1.1 Purpose
This document describes how HL7 Version 2.5 Chapters should be formatted in order to get a uniform layout, which in turn allows automatic generation of the HL7 V2.5 Database. For the automatic scanning and data extraction processing it is important to maintain consistency across all HL7 chapters.
To demonstrate the styles this document uses the same formatting rules.
All formatting is set by MS Word “styles”. (The use of a MS Word .DOT template file was found to be too unreliable). A set of macros is available (see the end of this document) to apply the styles to the document.
1.2 General Rules
To reduce the amount of formatting effort and to allow easy processing of HL7 Chapters no direct formatting should be applied. All necessary formatting shall be done by the help of MS Word “styles”.
1.2.1 Exceptions
Only a few exceptions are accepted. One is the numbering of the chapter. Others are identified later.
1.2.2 General Specifications and Settings
This HL7 Style Guide is for HL7 V2.5 documents.
This Style Guide assumes the use of MS Word 97 SR-2 or a later version of MS word (Office 2000, etc.).
Some settings are standard:
• The language is American English
• Hyphenation is enabled.
• Paper orientation is portrait
• “Fast saves” are disabled (keeps the documents to a minimum size)
• “Templates and Add-Ins ( automatic updates” is disabled.
1.2.2.1
1.2.2.2 Page Setup.
Top margin: 0.5" (1.27cm)
Bottom margin: 0.75" (1.91cm)
Left margin: 0.5" (1.27cm)
Right margin: 0.5" (1.27cm)
Gutter (for binding): 0.5" (1.27cm)
Header: 0.5 (0.63cm)
Footer: 0.5 (0.63cm)
1.3 Document Structure
1.3.1 Introductory Page and First Subchapter
Every chapter begins with an introductory page which names the number of the chapter, the name of the chapter and the responsible chairs and editors. The first paragraph specifies the purpose of the chapter. The formatting is as follows:
Heading 1 (consists of a soft end of line [SHIIFT+RETURN] and the heading, but is auto-numbered and sets the number "base" for the whole chapter)
3.

3.1 PURPOSE Heading 2
The black horizontal line is built up by a graphical box across the page with 5 mm in height. The list of chairs and the editors is a table with no borderlines. This allows for easy alignment.
To set the "base" numbering for a chapter, set the number a *one* place in each chapter, namely in the actual chapter number ("3.") with the style of "Heading 1". Go to Format->Bullets and Numbering->Customize->Start at.
1.3.2 Event/Message and Segment Definition Heading 3
The structure of the HL7 chapters consists of two parts. The first lists events, triggers and messages with the relevant message structures; the second part defines the segments, elements, components and subcomponents in detail.
1.3.3 Field Definitions
The field definitions for a segment have to be appended to the segment definition. It starts with the level 4 heading naming the segment after which the fields/elements are defined. No text is necessary.
1.3.3.1 PID-1 Set ID - PID (SI) 00104 Heading 4
All field definitions start with a level 4 heading consisting of four parts:
1) The data element identifier
2) the name of the data element
3) the type of the data element (in brackets)
4) the data element ID number
The four heading parts are separated by three spaces each.
The field definition header also contains an invisible entry for index generation. Look at the “Set ID – PID” heading above with Tools -> Options -> View -> All checked on.
1.4 Document properties
Title: The contents of this document, i.e. the name of the chapter
Topic: “HL7” and the corresponding version number
Author: The name of the editors.
1.5 Formatting
1.5.1 Text Indentation
Text following headings level 1 and 2 are flush left with no indentation; the MS Word style is “Normal”.
Text following level 3 headings and lower is formatted using "Normal Indented", indented 1/4" (0.63cm).
1.5.2 Message Definitions
Message definitions are in form of a table to simplify the document data extraction This table consists of three columns and as many rows as necessary.
