Definition:The codes for chemicals of importance to health care outside of medications, which were covered in the CHI Medication standard. For health care purposes these chemicals will be those found in the workplace or the environment that might be related to health. Commonly the first, and perhaps only use, of a chemical code would be during a first encounter and perhaps be part of a History and Physical. The conditional CHI chemical standard is the Environmental Protection Agency´s (EPA) Substance Registry System (SRS). See also http://www.epa.gov/srs/. Usability gaps noted were: Essential gaps that need resolution before removing conditional recommendation: 1) establishing interagency communication so that medical needs are addressed in a timely and coordinated fashion; developing a mechanism so that similar tables from other agencies can be matched against the SRS table and missing elements added; 2) investigate availability of a subset or view of information from the database in an acceptable format for healthcare use as a no or low-cost distribution item. (EPA is willing to provide this view as a periodically updated, perhaps every six-months, compressed file for Internet download.); and 3) requirement for registering an Object Identifier (OID) if it is to be used in HL7 messaging. Gaps identified that need addressing but do not prevent acceptance: 1) a task EPA is still undertaking is a review of the commonly regulated chemicals and the selection from the many synonyms available of an EPA Preferred Name. In the process we´re identifying ambiguities in naming (the same name applied to multiple chemicals) or in some instances a program used a name that is not appropriate for a particular chemical (e.g., its a name used by a completely different chemical). These kinds of problems really highlight the need for an Agency-wide system like SRS and the need for someone to review any changes to chemical content in SRS; and 2) an introduction of common chemical download format such as the MOLFIL or developing CXML (Chemical XML).
