Introduction
The term “Software as a Medical Device” (SaMD) is defined as software intended to be used for one or more medical purposes that perform these purposes without being part of a hardware medical device.
In the healthcare industry, software is becoming more and more essential and popular. Software developed for medical purposes (software used to make clinical decisions) and non-medical purposes (administrative, financial) is being used in healthcare due to the availability of a multitude of technology platforms (e.g., personal computers, smart phones, network servers, etc.) as well as the increasing ease of access and distribution (e.g., internet, cloud).
Three key changes to the regulatory framework were proposed as part of the consultation
- Classify SaMD products according to the potential harm they could cause to patients;
- Requiring SaMD to be included in the ARTG- Changes to exclude SaMD products from the personal importation exceptions and require them to be included in the Australian Register of Therapeutic Goods (ARTG) and will require an Australian sponsor; and
- Changes to the essential principles- include clear and transparent requirements for demonstrating the safety and performance of SaMD and other regulated software
Decision Steps for qualification of Software as MDSW
The qualification of MDSW, either as a device or an accessory, is independent of the software’s location or the type of interconnection between the software and a device. There are few steps for the qualification of MDSW
- There is a lack of harmonization between different regulatory bodies (e.g. FDA, MHRA, and EU MDR) as they define and categorize “Software as a Medical Device” (SaMD) differently.
- This changes the regulatory scope, and for companies wanting to place products on global markets, this can be complex to navigate.
- Cybersecurity, ensuring compliance while utilising third-party software, and enabling software updates without compromising device operation or compliance are some additional difficulties.
- International bodies such as the International Medical Device Regulators Forum (IMDRF) and Global Medical Device Nomenclature (GMDN) are working towards improving convergence and harmonization between different countries.
Software meant to be used for medical purposes that isn’t an component of a hardware medical device is referred to as Software as a Medical Device (SaMD). These software applications are becoming increasingly prevalent in healthcare, offering a wide range of functionalities from diagnostic support to treatment management. However, their regulation poses several challenges due to their unique characteristics. Here are some of the regulatory challenges in SaMD:
- Classification and Risk Management: SaMD products vary widely in complexity, functionality, and risk. Classifying them appropriately and managing associated risks can be challenging. Regulatory bodies such as the FDA (Food and Drug Administration) in the United States and the European Commission in Europe have developed frameworks for risk-based classification, but determining the appropriate risk level for a given SaMD can still be complex.
- Rapid Technological Advancements: “Software as a Medical Device” (SaMD) technologies often evolve rapidly, introducing new features and functionalities. Regulatory frameworks must be flexible enough to accommodate innovation while ensuring patient safety and efficacy. However, keeping regulations up-to-date with the pace of technological advancement can be a significant challenge.
- Interoperability and Data Security: Many SaMD products rely on interoperability with other healthcare systems and devices to function effectively. Ensuring seamless integration while maintaining data security and privacy presents regulatory challenges. Regulatory bodies need to establish standards and guidelines for interoperability and data security in SaMD.
- Evidence Generation and Clinical Validation: Demonstrating the safety, efficacy, and clinical utility of SaMD products requires robust evidence generation and clinical validation processes. However, traditional clinical trial methodologies may not always be suitable for evaluating software-based interventions. Regulatory agencies are exploring innovative approaches to evidence generation, such as real-world evidence and adaptive clinical trials, but these approaches bring their own challenges.
- International Harmonization: SaMD developers often need to navigate multiple regulatory frameworks when seeking market approval in different countries or regions. Achieving international harmonization of regulatory requirements can streamline the approval process and reduce barriers to market entry. However, differences in regulatory approaches and standards across jurisdictions make harmonization challenging.
- Post-market Surveillance and Monitoring: Ensuring ongoing safety and effectiveness of SaMD products once they are on the market is crucial. Establishing robust post-market surveillance and monitoring systems is essential for detecting and addressing safety issues and ensuring continuous improvement. However, implementing effective post-market surveillance programs can be resource-intensive and challenging for SaMD developers.
Addressing these regulatory challenges requires collaboration among regulatory agencies, industry stakeholders, healthcare providers, and other relevant parties. It also requires ongoing dialogue and adaptation to keep pace with the evolving landscape of “Software as a Medical Device” (SaMD) technologies and healthcare practices.

Challenges in SaMD Regulation
- Rapid Technological Evolution: SaMD evolves at a pace much faster than traditional medical devices, posing challenges for regulatory bodies to keep up with novel technologies while ensuring safety and efficacy.
- Interpretation of Regulations: Regulatory bodies often struggle to interpret existing regulations to accommodate the unique characteristics of SaMD, leading to ambiguity and inconsistency in approval processes.
- Data Privacy and Security: SaMD often deals with sensitive patient data, raising concerns about privacy and security. Regulatory compliance with data protection laws such as GDPR in the EU adds another layer of complexity.
- Clinical Evidence Requirements: Unlike traditional medical devices, SaMD may lack established clinical evidence due to its novelty. Establishing robust clinical evidence to demonstrate safety and efficacy can be challenging and time-consuming.
- International Harmonization: Discrepancies in regulatory requirements across different regions can hinder global market access for “Software as a Medical Device” (SaMD) developers, necessitating efforts towards international harmonization.
Key Points to be remembered
- Apply medical device definition to software based on Intended Use and criteria specified.
- Key IMDRF guidance and ISO standards provide help with interpretation and adoption of SaMD in the regulatory framework.
- QMS controls and lifecycle management are essential (e.g. ISO 13485 and IEC 62304). Implement Design QMS processes early in the software development life-cycle.
- Must consider data security and privacy requirements (HIPPA, GDPR, SOC, etc) and reimbursement requirements. Level and type of Clinical Evidence should be based on the significance of information provided by the SaMD.
- Continuous post-market monitoring and responding to changes is required (cybersecurity, platform changes, changes to third party software etc.)
