The healthcare equipment market is rapidly changing. In addition to the conventional hardware-based products, including implants, diagnostic devices, and surgical instruments, Digital Health and Software as a Medical Device (SaMD) solutions are currently assuming a vital role in the provision of healthcare. These are mobile health applications, clinical decision-support programs, AI-based diagnostics, and cloud-based monitoring systems.
Although the ISO 13485 is taken as the world standard of medical devices quality management system, the way it is applied to digital health and SaMD is quite different from the way it is applied to standard medical devices. This blog explores the differences between ISO 13485 for digital health and SaMD.
The ISO 13485 aims at implementing a quality management system that would provide medical equipment to meet customer and regulatory demands. In the case of the traditional medical devices, compliance is to a great extent associated with the design of the physical product, manufacturing controls, and hardware certification.
In the case of digital health and SaMD organizations, the device, however, is the software. This significantly alters the interpretation, implementation, and audit of ISO 13485 requirements.
The traditional medical devices tend to follow a linear development life cycle. After the design, validation, and release of a product, changes become relatively sparse.
Conversely, SaMD products and digital health tend to be developed using either agile or iterative development patterns, where:
The ISO 13485 SaMD puts more focus on the software lifecycle management as it can ensure that design controls are maintained within the dynamic development environments.
In the case of hardware, validation is conducted on physical performance, durability, and safety tests. In SaMD, validation focuses on:
The auditors require strong evidence that the software is working as expected in all the scenarios of the intended use.
Conventional equipment is usually associated with a mechanical failure risk or material defect. The dangers of digital health and SaMD include:
Digital health ISO 13485 works closely with the software risk management process, which involves the unceasing realization, assessment, and reduction of the hazardous situations associated with software.
Harmless mechanical equipment rarely considers cybersecurity an issue. For SaMD, it is central. Auditors look at the way organizations:
This renders the implementation of ISO 13485 on SaMD more interdisciplinary.
There is a tendency to change traditional medical device documentation gradually. Digital health organizations need to have living documentation that changes with:
The ISO 13485 imposes vigorous document control in order to provide traceability between the requirements, changes in code, validation outcomes, and risk controls.
The auditors emphasize greatly on traceability matrices that connect:
This traceability level can be quite complicated for SaMD, compared to hardware-based devices.
The conventional methods of medical equipment make use of periodic post-market surveillance. In digital health and SaMD solutions, there is a tendency to create real-time usage records, error records, and performance records.
Digital health ISO 13485 requires organizations to use this data actively to:
This makes it more of a continuity post-market responsibility in contrast to conventional devices.
The dependence of SaMD organizations is usually on:
Audits by ISO 13485 on digital health assess the control, monitoring, and quality of these dependencies. Traditional medical device manufacturers usually find this type of supplier less complex.
| Area | Traditional Medical Devices | Digital Health and SaMD |
| Product Nature | Physical hardware | Software-based |
| Development Model | Linear, staged | Agile, iterative |
| Risk Focus | Mechanical and material risks | Software, data, and clinical logic risks |
| Validation | Physical and performance testing | Functional and clinical validation |
| Cybersecurity | Minimal | Critical requirement |
| Documentation | Mostly static | Continuously evolving |
| Post-Market Activities | Periodic | Ongoing and data-driven |
ISO 13485 auditors of digital health and SaMD consider more than the conventional controls in manufacturing. They evaluate the efficiency of organizations in integrating the principles of quality management in rapidly evolving software settings without damaging patient safety or regulatory adherence.
Companies perceiving SaMD to be similar to a traditional appliance tend to have a hard time at audit because of the weaknesses in the lifecycle management, documentation oversight, and risk management.
The ISO 13485 for Digital Health and SaMD is a radically different approach to software-based products than the use of ISO 13485 on more traditional medical equipment due to the continuous evolution of software-based products, the nature of risks involved, and the importance of data integrity and cybersecurity. Implementing a quality management system that will help in maintaining control, traceability, and patient safety is the key to successful implementation. To overcome these differences and create quality systems that meet the expectations of both innovation and regulation, working with experienced certification bodies like Blue Wolf Certifications will be beneficial.
Yes. The ISO 13485 is used with Software as a Medical Device, where the software lifecycle, risk control, and validation controls are given special attention.
Yes, but the agile processes should be embedded with solid documentation, traceability, and risk controls to fit the ISO 13485 requirements.
