SaMD Watering Holes: Job Boards & Regional Organizations
The following is the second of a three-blog series on the Validated State. This content builds on ideas first presented by Randy Horton, Bernhard Kappe and Pat Baird of Philips at the AAMI ISC 2021 conference. Orthogonal and industry partners will continue to present on this subject at conferences in 2022. For more details, visit our Events page.

Cloud computing is an ubiquitous tool in modern software. Though MedTech has been slow to adopt the cloud compared to other industries, the benefits that cloud computing provides to any industry’s software products are numerous. The cloud’s on-demand service scales across remotely accessed computers, so as demand increases, computing power increases without driving up costs. The flexibility of the cloud allows software to be updated and deployed at a rapid pace. And firms of any size can use it, bypassing the need for in-house, self-maintained (and costly) servers and data centers.
Third-party cloud providers are constantly reinvesting their profits and effort into improving what makes the cloud so valuable, to the benefit of their user base. But this persistent improvement is a double-edged sword for the MedTech industry. When a developer places their software on the cloud, they are giving up some amount of control of their software to the third-party provider. The environment in which their software runs is subject to updates, rollbacks and changes that providers can make on their schedule, as they constantly improve the security and enhance the functionality of their systems. MedTech developers running software with safety concerns can’t assume they’ll be notified of updates ahead of time – or that they’ll recognize a change after it’s been made.
Relinquishing control can be a frightening prospect for the MedTech industry because it challenges the long-held paradigm of software validation. When medical device software and quality systems are validated, developers are confident they are running as intended, according to industry standards and in line with assurances made to the FDA.
Cloud providers can change the environment on a dime. We don’t have that flexibility; our changes have to be managed according to industry protocols. And when changes to the cloud introduce a bug or compromise our data, we’re in a unique position of potentially doing harm to the patients, clinicians and providers that use and prescribe our software. Software as a Medical Device (SaMD) is not going to achieve everything it could for improving patient outcomes if we cannot get past this issue. We need to find the sweet spot of taking advantage of the obvious benefits of cloud technology while mitigating risks.
At Orthogonal, we’ve pioneered the adoption of modern software development techniques in our industry. We’re pro-cloud – generally and for medical devices. In addition to over a decade of working on medical devices, our legacy includes developing cloud-based software within a year of the introduction of Amazon’s pioneering AWS. That’s why we, along with a team of industry experts, formed an AAMI Consensus Report Task Group to tackle this issue.
AAMI CR:510:2021, Appropriate use of public cloud computing for quality systems and medical devices, seeks to answer the question: How can we maintain a validated state for our software when it is on a third-party computing platform that we do not fully control? The Task Group considered all of the benefits of the cloud and all of the challenges it raises, and determined that, given the circumstances, a continuously validated state cannot be achieved. Rather, the best that could be achieved is an intermittently validated state.
An intermittently validated state is one where the validation is periodically examined and confirmed. It is a risk-based approach similar to the risk mitigation our industry undertakes when building a system of systems or relying on hardware provided by our clients. We need to get in the habit of asking ourselves: What changes can occur between validations? How likely is it that each change will impact safety and effectiveness? How do we detect the change? How long will it take for us to correct it, and what harm could happen in between? As long as medical device developers and manufacturers plan for the changes that may occur in real-time in the cloud, and respond thoughtfully and responsibly, the intermittently validated state can be reliably managed.
The cloud will continue to change and grow, and medical device developers should expect the unexpected to happen. Medical device developers can tame the uncertainty of the cloud by approaching it with a proactive mindset through the below six key recommendations.
The crux of the Consensus Report comes in the form of six key recommendations for responsibly embracing the cloud to support the operation of a medical device:
These recommendations do not exist in a vacuum. They build on, but do not replace, existing industry practices and standards such as ISO/IEC 62304, ISO 13485 and 14971. As we continue to support and develop industry standards, Orthogonal and partners at AAMI will align our cloud guidance so they are consistent with the existing practices and standards.
After the annual AAMI/FDA/BSI International Conference on Medical Device Standards on October 18th–19th, 2022, Orthogonal’s Randy Horton, Chief Solutions Officer, and Philip’s Pat Baird, Regulatory Head of Global Software Standards were invited to the AAMI Studio for a conversation with Robert Burroughs, Chief Learning and Development Officer, and Joseph Lewelling, Senior Advisor, Strategy and Content. You can watch the recording of their conversation in the following video:
An AAMI Consensus Report is an initial discussion and guidance in emerging areas – it sets the tone for a formal examination into the topic. AAMI has organized Software Working Group 10 to develop a Technical Information Report on the subject, a process that will take time but that will produce even more valuable guidance on cloud computing in the MedTech industry. Randy Horton from Orthogonal and Pat Baird from Philips will reprise their CR roles as co-chairs for this TIR, and Bernhard Kappe will continue to be involved. It’s critical that Orthogonal and our business partners continue to help define standards for our industry.
The Consensus Report Task Group will lead conversations about their findings across the community. In doing so, our industry can continue to responsibly adopt cloud computing, as well as contribute to shaping future guidance in a patient-centered, trust-focused way.
