Quality Assurance in Healthcare: 6 Essential Considerations

Security and Compliance Testing

There’s a wide range of regulations and policies healthcare applications must comply with to guarantee personal and financial data protection. They include HIPAA, HL7, PCI SSC, and more. Healthcare apps are generally connected with storing and using large amounts of sensitive information – personal ID numbers, insurance, social security, etc. This means that even minor app vulnerabilities can result in massive data leaks, leading to losses of customers, money, and credibility. However, leaks can be avoided with the help of vulnerability assessment, security code review, user data encryption, and automated software testing.

UI/UX Testing

In the healthcare industry, many users are senior citizens who may have difficulties adjusting to new technologies. That’s why the design of healthcare apps should be intuitive and user-friendly. UI/UX testing will assist in determining the possible issues the users may encounter when using the app.

The testing involves two stages: static and dynamic healthcare application testing phases. As the name suggests, static testing implies reviewing the non-dynamic app design. During this phase, QA specialists check whether the app design fits user requirements and business logic. During the dynamic stage, the specialists can see how the app design deals with different requests and runs in dynamic conditions.

Integration Testing

Although the main actors in the healthcare industry are providers (hospitals, doctors, nurses, labs) and receivers (patients), there are also insurance companies, solution vendors, and regulatory authorities. These entities may operate on different software, but they should all be able to receive and store the needed data. This calls for multiple API integrations.

Compatibility and Interoperability Testing

Since patients and healthcare facilities may use various devices, operational systems, browsers, etc., it’s essential to check that the software operates properly and smoothly across the platforms. Many apps are connected with IoMT devices, so efficient data transfer must be secured. Compatibility testing helps avoid system errors, data inconsistencies, and connection problems. Healthcare apps and the linked devices should cooperate seamlessly and ensure accurate data exchange.

Performance Testing

Performance testing is essential to identify glitches that disrupt the app’s operation. It’s also an excellent way to test other productivity requirements, such as load, stress, endurance, and volume. For example, you can check how different variables, like device type, connection quality, location, or the number of concurrent users, affect the app’s speed. Creating a user load to see how the application will handle high simultaneous user activity will help determine its limits and possible ways to improve this.

Regression Testing

You must run regression after every round of iterations, be it updates, novel features, or fixes. This will ensure that the bug-fixing process doesn’t change the initial code or expose other issues.

Improving Code Quality for Healthcare Solutions

01
Test plan strategies

QA testing in the healthcare domain is more complex than the standard procedure because of the demanding requirements. Testing requirements should serve the needs and experiences of all users, including healthcare providers, patients, insurance companies, etc. QA specialists must ensure that these different test sets meet all critical requirements:
- Performance testing. Check the software’s performance, scalability, architecture, and tuning.
- Vulnerability assessment and penetration testing. Assess the app’s security level and resistance to hacking.
- UX testing. See if the UX design is intuitive and user-friendly.
- Localization testing. Verify that the software is capable enough to be used in a specific culture or region.
- Compliance testing. Check if the software complies with regulatory requirements and policies like HIPAA, HL7, etc.
Automated testing is a software technique that uses specialized tools to run a suite of test cases automatically. It is often used in test cases for the above-mentioned testing. This helps deliver faster and more accurate results than manual testing methods.
02
Setting security standards from the start

Setting the security standards from the start will prevent gaps, hacking, and security issues.
- Test your app in accordance with all necessary healthcare regulations to guarantee compliance.
- Perform end-to-end testing to keep sensitive information secure within the software.
- Devote time and resources to training all testers on healthcare standards.
03
Leverage a comprehensive testing framework

Establish strict guidelines and rules for test cases to avoid possible mistakes and mismanagement of time and resources. Automated testing allows the QA specialists to handle the data volume across various platforms, operating systems, and environments in a time-saving manner.
- Functional testing. Ensure that the software transmits the information securely and correctly in all situations.
- Data-driven testing. Check that the app handles patient data accurately and safely, even with high user volume.
- Authentication verification. Ensure the authentication process runs smoothly and the security features work properly in all user scenarios.
- Repetitive testing. Check that all the processes run smoothly within the software, regardless of the number of test cases executed.
- Multi-platform testing. Ensure the application performs seamlessly and bug-free across multiple devices, platforms, and browsers.
04
Documenting

Documenting every step of the healthcare software testing makes the process easier and more systematic. A unified reporting system keeps the data well-structured and in one place, saving time and money.
- Introduce the system at the start of your project.
- Determine the rules, who documents what, and at what stages.
- Develop standardized templates for each type of documentation to be consistent and unified.
- Make documentation an integral part of your QA engineers’ day-to-day operations.
05

Coordination with the development team

Proper testing can only be achieved through close cooperation between the QA specialists and the development team. Testing isn’t an isolated process; it can become much easier and more efficient if team communication is established. In this way, every specialist works as a part of the team to enhance teamwork, product quality, and delivery.
