Health Level Seven: Why The number of interfaces between N systems is given by the formula I = (N 2 -N)/2. Linking systems only needs 1 interface, ; Linking 6 systems needs as many as 15 interfaces, (6 2 – 6) / 2 = 15 The benefits of using the HL7 standard increase rapidly with the number of systems involved. I = N 3 ( ) / 2 = 3 2 ( ) / 2 = 1 4 ( ) / 2 = 6

HL7 Message Elements An HL7 message specification is an ordered collection of one or more segment groups where each segment group is an ordered collection of one or more segments. A segment may be part of more than one segment group; it can also appear more than once within the same segment group. A segment is an ordered collection of fields. Each segment field is an instance of a data element. A data element may appear as a field in more than one segment or as more than one field within the same segment. Each data element is assigned a data type. A datatype may be simple or composite. A composite datatype is an ordered collection of one or more data type components; a simple datatype has no components. A data type component is an instance of a data element. A data element may appear as a component of more than one composite data type or as more than one component of the same composite data type. Segment fields and datatype components may be associated with a code table. A code table is a collection of code table items. Each code table item is a code system term from some code system. A code system may be HL7 defined, user defined, or defined by a third party. A code system term may be used as a code table item in more than one code table but may appear only once within the same code table.

39 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Usage (continued) R - Required A conforming sending application populate all R elements with a non-empty value A conforming receiving application process (save/print/archive/etc.) or ignore the information conveyed by required elements must not raise an error due to the presence of a required element, but may raise an error due to the absence of a required element For complete compatibility with HL7, any element designated as required in a standard HL7 message definition shall also be required in all HL7 Message Profiles of that standard message

40 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Usage (continued) RE - Required but may be empty May be missing from the message, but must be sent by the sending application if there is relevant data A conforming sending application must be capable of providing all RE element if it knows the required values for the element, then it must send that element if the conforming sending application does not know the required values, then element will be omitted A conforming receiving applications will be expected to process (save/print/archive/etc.) or ignore data contained in the element must be able to successfully process the message if the element is omitted (I.e. no error message should be generated because the element is missing

41 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office.

42 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Usage (continued) C - Conditional Predicate associated with this element that identifies the conditions under which the element must be present must be testable and based on other values within the message may be expressed as a mathematical expression or in text and may utilize operators such as equivalence, logical AND, logical OR and NOT The conforming sending and receiving applications shall both evaluate the predicate If the predicate is satisfied: See rules for R (Required) If the predicate is NOT satisfied: A conformant sending application must NOT send the element A conformant receiving application must NOT raise an error if the condition predicate is false and the element is not present, though it MAY raise an error if the element IS present

43 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Usage (continued) CE - Conditional but may be empty This usage also has an associated condition predicate similar to Conditional (C) If the predicate is satisfied: See rules for RE (Required but may be empty) If the predicate is not satisfied: The conformant sending application must NOT send the element The conformant receiving application MAY raise an application error if the element IS present X - Not supported Conformant sending applications will NOT send the element Conformant receiving applications MAY ignore the element if it IS present, or may raise an application error

Message Profile Identifier Uniquely identifies static and dynamic profile The static profile identifier is a means to uniquely identify a message profile, expressed as an ASN.1 Object Identifier (OID) The sending application uses the profile identifiers to determine the specific HL7 Message Profile to send Branch from ISO to HL7 and Message Profile

59 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. MSH-21 Message Profile Identifier Sites may use this field to assert adherence to, or reference, a message profile. Message profiles contain detailed explanations of grammar, syntax, and usage for a particular message or set of messages. Repetition of this field allows more flexibility in creating and naming message profiles. Using repetition, this field can identify a set of message profiles that the message conforms to. the first repetition could reference a vendor's message profile The second could reference another compatible provider's profile or a later version of the first vendor profile. As of v2.5, the HL7 message profile identifiers might be used for conformance claims. Prior to v2.5, the field was called Conformance Statement ID. For backward compatibility, the Conformance Statement ID can be used here.