The first row (“Msg Table Header”) describes:
• in the first column the message type, the event/trigger code and the message structure ID separated by "^",
• in the second column a short description
• in the third column the corresponding HL7 chapter.
All subsequent rows are used for the message description (“Msg Table Body”). The segments used and structure symbols are listed in the left column. The middle column holds the segment name.
If this message applies to more than one event, all event codes are listed within the second field of the first column in the first row. Ranges are separated by dashes (“-“) and single values by commas.
The message definition tables are indented by 1/4" (0.63cm).
Msg Table Header Hyperlink to “EVN” Msg Table Body
|ADT^A01^ADT_A01 |ADT Message |Chapter |
|MSH |Message Header |2 |

| } | | |
|] | | |
Columns 1 and 2 are left justified - column 3 in centered
It is required that all segments in the message structure that are defined in the same chapter have a hyperlink to the segment attribute table.
Whenever brackets are used for one segment only they should appear within the same cell. Otherwise separate rows should be used.
Indentation can use tabs or spaces. The latter are preferred. If possible the closing brackets should appear below the corresponding opening bracket.
Please refer also to the Query and Response Grammar of Conformance Statements (section 1.8).
1.5.3 Segment Definitions
Attribute headers start on a new page. The attribute tables, i.e. the list of data elements used, are indented 1/4" (0.63cm) and should be formatted as follows:
Attribute Table Caption
Attribute Table Header
Attribute Table Body Bookmark (“EVN”) Index information
HL7 Attribute Table – EVN - Events
|SEQ |LEN |DT |OPT |RP/# |TBL# |ITEM# |ELEMENT NAME |
|1 |3 |ID |B | |0003 |00099 |Event Type Code |
|2 |26 |TS |R | | |00100 |Recorded Date/Time |
|3 |26 |TS |O | | |00101 |Date/Time Planned Event |
|4 |3 |IS |O | |0062 |00102 |Event Reason Code |
|5 |60 |XCN |O |Y |0188 |00103 |Operator ID |
|6 |26 |TS |O | | |01278 |Event Occurred |
The attribute table caption line information is used to generate the index of HL7 attribute tables. Therefore the complete caption is repeated in the index field. To facilitate the generation of the database the index field must be positioned at the end of the line!
The attribute table caption line must be bookmarked with the 3-letter segment ID (i.e. "EVN") for referencing by the message structure tables.
The header is shaded 10%.
The attribute table grid lines are ¾ points, and the border is a dual ¾ point line.
1.5.4 Field Definitions
Style “Heading 4” 1.5.10.0 starts with zero to ensure that “field definitions” after a HL7 Attribute Table are automatically renumbered. Where a zero-numbered heading is not desired, hide it with Format -> Font -> Hidden.
The Field Definition heading now consists of 5 components:
• Section heading number: 3.3.2.3 (automatically generated by Word)
• Element name: PID-3
• Element description: Patient Identifier List (Use Title Case)
• Element data type: (CX)
• Unique data element identifier: 00106
The 5 heading components are separated by 3 spaces each. The complete heading looks as follows:
3.3.2.3 PID-3 Patient Identifier List (CX) 00106
1.5.5 Components
Whenever a data element consists of components, they are defined first within the description. This definition is done in a paragraph like form. This definition also applies for subcomponents.
Components: ^ ^ ^ ^ ^
Components
1.5.6 Components (Data type)
The components which make up a data type are specified in form of a table like segments or real tables.
Component Table Caption
Component Table Header
Component Table Body Bookmark (“CE”) Index information
Hyperlink to “ST”
HL7 Component Table - CE – coded element
|SEQ |LEN |DT |OPT |TBL# |COMPONENT NAME |COMMENTS |SEC.REF. |
|1 | |ST |R | |identifier | | |
|2 | |ST |O | |text | | |
|3 | |IS |R |0396 |name of coding system | | |
|4 | |ST |O | |alternate identifier | | |
|5 | |ST |O | |alternate text | | |
|6 | |IS |O |0396 |name of alternate coding system | | |
Length: 250
Example:
|F-11380^CREATININE^I9^2148-5^CREATININE^LN|
The header is shaded 10%.
