ada-snodent Systematized Nomenclature of Dentistry (SNODENT)

Systematized Nomenclature of Dentistry (SNODENT) is owned, maintained and distributed by the American Dental Association (ADA). SNODENT is a vocabulary designed for use in the electronic environment - for electronic health and dental records. The intended purpose is to:

  • Provide standardized terms for describing dental disease
  • Capture clinical detail and patient characteristics
  • Permit analysis of patient care services and outcomes
  • To be interoperable with Electronic Health Records (EHR) and Electronic Dental Records (EDR)

CodingRationale CodingRationale

Identifies how to interpret the instance of the code, codeSystem value in a set of translations. Since HL7 (or a government body) may mandate that codes from certain code systems be sent in conformant messages, other synonyms that are sent in the translation set need to be distinguished among the originally captured source, the HL7 specified code, or some future role. When this code is NULL, it indicates that the translation is an undefined type. When valued, this property must contain one of the following values:

SRC - Source (or original) code HL7 - HL7 Specified or Mandated SH - both HL7 mandated and the original code (precoordination)

There may be additional values added to this value set as we work through the use of codes in messages and determine other Use Cases requiring special interpretation of the translations.

Ethnicity Ethnicity

In the United States, federal standards for classifying data on ethnicity determine the categories used by federal agencies and exert a strong influence on categorization by state and local agencies and private sector organizations. The federal standards do not conceptually define ethnicity, and they recognize the absence of an anthropological or scientific basis for ethnicity classification. Instead, the federal standards acknowledge that ethnicity is a social-political construct in which an individual's own identification with a particular ethnicity is preferred to observer identification. The standards specify two minimum ethnicity categories: Hispanic or Latino, and Not Hispanic or Latino. The standards define a Hispanic or Latino as a person of "Mexican, Puerto Rican, Cuban, South or Central America, or other Spanish culture or origin, regardless of race." The standards stipulate that ethnicity data need not be limited to the two minimum categories, but any expansion must be collapsible to those categories. In addition, the standards stipulate that an individual can be Hispanic or Latino or can be Not Hispanic or Latino, but cannot be both.

Annex A specifies the methodology for and structure of the RDD Dictionary, and specifies how further Terms may be defined under the governance of a Registration Authority, requirements for which are described in Annex C.

Taken together, these specifications and the RDD Dictionary and Database make up the RDD System. Use of the RDD System will facilitate the accurate exchange and processing of information between interested parties involved in the administration of rights in, and use of, Digital Items, and in particular it is intended to support ISO/IEC 21000-5 (REL). Clause 6 describes how ISO/IEC 21000-6:2004 relates to ISO/IEC 21000-5.

As well as providing definitions of terms for use in ISO/IEC 21000-5, the RDD System is designed to support the mapping of terms from different namespaces. Such mapping will enable the transformation of metadata from the terminology of one namespace (or Authority) into that of another namespace. Mapping, to ensure minimum ambiguity or loss of semantic integrity, will be the responsibility of the Registration Authority. Provision of automated trm look-up is also a requirement.

The RDD Dictionary is a prescriptive dctionary, in the sense that it defines a single meaning for a trm represented by a particular RddAuthorized TermName, but it is also inclusive in that it can recognize the prescription of other Headwords and definitions by other Authorities and incorporates them through mappings. The RDD Dictionary also supports the circumstance that the same name may have different meanings under different Authorities. ISO/IEC 21000-6:2004describes audit provisions so that additions, amendments and deletions to Terms and their attributes can be tracked.

ISO/IEC 21000-6:2004 recognizes legal definitions as and only as Terms from other Authorities that can be mapped into the RDD Dictionary. Therefore Terms that are directly authorized by the RDD Registration Authority neither define nor prescribe intellectual property rights or other legal entities.

MEDCIN contains more than 175,000 clinical data elements arranged in a hierarchy, with each item having weighted links to relevant diagnoses. The clinical data elements are organized into six basic termtypes designed to accommodate information relevant to a clinical encounter. The basic termtypes in MEDCIN's terminological hierarchy are as follows:

Symptoms History Physical Examination Tests Diagnoses Therapy

Within this basic structure, MEDCIN terms are further organized in a ten level terminological hierarchy, supplemented by an optional, multi-hierarchical diagnostic index. For example, the symptom of "difficulty breathing" is placed in the terminological hierarchy as a subsidiary (or "child") finding of "pulmonary symptoms" although the presence (or absence) of difficulty breathing can related to conditions as diverse as myocardial infarction, bronchitis, pharyngeal foreign bodies, asthma, pulmonary embolism, etc. MEDCIN's diagnostic index provides more than 800 such links for difficulty breathing.

MULTUM Multum Lexicon

Broadly, the fields and values in the Multum Lexicon and the VantageRx Database are intended to be available for use in any HL7 message that includes a reference to non-veterinary drug products or active ingredients that are either approved for sale by the FDA or readily available in the United States. The following inter-related definitions recently circulated by us to the HL7 Vocabulary Technical Committee explain the scope of what we mean by "drug product" and "active ingredient." (A definition for "drug ingredient" is also provided here because the definition of "active ingredient" is reliant on this term.)

Drug Product A drug product is a manufactured or extemporaneously-compounded physiologically-active material intended by the preparer to achieve therapeutic, diagnostic, or preventative effects via biochemical mechanisms when applied to an epithelial surface or placed in an internal body space of a targeted organism.

Drug Ingredient A drug ingredient is a chemical compound or biologic agent that occurs in a drug product.

Active Ingredient An active ingredient is a drug ingredient that mediates one or more of the intended therapeutic, diagnostic, or preventative effects of a drug product and is present in sufficient quantities to achieve such effects according to the allopathic tradition of healthcare practice.

NMMDS Nursing Management Minimum Data Set

The NMMDS is the minimum set of items of information with uniform definitions and categories concerning the specific dimension of the context of patient care delivery. It represents the minimum data used to support the management and administration of patient/nursing care delivery across all types of settings. The NMMDS is composed of seventeen (17) data elements organized into three categories: environment, nurse resources, and financial resources. See Tables 1-3 for the elements and related definitions organized by each categories. The NMMDS most appropriately focuses at the first level of accountability for patient/client/family/community nursing care: this may be the delivery unit, service, or center of excellence level. The NMMDS supports numerous constructed variables as well as aggregation of data at the unit, institution, network, and system, etc levels. This minimum data set provides the structure for the collection of uniform information that influences quality of patient care, directly and indirectly.

Race Race

In the United States, federal standards for classifying data on race determine the categories used by federal agencies and exert a strong influence on categorization by state and local agencies and private sector organizations. The federal standards do not conceptually define race, and they recognize the absence of an anthropological or scientific basis for racial classification. Instead, the federal standards acknowledge that race is a social-political construct in which an individual's own identification with one more race categories is preferred to observer identification. The standards use a variety of features to define five minimum race categories. Among these features are descent from "the original peoples" of a specified region or nation. The minimum race categories are American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Other Pacific Islander, and White. The federal standards stipulate that race data need not be limited to the five minimum categories, but any expansion must be collapsible to those categories.