117 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. The California State Immunization Information System (SIIS) is a collaboration of regional immunization registries, local health departments, the California Department of Health Services Immunization Branch, and a spectrum of key stakeholders across the state of California. The goal of SIIS is to ensure that health care providers have rapid access to complete and up-to-date immunization records. The objective is to eliminate both missed opportunities to immunize and unnecessary duplicate immunizations. SIIS consists of nine regional registries and two county registries. SIIS is a system of systems each independently managed and operated.

The scope of the California Statewide Immunization Information System (SIIS) Systems Interface Project (SIP) is to design, construct, and implement a centralized electronic messaging hub that facilitates the automated exchange of immunization related data within the state of California. The objective is to enable registry users to gain access to an individuals complete immunization history regardless of where that history is maintained. Project Scope

120 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. The premise behind the project is that, for many reasons, a persons immunization history data becomes fragmented over time. The data are stored and maintained in separate state registries and immunization provider information systems. Typical scenarios that lead to this situation are changes in a persons primary residence, changes in a persons primary healthcare provider, and ad hoc administration of immunizations such as during vacation or emergencies. Once a persons immunization data becomes fragmented across multiple registry or provider information systems it can be difficult to ascertain their current immunization status. This can result in over immunization or under immunization. Problem Statement

121 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. A combination of manual and automated processes are employed to address this issue. First and foremost, providers are encouraged to enroll in regional registries and to record administered immunizations in the registry. All providers within the jurisdiction of the regional registry will then have access to the same data. Second, a CIR (yellow card) with the persons immunization history is updated by administering providers and carried by the patient, parent, or guardian to all settings requiring an official immunization record. Finally, immunization data may be requested from a former provider by phone, , or fax and then entered into the immunization registry system. Current Processes

122 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. There are serious inefficiencies and limitations associated with the current processes used to address the fragmentation of a persons immunization history data. The yellow card is often out of date, misplaced or otherwise unavailable. Some healthcare providers operate in multiple regional registry jurisdictions and find the prospect of coordinating reporting to multiple registries to be too much of an administrative burden. Some providers would prefer to have an automated means of exchanging data between the regional registry system and their electronic systems. These providers object to entering data into regional registries because it involves redundant data entry. Current Limitations

123 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Today immunization information is not easily able to follow the approximately 30,000 CA children moving throughout the state each year. SIP will address this shortcoming by enabling the electronic exchange of immunization related data. The SIIS SIP Immunization Information Exchange System will support the electronic request and response for immunization data from one registry to another. Regional and county registries, healthcare providers, and multi-jurisdictional provider organizations will be able to participate in a SIIS SIP information network and use electronic messages based upon HL7 messaging standards to exchange immunization data.

Immunization Messaging Implementation Guide The Centers for Disease Control and Prevention (CDC) National Immunization Program (NIP) publishes an implementation guide for immunization data messaging. The title of the guide is Implementation Guide for Immunization Data Transactions using version of the Health Level Seven (HL7) Standard Protocol. The intent of the guide is to help familiarize developers of immunization information systems with HL7 immunization message definitions and encoding rules and provide a nationally consistent implementation of those messages. Changes to the guide are coordinated through the Data Exchange Steering Committee of the American Immunization Registry Association (AIRA) and its associated work groups. The members of AIRA are committed to advancing the exchange of immunization data using a common protocol.

127 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Immunization Messaging Implementation Guide The guide identifies the set of HL7 messages needed to enable information systems that maintain immunization records to transmit patient-specific immunization histories electronically to other systems to allow healthcare providers to have access to these records at the time health care is given. The use cases detailed in the guide indicate that data transmission will occur as the result of four activities: 1. a query from one system for a patients vaccination record that is held in another system using the HL7 VXQ message; 2. a response to a query containing multiple patient matches to the query, but not returning vaccination records using the HL7 VXX message; 3. a response to a query containing the vaccination record using the HL7 VXR message; and 4. an unsolicited update to a vaccination record using the HL7 VXU message. In addition to the messages used for the four primary activities the guide also includes specifications for transmission confirmation and exception notification messages; ACK and QCK.