Columns 6 and 7 are left justified.
The attribute table grid lines are ¾ points, and the border is a dual ¾ point line.
Within the comments column there is no hint whether this component is itself a complex data type. The user can find out by checking the underlying data type. Within the narrative a hint (note) can be found to give an indication the data type which embeds the current one. But this should only apply to sparsely use data types.
1.5.7 Table Definitions
Whenever a table is referenced within a field description the first time (according to the sequence of chapters) the corresponding values have to be defined in form of a table. If no values can be identified this table should contain one entry saying “no suggested values”.
1.5.7.1
1.5.7.2 General rules
• Tables with double borders are normative, tables with single borders are user-defined.
• Each table consists of a caption, a header and a body.
• The header part is shaded.
• Table structures are to be inserted in the standard, even if values have not been determined.
1.5.7.3 HL7 Tables
HL7 Table Caption
HL7 Table Header
HL7 Table Body Bookmark (“HL70103”)
HL7 Table 0103 – Processing ID
|Value |Description |
|01 |Patient request |
|02 |Physician order |
|03 |Census management |
Note the index field in the HL7 table caption above.
The HL7 table caption line must be bookmarked with the 7-character table ID (ie. "HL70103", see 2.8.3.3) for referencing by all references (ie. HL7 Table 0103 – Processing ID) to that table within the same chapter.
The header is shaded 10%.
HL7 table grid lines are ¾ points, and the border is a dual ¾ point line.
As the width of HL7 tables changes, they are centered.
Note: HL7 Table 0136 - Yes/no Indicator should not be repeated with different values, rather the interpretations should be given in a “normal list” style. (This avoids the duplication of HL7 table 0136 with differing values.) Example:
Definition: This field indicates whether or not the patient’s identity is known. Refer to HL7 Table 0136 - Yes/no indicator for suggested values.
Y the patient’s identity is unknown
N the patient’s identity is known
1.5.7.4 User-defined Tables
User Table Caption
User Table Header
User Table Body
User-defined Table 0062 - Event reason
|Value |Description |
|01 |Patient request |
|02 |Physician order |
|03 |Census management |
Note the index field in the User Table caption above.
The user-defined table caption line must be bookmarked with the 7-character table ID (ie. "HL70062", see 2.8.3.3) for referencing by all references (ie. User-defined Table 0062 – Event Reason) to that table within the same chapter.
The header is shaded 10%.
User Table grid lines are ¾ points, and the border is a 1½ point line.
As the width of User-defined tables changes, they are centered.
It is a requirement that all user-defined tables are included in a chapter, even if values have not been determined. The tables should be formatted the same as any other user-defined table, but there should be only one "User Table Body" row, which should read: "No suggested values defined."
1.5.7.5 Other Tables
All other tables use the styles
• Other Table Caption
• Other Table Header
• Other Table Body
1.5.8 Table Value Definitions
We propose the following notation:
• The basic structure of a table is value in the left-most column and the description in the 2nd-leftmost column. Only one value pair per row is allowed. If comments, etc. are required, these can be entered in additional columns on the right.
• A range of values is indicated by three dots separated by spaces from the first and last value: …
A dash ("-") seems to be a bad solution because it may indicate a negative value.
• Different values with the same description can be separated by commas, eg. NO, NIL, NONE.
1.5.9 References to Data Elements
References to data elements are used within standard text shall be formatted like in PV1-6 - Prior Patient Location.
Reference Attribute
Here the character style “Reference Attribute” is used. This assignment of styles will be used later to identify incorrect references of data elements in accordance with the definition.
1.5.10 References to HL7 Tables
The same applies to the references to HL7 Tables within text like HL7 Table 0103 - Processing ID; the MS Word Style “Reference HL7 Table” is used.
