Whether it is a smartwatch that keeps track of your heart rate or an AI that analyzes a medical image, MedTech software was once a luxury, but now it is a must-have. It is an online skeleton of the contemporary healthcare, capable of bringing more personalized, convenient, and efficient care to the patients.
The need is ever-growing with graying populations and the increase in healthcare expenses, and it does not seem like it is going to decrease shortly, which is why this is such a boom time to be thinking about entering the MedTech arena.
Nevertheless, the development of MedTech software is a process unlike any other. It is not merely writing code; it is saving lives, and hence, you need MedTech Software Development services.
This handbook will take you through the details you need to know on how to develop a successful and compliant MedTech software solution, from the initial development phase to post-market surveillance.
The MedTech Software Landscape: What are the Types?
However, before the phase of development, it would be important to take cognisance of the various categories of MedTech software. The first and most basic of the distinctions is the one between Software in a Medical Device (SiMD) and Software as a Medical Device (SaMD).
| Feature | Software in a Medical Device (SiMD) | Software as a Medical Device (SaMD) |
| Definition | Software that belongs to a hardware medical device and without which the latter cannot operate. | A medical purpose standalone software not connected with a hardware medical device. |
| Functionality | Regulates and activates the piece of hardware. | Performs a medical role in itself, including diagnosis, surveillance, or treatment. |
| Regulatory Path | The software is controlled with the rest of the hardware device. | The software has been regulated as a medical device and requires clearance or approval from the relevant regulatory body. |
Key Types of MedTech Software
MedTech Software Development services incorporate various types of MedTech Software, and each of them plays a specific role in the healthcare system.
- Electronic Health Records (EHR)/Electronic Medical Records (EMR): The electronic backbone of healthcare, such systems can manage patient records, medical history, and clinical notes.
- Telemedicine and Telehealth Locations: The platforms are capable of offering distance consultation, virtual treatment, Remote Patient Monitoring (RPM), and encouraging more feasible access to treatment, especially to patients in rural settings.
- Medical Imaging and Diagnostics Software: Included in this category of diagnostics are PACS (Picture Archiving and Communication Systems)/DICOM viewers, and high-tech AI-based medical diagnostic software systems that support radiology and clinicians during the interpretation of medical images.
- Hospital and Practice Management Systems: They too are solutions that automate their administrative aspect, scheduling, and billing of the patients, inventory requirements, etc.
- mHealth (Mobile Health) Apps: Consumer-centric apps, and may also be wellness, fitness, chronic disease management, e.g., a heart rate monitor or diabetes management app.
- Clinical Decision Support Systems (CDSS): These are the systems that interpret patient and other data and information to assist healthcare organizations in making evidence-based decisions.
The Absolute Must-Know: Regulations and Compliance
Compliance is not only an obstacle, but it is a baseline. Lack of compliance may result in huge fines, product recalls, and, most significantly, vaccine injuries.
- HIPAA (Health Insurance Portability and Accountability Act): This is an act made in the U.S. that establishes standards to protect the sensitive data of a patient. It requires physical, network, and process safeguards.
- FDA ( Food and Drug Administration): In the U.S., the governmental supervising body over medical devices is referred to as the FDA, which categorizes medical devices into three classes of risk: Class I, Class II, and Class III. There are varying pathways to market, a 510(k) & a PMA (Premarket Approval), each, respectively, of Class II and Class III.
- GDPR (General Data Protection Regulation): GDPR is the EU equivalent of HIPAA, even when it provides EU citizens better control over their data.
- MDR (Medical Device Regulation): A new, more restrictive regulation in the EU under which manufacturers have a greater burden to show that their devices are safe and perform, rather than show that there is no evidence of the opposite.
- ISO 13485 & IEC 62304: These are the required global standards. The requirements of QMS of medical devices are specified in ISO 13485, whereas IEC 62304 defines medical device software lifecycle requirements.
Modern MedTech Software Tech Stack
The health technology (MedTech) sector is experiencing a revival in terms of the widespread adoption of advanced medical software technology stack, which effectively incorporates state-of-the-art tools and frameworks.
With this stack, developers now have the power to develop secure, scalable, and compliant solutions that provide better performance of patient care, clinical workflow, and innovation.
- Programming Language: Python and C++ are the most favorable programming languages used in AI and machine learning and embedded systems, respectively.
- Backend Platforms & Clouds: The market leader, AWS, along with Azure and Google Cloud, have dedicated healthcare compliance programs with HIPAA-eligible services, so this is a natural fit.
- APIs & Interoperability: The industry standard in APIs and interoperability is FHIR (Fast Healthcare Interoperability Resources) and is built upon REST. Developing your software using FHIR APIs will enable the successful incorporation of interconnections into other systems.
Medtech Software Development Lifecycle- A Step-Wise Guide
MedTech software development lifecycle is an elaborate, staged, gated process where safety, efficacy, and compliance are the top priorities.
