Description
FIELD OF THE INVENTION

The present invention relates to the field of human factors engineering, specifically to an AI-enhanced framework for successful application of human factors and usability engineering in the development of safe, effective, and user-friendly medical devices and other healthcare systems and products. The invention represents an intelligent, end-to-end adaptive system that optimizes the human factors process throughout the product development lifecycle, carefully aligning with regulatory standards and best practices.


DESCRIPTION OF THE RELATED ART

Human factors engineering (HFE) focuses on optimizing the interactions between humans and products or systems they use, with the goal of improving safety, usability, and overall effectiveness. In the life sciences sector, where precision, accuracy, and user safety are paramount, effective application of HFE principles is essential. Ensuring medical devices are intuitive, drug packaging is accessible, and healthcare technologies facilitate efficient clinical workflows leads to successful adoption of these products.


As technology continues to advance and innovations drive the evolution of life sciences products, the integration of HFE principles in the development of medical devices and healthcare systems has become increasingly more critical in recent years. Regulatory bodies, such as the U.S. Food and Drug Administration (FDA), have recognized the importance of HFE in ensuring the safety, effectiveness, and usability of medical devices, as evidenced by the publication of the “Applying Human Factors and Usability Engineering to Medical Devices” guidance in 2016 [2].


However, the implementation of HFE in the medical device development industry has been accompanied by numerous challenges and shortcomings. Research conducted in this field has revealed significant issues that hinder the successful execution of HF validation projects and the achievement of regulatory compliance, hindering also innovation and patient safety [1] [4] [3].


Other initially identified challenges were a lack of comprehensive framework tailored to HF requirements, to foster alignment and standardization of best practices. For instance, conflicting feedback from regulatory bodies such as the FDA, coupled with the lack of clear guidelines on critical elements like user group identification, training protocols, study design, data utilization across regions, and aspects like Instructions for Use (IFU) validation and equivalency, significantly amplify the complexity of compliance and operational consistency. HFE encounters obstacles related to complexity, time efficiency, alignment, and regulatory compliance. [4]


Key stakeholders, including manufacturers and human factors service providers, often struggle to effectively integrate HFE into their processes. Challenges in aligning with regulatory expectations and seamlessly incorporating HFE activities into product development workflows can lead to suboptimal outcomes, such as delays, product redesigns, and medical devices that are not fully safe and effective, potentially causing patient harm and product recalls.


A staggering 96% of HFE submissions to the FDA are rejected due to deficiencies, indicating a pressing need for improvement in HFE practices. These deficiencies may include incomplete risk analysis, inadequate user groups, incorrect user training approach, and insufficient consideration of human factors during design and validation phases. [3], [4].


Traditionally, HFE solutions have focused on providing valuable insights into user interactions and product usability, critical aspects (such as objectivity, consistency/standardization, process maturity, and continuous improvement) have been neglected. There is a need for systematic solutions that provide stakeholders with the necessary tools to enhance quality, HFE process maturity levels, set benchmarks, ensure standardization and consistency, which will also enable alignment with quality management systems (QMS) regulations when it comes to HFE [5] [8].


Initial Solution: To address the discussed gaps so far, the Successful Human Factors 2.0 (SHF 2.0) framework was developed [6]. SHF 2.0 is comprehensive maturity model based on key success factors, structured methodologies, best practices, and regulatory alignment. The framework provides a foundation for successful application of HFE in MedTech product lifecycle, aiming to ensure alignment with QMS needs [8], standardization through its maturity component key categories of best practices, metrics, and a common language (See FIGS. 1 and FIGS. 2). Validation of the framework further proved the urgent need for standardization of identified best practices and key success factors [7].


Whereas the SHF 2.0 framework offers a valuable foundation for improving HFE practices and addressing critical gaps, it has limitations in fully addressing the dynamic and complex nature of the life sciences industry. Significant challenges persist, including stakeholder resistance, regulatory complexity, and limitations in scalability and adaptation to evolving industry trends and technologies. Moreover, traditional HFE approaches lack the sophistication required to meet the needs of rapidly evolving life sciences products and healthcare systems.


While the core standards initially integrated within the SHF 2.0 framework provide a robust base, the dynamic nature of medical device development often necessitates the incorporation of specific regulatory requirements for each targeted region. Additional and continuously updated standards and guidelines tailored to specific project needs and regional requirements may be a continuous pressure, such as for instance, the newer human factors guidance from the FDA which adds the human factors submission categorization [9].


The previous simply highlights the evolving nature of this field, and any potential solution must account for that). Additionally, collaboration mechanisms that ensure easy cooperation among stakeholders, including regulatory bodies, are still crucial for optimized and standardized HF reviews.


Furthermore, the manual nature of traditional HFE approaches often results in inefficiencies, scalability issues, and potential biases, which can hinder the effectiveness of the HFE process. Not to mention the extensive use of resource and need for efficiencies and more cost-effective solutions.


In summary, as a standalone solution, the SHF 2.0 framework does not provide the necessary scalability, adaptability, and dynamic data processing required to keep pace with the rapidly evolving regulatory landscape and the increasing complexity of medical devices and healthcare systems. As technology continues to advance and the complexity of healthcare products increases, traditional HFE approaches will continue to face significant challenges in keeping pace with evolving user needs, regulatory requirements, and industry best practices. There is a pressing need for a more advanced, technology-driven approach to human factors optimization.

Interestingly, the converse—leveraging AI to enhance and optimize HFE processes—had been unexplored up to the present disclosure.


HFE benefits tremendously from AI-enabled capability to address the previously discussed challenges as well as the many limitations of traditional HFE methods.
