Introduction

The Generic Electronic Immunization Information System, GIIS, helps countries improve the administration of their vaccination programs, improve immunization coverage and produce more accurate, timely and relevant performance. In addition, this system currently helps in the management of patient data, vaccinations, adverse effects (ESAVI), inventory management (stock) and cold chain.

Explanation of the problematic

The GIIS system currently has an API that allows some non-standardized and sufficient operations, which makes interaction with other systems difficult. Therefore, the main requirement of this project is to add to the GIIS system a data exchange mechanism in a standardized and secure manner (an interoperability layer based on HL7 FHIR) that allows it to interoperate with external systems patient data, vaccinations, adverse effects, inventory and cold chain. Inventory and cold chain are not part of this solution, however is seems worth mentioning them.

Proposed Solution

The proposed solution is a facade to work as standardize interface. With that, external entities who wants to interoperate with GIIS systems can execute only allowed operations, going throw an authentication and authorization server, and those operations should be FHIR R6 compliant.

The onboarding process is described as follows:

Discovery and Planning (Phase 1)	Development and Testing (Phase 2)	Production Approval and Go-Live (Phase 3)
1. Provider completes onboarding registration form 2. Provider completes onboarding questionnaire 3. Provider reviews GIIS FHIR documentation 4. Review of onboarding registration form 5. Review of onboarding questionnaire 6. Discovery onboarding kickoff call 7. Define project scope	1. Generate and share GIIS test environment credentials 2. Establish connectivity with test systems 3. Perform test of the various API endpoints 4. Conduct review call to discuss findings (data quality, and validation) 5. Confirm and share approval to proceed with go-live	1. Generate and share GIIS production environment credentials 2. Establish connectivity with production systems 3. Commence monitoring post-go live 4. Conduct review call to discuss findings and to close out the onboarding project 5. Ongoing – continue to monitor the provider organization interface
