PeDS SIG Immunization Registry Storyboard iteration #4 Precondition: Billy Newpatient is 4 years old. He has been seen at other clinics in the state. However, he is a new patient at Dr. Shotzs clinic. He is there for a pre-school physical. Dr. Shotz's clinic EMR is able to interface with state/local immunization registry. The state/local immunization registry conforms to CDC Minimal Functional Standards for Immunization Registries. The clinic EMR conforms to HL-7 EHR-S Functional Model. The state/local registry is able to locate the patients immunization record. Storyboard: Billy has previously been seen at other clinics in the same state. The caretaker does not have his immunization record. In preparing his new patient record for Dr. Shotz to review, the nurse initiates the clinic EMR to query the state immunization registry. The immunization registry finds and sends data to clinic EMR. The clinic EMR populates Billys patient record with that data. The clinic EMR generates immunization recommendations using a decision support engine. Alternate Flow #1: The state registry uses a decision support engine and sends recommendations along with Billys immunization data. Dr. Shotz reviews the record and notes (amongst other data) Billys immunization record (or its absence thereof) and recommendations. After taking history from the caretaker and performing physical exam, she orders immunizations. The nurse administers the shots and documents them in the clinics EMR. The clinic EMR sends the message about the new immunizations to the state registry which updates its record. The nurse also prints an updated paper record of Billys immunizations. Alternate Flow #2: Dr. Shots determines that Billy does not require or decides to withhold immunizations at this stage. No updates are made to the immunization history in the patient record. No data is sent to the registry. Post-condition: The state registry has successfully sent Billys immunization history. The state registry has successfully recorded Billys new immunizations. The clinic EMR has an updated immunization record. The patient has an updated immunization record.

Lessons learned Significant domain expert involvement Considerable iterations Constant communication during the build Balance between level of detail and granularity vs. degree of consensus vs. work effort Requires a standardized building approach

Next Steps Scope of future project (focus on Immunization) Breadth – requires more domain expertise Depth – requires more technical expertise (i.e., informatics, engineers, developers, etc.) Pediatric focus? PeDS SIG resources Clinicians Registry experts Public health Informaticians Vendors? International?
Examples of Breadth Information System and Registry communication Hospital Military Health systems (i.e., Indian Health Service) School health systems RHIO Surveillance system Registry to Registry communication (high level) HL7 Continuity of Care Document Harmonization of CCR and CDA Immunization section Others?
Examples of Depth EMR process EMR queries registry EMR receives info from registry EMR updates registry EMR updated by registry EMR IZ decision support processes EMR and Registry Process map for indications to withhold IZ (contraindications, previous disease, etc) Inventory information exchange between registry and EMR Reporting of adverse reactions Sending batched requests from registry Registry processes Registry receives query for a client from a registry or other IS Registry receives answer to query for client info Registry receives unsolicited update of a client record Registry receiving batched request for a number of patients
Next Steps Divide and conquer Breadth? Depth? Engage with HL7 IZ project Follow-up Patient Care TC Follow-up leading to message definitions Pursue evidence of tangible impact/contribution within HL7 development process Begin project documentation (storyboarding process) Publish Guidebook
