Notes

Structure and Contents 

The 211 LA County Taxonomy: 

  • Is comprehensive with a logical niche for every concept. 
  • Incorporates terminology accepted in the field. 
  • Contains terms that are clearly named, defined, and cross-referenced. 
  • Differentiates between the services agencies provide and the target populations they serve, avoiding the common classification pitfall of splitting services which are essentially the same only on the basis of the different groups that utilize them. 
  • Begins with the perspective of how services are delivered rather than the funding streams they follow, the goals they are trying to achieve, the problems they attempt to resolve, or the organizational structure through which they are delivered.   
  • Structures terms in a hierarchical arrangement with mutually exclusive categories, making the logical relationship between terms an integral part of its structure and supporting easier and more reasoned indexing and retrieval once the structure is understood.   
  • Has a flexible structure which permits growth and change as the human services delivery system evolves. 
  • Can be customized to meet the unique needs of communities. 
  • Is designed specifically for an automated environment.

The Taxonomy contains more than 10,000 terms that are organized into a hierarchical structure that shows the relationships among terms. There are ten basic service categories with a separate section for target populations or beneficiaries:   

  • Basic Needs 
  • Consumer Services 
  • Criminal Justice and Legal Services 
  • Education 
  • Environment and Public Health/Safety 
  • Health Care 
  • Income Support and Employment 
  • Individual and Family Life 
  • Mental Health and Substance Use Disorder Services 
  • Organizational/Community/International Services 
  • Target Populations 

Each concept is broken down into up to six increasingly specific levels.  Not all sections include six levels. Some may, for example, have only two or three. The following example under Health Care illustrates the hierarchical arrangement: 

  Level I   L     Health Care 

 Level II  LR       Rehabilitation 

 Level III LR-8000     Speech and Hearing 

 Level IV LR-8000.0500    Audiology 

 Level V  LR-8000.0500-800     Sign Language Instruction 

 Level VI LR-8000.0500-800.05    American Sign Language


Types of Terms (Facets) 

The Taxonomy incorporates a faceted index to facilitate use and filtering by each of the following distinct domains.  Additional details are summarized in the full Taxonomy training and use documentation, and in the forthcoming HL7 Gravity Implementation Guide.

Service: Service indexing allows you to specify in detail what an organization does.   

Organization/Facility Type: Organization/facility type indexing allows you to specify what an organization is. It permits the user to filter entries by senior centers, hospitals, adult schools or other types of organizations.

Modality/Delivery Mode: The modality terms provide information about how a service is provided rather than the nature of the service itself. For example, you can search for programs that help people who are seeking a divorce and distinguish between those that provide legal counseling, mediation or actual representation in court.

Named Programs: Some Taxonomy terms carry the formal name by which particular programs (mostly those at the federal level) are generally known to professionals and end users alike, e.g., Medicaid, TANF.   

Target Populations: The last section of the Taxonomy contains target population terms which indicate the people for whom services are designed, the who facet. Examples include people with developmental disabilities, in a certain occupation, or who have been diagnosed with a specific health condition. 


Data Elements in the Taxonomy 

  • Term Identification Numbers (Codes): The alphanumeric codes mark the place and level of terms within the hierarchy. The computer has no way of knowing that Rehabilitation has anything to do with Health Care or that Speech and Hearing is a subset of Rehabilitation. But it can readily tell that LR-8000 is a subset of LR and that LR is, in turn, a subset of L. The ID numbers, not the terms, create the logic of the hierarchy.  
  • Term Names: The term names indicate the preferred wording for service concepts in the hierarchical display. An effort is made to select clear, unambiguous wording that accurately describes the service each term represents and to use terminology that is accepted in the field.   
  • Definitions: Definitions are provided for all terms and serve as a touchstone to ensure that different people are using terms the same way. They are descriptive of the way services are provided, not prescriptive for what services ought to be. Definitions are not a substitute for service narratives. Different organizations may offer the same service in different ways. The service narrative needs to describe these individual differences. 
  • See Also References: See also references identify related terms in other parts of the hierarchy. They help to assure that indexers and searchers have found the most appropriate term. 
  • Use References: Use references are synonyms for preferred terms in the hierarchy. They help to accommodate regional differences in the language and facilitate common language word/phrase searches using alternative terminology. There are more than 30,000 use references in the Taxonomy.
  • Facet: Each Taxonomy term is assigned to one of five facets which capture its intended use, as summarized above. 
  • Bibliographic References: Bibliographic References list source material for Taxonomy definitions and structure.  
  • Comments: The comments field provides information about a term including tips for indexers about how a term should be used or help in distinguishing the term from others that may be similar.


Additional Special Features

Related Concepts: Many organizations are accustomed to a classification system whose primary method of organization is by target group focus or problem: services for seniors, people who have disabilities, people who are homeless and so forth. These users may be disoriented by a taxonomy that is structured primarily by services. We have developed a set of target groups/problems and connected them with Taxonomy terms for services that are typically associated with those groups. Having access to the related concepts categories allows users to choose to look at the Taxonomy through a different lens.   

External System Crosswalks: 211 LA County has crosswalked the Taxonomy to six other classification structures: UWASIS which was published by United Way of America and is now out of print, the National Taxonomy of Exempt Entities (NTEE), published by the National Center for Charitable Statistics (NCCS) at the Urban Institute and the Nonprofit Program Classification System (NPC), also published by NCCS, the AIRS Problems/Needs List and the Canadian Problems/Needs List and the Health Related Social Needs crosswalk that used CMS funded programs to track the needs of patients whose social needs may be interfering with positive health outcomes.

U.S. and Canadian Locales: There are three versions (locales) of the Taxonomy: the U.S. English locale which includes terms and definitions that are appropriate for users in the United States, and two others that have been configured for use in Canada, one in English, the other in French.
