Multiple Cause of Death, 1993

 
 Data Set Name (DSN): CC36.MCMORT93

                  
 Multiple Cause Data

 The original scheme for coding conditions contained on the death
 certificate was designed with two objectives in mind. First, to
 facilitate etiological studies of the relationships among conditions,
 it was necessary to reflect accurately in coded form each condition
 and its location on the certification in the exact manner given by the
 certifier. Secondly, the codification needed to be carried out in a
 manner by which the underlying cause-of-death could be assigned
 through computer applications. The approach was to suspend the linkage
 provisions of the ICD for the purpose of condition coding and code
 certification.  This general approach is hereafter called entity
 coding.

 Unfortunately, the set of multiple cause codes produced by entity
 coding is not conducive to a third objective -- the generation of
 person based multiple cause statistics. Person based analysis requires
 that each condition be coded within the context of every other
 condition on the same certificate and modified or linked to such
 conditions as provided by ICD-9. By definition, the entity data cannot
 meet this requirement since the linkage provisions distort the 
 character and placement of the information originally recorded by the
 certifying physician.

 Since the two objectives are incompatible, DVS has chosen to create
 from the original set of entity codes a new code set called record
 axis multiple cause data. Essentially, the axis of classification has
 been converted from a entity basis to a record (or person) basis. The
 record axis codes are assigned in terms of the set of codes that best
 describe the overall medical certification portion of the death
 certificate.
                                    
 This translation is accomplished by a computer system called TRANSAX            
 (TRANSLATION OF AXIS) through selective use of traditional linkage and
 modification rules for mortality coding. Underlying cause linkages
 which simply prefer one code over another for purposes of undelying
 cause selection are not included. Each entity code on the record is
 examined and modified or deleted as necessary to create a set of codes
 which are free of contradictions and are the most precise within the
 constraints of ICD-9 and medical information on the record. Repetitive
 codes are deleted. The process may (1)  combine two entity axis
 categories together to a new category thereby eliminating a
 contradiction or standardizing the data; or (2)  eliminate one category
 in favor of another to promote specificity of the data or resolve
 contradictions. 

 Entity Axis Codes

 The original conditions coded for selection of the underlying 
 cause-of-death are reformatted and edited prior to creating the
 public-use tape. The following paragraphs describe the format and
 application of entity axis data. 

 FORMAT:  Each entity-axis code is displayed as an overall seven
 byte code with subcomponents as follows:

 1. Line indicator:  The first byte represents the line of the
    certificate on which the code appears. Six lines (1-6) are
    allowable with the fourth and fifth denoting one or two written
    in "due to"s beyond the three lines provided in Part I of the
    U.S. standard death certificate. Line "6" represents Part II of 
    the certificate.

 2. Position indicator:  The next byte indicates the position of
    the code on the line. i.e., it is the first (1), second (2),
    third (3),...eigth (8) code on the line.

 3. Cause category:  The next four bytes represent the ICD-9 cause code.

 4. Nature of injury flag:  ICD-9 uses the same series of numbers
    (800-999) to indicate nature of injury (N codes) and external
    cause codes (E codes). This flag distinguishes between the two
    with a one (1) representing nature of injury codes and a zero
    (0) representing all other cause codes.

 EDIT:  The original conditions are edited to remove invalid codes,
 reverify the coding of certain rare causes of death, and assure
 age/cause and sex/cause compatibility. Detailed information
 relating to the edit criteria and the sets of cause codes which
 are valid to underlying cause coding and multiple cause coding are
 provided in Part II of the NCHS Vital Statistics Instruction 
 Manual Series.  

 ENTITY AXIS APPLICATIONS:  The entity axis multiple cause data set
 is appropriate to analyses which require that each condition be
 coded as a stand alone entity without linkage to other conditions
 and/or require information on the placement of such conditions in
 the certificate. Within this framework, the entity data are
 appropriate to the examination of etiological relationships among
 conditions, accuracy of certification reporting, and the validity
 of traditional assumptions in underlying cause selection.
 Additionally, the entity data provide in certain categories a more
 detailed code assignment which is linked out in the creation of
 record axis data. Where such detail is needed for a study, the
 user should selectively employ entity data. Finally, the 
 researcher may not wish to be bound by the assumptions used in the
 axis translation process preferring rather to investigate 
 hypotheses of his own predilection.

