Wound dressings are materials or products applied directly to a wound to promote healing and protect it from infection. They serve several purposes such as protection from external contaminants, absorption of excess wound exudate (fluid), and promotion of healing while providing comfort. Types of wound dressings vary widely and include gauze dressings, foam dressings, transparent films, hydrocolloid dressings, alginate dressings, hydrogel dressings, and others.

Fig. 1. Traditional wound dressings: gauze transparent films, foam dressings, hydrogels, hydrocolloid, and hydro-conductive dressings1.

This review provides highlights of the various regulatory challenges for the approval and clearance of wound dressing products. The path to regulatory approval and data requirements for wound dressing products can vary widely based on many factors, including the product composition, intended use, primary mechanism of action, and treatment indication. Understanding the different regulatory pathways and requirements necessary for authorization along each path is critical to ensure compliance with applicable guidelines and streamline approval processes.

Medical Device or Medicinal Product?

The first challenge is determining whether the product falls under the definition of medical device, medicinal product, or a combination product since a lot of wound dressings are borderline products (those where it is not clear from the outset whether they fall under the MDR or the MPD). This determination can sometimes be complex and depends on the product’s intended mode of action and primary function.

What separates medical device products from medicinal products is the mechanism by which a product exerts its principal intended action. In the case of a medicinal product, the effect is achieved by a pharmacological, immunological, or metabolic mechanism of action, whereas in the case of a medical device, the effective mechanism of action must not be pharmacological, immunological, or metabolic although these mechanisms may assist the device in its function. Medical devices generally achieve their primary intended action through physical, mechanical, or thermal means and they do not typically contain pharmacologically active substances that exert a therapeutic effect like medicines do.

Wound dressings primarily function by providing a physical mode of action that manages the micro-environment of the wound to support the natural healing process and are well accepted as medical devices. For example, the wound dressing may provide a physical barrier, absorb exudate, maintain a moist environment, or protect the wound from external contaminants.

Determining the primary intended action is crucial and is typically described in the manufacturer’s labeling and claims, supported by state-of-the-art scientific data specific to the device.  Determination is made on a case-by-case basis and plays a vital role in the device’s classification. Factors taken into account include the device’s intended use, mechanism of action, and how it achieves its therapeutic effect.

It’s important to note that some advanced wound dressings or those containing medicinal substances may require additional regulatory considerations.  For example, if wound dressings contain a medicinal ingredient, such as chlorhexidine, where the principal intended action is to provide a local antimicrobial effect, it will be a medicinal product. On the other hand, solutions incorporating substances with ancillary action, e.g. preservatives, remain a medical device.

Some wound dressings may contain both medical device components (e.g., physical structure, absorbent materials) and medicinal product components (e.g., active ingredients, drugs). These are classified as combination products.

Products that straddle the borderline between medical devices and medicinal products may face challenges in classification, as regulations for each category vary significantly in terms of testing requirements, approval processes, and ongoing monitoring. Manufacturers should follow updated guidance documents such as the guidance document released by the Medical Device Coordinating Group to support manufacturers in qualifying borderline products (MDCG 2022-5).Top of Form

Classification of wound dressings

Another challenge involves the classification of wound dressing products based on risk into Class I, IIa, IIb, or III devices. This classification depends on factors such as their intended use, invasiveness, duration of contact with the body, and potential associated risks. For instance, simple wound dressings like non-adherent gauze pads, bandages, and adhesive bandages that do not penetrate the skin are categorized as Class I. Hydrogel dressings designed to manage the micro-environment of superficial wounds that do not breach the dermis are classified as Class IIa, while those intended for wounds that breach the dermis fall under Class IIb.

Verification and Validation of Wound Dressing

Verification and validation (V&V) are critical processes in the development and regulatory approval of wound dressings These processes are planned based on a thorough risk assessment approach. Key potential risks associated with wound dressing devices include:

1. Adverse Tissue Reaction: Ensuring that the materials used in the dressing do not cause allergic reactions or irritation to the patient’s skin or wound site.

2. Delays in Wound Healing: Verifying that the dressing supports and accelerates the wound healing process rather than delaying it.

3. Incompatibilities with Other Therapies: Assessing compatibility with concurrent therapies or medications that may interact adversely with the dressing materials or components.

4. Infection: Testing for the dressing’s ability to prevent microbial contamination and infection at the wound site.

5. Loss of Barrier Function: Ensuring that the dressing maintains its barrier function to protect the wound from external contaminants.

6. Microbial Growth Within the Product: Preventing microbial colonization or growth within the dressing itself, which could lead to infection.

7. Product Degradation During Shelf Storage: Evaluating the stability and durability of the dressing over its shelf life, including factors like temperature sensitivity and packaging integrity.

8. Retention of Dressing Material in Wound: Verifying that the dressing does not leave residues or particles that could impair wound healing or cause discomfort.

