvement, adjudication, MRMC studies, standalone performance, ground truth, and training data is not applicable to this document.

    Here's why and what information can be extracted:

    1. A table of acceptance criteria and the reported device performance:

    • Acceptance Criteria (Implied): The acceptance criteria for this type of medical device submission (510(k)) are primarily focused on demonstrating "substantial equivalence" to a legally marketed predicate device. This means the new device must be as safe and effective as the predicate.
    • Reported Device Performance: The document states:
      • "Comparative bench testing was conducted on the Knitted Wound Dressing versus its substantially equivalent products. Test results show the products to be equivalent."
      • "Knitted Wound Dressing has been subjected to biocompatibility testing utilizing the ISO 10993 Part I 'Biological Evaluation of Medical Devices' with FDA modified matrix (Guidance effective July 1, 1995). The results of this testing demonstrate that Knitted Wound Dressing is considered to be non-sensitizing, non-toxic, non-hemolytic and a negligible irritant."

    The following numbered items (2-9) are not applicable to this document because it describes the regulatory clearance of a physical medical device (knitted wound dressing), not an AI/ML-based diagnostic or prognostic tool that would typically involve such studies.

    The document details a regulatory submission for a physical medical device. The "study" mentioned is "comparative bench testing" and "biocompatibility testing," which are laboratory-based tests comparing the physical properties and safety of the new wound dressing to existing ones. It does not involve patient data, expert interpretations, or AI/ML algorithms.