1.5.11 References to User Tables
The same applies to the references to User Tables within text like User-defined Table 0062 – Event Reason; the MS Word Style “Reference User Table” is used.
1.5.12 Notes
Note
Note: The official title of UB is “National Uniform Billing Data Element Specifications.” Most of the codes added came from the UB-92 specification, but some came from the UB-82.
The “note” box is aligned with the text indentation. The bolded initial text "Note:" is followed by two spaces after the colon.
The “Note” style has 4 points before and 3 after each paragraph.
1.5.13 Examples
If an example is necessary to illustrate the meaning of a message the style “Example” should be used.
Example
MSH|.|..|...
EVN|..|..|...
PID|||.....
.....
Examples and use cases should be placed as close to the relevant chapter section as possible.
1.5.14 Page Headers
The header line consists of a ¾ point border line below. It merely names the document.
1.5.14.1 (This header is hidden!)
1.5.14.2 First Page Headers
The first page does not have a header.
1.5.14.3 Odd Page Headers
Chapter 3: Patient Administration
The number and name of the chapter is shown in the page header, right justified
1.5.14.4 Even Page Headers
Chapter 3: Patient Administration
The number and name of the chapter is shown in the page header, left justified.
1.5.15 Page Footers
Footer lines consist of two lines. The first lists a copyright statement and the page number with total number separated by a dash. The second line contains the status of this document as well as the issue date.
1.5.15.1
1.5.15.2 Odd pages and first page
The footer consists of different parts:
1) the copyright notice including the year and "All rights reserved."
2) a reference to Health Level Seven, Inc.
3) the version number
Health Level Seven, Version 2.5 © 2001. All rights reserved Page 3-5
Ballot May 2001
4) the release status
5) the chapter and page number formatted as “-”.
6) the month and year of release, Yk2 compliant and internationally readable.
1.5.15.3 Even pages
Page 3-6 Health Level Seven, Version 2.5 © 2001. All rights reserved
May 2001 Ballot
1.6 Lists
For listing items we provide four different styles:
“Normal List”
a) “Normal List Alpha”
• “Normal List Bullets”
1) “Normal List Numbered”
1.7 Indexing
Another important point for documentation is the generation of an index. For this a lot of additional information is necessary. To get a consistent result some rules have to be established how to formulate such entries.
In order not to interrupt the parsing process this information must be placed at specific points within the text.
The use of a colon (“:”) build up groups like a list of all tables.
1.7.1 Data Types
1) „Data Types:“ + + “ - “ +
2) + “ - “ +
3)
1.7.2 Data Elements
The name of the data element is repeated within the title.
1.7.3 Segments
Within the title three different entries are necessary:
1)
2) “Segments:” +
3) + “ (“ + +”)”
1.7.4 Attribute Tables
The index information must be added at the end of the paragraph (i.e. line).
1)
2) “HL7 Attribute Table:“ +
1.7.5 Events
1)
2) “Events:” +
1.7.6 Tables
1) “Tables: User or HL7 defined:” + + “ - “ +
2) ” + “ (“ + +”)”
1.7.7 Message Types
1)
2) “Message Types:” +
1.8 Conformance Statements
Conformance Statements are a new construct in version 2.4.
Three different conformance statements do exist:
• Query with tabular response
• Query with segment pattern response
• Query with display response
Every conformance statement consists of several distinct parts identified within the next section.