Conceptualization and Market Research
It is through this that you get started. To begin with, discover a market need that is not being fulfilled. Does patient care suffer a blind spot? Does an existing process consume a lot of time? Then, know your target market-will your solution be for patients, providers, or administrators?
Find your unique competitive advantage by conducting a competitive analysis to understand what other players are doing. Above all, identify the class of the device (e.g., FDA Class I, II, or III) since this will be the determinant of your whole regulation and development.
Requirements Gathering / Risk Analysis
The step is entirely about settling what you want done with your software, more importantly, what could fail. You will have to develop an elaborate user needs and requirements analysis. This is where the Design Control process and Quality Management System (QMS) will play a very important role.
You should start writing down everything from the first day. You will also have to conduct a full risk analysis following standards such as ISO 14971 to determine the potential risks that might occur due to software malfunction and develop mitigating measures.
Design & Architecture
In this situation, you will embody requirements in a concrete design. Emphasizing UI/UX design spectrum with much focus on human factors and using usability engineering (IEC 62366-1) to make the software intuitive and safe to operate.
You will even design your system architecture, choose between on-premise, cloud-based (e.g., AWS, Azure), or hybrid solutions. Make sure you do not neglect standards such as HL7, FHIR, and DICOM when it comes to having your software integrate with other healthcare systems (and so easily exchange information there).
Implementation and Development
Now that you have a design, it is time to develop software. Select an appropriate technology stack. Although it is possible to apply agile methodologies, all steps must be carefully documented and can be traced to the requirements. This is essential traceability for regulatory audit.
Verification, Validation, and Testing
This step is your software verification to ensure it operates as it should and without problems. Verification replies, did we build it right? via such practices as code reviews and unit tests. Validation, “Have we made the right product?” involves acceptance and usability testing by users.
You have testing to get done in different forms, such as security testing, performance testing, or regression testing, and all of this should be achieved by following standards such as IEC 62304 of the medical device software lifecycle processes.
Post-Market Surveillance and Regulatory Submission
When your software has been tested and passed, you get the regulatory clearance. This will include planning to go through FDA clearance/approval in the U.S or acquiring CE Mark in the EU. The perfect center of this submission will be based on your QMS documentation.
And the trip does not stop there. Post-market surveillance is an ongoing effort to ensure the monitoring of the software in the real world, complaints management, and update management in a strictly regulated environment.
Key Challenges and How to Overcome Them
Since health care is sensitive, highly regulated, and data must integrate well with the existing environment, the creation of the HealthTech software, applications, platforms, and systems that aim at ensuring improved healthcare delivery, patient outcome, or operational efficiency poses some special challenges.
The following is an investigation into the major challenges discussed, including navigating an extensive regulatory environment, ensuring data security and privacy, achieving interoperability, and balancing innovation and safety, and the solutions to each, respectively.
Surviving in a Dotted Regulatory Landscape
Challenge: Regulatory adherence (HIPAA, GDPR, FDA, etc.) is region-specific and intricate- failure to comply with regulations can cost millions of dollars in fines (e.g., HIPAA violation fines cost $1.5M).
Solution:
- Co-ownership with intensity regulators to decode requirements.
- Introduce Quality Management System (e.g., ISO 13485) at an early stage.
- Engage there as part of the development process.
Securing Data and Privacy
Challenge: Safeguarding confidential health information and data (average cost per breach: $10.1M) to prevent information leakage, loss of trust, and even penalty is a must.
Solution:
- Data protection should be done via AES-256 encryption and connection via TLS 1.3.
- Implement role-based access control and two-factor authentication.
- Do frequent security audits (e.g., SOC 2, ISO 27001).
Achieving Interoperability
Challenge: The current situation where incompatible systems exist, and only 59 percent of U.S. hospitals manage to share their data externally (ONC, 2021).
Solution:
- Design APIs to integrate with (e.g., RESTful API).
- Comply with such standards as FHIR to exchange data in a standardized form.
- Test the interoperability of the test with actual systems.
Innovation vs. Safety
Challenge: Systems such as AI have to be safe; failures (e.g., wrong diagnosis) can be fatal, and laws do not keep up with the pace of technical progress.
Solution:
- Use a risk-based approach (e.g., ISO 14971) to prioritize safety.
- Carry out a full testing process, even AI validation using different datasets.
- Collect regular feedback from users to maintain usability and reliability.
Trends in MedTech: The Future has already come
MedTech will be dynamic, and it will be enforced by emerging technologies in the future.
- Artificial Intelligence and Machine Learning: AI is employed in anticipative diagnostics, individualized treatment regimens, and image analysis. This becomes an issue of the black box problem, i.e., how the AI came to a conclusion, which may provide a regulatory obstacle.
- Internet of Medical Things (IoMT): The value of Remote Patient Monitoring (RPM) is being made possible by a vast array of connected appliances, including wearables and smart hospital equipment. This poses issues of data security and device interoperability.
- Cybersecurity is a Priority: As the number of devices scales up, cyber threats are increasingly becoming rampant. The alternative, a so-called secure by design approach, which entails security being incorporated at the foundational level, is no longer optional.
