What is Software as a Medical Device (SaMD)?
Software as a Medical Device (SaMD) refers to software that is intended to be used for medical purposes on its own, without being part of a hardware medical device. In other words, SaMD is software that functions as a medical device and is designed to perform medical functions without being tied to a specific piece of hardware.
Annex-XVI refers to a category of products that are subject to specific regulations and directives to ensure their safety, quality, and environmental impact. These products cover a wide range of industries, including medical devices, construction products, machinery, electrical equipment, and more. The purpose of Annex-XVI is to safeguard the health and safety of consumers, as well as the environment.
CE marking is a mandatory requirement for Annex-XVI products sold within the European Economic Area (EEA). It indicates that a product has undergone the necessary conformity assessment procedures and meets the essential health, safety, and environmental protection requirements set out by the European Union (EU). CE marking provides assurance to manufacturers, distributors, and end-users that the product is safe and compliant with applicable regulations.
Key characteristics of Software as a Medical Device include:
- Independent Functionality: SaMD operates as a standalone software application or program, independent of any particular hardware medical device. It is designed to achieve its intended medical purpose without being an integral part of a physical device.
- Medical Purpose: SaMD is intended for use in the diagnosis, prevention, monitoring, treatment, or alleviation of disease or injury. It may also be used for the investigation, replacement, modification, or support of the anatomy or of a physiological process.
- Regulatory Oversight: SaMD is subject to regulatory oversight to ensure its safety, effectiveness, and compliance with relevant medical device regulations. In the European Union, SaMD is regulated under the EU Medical Device Regulation (MDR) or In Vitro Diagnostic Device Regulation (IVDR), depending on its classification.
- Wide Range of Applications: SaMD encompasses a wide range of applications, including medical imaging software, health information systems, clinical decision support tools, monitoring applications, and other software intended for medical purposes.
- Risk Classification: SaMD is classified based on the level of risk it poses to patients and users. The risk classification determines the regulatory requirements and level of scrutiny applied to the software during the conformity assessment process.
- Conformity Assessment: Manufacturers of SaMD are required to perform a conformity assessment to demonstrate that the software meets the essential requirements for safety and performance. This includes clinical evaluation and performance evaluation.
Examples of Software as a Medical Device include:
- Diagnostic software: Software used for the interpretation of medical images or laboratory test results.
- Clinical decision support systems: Software providing recommendations to healthcare professionals based on patient data.
- Monitoring and alerting software: Software used for continuous monitoring of physiological parameters and issuing alerts in case of abnormalities.
- Health information systems: Software managing and processing patient health records for healthcare providers.
CE marking process for Software as a Medical Device (SaMD)
The regulatory framework for SaMD is outlined in the EU Regulation 2017/745 on Medical Devices (Medical Device Regulation or MDR) and the EU Regulation 2017/746 on In Vitro Diagnostic Medical Devices (In Vitro Diagnostic Device Regulation or IVDR)
Here are key points regarding the CE marking for Software as a Medical Device:

2. Medication Management Apps:
- Applications that help users manage medication schedules, provide dosage reminders, and offer basic information about medications.
3. Clinical Decision Support Software (Limited Scope):
- Software providing guidance to healthcare professionals based on specific data inputs, but with a moderate level of complexity.
Class IIb: Medium to High Risk SaMD
1. More Complex Clinical Decision Support Software:
- Software offering advanced clinical decision support for healthcare professionals, covering a broader range of medical conditions and requiring a higher level of complexity.
2. Diagnostic Imaging Software (Non-Critical):
