Varicella Notification Message Mapping Guide
















VERSION: The version of this Message Mapping Guide is Draft 0.6 dated 6/5/2007.







This Message Mapping Guide describes the content and message mapping specifications for the fixed set of data elements used to communicate information to meet the requirements for Varicella Individual Case reporting to CDC. The intended audience for this document are the state/local and CDC programs and other public health related organizations interested in using the HL7 V2.5 case notification message specification for transmitting their data elements.









References







Version 1.0 of the Message Specification Guide is used to inform the mapping methodology for this guide.

Subject-related
This tab provides the mapping methodology for the demographic variables requested by the program.
Generic Obs.
This tab provides the content for the generic investigation questions. The ones that are not used for this particular instance are greyed out.
Varicella Observations
This tab provides the mapping methodology for the case/investigation content requested by the program for this specific notification.
Varicella Lab Report
This tab provides the mapping methodology for the content specific to a Varicella associated laboratory report.
Notification Structure
This tab provides the structural elements for the Notification. These variables are not negotiable. Default values are provided for HL7 structural elements that are required but not part of the surveillance data requested.









Variables as Observations







Other than the variables that map to the Patient Identifier segment (see Subject-Specific tab), all other variables are passed as a series of OBX-Observation/Result segments that are logically tied to the OBR-Observation Request “section header” segment that immediately precedes it. This content presents the real differences between the messages since all types of Notifications are handled in a standard manner up to this point.

Date Version Description
4/20/2007 Draft v. 0.5 Now using the Value Set Name when referencing a value set, rather than using the Value Set Code. This aligns with what PHIN-VADS displays upon look up.
4/20/2007 Draft v. 0.5 Added "notification subject type" to the OBR-Notification structural data to bring the message structure in line with the Outbreak Management version of the ORU Case Investigation Report message.
4/20/2007 Draft v. 0.5 Changed all observations that use the CE value type in OBX-2 to CWE - coded with exception - to prepare for versioning of value sets. The additional fields are still optional at this point.
4/24/2007 Draft v. 0.5 Added "patient name type" to the Subject-specific data to account for the default value that must be provided in the message.
4/24/2007 Draft v. 0.5 Mapping change from PID-23 Birth Place attribute to using DEM126 to create an observation for Birth Country Needed to be able to support country codes, whereas the PID-23 Birth Place attribute is "string".
4/24/2007 Draft v. 0.5 Mapping change from DEM128 Deceased Date on the patient record to INV146 Date of Death collected as part of the investigation.
4/24/2007 Draft v. 0.5 No longer supporting the RE - required but may be empty concept. The Program Optional/Required column reflects what the source messaging document specifies.
4/24/2007 Draft v. 0.5 Removed NOT110 Record Type variable. This observation is no longer necessary as the Notification Type specified in NOT101 contains this information.
4/24/2007 Draft v. 0.5 Broke out the supplemental notification data from the Notification Type (NOT101). Created NOT098 Supplemental Notification Type to designate that associated laboratory or vaccine report information is being passed with the notification.
5/9/2007 Draft v. 0.6 "Sent to CDC for Genotyping" concept remapped from VAR161 to LAB508
5/9/2007 Draft v. 0.6 "Genotyping Sent Date" concept remapped from VAR162 to LAB509
5/9/2007 Draft v. 0.6 "Sent For Strain ID" concept remapped from VAR163 to LAB510
5/9/2007 Draft v. 0.6 "Strain Type" concept remapped from VAR164 to LAB511
6/5/2007 Draft v. 0.6 Created a Generic Observations tab and greyed out any generic surveillance questions that Varicella does not use. Only the Varicella-specific observations remain on the Varicella Observations tab.

Column Description
Program Variables Section
PHIN Variable ID PHIN element UID drawn from the coding system PH_PHINQuestions_CDC
Label Short name for the data element, which is passed in the message.
Description Description of the data element as in PHIN Questions.
Data Type Data type for the variable response expected by the program area
Prog. Req/Opt Indicator whether the program specifies the field as:
R - Required - mandatory for sending the message
O - Optional - if the data is available it should be passed
May Repeat Indicator whether the response to the data element may repeat. “Yes” in the field indicates that it may; otherwise, the field is not populated. Repeats require special processing.
Coded Concepts Concepts that the program uses in answer to a particular question that required a coded response.
Value Set Name Name of the pre-coordinated value set from which the response is drawn. The value sets and coding systems are accessible via the Public Health Information Network Vocabulary Access and Distribution Services at http://www.cdc.gov/PhinVSBrowser/StrutsController.do.
Data Validation Business rules used for validating data integrity
Message Mapping Methodology Section
Message Context Specific HL7 segment and field mapping for the element.
HL7 Data Type HL7 data type used by PHIN to express the variable.
HL7 Usage Use of the field for PHIN. Indicates if the field is required, optional, or conditional in a segment. The only values that appear in the Message Mapping are:
• R – Required. Must always be populated
• O – Optional. May optionally be populated.
HL7 Cardinality Indicator of the minimum and maximum number of times the element may appear.
• [0..0] Element never present.
• [0..1] Element may be omitted and it can have at most, one Occurrence.
• [1..1] Element must have exactly one Occurrence.
• [0..n] Element may be omitted or may repeat up to n times.
• [1..n] Element must appear at least once, and may repeat up to n times.