These risks guide the specific V&V tests conducted during the development of wound dressings. The selection of test methods is determined by factors such as the type of device, the duration and nature of body contact, and the intended use. Each test aims to mitigate these risks and ensure that the dressing meets the safety, efficacy, and performance standards required for regulatory approval.

For wound dressings, verification involves confirming that the product specifications, materials used, manufacturing processes, and other design elements align with the intended design requirements. This may include testing the physical properties of the dressing, performance, and characterization testing, absorbency, permeability, microbial testing, and biocompatibility.

Validating a wound dressing involves assessing its performance under real or simulated conditions that replicate its clinical use. This includes testing for effectiveness in managing exudate, promoting wound healing, preventing infection, antimicrobial efficacy clinical performance testing, and ensuring patient safety. Validation also considers factors such as shelf-life stability, usability, and compatibility with other medical treatments.

The Changing Regulatory Environment

Another aspect is to constantly be aware of recent updates and guidelines since regulations are continually evolving. Recent updates include the transition from MDD to MDR represents a shift towards more stringent regulation and oversight of wound dressings, to ensure higher levels of patient safety and device performance across the European market. Key changes and implications include stricter requirements and increased emphasis on clinical evidence and post-market follow-up.

Updates in the US include the introduction by the FDA of new proposed rules aimed at classifying previously unclassified wound dressings and liquid wound washes containing antimicrobials. These rules would categorize products based on their level of antimicrobial resistance (AMR) concern. Products with a high level of AMR concern would fall under class III medical devices, necessitating Premarket Approvals (PMAs), while those with medium or low levels of concern would be classified as class II devices. These proposed rules, when become effective, will impact both existing commercially available devices in this category and future products.

Manufacturers of wound care products incorporating antimicrobials or other chemicals should analyze their products to determine if they could be affected by these proposed rules. They should also assess their regulatory status under the new classification to ensure that their current marketing authorization remains adequate. Additionally, companies may need to update their product labeling and review their marketing claims to align with the new regulatory requirements, as failure to do so could result in their products being reclassified as combination products or drugs.

In summary, different regulatory pathways, with varying degrees of data and regulatory oversight, can be used to achieve market authorization for wound dressing products. Navigating these regulatory requirements requires a thorough understanding and adherence to applicable guidelines to ensure the safety and efficacy of wound and skin care before placing products onto the market. In addition, the specific regulations may vary depending on the country or region and it is recommended to consult with regulatory authorities or seek professional advice to ensure compliance with specific regulations in the relevant country or region.

This post is dedicated to young startups and small companies currently facing numerous challenges, more than ever before. From our experience, we have, unfortunately, learned that during crises, there is often a tendency in young companies to neglect regulatory and quality issues. This is done to accelerate product development and meet investor timelines, under the belief that these matters can be addressed later. However, bypassing essential development stages and neglecting coherent documentation may lead to future difficulties, especially during regulatory submission.

Therefore, we have summarized a concise list of things you shouldn’t compromise on now, to ensure minimal investment when seeking regulatory approval later:

1. Intended use and Indications for use:

Define early on the official description that outlines the purpose for which the product is intended, including its medical function, conditions of use, types of diseases or medical conditions it addresses, and the intended user population. This definition is critical for the regulatory process as it determines the regulatory pathway, impacts clinical requirements guides the verification and validation testing of the product.

This task appears relatively simple, but in reality, it is not so. The Intended Use must be defined based on a deep understanding of the market and medical use, alongside regulatory expertise.

Additionally, it is crucial to consider medical reimbursement options, where alignment with both regulatory approval and reimbursement is necessary.

One common and crucial mistake among startup companies is attempting to define the regulatory classification and pathway of their device on their own, despite having no regulatory expertise, to save money. This can be a costly mistake that may result in significant expenses and time delays later when seeking regulatory approval. It is highly advised to invest the money and hire an expert to develop the regulatory strategy for you – defining the product classification, predicate device (for the US), main V&V tests, clinical aspects, and main QMS requirements for your product and of course the main stages for regulatory submission. The regulatory strategy shall be market-specific.

Another common mistake among startup companies or small firms is assuming that upon regulatory approval, they can immediately start selling the product. In reality, there indeed are companies that received FDA or CE approval but failed to penetrate the market because the product lacks medical reimbursement or an attractive sales channel.

2. Device description:

While it may seem self-explanatory, device description is a critical definition that sets the intentions and boundaries of product development. It must correspond with the intended use, and describe how the product will archive it. It’s important to specify what the product does, its features, design specifications, materials used, functional capabilities, operating principles, and any relevant performance characteristics. Additionally, it may include information on indications for use, contraindications, warnings, precautions, and instructions for use to ensure safe and effective use of the device in clinical settings.

The device description is not marketing material but more of an official statement of the company regarding its product. This will be used as the basis for regulatory submissions and labeling.