1.8.1 Distinct Parts of a Conformance Statement
The numbers within the right three columns specify the sequence order of the part within the conformance statement.
|No. |Part |Tabular response |Segment pattern |Display response |
| | | |response | |
|1 |introduction (= main table conformance statement) |1 |1 |1 |
|2 |query grammar |2 |2 |2 |
|3 |response grammar |3 |3 |3 |
|4 |QPD input parameter specification |4 |4 |4 |
|5 |QPD input parameter field description and commentary |5 |5 |5 |
|6 |output specification and commentary |6 | |6 |
|7 |virtual table |7 | | |
|8 |RCP Response Control Parameter Field Description and Commentary |8 | | |
1.8.2 Formatting the different parts of a conformance statement with styles
• Some fields are divided into two parts, i.e. the row now contains more cells
• A style is assigned to each field
• Some rows are inserted due to layout
• Some fields are spread over separate rows due to storage reasons for the database
The applied styles are inserted into the text and marked in red.
Some rows can be repeated as often as necessary. These rows are marked by a red arrow on the right side.
The table border is a dual ¾ point line. The grid lines are ¾ points single line.

1.8.2.3 Query Grammar
The query grammar is exactly the same as any normal message definition. This is especially true for the used styles. If a message should be used, which is defined somewhere else no additional definition is required because the definition in the main table refers to it.

| | | |Components: ^ ^ ^ < assigning authority (HD)> ^ ^ < assigning facility (HD)> |
| | | |The combination of values for PatientID, and PatientIDAssigningAuthority, are intended to |
| | | |identify a unique entry on the PATIENT_MASTER table. The PatientIDTypeCode is useful for |
| | | |further filtering or to supply uniqueness in the event that the assigning authority may have |
| | | |more than one coding system. (The PATIENT_MASTER table contains a constraint that prevents |
| | | |multiple patients from being identified by the same combination of field values.) This |
| | | |PATIENT_MASTER entry will be searched against on the PHARMACY_DISPENSE_TRANSACTION table to |
| | | |retrieve the rows fulfilling the query conditions. |
| | | |If this field is not valued, all values for this field are considered to be a match. |
| |ID |ST |If this field, PID.3.1, is not valued, all values for this field are considered to be a match. |
| |Assigning |HD |If this field, PID.3.4, is not valued, all values for this field are considered to be a match. |
| |Authority | | |
1.8.2.6 Response Grammar
The response grammar is much like any normal message definition, except the three additional columns. The column for group control is intended to specify an identifier which allows for requesting inclusion of whole groups of segments. The column for comments and support indicators are self-explaining.
This table also contains the message type definition, the event code and optional the message structure identifier in the upper left cell like in all the other message definitons.
If a conformance statements can make use of response message definition which is defined somewhere else, no additional specification is necessary.

6 REMARKS
7 A NOTE ON HTML STYLE SHEETS
Larry devised a style sheet that uses SOME of the above styles, with suitable modifications, for applying to HTML documents. Copies of this style sheet can be found in the HTML subdirectories where the HTML copies of the Standards Guide and Implementation Guide are saved.
To imbed the style sheet into an HTML document, make sure it is copied into the same directory as that document. Then, just above the tag, type the following sequence:
Styles for Heading 1-Heading 5 are in this sheet as modified -- since HTML does not support outline numbering, numbers must be manually added.
The HL7 style “Components” is incorporated into the HTML stylesheet as “definition.”
The HL7 style “Example” is incorporated into the HTML stylesheet as “defined term.” This has been modified to be in System font rather than LinePrinter, because the font the viewer sees it in depend on the fonts available on his machine; therefore Larry thinks it advisable to only use the most common fonts.
8 Formatting Macros (Style Fixer)
This part of this document contains the macros which help formatting the HL7 standard documents. These pages provide an easy access to the macros.
In order to make use of the macros you have to enable them during loading this file.
The macros operate on open files. Therefor the document(s) onto which these macros should be applied should be opened first.
1 General Remarks
It is not such easy to do some auto-format an already formatted documents. We can try to format tables if an indication is available. We also can try to adjust the properties of styles according to the rules established by the publishing group. But I can not guarantee that this will work in any case since Word has a built-in automatism which tries to correct the actions we execute.
Additionally some documents make intensive use of direct formatting, especially when creating numeric, alpha-numeric or bulleted lists without using the style “Normal List xxxx”.
