The recent pandemic has an eye opener for many of the industries and service providers to become digitally able for their beneficiaries/customers. In this line, Digital Health Mobile applications have taken a great leap and made the healthcare, labs, and pharmacies available at home in our fingertips.
The rapid spread of Internet use, fast Internet connections, mobile devices, social networking, etc. has made it possible for creative concepts and inventions to be made for the benefit of digital health. There was a resoundingly positive response to the electronic health record exchange between healthcare professionals and beneficiaries, including patients and their careers. Additionally, individuals with chronic diseases, older people, and those who use such applications or devices would have more control over their own health. It is widely understood and acknowledged that mobile health can enhance the overall healthcare system by offering affordable, effective, and high-quality medical services to people.
The current and future of health care apps are created with the intention of integrating mobile apps and medical devices to monitor chronic conditions in order to achieve prescription adherence, vital monitoring, and precise health alerts, despite the fact that the majority of common health-related apps are primarily concerned with fitness, lifestyle and stress, and diet and nutrition. To make sure that developed apps work well with their service capabilities and are performing as expected, businesses are looking for Quality Assurance services.
Compliance Testing – In order to make a safe and effective medical device, it is every device maker/inventors’ responsibility to adhere to the various regulations and Act. It is added value for the quality team to be aware of those regulations and test the devices accordingly before delivering it in the marketplace.
Device Compatibility and Error Handling Testing – Before speaking of the compatibility of smart medical devices with the mobile apps, it is vital to test the behavior of the device under different error conditions and failures.
Security/Data Leak – It is a known fact that when we go for wireless devices, the data are prone to information hacking, transfer of personal/financial information to unreliable sources and may lead to security havoc.
Cochannel and adjacent channel interference – For e.g., In a physician’s waiting room, patients sitting side by side with two or more devices in or on then the Functioning of the device in the presence of other like devices without interference should be ensured.
Data Loss – There is a high chance of data lost due to Data synchronization issue, when the Bluetooth connection is lost, or device gets switched off or gets disconnected and connected to any other open wireless network.
Testing a medical device is critical as it has a direct impact on a patient’s healthcare. QA has a huge responsibility in ensuring the optimal working of medical devices and for that end-to-end medical device software testing is essential. Here are some testing techniques that can be used:
Authentication Testing – In order to prevent anonymous sensors, clone attacks and other security threats, it is essential for the tester to understand the Authentication system and try to break or bypass it, to report any loopholes at the earliest.
Co-Existence testing – Pass-fail criteria for co-existence testing must be identified and need to be quantified in terms of the critical functions of the device under test as determined by risk assessment.
Data Sync Testing – When wearable apps get synced to each other, the data on the actions performed by the user in Apple Watch or in other devices need to be synced properly without any technical issues.
To trouble shoot this, it is important to test whether passive tracking and active tracking features are implemented.
End-to-end devices testing – To ensure whether patient mobile apps, medical devices software, and Patient Database management systems work seamlessly under various scenarios.
Performance testing – To check the robustness of the connectivity and performance of the connected devices in various sets of situations.

App crash Testing – There may be many issues that cause App crash. But few of them can be troubleshooting at the testing phase.
Functional testing – To check whether all the functionalities and usability of the UI are on point and how the devices operate in all those modes while being part of the network.
Any technical glitches in medical device software may lead to false diagnosis, misleading EMR and may lead to fatal results to the patients and hence it is in QA’s hands to ensure the proper performance and functioning of the medical devices.
Emulators/Simulators are virtual replications of real smart phones. In the initial stage of development, it is a smart way to run the developed application across several devices and platforms to ensure the functionality/behavior of the application in wide variety of devices and operating systems. Buying 10 to 15 phones for each application that is developed is not a reliable option and hence simulators/emulators are highly recommendable during initial unit testing and for quick debugging. Also, when we consider factors such as Accuracy, User experience, Accessibility, Wireless connections of other smart devices, Memory/Cache/ Storage defects and Security, testing on physical device ensures the stability of the application.
Using Emulators/Simulators in the initial phase and testing on Real devices during system testing provides dual assurance on the application before it is delivered for UAT.
To ensure nothing is missing before the App launches in Appstore/Play store, the following launch checklist can be followed to ensure that nothing is missing at the last moment.