Marking materials will be based on the intended use and the device description as they are approved by the regulators. Therefore, it should be done carefully, and taking into account both marketing and regulatory aspects.

Unfortunately, we’ve seen more than once a startup that failed to define an accurate device description and as a result faced many inconsistencies and confusion, especially between what is presented to investors or in the marketing materials and what is permissible under regulation.

3. Risk management:

Besides being a mandatory requirement in most regulations, early-stage (during the planning of the design and development) risk management according to ISO 14971 allows for identifying potential hazards. This early identification enables to define the required verification and validation testing (including the necessity and the scope of pre-clinical and clinical trials) and make corrections and improvements to the product design before costly testing and validation begin.

For risk management to be beneficial in an early stage, more than the product’s design, EMC and SW should be considered. We suggested evaluating the risks of the manufacturing process and user-related form the beginning.

Manufacturing Process- when designing a device, the methods of its manufacturing should weigh into the design. Specially, if the product requires any special process or environmental conditions. For example, if you design a sterile finale product that has a built-in buttery, you will need to identify specific risks inherent in the sterilization of a buttery, and consider materials for the proper sterilization and design the product and its packaging to mitigate the identified risks.

In that matter, scaling up the manufacturing process might raise unexpected process risks, especially for products that require special technologies or specific knowledge. When identified early, the manufacturer might be able to avoid the pain of redesigning the product to scale up the manufacturing process.

User-related risks – once the intended user and environment are determined, risks related to user information perception, cognition, and actions should be identified. Then, when designing the product, you should consider possible controls for these risks.

Specifically, medical device reprocessing by the user may raise a lot of concerns and risks. Reprocessing of medical devices should be as simple and straightforward as possible for the user. When designing with such intention, you should be careful to identify who will conduct the reprocessing and what is their technical understanding (medical care professional? technician? layperson?). Equally important is to identify the environment for the reprocessing process. These considerations have a major effect on the required device’s durability, appearance, how its disassembled or connected, and more.

It important to understate that risk management is not a document but a continuous process that spans the entire product’s lifetime. The earlier it is initiated, the more accurate, comprehensive, and ultimately beneficial it will be.

4. Verification and Validation (V&V) planning:

Planning and conducting V&V activities early in the development phase, guided by risk analysis, are essential for regulatory compliance and product quality assurance. But, for young companies and startups, in ultimately important for budget planning.

Planning V&V early and documenting it systematically can help identify connections between processes, requirements, and tests, potentially saving on expensive laboratory trials later. Mapping required V&V tests also anchors budget management due to their high costs.

While planning the V&V tests, it is critical to conduct a thorough study of the applicable regulations, standards, and guidelines for your device.

5. Adherence to proper development stages and documentation:

Documenting milestones in product development, including version differences and actions taken for each version is crucial even for small teams. Clear documentation ensures consistency and facilitates a comprehensive understanding of project progress, particularly when managing tight deadlines and concurrent tasks.

It’s important to note that the above list outlines only the topics that are not recommended to be neglected even in difficult situations. This list is the bare minimum, and additional quality and regulatory requirements will be required depending on the market you intend to target. Of course, ideally, the development of the product should go hand in hand with quality and regulatory requirements.

4. Device Rejection: Both caregivers and patients may abandon difficult-to-use devices, leading to poorer health outcomes.

Regulatory Landscape:

Regulatory requirements worldwide mandate that medical devices undergo rigorous design, testing, and monitoring to ensure they are safe, effective, and user-friendly. Integrating human factors throughout the development process, conducting thorough usability testing, and documenting these activities are essential components. Post-market surveillance further monitors device usability in real-world settings to continually improve patient safety and device effectiveness.

The FDA’s Human Factors and Usability Engineering Guidance outlines expectations for incorporating human factors into device design and development. While not legally binding, this guidance reflects the FDA’s current perspective and serves as a valuable resource for manufacturers aiming for regulatory approval. Compliance with FDA recommendations is crucial as industry standards evolve, ensuring devices meet usability expectations and enhance patient care.

Under the EU MDR, similar stringent requirements are binding in Europe. Manufacturers must integrate usability engineering into the entire device lifecycle, perform systematic usability evaluations, and manage usability-related risks effectively.

ISO 62366 helps put these requirements into practice by providing a structured approach to Usability Engineering. The standard guides manufacturers in integrating usability considerations across the device lifecycle, including defining and evaluating user needs and risks.

Adhering to FDA guidance, MDR requirements, and ISO standards not only facilitates regulatory compliance but also demonstrates a commitment to producing safe, effective, and user-friendly medical devices that improve healthcare outcomes globally.

Conclusion:

Usability in medical devices is no longer peripheral; it’s a scientific imperative for ensuring patient safety, treatment efficacy, and regulatory compliance. Prioritizing user-centered design principles can foster improved patient outcomes and streamline regulatory approval processes.