Another fact to mention is that these macros apply a huge amount of corrections. As a result an error may occur saying that Word is not able to keep track of all changes. A possible solution is to save the file to disc.
Formatting tables assumes that the tables are “real” tables with the same number of columns each row (except conformance statements). Furthermore all cells within the same column should have the same width. If this requirement is NOT acceptable please let me know. I can change that but it would increase computation time!
So, PLEASE execute these macros on safe copy of the document!
2 Adjust the properties of the styles
This macro was generated by the help of “Get All Formats”. In contrast to it this one adjusts the properties according to the style guide.
Double click here. Whenever such a button-like frame appears, it hides the macros which can be activated by double-clicking onto the text inside!
Currently the styles for lists do not adjust the numbering or bulleting due to problems with the rest of the styles! A lot of paragraphs are formatted directly so that such an approach surprisingly displays funny results.
3 Format all Tables within the document
This macro formats all relevant tables. First of all the user is asked for the document to which the formatting should be applied. For this purpose a combo box will be displayed. After selecting the file out of the list a new dialog box will appear asking the user for the range of tables. Per default all tables are formatted, but the user can also reduce the set of tables. On ok the formatting rules will be applied to all the requested tables within this document.
Up to now I haven’t found a method to align the whole cell like it can be done by “Table->Mark whole table” and “center”, so this is left for manual correction. The correct rules are determined out of the formatting of the upper left cell of each table:
This task will take up to 5 to 10 minutes to apply the rules to all tables!
4 References
The next macro provides a dialog which allows for modifying the reference entries. It starts with a combo box for selecting the document. Next a dialog will be shown which guides through the formatting process:
If the necessary character styles are not available they will be created automatically.
The button “next” searches for the next text which corresponds to the format specified in the top frame (italics or bolded) and is not formatted as a reference (at least the left part of it). According to the text found the action to be performed will be selected automatically. The user has the opportunity to modify this selection by hand. On the one hand he can modify the action to be performed. On the other hand he can expand or shrink the selected text be the help of the four buttons at the top right corner of this dialog.
The button “apply” performs the specified modification of the styles on the selected text.
At this place it is important to mention that the styles are assigned to the exact selected text. Otherwise the usage of styles becomes worthless.
5 Adjust the numbering of the headings
The numbering of the different chapters requires a manual adaptation of the corresponding properties. This macro asks for the chapter number.
This macro currently does not adjust the tab stops. Therefor this macro should be applied before the following one.
6 Delete unused styles
This macro deletes all styles which are not used an more.
This task will take up to 3 hours to check each paragraph separately! It would be quicker just to delete the styles, but we want to keep the layout information we have entered so far. This is the only solution if the old and the new style are used in parallel.
7 Get All Formats
This macro should be used to generate a VBA procedure which can be used to adjust the styles of other documents. This macro appends VBA-code which can be copied to a new module to the end of the document. This code allows for copying the properties listed in the style guide.
This code does not adjust the properties, it just copies the values to the document in a readable form. Therefor it is not necessary to execute it!
8 Convert message tables into 6 column format
This macro should be used to convert the message tables into the six column format. It also reformats the table and assigns the correct styles as well as inserts the necessary headings.
The editor has to fill in the missing information by hand.
9 Requirements to run the macros
Running of the macros above requires VBA.
10 Manually Correcting Styles
The styles can be corrected by hand, too. Using “Format => Styles” displays a list of all used styles. Here you can modify the name of the styles by just typing in the correct name. Wherever the styles is used the new name is assigned.
11 Questions/Errors
Please let me know if there are questions or errors in applying these macros:
Frank.Oemig@
It would be helpful to submit the name of the macro and the name of the function and the line number – is possible.
12 History (last changes)
• formatting column width for attribute and message tables
• setting styles for conformance statements
• additional macro to insert three columns into message table (for group names), i.e. converting into 6 column format
