This specification is a library of the HITSP defined data elements that are used for mapping to data elements from the HITSP selected standards. It defines data elements that have been constrained or used in other HITSP documents (such as Components, Transactions, Transaction Packages) and facilitates the consistent use of these data elements across the various HITSP selected standards. It does not attempt to specify all the data elements for the standards selected by HITSP (i.e. only those constrained). The Data Elements are organized into modules to simplify navigation, such as Medications, Advance Directives, Immunizations, etc.
This specification does not enable the use of the data elements; this is accomplished by a HITSP construct that is based upon a specific standard (such as HL7, X12N, NCPDP, etc.). In order to facilitate harmonization of value sets across the various selected standards, this specification may define value set constraints. When this does not occur, it is because the data element does not require a value set or a harmonized value set was not determined. These value sets in turn reference standard terminologies in HITSP/C80 Clinical Document Message Terminology. HITSP/C154 does not define any other constraints (such as optionality) as those constraints are identified in the HITSP construct that enables the data element.
There are many ways that various HITSP documents may constrain a data element, some examples include:
HITSP/TN903 Data Architecture provides a more detailed explanation about the use of data elements (and other data architecture concepts) within HITSP.

This section describes the conformance criteria, which are objective statements of requirements that can be used to determine if a specific behavior, function, interface, or code set has been implemented correctly.
In order to claim conformance to this construct specification, an implementation must satisfy all the requirements and mandatory statements listed in this specification, the associated HITSP Interoperability Specification or Capability, its associated construct specifications, as well as conformance criteria from the selected base and composite standards. A conformant system must also implement all of the required interfaces within the scope, subset or implementation option that is selected from the associated Interoperability Specification.
Claims of conformance may only be made for the overall HITSP Interoperability Specification or Capability with which this construct is associated.
A HITSP Interoperability Specification or Capability must be implemented in its entirety for an implementation to claim conformance to the specification. HITSP may define the permissibility for interface scoping, subsetting or implementation options by which the specification may be implemented in a limited manner. Such scoping, subsetting and options may extend to associated constructs, such as this construct. This construct must implement all requirements within the selected scope, subset or options as defined in the associated Interoperability Specification or Capability to claim conformance.
The key words SHALL, SHALL NOT, SHOULD, SHOULD NOT and MAY are to be interpreted as described in RFC 2119 and will appear when used in that fashion in this TYPEFACE.
The key words REQUIRED and OPTIONAL are also to be interpreted as described in RFC 2119 when they are used to indicate the optionality of components used in an exchange.
Constraints in this document will appear as shown below.
|C83-[DE-7.04-1]||The problem type SHALL be coded as specified in HITSP/C80 section 188.8.131.52.4.1.2 Problem Type. The first portion identifies the type of artifact being constrained. The second portion is the identifier for that artifact, and the final portion is the sequence number of the constraint on that artifact within this document. Constraints specific to CDA usage will contain the string CDA before the final number|

The HITSP Data Dictionary defines the library of Data Elements that may be used by HITSP constructs in standards based exchanges. The Data Elements are organized into modules to simplify navigation, such as Medications, Advance Directives, Immunizations, etc.
The personal information module contains the name, address, contact information, personal identification information, ethnic and racial affiliation and marital status of the person. See the HL7 Continuity of Care Document Section 2.5 for constraints applicable to this module.
This module indicates the language spoken by the subject.
This module contains the patient's sources of support, such as immediate family, relatives and guardians. Support information also includes next of kin, caregivers and support organizations. Support providers may include providers of healthcare related services, such as a personally controlled health record, or registry of emergency contacts.
This module contains the healthcare providers involved in the current or pertinent historical care of the patient.
This insurance provider module contains data about the entities or other individuals who may pay for a patient's healthcare. Such entities or individuals may be health insurance plans, other payers, and guarantors, parties with financial responsibility, some combination of payers or the patient directly. This module is used to define which entity or combination of entities has any financial responsibility for a patient's care.
This module contains the allergy or intolerance conditions and the associated adverse reactions suffered by the patient.
This module contains relevant clinical problems. See the HL7 Continuity of Care Document Section 3.5 for constraints applicable to this module.
