March 2005V2 Messaging Conformance19 of 122 Compliance and Conformance Compliance Messages that adhere to the rules and conventions for constructing of a specific version of a standard are compliant to that version of the standard. Conformance Messages that adhere to the constraints of a precise and unambiguous specification called a message profile are said to be conformant to the profile. ComplianceConformance

March 2005V2 Messaging Conformance20 of 122 Conformance Project Background Began in 1997 by the HL7 Conformance SIG The SIG, in conjunction with the Andover Working Group (AWG), prepared this specification to: Define the HL7 Message Profile Recommend a specification for defining specific message profiles of HL7 messages Facilitate HL7 interpretation by users familiar with the HL7 standard, reducing interface analysis time and dissatisfaction with the HL7 standard

March 2005V2 Messaging Conformance22 of 122 Message Profiles What and How

March 2005V2 Messaging Conformance23 of 122 Message Profile Defined Unambiguous specification of a standard HL7 message for use within a particular set of requirements Prescribes a set of precise constraints upon one or more standard messages Supported by use case analysis and interaction modeling Measurable What data will be passed in a message The format in which the data will be passed The acknowledgement responsibilities of the sender and receiver

March 2005V2 Messaging Conformance24 of 122 Message Profile Defined (continued) Based on HL7, although may further constrain Static structure and content of each message The dynamic interactions Parts of a valid message profile Use Case Model Static Definition Dynamic Definition Represented as an XML document Can be registered with HL7 May be reused by other HL7 users May be used for documentation

March 2005V2 Messaging Conformance25 of 122 Conceptual Overview Message Profile = Static Profile + Dynamic Profile Critical Care Unit ADT System Initiating Message Response Message Initiating Message Clinical Data Repository

March 2005V2 Messaging Conformance26 of 122 Use Case Model Documents the scope and requirements for an HL7 Message Profile or set of Message Profiles May include a use case diagram or detailed text Provides a name that clearly and concisely defines the exchange Defines the actors, including the sending and receiving applications Defines the responsibilities of these actors Documents the situations in which the exchange of a particular HL7 Message Profile is required Documents the purpose V3.0 Message Development Framework (MDF 99)

March 2005V2 Messaging Conformance27 of 122 Static Definition A specification for a message structure intended to support the use case Based on a message defined in HL7 Std Defined at the message, segment, and field levels Follows the HL7 rules (chapter 2) May further constrain Identifies only those specific elements used in the exchange Removes all instances of optionality, defining explicitly Segments, segment groups, fields and components usage rules Cardinalities Value sets and coding systems Implementation notes

March 2005V2 Messaging Conformance31 of 122 How it all ties together

March 2005V2 Messaging Conformance32 of 122 Message Profiles Concepts and Constituents

March 2005V2 Messaging Conformance33 of 122 Profiling Concepts Profile Types HL7 Standard Constrainable Implementable Future type to allow for expected receiver behavior Generic term element used Segment groups Segments Fields Components Sub-components Cardinality Usage Message Constituents

March 2005V2 Messaging Conformance34 of 122 Profile Types HL7 Standard Profile represents a specific HL7 published standard creation and publication limited to HL7 use Constrainable May have optionality - not implementable Narrower profiles may be defined based on this Realm Specific (National, Regional, SIGs, etc.) Supplier / Consumer Specific Implementation Further constrained No optionality

March 2005V2 Messaging Conformance35 of 122 Cardinality Identifies minimum and maximum number of repetitions Special values for cardinality Minimum number of repetitions is 0, the element may be omitted from a message The maximum value may have no practical limit (In this case, it may be identified as *)

March 2005V2 Messaging Conformance36 of 122 Cardinality Examples Examples of common cardinality combinations are: Element Cardinality

March 2005V2 Messaging Conformance37 of 122 Usage The circumstances under which an element appears in a message Some elements must always be present others may never be present others may only be present in certain circumstances Rules governing the expected behavior of the sending and limited restrictions on the receiving application with respect to the element

March 2005V2 Messaging Conformance38 of 122 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

March 2005V2 Messaging Conformance39 of 122 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

March 2005V2 Messaging Conformance40 of 122 Usage (continued) Optional This code indicates that the Usage for this element has not yet been defined May NOT be used in Implemention profiles (no-optionality profiles) Conformance cannot be tested on an Optional field

March 2005V2 Messaging Conformance41 of 122 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

March 2005V2 Messaging Conformance42 of 122 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

March 2005V2 Messaging Conformance43 of 122 Optionality / Usage Relationship Conformance Usage codes are more specific than HL7 Optionality codes HL7 OptionalityAllowed Conformance UsageComment R - RequiredR O - OptionalR, RE, O*, C, CE, XO is only permitted for constrainable profiles C - ConditionalC, CE, R**, RE**** If satisfied by use case X – Not SupportedX B – Backward Compatibility R, RE, O*, C, CE, XO is only permitted for constrainable profiles W – WithdrawnX

March 2005V2 Messaging Conformance44 of 122 Usage / Cardinality Relationship Both Usage and Cardinality govern the appearance of a field in a message Cardinality constrained by the usage code If Required (R), the minimum and maximum cardinality for the element shall always be >= 1 If the usage of an element is not Required (R) (i.e. any code other than R), the minimum cardinality shall be 0 except in the following condition: where an element will not always be present but, when present, must have a minimum number of repetitions greater than one, this may be indicated by specifying –the non-required Usage code –the minimum cardinality representing the minimum number of repetitions when the element is present.

March 2005V2 Messaging Conformance45 of 122 Usage-Cardinality Combinations

March 2005V2 Messaging Conformance46 of 122 Usage Within Hierarchical Elements Messages are constructed using a hierarchy of elements At least one lower level element must be present for the higher level element to be considered to be present Adds an implicit conditional constraint on elements that enforce the presence of an element Places constraints on what combinations of usage codes may be used within a hierarchy

March 2005V2 Messaging Conformance58 of 122 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 and/or publish/subscribe systems. Prior to v2.5, the field was called Conformance Statement ID. For backward compatibility, the Conformance Statement ID can be used here.
