State of Oklahoma Interoperability and Integration Project


Project Summary

This grant allowed Oklahoma to explore and create plans for improved interoperability and integration in eligibility and enrollment, case management, and related functions across human services information technology systems, and explore integration with other programs in Oklahoma. Using partnerships of the Oklahoma Department of Human Services (OKDHS), Oklahoma State Department of Health (OSDH), and the Oklahoma Health Care Authority (OHCA), the Oklahoma Interoperability Grant project culminated in a roadmap for improved quality and efficiency of operations. The collection of roadmaps and white papers will enable agencies to prioritize the plans and identify projects that support implementation of federal priorities around health care implementation and streamline out-dated technology processes, reduce duplication of data and data entry, simplify the process for applying and retaining services for Oklahoma citizens, reduce errors,  improve communication to the customers, and create a seamless experience when inquiring about benefits, eligibility, and more.

Needs Addressed

Through participation in this grant, Oklahoma demonstrated how enhanced interoperability and integrations can improve service delivery, increase program efficiency, and/or reduce errors and enhance program integrity. The Oklahoma roadmap details what could/should be considered by other states.


This grant will allow OKDHS to further plan and explore the National Human Services Interoperability Architecture (NHSIA) and how it fits with the Medicaid IT Architecture (MITA) to develop an overall enterprise architecture for the health and human services agencies for Oklahoma. OHCA intends to standardize application components (services) that can be shared over an Enterprise Service Bus (ESB) and achieve interoperability using a federated hub and rules engine (integration engine). As planning and implementation for data sharing is standardized and streamlined, Oklahoma will implement the use of National Information Exchange Model (NIEM) allowing for a consistent and repeatable exchange of data that can be shared among states.


Deliverables (click on each deliverable below for more information)

  • Service-Oriented Architecture (SOA) Roadmap White Paper (FINAL)
    The purpose of the SOA is to provide OKDHS and its collaborating agencies with guidance regarding typical activities and initiatives that need to be executed as part of the SOA journey.
  • Data Roadmap White Paper (FINAL)
    The Data Roadmap was developed to be fully integrated, reusable, reduplicated (whenever possible) data exchange for reports and all services exchanged between OKDHS and other agencies and initiatives.
  • Business Processes Roadmap White Paper (FINAL)
    The Business Processes Roadmap is a collaborative effort to improve the business processes both interdepartmentally and externally in terms of quality and integrity of shared data exchanges.
  • Web Services Roadmap White Paper (FINAL)
    This deliverable includes the integration of the roadmap for the Service-Oriented Architecture (SOA) and the Enterprise Service Bus (ESB) to allow fully-automated data exchanges and service reusability for all services exchanged between OKDHS and OHCA and other initiatives.
  • National Information Exchange Model (NEIM) Analysis White Paper (FINAL)
    This document is an analysis of the NIEM framework and identifies the steps that need to be performed in order to implement a NIEM compliant exchange. The analysis selects a few scenarios within the Oklahoma environment to show how it can be customized.
  • Electronic Master Person Index (eMPI) Analysis White Paper
  • Electronic Master Person Index (eMPI) Analysis White Paper - Appendix A
    This document is a roadmap for a statewide Enterprise/Electronic Master Patient/Person Index to consolidate client records across agencies to create a unique and non- duplicative client record.
  • Final Report
    This Final Report summaries Oklahoma’s efforts to explore and plan for improved interoperability and integration in eligibility and enrollment, case management, and related functions across human services information technology systems, and integration with other programs.
