BACKGROUND:
With the delivery of immunization services to patients spanning state lines and movement of families between states, immunization programs recognize the need for state to state registry capabilities to search for and combine vaccination records that exist within registries outside of their jurisdiction.
In line with PHIN standards, the Health Level Seven (HL7) Standard Protocol has been accepted as the method of choice for communication compatibility between immunization registries and external systems including billing systems and electronic medical records. In many states, Statewide Immunization Information Systems (SIIS's) have implemented this functionality, while other states are working toward this needed capability.
OBJECTIVE:
This presentation will discuss the benefits of SIIS to SIIS data exchanges, PHIN standards and the technology required to achieve this, confidentiality and security issues, and data sharing agreements between states. Secondly, the discussion will include a follow up on the current efforts among several states to exchange data, a description of these successes and challenges encountered.
METHOD:
Follow up review of four-state pilot project initiated in July, 2004. Technical, programmatic and legislative issues/solutions have been documented during the pilot for the presentation.
RESULT:
The pilot has resulted in successful data exchange between at least two states. The final result of the pilot among all four states will be determined prior to the March conference. It is expected that the technical barriers will be minor and the major efforts will focus on policy issues.
CONCLUSION:
Using PHIN standards, SIIS to SIIS data sharing capabilities improve data quality, decrease over-vaccination and decrease efforts to track/enter historical vaccinations. While significant efforts remain for states to establish formal data sharing agreements, technical solutions can sometimes help overcome policy issues.
LEARNING OBJECTIVES:
1. Describe benefits of state-to-state data exchange
2. Name 3 barriers encountered in the pilot.
3. Describe 3 solutions to the barriers.
