Software as a Medical Device

Evolution of Medical Device Technology

Over the last forty years, there has been a notable upsurge in technological progress in the realm of medical devices, leading to the rise of Software as a Medical Device (SaMD).

Accelerated Progress in Recent Years

In recent times, this progress has experienced a notable acceleration, largely attributed to the widespread adoption of the Internet of Things (IoT) and its associated elements. Elements such as wireless connectivity, cloud computing, artificial intelligence (AI), and the utilization of SaMD have played pivotal roles in this acceleration.

Transformation in Healthcare Services

These innovations have not only revolutionized healthcare processes but also triggered a substantial transformation in the administration and delivery of healthcare services. They have redefined patient care, diagnostics, treatment monitoring, and overall healthcare management. The integration of these technologies has brought about significant improvements in efficiency, accuracy, and accessibility within the healthcare industry.

Understanding the Types of Software for Medical Devices

Software for medical devices can be classified into three main types:

Software as a Medical Device (SaMD)

Medical Device Software (SaMD) is software designed for medical applications, either independently or in combination with a medical device. Its functionalities encompass diagnosing, treating, monitoring, or preventing diseases and conditions. An example of SaMD is software that utilizes artificial intelligence (AI) to analyze medical images and identify conditions such as cancer or other diseases.

Software in a Medical Device (SiMD)

SiMD stands out as a significant category of software designed for medical devices, integrated within the device to ensure its safe and effective functionality. SiMD is responsible for managing the device’s hardware and executing essential functions. For instance, software governing the insulin flow in an insulin pump exemplifies the role of software within a medical device.

Applications employed in the production or upkeep of medical equipment.

Software employed in the creation or upkeep of medical devices serves purposes such as design, development, manufacturing, or maintenance. It is not intended for direct use by patients or healthcare providers. For instance, software utilized in the design of medical devices through computer-aided design (CAD) exemplifies the kind of software involved in the manufacturing or maintenance of medical devices.

How Do You Know If Your Mobile App is a SaMD?

The primary method of categorizing a mobile app as SaMD involves evaluating its intended function. According to FDA guidelines, if an app is used to cure, detect, treat, mitigate, or prevent diseases, it is deemed to be Software as a Medical Device (SaMD).

For instance, a glucose monitoring application that gathers blood sugar level data and stores it in cloud storage falls into this classification. Similarly, an application designed to oversee irregularities in EKG data qualifies as a medical device if its primary purpose is diagnostic.

FDA-approved documentation outlines the key criteria for Software as a Medical Device (SaMD) as follows:

SaMD is considered a medical device and includes certain in-vitro diagnostic (IVD) medical devices.

It is capable of operating on general-purpose (non-medical) computing platforms.

Software does not fall under the SaMD definition if its primary purpose is to operate hardware medical devices.

It can be used in conjunction with other products, such as medical devices.

It can interface with various medical devices, encompassing hardware medical devices, other SaMD software, as well as general-purpose software.

Factors to Consider for SaMD Characterization

Establishing the purpose of SaMD is paramount for its classification. The definition statement serves as the foundation for categorizing SaMD, and the process relies extensively on the information furnished by the software. SaMDs undergo characterization through two distinct methods:

Information conveyed by SaMD includes:

Facilitating patient diagnosis or treatment
Providing insights for clinical management
Guiding clinical management decisions

Health condition :

Critical health condition
Serious health condition
Non-serious health condition

After information is delineated according to the aforementioned characterizations, SaMDs are categorized into four groups, ranging from I to IV.

Understanding the Software As a Medical Device Examples

SaMD represents a form of software that engages with diverse medical devices, encompassing both hardware and software, within clinical and general-use environments. For example, therapy planning software can furnish data to a linear accelerator, subsequently serving as input for another hardware device. This instance underscores the broad spectrum of applications for SaMD.

Yet another example of Software as a Medical Device involves software crafted for analyzing a condition utilizing a tri-axial accelerometer, functioning on the embedded processor within a consumer digital camera. This particular software qualifies as a Medical Device based on its intended capabilities for medical analysis.

Moreover, Software linked to a medical hardware device, yet not essential for the device to fulfill its medical purpose, is classified as Software as a Medical Device and not considered an accessory to the medical device.

Software as a Medical Device (SaMD) can operate on general-purpose computing platforms designed for non-clinical functions. When these software applications are installed on such platforms, they can also be seamlessly integrated into a hardware medical device.

Category Wise Examples of SaMD

As mentioned earlier, the risk-based categories of SaMD, categorized as IV, are elaborated below:

Category IV:

SaMDs that conduct diagnostic image analysis to facilitate treatment decisions during acute stroke episodes.
SaMDs compute the fractal dimension of a lesion and construct a structural map, unveiling distinct growth patterns for diagnostic purposes, and distinguishing between benign and malignant lesions.
Software as a Medical Devices integrates data from immunoassays to screen for mutable pathogens outbreaks that may pose a high risk of contagion.

Category III:

SaMD utilizes the phone’s microphone to identify interrupted breathing patterns during sleep.
It is employed to offer information, such as capturing images, monitoring growth, or collecting additional data, to complement the information used by healthcare providers for diagnosing whether a skin lesion is benign or malignant.

Category II:

SaMDs conducting heart rate analysis.
SaMD utilizes individuals’ health record data to forecast the risks of heart disease or stroke and formulate preventive strategies.
SaMD incorporates and analyzes various tests to provide diagnostic recommendations for specific clinical indications.

Category I:

Medical software devices collect data from symptom diaries to offer insights for assessing the likelihood of an asthma episode.
Medical software devices examining images and eye movement to direct subsequent diagnostic steps for astigmatism.
Software storing historical blood pressure data for healthcare providers’ review.
Software utilizing data on hearing sensitivity, speech in noise, and user responses to questionnaires on typical listening scenarios for self-assessment of hearing loss.