 By definition, the main limitation of entity axis data is that an
 entity code does not necessarily reflect the best code for a
 condition when considered within the context of the medical
 certification as a whole. As a result certain entity codes can be
 misleading or even contradict other codes in the record. For
 example, category 5750 is titled "Acute cholecystitis without
 mention of calculus". Within the framework of entity codes this is
 interpreted to mean that the codable entity itself contained no
 mention of calculus rather that that calculus was not mentioned
 anywhere on the record. Tabulation of records with a "5750" as a
 count of persons having acute cholecystitis without mention of
 calculus would therefore be erroneous. This illustrates the fact
 that under entity coding the ICD-9 titles cannot be taken
 literally. The user must study the rules for entity coding as they
 relate to his/her research prior to utilization of entity data.
 The user is further cautioned that the inclusion notes in ICD-9
 which relate to modifying and combining categories are seldom
 applicable to entity coding (except where provided in Part 2b of
 the Vital Statistics Instruction Manual Series.

 In tabulating the entity axis data, one may count codes with the
 resultant tabulation of an individual code representing the number
 of times the disease(s) represented by the code appears in the
 file. In this kind of tabulation of morbid condition prevalence,
 the counts among categories may be added together to produce
 counts for groups of codes. Alternatively, subject to the
 limitations given above, one may count persons having mention of
 the disease represented by a code or codes. In this instance it is
 not correct to add counts for individual codes to create person
 counts for groups of codes. Since more than one code in the
 researcher's interest may appear together on the certificate,
 totaling must account for higher order interactions among codes.
 Up to 20 codes may be assigned on a record; therefore, a 20-way
 interaction is theoretically possible. All totaling must be based
 on mention of one or more of the categories under investigation.

 Record Axis Codes 

 The following paragraphs describe the format and application of
 record-axis data. Part 2f of the Viatal Statistics Instruction
 Manual Series describes the TRANSAX process for creating record
 axis data from entity axis data.

 FORMAT:  Each record (or person) axis code is displayed in five
 bytes. Location information is not relevant. The  Code consists
 of the following components:

 1. Cause category:  The first four bytes represent the ICD-9
    cause code.

 2. Nature of injury flag:  The last byte contains a 0 or 1 with
    the 1 indicating that the cause is a nature of injury category.

 Again, a maximum of 20 codes are captured on a record for multiple
 cause purposes. The codes are written in a 100-byte field in
 ascending code number (5 bytes) order with any unused-bytes left
 blank.

 EDIT:  The record axis codes are edited for rare causes and
 age/cause and sex/cause compatibility. Likewise, individual code
 validity is checked. The valid code set for record axis coding is
 the same as that for entity coding.

 RECORD AXIS APPLICATIONS:  The record axis multiple cause data set
 is the basis for NCHS core multiple cause tabulations. Location of
 codes is not relevant to this data set and conditions have been
 linked into the most meaningful categories for the certification.
 The most immediate consequence for the user is that the codes on
 the record already represent mention of a disease assignable to
 that particular ICD-9 category. This is in contrast to the entity
 code which is assigned each time such a disease is reported on two
 different lines of the certification. Secondly, the linkage
 implies that within the constraints of ICD-9 the most meaningful
 code has been assigned. The translation process creates for the
 user a data set which is edited for contradictions, duplicate
 codes, and imprecisions. In contrast to entity axis data, record
 axis data are classified in a manner comparable to underlying
 cause of death classification thereby facilitating joint analysis
 if these variables. Likewise, they are comparable to general
 morbidity coding where the linkage provisions of ICD-9 are usually
 utilized. A potential disadvantage of record axis data is that
 some detail is sacrificed in a number of the linkages.

 The user can take the record axis codes as literally representing
 the information conveyed in ICD-9 category titles. While knowledge
 of the rules for combining and linking and coding conditions is
 useful, it is not a prerequisite to meaningful analysis of the
 data as long as one is willing to accept the assumptions of the
 axis translation process. The user is cautioned, however, that due
 to special rules in mortality coding, not all linkage notes in
 ICD-9 are utilized.

 The user should proceed with caution in using record axis data to
 count conditions as opposed to people with conditions since
 linkages have been invoked and duplicate codes have been
 eliminated. As with entity data, person based tabulations which
 combine individual cause categories must take into account the
 possible interaction of up to 20 codes on a single certificate.

                    Beginning with 1992 data, some areas started reporting additional
                    Asian or Pacific Islander codes for race.  Codes 18 - 68 replace 
                    old code 08 for these areas.  Codes 78 replaces old code 08 for 
                    all other areas.  For consistency with Census races, code 09 
                    (all other races) has been imputed.
