Healthcare Application Testing
Before we begin testing,
let's quickly understand the healthcare industry.
The entire health care
system is weaved with each other by the single body that is hospital or
provider (doctor).
While the other entities include-
·
Insurance company: Medicare, Medicaid, BCBS, etc.
·
Patient/Consumers: Patient Enrolled
·
Regulatory
Authority: HIPAA, OASIS assessment,
HCFA 1500 and UB92, etc.
Healthcare Business Process
Most health-care
organization have adapted software program to process the smooth functioning of
the system. This software system gives all the information in a single document
for each entity dealing with this.
Interconnecting this
whole system to a single web application is a huge task and making it work
effectively is even a bigger task. Rigorous testing of this health application
is compulsory, and it has to go through various testing phases.
Basic Terminology of Health
Care System
·
Provider: A health care professional (doctor), medical group, clinic,
lab, hospital, etc. licensed by health care services
·
Claim: A request to your health insurance company to pay a bill for
health care service

Performance testing of
Healthcare Application
Before preparing test
scenarios certain requirement of the system should be considered. For example,
health-care providers (Doctors/Hospitals) provide care 24/7, so the patient
check-in software needs to be available at all times. Also, it needs to
communicate with insurance companies to validate policy information, send
claims and receive remittances. Here, the architecture should define the
different components of the system, the protocol to communicate with insurance
companies, and how to deploy the system so that it complies 24/7.
As a tester, you need to
ensure that the healthcare software system meets the desired load/performance
benchmark.
Other Testing Types for
Healthcare Application
·
Functional Testing: Testing healthcare application against functional capabilities
·
Conformance Testing: Conformance test Healthcare security requisites and industry
frameworks
·
Platform Testing: Testing of applications on mobile platform and applications
testing for cross-browser compatibility
·
Interoperability Testing: Testing conformance to interoperability standards ( Eg; DICOM,
HL7, CCD/CDA)
Testing Challenges in
Healthcare Application
Testing challenges in
testing healthcare application are no different than other web application
testing.
·
Requires expertise in
testing, and usually it is high in cost
·
Requires
interoperability, compliance, regulatory, security, safety testing besides
regular testing techniques (Non-Functional, Functional and Integration testing)
·
Testing should be done
keeping in mind the safety and regulatory standards- as any error can cause
direct effect on patient's life
·
Testing team needs to be
well aware of the various functionalities, clinical usage, and the environment
the software will be used for
·
Health-care product
should comply with various standards like FDA, ISO and CMMI before it can be
used
·
Cross dependency of
software- testers need to ensure that any changes in one component or layer
should not lead to side effect on the other.
Healthcare device Testing
While health-care device
software is not the direct concern of patient, they also require a rigorous
testing like other software testing. For example, X-ray machines that are
controlled by software programs should be tested well because any testing error
in software can lead to a serious effect on the patient.
FDA (Food and Drug
Administration) has guidelines for mobile and web applications for medical
devices. While testing medical devices the proper functional test plan along
with pass and fail criteria is also the part of FDA guidelines. When test plan
is executed, the results are collected and reported to FDA. This process
ensures that the device meets the standard of the regulatory bodies.
Useful tips for Healthcare
Testing
While testing software,
you can consider some important tips for the testing healthcare system.
·
Dates are important and
needs to be accurate
·
While designing test
cases consider various parameters like different types of plan, brokers,
members, commission, etc.
·
Complete knowledge of the
domain is required.
