1.3.3 Pediatric Immunization (DOPC_ST000030)Purpose: This storyboard demonstrates the interaction between a Primary Care Physician (GP) to an immunization registry for the region.

1.3.3.1 Pediatric Immunization (DOPC_SN000030)

Precondition: Billy Newpatient is 4 years old. He has been seen at other clinics in the region. However, he is a new patient at Dr. Primary's clinic. He is there for a pre-school physical. Dr. Primary's clinic EMR is able to interface with a regional immunization registry. The regional immunization registry conforms to public health standards, e.g. CDC Minimal Functional Standards for Immunization Registries. The clinic EMR conforms to HL-7 EHR-S Functional Model. The regional immunization registry is able to locate the patient's immunization record.

Activities: By interview, the nurse discovers Billy's caretaker does not have his immunization record. In preparing his new patient record for Dr. Primary to review, the nurse initiates the clinic EMR to query the regional immunization registry. The immunization registry finds and sends data to clinic EMR. The clinic EMR populates Billy's patient record with that data. The clinic EMR generates immunization recommendations using a decision support engine.

Alternate Flow #1: The regional registry uses a decision support engine and sends recommendations along with Billy's immunization data. Dr. Primary reviews the record and notes (amongst other data) Billy's 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 clinic's 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 Billy's immunizations.

Alternate Flow #2: Dr. Primary 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 regional registry has successfully sent Billy's immunization history. The regional registry has successfully recorded Billy's new immunizations. The clinic EMR has an updated immunization record. Billy's caretaker has an updated immunization record.

Immediate steps to developing HL7 conformant messages

Developing the interaction models Domain Message Information Model (D-MIM) Refined Message Information Model (R-MIM) Hierarchical Message Definitions (HMD)

Submit for HL7 Ballot process Approve the D-MIMs, R-MIMs and HMDs Any new messages that require additions/modifications to the

RIM, then these will need to be submitted to the RIM review process.

Messaging areas EMR requests immunization history from registry

Immunization Record Detail Query EMR receives immunization record from registry

Immunization Record Detail Query Response EMR receives immunization recommendations

from registry or other systems Immunization Recommendations Query Immunization Recommendations Query/Response

EMR updates the immunization record of a patient in the registry Immunization Event Record Request

Examples of other message areas 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 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
