Early diagnosis of infectious diseases and monitoring of community health are essential for delivering cost-effective healthcare solutions. Healthcare delivery in developing coun- tries have many challenges because they do not have enough resources for meeting the healthcare needs, and they lack testing lab infrastructures in communities. It is necessary that a solution must be developed to safeguard the impacted communities. It has been proven that Point-Of-Care (POC) testing can be considered as one of the ways to resolve the crisis in healthcare delivery in these communities. The term 'POC testing' has been used in many contexts. Use case, where a passenger in an autonomous vehicle is driven to the nearest hospital for an emergency treatment due to an alert received by the health monitoring system in the car. The POC that the research exploring is for the use for a remote patient who does not have access to lab testing facilities because of the social and economic conditions in that community. The POC testing is a mission critical processes in which the patient conduct tests in a home environment, as opposed to the tests undertaken otherwise in a laboratory facility and it needs a communication system of architecture support which the research refers as POCT system. The research looked at the requirements and made recommendations concerning critical aspects: requirements gathering for POCT system, design and development methods of secure communication architecture, finding a suitable strategy for testing the system and project managing the end-2-end process. Data security is another critical factor in healthcare data. The research came up with secure data communication architecture and processes for the system. A secure data storage for the test results are needed, and the research came up with an architecture for cloud storage. Deployment and expansion of the secure communication system are essential for practical use cases based on community needs, and a scalable communication architecture was developed to support the objective.

▪ Problem
▪ iCDG manages data for more than 20+ operators and performs
gap analysis. There are requirements which are co-related and
understanding connection of requirements with operators is
crucial. Development and testing teams perform redundant
tasks which slows down overall process of development
lifecycle.
▪ Current Approach
▪ All the data is maintained by JAMA and requirements are
updated manually. It increases time to deliver a product in
market.
▪ Business Value
▪ Understanding relationship between requirements and
operators is crucial from business perspective. This will help
effective time management, plan future platforms as per
operator requirements and it can increase productivity of
business unit. Saffron is good at natural language processing
and provides in-depth analysis of relationship in textual data.

PoC: Point Of Care Testing (diagnosis)
9
• A method for bringing medical laboratories to a patient’s home to
conduct diagnostic tests
• patient does not need to go to the doctor or laboratory in person.
• PoC testing reduces the burden on expensive laboratory setups and provides
management of patient care in cost effective manner.
• PoC device and the associated infrastructure must be done with extreme
rigor, as the PoC system meets the definition of a mission critical or safety
critical system.
• Requirements creation and management are the key processes for ensuring
that a highly reliable and low defect PoC system is developed since accurate
PoC testing-based diagnosis is an essential process improvement for
remote patient care management.
• Provides physicians a vehicle to diagnose patients with drastically
increased reliability
• Battery performance management is an important functionality:
• Need to have uninterrupted power during PoC testing.