SIIS SIP Message Level Profiles HL7 defines a message profile as an unambiguous specification of one or more standard HL7 messages that have been analyzed for a particular use case. It prescribes a set of precise constraints upon one or more standard HL7 messages. A message profile eliminates ambiguity in a HL7 message specification by declaring static and semantic constraints for constituent elements of a message and the expected dynamic behavior of conformant application systems. The SIIS SIP HL7 message profile is an extension to the NIP Implementation Guide. The profile is based upon version 2.1 of the guide published in September The profile extends the specifications included in the guide. The profiles do not conflict with the guide; however, they are more constrained than the guide. Messages that conform to the profile are conformant with the guide as well; although the converse may not be true. A message profile has dynamic definition and a static definition.

135 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. HL7 Message Profile Dynamic Definition The dynamic definition describes the supported use cases, interactions, and acknowledgement requirements. Use Case Model The use case portion of the message profile dynamic definition documents the scope and requirements for an HL7 message profile or set of message profiles. The use case model documents the purpose for each message exchange; defines the actors, including the sending and receiving applications; and document the situations in which the exchange of a particular HL7 message profile is required Interaction Model The Interaction Model illustrates the sequence of trigger events and resulting message flows between 2 or more systems. It may be in literal or graphical form. Graphical form should be a UML activity diagram. Acknowledgement Requirements The specific HL7 acknowledgments required and/or allowed for use with the specified static definition of the HL7 message profile is defined. Specifically, the dynamic definition identifies whether accept and application level acknowledgments are allowed or required. For any one static definition there may be one or more dynamic definitions. The dynamic definition defines the conditions under which accept and application level acknowledgments are expected. Allowed conditions include: Always, Never, Only on success, and Only on error.

136 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. HL7 Message Profile Static Definition The static definition describes usage rules, cardinalities, and code systems. Usage Rules Usage refers to the circumstances under which an element appears in a message instance. Some elements must always be present, others may never be present, and others may only be present in certain circumstances. HL7 has defined a set of codes to clearly identify the rules governing the presence of a particular element. These usage codes expand/clarify the optionality codes defined in the HL7 standard. Cardinality Cardinality identifies the minimum and maximum number of repetitions for a particular element (Segment Group, Segment or Field). Cardinalities are expressed as a minimum-maximum pair of non-negative integers. A conformant application must always send at least the minimum number of repetitions, and may never send more than the maximum number of repetitions. Vocabulary Specification Vocabulary specifications declare an organized set of code systems and code system terms. Code system terms are coded concepts including concept codes, concept names, and concept relationships. Code system terms are collected into value sets declared as code tables associated with segment fields and data type components. The static definition declares the value sets for tables associated with coded message elements. Some of the value sets are HL7 defined, third party defined, or user defined.

These tests should not result in anything being written to the error log. VXQ, QCK This scenario is a query for a patient that is known to have no match in the remote system. The remote system is expected to respond with a QCK. The test data should include patients with varying ranges of matching confidence. VXQ, VXR This scenario is a query for a patient that is known to match a single patient in the remote system. The remote system is expected to respond with a VXR. The test data should include patients with varying ranges of matching confidence. A subset of patients should have locked records to test the locked record alerting process

150 © 2010 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Test Scenarios Valid Message Syntax, Invalid Content This set of tests is intended to ensure that message construction and validation rules are properly implemented. These test are focused on content issues not syntax errors. The message profile and vocabulary specification are the source of validation rules. Missing required message element This scenario involves the omission of required message elements (segments, fields, or components). The omitted items in this test scenario are those that are specified as optional in the standard but declared as required in the SIIS SIP Message Profile. Such an error should result in an ACK message being returned to the message originator and an entry in the error log. Missing conditionally required message element This scenario involves the omission of conditionally required message elements (segments, fields, or components). The omitted items in this test scenario are those that are specified as optional in the standard but declared as conditionally required in the SIIS SIP Message Profile. Such an error should result in an ACK message being returned to the message originator and an entry in the error log. The test data for this scenario must include a mixture of data values that meet the predicate conditions and others that do not meet the predicate conditions relevant for the conditional elements.
